The invention relates to an auxiliary device suitable for preventing overheating of brake pads during frequent braking, and belongs to the technical field of automobile braking. The auxiliary device comprises a first brake pad, a second brake pad, a first brake caliper, a second brake caliper, a hydraulic master pump, an electric three-way valve, a first liquid distribution pipe and a second liquid distribution pipe; the first brake pad is arranged in the first brake caliper, the second brake pad is arranged in the second brake caliper, the first brake caliper and the second brake caliper are each provided with a liquid passing cavity, the liquid passing cavities are connected with first pistons and second pistons in a sliding mode, the number of the first pistons in each liquid passing cavity is two, and the two first pistons are fixedly connected with brake friction plates. According to the automobile brake disc, the composite brake disc formed by combining the two brake discs is arranged, the two brake discs can be alternately used, and therefore the situation that overheating is caused by frequent braking of a single brake pad can be effectively avoided, the automobile brake disc is suitable for the driving environment needing frequent braking, and the safety of the automobile brake function is effectively improved.

    本发明涉及一种适用于频繁制动防刹车片过热的辅助装置,属于汽车制动技术领域,包括一号刹车片、二号刹车片、一号制动钳、二号制动钳、液压总泵、电动三通阀、一号分液管和二号分液管,一号刹车片与二号刹车片固定连接,一号刹车片置于一号制动钳内,二号刹车片置于二号制动钳内,一号制动钳和二号制动钳均设置有通液腔,通液腔滑动连接有一号活塞和二号活塞,每个通液腔内的一号活塞均设置有两个,两个一号活塞均固定连接有制动摩擦片。本发明中,设置有通过两个刹车盘组合而成的复合式制动盘,两个刹车盘可交替使用,从而可有效避免单一刹车片频繁制动造成过热的情况,适用于需要频繁制动的驾驶环境,有效提高了汽车制动功能的安全性。
