Problems solved by technology

At low speeds, the steering is not only laborious, but the driver has to turn the steering wheel significantly; while at high speeds, the steering sensitivity increases, but the stability and safety decrease accordingly.

Abstract

The invention discloses an active steering system based on an angle driver, and belongs to the technical field of automobile steering. The angle driver comprises a first input shaft, a driving bevel gear, a driven bevel gear and an output shaft. The driving steering system is characterized in that on the basis of the angle driver, the driving steering system further comprises a decelerating motor,a second input shaft and double rows of planetary gears; one end of the first input shaft is coaxially connected with a steering wheel, and the other end of the first input shaft is coaxially fixedlyconnected with the driving bevel gear; the driven bevel gear meshes with the driving bevel gear, and is coaxially fixedly connected to a planetary bracket of the double rows of planetary gears; an output shaft of the decelerating motor is coaxially and fixedly connected with a sun wheel of the double rows of planetary gears by the second input shaft; and the other sun wheel is coaxially and fixedly connected with an electric powering steering gear mounted on a connecting rod between two wheels of an automobile by the output shaft. The active steering function can be achieved on the basis of the angle driver, and the driving ratio can be adjusted by controlling rotation of the decelerating motor.

Description

technical field [0001] The invention belongs to the technical field of automobile steering, and in particular relates to an active steering system based on an angle transmission. Background technique [0002] At present, the steering gears of commercial vehicles over ten meters are all horizontal. Since the input angle from the steering wheel to the steering gear is too large, it is impossible to connect the steering wheel and the steering gear with a steering column, so the usual method is to connect the steering wheel with the steering gear in the middle. Add an angle drive to convert the transmission angle. The angle transmission is equivalent to a steering knuckle with a 90-degree power transmission function, and only plays a role in changing the direction of power transmission. [0003] In a traditional mechanical steering system of an automobile, the steering transmission ratio (the transmission ratio is the rotational speed ratio of the input shaft connected to the s...
