Embodiment Construction

[0035] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. In the technical solution of the present invention, the above and below refer to: when the spring device of the suspension is applied to the vehicle, the one closer to the ground in the height direction of the vehicle is lower, and the one farther from the ground is upper.

[0036] Such as figure 1 As shown, the spring device of the suspension in this embodiment includes a spring support portion composed of an upper spring support portion 3 and a lower spring support portion 5 , and a suspension spring composed of an upper suspension spring 2 and a lower suspension spring 6 . The upper suspension spring 2, the upper spring support part 3, the lower spring support part 5, and the lower suspension spring 6 are arranged in sequence along the di...

Abstract

The present invention discloses a vehicle and a suspension thereof, a spring device of the suspension. The device comprises a suspension spring and a spring support portion. The suspension spring comprises an upper suspension spring and a lower suspension spring, the spring support portion comprises an upper spring support portion and a lower spring support portion which are detachably and fixedly connected at multiple positions, so that the length of the spring support portion can be adjusted, the upper suspension spring, the upper spring support portion, the lower spring support portion and the lower suspension spring are sequentially provided in the length direction of the spring support portion, one end of the upper suspension spring is matched with the upper spring support portion, the other end of the upper suspension spring is used for being matched with a vehicle body, one end of the lower suspension spring is matched with the lower spring support portion, and the other end of the lower suspension spring is used for being matched with the axle of the chassis. The deformation amounts of the upper suspension spring and the lower suspension spring can be changed when the length of the spring support portions is changed. By applying the spring device, the pretensioning force of the suspension spring can be adjusted, and quick and convenient disassembly and assembly are realized.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle and its suspension and a spring device for the suspension. Background technique [0002] The road conditions and working conditions often change complicatedly during the driving of the vehicle. Under these different road conditions and working conditions, when the force and moment transmitted from the road surface to the suspension through the tires are too large, it is easy to cause vibration and excessive roll of the vehicle body. And then the ride comfort of the driver and passengers is affected. The suspension on the vehicle can fully play the role of alleviating the impact of the road surface, reduce the vibration of the vehicle, and ensure the normal driving of the vehicle. [0003] Suspension is generally composed of three parts: suspension spring, shock absorber and guide mechanism. Determine an optimum preload value for the suspension springs. [0004] Howe...
