The invention discloses an electric auxiliary braking system of a forklift, which comprises a brake pedal assembly, a brake master cylinder, an electric push rod, a pedal travel sensor, a push rod travel sensor, a whole vehicle control unit ECU (electronic control unit), a brake oil can, a whole vehicle display, a wheel side brake cylinder, a pressure sensor and the like. And meanwhile, an ejector rod in the brake master cylinder is pushed to move downwards, a piston in the brake master cylinder moves downwards and drives brake oil in a brake oil pot to enter left and right wheel side brake cylinders, and finally the brake cylinders press friction plates to brake wheels. A pedal travel sensor installed on a pedal assembly can record the pedal travel, pressure sensors installed on left and right wheel side brake cylinders can record the brake oil pressure of the left and right cylinders, the brake oil pressure and the brake oil pressure are fed back to an ECU together, and the ECU can synchronously integrate and store pedal travel information and brake oil pressure information into a built-in RAM. Meanwhile, the information is displayed on a whole vehicle display for an operator to refer.

    本发明公开了一种叉车的电辅助制动系统,包括制动踏板总成、制动总泵、电动推杆、踏板行程传感器、推杆行程传感器、整车控制单元ECU、制动油壶、整车显示器、轮边制动分泵、压力传感器等,通过纯人力液压制动时,踩下制动踏板,带动转轴摇臂顺时针旋转,同时推动制动总泵中顶杆向下移动,制动总泵中活塞下移并驱动制动油壶里制动油进入左右轮边制动分泵,最终制动分泵通过顶压摩擦片使车轮制动。安装在踏板总成上的踏板行程传感器会记录踏板行程、安装在左右轮边制动分泵上压力传感器会记录左右分泵制动油压力,一同反馈至ECU,ECU会同步将踏板行程信息和制动油压力信息整合存储至其内置的RAM中,同时显示在整车显示器供操作员参考。
