Embodiment Construction

[0039] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0040] The steering system is mainly composed of two parts: the steering gear and the steering transmission mechanism. The function of the steering gear is to increase the force transmitted from the steering wheel to the drop arm and change the direction of force transmission; the function of the steering transmission mechanism is to transmit the steering gear The resulting force is transmitted to the steering wheel to deflect it. The steering transmission mechanism is mainly composed of a steering drop arm, a straight tie rod, a steering knuckle arm and a tie rod.

[0041] The embodiment of the present invention provides a multi-axle steering system, aiming at the heavy-duty truck whose front half is carried by...

Abstract

The invention relates to the technical field of automotive steering and discloses a multi-shaft steering system. The multi-shaft steering system comprises a steering gear, a front steering axle, an auxiliary steering axle and a rear drive axle, and also an angular transducer, an electronic control unit and an executer, wherein the angular transducer is mounted beside the steering gear, and the executer is mounted on a tie rod of the auxiliary steering axle; the angular transducer is used for obtaining the steering information of the front steering axle and transmitting the steering information to the electronic control unit; the electronic control unit is used for controlling the executer to work according to the received steering information; the executer is used for driving the tie rod to move from side to side so that the auxiliary steering axle and the front steering axle are turned synchronously. The multi-shaft steering system is simple in structure, and the electrically control assisted steering mechanism of the multi-shaft steering system enables the axle spread arrangement of two steering axles not to be limited by space, and a dual-axle steering synchronization mechanism is completely realized by the electronic control unit and the executer without a connecting rod mechanism.

Description

technical field [0001] The invention relates to the technical field of automobile steering, in particular to a multi-shaft steering system and an automobile. Background technique [0002] Heavy-duty truck is the abbreviation of heavy-duty truck. The current heavy-duty truck is 6×2 (6 means the total number of wheels, and 2 means the number of driving wheels). connection to realize synchronous and coordinated steering; the second half is a single axle, which is a load-bearing drive axle. [0003] In the steering system of this structure, the steering of the front steering axle and the auxiliary steering axle is generally connected by a tie rod, and the steering device is complicated. Affected by the distribution of the vehicle, the wheelbase of the double steering axle is generally limited to between 1700mm and 2000mm. When the wheelbase of the double steering axle needs to be increased according to the layout of the vehicle, if a long tie rod is used for connection, the tie...
