Problems solved by technology

[0004] However, when driving a bicycle on intense or off-road roads, there will often be continuous intermittent braking, that is, when the piston group moves and pushes the oil to the oil pipe, the oil seal is excessively worn by the back and forth friction in the piston group oil chamber, and the oil seal is due to temperature fluctuations. It is easy to accelerate aging and cause oil leakage, resulting in poor braking effect, which seriously affects the safety of driving

Abstract

The invention discloses a hydraulic brake sealing device, which comprises an oil cavity seat, a brake handle, a piston group and an elastic member, wherein the oil cavity seat is provided with an oil cavity and an interface is arranged at the bottom end of the oil cavity for an oil supply pipe to assemble; one end of the brake handle is pivoted to the oil cavity seat; the piston group comprises a driving rod and an actuating rod; one end of the driving rod is assembled to the brake handle; one end of the actuating rod is assembled to the other end of the driving rod; the other end of the actuating rod is a work head and is positioned in the oil cavity; a convex ring is annually arranged at the circumferential side of the work head; at least one oil seal is sleeved on the actuating rod; the actuating rod is contacted to the surface of the oil cavity; the elastic member is sleeved on the work head and is provided with a lateral surface attached to and supported against the surface of the oil cavity; a convex part is arranged at one end of the elastic member and is provided with a penetrating hole in which the work head is sleeved; and the convex part is integrally formed and connected with the lateral surface by a U-shaped part. The hydraulic brake sealing device disclosed by the invention can be used for preventing oil from leaking and pushing and supporting the oil to an oil pipe more really so as to obtain stable and real brake effect.

Description

technical field [0001] The invention relates to a sealing device, in particular to a hydraulic brake sealing device. Background technique [0002] The brake system on the bicycle is the key to control the speed of the vehicle and maintain safety. In the brake system, such as the hydraulic disc brake system, it is mainly equipped with an oil chamber seat with built-in oil on the handlebar. One end is provided with a brake handle that can be used for pulling, and the other end of the oil chamber seat is provided with an oil pipe connected to the brake caliper, so that when the user presses the brake handle, the oil in the oil chamber seat can be squeezed into the oil pipe , and then push the pad in the brake caliper to clamp the disc on the wheel to achieve the purpose of braking. The hydraulic brake system can greatly improve its anti-wear ability through the characteristics of high oil viscosity without arbitrary pressure reduction, and it is easy to maintain balance to imp...
