Automobile resistance reduction and noise prevention eccentric wear free shoe brake and piston

Abstract

The vehicle disappears anti- guards against the sound not to have lopsided wear brake shoe and in the brake can the lasting close union brake shoe and the piston. It with the piston, shoe and the tightening composition, shoe and the piston group synthesizes a lasting close whole with tightening, brake shoe and brake disc throughout maintains parallel and the micro separation by this guarantee. It caused the vehicle shoe and brake disc between has realized the true zero friction in the normal speed, thus effectively has overcome had some vehicles when the normal speed, in the disc brake because the driving shoe pine spacious fills the thing, inclined the bias and the travel which caused with brake disc the unusual friction hinders, psst made noise as well as brake shoe lopsided wear shortcoming, thus has obtained the travel peacefully, the unimpeded energy conservation, applied the brake the part to be durable as well as to apply the brake a safer reliable good effect. It may facilitate reliably applies in each kind of attire with on the disc brake vehicle.

Description

technical field [0001] The invention relates to a brake shoe and a piston which can be permanently and tightly combined in a disc brake of a motor vehicle. Background technique [0002] Disc brakes are widely used in modern motor vehicles because of their better braking effect. The brake is mainly composed of brake disc, shoe and hydraulic wheel cylinder. Among them, the hydraulic sub-cylinder is mainly composed of a brake caliper and a piston embedded in it, and is connected with a sliding rod on the chassis of the motor vehicle. It can slide on the sliding rod along the axial direction of the brake disc in a limited amount; The static plate and the moving plate (relative to the brake caliper)”, the part of the outer circle of the circular brake disc is always between the two shoes, the static plate is connected with the brake caliper, and cannot be moved in any direction ( Compared with the brake caliper), the moving plate is set on the brake caliper and is between the b...

Problems solved by technology

[0005] However, the situation of motor vehicles equipped with disc brakes is often not like this in actual use. They more or less show the following problems: one is that many vehicles transmit "squeak, squeak" from the disc brake position during driving. The noise disturbs the driver; the second is that many vehicles feel slight or serious braking resistance during normal driving, which is manifested by the short sliding distance of the vehicle in neutral and waste oil; the third is that the brake shoes of many vehicles The film, especially the moving film, will be worn out if it is not used for a long time, which will lead to early replacement and unreasonable increase in cost

Therefore, disc brakes are prone to problems such as friction sound, driving resistance and shoe eccentric wear.
