Problems solved by technology

Among them, for the rack and pinion steering system, due to factors such as the vehicle space and the design of the suspension system, the maximum steering angle at which the steering knuckle drives the wheels to turn is about 70° (for example, the inner wheel rotation angle is 40°, and the outer wheel rotation angle is 30°. °), which makes the turning radius of the wheel larger, causing the vehicle to have a relatively difficult problem when turning or turning around

Abstract

The invention provides a vehicle steering transmission mechanism, a vehicle steering system and a vehicle. The vehicle steering transmission mechanism comprises a main steering knuckle (1); the main steering knuckle is provided with a virtual main pin (11) and a mounting part which is used for being connected to a steering gear; the main steering knuckle can rotate around the virtual main pin to adjust a first steering angle; the vehicle steering transmission mechanism comprises a wheel fixing part, which is used for fixing a wheel and connecting the main steering knuckle and a sub steering knuckle (2) of the wheel; the sub steering knuckle is rotatably arranged on the main steering knuckle through a steering main pin (21); and the sub steering knuckle rotates around the steering main pinto be able to adjust a second steering angle relative to the main steering knuckle in the steering direction of the main steering knuckle. As the sub steering knuckle is rotatably arranged on the mainsteering knuckle, the vehicle steering transmission mechanism with the structure has an effect of improving the steering angle of the vehicle through running fit between the main steering knuckle andthe sub steering knuckle.

Description

technical field [0001] The present disclosure relates to the technical field of vehicle steering systems, and in particular, to a vehicle steering transmission mechanism, a vehicle steering system and a vehicle. Background technique [0002] As an important part of the vehicle chassis, the vehicle steering system's function is to provide the vehicle with the ability to change or maintain the driving direction. The steering system of a vehicle is divided into a mechanical steering system and a power steering system. After the steering force of the steering mechanism is properly transformed by the steering gear, the force and motion output through the steering gear are transmitted to the steering knuckles on both sides of the vehicle to drive the wheels. turn. Among them, for the rack and pinion steering system, due to factors such as the vehicle space and the design of the suspension system, the maximum steering angle at which the steering knuckle drives the wheels to turn i...
