Description
Technical field
The present invention relates to a kind of brake for motorcycle, particularly relate to a kind of Motorcycle rear brake hydraulic brake.
Background technology
See Fig. 4, Fig. 5, Motorcycle rear brake hydraulic brake comprises the drg pump housing 1 and lubricating cup 2, the material of lubricating cup 2 is plastics, lubricating cup 2 is connected with the drg pump housing 1 by rubber oil hose 11, the drg pump housing 1 is provided with brake pipe 3 and brake control lever 4, the drg pump housing 1 inside has the piston hole 5 for installing piston, the interior diameter D2 of piston hole 5 is 11mm, the hole wall of piston hole 5 is provided with overflow weir 6 and fluid infusion hole 7, the bottom in fluid infusion hole 7 is provided with damping hole, damping hole is communicated with piston hole 5, and the diameter of damping hole is 0.5mm, and the length of damping hole is 2.5mm.Existing Motorcycle rear brake hydraulic brake has the following disadvantages:
1, first, existing brake band plastics lubricating cup contains braking liquid, by rubber oil hose downward feed flow in braking procedure.Because the lubricating cup of plastic material and the rubber oil hose be connected between the drg pump housing and lubricating cup are chronically exposed to easily aging in air breaking, potential safety hazard is brought to the use of drg.Secondly, the rubber oil hose be connected between the drg pump housing and lubricating cup needs to occupy braking liquid, thus increases the use amount of braking liquid.Finally because lubricating cup and the drg pump housing are Split type structure, also need rubber oil hose to connect between them, and motor bike installing space is narrow and small simultaneously, therefore also exists and inconvenient shortcoming is installed.
2, because the diameter of damping hole is 0.5mm, hole depth 2.5mm, its aperture is than large, liquid flow damping is large, is not easy to air emptying in hydraulic efficiency pressure system, because air has compressibility, the impact of opponent's grip clearly, causes instantaneously dragging phenomenon, affects the comfort level of rider.
Summary of the invention
The technical matters that the present invention solves is:
1, provide a kind of Motorcycle rear brake hydraulic brake, the safety of braking can be improved, be convenient to installation and maintenance simultaneously, can also promote motor bike this drg is installed after overall aesthetics.
2, provide a kind of Motorcycle rear brake hydraulic brake, avoid drg in use to occur dragging phenomenon, improve the traveling comfort of operation.
Technical scheme of the present invention is: a kind of Motorcycle rear brake hydraulic brake, comprise the drg pump housing and lubricating cup, the described drg pump housing is provided with brake pipe and brake control lever, drg pump body has the piston hole for installing piston, the hole wall of described piston hole is provided with overflow weir and fluid infusion hole, the bottom in described fluid infusion hole is provided with damping hole, fluid infusion hole is communicated with described piston hole by described damping hole, described lubricating cup to be arranged on the described drg pump housing and one-body molded with the described drg pump housing, oil transportation road is provided with in the hole wall of described piston hole, described overflow weir is all communicated with described lubricating cup by described oil transportation road with described fluid infusion hole.
Described damping hole is cylindrical hole, and the diameter of damping hole is D1, and the length of damping hole is L, D1: L=3: 5.
The diameter D1=0.6mm of damping hole, length L=1mm.
The diameter D2=12.7mm of described piston hole.
The invention has the beneficial effects as follows:
1, because lubricating cup of the present invention is arranged on the described drg pump housing and one-body molded with the described drg pump housing, oil transportation road is provided with in the hole wall of described piston hole, described overflow weir is all communicated with described lubricating cup by described oil transportation road with described fluid infusion hole, realize being communicated with by described oil transportation road between lubricating cup with the drg pump housing, cancel existing for lubricating cup in prior art and the rubber oil hose between the drg pump housing, avoid on the one hand lubricating cup in prior art and adopt plastics easily aging, shortcoming that rubber oil hose is easily aging, improve the safety that drg uses; On the other hand owing to eliminating rubber oil hose, the use of braking liquid can be reduced, saved use cost; And due to the drg pump housing and lubricating cup one-body molded, eliminate the rubber oil hose between lubricating cup of the prior art and the drg pump housing, reduce installing space, make the structure of drg compacter, be convenient to installation and maintenance, can also promote motor bike this drg is installed after overall aesthetics.
2, the aperture of existing drg damping hole is than large, and liquid flow damping is large, is not easy to air emptying in hydraulic efficiency pressure system, and because air has compressibility, the impact of opponent's grip clearly.Contriver is by having carried out analysis and measurement to the drg pump housing, genus meiobar, damping hole place, to intensity not requirement, root Ju fluid flow principle, damping hole bottom fluid infusion hole is redesigned, the diameter D1=0.6mm of damping hole, length L=1mm, thus drg can be avoided in use to occur dragging phenomenon, improve the traveling comfort of operation.
