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.
