The figure is as follows: 1. the piston comprises a body, 2 parts of an end cover, 3 parts of a spring, 4 parts of an elastic retainer ring, 5 parts of a sealing ring, 6 parts of a piston; 7. a piston limit ring; 1a, assembling a guide inclined plane; 1b, an elastic retainer ring limiting groove; 1c, a limiting conical surface; 2a, assembling a positioning boss; 2b, an elastic check ring accommodating groove; 2e, positioning a boss by a spring; 2h, tensioning the inclined plane; 2f, a sealing ring mounting groove; 2g and a limit inclined plane.
Detailed Description
The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.
As shown in fig. 1-3, the utility model discloses an embodiment relates to a circlip end cover mounting structure of brake master cylinder, including body 1 and end cover 2, end cover 2's open end insert in body 1's the mounting hole, end cover 2's lateral wall middle part open and to have round circlip holding tank 2b, it has circlip restriction groove 1b to open on the corresponding mounting hole inner wall, circlip restriction groove 1b and circlip holding tank 2b between install circlip 4, end cover 2's open end lateral wall on be provided with one end sealing washer mounting groove 2f, circlip holding tank 2b be tensioning inclined plane 2h towards one side lateral wall of end cover 2 open end, when master cylinder circlip end cover 2 received internal pressure effect, expandable circlip 4.
The circlip receiving groove 2b can completely receive the circlip 4 when it is compressed.
And a limiting inclined plane 2g is arranged between the sealing ring mounting groove 2f and the elastic check ring accommodating groove 2b, and a limiting conical surface 1c matched with the limiting inclined plane 2g is arranged on the inner wall of the corresponding mounting hole.
A spring positioning boss 2e is arranged in the center of the closed end of the end cover 2.
The blind end outside of end cover 2 be provided with assembly positioning boss 2a between two parties, when end cover 2 installs, can realize preliminary location effect.
The inner side wall of the opening end of the mounting hole in the body 1 is provided with an assembly guide inclined surface 1a, and when the main cylinder elastic retainer ring end cover 2 is mounted, the elastic retainer ring 4 can be compressed and held tightly.
The body 1 is used as a main body part, the end cover 2 is fixed in the body 1 under the action of the elastic check ring 4 through the elastic check ring accommodating groove 2b and the elastic check ring limiting groove 1b, and the limiting inclined surface 2g and the limiting conical surface 1c are used for limiting the moving space of the end cover 2 in the axial direction; the sealing ring groove 2f bears the sealing ring 5 and achieves the sealing effect under the combined action with the sealing ring matching surface in the body 1; the spring 3 is limited in the action space under the combined action of the spring positioning boss 2e, the piston 6 and the piston limiting ring 7; the assembly guide inclined surface 1a is used for compressing and clasping the elastic retainer ring 4 in the assembly process; the tensioning ramp 2h is an expandable circlip 4 that prevents retraction of the circlip 4 when the end cap 2 is retracted.
