Abstract

The invention discloses a vehicle frame connector on a shock absorber. A body of the connector is of a rotary body structure. An inner threaded hole is formed in the center of the body in the axial direction and is a through hole. The inner threaded hole is used for being connected with a screw rod. The bottom face of the body is connected with the lower end of a cylindrical section through a chamfered section. The upper end of the cylindrical section is connected with the lower end of a conical section through a circular arc section. The circular arc section is in smooth transition connection with the cylindrical section and the conical section. The conical section is of a big-end-down structure. The upper end of the conical section is directly connected with the lower end of the small cylindrical section. The upper end of the small cylindrical section is directly connected with the top face of the body. The height of the small cylindrical section ranges from 0.6 mm to 1 mm. According to the vehicle frame connector on the shock absorber, the upper end of the body is adjusted to be the small cylindrical section, and the height design of the small cylindrical section is reasonable; the outer circular face of the small cylindrical section is fixedly welded to a vehicle frame during welding, and the small cylindrical section can effectively block welding slag and prevent the welding slag from entering the inner threaded hole, so that the inner threaded hole is prevented from being damaged, and the screw rod can be smoothly screwed into the inner threaded hole.

Description

technical field

[0001] The invention relates to components on a shock absorber, in particular to a vehicle frame connection joint on a shock absorber. Background technique

[0002] The frame connection joint is an important part on the shock absorber, such as figure 1 As shown, the manufacturing material of the main body 1 of the existing frame connecting joint is 20 steel, the main body 1 is a revolving body structure, and its overall height H is 13.5mm. An M12 internally threaded hole 1a is opened in the center of the body 1 in the axial direction. The internally threaded hole 1a is a through hole, and the internally threaded hole 1a is used for connecting a screw.

[0003] The bottom surface of the body 1 is connected to the lower end of the cylindrical section 1c through the chamfered section 1b, and the diameter of the cylindrical section is 36mm; the upper end of the cylindrical section 1c is connected to the lower end of the conical section 1e through the arc section...

Embodiment Construction

[0016] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0017] Such as figure 2 As shown, a frame connection joint on a shock absorber, the body 1 of the joint is a rotary structure, the manufacturing material is 20 steel, and the overall height H of the body 1 is 13.5 mm. An internally threaded hole 1a is opened in the center of the body 1 in the axial direction. The internally threaded hole 1a is a through hole penetrating through the top and bottom surfaces of the body 1. The internally threaded hole 1a is used for connecting a screw. In addition, the parameter of the internally threaded hole 1a is M12*1.25-7H.

[0018] The bottom surface of the body 1 is connected to the lower end of the cylindrical section 1c through the chamfered section 1b, the parameter of the chamfered section 1b is 1*45°, and the diameter of the cylindrical section 1c is 36mm. The upper end of the cylindrical section 1c is connected t...
