Description
Technical field
The present invention relates to a kind of brake for motorcycle, relate in particular to a kind of motor bike rear brake hydraulic brake.
Background technology
Referring to Fig. 4, Fig. 5, motor bike 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, brake pipe 3 and brake control lever 4 are installed on the drg pump housing 1, the drg pump housing 1 inside has for the piston hole 5 that piston is installed, the interior diameter D2 of piston hole 5 is 11mm, be provided with overflow weir 6 and fluid infusion hole 7 on the hole wall of piston hole 5, 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 motor bike rear brake hydraulic brake has the following disadvantages:
1, at first, existing brake band a plastics lubricating cup contain braking liquid, in the braking procedure by the downward feed flow of rubber oil hose.Because the lubricating cup of plastic material and be connected to rubber oil hose long term exposure between the drg pump housing and the lubricating cup easy aging breaking in air, the use of drg is brought potential safety hazard.Secondly, the rubber oil hose that is connected between the drg pump housing and the lubricating cup need to be occupied braking liquid, thereby increases the use amount of braking liquid.Last because lubricating cup and the drg pump housing are Split type structure, also need simultaneously rubber oil hose to connect between them, and the motor bike installing space is narrow and small, therefore also exists inconvenient shortcoming is installed.
2, because the diameter of damping hole is 0.5mm, hole depth 2.5mm, its aperture ratio is large, the liquid flow damping is large, is not easy to air emptying in the hydraulic efficiency pressure system, because air has compressibility, the impact of adversary's grip is very obvious, causes the instantaneous phenomenon that drags, and affects rider's comfort level.
Summary of the invention
The technical matters that the present invention solves is:
1, provides a kind of motor bike rear brake hydraulic brake, can improve the safety of braking, be convenient to simultaneously installation and maintenance, can also promote the overall aesthetics after motor bike is installed this drg.
2, provide a kind of motor bike rear brake hydraulic brake, avoid drg phenomenon in use to occur dragging, improve the traveling comfort of operation.
Technical scheme of the present invention is: a kind of motor bike rear brake hydraulic brake, comprise the drg pump housing and lubricating cup, on the described drg pump housing brake pipe and brake control lever are installed, the drg pump body has for the piston hole that piston is installed, be provided with overflow weir and fluid infusion hole on the hole wall of described piston hole, the bottom in described fluid infusion hole is provided with damping hole, the fluid infusion hole is communicated with described piston hole by described damping hole, described lubricating cup is arranged on the described drg pump housing and is one-body molded with the described drg pump housing, be provided with the oil transportation road in the hole wall of described piston hole, described overflow weir all is 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, since lubricating cup of the present invention be arranged on the described drg pump housing and be one-body molded with the described drg pump housing, be provided with the oil transportation road in the hole wall of described piston hole, described overflow weir all is 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 and the drg pump housing, cancellation is existing for the rubber oil hose between lubricating cup in the prior art and the drg pump housing, avoid on the one hand the shortcoming that lubricating cup employing plastics easily wear out in the prior art, rubber oil hose easily wears out, improved the safety that drg uses; Owing to having cancelled rubber oil hose, can reduce the use of braking liquid on the other hand, save use cost; And because the drg pump housing and lubricating cup are one-body molded, cancelled the rubber oil hose between lubricating cup of the prior art and the drg pump housing, reduced installing space, so that the structure of drg is compacter, be convenient to installation and maintenance, can also promote the overall aesthetics after motor bike is installed this drg.
2, the aperture ratio of existing drg damping hole is large, and the liquid flow damping is large, is not easy to air emptying in the hydraulic efficiency pressure system, because air has compressibility, the impact of adversary's grip is very obvious.The contriver is by having carried out analysis and measurement to the drg pump housing, the damping hole place belongs to meiobar, intensity is not required, root a tree name liquid stream flow principles, damping hole to bottom, fluid infusion hole redesigns the diameter D1=0.6mm of damping hole, length L=1mm, thereby can avoid drg phenomenon in use to occur dragging, improve the traveling comfort of operation.
