Through the recess on the piston seat ball socket, in push rod and piston seat friction motion in-process, the grease of long-term storage can effectively lubricate push rod bulb and piston seat, and the piece that the friction produced in the working process also can effectively be stored to the recess.
To sum up, the utility model discloses an aspect realizes the link of push rod and piston through the piston seat, has solved the problem of the quick complete return of master cylinder piston, thoroughly eliminates because of the big piston of piston resistance not return or the bad problem of return.
Drawings
FIG. 1 is a novel piston seat of a master cylinder of the present invention;
FIG. 2 is an assembly view;
fig. 3 is an enlarged view of the ball claw structure.
In the figure: the ball-and-socket joint comprises a base body (1), a ball seat (2), a ball socket (3), a ball claw (4), a piston (5), a push rod (6) and a piston seat (7).
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
As shown in fig. 2, the partial structure of the implementation includes a piston 5, a push rod 6 and a piston seat 7, wherein the end of the piston 5 is provided with a mounting hole, the piston seat 7 is mounted in the mounting hole of the piston 5, the end of the piston seat 7 is fitted in the piston seat 7, the piston seat 7 is located between the piston 5 and the push rod 6, and the piston 5 and the push rod 6 are linked through the piston seat 7;
as shown in fig. 1, the piston seat 7 includes a base 1 and a ball seat 2, the base 1 is installed in an installation hole at the end of a piston 5 of the plunger type main cylinder assembly, the end of the ball seat 2 is provided with a ball socket 3, the ball socket 3 is connected with a ball head of a push rod 6 in a matching manner, the inner wall of the ball socket 3 is provided with ball claws 4, as shown in fig. 3, the ball claws 4 are mainly formed by fixedly connecting a plurality of claws on claw seats, gaps are formed between adjacent claws uniformly distributed at intervals along the circumference of the plurality of claws, the middle parts of the plurality of claws are provided with arc-shaped inward convex necks extending towards the center, the arc-shaped inward convex necks of the plurality of claws form necks of discontinuous annular ball claws 4, the necks are located at the connection part between the ball head part.
In the piston seat of the utility model, the ball socket 3 is matched and connected with the ball head of the push rod 6, and transmits the forward thrust and the reverse thrust of the push rod 6 when the main cylinder works; the ball claw 4 always holds the ball head of the push rod 6 in the working and returning processes of the piston, the returning force of the push rod 6 is transmitted to the piston of the main cylinder when the main cylinder returns, the working piston 5 can quickly and completely return, and the outer side of the ball claw 4 and the piston 5 can be in small clearance, transition and interference fit.
