Abstract

The invention discloses a brake drum device for an automobile. The device comprises a brake drum body, and is characterized in that the inner side of the brake drum is provided with an drum inner bottom plate, the bottom surface of the drum inner bottom plate is provided with a chilled water pipeline, one side of the chilled water pipeline is provided with a front brake shoe sheet, and the other side of the chilled water pipeline is provided with a rear brake shoe sheet; a main limiting board is installed on one side of the top end of the front brake shoe sheet, a brake branch pump is installed below the main limiting board, return spring bolts are installed at the top end of the main limiting board, and return spring limiting holes are both formed in the front end face of the front brakeshoe sheet and the front end face of the rear brake shoe sheet; and the return spring limiting holes are connected with the return spring bolts through return springs, and ceramic fiber brake pieces are both installed on the outer side of the front brake shoe sheet and the outer side of the rear brake shoe sheet. According to the device, due to the fact that the chilled water pipe is installed inthe drum inner bottom plate, a harmful effect of overheating expansion of the whole device is avoided.

Description

Technical field [0001] The invention relates to the technical field of drum brakes, in particular to a brake drum device for automobiles. Background technique [0002] Drum brakes have been used in automobiles for nearly a century, but due to its reliability and powerful braking force, drum brakes are still installed on many models (mostly used on the rear wheels). It is fixed to the tire and rotates at the same speed. When braking, hydraulic pressure is used to push the brake shoe into contact with the inner edge of the brake drum, and the friction generated by the contact can restrain the rotation of the tire to achieve the purpose of braking. The drum brake is composed of the brake bottom plate, brake cylinder, brake shoe and other related connecting rods, springs, pin nails, and brake drum. Currently, it is generally installed on the rear wheel. Drum brakes have lower cost and higher absolute braking power. The inner surface of the brake drum of drum brakes is where the br...
