Description
Technical Field
The utility model relates to a low-speed electric four-wheel vehicle front axle checking fixture.
Background
The low-speed electric motorcycle is developed not from a conventional car but from a golf cart. Since the standards of the vehicle types do not exist in China, domestic manufacturers mostly refer to the standard design of European Union, Japan and other countries, namely, the conditions of small vehicle body size, light vehicle body weight, low highest speed and the like are met simultaneously. In the transverse plane of the automobile, the upper end of the axis of the kingpin slightly inclines inwards, and the phenomenon is called kingpin inclination; in the longitudinal plane of the vehicle, the upper end of the Kingpin axis is slightly inclined backwards, which is known as Kingpin caster; the king pin (Kingpin) is the centre of rotation when the directive wheel turned to on traditional car, and is a thicker round pin axle traditionally. Many independent suspension automobiles do not have the king pin element at present, but the king pin is still used as a substitute term for the steering axis of the steering wheel in the wheel alignment, namely, the steering wheel rotates by taking the king pin as the axis when the steering wheel is steered. The existing detection means and tools can not visually detect the position relation among the backward tilting of the kingpin, the inward tilting of the kingpin, the steering rocker arm and the plate spring seat.
