Abstract

The invention discloses a toe-in angle measuring device of a wheel of a formula racing car, and relates to the field of vehicle detection and positioning. The device comprises a frame, a wheel fixingpedestal, an automatic positioning and clamping device, a horizontal calibrator, a laser emitter and an adjustable calibrated scale with a slide rail; the wheel fixing pedestal with the laser emitteris mounted on the wheel to be measured, and the automatic positioning and clamping device can position the laser emitter in the center of the wheel accurately; and the adjustable calibrated scale withthe slide rail is mounted on a steel pipe in the upper of a car frame, and the calibrated scale on the slide rail is adjusted to measure and position the toe-in angle of the wheels, with different wheelspans, of the formula racing car. The device can carry out measurement without changing a suspension arrangement form, and the wheels, with different wheelspans, of the formula racing car can be measured. Compared with the prior art, the device only measure the wheel of 1 / 4 suspension, a measuring process is simple, accurate and efficient.

Description

technical field [0001] The invention relates to the field of vehicle four-wheel alignment parameters, in particular to a measuring device for the toe angle of a formula racing wheel. Background technique [0002] With the rapid development of China's automobile industry, various racing sports events have been continuously developed and popularized. The Chinese Student Formula Car Competition is a competition for the design and manufacture of formula racing cars that students from colleges and universities form teams to participate in. During the design and manufacture of formula racing cars, the alignment parameters of the wheels play a vital role in the handling stability of the vehicle. Wheel alignment parameters include wheel camber, wheel toe, kingpin caster and kingpin inclination. [0003] In order to ensure the stable straight running of the car, the steering wheel should have an automatic back-to-center function, which is guaranteed by the positioning parameters of...
