The invention relates to the technical field of automobile brakes. The invention discloses a safety mechanism for preventing automobile brake failure. The safety mechanism comprises an engine shaft and an accelerator pedal; a metal block is fixedly installed on the outer side of an extension spring, power lines are fixedly connected to the two sides of the extension spring, a separation mechanismis fixedly installed at the outer ends of the power lines, a separation electromagnet is fixedly installed in a separation chamber, an ejector rod is fixedly installed at the upper end of a buffer spring, and intervention electromagnets are fixedly installed below the accelerator pedal. When the automobile speed exceeds the limit speed value and the centrifugal force generated by a separation discis greater than the tension of the extension spring, a metal block contacts with the power lines to form a closed loop, the separation electromagnet is powered on to generate magnetism to separate the ejector rod from a stabilizing disc, repulsive force generated by power-on between the intervention electromagnets prevents a driver from mistakenly stepping on an accelerator pedal, and the effectof a passive safety mechanism is achieved when braking is overheated and fails.

    本发明涉及汽车刹车技术领域,且公开了一种防止汽车刹车失灵的保险机构,包括发动机轴和油门踏板,所述拉伸弹簧的外侧固定安装金属块,拉伸弹簧的两侧固定连接有电源线,电源线的外端固定安装有分离机构,分离室的内部固定安装有分离电磁铁,缓冲弹簧的上端固定安装有顶杆,油门踏板的下方固定安装有干预电磁铁。该防止汽车刹车失灵的保险机构,通过汽车速度当超出限定速度值时,分离盘产生的离心力大于拉伸弹簧的拉力时,金属块接触从而电源线形成一个闭合回路,分离电磁铁通电产生磁性将顶杆与稳定盘分离,同时干预电磁铁之间通电产生排斥力,防止驾驶员误踩油门踏板,实现了刹车过热失灵时具有被动保险机构的效果。
