Abstract

The invention provides a mechanical four-wheel steering mechanism, and relates to the technical field of steering systems. The mechanical four-wheel steering mechanism is composed of a steering control mechanism and a wheel edge steering mechanism, and the functions of the two parts are mainly achieved through gear transmission and shaft transmission. The steering control mechanism is mainly composed of a steering clutch, and the steering clutch is located between a front steering transmission shaft and a rear steering transmission shaft. The wheel edge steering mechanism is mainly composed ofa planet-like gear mechanism, the planet-like gear mechanism is mainly fixed to a wheel edge, and a gear ring is an incomplete gear ring and connected with a steering knuckle through a steering pin.According to the mechanical four-wheel steering mechanism, the inherent defects of a traditional connecting rod steering trapezoidal mechanism are overcome, and the control stability and the steeringportability of an automobile are effectively improved.

Description

Technical field: [0001] The invention relates to the technical field of steering systems, in particular to a mechanical four-wheel steering mechanism. Background technique: [0002] For now, most of the research on the four-wheel steering system is concentrated in the field of motor vehicles, which are mainly divided into hydraulic, electric, electro-hydraulic and mechanical. Among them, the common disadvantages of hydraulic type, electric type, and electronically controlled hydraulic type are high cost and difficult installation and maintenance, especially the hydraulic type has particularly high requirements for sealing performance, while the mechanical type just overcomes these points. defect. [0003] Moreover, the existing mechanical four-wheel steering system is developed into an existing multi-link mechanism based on the four-link steering trapezoidal mechanism. It is still impossible to fundamentally overcome the inherent defects of the four-link steering trapezoid...
