Abstract

The utility model relates to an improved structure of an oil pressure brake for bicycles. A brake grip is connected and extended with a brake conducting wire until a brake, and the brake conducting wire is erected and connected with a dish type brake disk through the brake which is an oil pressure cylinder body in an irregular shape. The oil pressure cylinder body is formed by the abutment combination of two half symmetrical pressure cylinder bodies; each pressure cylinder body is provided with an oil inlet; three pressure cylinder grooves with different calibers and volumes are arranged on a main body; each pressure cylinder groove is respectively hold with pistons with well matched size; each piston is hooped with an oil seal and the front ends of two of the pistons are sucked with magnets. When the pistons actuates, the oil seals can be used for heat radiation, and the magnets can be used for sucking a brake sheet of the dish type brake disk of an original brake to the original position to wait for the next brake actuation.

Description

The structural improvement of bicycle oil pressure brake

The structural improvement of a kind of bicycle oil pressure of the utility model brake is relevant with the brake component structure, more detailed it, refer to the structural improvement of the bicycle oil pressure brake of the convenient and safety raising of a kind of assembling especially.Belong to bicycle brake device.

The Regular Bicycle brake has more advanced hydraulic type brake except that the traditional type brake at present, and cooperates the disc brakes dish to use, and sees also Figure 1 and Figure 2, yet the following points drawback appears in this structure regular meeting when implementing:

1, during emergency brake, locked easily, cause overturn dangerous.

2, the temperature of the inner brake of brake back is too high, and heat radiation is slow again, often causes shorten service life.

3, brake facing is generally irony, thinner, and is excessive with the brake disc friction force, and easy deformation, influence brake sensitivity.

The purpose of this utility model is: a kind of structural improvement of bicycle oil pressure brake is provided, and its assembling is convenient and safety is higher, and the value of industrial community utilization can be provided, and makes it to have more economic benefit.

The structural improvement of a kind of bicycle oil pressure of the utility model brake, it is to be linked by Brake lever to extend Brake cable until brake, and be located on the disc brakes dish by brake construction company, it is characterized in that: this brake system is an irregularly shaped oil-hydraulic cylinder, and by two half of symmetrical cylinder pressure bodies mutually by being combined into one, wherein, this cylinder pressure system is provided with an oil inlet, and on body, establish the cylinder pressure groove of three bores and volume difference, the then ccontaining respectively piston that matches size of each cylinder pressure groove, and on piston hoop bundle have oil sealing and wherein two piston nose inhale and establish a magnet, but mat oil sealing heat radiation and utilize magnet that the brake facing of former brake disc formula brake disc is sucked back the original place during for the piston start, and treat next braking action.

The utility model has the advantages that:

1, gradual brake prevents lockedly, and can improve safety.

2, easy to assembly and convenient rapidly, efficient improves.

3, brake is sensitive and smooth and easy, feels at ease when the customer operates.

4, oil sealing design attitude increases radiating rate, and can increase brake service life.

5, brake facing is made by aluminum alloy, and is thicker and area is big, is not easy distortion, and braking action is highly stable.

The utlity model has following accompanying drawing:

Figure 1A, B are for commonly using the schematic perspective view of brake.

Fig. 2 is for commonly using the combination cross-sectional schematic of brake.

Now lift preferred embodiment and conjunction with figs. is described as follows:

At first, see also Fig. 3 to shown in Figure 6, the structural improvement of a kind of bicycle oil pressure of the utility model brake, it is to be linked by Brake lever to extend Brake cable 10 until brake 20, and is located on the disc brakes dish 30, wherein by brake 20 construction companys:

This brake 20 is to be an irregularly shaped oil-hydraulic cylinder, and by two half of symmetrical cylinder pressure bodies 21 mutually by being combined into one, wherein, this cylinder pressure body 21 is that an oil inlet 211 is set, and on body, establish the cylinder pressure groove 22 of three bores and volume difference, 23,24 (arranging) by little extremely different bore, and each cylinder pressure groove 22,23,24 ccontaining respectively pistons 221 that match size, 231,241, and at piston 221,231, the hoop bundle has oil sealing 222 on 241,232,242 and wherein two pistons 231,241 front ends are inhaled and are established a magnet 233,243, but mat oil sealing 222 during for the piston start, 232,242 heat radiations and utilize magnet 233,243 brake facings 25 with former brake disc formula brake disc 30 suck back the original place, and treat next braking action.

When assembling, please continue to consult Fig. 3 to shown in Figure 6, at first, system is placed in this piston 221,231,241 in the cylinder pressure groove 22,23,24 of each cooperation in the assembling of the utility model, and these piston 221,231,241 back segment bodies bind round bundle oil sealing 222,232,242 on one's body, and bigger piston wherein 231,241 sets up two limits separately, its top is connected with magnet 233,243, and the periphery covers by this brake facing 25 again, and start by this.

When the operation start, see also Fig. 5 to Fig. 7 and cooperate Fig. 3, shown in Figure 4, at first, when running into the emergency brake, the brake 20 of the utility model can flow into brake solution to this cylinder pressure body 21 by Brake cable 10, and flow into cylinder pressure groove 22 respectively, 23,24, and this cylinder pressure groove 22,23,24 because of the volume difference, therefore respectively overflow asynchronism(-nization), promptly, the cylinder pressure groove 22 of minimum is full earlier, and secondly another cylinder pressure groove 23 and maximum cylinder pressure groove 24 are full again, and so the main system of action produces gradual brake, promptly, after the cylinder pressure groove 22 of this minimum is full earlier then start compress brake facing 25 and stop to brake disc 30, and and then respectively by other two cylinder pressure grooves 23,24 stop respectively to, so, promptly produce the incremental flowing mode of doing, it is locked that this brake modes not only reduces brake, the danger that car body skids and stands up in the time of more can preventing to brake, and safety improves more;

And after brake is finished, only move back the handle that gets off the brakes, so, brake solution in this cylinder pressure groove 23,24 refluxes automatically, and adsorb these brake facings 25 by these big cylinder pressure groove 22,23,24 inner carriers 231,241 set magnet 233,243 at this moment, make it reply originally not normal danger, and wait for next braking action.

What deserves to be mentioned is, the gradual brake design of the utility model, except that safer structure can be provided, the design of these oil sealing 222,232,242 positions more provides temperature controllable, avoids internal temperature too high, and thermolysis is provided, increase service life, because then can increase friction and make temperature higher if be arranged at front end, the high temperature that produces when making start originally more improves, and destroys the life-span of element.
