Embodiment Construction

[0021] Example 1 of the vehicle as figure 1 Shown: It includes a chassis and a body (not shown in the figure) set on the chassis. The driving area of ​​the body is provided with a steering wheel. The chassis includes an axle 8 and steering knuckles 10 at both ends of the axle. The steering wheel is connected to one of the steering knuckles for transmission. Connected, a steering pull rod 9 is arranged between the two steering knuckles. Between the axle 8 and the steering rod 9, there are a pair of first return compensating gas spring 1 and second return compensating gas spring 5, first return compensating gas spring 1, second return compensating gas spring 5 Arranged left and right, the vehicle axle is provided with a gas spring connecting plate 4 which is connected with each positive compensation gas spring, the gas spring connecting plate 4 is a horizontally arranged convex structure, and the narrow side of the gas spring connecting plate 4 is fixed on the axle by bolts 8, ...

Abstract

The invention relates to a chassis and a vehicle using the chassis. The chassis comprises an axle and steering knuckles arranged at the two ends of the axle. A steering pull rod is arranged between the two steering knuckles. A first return compensation gas spring and a second return compensation gas spring are arranged in a pair between the axle and the steering pull rod. The axle and / or the steering pull rod are / is provided with gas spring guide structures / a gas spring guide structure matched with the corresponding return compensation gas springs / the corresponding return compensation gas spring in a guided mode. The gas spring guide structures make the first return compensation gas spring in the first return compensation gas spring and the second return compensation gas spring supply return compensation force to the steering pull rod in the process that the steering knuckles steer leftwards and make the second return compensation gas spring in the first return compensation gas springand the second return compensation gas spring supply return compensation force to the steering pull rod in the process that the steering knuckles steer rightwards. The problem that small-angle compensation force is insufficient when return force compensation is supplied through springs in the prior art is solved.

Description

technical field [0001] The present invention relates to a chassis and a vehicle using the chassis. Background technique [0002] During the driving process of the vehicle, under any steering operation condition, the vehicle needs to quickly return to the straight driving position, which requires the vehicle to have a good return-to-alignment performance. Some vehicles have a large return-to-alignment resistance due to early matching or the processing technology of the steering system. , the whole vehicle has poor return-to-alignment performance, which requires the driver to provide additional operating actions and hand power to help the vehicle return to the straight-line driving state, and the driver's driving fatigue strength is significantly increased during long-term driving. [0003] In the prior art, the steering return performance is generally improved by increasing the caster angle of the kingpin and reducing the friction of the steering system, but the larger the in...
