Abstract

The utility model discloses a glossy pressure dish of prevention of seepage is stopped, including the dish main part of stopping, the inner chamber that the main part was stopped to the dish respectively is equipped with a brake block from top to bottom, be equipped with the bakelite piston in the one side that the brake block was kept away from mutually, bakelite piston and dish are stopped and are equipped with the retainer plate between the main part inner chamber wall, it is fixed mutually that main part inner chamber wall is stopped to retainer plate and dish, the bakelite piston is kept away from brake block one end and is equipped with the rubber circle, rubber circle both ends respectively with dish stop main part inner chamber wall, retainer plate looks butt. Set up the retainer plate between the main part inner chamber wall through stopping at bakelite piston and dish, when the bakelite piston moved with the rubber circle together, the retainer plate supported the rubber circle to make the rubber circle not stop main part inner chamber wall with the dish and break away from mutually, improved prevention of seepage oil effect.

Description

A kind of seepage-proof oil hydraulic disc brake
Technical field
The utility model relates to a kind of brake gear, particularly a kind of seepage-proof oil hydraulic disc brake.
Background technology
The hydraulic disc brake used at present, comprise disc brake main body 1, the inner chamber of disc brake main body 1 is respectively provided with a brake facing 2 up and down, brake facing 2 mutually away from one side be provided with bakelite piston 3, the rubber ring 4 abutted against with internal chamber wall is arranged with outside bakelite piston 3, as shown in Figure 1, when the oil mass in disc brake main body 1 inner chamber becomes many, promote bakelite piston 3 and make move toward one another, thus drive brake facing 2 move toward one another to play braking action, rubber ring 4 plays the effect of seepage-proof oil, but there is certain shortcoming in it: when bakelite piston 3 moves, rubber ring 4 internal chamber wall that is easy and disc brake main body 1 is separated, seepage-proof oil effect is bad, and the requirement on machining accuracy of rubber ring is higher, thus improve productive costs.
Utility model content
In order to solve above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of seepage-proof oil hydraulic disc brake, improves seepage-proof oil effect.
To achieve these goals, a kind of seepage-proof oil hydraulic disc brake designed by the utility model, comprise disc brake main body, the inner chamber of described disc brake main body is respectively provided with a brake facing up and down, described brake facing mutually away from one side be provided with bakelite piston, mounting ring is provided with between described bakelite piston and disc brake body lumen wall, described mounting ring and disc brake body lumen wall fix, described bakelite piston is provided with rubber ring away from brake facing one end, and described rubber ring two ends abut against with disc brake body lumen wall, mounting ring respectively.When oil mass increases, make the centre portion of rubber ring protruding to brake facing direction, thus promotion bakelite piston moves, bakelite piston promotes brake facing and moves, because rubber ring two ends abut against with mounting ring, disc brake body lumen wall respectively, thus rubber ring is not separated with disc brake body lumen wall, improve its seepage-proof oil effect.
A kind of fixed form of mounting ring, is locked by tooth line between described mounting ring and disc brake body lumen wall.
In order to protect rubber ring not damaged when mounted, between described rubber ring and mounting ring, be also provided with briquetting.
The seepage-proof oil effect of further raising rubber ring, described rubber ring two ends are respectively equipped with the convex hook of brake facing dorsad, described convex hook embeds in the groove of disc brake body lumen wall, when rubber ring is promoted by oil, convex hook is fixed to enclose and props up, all the time abut against with groove, ensure that good seepage-proof oil effect.
A kind of seepage-proof oil hydraulic disc brake that the utility model obtains, its technique effect is: by arranging mounting ring between bakelite piston and disc brake body lumen wall, when bakelite piston moves together with rubber ring, mounting ring props up rubber ring, thus rubber ring is not separated with disc brake body lumen wall, improve seepage-proof oil effect, and reach seepage-proof oil effect owing to being propped up rubber ring by mounting ring, the precision that rubber ring adds man-hour can be reduced, thus reduce productive costs.
Accompanying drawing explanation
Fig. 1 is the structural representation of hydraulic disc brake in prior art.
Fig. 2 is the structural representation in the utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 2, a kind of seepage-proof oil hydraulic disc brake that the utility model provides, comprise disc brake main body 1, the inner chamber of described disc brake main body 1 is respectively provided with a brake facing 2 up and down, described brake facing 2 mutually away from one side be provided with bakelite piston 3, mounting ring 5 is provided with between described bakelite piston 3 and disc brake main body 1 internal chamber wall, described mounting ring 5 is locked by tooth line with disc brake main body 1 internal chamber wall, described bakelite piston 3 is provided with rubber ring 6 away from brake facing 2 one end, the radius of described rubber ring 6 is greater than the radius of bakelite piston 3, and the two ends of described rubber ring 6 abut against with disc brake body lumen wall respectively, briquetting 7 is provided with between rubber ring 6 and mounting ring 5, thus make mounting ring 5 prop up rubber ring 6 by briquetting 7.When oil mass increases, make the centre portion of rubber ring 6 protruding to brake facing direction, thus promotion bakelite piston 3 moves, bakelite piston 3 promotes brake facing 2 and moves, because mounting ring 5 is motionless, briquetting 7 props up rubber ring 6, thus rubber ring is not separated with disc brake body lumen wall, improves its seepage-proof oil effect.
Described rubber ring 6 two ends are respectively equipped with the convex hook 8 of brake facing 2 dorsad, described convex hook 8 embeds in the groove 9 of disc brake main body 1 internal chamber wall.When this hydraulic disc brake brakes, convex hook 8 circle 5 that is fixed propped up, and abuts against all the time, improve the seepage-proof oil effect of this hydraulic disc brake with groove 9.
When assembling this hydraulic disc brake; first rubber ring 6 is put into hydraulic disc brake inner chamber; then briquetting 7 is put into; put into mounting ring 5 again; mounting ring 5 is locked by tooth line and internal chamber wall, and briquetting 7 avoids rubber ring 6 directly to contact with mounting ring 5, when mounting ring 5 is locked; rubber ring 7 can be protected not damaged, then bakelite piston 3 and brake facing 2 are installed.
The use of this hydraulic disc brake is same as the prior art, repeats no more.
