Hidden type double-movement disc brake

Abstract

The invention discloses a hidden double-action disc brake, which comprises a left caliper, a left static disk, a left dynamic disk, a traction arm, a right dynamic disk, a right static disk, a right caliper and a brake line. The caliper and the right caliper are connected and fixed by the caliper locking screw, the left static disc and the right static disc are riveted inside the left caliper and the right caliper respectively, and the steel ball raceways of the left static disc and the right static disc are respectively A left steel ball and a right steel ball are provided, and the traction arm is installed on the inner side of the left static disk and the right static disk. In the present invention, the brake pads move in opposite directions during braking, so that the disc is centered and does not deform, prolonging the service life of the disc. When loading and adjusting, just pinch the brake handle to lock the disc brake and it can be adjusted. The adjustment is similar to oil pressure, and the adjustment is simple and easy. ;The trailing arm is hidden in the top cover, so the appearance is simple and beautiful. It is a product that undertakes high-end mechanical disc brakes and low-end hydraulic disc brakes. The market prospect has potential.

Description

technical field [0001] The invention relates to a disc brake, in particular to a hidden double-action disc brake. Background technique [0002] In the current market, disc brakes have become the first choice for bicycle braking systems. At present, single-action mechanical disc brakes, double-action mechanical disc brakes and hydraulic disc brakes are popular in the market. For single-action mechanical disc brakes, due to the unilateral movement of the brake pads, the disc will be pushed to one side and deformed. It is not easy to adjust when loading, and the single-action mechanical disc brakes can see the brake line traction arm, which is not beautiful; similarly, currently Double-acting mechanical disc brakes on the market can see the brake line and trailing arm, which is not beautiful enough; hydraulic disc brakes are prone to oil leakage, thermal expansion, difficult adjustment and troublesome maintenance, and the price is relatively high.
