The problem of the wheelbase of the car, the question about the poor wheelbase of the car

Automobile wheelbase difference detection method and device involve automobile performance testing technology. This method is equipped with each other parallel on both sides of the forward direction of the vehicle to be tested, the spacing is equal, and a group of detection signal lines corresponding to the left and right corresponding, when the vehicle vertical signal line passes, the front edge of the front edge and the rear edge of the left and right wheels on the front and rear axles are measured respectively, and then the center deviation value of the left and right wheels is obtained, and finally the wheelbase difference is obtained. The device used is:

Laser, photosensitive, photoelectric switch, deformation, strain, contact switch and other detection devices. The method and device have the characteristics of fast, accurate and automatic detection of automobile wheelbase difference.

Automobile wheelbase difference detection method, it is characterized in that the signal generating device is placed on both sides of the forward direction of the vehicle to be tested, the signal generating device is composed of two groups of detection signal lines parallel to each other, the distance between the detection signal lines is equal, and the left and right correspondence one by one, and in the same straight line, when the vehicle under inspection is perpendicular to the direction of the detection signal line, the difference δs b of the front edge of the left and right wheels on the front and rear axles is measured, the difference δs h of the left and right wheels on the front and rear axles, the left and the rear edges of the front and rear axles are measured The center deviation value of the right wheel is δs 2 (s b δs h ) 2, and finally the wheelbase difference of the car is measured δs δs 1 δs 2.

It is difficult to adjust to the repair shop, because it is the deviation of the car in the structure, this deviation is too big, if you buy a new car, you can find the 4S shop that sold you the car, they are obliged to solve the matter for you free of charge, this is a quality problem, is the warranty coverage.

Is it the leaf spring center screw broken, if not, then you go to the seller to negotiate to replace the car, it may be a factory problem.

Look at the rear wheel bow of your car to see if the center screw is broken, and the center screw is broken and the car will deviate

Problem description: Ask a professional. There is a difference in the left and right wheelbase in the manual inspection of automobile inspection.

According to the thousandth ratio, more than one thousandth means that it is unqualified.

In this case, with the values of the left axis and the right axis, what should the formula be like (in millimeters)?

The final result must be thousandths.

Thank you. Analysis:

Automobile wheelbase difference detection method and device involve automobile performance testing technology. This method is equipped with each other parallel on both sides of the forward direction of the vehicle to be tested, the spacing is equal, and a group of detection signal lines corresponding to the left and right corresponding, when the vehicle vertical signal line passes, the front edge of the front edge and the rear edge of the left and right wheels on the front and rear axles are measured respectively, and then the center deviation value of the left and right wheels is obtained, and finally the wheelbase difference is obtained. The device used is:

Chain stocking laser, photosensitive, photoelectric switch, deformation, strain, contact switch and other detection devices. The method and device have the characteristics of fast, accurate and automatic detection of automobile wheelbase difference.

Automobile wheelbase difference detection method, it is characterized in that the signal generating device is separated on the dismantling two sides of the forward direction of the vehicle to be tested, the signal generating device is composed of two groups of detection signal lines parallel to each other, the distance between the detection signal lines is equal, and the left and right correspondence one by one, and in the same straight line, when the vehicle being tested drives perpendicular to the direction of the detection signal line, the difference δs b of the front and right wheel front edges on the front and rear axles is measured, the difference δs h of the left and right wheels on the front and rear axles, the left and right wheels on the front and rear axles, The center deviation value of the right wheel is δs 2 (s b δs h ) 2, and finally the wheelbase difference of the car is measured δs δs 1 δs 2.

The difference in the left and right wheelbases means that the front and rear axles are not parallel, which will cause the vehicle to deviate, accelerate tire wear, produce additional load on the vehicle suspension, increase the driving resistance of the vehicle, cause the frame and suspension to deform, and even fatigue fracture. The stability of the vehicle is extremely poor when driving, and it may lose control at high speeds. This is a very dangerous thing to do, and it is important to go to the calibration table for calibration.

