Problems solved by technology

However, the above method is not only time-consuming and labor-intensive, a waste of manpower and time, but also solves the problem for a while. During the use of the car, with the aging of various parts, the problem of inconsistent heights between the left and right sides of the car body may also occur.

Embodiment Construction

[0012] Specific embodiments of the present invention will be described in detail below. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0013] According to relevant experiments and analysis, the present invention finds that there are two reasons for the height difference on both sides of the car, one is the uneven load on both sides of the car design, and the other is the deviation of the manufacturing accuracy such as the stiffness and size of the suspension on the left and right sides of the car . When the stiffness of the leaf spring on the heavier side of the axle is lower than the stiffness of the leaf spring on the lighter side of the axle and the difference is large, the height difference between the two sides of the vehicle will exceed the maximum allowable value.

[0014] In order to solve the above problems, the present invention...

Abstract

The invention provides a method for controlling the height difference of both sides of a vehicle, which comprises the following steps that: an axle is divided into a first side with a high weight bearing capacity and a second side with a low weight bearing capacity according to the weight borne by the axle; a first steel sheet spring and a second steel sheet spring are selected according to different rigidity, and the rigidity of the first steel sheet spring is more than that of the second steel sheet spring; and the first steel sheet spring is arranged on the first side of the axle, and the second steel sheet spring is arranged on the second side of the axle. In addition, the invention also provides a vehicle, wherein the rigidity of the first steel sheet spring is more than that of the second steel sheet spring. Not only are the method and the product easy to realize, but also a measure for preventing the height difference of both sides of the vehicle from exceeding a standard is taken, so that the time and energy of handling after problems are found are saved, and the method has better effect than that of a traditional method.

Description

technical field [0001] The invention relates to a method for controlling the height difference on both sides of a vehicle, in particular to a method for controlling the height difference on both sides of a vehicle by controlling the stiffness levels of leaf springs on both sides of the vehicle axle. In addition, the invention also relates to a vehicle, especially a truck. Background technique [0002] In the process of manufacturing and market quality information feedback, it is often found that the left and right heights of the car body are inconsistent. Especially for cargo vehicles, when the height difference between the left and right sides of the vehicle body is too large, it may even cause hidden dangers to safety. Therefore, the height difference between the left and right of the car is also used as an inspection index before the car leaves the factory. [0003] At present, because the factors that cause the height difference between the left and right sides of the ...
