Problems solved by technology

However, the creators found that in the aforementioned patents, no matter whether it is a convex post and a spiral groove or a cam post and a ball rail, when foreign objects, such as dust, sand or iron filings, etc., run into the cam mechanism, it will easily cause the cam The mechanism is stuck, so that the brake device is useless
In addition, the cam mechanism will also produce corrosion, which will also cause the brake device to fail to function normally.

Embodiment Construction

[0031] Please refer to Figure 1 to image 3 As shown, the disc brake device 1 provided by the first preferred embodiment of the present invention mainly includes a base 10, a brake disc 20, two brake arms 30a, 30b, two brake pads 35, and a tension controller 40 , a positioning device 50 and a brake cable 60, wherein:

[0032] The base 10 has a shaft hole 11 , a boss 12 located above the shaft hole 11 , a through hole 13 , a screw hole 14 , and two fixing holes 15 . The base 10 passes through two lugs 92 on the front fork or rear fork 91 of a bicycle or motorcycle (not shown) frame by means of two screws 16, and then locks in the two fixing holes 15 respectively, so that the base 10 fixed.

[0033] The brake disc 20 is fixed on a hub (which can be a front hub or a rear hub) 93 and can rotate together with the front (rear) wheel (not shown). The method of fixing the brake disc 20 on the wheel hub 93 is a well-known technique, and will not be repeated here.

[0034] Each brak...

Abstract

The disc brake device of the present invention comprises: a base, fixed on a predetermined position of a vehicle frame; a brake disc, fixed on a wheel hub and can rotate together with the wheel hub; two brake arms, pivotally arranged on the base, They are respectively located on the two sides of the brake disc, and can swing toward or away from the brake disc; the two brake pads are respectively arranged at predetermined positions inside the brake arm so that they respectively correspond to the two sides of the brake disc and are located away from the center of the brake disc. A predetermined position at a certain distance, and in the initial state, there is an appropriate distance between the two brake pads and the brake disc, and a brake cable is connected to the brake arm to drive the two brake arms to swing, so that the brake pads are pressed against Brake disc to produce the effect of braking.

Description

technical field [0001] The invention relates to a brake device, in particular to a disc brake device. Background technique [0002] Ordinary disc brakes are mostly used in automobiles or motorcycles, and the driving method is mostly to use hydraulic pressure to drive the brake pads to press against the brake discs to produce a braking effect. In general, a disc brake device driven by hydraulic pressure has a problem of high cost. Therefore, we rarely see disc brakes [0003] Applied to bicycles. [0004] In the prior art, there is a device that drives the brake pads to press against the brake disc in the form of a cable. Taiwan New Patent Publication No. 478482 discloses a disc brake device, which utilizes the cooperation between the boss and the spiral groove, so that when the boss moves in the groove, the brake pad can be driven to press against the brake disc. In addition, Taiwan New Patent Publication No. 410788 discloses another disc brake device, which is provided ...
