Description
Technical Field
The present invention relates to a chassis and a vehicle using the same.
Background
In the running process of the vehicle, the vehicle is required to quickly return to the straight running position under any steering operation working condition, so that the vehicle is required to have better aligning performance, and partial vehicle has larger aligning resistance and poor aligning performance due to the prior matching or the processing technology limitation of a steering system, thus the driver is required to provide additional operation actions and hand force to help the vehicle return to the straight running state, and the driving fatigue strength of the driver is obviously increased in the long-time running process.
In the prior art, the steering return performance is generally improved by increasing the caster angle of the kingpin and reducing the friction of a steering system, but the larger the caster angle is, the better the larger the caster angle is, and the larger the caster angle of the kingpin can cause new adverse problems, such as the problems of tyre abrasion, high-speed trembling and the like; the method for reducing the friction of the steering system by optimizing the steering gear processing technology is not obvious due to the limitation of the production technology level of the steering gear in China, and the phenomenon that the steering of the hydraulic power-assisted steering vehicle type with small aligning moment is slow or cannot be completely aligned is common.
A chinese patent publication CN2640874Y entitled "automotive axle damping steering mechanism" discloses an automotive axle damping steering mechanism comprising a pair of coil springs arranged between an axle and a transverse tie rod. When the vehicle turns, the transverse pull rod compresses the coil spring at the corresponding side, and the coil spring stores energy to provide power for vehicle alignment, so that the alignment capability of the vehicle is improved. The steering system of the vehicle has the aligning capability, the aligning force is insufficient to be a real problem existing in the vehicle when the vehicle cannot be completely aligned or steered at a small angle at the end of the aligning stroke, and the following problems exist when the aligning force of the vehicle is improved through a coil spring: the relationship between the restoring force provided by the coil spring and the compression amount of the coil spring is large, the restoring force is small when the compression amount of the coil spring is small, the restoring force is large when the compression amount of the coil spring is large, according to the actual working condition of the vehicle, the vehicle needs to be compensated for restoring force when the rotation angle is small (the rotation angle of the vehicle is small or the rotation angle of the large rotation angle is the tail of the restoring stroke), namely, larger restoring force compensation needs to be provided when the rotation angle is small, and the existing coil spring can only provide smaller restoring force compensation and cannot meet the use requirement when the rotation angle is small because the compression amount of the coil spring is small, if the elastic coefficient of the coil spring is increased, the steering resistance is overlarge when the rotation angle is large, and the cost is correspondingly increased.
