Hydraulic disk type brake

Abstract

The invention provides a hydraulic disk type brake which comprises a brake caliper housing (1), brake sheets (2), a brake pump (3), a liquid storage device (4) and an installing rack (5), wherein two parallel guide rods (9) are arranged on the brake caliper housing (1); the brake sheets (2) comprise an outer brake sheet (2.1) which is in sliding connection with the guide rods (9) and an inner brake sheet (2.2) which is in sliding connection with the installing bracket (5); the installing bracket (5) is in sliding connection with the guide rods (9); and the brake caliper housing (1) is integrally shaped with the brake pump (3). Compared with the prior art, the hydraulic disk type brake in the invention has the characteristics of wide application range, higher hydraulic efficiency, higher brake sensitivity, fewer components, low cost and simplicity in assembling.

Description

Technical field: [0001] The invention belongs to the field of brake equipment, in particular to a hydraulic disc brake used for motorcycles and battery cars. Background technique: [0002] At present, the hydraulic disc brakes of the prior art, especially the hydraulic disc brakes of electric vehicles or motorcycles, are divided into four parts: a brake pump assembly, a brake oil pipe assembly, a brake caliper assembly and a brake disc. It is connected to the brake caliper assembly through the brake oil pipe assembly. Although the disc brake with this structure has the characteristics that the brake oil pipe is relatively soft, so that the layout of the hydraulic disc brake is not restricted, the braking torque is more stable than that of the drum brake, and the gap is automatically adjusted after the friction material is worn, but due to the brake pump assembly Installed on the handlebars of motorcycles or electric vehicles, the installation space is limited by the plastic...

Problems solved by technology

Although the disc brake with this structure has the characteristics that the brake oil pipe is relatively soft, so that the layout of the hydraulic disc brake is not restricted, the braking torque is more stable than that of the drum brake, and the gap is automatically adjusted after the friction material is worn, but due to the brake pump assembly Installed on the handlebars of motorcycles or electric vehicles, the installation space is limited by the plastic cover, and the handlebars of motorcycles or electric vehicles that are not special plastic covers cannot be installed with brake pump components, so the application range is small; The dynamic oil pipe is long, especially the brake oil of the rear disc brake, and the return amount of the brake caliper of the motorcycle or electric vehicle is relatively large, so the hydraulic efficiency is reduced and the braking sensitivity is poor; moreover, there are many parts and the production cost is high. And when assembling the disc brake, it is necessary to disassemble the oil pipe through the cover and connect it. Due to the strong technicality, it is difficult for most motorcycle or electric vehicle factories to restore the normal pressure, resulting in poor sensitivity of the disc brake, or even failure.
