Abstract

The invention discloses a low-drag automobile disc floating brake, which comprises a mounting bracket, a floating caliper body, a piston rod, a guide pin, a first lining, a second lining, a first friction plate and a second friction plate, and the floating The caliper body is installed on the mounting bracket through the guide pin, the guide pin is covered with an elastic piece, the floating caliper body is provided with a piston cylinder, the first oil port and the second oil port, the piston rod is accommodated in the piston cylinder, and the piston rod includes a head The head of the piston rod divides the piston cylinder into a left chamber and a right chamber, one end of the piston rod tail is accommodated in the right chamber, and the other end of the piston rod tail is fixed with the first lining, the second The two linings are fixed on the floating caliper body, and the first lining and the second lining are respectively fixed with a first friction plate and a second friction plate. The low-drag automotive disc-type floating brake proposed by the invention solves the problem of drag caused by the two friction plates still in contact with the brake disc after the release of the traditional floating-caliper brake.

Description

Technical field [0001] The invention relates to the technical field of automobile brakes, in particular to a low-drag automobile disc floating brake and a braking method thereof. Background technique [0002] With economic development, my country's car ownership has gradually increased. In today's shortage of oil resources, energy issues have become the focus of increasing national concern. Energy conservation and environmental protection are particularly important for the design and development of automobiles. [0003] The brake is an important part of the automobile's transmission system. When the automobile brakes, the two friction plates clamp the brake disc to brake the automobile. However, when the brake is released, the friction lining cannot be completely and quickly separated from the brake disc. In the following driving, the friction lining still produces a large drag resistance to the brake disc. This causes useless drag energy loss, reduces the effective use rate of ...
