Description
Technical field
The utility model relates to a kind of coupling, is specifically related to be used for the coupling of automobile electric booster steering system.
Background technique
Coupling is two axles that are used for connecting in the different institutions, makes it the mechanical parts of common rotation with transmitting torque.The servomechanism that automobile electric power-assisted steering (EPS) system generally adopts assist motor and turbine and worm decelerator to form, assist motor adopts coupling to be connected with turbine and worm decelerator.
Coupling (see figure 4) commonly used at present mainly contains three parts and forms: initiatively piece 1, damping pad 2 and Slave Block 3 are formed.The subject matter that this coupler structure exists: 1, initiatively piece and Slave Block all adopt steel material, and rotary inertia is bigger, and be bigger to the influence of switching-over speed of response; 2, initiatively the manufacturing of piece and Slave Block need be adopted special tooling and anchor clamps, and manufacturing process and assembly technology are all comparatively complicated, and cost is higher.
The model utility content
In order to improve the slow problem of electric boosting steering system switching-over speed of response; Reduce the manufacture cost of coupling, made things convenient for assembling and maintenance.The utility model coupling adopts new structure.
The technological scheme that the utility model adopted is:
The coupling that is used for automobile electric booster steering system comprises initiatively piece 1 and Slave Block 3, and initiatively piece 1 is connected with the output shaft of assist motor 5, and Slave Block 3 is connected with worm screw 6; It is characterized in that: said coupling also comprises connecting sleeve 4; Connecting sleeve 4 is a hollow circular cylinder, and its inwall is provided with axial internal gear 7; Said active piece 1 is cylindrical body with Slave Block 3, and initiatively a side of the outer wall of piece 1 is provided with external tooth radially, and a side of the outer wall of Slave Block 3 is provided with external tooth radially; The external tooth of said active piece 1 and Slave Block 3 cooperates with the internal gear 7 of connecting sleeve 4, and the three is fixedly connected.
External tooth quantity on said active piece 1 and the Slave Block 3 is 12; Internal tooth quantity on the internal gear 7 of said connecting sleeve 4 is 12.
Said active piece 1 all adopts nylon material with Slave Block 3; Connecting sleeve 4 adopts the GF/HNBR/PA66 composite material.
The utility model is reasonable in design, and is simple in structure, safe and convenient to use, owing to use new material, weight is lighter, solved the slow problem of conventional construction switching-over speed of response, lowered manufacturing and assembly cost simultaneously, and maintainalbility and practicability are good.
