The invention discloses an automobile brake auxiliary device, and belongs to the technical field of automobiles. The device aims to solve the problem that when an existing automobile is braked emergently during high-speed running, the braking distance is too long and unsafe . The device is arranged on a bottom plate connected with a front axle and a rear axle. A ratchet supporting leg is sleeved on the rear axle. When the automobile runs at a high speed, a speed sensor outputs a signal, an electronic controller acquires the signal and sends an instruction to an electromagnetic switch, and theelectromagnetic switch is closed. During emergency braking, a brake pedal is stepped to the bottom, current reaches a motor of an electric lock from the electromagnetic switch, and the motor rotates to unlock the electric lock. When a friction plate falls down and touches the ground, a stop valve of a jack is opened. A kinetic energy spring pushes a pressing rod and a frame push rod to move, and the frame push rod pushes a push rod to rotate. The push rod drives a ratchet wheel hollow shaft to rotate, ratchet wheel supporting legs are promoted to press the friction plate to the road surface and jack up the roof, and wheels do not leave the road surface. Friction between the friction plate and the road surface reduces automobile speed and shortens braking distance. The device is mainly usedfor emergency braking of automobiles in high-speed driving.
汽车刹车辅助装置属于汽车技术领域。现有汽车在高速行驶中紧急制动时,制动距离过长不安全。本装置要解决上述问题。本装置安置在与前后桥连接的底板上。棘轮撑腿套在后桥上。汽车进入高速行驶,速度传感器输出信号,电子控制器获取信号,向电磁开关发出指令,电磁开关闭合。紧急制动时,制动踏板踩到底,电流从电磁开关到达电动锁的电机,电机转动打开电动锁。摩擦板落下触地,千斤顶的截止阀打开。动能弹簧推动压杆、框架推杆移动,框架推杆推动推杆转动。推杆带动棘轮空心轴转动,促使棘轮撑腿把摩擦板压向路面且把车顶起,车轮不离开路面。摩擦板与路面摩擦降低汽车速度,缩短制动距离。本装置主要用于高速行驶中汽车紧急制动。
