Anti-wear new energy automobile brake mechanism

Abstract

The invention discloses an anti-wear new energy automobile brake mechanism. The anti-wear new energy automobile brake mechanism comprises a brake caliper and a brake disc used in cooperation with the brake caliper, a driving shaft is arranged on the brake caliper, the brake disc is located below the driving shaft, brake lining blocks are arranged at the positions, located on the two sides of the brake disc, of the driving shaft, brake pads are arranged on the brake lining blocks, and guide parts are arranged between the brake lining blocks and the brake caliper. The new energy automobile brake mechanism is different from the prior art, on the basis that single-brake-pad inching brake and double-brake-pad heavy brake can be achieved, the problem that the contact pressure between the two brake pads and the brake disc is different in the heavy brake state can be effectively avoided, especially, high-pressure contact between the brake pads for inching brake and the brake disc can be avoided, and therefore excessive wear of the brake disc for inching brake is effectively avoided in the heavy brake state, the service life of the brake disc is effectively prolonged, and the service cycle of the brake disc is guaranteed, so that automobile owner driving and brake use are convenient.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to an anti-wear brake mechanism for new energy vehicles. Background technique [0002] At present, the existing automobile brake mechanisms mostly use hydraulic pressure to push the brake pads and brake discs to generate pressure to perform the braking work of the car. During the braking process, the surface of the brake pads and the surface of the brake disc will be in frictional contact. When the brake pads are heated, the brake pads will wear out quickly at this time. At the same time, the brake pads will also wear for a long time during the use of the car. The brake pads need to be replaced, otherwise it will cause brake failure, which will give The safety of people in the car poses a threat. At the same time, there will be a large gap between the quality of the brake pads and the price. The price difference between the brake pads with good performance and the brake ...

Problems solved by technology

[0004] Although the above application can take into account the safety of the car while ensuring economy, we have found in the actual use process that when the threaded transmission structure in the above application is in use, because it first drives the first brake pad to contact the brake disc for point braking , but when the second brake pad is subsequently driven to move, it is difficult to cancel the drive of the first brake pad. At this time, the first brake pad will still be squeezed continuously, that is, the pressure between the first brake pad and the brake disc will continue to increase , although it can ensure stable braking, the main thing is that the second brake pad is also in contact with the brake disc at this time, and the friction force provided by the contact pressure between them is sufficient for braking, but the gap between the first brake pad and the brake disc The pressure is much greater than the friction between the second brake pad and the brake disc, but due to its heavy braking state, the first brake pad contacts the brake disc with a pressure much greater than the contact pressure between the second brake pad and the brake disc. In the case of heavy braking, it will further aggravate the wear of the first brake disc and seriously shorten the service life of the first brake pad. Although its price is economical and does not affect braking, compared with the service life of the transmission dual brake pads, In the same cycle, two or even three first brake pads need to be replaced, which not only makes the car owner need to visit the auto repair shop frequently, but even if the price of the first brake pads is economical, but the quantity is large, the cost of two or even three It is completely higher than the cost of traditional double brake pads. Therefore, we propose an anti-wear new energy vehicle brake mechanism
