Detailed description of the invention
Below in conjunction with embodiment and respective drawings, the technical solution of the utility model is described in detail, to enable those skilled in the art's understanding clearly scheme of the present utility model.
The purpose of this utility model is the heavy motor vehicle Electric power-assisted steering transmission linkage providing a kind of dependable performance, compact conformation, saving installing space.This device includes bearing circle, steering column 2, steering inner articulated shaft 3, angle driver 4, angular transducer assembly 5, coupler 6.In actual use, steering operation is sent to steering column 2 and steering inner articulated shaft 3 by bearing circle, steering inner articulated shaft 3 again by one jiao of driver 4 by conduction orientation from vertically becoming level.After angle driver 4, connect steering inner articulated shaft 3, angular transducer assembly 5, steering inner articulated shaft 3 and another angle driver 4 successively.Angle driver 4 is herein connected with the T-shaped angle driver 13 in reducing motor assembly 16 by a coupler 6, is connected below T-shaped angle driver 13 by coupler 6 ' with manual steering gear 7 input end again.Connect one end of pitman arm 8 at the mouth of manual steering gear 7, the other end cylinder lever connecting rod 9 of pitman arm 8, and connect steering geometry 10 to reach the object of manipulating tires rotation by pull bar 9.The above-described steering transmission linkage consisted of said structure is simple and compact for structure, effectively can save installing space, and it is electronic with hydraulic pressure and the steering gear deposited relative to of the prior art, Electric power-assisted steering transmission linkage described in the utility model only relies on motor to provide power steering, relatively simple on apparatus structure, space is also more compact, also effectively can reduce the cost of later maintenance maintenance simultaneously.
