Suspension system buffer device for vehicle and vehicle having same

Abstract

The invention discloses a suspension system buffer device for a vehicle and the vehicle with such suspension system buffer device. The suspension system buffer device comprises a vehicle body fixing seat, a steering knuckle fixing seat, a damper component and an elastic element component, wherein the damper component is arranged between the vehicle body fixing seat and the steering knuckle fixingseat and comprises a first damper and a second damper which are in serial connection, and each of the first damper and the second damper comprises an outer damper barrel and a damper piston rod movingin the outer damper barrel; the elastic element component comprises a first elastic element and a second elastic element, the first elastic element is arranged as first elasticity applied on the first damper to resist a compression state when the first damper is in the compression state, and the second elastic element is arranged as second elasticity applied on the second damper to resist a compression state when the second damper is in the compression state. The suspension system buffer device for the vehicle can improve riding comfort and driving performance of the vehicle effectively.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular, to a suspension system buffer device for a vehicle and a vehicle having the same. Background technique [0002] The car suspension is mainly composed of elastic elements, shock absorbers and guiding mechanisms. Since the road surface cannot be absolutely flat, the vertical reaction force of the road surface acting on the wheels is often impactful. In order to ease the impact, the suspension must be equipped with elastic elements (coil springs in general cars) and damping elements (shock absorbers). In order to pursue better comfort, we hope that the suspension can be "softer", but in order to pursue better driving performance, we hope that the suspension can be "harder". For most current cars, the damping coefficient and spring rate of the shock absorber are fixed. Even with variable pitch springs, the variation in stiffness is very limited. This also makes it difficult for a ...

Problems solved by technology

This also makes it difficult for a car with a single stiffness and a single damping coefficient suspension to achieve relatively good performance in terms of comfort and drivability.

With the advancement of science and technology, air suspension and electromagnetic suspension are also used in automobiles. These suspensions have excellent performance, but most of them contain electronic components, with complex structures and high costs.
