What is Car Wheel Track? What is the effect of car wheel base on a car?

The car wheel base is the distance between the centerlines of the trajectory left by the wheels on the vehicle support plane (usually the ground). If the ends of the axle are double wheels, the track is the distance between the two center planes of the double wheels. The wheel base of the car is divided into front wheel track and rear wheel track, the front wheel track is the distance between the center plane of the front two wheels, and the rear wheel track is the distance between the center plane of the rear two wheels, which can be the same or different.

Wheel base refers to the distance between the centerlines of the trajectory left by the wheels on the vehicle's support plane. The wheel base is divided into front track and rear track. The wheel base directly affects the ratio of the front and rear widths of the car.

Compared to other dimensions, the track is more influenced by the mechanical layout, especially the type of suspension system, and is a parameter that stylists need to determine at a very early stage. In general, the front track of passenger cars is slightly larger than that of the rear wheels (a difference of 10?).50mm), i.e. the front half of the body is slightly wider than the rear half, which is related to aerodynamics.

The length, width, height, and wheelbase of the car are the four elements that affect the riding space, but this is only the foundation, and the cabin contour must be carefully designed to design the cabin with plenty of space on the large body, which is the so-called "utilization" problem, and it is closely related to the overall layout of the whole car.

What is the impact of car wheel base on car analysis:

It has an impact on the space and comfort of the vehicle, as well as the handling.

1. After the length of the car is determined, the wheelbase is the most important factor affecting the riding space, because the occupant seats of the vast majority of 2-box and 3-box passenger cars are arranged between the front and rear axles. The long wheelbase increases the longitudinal space of the occupants, which will greatly increase the footroom that affects the ride comfort of the vehicle. While the wheelbase is not the only factor that determines the interior space, it is.

2. It is not denied that the car with a short wheelbase can make up for the problem of narrow interior space through some designs, but in general it is still limited.

3. At the same time, the length of the wheelbase has a great impact on the comfort and handling stability of the car. Generally speaking, the higher the class of the sedan, the longer the wheelbase. The larger the wheelbase, the larger the length of the compartment, the more spacious the seat space for the occupants, the better the anti-pitch and yaw performance, and the longer the wheelbase improves the stability of the straight cruising at the same time, the steering flexibility decreases, the turning radius increases, and the maneuverability of the car is also worse.

Therefore, it is necessary to find the right balance between stability and flexibility. Of course, on a high-end sedan with a long wheelbase, such a disadvantage has been compensated for by other high-tech devices.

Hello, 1, in fact, the car track is not necessarily a few centimeters between the front track and the rear track, the front and rear tracks are the same, the front track is slightly narrower than the rear track, the rear track is slightly narrower than the front track, this is set according to the different models, of course, the different wheel base sometimes directly affects its driving characteristics, often the front track is wide The car will feel more stable in the corner, but the wider the front track will be the accuracy of the steering will be relatively reduced, and the car with a wide rear track will be very high in terms of turning accuracy, This is also like the F1 traffic jam we all see, the front track is much narrower than the rear track, and the off-road vehicle is generally equal to the front and rear track, so that when passing through obstacles, it is easier to control its passing size;

2. Generally speaking, the front overhang of the front-wheel drive car is significantly longer than that of the rear-wheel drive car, and the front overhang of the rear-wheel drive car is shorter. Because the front-wheel drive engine is relatively forward, the front overhang has to take up a lot of space. Advantages of the front overhang: beautiful shape. Over potholes, speed bumps are particularly easy and smooth;

3. The larger the wheel base, the more favorable it is to the stability of the operation, and at the same time, it is also beneficial to the body shape and the spaciousness of the compartment, and the better the lateral stability. However, the wheel base is wider, and the total width and weight of the car are generally increased, and it is easy to have the problem of throwing mud to the side of the body. If the wheel base is too wide, it will also affect the safety of the car, so the wheel base should be adapted to the width of the body.

Hello, the size of the wheel base is related to the width of the vehicle, the vehicle with a large wheel base is generally more comfortable, and the wheel base is too large to affect driving safety.

Stability, operability and passability. It has a certain impact.

The difference in wheel track:

1. The wheel base is the distance between the center lines of the trajectory family bench left by the wheels on the vehicle support plane (generally the ground). If the ends of the axle are double wheels, the track is the distance between the two center planes of the double wheels.

2. Generally speaking, the wider and thicker the wheel base, the higher the driving comfort, but some domestic cars do not have directional assistance, and the steering wheel will be very "heavy" if the front wheel base is too wide, affecting the comfort of driving;

3. The wheel base is wide, the total width and total weight of the car are generally increased, and it is easy to throw mud to the side of the car Zhao shed. If the wheel base is too wide, it will also affect the safety of the car, so the wheel base should be adapted to the width of the body.

4. Wheelbase (mm): axle moment, which is the distance between the two perpendicular lines that pass through the midpoint of the two wheels on the same side of the vehicle and are perpendicular to the longitudinal symmetry plane of the vehicle.
