Problems solved by technology

However, due to the inertia of the running wheel, after the wheel is locked, the wheel will still slide for a certain distance, and the wheel parts are easy to wear
In addition, in rainy and snowy weather, due to the slippery road surface, brake lock-up will cause certain dangers.

Embodiment 1

[0025] Figure 1-2 Shown is a kind of bicycle braking device, and this braking device can not only be used for bicycles, but also can be used on the equipment that needs to brake such as motorcycle or automobile. combine Figure 1-2 As shown, the brake device includes a hub assembly 1 and a brake disc 3, the hub assembly 1 is rotatably connected to the brake disc 3 around its axis, and a plurality of brake discs 3 and the hub assembly 1 are arranged between A spring 2 that deforms to gradually reduce the rotational speed of the hub assembly 1. Springs are used in this embodiment, and other buffer devices such as air bags or hydraulic devices can also be selected. When the bicycle is running normally, the brake disc 3 rotates with the hub assembly 1. When braking, as the braking force acts on the brake disc 3, the brake disc 3 remains stationary, and the spring 2 between the brake disc 3 and the hub assembly 1 gradually deforms into a hub Assembly 1 provides cushioning to gr...

Embodiment 2

[0029] image 3 , 4 Shown is another kind of braking device, this embodiment is basically the same as Embodiment 1, the only difference is that: in Embodiment 1, the brake disc 3 only includes a large disc on the outer edge, and the large disc is directly connected to the connection disc 12, and no small disc is arranged in the middle. The disc is used as an adapter disc; in this embodiment, the brake disc 3 is connected to a smaller adapter disc through screws, and then connected to the hub assembly 1 through the adapter disc.

Embodiment 3

[0031] Figure 4 Shown is yet another braking device, this embodiment is basically the same as Embodiment 1, the difference is that: the hub assembly 1 only includes the hub 11, and one end of the hub 11 is integrally formed with a ring of flanges 111 . The flange 111 extends away from the hub 11 from the surface of the hub 11 (the peripheral surface of the above-mentioned end), that is, extends outward along the radial direction of the hub 11 . The installation slot 121 is defined on the flange 111 , and the connecting shaft 31 is disposed on the brake disc 3 .

Abstract

The invention provides a brake device which comprises a hub assembly (1) and a brake disc (3), wherein the hub assembly (1) is rotatably connected to the brake disc (3); at least a spring (2) capable of generating deformation during braking to gradually decrease the rotation speed of the hub assembly (1) is arranged between the hub assembly (1) and the brake disc (3); one of the hub assembly (1) and the brake disc (3) is provided with at least a mounting groove (121), and the other one is provided with a connecting pin (31) corresponding to the mounting groove (121); the connecting pin (31) is inserted in the mounting groove (121) in a sliding mode; the spring (2) is arranged in the mounting groove (121); and one end of the spring (2) is connected with the connecting pin (31). The brake device is used for providing buffer for braking so as to prevent the brake from being locked during braking.

Description

technical field [0001] The invention relates to a braking device. Background technique [0002] In the prior art, disc brakes for bicycles and the like include a hub and a brake disc, and the hub and the brake disc are usually rigidly connected, such as fixedly connected by screws or the like. When the braking force acts on the brake disc, since there is no buffer between the two, the hub speed (wheel speed) will drop rapidly. When the braking force exceeds the friction force between the wheel and the ground, the wheel will be locked and completely locked. The wheels will reduce the friction between the tires and the ground, that is, the brakes are locked. However, due to the inertia of the running wheel, after the wheel is locked, the wheel will still slide for a certain distance, and the wheel parts are easy to wear. In addition, in rainy and snowy weather, due to the slippery road surface, brake lock-up will cause certain dangers. Contents of the invention [0003] I...
