Suspension four-wheel positioning parameter regulating device and regulating method thereof

Abstract

The invention discloses a suspension four-wheel positioning parameter regulating device and a regulating method thereof. According to the device, only one of the two ends, connected with vehicle frame supporting pieces, of each lower suspension arm is provided with a structure used for driving the end of the lower suspension arm to move in the inside-outside direction of a vehicle, the other end is provided with a structure used for enabling the end of the lower suspension arm to rotate around a shaft extending vertically, and the structure used for driving the corresponding end of each lower suspension arm to move in the inside-outside direction comprises a camshaft. The regulating method of the suspension four-wheel positioning parameter regulating device comprises the step that ball pins of the lower suspension arms can be moved by rotating the front camshafts or rear camshafts. According to the suspension four-wheel positioning parameter regulating device and the regulating method thereof, the double wishbone independent suspension wheel positioning parameter regulating structure is simplified, the camber angle and the kingpin caster angle are regulated only through rear lining bolts and eccentric regulating cams arranged on the rear lining bolts, one regulating cam is omitted, the regulating procedure is simplified, and the regulating efficiency is improved.

Description

technical field [0001] The invention relates to a double-wishbone independent suspension, in particular to a suspension four-wheel alignment parameter adjustment device and an adjustment method thereof. Background technique [0002] figure 1 It is a structural schematic diagram of an existing double wishbone independent suspension. figure 2 yes figure 1 A top view of the lower arm in the double wishbone independent suspension. Such as figure 1 and figure 2 As shown, the double-wishbone independent suspension includes the steering tie rod and the outer ball pin of the steering tie rod, the steering knuckle, the upper swing arm 14 and the upper ball pin 15, the lower swing arm 16 and the lower ball pin 17, the spring 18 and the shock absorber 19 etc., upper swing arm 14 and lower swing arm 16 are installed on the vehicle frame. Through double-wishbone independent suspension structure and kinematics analysis, the toe-in value can be adjusted by adjusting the position of...
