Abstract
The invention relates to a vehicle steering system, in particular to an automobile semi-automatic steering gear. The invention adopts the structure of an electric power steering gear controlled by an active steering motor. Its action is controlled entirely by the vehicle main controller (ECU), which itself has no separate controller and no separate sensors. The active steering motor controls steering under the control of an automobile main controller (ECU), amplifies power assistance through a small-tooth-difference gear reducer, transmits steering force to a steering rod system through a mechanical steering device part of the active steering motor, and then transmits the steering force to wheels to realize steering action.

The purpose of invention
So an object of the present invention is provides a kind of vehicle semi-automatic electric diverter for vehicle.
Technical scheme and beneficial effect
The structure that the present invention adopts is the electric booster steering device of active steering electric machine control.By automobile master controller (ECU) control, itself does not have independent controller, does not have independent sensor fully in its action.The active steering motor is controlled under automobile master controller (ECU) control and is turned to, amplify power-assisted by the gear with small teeth difference retarder, steering effort is delivered to steering gear connection, passes to wheel again and realize handling maneuver through its manual steering gear part (ball-and-nut steering gear or rack and pinion steering gear).What active steering of the present invention mechanism adopted is steer motor-slowing-down structure; Its motor is that low-power machine can be brush motor, also can be brushless motor; Its slowing-down structure is small-sized gear with small teeth difference slowing-down structure, also can is planetary gear speed-reduction structure, cycloidal gear slowing-down structure, horizontal other slowing-down structures such as worm and gear slowing-down structure.The power steering motor that adopts can be brush motor, also can be brushless motor.What coupled retarder partly adopted is the worm and gear slowing-down structure, also can be other slowing-down structure.
Structure of the present invention is to be based upon on the basis of recirculating ball electric direction varying device, the structure of recirculating ball electric direction varying device is constant { sees part bearing pin 1 (8) among the figure, drive plate (9), ball-bearing casing 1 (10), worm screw (11), worm gear (12), assist motor (13), steering gear housing (14), side cover-rocker shaft branch unit (15), bolt and nut branch unit (16), ball-bearing casing 2 (17), loam cake (18), reducing gearbox (19), oil sealing (20), ball-bearing casing 3 (21), jam nut (22) }, increased automatic guidance part { controller 23 etc. }.
Semi-automatic electric diverter is a low-power machine (1) to be installed as steer motor at the input shaft place, replaces the chaufeur hand-power to handle deflector work.This steer motor and a cover little tooth difference speed reducer { are seen eccentric wheel among the figure (3), needle bearing 1 (4), inner gear (5), gear ring (6), roller (7), bearing pin 1 (8), drive plate (9) } be connected, can lower the velocity of rotation of handling electric direction varying device, increase rotating torque simultaneously.The drive plate of little tooth difference speed reducer directly drives bolt and nut branch unit (16) screw rod and rotates, and implements handling maneuver.Do not adopting sensor and sensor transmission device, motor and worm and gear slowing-down structure etc. are all constant.No longer include and relatively rotate angle and position limiting structure.The handling maneuver of this semi-automatic electric diverter is controlled by unified controller (CPU) (23).
