Abstract
The utility model (internal capsule type hydraulic braking device for bicycles (motorcycles)) belongs to an accessory design for bicycles (motorbikes). The power source of the utility model comprises an oil cylinder, a brake handle, connecting rods, and piston compression oil liquid on handle bars. The hollow plastic balls in an oil cup and a hollow cavity are auto exhaustion, and are used for replenishing oil liquid for oil circuit. The proofed internal capsule is expansive owing to the increased oil liquid which is pressed by the oil cylinder, pushes the piston head lock husk forward to force application on brake blocks which are fixed on brake cases and hubs, and therefore, generates brake force, to reach the arresting purpose.
Description
The invention belongs to a kind of attachment design of bicycle (motor bike).
Each cyclist wishes to have easy to use, flexible a, deceleration and stopping performance, effective, simple in structure, does not need the brake of often adjusting.Existing brake kind is a lot, but all braking effect is bad, and chief reason one is that braking force is little, and two area of contact are little.Hydraulic brake is also arranged, but the unit pressure height abroad, make complicated, accurate, cost an arm and a leg, and have a series of parts in addition of brake disc to seem heavy, use also not extensive.
Purpose of the present invention is will design a kind of making simply, good braking effect, light, attractive in appearance, rising, practical new brake system.
The present invention mainly becomes propulsion source with oil cylinder, brake lever, connecting rod, the oil cylinder piston compressing fluid that is fixed on the handlebar.Hollow in lubricating cup and the cavity is moulded ball, is the fluid in self-bleeding and the additional oil circuit.Annular glue system capsula interna is placed in the circular groove and annular piston of reaction plate,, increases when expanding because oil cylinder is pressed the fluid of coming when capsula interna, pushes the annular brake rubber block on the piston, forces in the brake facing that is fixed on lock shell and the axle skin forward, thereby produces braking force.And the U-lag on front fork fixed block and the reaction plate then overcomes lock, the torque between fork.Its principle of work is as follows: when to brake lever (1) (A) the end application of force, (B) end is a central motion around bolt (2).Drivening rod (3) pushes piston (4) in oil cylinder (5), and compressing liquid travels forward, and liquid is extruded from the hydraulic fluid port of the end cap (25) that has hydraulic fluid port.Enter in the capsula interna (8) by oil pipe (6) and capsula interna mouthpiece (7).Because the liquid that comes from oil cylinder and the increase of pressure are expanded capsula interna, then piston (9) and the brake rubber block (10) fixed on it travel forward, and the top is to brake facing (11), thus the generation braking force.When brake off, loosen brake lever, piston makes piston and brake rubber block return under the effect of four springs (12).By locating piece (27) location that is fixed on the cylinder body, it is interior along on (C) that brake rubber block is enclosed within piston tip, and by four bolt of rear end plates (13) location, simultaneously, bolt of rear end plate also plays the fixing spring effect.Radially projection (D) is at glancing impact along (19) four axial projections of reaction plate (E) rising ， And and piston tip for piston, and mutual action overcomes the inside torque that is produced by braking.Directional tagging when simultaneously, also playing piston motion.Brake facing is fixed on the skin (15) with lock shell (16) together by screw (14), the brake facing effect: one and brake rubber block play the increase friction force, another and lock shell bear the axial force of glancing impact together.There is being the U-lag (18) on a fixed block (17) and the reaction plate to match on the front fork, to remove the relative torque of lock body and front fork glancing impact.There is a hydraulic fluid port oil cylinder front end top, is with lubricating cup (26) outward, on the enclosing cover (21) of band pore (20) is arranged.In the cavity that between hydraulic fluid port and lubricating cup, forms (23), the baton round (23) of the hollow that floats.Effect is: when air occurring in oil circuit or the oil cylinder, air can on float in the cavity, reduce equally with fluid, the come-up bead has downswing, storage fluid can enter in the chamber from the seam that the decline bead lightens immediately in the cup, bead floats again, the dieback through hole.Thereby realize self-bleeding and additional fluid.Simultaneously, when the brake lever application of force, because bead dieback through hole so fluid is unlikely to eject, forms pressure.There is a filtering net (24) top in the cup, is that foul enters when preventing oiling.The pore that covers outward can normal operation be established for guaranteeing oil circuit.
Because wheel braking partly adopts sealant system capsula interna, area of contact is big, and unit pressure is low, leaks atomicly, needn't adopt high strength material, accurate sealing and processing, but also can use water as medium.Therefore, simple for production, cost is low, in light weight, braking force is big, is better than external hydraulic brake.More be better than other type lock.Because this structure adopts axially braking, also be convenient to use the multi-disc braking of bicycle, motor bike and the development of disengaging type braking aspect.Basic bicycle, the ineffective problem of motorcycle brake of solving.Drawing of the present invention is described as follows:
