Problems solved by technology

Its shortcomings are: the disc is easy to deform, and the brake pads are easy to wear
Its disadvantage is: easy to leak oil, the brake oil should be replaced regularly
If the oil is heated, especially when braking continuously in hot weather, it will expand a lot and just push the brake pads outward, which may wear, drag, or even kill the disc

Embodiment Construction

[0026] The present invention will be further described below in combination with specific embodiments and accompanying drawings.

[0027] like Figure 1-8 As shown, a bicycle dual-brake mechanical disc brake device includes an upper cover 2 and a lower cover 15, and a power biaxial rotor group 3 is placed in an inner cavity 37 between the upper cover 2 and the lower cover 15. The power The biaxial rotor group 3 includes a biaxial connecting rod 21, a first stator 18, a first rotor 20, a second stator 22, a second rotor 23, and a ball 19. The biaxial connecting rod 21 has a first shaft arm 24 and a The second shaft arm 25 .

[0028] figure 1 , 2 , 3, 4, 5, for the convenience of explanation, Figure 5 2 parts of the middle and upper cover are cut off. The first rotor 20 is installed in the first shaft arm hole 26, the shaft hole 38 of the first stator 18 is penetrated in the rotating shaft 29 of the first rotor 20, the bead groove of the first stator 18 and the first rotor...

Abstract

The invention discloses a bicycle double-brake mechanical disc-braking device which comprises an upper cover and a lower cover. A power double-axis rotor set is arranged in an inner cavity between the upper cover and the lower cover, and comprises a double-axis connection rod, a first stator, a first rotor, a second stator, a second rotor and roll balls. Brake pads are fixed on the inner surface of the first rotor and the inner surface of the second rotor respectively. By means of the bicycle double-brake mechanical disc-braking device, a disc can not easily deform, the brake pads can not be easily abraded, the braking effect is good, the bilateral braking effect of oil pressure is achieved, and the phenomenon of oil leakage can not occur. The bicycle double-brake mechanical disc-braking device is low in cost, simple in structure, and practical.

Description

technical field [0001] The invention belongs to the field of bicycle disc brakes, in particular to a bicycle double-brake mechanical disc brake device. Background technique [0002] The bicycle disc brake is composed of a brake disc connected to the wheel and a brake device on the edge of the disc. When braking, the brake pads are pushed to clamp the brake disc to produce a braking effect. At present, it is distinguished according to the way the brake is actuated, or the medium that the actuating brake pad holds the disc, one is the brake line, and the other is oil. Mechanical disc brakes rely on the tension of the brake line to make the brake pads in the caliper rub and clamp the disc to produce a braking effect. Hydraulic disc brakes use oil as the medium, pull the brake handle to make the piston compress the oil, and the pressure goes straight from the oil pipe to the caliper, thereby pushing the piston in the caliper to drive the brake pads to clamp the disc. [0003]...
