An anti-wear new energy vehicle brake mechanism

Abstract

The invention discloses a brake mechanism for an anti-wear new energy vehicle, which includes a brake caliper and a matching brake disc. A drive shaft is arranged on the brake caliper, the brake disc is located below the drive shaft, and Brake pads are provided on both sides of the brake disc on the drive shaft, brake pads are provided on the brake pads, and there is a gap between the brake pads and the brake caliper. Equipped with guides, this new energy vehicle brake mechanism is different from the existing technology. On the basis of being able to realize single brake pad point braking and double brake pad heavy braking, it can effectively avoid the two brake pads under heavy braking. The problem of the different contact pressure between the brake disc and the brake disc, in particular, can avoid the high-pressure contact between the brake pad for point brake and the brake disc, so that in the heavy braking state, it can effectively avoid excessive wear of the brake disc for point brake, thereby Effectively improve its service life and ensure its service life, so as to facilitate the driving and braking of the car owner.

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
