Off-road vehicle = at least independent cross beam, non-loaded body (preferably array frame), more than two differential locks (preferably mechanical), high torque engine, and part-time 4wd.
Multi-functional sports car SUV= tall body (the largest is full-size SUV such as Toyota Sequoia, Lincoln Tiger Pilot and so on. ) with four-wheel drive function (time-sharing, full-time) with one or two differential locks, in fact, the city is more suitable for them. There are also off-road vehicles in SUVs, such as Toyota's LC 100 LC 120 Land Rover's visit and so on. . .
CUV= These are all built on the automobile chassis by raising the chassis. The power of the compact class basically does not exceed 3.0. (Highlander is an SUV based on the B-class car platform. ) It is basically the same as a car, except that the passability is better. Don't be fooled by the four-wheel drive. . Without the differential lock, the four-wheel drive only increases the grip of the wet road. It is ok to run on wet roads. Don't even think about cross-country. You have to get down on the horizontal road. CUV is the only joint venture in China, and it is also a guide with some off-road nature.
My favorite SUVs are Unimok and Robin Hood of herdsman. Land Rover Defender is one. Toyota LC 100 LC 120 LC80 also counts.
Question 2: What is cross-country running? Cross-country rally refers to driving a vehicle in the wild. Most sites are hilly, mountainous and desert natural environments. There are cars, motorcycles and bicycles. I hope my answer can help you adopt it.
Question 3: What does cross-country mean? Hello, the car housekeeper team will answer your questions.
4h is a high-speed four-wheel drive, suitable for high-speed driving and stable body. 4L is a low-speed four-wheel drive, which is used when running bad roads.
Question 4: What is cross-country running?
Long-distance race in the wild natural environment. It is not only an independent competition, but also a training method often used in various sports. There is no fixed distance, and it is not limited by site equipment. Every practice or competition is based on the local natural environment conditions at that time to choose the route and determine the starting point and end point. In the early cross-country races, the organizers did not announce the route, distance and destination in advance. Before the race, they sent people to guide the way and distributed red and white paper along the way. The athletes followed the paper signs. Most of them run rough paths, climb obstacles, or cross jungles, or cross ditches and wooden bridges. The winner is the first to reach the destination. The current method is to determine the route, distance and date of holding first, and then conduct the competition under the condition of full preparation. Cross-country running is becoming more and more popular in many countries in the world. IAAF has a special cross-country running committee, which holds the World Cross-country Running Championship once a year, and the schedule is about 4km for men's adult group 12km and women's group. The scoring methods are mostly based on team competitions or stipulated by the organizers, and there is no world record. Cross-country running can not only improve human endurance and exercise internal organs, but also cultivate excellent qualities of courage, tenacity, sensitivity and hard work.
Edit the characteristics of cross-country running in this paragraph.
Orienteering is actually a long-distance intermittent running (you often need to stop to look at pictures or orient on the way). This kind of running in the fresh environment in the wild can make the muscles tense and relax, and the physical load and mental concentration alternate constantly. In this case, the whole body of all participants, especially the respiratory system and cardiovascular system, will get great exercise.
The benefits of cross-country running are similar to those of a treadmill, but compared with the boring long-distance running on a treadmill, cross-country running can exercise more muscles, the wild scenery is beautiful and the mood is naturally better. In long-distance running in the wild, because we need to meander forward and avoid rough sections, the inner and outer thigh muscles and hip flexors can get better exercise. In addition, you can exercise your waist and abdomen more, so that you can get stronger legs and waist and abdomen.
At the same time, cross-country running is also a good channel to exercise perseverance, patience and perseverance. By constantly overcoming psychological and physical difficulties during running, we can achieve the goal of surpassing ourselves and cultivate good will and spirit.
Basic requirements of cross-country running
Cross-country orienteering, like other long-distance running events, requires that on the one hand, it can reduce the consumption of human energy as much as possible and maintain a certain running speed, on the other hand, it can be accelerated according to the competition situation. Therefore, the following requirements should enable athletes to master hard in the training stage and pay attention to them at all times during the competition:
The posture mainly adopts a slightly forward or upright posture. Try to coordinate the movements of all parts of the body (head, trunk, arms, hips, legs and feet), and be good at using the supporting reaction and inertia generated during running to keep the body stable and improve the running effect.
It's best to breathe through your nose and breathe through your half-open mouth (lick your palate with the tip of your tongue). In addition to changing the frequency and depth of breathing when there is a physiological "pole" phenomenon in running (that is, increasing the exchange rate of gas by exhaling more), it should generally be natural breathing with appropriate depth and rhythm.
The distribution of physical strength is determined by the selected road section, or by the stage of the competition (starting point, way and end point), or by the different physical conditions. By alternating the working stage (muscle tension) and the rest stage (muscle relaxation) at the right time, we can run faster and save energy.
Generally speaking, the speed should not be too fast. Too fast or too fast on the way will not only affect the normal exertion of physical strength, but also seriously affect judgment. Some people have done experiments: it takes several times more time to do a math problem with the same difficulty in running than when it is still; If we speed up again, it will not only take longer, but also make more mistakes. However, for an experienced athlete, when the local conditions are favorable (for example, there are many reference materials and smooth roads, etc. ) He should run as fast as possible.
Rhythm According to experimental materials, people feel that the most suitable rhythm is 70-90 times per minute (that is, the duration of each step is 0.85-0.67 seconds). Too fast a rhythm is not easy to feel, and too slow will have an inhibitory effect. Rhythmic movements can not only save the energy consumption of the body, but also achieve the most appropriate movement coordination. Coordinated and rhythmic movements can give people a relaxed feeling and beautiful enjoyment.
