Specific embodiment
Below this utility model is further described the embodiment combined in accompanying drawing：
As shown in figure 1, this utility model mainly includes helical spring 1, drive gear 2, rubber friction disc 3, the and of spline housing 4
Starter planet axis 5.
Helical spring 1, drive gear 2 and spline housing 4 are from one end to the other side sequentially provided with starter planet axis 5, flower
The internal splined hole of key set 4 is connected with the external splines matching in starter planet axis 5 so that starter planet axis 5 and the energy of spline housing 4
It is enough to rotate together, meanwhile, spline housing 4 can be moved axially along starter planet axis 5.
Drive gear 2 is socketed in starter planet axis 5, and drive gear 2 fastens with glue rubber towards the end face of spline housing 4
Friction plate 3, rubber friction disc 3 is close to towards the end face of spline housing 4 with spline housing 4.
Starter planet axis 5 are provided with back-up ring 6, the end thereof contacts back-up ring 6 of helical spring 1, another end of end in contact drive gear 2
Face.Described one end of starter planet axis 5 is provided with positioning boss 7, under the pressure effect of helical spring 1, drive gear 2, rubber
Friction plate 3 and spline housing 4 are pressed on positioning boss 7.
The spline housing 4 includes the first shell portion 4.1 and the second shell portion 4.2, the diameter of the second shell portion 4.2
More than the diameter of the first shell portion 4.1.Spline housing 4 is provided with multiple deformation grooves 4.3 towards the end face of rubber friction disc 3, many
Individual deformation groove 4.3 is uniformly distributed along the circumferencial direction of spline housing 4.
