Detailed description of the invention
With detailed description of the invention, this utility model is further described below in conjunction with the accompanying drawings:
As shown in Figure 1, this utility model includes the most as shown in Figure 2 and Figure 6, push rod 1 and push rod deck 2, and push rod 1 head is provided with shape of a hoof hole a, being designed with two-stage step at shape of a hoof hole a, push rod deck 2 is sleeved in push rod 1 shape of a hoof hole a and carries out push-in cooperation by claw.
As shown in Figure 4, a outer face, shape of a hoof hole is equipped with the projection as first grade of step b as second gear step c, the both sides of shape of a hoof hole a inwall.As shown in Fig. 7～Fig. 9, push rod deck 2 takes the shape of the letter U body, and the one end open of U-shaped body is inserted for the pedal ball pin 3 of clutch, and ball hole d is closed and formed to the other end of U-shaped body, and ball is cheated d and coordinated with face, pedal ball pin 3 pommel.The both sides of one end that push rod deck 2 is provided with ball hole d are outwards respectively provided with back-off type claw e, back-off type claw e and are fastened at first grade of step b or second gear step c of shape of a hoof hole a.Back-off type claw e passes the both sides of push rod 1 head end at a of shape of a hoof hole and is provided with groove, and centre is catch.
This utility model fast joint structure by push rod 1 and push rod deck 2 with the use of, it is achieved clutch master cylinder is connected with the quick of pedal arm.
As shown in Fig. 2～Fig. 5, push rod 1 is formed by injection molding by fiberglass reinforced type nylon (PA66-GF35) material, push rod head designs special shape of a hoof hole a, coordinate the installation of push rod deck, two grades of steps it are designed with, it is achieved push rod deck 2 is at initial position and has assembled the spacing fixing of position in a of shape of a hoof hole.
Push rod deck 2 is formed by injection molding by acetal resin (POM) material, and push rod deck 2 global design becomes U-shaped, indoor design balling-up hole d, coordinates with pedal ball pin 3, it is achieved the flexible rotating after assembling.Two back-off type claw e it are designed with, it is achieved with the assembling of push rod 1 in U-shaped structure both sides.
