Hydraulic brake sealing device

Abstract

A hydraulic brake sealing device comprises an oil pressure seat, a brake handle, an oil pressure rod, a connecting rod, a sliding pipe sleeve and an elastic member, wherein the oil pressure seat is provided with an oil pressure chamber and an assembling chamber communicated with the oil pressure chamber; one end of the brake handle is pivoted with the oil pressure seat and is correspondingly assembled at the outside of the assembling chamber; the oil pressure rod is assembled to the oil pressure chamber and the assembling chamber movably; a working head located in the oil pressure chamber, an assembling head located at the outside of the assembling chamber, a first sealing section and a second sealing section both connected to the assembling head and the working head in sequence are arranged at one end of the oil pressure rod; two ends of the connecting rod are assembled to the brake handle and the assembling head of the oil pressure rod respectively; the sliding pipe sleeve is arranged in the assembling chamber in a sliding manner and is fixedly sleeved to the first sealing section; the elastic member comprises an assembling part arranged on the working head, an actuating part and two deformation sections connected between the assembling part and the actuating part. When a driver brakes suddenly, the hydraulic brake sealing device can retard braking force and avoids accidents caused by the sudden brake such as deadlock and slipping of wheels relative to the ground surface.

Description

technical field [0001] The invention provides the technical field of bicycles, in particular to a hydraulic brake sealing device for bicycles. Background technique [0002] In response to the leisure trend and the increase in holiday time, more and more people like to use bicycles as a means of transportation for travel and sports. Riding a bicycle has the characteristics of fitness and environmental protection. In today's emphasis on leisure life, engaging in outdoor leisure activities to experience nature while achieving exercise and health is one of the sports suitable for modern people. [0003] The brake system on a bicycle is the main key to control the speed of the vehicle and maintain safety. The hydraulic disc brake system in the brake system includes a brake handle on the handlebar, a hydraulic caliper on the side of the wheel, connecting the brake handle and The oil pipe of the hydraulic caliper, pressing the brake handle can move the piston group in it to compre...

AI Technical Summary

Problems solved by technology

[0004] However, when the rider encounters an unexpected situation and brakes suddenly, the most common thing is that the rider presses the brake handle hard, causing the front and rear wheels to lock instantly, and the rider will shift the center of gravity due to inertia, causing the vehicle to deviate. The original driving route makes it difficult for the rider to grasp the center of gravity of the bicycle, and cannot effectively control the driving stability of the bicycle, resulting in the bicycle slipping relative to the road surface and prone to rollover or crash accidents
