Description
Technical Field
The invention relates to the technical field of new energy automobiles, in particular to an anti-abrasion new energy automobile brake mechanism.
Background
At present, the existing automobile brake mechanism mostly adopts hydraulic pressure to push a brake pad and a brake disc to generate pressure to brake an automobile, the surface of the brake pad is in friction contact with the surface of the brake disc in the braking process, when the brake pad generates heat due to certain braking, the brake pad at the moment can be quickly worn, meanwhile, the brake pad can also be worn for a long time in the using process of the automobile, the brake pad needs to be replaced, otherwise, the brake failure phenomenon can be caused, thereby threatening the safety of personnel in the automobile, meanwhile, the quality and the price of the brake pad can have larger difference, the price difference of the brake pad with good performance and the brake pad with poor performance is larger, in order to consider the price and the performance of the brake pad, users of the automobile can comprehensively select the brake pad, not only the quality is ensured, but also the price factor can be considered, but the performance of the brake pad comprehensively considered is not as good as the brake pad with the best quality when the automobile is braked, it is difficult for the user of the vehicle to decide on safety and price.
According to the patent application No. CN201810264947.1, the automobile brake mechanism based on the screw transmission comprises a fixed arc plate, a brake triggering mechanism, heat dissipation holes, a brake disc, mounting holes and a T-shaped groove, wherein the end face of the brake disc is provided with a plurality of through heat dissipation holes; the end surface of one end of the brake disc is fixedly arranged on the end surface of the driving shaft; a first accommodating cavity is formed in the inner circular surface of the fixed arc plate; the invention utilizes the different brake pads abraded during light braking and strong braking, so that people can realize that the brake pads need to be replaced when the light braking fails, and can continue safe driving by using the strong braking; therefore, the purpose of automobile safety can be achieved while the economy is ensured.
Although the application can ensure the economy and simultaneously give consideration to the safety of the automobile, in the practical use process, the threaded transmission structure in the application is found that when the threaded transmission structure is used, because the threaded transmission structure firstly drives the first brake pad to contact with the brake disc for spot braking, when the threaded transmission structure subsequently drives the second brake pad to move, the driving of the first brake pad is difficult to cancel, the first brake pad is still continuously pressed at the moment, namely the pressure between the first brake pad and the brake disc is still continuously increased, although stable braking can be ensured, the threaded transmission structure mainly needs to be that the second brake pad is also contacted with the brake disc at the moment, the friction force provided by the contact pressure between the second brake pad and the brake disc is enough for braking, but the pressure between the first brake pad and the brake disc is far greater than the friction force between the second brake pad and the brake disc, because the threaded transmission structure is in a heavy braking state, when the first brake pad contacts the brake disc with the contact pressure between the second brake pad and the brake disc, the abrasion of the first brake disc is further aggravated under the condition of heavy braking, the service cycle of the first brake pad is shortened seriously, although the price is economic and the braking is not influenced, but for the service cycle of the transmission double-brake pad, two or even three first brake pads need to be replaced in the same cycle, a car owner needs to frequently visit a car repair shop, and even if the price of the first brake pad is economic, the quantity of the first brake pad is large, the cost of two or even three brake pads is completely higher than that of the traditional double-brake pad, and therefore the abrasion-proof new energy automobile brake mechanism is provided.

when the first ejecting sleeve 43 ejects the deflecting ejecting shaft 44 out of the first through hole 42, the first through hole 42 does not limit the outward expansion and deflection of the deflecting ejecting shaft 44 any more, that is, the deflecting ejecting shaft 44 is ejected out of the first through hole 42, immediately pushed by the first ejecting sleeve 43 to deflect and expand outward, and in the outward expansion and deflection process of the deflecting ejecting shaft 44, the extrusion rubber ring 73 deforms and contracts, and the end of the deflecting ejecting shaft 44 is in contact and abutment with the side edge of the guide frame 41, and when the deflecting ejecting shaft 44 is always positioned on the side edge of the first ejecting sleeve 43, the deflection ejecting shaft cannot contract all the time, and cooperates with the guide frame 41 to limit the transverse position of the deflecting ejecting shaft 44, so that the deflection ejecting shaft is not pressurized and keeps in contact vibration with the brake disc 2, and when the deflecting ejecting shaft 44 is separated from the first through hole 42 and deflects and expands outward, the second ejecting sleeve 51 contacts the side brake pad 12, and drives the second brake pad to contact the brake disc 2 for braking, that is a double brake pad 13 for heavy braking, in the process, the second spring 62 is stressed and contracted, on the basis of the single brake pad 13 inching, when the double brake pads 13 are braked again, the two brake pads 13 are ensured to be in equal pressure contact with the brake disc 2, so that the problem that the inching brake pads 13 are seriously abraded is avoided;
when the brake is cancelled, the motor works reversely to drive the driving shaft 11 to rotate reversely, at the moment, the first ejection sleeve 43 and the second ejection sleeve 51 move reversely and reset, in the process, the first ejection sleeve 43 and the second ejection sleeve 51 cancel ejection of the brake pads 12 successively, the two brake pads 12 can be ejected directly by the second spring 62 to reset, the supplement is needed, in the resetting process of the first ejection sleeve 43, the first ejection sleeve 43 can be separated from the deflection ejector shaft 44 firstly, when the first ejection sleeve is separated, the deflection ejector shaft 44 is ejected by the rubber ring 73 and gathered to the driving shaft 11 for resetting, in addition, in the ejecting process of the second spring 62, the brake pads 12 eject the deflection ejector shaft 44 to enter the first through hole 42, and the double brake discs 13 are reset for continuous spot braking and heavy braking.
