Problems solved by technology

Although this utility model can coordinate the angle relationship between the second front axle and the first front axle, it still has the following defects: in this utility model, the vertical arm taper holes of the second vertical arm are arranged on the upper and lower sides of the rotating shaft, and the upper and lower The layout structure makes it take up a lot of space, which is not conducive to the layout of the whole vehicle. At the same time, the straight tie rods of the first axle and the straight tie rods of the second axle are also arranged up and down, which makes the steering force uneven, which is not conducive to steering control

Embodiment 1

[0057] see figure 1 , figure 2 , Figure 9 , an arrangement structure of a passenger car double-tie rod steering system, comprising a steering gear 1, a steering drop arm 2, and an intermediate drop arm assembly 3, wherein the intermediate drop arm assembly 3 includes an intermediate drop arm bracket 31, a drop arm support shaft 32, The middle drop arm 33, the steering gear 1 is fixed on the left longitudinal beam 5 of the vehicle frame through the steering gear bracket 4, and the middle drop arm 33 includes a drop arm body 331 and a drop arm rotating end 332 connected to the vertical arm body 331 and its two ends respectively. The arm taper hole end 333, the vertical arm rotating end 332 is fixed on the middle vertical arm bracket 31 through the vertical arm support shaft 32, the middle vertical arm bracket 31 is fixed on the left longitudinal beam 5 of the vehicle frame, the vertical arm taper hole end 333 is provided with a No. 1 taper hole 335 at a position close to the...

Embodiment 2

[0059] Basic content is the same as embodiment 1, the difference is:

[0060] see image 3 , the first centerline 61 of the first straight rod 6 is coaxial with the second centerline 73 of the second straight rod 7;

[0061] see figure 1 , Figure 4 , the direction of the No. 1 tapered hole 335 and the No. 2 tapered hole 336 can be in the same direction or in different directions. The ball joint assemblies at both ends of the first straight tie rod 6 can be in the same direction or in different directions. The second straight tie rod 7 The direction of the ball head at the front end can be arranged according to the relative positional relationship of the straight tie rod, the tire, and the leaf spring front bracket.

Embodiment 3

[0063] Basic content is the same as embodiment 1, the difference is:

Abstract

An arrangement structure of a double-pull-rod steering system of a passenger vehicle comprises a steering machine, a steering vertical arm and a middle vertical arm assembly, wherein the middle vertical arm assembly comprises a middle vertical arm support, a vertical arm supporting shaft and a middle vertical arm; the steering machine is fixed into a vehicle frame left longitudinal beam through a steering machine support; the middle vertical arm comprises a vertical arm body, and a vertical arm rotating end and a vertical arm conical hole end which are connected with the two ends of the vertical arm body respectively; the middle vertical arm support is fixed to the vehicle frame left longitudinal beam; a conical hole 1 and a conical hole 2 are formed in the front end and the back end of the vertical arm conical hole end; one end of the steering vertical arm is connected with an output shaft of the steering machine; the other end of the steering vertical arm is connected with one end of a first straight pull rod; the other end of the first straight pull rod is fixed into the conical hole 1; one end of a second straight pull rod is fixed into the conical hole 2; the other end of the second straight pull rod is fixed into a conical hole in a front axle steering upper knuckle arm. The arrangement structure of the double-pull-rod steering system of the passenger vehicle not only occupies a small space and is conducive to arrangement of a whole vehicle, but also is uniform in steering force and light and convenient in steering manipulation.

Description

technical field [0001] The invention belongs to the technical field of automobile steering systems, and in particular relates to an arrangement structure of a passenger car double-tie-rod steering system, which is mainly suitable for solving the problems of large space occupation and cumbersome steering operation. Background technique [0002] Large buses over 9 meters usually adopt long front suspension structure, and the steering system of long front suspension bus can be divided into two types: "double tie rod structure" and "angle converter + horizontal steering machine + single tie rod structure". Highway buses and commuter buses generally adopt a double tie rod structure due to the high driving area. The key technology of the double-tie-rod steering system lies in the design and arrangement of the middle drop arm assembly, and the relative design arrangement positions of the first straight tie rod and the second straight tie rod. The length and relative position of th...