The difference in the wheelbase of the car should be caused by the imbalance of the four wheels:1The wheelbase is only one of the elements to measure the space, and the most direct ride experience has to be felt unconsciously.

I have to say that many models will now use some means similar to the above-mentioned seat changes in exchange for more eye-catching book data, which we really need to distinguish between wheels; 2.Consumers' power performance of the car is nothing more than acceleration, high-speed power reserve and other items, and many people directly use power and torque to measure the power performance of a car, the maximum power determines the maximum speed, and the maximum torque determines the speed of fighting; 3.The performance of the vehicle power can be a comprehensive data, not only related to power and torque, but also related to the vehicle weight and transmission response.

For example, the two models with similar power and torque have relatively better acceleration performance with small weight; 4.The gearbox's upshift response also determines the acceleration performance. For example, when cruising, the engine can reach peak torque output in less time if the transmission reacts quickly to downshifting.

On the contrary, they are hesitant and easy to miss the opportunity to overtake.

A wheel trajectory is the distance between the centerlines of the trajectory left by the wheels on the vehicle's support plane, usually the ground. If the ends of the axle are twin wheels, the tread is the distance between the two central planes of the twin wheels. In general, the wider the track, the more comfortable it is to drive.

However, there are some domestic cars that do not have directional power. If the front track is too wide, the steering wheel will be heavy, affecting driving comfort.

The size of the wheelbase affects the overall performance of the car: a wheelbase that is too short or too long can have an impact on the performance of a pruning car. If the wheelbase of the car is short, the length of the car will be short, the mass will be small, the minimum turning radius and the longitudinal passing radius will also be small, so the maneuverability of the car will be good.

However, the wheelbase is too short, the length of the compartment is insufficient, and the rear suspension (the distance between the axis of the last wheel of the vehicle and the last end of the vehicle) is too long, resulting in a large longitudinal swing when driving, a large mass transfer during braking, acceleration or uphill, and poor maneuverability and stability. If the wheelbase is too long, the length of the body will increase, resulting in a large rear reversing blind spot. Without the addition of reversing radar, reversing will be a severe test for beginners.

Wheel track is the distance between the centerlines of the trajectory left by the wheels on the vehicle's 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. Generally speaking, the wider the wheel base, the higher the driving comfort, but some domestic cars do not have a square shed mountain power, if the front wheel base is too wide, the steering wheel will be very heavy, affecting the driving comfort.

The size of the wheelbase of the car will affect the overall performance of the car: the wheelbase is too short and too long, which will have an impact on the performance of the whole vehicle. The wheelbase of the car is short, the length of the car is short, the mass is small, the minimum turning radius and longitudinal passing radius are also small, and the maneuverability of the car is good.

But if the wheelbase is too short, then the length of the compartment will be insufficient, and the rear overhang (the distance between the last wheel axis of the vehicle and the rear end of the car) will also be too long, which will cause the longitudinal swing when driving and the mass transfer when braking acceleration or the slope of regret is large, and its maneuverability and stability will deteriorate. If the wheelbase is too long, it will increase the length of the body, so that the rear reversing blind spot will also be larger, if the reversing radar is not increased, reversing is a severe test for novices.

Dear, this question is up to me, it takes a little time to type, please be patient, thank you!

Hello, the wheelbase is different, it will cause deviation to rent Peiqiao, tire eccentricity and the wheelbase of the car is not the same, and the high-speed running will cause deviation, which is prone to accidents, and the wear and tear of the tires will also be aggravated, it is recommended to go to 4S maintenance: 1. The wheelbase is too short and too long, which will have an impact on the performance of the vehicle. The wheelbase of the car is short, the length of the car is short, the mass is small, the minimum turning radius and longitudinal passing radius are also small, and the maneuverability of the car is good. 2.
