Mechanical disc brake with brake pads in two-way adjustment and compensation

Abstract

The invention discloses a mechanical disc brake with brake pads in two-way adjustment and compensation. The mechanical disc brake comprises a disc brake main body and a connecting bracket, wherein the disc brake main body comprises a casing, an adjusting device, brake pads and a rotating arm; the casing comprises a left casing and a right casing, which are fixedly connected into an integral structure; the brake pads are respectively mounted on the left casing and the right casing; a hollow structure is formed in the inner part of the right casing; the adjusting device is mounted in the hollow structure of the right casing; one end of the adjusting device protrudes out of the right casing and is connected with the rotating arm; two mounting sleeves are arranged on the outer surface of the right casing; the connecting bracket is connected with the mounting sleeves through guide columns. According to the mechanical disc brake disclosed by the invention, through the mutual cooperation of the disc brake main body, the connecting bracket and a disc brake plate, the two-way adjustment of the brake pads is realized, and the central positions of the left brake pad and the right brake pad can be adjusted; the brake pads are balanced in applied force and bear little load, and the abrasion is reduced; besides, the mechanical disc brake disclosed by the invention has the advantages of being free of oil, convenient to use and low in manufacturing cost.

[0002] At present, the brake devices commonly used for bicycles, electric vehicles and motorcycles on the market include mechanical disc brakes and oil brakes. Among them, oil brakes are mainly used for electric vehicles and motorcycles. The high price of oil brakes is not conducive to popularization and application. Oil brakes are prone to oil leakage during use, resulting in unsatisfactory braking effects. Mechanical disc brakes are often used on bicycles, but are rarely used on electric vehicles and motorcycles. At present, the mechanical disc brakes used on bicycles are basically unilaterally driven. Mechanical disc brake, that is, press the disc brake disc through the brake pad on one side, so as to drive the disc brake disc to press the brake pad on the other side together to achieve the purpose of braking. The mechanical disc brake is fixed on the fixed frame and passed through the fixed frame. Fixed on the frame, due to the unilateral drive and the fixed position of the mechanical disc brake, it is easy to cause excessive force on the brake pads pressed against the disc brake disc during braking, causing serious wear and tear, and the distance between the brake pads and the disc brake disc becomes larger after wear. The force of the brake pads on the disc brake disc becomes smaller. At this time, the force can be increased by replacing the brake pads, or the method of compensating and adjusting the brake pads can be used to make the installation position of the worn brake pads close to the disc brake disc, so as to This increases the force of the brake pads on the disc brake disc

When replacing the brake pads, it can be ensured that the disc brake disc is basically located at the center of the brake pads. However, this method requires the use of tools to disassemble the entire mechanical disc brake device and then replace the brake pads. It cannot be adjusted anytime and anywhere. It will also cause the problem that the replaced brake pads are incompletely used and wasteful. However, the method of compensating and adjusting the brake pads currently mainly includes two ways of one-way adjustment and two-way adjustment. The one-way adjustment is mainly through the adjustment device. One of the brake pads is compensated and adjusted so that the brake pad with greater force is close to the disc brake disc, so that the brake pad can generate sufficient force on the disc brake when braking. This adjustment method is simple in structure, but through one-way adjustment The method can only adjust the brake pad on one side, and the other brake pad cannot be adjusted, so it is easy to cause the disc brake disc to deviate from the center position of the two brake pads, and the brake pad that is biased to one side of the disc brake disc may easily lead to unsatisfactory braking effect; In the way of two-way adjustment, in addition to setting the adjustment device at the end of the brake pad with a larger force, an adjustment device is installed on the outside of the other brake pad to form a two-way adjustment. This adjustment method can compensate and adjust the two brake pads separately. , and through manual adjustment, it can be basically ensured that the disc is located at the center of the two brake pads, but the mechanical disc brake with the adjustment device cannot be applied to electric vehicles or motorcycles, because the braking position of electric vehicles or motorcycles is relatively closed, plus The installed adjustment device is located on the inside, and the owner cannot compensate and adjust the brake pads anytime and anywhere. At the same time, the installation of the adjustment device increases the cost, and the volume and thickness of one end of the brake pad become larger, resulting in the need to make adjustments during installation, which is inconvenient to install.
