Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile steering, in particular to a structure for improving steering stability. Background Art
[0002] At present, the steering system of non-independent suspension buses is composed of a steering wheel, a steering column assembly, a recirculating ball steering gear, and a straight tie rod assembly. The steering trapezoid is generally designed by the bridge factory and directly provided to the bus factory for selection and use. The steering trapezoid lacks a buffer mechanism, which makes the vehicle difficult to control and has poor controllability when the vehicle bounces up and down and sways left and right on uneven roads.
[0003] Based on this, in order to solve the problem that the vehicle bounces up and down, sways left and right, and the direction is difficult to control when the road is uneven, this design proposes a structure to improve the steering stability. Utility Model Content
[0004] The utility model aims to provide a structure for improving steering stability.
[0005] A structure for improving steering stability comprises: a front axle, a fixed bracket A, a fixed bracket B and a steering shock absorber, wherein the fixed bracket B is installed on the left side of the front axle, and the fixed bracket B is connected to the lower end of the front axle through the fixed bracket A, wherein the middle part of the fixed bracket A is connected to one end of the steering shock absorber, and the other end of the steering shock absorber is connected to the fixed bracket B.
[0006] Preferably, the upper part of the fixed bracket B is connected to one end of a steering straight tie rod, the other end of the steering straight tie rod is connected to one end of a steering vertical arm, the other end of the steering vertical arm is connected to a steering gear, the upper part of the steering gear is connected to one end of a steering column, and the other end of the steering column is connected to a steering wheel.
[0007] The beneficial effects of the above scheme are:
[0008] 1. The non-independent steering system of the utility model utilizes the characteristics of the steering damper to prevent the self-excited oscillation of the steering wheel of the automobile, and also has a strong attenuation effect on the transient oscillation of the steering wheel caused by road impact, preventing braking deviation. The torque fluctuation at the steering wheel end is significantly reduced, the hand feel is improved, and the controllability is enhanced. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The present invention is further explained in detail below in conjunction with the accompanying drawings of the specification, but the protection scope of the present invention is not limited thereto.
[0013] according to Figure 1 and Figure 2 As shown, a structure for improving steering stability comprises: a front axle 1, a fixed bracket A2, a fixed bracket B3 and a steering shock absorber 4, wherein the fixed bracket B3 is installed on the left side of the front axle 1, and the fixed bracket B3 is connected to the lower end of the front axle 1 through the fixed bracket A2, wherein the middle part of the fixed bracket A2 is connected to one end of the steering shock absorber 4, and the other end of the steering shock absorber 4 is connected to the fixed bracket B3; that is, the steering shock absorber 4 is added to the traditional steering system, and the steering shock absorber 4 is installed between the fixed bracket A2 and the fixed bracket B3 added to the tie rod and the leaf spring of the front axle 1.
[0014] Specifically, the upper part of the fixed bracket B3 is connected to one end of the steering straight tie rod 5, the other end of the steering straight tie rod 5 is connected to one end of the steering vertical arm 6, the other end of the steering vertical arm 6 is connected to the steering gear 7, the upper part of the steering gear 7 is connected to one end of the steering column 8, and the other end of the steering column 8 is connected to the steering wheel 9.
[0015] When passing through uneven roads, the impact of the road surface will cause transient oscillation of the steering wheel. At this time, the steering shock absorber 4 can play a role in attenuation in this state, prevent braking deviation, significantly reduce the torque fluctuation at the steering wheel end, and enhance control.
