Abstract

The utility model discloses an improved piston structure of a motorcycle brake, comprising a fixed bracket, a calipers piston, a heat insulator and a brake pad; the fixed bracket forms an accommodation cavity, and the calipers piston is embedded in the accommodation cavity; the brake pad is arranged on the fixed bracket by pins and is over against the calipers piston; and the calipers piston forms an axial groove, and the heat insulator is arranged in the axial groove and leans against the brake pad. The improved piston structure can be used to effectively prevent the heat generated by the friction of the brake pad and a disc from being transferred to the brake fluid, and further, the structure is simple.

Description

A kind of piston of motorcycle brake break improves structure

Technical field

The utility model relates to a kind of motorcycle brake break, and the piston that refers in particular to a kind of motorcycle brake break improves structure.

Background technique

The use of motorcycle is very general; Especially use generally especially in the rural area, and brake device is to the important effect that plays safe in utilization of motorcycle, and motorcycle brake break of the prior art is generally disc brake; This disc brake is striden the both sides of being located at wheel central authorities brake disc; Disc brake can be divided into floating type and fixed again, and wherein fixed disc brake comprises cylinder body, total pump piston, brake-fluid pipe, clamp piston and brake block, and total pump piston is slidingly installed with in cylinder body; The clamp piston also is installed in the cylinder body, and links to each other with total pump piston through the brake-fluid pipe; The brake block pin is located on the cylinder body, and with the clamp piston over against.During use, total pump piston moves, and compresses brake-fluid and is transferred to the clamp piston through the brake-fluid pipe, and the clamp piston promotes brake block and presses to disc, brakes.

Like Fig. 1 and shown in Figure 2, in the existing technology, the piston structure of motorcycle brake break; Comprise clamp piston 20, brake block 30 and fixed support 40; Fixed support 40 is crossed on wheel disc both sides, forms holding cavity 401 on the fixed support 40, and clamp piston 20 embeds in the holding cavity 401 of fixed support 40; Brake block 30 pins are located on the fixed support 40, and over against clamp piston 20.This shows that in the existing technology, clamp piston 20 directly contacts with brake block 30, in when brake, friction generates heat with disc for brake block 30, and wherein the part heat passes through brake block 30 and passes to clamp piston 20, conducts to brake-fluid by clamp piston 20 again.Therefore, in the existing technology, the piston structure of motorcycle brake break has following defective:

One, when motorcycle brakes a period of time in the process of moving continuously, produces a large amount of heats, because the clamp piston is made of metal; Heat is transmitted fast; Heat is delivered to brake-fluid very soon, causes the temperature of brake-fluid too high, even vaporization; Thereby cause the soft partially or brake inefficacy of brake, and then cause danger.

Two, the brake-fluid temperature is too high, and brake-fluid itself is oxidized easily, thereby makes the performance change of brake-fluid.

Seeing that the above-mentioned defective of the piston structure of motorcycle brake break in the existing technology, the inventor develops a kind of piston that overcomes the motorcycle brake break of above-mentioned defective and improves structure, and this case produces thus.

The model utility content

The purpose of the utility model is to provide a kind of effective blocking-up heat to transmit, and the piston of motorcycle brake break simple in structure improves structure.

For reaching above-mentioned purpose, the solution of the utility model is:

A kind of piston of motorcycle brake break improves structure, comprises fixed support, clamp piston, insulator and brake block; Fixed support forms holding cavity, and the clamp piston embeds in the holding cavity; The brake block pin is located on the fixed support, and over against the clamp piston; Form axial notch on the clamp piston, insulator places axial notch, and with brake block against.

After adopting such scheme; The utility model is provided with insulator between clamp piston and brake block, when the fricative a large amount of heat of brake block and disc, insulator cuts off heat and blocks its conduction and give brake oil; Thereby guarantee the normal performance of brake oil, ensure the traffic safety of motorcycle.Therefore, the utility model compared with prior art has the following advantages:

Even one, the utility model makes brake continue brake a period of time, still can make the temperature of brake-fluid keep normal, thereby make the brake device proper functioning of motorcycle;

Two, the utility model makes brake-fluid can keep normal temperature, thereby guarantees the performance of brake-fluid, reduces the replacing number of times of brake-fluid, thereby practices thrift user cost.

Embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is done detailed explanation.

Consult Fig. 3 to shown in Figure 5, the piston of a kind of motorcycle brake break that the utility model discloses improves structure, comprises insulator 1, clamp piston 2, brake block 3 and fixed support 4.

Fixed support 4 forms holding cavity 41, and clamp piston 2 embeds in the holding cavity 41; Brake block 3 pins are located on the fixed support 4, and over against clamp piston 2; Form axial notch 21 on the clamp piston 2, insulator 1 places axial notch 21, and with brake block 3 against.

Said insulator 1 can be selected insulator commonly used in the existing technology for use.

The utility model is after continuing brake a period of time; Friction-produced great amount of heat between brake block 3 and the disc (not shown); Owing between brake block 3 and clamp piston 2, be provided with insulator 1, thereby heat stopped and be unlikely to give brake-fluid that the temperature of brake-fluid can be not too high because of the temperature that continues to brake through 2 conduction of clamp piston; Even vaporization, and then cause the soft partially even brake inefficacy of brake.The Security of using the utility model can improve the motorcycle brake break, the replacing number of times that also can reduce brake-fluid is to practice thrift cost.

The key improvements part of the utility model is, between clamp piston 2 and brake block 3, be provided with insulator 1, and other member of motorcycle brake break all is an existing technology, does not give unnecessary details here.

The embodiment that the above is merely the utility model is not the restriction to this case design, and all equivalent variations of doing according to the design key of this case all fall into the protection domain of this case.
