Problems solved by technology

[0002] At present, the steering limit of the general vehicle wheel is realized by the limit screw. The inventor found that for the independent suspension vehicle, the axle knuckle and the wheel wheel set parts are relatively opposite to the frame, suspension swing arm, etc. The position is not fixed, and it is difficult to find a suitable position to arrange and accurately limit the position through the limit screw

Embodiment 1

[0035] Attached below Figure 1-Figure 7 The present invention is described in detail, specifically, the structure is as follows:

[0036] This embodiment provides a rotation limit structure, including a limit slide 1, an adjustment nut 2, a limit adjustment block 3 and a limit block 4, the limit slide 1 is threaded to the outside of the limit slide 1 and the adjustment nut 2 , a limit adjustment block 3 is provided below the adjustment nut 2 and is slidably connected to the limit slide seat, and the limit adjustment block 3 is fixedly connected to the adjustment nut 2, and the bottom plane of the adjustment nut 2 is fitted to the upper plane of the limit adjustment block 3, To limit the limit adjustment block 3 to slide upward and bear the axial force during the limit. A limit block 4 is arranged below the limit adjustment block 3 .

[0037] Specifically, the cross section of the limit slide 1 is circular, such as Figure 4 As mentioned above, a number of slideways 5 are e...

Embodiment 2

[0043] This embodiment provides a vehicle steering system, including the rotation limiting structure of the first embodiment, the limiting slide 1 is fixed on the outer side of the rotating shaft, the limiting block 4 is fixed to the steering rocker arm, and by limiting the steering The turning angle between the rocker arm and the rotating shaft is used to limit the steering of the wheels.

[0044] This embodiment also has the function of adjusting the limit angle while realizing the limit function, and will not be affected by the up and down jump of the wheel, and has excellent applicability.

Abstract

The invention discloses a rotation limiting structure and a vehicle steering system, and solves the problem that in the prior art, a limiting screw cannot be well applied to an independently-suspendedvehicle. According to the rotation limiting structure and the vehicle steering system, a limiting function can be achieved, and the limiting angle can also be adjusted. According to the technical scheme, the rotation limiting structure comprises a limiting sliding seat, wherein the circumferential outer side of the limiting sliding seat is in threaded connection with an adjusting nut, a limitingadjusting block in sliding connection with the limiting sliding seat is arranged below the adjusting nut, and the limiting adjusting block can move up and down along the limiting sliding seat; and a limiting block is arranged below the limiting adjusting block, one sides where the limiting adjusting block and the limiting block are mutually matched are provided with a plurality of trapezoidal teeth, and when the limiting block steers to a limit position, the limiting adjusting block attaches the trapezoidal teeth of the limiting block for limiting.

Description

technical field [0001] The invention relates to the technical field of vehicle steering, in particular to a rotation limiting structure and a vehicle steering system. Background technique [0002] At present, the steering limit of the general vehicle wheel is realized by the limit screw. The inventor found that for the independent suspension vehicle, the axle knuckle and the wheel wheel set parts are relatively opposite to the frame, suspension swing arm, etc. The position is not fixed, and it is difficult to find a suitable position to arrange and accurately limit the position through the limit screw. Contents of the invention [0003] In order to overcome the shortcomings of the prior art, the first object of the present invention is to provide a rotation limiting structure, which can not only realize the limiting function, but also adjust the limiting angle. [0004] The second object of the present invention is to provide a vehicle steering system, which limits the st...
