Greek drum brake assemblies for automobiles has a storage

摘要

This invention relates to an assembly of a drum brake for automobiles having a grease storage device, the driver's pedal pressure the master cylinder piston is pushed by the higher oil pressure; Is pressed against the drum in accordance with the movement of the piston that was pressed by the master cylinder brake shoe assembly of the braking action (brake shoe lining and is assembled); Grease groove is formed in the storage device can store the necessary grease for smooth operation of the part for generating the brake shoe assembly and hwakjangryeok; The brake shoe assemblies and hwakjangryeok able to install the generating parts and grease grooves formed backplate attached storage devices; Comprises a brake drum to generate a braking force to the brake shoe assembly and the friction. ; Thus drum brake assembly according to a preferred embodiment of the present invention is grease storage attachment groove is formed on the back plate grease storage sikimeuroseo grease groove is formed in the fixed storage device coupled with the plug type rivets may occur during braking reduction in the brake shoe assembly and the sliding resistance at the time of contact with the drum, the back plate and the rim reduced wear, noise from the rim and reducing slid back plate, grease loss prevention function and the effect of improving the braking force, etc., all of the braking device used in the drum brake apply and can be mounted on.
