Description
Technical field
This utility model relates to a kind of bicycle accessories, the bicycle disc brake device of especially a kind of improvement.
Background technology
Bicycle is that the trip that the our people masses commonly use is ridden equipment.Present stage, the brake system of bicycle mainly has traditional friction pulley frame brake system and disk type braking system.Disc brake mainly connects metal disc at coaxial group of the colored hub of wheels, is separately provided with to clip the disk brake caliper of disc in bicycle front fork or back vent near flower hub position, slows down disc rotation also with frictional force or stop operating.Disc brake system receives increasing application by feat of its superior braking quality.Chinese utility model patent CN204096013U discloses a kind of mechanical disc brake, solves disc brake braking strength and discharges too fast too quickly problem, it is achieved that the brake feel of multistage.But, the disc brake of this structure is multistage for the release of braking strength, can cause the ladder hopping sense of braking strength in brake process, causes that the release of braking strength is uneven.
Utility model content
The technical problems to be solved in the utility model is to provide the bicycle disc brake device of a kind of improvement, it is possible to solve the deficiencies in the prior art, improves the uniformity of disc brake system braking strength release.
For solving above-mentioned technical problem, technical solution adopted in the utility model is as follows.
A kind of bicycle disc brake device of improvement, including two symmetrically arranged braking mechanisms, braking mechanism includes rocking arm; rocking arm is connected to cam disc; cam disc drives piston to be pressed against on brake block; be provided with buffer part between described cam disc and piston; buffer part includes the first spring body; be provided with hydraulic stem in the first spring body; hydraulic stem is connected to hydraulic cushion tank by conduit; the junction of hydraulic cushion tank and conduit is provided with reducing, is provided with piston layer in hydraulic cushion tank, and piston layer is connected to the bottom of hydraulic cushion tank by the second spring body；Being fixed with support bar on brake block, the top of support bar is provided with lock groove, and support bar runs through piston, and the surface configuration of cam disc has the blind hole matched with support bar, is provided with and the locking slide block of lock groove selectivity clamping in blind hole.
As preferably, described reducing place is provided with adjusting rod, and adjusting rod is threadeded with reducing, and the top of adjusting rod is fixed with sheet rubber, and the top of sheet rubber is flexibly connected with the inwall of reducing by connecting axle, and the sidewall of sheet rubber is provided with several the first through holes.
As preferably, being evenly arranged with several the second through holes on described brake block, the second through hole is perpendicular to brake block and arranges, and the inwall of the second through hole is provided with annular groove, being provided with the first guiding gutter between two the second adjacent through holes, the two ends of the first guiding gutter are connected with annular groove.
What employing technique scheme was brought has the beneficial effects that: this utility model, by arranging hydraulic stem, utilizes the reciprocal flowing of hydraulic oil between hydraulic stem and hydraulic cushion tank, it is achieved the buffering of braking strength and homogenizing.Hydraulic oil is when flowing through reducing, bigger resistance can be subject to, this can ensure that the time delay of hydraulic stem is stretched, thus when realizing the brake of large force degree, hydraulic oil in hydraulic stem is owing to being subject to the resistance of reducing, so that hydraulic stem can keep higher intrinsic pressure in the starting stage of brake, realize the rapid release of braking strength, posterior segment at brake process, along with hydraulic oil gradually passes through reducing, the intrinsic pressure of hydraulic stem is gradually lowered so that braking strength slowly reduces, thus avoiding the release of disc brake system braking strength too fast too quickly；During the brake of low-force degree, hydraulic oil has relatively plenty of time and passes through reducing so that the intrinsic pressure of hydraulic stem will not increase sharply, it is achieved the mild release of whole braking strength.When needs rapidly discharge whole braking strength, being pressed against completely on brake block by piston, support bar stretches in blind hole, locking slide block and lock groove clamping locking, it is achieved the hard link of brake system so that braking strength all discharges.By changing the position of adjusting rod, it is possible to the elastic deformation of sheet rubber, thus changing the reducing resistance for running of hydraulic power oil, it is achieved for the flexible adjustment of brake system braking strength.Along with the use of brake system, brake system there will be heat fade.The radiating effect of the heat abstractor on tradition disc brake sheet is uneven, and the position radiating effect away from louvre is not good.The second through hole designed by this utility model coordinates with guiding gutter, it is possible to achieve the Uniform Flow of disc surface air-flow, improves the uniformity of brake block heat radiation, reduces the heat fade of brake system.
