Embodiment Construction

[0034] The steering gear of the automotive electronic steering system of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] As shown in FIG. 3 , the steering gear in the automotive electronic steering system includes a motor 1 , a reduction mechanism 2 , a transmission mechanism 3 and a bevel gear set 5 connected in sequence.

[0036] Wherein, when the car is turning, the motor 1 is rotated through the optimal angle relationship calculated by the ECU, and then the motion is transmitted to the car wheel 4 through the reduction mechanism 2, the transmission mechanism 3 and the bevel gear set 5, so that the wheel 4 turns.

[0037] The motor 1 and the reducer 2 can adopt a general structure, which need not be described in detail. The transmission mechanism 3 generally can use a pair of cross shaft universal joints, wherein one end connected with the bevel gear set can freely expand and contract for a certain length, so as ...

Abstract

The invention relates to a steering device of vehicle electric steering system, wherein it comprises connected motor, reducer, transmitter and taper gear. The motor is based on the steering signal, via reducer, transmitter and taper gear to steer the wheels. Compared with traditional method, since it has flexible motion of taper gear, the rotation can be over sixty degrees.

Description

technical field [0001] The invention relates to an automobile steering system, in particular to a steering gear in an automobile electronic steering system. Background technique [0002] The car steering system is the mechanism used in the car to change the direction of the car. According to the different steering energy sources, automotive steering systems can traditionally be divided into two types: mechanical steering systems and power steering systems. [0003] The mechanical steering system uses the driver's physical strength as the steering energy, and all the power transmission parts are mechanical, also known as the human power steering system. The power steering system is formed by adding a set of steering afterburning device on the basis of the mechanical steering system. [0004] The mechanical steering system generally consists of three parts, namely the steering mechanism, the steering gear and the steering transmission mechanism. The steering mechanism is th...
