Abstract
The utility model discloses a kind of parking and braking mechanism with spheric structure, comprise protecgulum, middle body, piston rod and housing assembly, push-rod assembly is provided with between described protecgulum and middle body, described push-rod assembly is connected with break swing arm by clevis, described piston rod to be enclosed within housing assembly and to be connected with release bolt assembly, be provided with epithelium between described push-rod assembly and middle body, wherein, the push rod dish of described push-rod assembly, epithelium and piston rod head phase-contact surface are spheric structure.The parking and braking mechanism of what the utility model provided have spheric structure, by arranging push rod dish, epithelium, piston rod head phase-contact surface be spheric structure, thus can ensure that push rod dish, epithelium, piston rod head are face contact at any time, improve the operating conditions of epithelium, effectively extend the working life of epithelium and arrester.
Description
Technical field
The utility model relates to a kind of parking and braking mechanism, particularly relates to a kind of parking and braking mechanism with spheric structure.
Background technique
The push rod of tradition air chamber push-rod assembly is tried to get to the heart of a matter face, and associated epithelium face, piston end women's head-ornaments are all plane.Because arrester push-rod assembly is connected by swing arm with break, and break upper friction plate in use progressively weares and teares thinning, often swing is there is in break swing arm when normally working, and the position also constantly variation in friction plate life cycle when braking enable, this just to cause with it by the push-rod assembly that clevis is connected also is operationally existence pendulum angle, but piston rod is rectilinear movement because its operating conditions limits, thus, push rod dish, epithelium, plunger rod contacts facial plane structure, under its actual working state, in its life cycle, most of the time piston rod and epithelium are point cantact, and point of contact is substantially in fixing scope, thus cause epithelium and plunger rod contacts point place earlier period damage, make arrester because of the damage of epithelium premature failure.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of parking and braking mechanism with spheric structure, can ensure that push rod dish, epithelium, piston rod head are face contact at any time, improve the operating conditions of epithelium, effectively extend the working life of epithelium and arrester.
The utility model is solve the problems of the technologies described above the technological scheme adopted to be to provide a kind of parking and braking mechanism with spheric structure, comprise protecgulum, middle body, piston rod and housing assembly, push-rod assembly is provided with between described protecgulum and middle body, described push-rod assembly is connected with break swing arm by clevis, described piston rod to be enclosed within housing assembly and to be connected with release bolt assembly, epithelium is provided with between the push rod dish of described push-rod assembly and middle body, wherein, described push rod dish, epithelium and piston rod head phase-contact surface are spheric structure.
The above-mentioned parking and braking mechanism with spheric structure, wherein, described piston rod is connected with middle body by guide pin bushing, and described housing assembly is aluminium alloy cylinder, described aluminium alloy cylinder and middle body are crimped together by concavo-convex of mutually mating, and described release bolt assembly is enclosed within guide pin bushing.
The above-mentioned parking and braking mechanism with spheric structure, wherein, described middle body is formed with middle body cavity, and described guide pin bushing to be embedded in middle body mesopore and to be slidably matched with hole wall in middle body, is provided with O RunddichtringO in described middle body.
The utility model contrast prior art has following beneficial effect: the parking and braking mechanism of what the utility model provided have spheric structure, by arranging push rod dish, epithelium, piston rod head phase-contact surface be spheric structure, thus can ensure that push rod dish, epithelium, piston rod head are face contact at any time, improve the operating conditions of epithelium, effectively extend the working life of epithelium and arrester.

Embodiment
Below in conjunction with drawings and Examples, the utility model will be further described.
Fig. 1 is the parking and braking mechanism structural representation that the utility model has spheric structure.
Refer to Fig. 1, the parking and braking mechanism of what the utility model provided have spheric structure, comprise protecgulum 8, middle body 4, piston rod 5 and push-rod assembly 9, push-rod assembly 9 is provided with between described protecgulum 8 and middle body 4, described push-rod assembly 9 is connected with break swing arm 1 by clevis 10, described piston rod 5 to be enclosed within housing assembly and to be connected with release bolt assembly, epithelium 3 is provided with between described push rod dish 2 and middle body 4, wherein, described push rod dish 2, epithelium 3 and piston rod 5 head phase-contact surface are spheric structure.
The parking and braking mechanism of what the utility model provided have spheric structure, back cavity pressurized air pressure release during parking braking, back cavity brute spring promotes piston rod 5 and moves forward, and contacts with ante-chamber epithelium 3, and drive ante-chamber epithelium 3, push rod dish 2 moves forward, push-rod assembly 9 promotes break swing arm 1 and swings, brake-toggle shaft is rotated with swing arm, drives brake shoe to open, hold brake drum tightly, stop vehicle wheel rotation, realize braking.
The parking and braking mechanism of what the utility model provided have spheric structure, described piston rod 5 is connected with middle body by guide pin bushing, described housing assembly is aluminium alloy cylinder, described aluminium alloy cylinder and middle body 4 are crimped together by concavo-convex of mutually mating, and aluminium alloy cylinder and middle body 4 are crimped more tight; Described release bolt assembly is enclosed within guide pin bushing.Described middle body 4 is formed with middle body cavity 6, described guide pin bushing to be embedded in middle body mesopore and to be slidably matched with hole wall in middle body, be provided with O RunddichtringO 7 in described middle body 4, thus avoid the issuable phenomenon coming off and leak gas in long-time using process, extend product working life.
Although the utility model discloses as above with preferred embodiment; so itself and be not used to limit the utility model; any those skilled in the art; not departing from spirit and scope of the present utility model; when doing a little amendment and perfect, therefore protection domain of the present utility model is when being as the criterion of defining with claims.
