Problems solved by technology

[0002] The traditional steering system transmits the steering action of the driver operating the steering wheel to the steering wheels through the steering mechanism. At the same time, the steering trapezoidal mechanism ensures a certain functional relationship between the inner and outer wheel angles during steering. , resulting in the interference of the suspension guide mechanism and the steering linkage system, which will have a certain impact on the ride comfort and operational stability of the vehicle

Abstract

The invention discloses a cable-driven steer-by-wire mechanism system for independent suspensions. The cable-driven steer-by-wire mechanism system for independent suspensions comprises a frame, a wheel, an axle, a master pin, a suspension link guide mechanism, a steering motor, a reducer and a cable drive mechanism. The master pin in in a double pin structure, namely including a main master pin and an auxiliary master pin. The cable drive mechanism is provided with two cables, two cable pulleys and two hoses and transmits power of the steering motor and the reducer to allow for steering of the wheel. The cable-driven steer-by-wire mechanism system for independent suspensions has the advantages that the double master pin structure and the cable drive mechanism enable additional steering caused by vertical jumping of the wheel to be small enough, even the additional steering is eliminated, impendent steering angle of the wheel is large-ranged, and the system is compact in structure, reliable in operation, convenient to assemble, low in cost and applicable to various independent suspensions.

Description

technical field [0001] The invention relates to a wire-controlled independent steering mechanism, in particular to a wire-controlled independent steering system that adopts cable transmission and is suitable for various independent suspensions. Background technique [0002] The traditional steering system transmits the steering action of the driver operating the steering wheel to the steering wheels through the steering mechanism. At the same time, the steering trapezoidal mechanism ensures a certain functional relationship between the inner and outer wheel angles during steering. , resulting in the interference of the suspension guide mechanism and the steering linkage system, which will have a certain impact on the ride comfort and operating stability of the vehicle. The independent steering system by wire control replaces the original mechanical connection between the steering wheel and the steering wheels with control signals, and the steering actions of the inner and ou...
