Abstract
The utility model discloses a belt tensioning structure of an automobile electric power steering system. The belt tensioning structure comprises a belt, a small belt wheel, a big belt wheel and a motor, wherein the small belt wheel is arranged on an output shaft of the motor and connected with the big belt wheel through the belt, and the belt, the small belt wheel, the big belt wheel and the motor form an eccentric type belt tensioning adjustment structure. The eccentric type belt tensioning adjustment structure is adopted, so the length of the center distance can be adjusted, the belt tensioning structure is easy to install and dismantle, and pretightening force can be adjusted for several times after the belt is loosened to meet an excellent working mode.
Description
Technical field
The utility model relates to a kind of motorcar electric steering boost system, and specifically, what relate to is a kind of belt tension structure of automobile electric booster steering system.
Background technique
In automobile running, divertical motion is the most basic motion.We handle and control the direction of travel of automobile by steering wheel, thereby realize the intention of travelling of oneself.The english abbreviation of electric boosting steering system is " EPS ", and the powered assistance motorist that it utilizes motor to produce turns to.This type systematic generally is made up of torque sensor, ECU (Electrical Control Unit) (ECU), motor, mechanical steering gear.
In the prior art, the belt type electric booster steering device adopts the working method of belt pretension, and the big small pulley of belt is according to required pretightening force fixed installation, and centre distance is fixed.The shortcoming of this mode: centre distance can not be adjusted, and difficulty is installed, and can not carry out tensioning after the belt slack once again and regulate.
The model utility content
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, and a kind of belt tension structure of automobile electric booster steering system is provided, and overcomes the problem in the above-mentioned background technology.
For realizing above-mentioned purpose, the belt tension structure of automobile electric booster steering system described in the utility model, comprise: belt, small pulley, big belt wheel and motor, described motor output shaft is provided with small pulley, described small pulley is connected with described big belt wheel by described belt, and described belt, small pulley, big belt wheel and motor form eccentric belt tension regulation structure.
Preferably, described eccentric belt tension regulation structure, the geometrical center of wherein said small pulley, big belt wheel departs from mutually with the assembly center of described motor.
Preferably, described small pulley installation shaft is provided with the adjusting parts of regulating for the belt pretightening force.
The utility model beneficial effect:
The utility model belt type electric booster steering device adopts eccentric belt tension regulation structure, can regulate centre distance length, easily installation and removal, and can after belt slack, carry out repeatedly pretightening force and regulate to satisfy the good operation mode.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with drawings and Examples the technical solution of the utility model is further explained, but following content is not used in restriction protection domain of the present utility model.
As shown in Figure 1, present embodiment provides a kind of belt tension structure of automobile electric booster steering system, comprise: belt 1, small pulley 2, big belt wheel 3 and motor, described motor output shaft is provided with small pulley 2, described small pulley 2 is connected with described big belt wheel 3 by described belt 1, and described belt 1, small pulley 2, big belt wheel 3 and motor form eccentric belt tension regulation structure.
In the present embodiment, described eccentric belt tension regulation structure, the geometrical center of wherein said small pulley 2, big belt wheel 3 departs from mutually with the assembly center 4 of described motor, forms a throw of eccentric 5.This throw of eccentric can operating mode according to actual needs design.
In the present embodiment, described small pulley 2 installation shaft are provided with the adjusting parts of regulating for the belt pretightening force.
In the present embodiment, described adjusting parts are screw or bolt.
In the present embodiment, the belt type electric booster steering device adopts eccentric belt tension regulation structure, can regulate centre distance length, easily installation and removal, and can after belt slack, can carry out repeatedly pretightening force by the adjusting parts and regulate to satisfy the good operation mode.Can not adjust thereby overcome in the prior art centre distance, difficulty is installed, can not carry out the problem that tensioning is regulated after the belt slack once again.
Although content of the present utility model has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple modification of the present utility model with to substitute all will be apparent.Therefore, protection domain of the present utility model should be limited to the appended claims.
