FSAE racing car braking safety protection device

Abstract

An FSAE racing car braking safety protection device comprises an existing racing car braking system and an electric control mechanical braking system, wherein the existing racing car braking system ismounted on a half axle for driving wheels to rotate, and the electric control mechanical braking system is connected with the existing racing car braking system in parallel; the existing racing car braking system comprises a brake disc and a brake caliper component; a brake wheel cylinder is connected to the brake caliper component; the brake wheel cylinder communicates with a brake main cylinderthrough a hydraulic pipeline; the brake main cylinder is connected with a brake pedal; an ejecting rod matched with the electric control mechanical braking system is also arranged on the brake wheelcylinder; the electric control mechanical braking system comprises a push rod matched with the ejecting rod, a moment motor, a rotating shaft and a wedge-shaped inclined surface mechanism; a speed sensor is arranged on the internal side of the brake disc; a displacement sensor is arranged under the ejecting rod; a pedal travel displacement sensor is connected to the brake pedal; and the three sensors and the moment motor are all connected with an ECU electric control unit. According to the FSAE racing car braking safety protection device, the active safety performance of a racing car can be improved so that the safety of a racing driver and the safety of the whole racing car can be protected in case of an emergency, the input cost is lower, the structure is simple, the use is convenient, and the practicability is higher.

Description

technical field [0001] The invention relates to the technical field of racing brakes, in particular to an FSAE racing brake safety protection device. Background technique [0002] The FSAE formula racing car is regarded internationally as "the F1 formula racing car in the academic circle". In the multi-station competitions in other places, more and more college students have joined the ranks accordingly. Now the FSAE race is developing rapidly towards faster, lighter and more stable. FSAE formula racing cars are generally running at high speed, and its high braking reliability is the key to ensure its safe and stable operation. The braking performance of FSAE racing cars directly affects the driver's short-term parking safety. With the development of existing science and technology, the electronically controlled mechanical braking system has changed the traditional braking working mode, and has the characteristics of fast braking response, safety and reliability, energy sa...
