Abstract
The utility model discloses a motorcycle racing bike brake caliper which comprises a wheel cylinder casing (1), a wheel cylinder piston (6), a brake shoe (2) and a deflating valve (8). A bidirectional double-cylinder structure is positioned between the wheel cylinder casing and the wheel cylinder piston, the upper portion of the brake shoe is arranged in a limiting groove (11) formed in the wheel cylinder casing, and the lower portion of the brake shoe is clamped in a clamping groove (12) formed in the wheel cylinder casing through a brake leaf spring (3). The motorcycle racing bike brake caliper is a bidirectional double-cylinder (four-cylinder) brake caliper and is compact in structure, strong in brake force, good in stability, long in service life and free of noise in braking. The brake shoe is convenient to replace. Furthermore, the wheel cylinder casing is high in strength, small in brake deformation, high in brake flexibility efficiency, simple and easy to dismount and adjust and easy to maintain. Thus, performance of a brake is improved, and driving safety is greatly improved.
Description
Technical field
The present invention relates to a kind of Brake for vehicle, specifically relate to a kind of motorcycle brake pincers.
Background technique
At present, people more and more like the motorcycle sport car of racing, and under the prerequisite of scientific and technological high speed development, not merely based on the demand of riding instead of walk, the competition of the fast and the furious also is that people constantly pursue to motorcycle.High-performance motorcycle sport car need to have brake calipers and its coupling of powerful braking ability, and the trickle distortion of brake calipers can have influence on the brake safe of car load in high speed scanning frequency process.Some common motorcycle brake pincers are difficult to satisfy its performance requirement now, minute pump case of its brake calipers is split type, generally adopt unidirectional single cylinder structure, single wheelcylinder piston is unidirectional to be contained in minute pump case one side, drive first the inside brake shoe plate and indirectly drive again outer brake shoe by this wheelcylinder piston, clamp brake disc generation braking force and realize braking, cause intensity and the sensitivity of brake calipers are affected to some extent.And brake shoe needs shoe plate guide rod and pilot pin when installing, and changes comparatively inconvenience of loading and unloading, has affected installation efficiency.Thereby overall performance and the travel safety of break have been affected.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, and provide a kind of braking to stablize motorcycle sport car brake calipers good, easy to loading and unloading.
Purpose of the present invention realizes by following technical solution: motorcycle sport car brake calipers, comprise a minute pump case, wheelcylinder piston, brake shoe, deflating valve, be two-way double-cylinder structure between described minute pump case and the wheelcylinder piston, the top of described brake shoe is contained in the restraining groove of minute pump case, and the bottom of described brake shoe is stuck in the draw-in groove of minute pump case by the brake block spring.
Described minute pump case is integrated type cast aluminium alloy ZL111.
After adopting structure of the present invention, this motorcycle sport car brake calipers is two-way twin-tub (four cylinders) brake calipers, and its compact structure has been saved raw material; Braking force is powerful, stable good; Long service life and at when braking noise free, brake shoe is changed convenient; And the wheel cylinder casing rigidity is high, and the braking distortion is little, and it is high to brake sensitive efficient, and loading and unloading are regulated simple and easy to do, for ease of maintenaince, thereby has improved the performance of break, has greatly improved the Security of driving.
Description of drawings
The present invention is described in further detail below in conjunction with accompanying drawing and mode of execution.
Fig. 1 is the structural representation of motorcycle sport car brake calipers of the present invention.
Fig. 2 is the worm's eye view of Fig. 1.
Fig. 3 is the A-A sectional view of Fig. 2.
Fig. 4 is the B-B sectional view of Fig. 1.
Embodiment
Referring to figs. 1 through Fig. 4 as can be known, motorcycle sport car brake calipers of the present invention, comprise minute pump case 1, wheelcylinder piston 6, brake shoe 2, deflating valve 8, (namely this wheelcylinder piston 6 is in respectively the interior both sides of minute pump case 1 for two-way double-cylinder structure between described minute pump case 1 and the wheelcylinder piston 2, two-wayly be altogether four, two wheelcylinder pistons are facing to inboard brake shoe, two wheelcylinder pistons are facing to the brake shoe in the outside in addition), the top of described brake shoe 2 (both sides have upper projection 21) is contained in the restraining groove 11 of minute pump case 1, and the bottom of described brake shoe 2 (having lower projection 22) is stuck in the draw-in groove 12 of minute pump case 1 by brake block spring 3.The brake shoe installation and maintenance are convenient.
Wherein, rectangular seal 5, dust ring 4 are housed between wheelcylinder piston 6 and minute pump case 1, deflating valve dust cap 7 is housed on the deflating valve 8; On minute pump case 1 oil-feed bolt 10 and plain cushion 9 thereof are housed also.During maintain and replace, unload the brake block spring and the restraining groove 11 interior taking-ups of brake shoe from minute pump case 1 are got final product.As shown in Figure 2, the mounting hole 13 on described minute pump case 1 is for vertically arranging installation, this mounting hole 13 be shaped as ellipticity or slotted hole shape, to make things convenient for the fine position after brake calipers is installed.
Described minute pump case 1 (being braking clamp body) be integrated type cast aluminium alloy ZL111, make that its intensity is good, weight is lighter.Minute pump case 1 (being braking clamp body) adopts two-way twin-tub, monolithic construction, the brake calipers of the unidirectional single cylinder structure of more generally using, and compact structure not only, quality is light, has saved raw material; And caliper intensity is high, exquisite appearance, and the braking distortion is little, easily seals not easy oil leakage, and heat radiation is good, long service life.
When hydraulic oil is delivered to well-behaved pump case 1 (braking clamp body by Brake hose, be equal to oil cylinder) interior two wheelcylinder pistons (totally four of both sides, all around) that promote, the brake shoe that is promoted simultaneously medial and lateral by two wheelcylinder pistons clamps brake disc, produces the braking that braking force realizes the motorcycle sport car.After the oil circuit release, the wheelcylinder piston return, the brake shoe of medial and lateral separates with brake disc under the effect of brake block spring, and the assurance sport car is normally driven a vehicle.
Claims (2)
1. motorcycle sport car brake calipers, comprise a minute pump case (1), wheelcylinder piston (6), brake shoe (2), deflating valve (8), it is characterized in that: be two-way double-cylinder structure between described minute pump case (1) and the wheelcylinder piston (6), the top of described brake shoe (2) is contained in the restraining groove (11) of a minute pump case (1), and the bottom of described brake shoe (2) is stuck in the draw-in groove (12) of a minute pump case (1) by brake block spring (3).
