Abstract

The invention discloses a multi-axle steering mechanism and a structure parameter determination method of the multi-shaft steering mechanism. The multi-axle steering mechanism is simple in structure,easy to design and small in calculation amount. The multi-axle steering mechanism is used for being fixed on a vehicle frame (5) and driving wheels to steer, and the vehicle frame (5) comprises left,middle and right longitudinal beams (51, 52 and 53), front and rear transverse beams (54 and 57), at least a first intermediate transverse beam (55) and a second intermediate transverse beam (56). Anintermediate hydraulic lever mechanism (1), a front section steering mechanism (2), a middle section steering mechanism (3) and a rear section steering mechanism (4) which are arranged on the vehicleframe (5) are further included. The structure parameter determination method of the multi-shaft steering mechanism comprises the following steps of (10) determining the geometrical parameters of a hydraulic mechanism rod, (20) determining the geometrical parameters of a front section rod, (30) determining the geometrical parameters of a middle section rod and (40) determining the geometrical parameters of a rear section rod.

Description

technical field

[0001] The invention belongs to the technical field of automobile steering mechanisms, in particular to a multi-axis steering mechanism and a method for determining structural parameters thereof. Background technique

[0002] The steering mechanism of an automobile directly affects the driver's grasp of the direction during the steering process of the vehicle, which affects the steering accuracy at the slightest level, and directly poses a certain threat to the life safety of the vehicle and the driver at the worst. In the steering of multi-axle vehicles, it is necessary to ensure that the steering angles of the wheels on the left and right sides are different, and it must also conform to the steering principle of the Akaman car. This has very high requirements for the design of the steering system. Most of the multi-axle vehicles currently in use use a combination of electromechanical and hydraulic systems. Steering system, this type of steering system has a...