This is a sense of distance ... > Keep a certain sense of distance in cross-country running. & gt
Question 5: What is a real off-road vehicle? Off-road vehicles must have four-wheel drive, and there is no off-road without four-wheel drive.
In fact, off-road vehicles are four-wheel drive vehicles, or all-wheel drive vehicles. Because some big trucks have six wheels or more, not necessarily four-wheel drive, but six-wheel drive. In the past, American Dodge captured a lot in the War of Liberation and the Korean battlefield, which was very common all over the country and was not scrapped until the 1970s. This kind of car is called "ten-wheeled truck" It's the third bridge, with eight children in the back and ten children in one child. Jiefang brand also has CA30, which is also three bridges and ten rounds.
Full drive, so that after one wheel slips in the mud, the other wheels can drive the car out of trouble, otherwise it will be towed away by others.
Cross-country, not only military, but also mining. Many mining vehicles are all-driven, and the third bridge has more precursors. Loading is also a problem. It is difficult to pull dozens or hundreds of tons of ore, and the design of two bridges is also difficult.
The principle of differential is that if the wheel loses enough friction, it will idle at twice the speed. Usually, all-wheel drive can solve the problem, but to improve the performance, it is necessary to have the function of differential lock to lock the differential. This equipment is of little use and is not complicated. All tractors designed for paddy fields in the south have this device. Cars have this, which is basically meaningless "full configuration", just like cigarette lighters, which are rarely used.
With all-wheel drive, you can leave cyclo-cross, but different layout designs have different results through ability.
First of all, the basic knowledge is that the chassis should be high, which depends on the tire diameter.
Theoretically speaking, the layout is to get three indexes: approach angle, departure angle and passing radius.
Approach angle is the slope at which cars can climb (this climb is not the summit, but just close to success). It consists of the angle formed by the front wheel and the bumper. If the approach angle is small and the actual slope is large, the bumper will touch the ground before the wheels go uphill.
Take the wall as an example. No car can have a 90-degree approach angle. The wheels don't touch the wall at all, so the bumper can't get on the wall. The car must have hit the wall.
And if the front wheel is trimmed outside the car body and can touch the wall first, then there will be 90% approach angle, and theoretically it can climb the wall.
The departure angle is opposite, and the rear wheel consists of the rear edge of the car, which determines how far the car can leave. If this angle is not enough, then when the car turns to a flat road after going downhill, the car body will scrape to the road before the rear wheel reaches the flat road, and the rear wheel will become a "hanging temple". The car seems to be stuck and can't move.
Question: What does suv mean? Do you mean cross-country city? SUV can be understood as an urban off-road vehicle. In fact, it is an off-road vehicle with comfort as its main function, which is different from a single-function off-road vehicle, such as JEEP military Hummer.
Question 7: What is cross-country running or cross-country sports car?
Question 8: What does four-wheel drive mean? Four-wheel drive, as the name implies, is that all four wheels of a car can get driving force. In this way, the power of the engine is distributed to the four wheels, and the wheels are not easy to slip when the road conditions are bad, and the passing capacity of the car is greatly improved. Four-wheel drive systems are mainly divided into two categories: part-time 4wd and full-time four-wheel drive. At present, most of the four-wheel drive vehicles we use are half-time four-wheel drive vehicles. As long as the car has a special two-wheel drive and four-wheel drive switching lever or button, then the car is a four-wheel drive and a half-time four-wheel drive. The half-time four-wheel drive system is the most commonly used four-wheel drive system. Mitsubishi Pajero, L300, L400, basic land cruiser Prado, LC 100, LC70, LC75 are basic models (a four-wheel drive may have 4-6 models, such as five engines, gearboxes and car interiors of Pajero, which are completely different, and the car price can be nearly doubled). The use of half-time four-wheel drive can be divided into two States: one is two-wheel drive, and the car has only two wheels to get power, which is no different from ordinary cars; The other is the four-wheel drive, in which the power is evenly distributed between the front and rear axles of the car at a ratio of 50: 50. Half-time four-wheel drive has a long history. Its advantages are simple structure, high reliability, and more fuel saving after installing the flywheel hub. Full-time four-wheel drive is a four-wheel drive system that keeps the four wheels of the car running all the time. If you want to subdivide the full-time four-wheel drive system, it can be divided into two categories: fixed torque distribution (front and rear 50: 50 ratio distribution) and variable torque distribution (front and rear power distribution ratio is variable). Full-time four-wheel drive also has a long history and is relatively reliable, but it consumes a lot of fuel.
Question: What's the difference between an SUV and an SUV? The full name of suv is sport utility vehicle.
The direct translation is sports utility vehicle.
It's completely different from an SUV.
In addition to larger tires, suv has no spare trunk behind the high point of chassis.
In fact, it is no different from ordinary cars. They all use car chassis.
Generally, it is used in cities, and the off-road ability is not great. The so-called "both the appearance of off-road vehicles and the comfort of cars" comes from this. To put it bluntly, it is to satisfy the wishes of those pseudo-off-road people, such as BMW X series or Lincoln navigator. Going to a real cross-country track is shit.
Real off-road vehicles are rare. In addition to using big tires and high chassis to improve passability (just like SUV), we should also do * * * work in chassis design and engine power output. It can really ride on the ground in extreme road conditions.
Nowadays, most people in China buy cars by looking at their appearance. When they see that the wheels are relatively large and there is no * * * behind the high point of the chassis, they say it is an off-road vehicle or a jeep, which can be said to confuse the concepts of the two. . .
