Example Embodiment

[0128] Example one,

[0129] In this embodiment, it can be considered that the first shaft segment 21 is initially in a position such as Figure 31 and Figure 33 In the disengaged position shown, the elastic biasing member 55 abuts the first bearing 53 against the stop flange 521 . If the motor rotates and drives the sleeve 52 to move down through the cooperation of the lead screw and the screw nut, the first shaft section 21 is driven to move down synchronously. When the first shaft segment 21 is in contact with the second shaft segment 22 , the switching from the separation position to the coupling position is completed. During this process, the elastic biasing member 55 is not deformed. If the clutch driving mechanism 51 drives the sleeve 52 to move downward, at this time, the first shaft segment 21 no longer moves axially with it, but the elastic biasing member 55 follows the mutual relationship between the first bearing 53 and the stopper 57 . move closer and be comp...

Example Embodiment

[0132] Example two,

[0133] In this embodiment, the first shaft segment 21 is fixed to the sleeve 52 , so the first shaft segment 21 moves synchronously with the sleeve 52 . The sleeve 52 moves synchronously with the nut or the screw on it. Therefore, by controlling the forward and reverse rotation of the motor and the duration of the rotation, the real-time position of the first shaft segment 21 can be controlled, so that the first shaft can be switched according to requirements. The engagement or separation between the segment 21 and the second shaft segment 22 .

[0134] It should be noted that the "thread nut" refers to the first thread nut 5122 and the second thread nut, and the "screw" refers to the first thread nut 5121 and the second thread nut.

[0135] According to the vehicle steering system 100 of the embodiment of the present invention, when the vehicle steering system 100 is a steer-by-wire system or a driving simulation system, on the one hand, the driving com...

Abstract

The invention discloses a vehicle steering system and a vehicle with the same. The vehicle steering system comprises a shell, a steering wheel and a steering wheel, at least one part of the transmission shaft is arranged in the shell, and the transmission shaft can rotate relative to the shell; the hand feeling simulation mechanism comprises a driving assembly and a driven part, the driving assembly is arranged on the shell, the driven part is matched with the driving assembly and fixed to the transmission shaft, and the driving assembly is in transmission connection with the transmission shaft through the driven part so as to simulate the hand feeling when the transmission shaft transmits torque; and the angle limiting mechanism comprises a rotating piece, the rotating piece is fixed to the driven piece, and the rotating piece is used for limiting the maximum rotating angle of the transmission shaft. The vehicle steering system can be used for simulating real hand feelings such as steering damping feeling and return force, and angle limiting of the transmission shaft is achieved when torque transmission of the transmission shaft is cut off. In addition, the structure of the vehicle steering system is more compact, the size is small, and the occupied space of the vehicle steering system can be reduced.

Description

technical field [0001] The present invention relates to the technical field of vehicles, and in particular, to a vehicle steering system and a vehicle having the same. Background technique [0002] In the related art, a driving simulation system such as a steering system of a game car has no mechanical connection between the transmission shaft and the steering gear, which cannot well simulate the steering feel during real driving, and the transmission shaft can be rotated by applying a small force to it. For the drive shaft, the user’s simulated driving experience is poor, and the steering system occupies a large space, which will increase the volume of the entire driving simulation system. SUMMARY OF THE INVENTION [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, an object of the present invention is to provide a vehicle steering system, which can effectively simulate the feel of real driving when ...
