Description
Technical field
The utility model is related to motorcycle machine components technical field, is concretely related to a kind of motorcycle brake clamp and lives
Plug.
Background technology
Motorcycle, is driven by gasoline engine, and by the two-wheeled or tricycle of bar handle front-wheel steer, light and flexible is travelled fast
Speed, is widely used in patrol, passenger and freight transportation etc., also serves as sports movement apparatus.For from big direction, motorcycle is divided into street
Car, racing cycle motorcycle, cross country motorcycle, cruise car, station wagon etc..
The brake system of motorcycle, be otherwise known as " brakes ", and effect is the effect for pining down power, is motor cycle rider's
One safeguards system of safety, a very important security system.General brake system is divided into two ways, and one kind is depreciation tendency
Brake, one kind is hub brake.
Disc brake：The brake fluid in pressure promotion brake oil pipe is produced by upper pump in braking, brake fluid again will brake
Piston in the lower pump brake callipers that namely we are commonly called as is released, and piston press brake block rubs by brake block and brake disc and produced
Raw brake force.
Hub is braked：It is then the brake shoe in brake line control wheel hub, is connect with the hub in wheel hub after brake shoe spreading
Touch wiping and produce brake force.
The disc brake that compares is braked better than hub, but disc brake loss is larger, changes and maintain more complicated, in brake
Oil again releases the piston in brake callipers, and piston press brake block produces brake force by brake block and brake disc friction, existing
Frictional force is smaller when piston is contacted with brake block in technology, easily skids, and influence braking effect is poor, while piston and braking clamp
Air inconvenience in cramp joint tactile space is excluded, and is squeezed the air in attaching space, is caused braking effect poor.
Utility model content
Therefore the utility model proposes a kind of motorcycle brake caliper piston, for solving piston in the prior art and brake
Frictional force is smaller when piece is contacted, and easily skids, and influence braking effect is poor, while piston and the sky in brake caliper attaching space
Gas inconvenience is excluded, and is squeezed the air in attaching space, is caused the problem of braking effect is poor.
What the technical solution of the utility model was realized in：A kind of motorcycle brake caliper piston, including piston only,
The embossing of round is provided with end face and plunger shaft, the end face, the embossing is arranged on the outer ring of end face, the embossing
Longitudinal section is trapezoidal and set in emitting shape, described convex in being provided with several boss on end face on the inside of the embossing of the round
The upper surface of platform sets several double wedges, and the height of the double wedge is equal to the height of embossing；Described one end close to plunger shaft in
Seal groove is provided with piston only, the trapezoidal and trapezoidal top in the longitudinal section of the seal groove is the opening of seal groove；Institute
State plunger shaft and be disposed with the first land and the second land, the diameter of first land and the second land increases successively.
Using the utility model of such scheme, piston pass through the double wedge on end face in the embossing and several boss of round come
Brake block is extruded, frictional force when piston is contacted with brake block is enhanced, makes it be difficult to skid, while piston is contacted with brake caliper
Air in space can be excluded smoothly from the gap between embossing, ensured the security of the brake system of motorcycle, fitted
Close enterprise and promote production.
Further, the quantity of the boss is five, and five boss are surrounded in end face center one, remaining four
Center constitutes the distribution of square.
Further, the double wedge quantity of the upper surface of the boss is 12 and is mutually 30 ° and is uniformly distributed.
Further, the embossing, boss, double wedge, plunger shaft, the first land, the second land and seal groove be and piston
Body integrally casting shaping.
By above disclosure, the beneficial effects of the utility model are：The motorcycle brake caliper piston compact conformation,
Frictional force is larger when piston is contacted with brake block, is difficult to skid, while the air in piston and brake caliper attaching space can be with
Smoothly excluded from the gap between embossing, ensured the security of the brake system of motorcycle.
