Abstract
The utility model provides a disc brake which comprises a brake disc, a main pump component, a sub-pump component and a brake piece, wherein an oil pipe is connected between the main pump component and the sub-pump component. The sub-pump component is composed of a pump shell, a cavity is arranged in the pump shell, and a piston is arranged in the cavity. The disc brake is characterized in that a dustproof ring is arranged between the piston and the cavity, a first ring groove is formed in the side wall of the cavity, and the dustproof ring is arranged in the first ring groove in an embedded mode. By the technical scheme, the disc brake is good in sealing effect, and capable of well preventing dust from entering into the cavity, and ensures stable working performance of a brake.
Description
Technical field
The utility model relates to the vehicle accessory field, particularly a kind of disk type braker.
Background technique
Existing a kind of disk type braker, include brake disc, main pump assembly, wheel cylinder assembly, braking plate, be connected through oil pipe between described main pump assembly and the wheel cylinder assembly, wherein, described wheel cylinder assembly includes pump case, be provided with cavity in the pump case, be provided with piston in the described cavity, braking plate is arranged on the cavity opening, when braking, fluid is in oil pipe enters into cavity, and pushing piston is realized braking so that braking plate and brake disc are conflicted.But, the disc type brake dish of this structure, some dusts can enter into cavity, cause break in braking process, and pistons work is insensitive, thereby affects the braking effect of break.
Summary of the invention
The purpose of this utility model: in order to overcome the defective of prior art, the utility model provides a kind of disk type braker, and its good sealing effect can prevent well that dust from entering into cavity, thereby guarantees the break stable work in work.
The technical solution of the utility model: a kind of disk type braker, include brake disc, main pump assembly, wheel cylinder assembly, braking plate, be connected through oil pipe between described main pump assembly and the wheel cylinder assembly, wherein, described wheel cylinder assembly includes pump case, is provided with cavity in the pump case, be provided with piston in the described cavity, it is characterized in that: be provided with dust ring between described piston and the cavity, described cavity side walls is provided with the first ring connected in star, and described dust ring is embedded in described first ring connected in star.
Adopt technique scheme, by the dust ring that arranges between piston and cavity, so that disk type braker, good sealing effect can prevent well that dust from entering into cavity, thereby guarantees the break stable work in work; The first ring connected in star that arranges is so that the location of dust ring is firm.
Further setting of the present utility model: also be provided with seal ring between described piston and the cavity, described seal ring is positioned at the dust ring inboard, and described cavity side walls is provided with the second annular groove, and described seal ring is embedded in described the second annular groove.
Adopt above-mentioned further setting, the seal ring of setting can prevent that fluid from leaking from cavity, and then causes break work insensitive, and the poor phenomenon of braking effect occurs.
Again further setting of the present utility model: described oil pipe is provided with mounting plate, and described mounting plate is provided with supporting foot, is provided with stiffening rib between described supporting foot and the mounting plate.
Adopt above-mentioned more further setting, the supporting foot that arranges on the mounting plate of setting, the mounting plate can conveniently position oil pipe; The stiffening rib that arranges between supporting foot and mounting plate can be so that more firm between mounting plate and the supporting foot.
