Abstract

The utility model relates to a hydraulic plate type brake as a brake for a motorcycle. The hydraulic plate type brake comprises a pump body (1), a piston cavity (2), a piston assembly (3) and a brake shoe (4). The utility model is characterized in that one side of a non braking face of the brake shoe (4) is provided with a contact point (5) and a lead wire (6) in an embedding mode. The contact point is made up by a metal block. The contact point (5) is mutually insulated with metal parts of the hydraulic plate type brake. When the hydraulic plate type brake is used, the contact point (5) is communicated with an accumulator cell, a power supply of an audible and visual alarm, and a metal machine frame of a motor vehicle in electric series connection. When the brake shoe is worn in the extreme, the contact point (5) is in contact with a metal brake disc. The power supply forms a loop. The accumulator cell provides a power supply for the audible and visual alarm. A warning indicator starts working and prompts alarms to remind to replace the brake shoe. The utility model plays safety warning function.

Description

Hydraulic brake

Technical field

The utility model relates to a kind of hydraulic brake as the motorcycle brake device.

Background technique

To bicycler's the life and the safety of property, therefore require very reliable as the security relationship of the hydraulic brake of motorcycle brake device.The hydraulic brake that circulates on market does not at present have brake shoe wear-out life limiting alarm device, in the long-term using process, brake shoe may wear to the limit, in time do not obtain finding, can cause brake to be lost efficacy or the long not return of piston stroke and cause phenomenon such as locking, bring great life potential safety hazard to the driver.

Summary of the invention

This practical purpose is to provide a kind of hydraulic brake that can timely reminding user to replace brake shoe when the break brake shoe may wear to the brake limit for the defective that overcomes prior art.

For achieving the above object, the utility model reaches by following technical solution: hydraulic brake, the brake shoe that comprises the pump housing, piston cavity, piston assembly and pair of opposing, brake shoe and piston assembly interlock, it is characterized in that: non-braking surface one side of described brake shoe is embedded with contact and lead-in wire, contact and the hydraulic brake metal parts mutually insulated that slug constitutes.

The utility model good effect compared with prior art is: owing to adopted present design, during use, be connected in series connection with contact and storage battery, audible-visual annunciator power supply and motorcycle metal machine frame on being arranged on motorcycle are electric, when brake shoe may wear to the limit, this moment, the contact contacted with the metallic brake disc, make the audible-visual annunciator power supply constitute the loop, storage battery provides power supply for audible-visual annunciator, the indication of reporting to the police is started working, prompting is reported to the police, the prompting changing brake shoe plays the safety warning effect.

Below in conjunction with accompanying drawing the utility model is described further.

Description of drawings

Fig. 1 is the structure cross-sectional schematic of the utility model specific embodiment;

Embodiment

As shown in Figure 1, hydraulic brake, still comprise the pump housing 1, piston cavity 2, piston assembly 3 and a pair of brake shoe 4, wherein a slice is fixedly installed on the pump housing 1, another sheet and piston assembly 3 interlocks, a pair of brake shoe 4 will be oppositely arranged, non-braking surface one side is embedded with the contact 5 of slug formation and goes between 6 on the brake shoe 4 that fixedly installs, the metal of good conductivity is adopted in contact 5, make column contact 5 as copper rod, as cylindrical or square column type, front end preferably is provided with flange, tail end is provided with lead-in wire 6, the outside of contact 5 is surrounded by an insulating bush 7, makes contact 5 and hydraulic brake metal parts mutually insulated, and contact 5 is embedded in non-braking surface one side on the brake shoe 4 simultaneously together with insulating bush 7 when making brake shoe 4, insulating bush 7 and contact 5 front end end face, the distance of contact 5 front end end face distance braking surfaces are exactly the limit of wearing and tearing.

Claims

1, a kind of hydraulic brake, the brake shoe (4) that comprises the pump housing (1), piston cavity (2), piston assembly (3) and pair of opposing, brake shoe (4) and piston assembly (3) interlock, it is characterized in that: non-braking surface one side of described brake shoe (4) is embedded with contact (5) and the lead-in wire (6) that slug constitutes, contact (5) and hydraulic brake metal parts mutually insulated.

2, hydraulic brake according to claim 1, it is characterized in that: a slice is fixedly installed on the pump housing (1) in the described a pair of brake shoe (4) that is oppositely arranged, another sheet and piston assembly (3) interlock, described contact (5) are arranged on the brake shoe (4) that fixedly installs.

3, hydraulic brake according to claim 1 and 2 is characterized in that: described contact (5) are column, and front end is provided with flange, and the outside of contact (5) is surrounded by an insulating bush (7), insulating bush (7) and contact (5) front end end face.
