Abstract

The invention relates to a vehicle double-kingpin differential independent steering system which comprises a steering gear assembly, a steering knuckle assembly and a steering tie rod assembly, a gear and rack steering power mechanism is designed and adopted for a conventional steering mode, a mandrel sliding column is driven to transversely move in the lateral direction of a vehicle, the steering tie rod assembly is driven to push and pull a whole steering knuckle, and the conventional steering mode is achieved; a differential power mechanism is adopted to drive a mandrel sliding column to drive a worm and gear mechanism in a steering tie rod assembly and a worm and gear mechanism in a steering knuckle assembly to rotate, so that a relative rotation angle is generated between a first steering knuckle and a second steering knuckle, and a large-angle steering mode is achieved. According to the system, the technical problem that the transmission pressure angle of the steering tie rod assembly is too large under the use requirement of a large steering angle is solved, the reliability of an independent steering system is improved, the burden of the steering system is reduced, active dynamic adjustment of a steering geometrical relationship can be realized, and a vehicle is more convenient to steer and more stable to run.

Description

technical field [0001] The invention relates to the technical field of automobile engineering, in particular to a dual kingpin differential independent steering system for a vehicle. Background technique [0002] The vehicle adopts an independent steering system, which enables the vehicle to have high maneuverability such as in-situ steering and lateral driving. The independent steering system mostly uses the rack-tie rod mechanism to push and pull the steering knuckle to rotate around the kingpin. However, when the wheel is in a large turning angle mode, it is restricted by the maximum pressure angle of the connecting rod mechanism, which will lead to poor force transmission characteristics of the mechanism and increase the steering system. Reduce the workload, reduce energy consumption, economy and driving reliability. [0003] For example, the patent JP6297306B2 discloses an independent steering system scheme using a rack-tie rod mechanism to push and pull the steering k...
