Rear suspension four-wheel alignment adjustment device and method when multi-link rear suspension vehicles are assembled

Abstract

The invention discloses a rear suspension four-wheel positioning adjustment device when a multi-link rear suspension vehicle is assembled, which includes a main body frame, a rear suspension clamping unit, a wheel edge movement unit, a wheel edge toe-in camber angle detection unit, an automatic Adjustment unit and controller; the rear suspension clamping unit is fixed on the main frame, which is used to clamp the bracket of the multi-link rear suspension vehicle, simulating the assembly state of the real vehicle and the body; the wheel edge movement unit is installed on the main frame; After the brake disc is clamped, it is used to simulate the wheel jump of a multi-link rear suspension vehicle; and to simulate the wheel center and vehicle body height when the vehicle is off the assembly line; the toe-in camber angle detection unit at the wheel side is installed on the wheel side motion unit; It is used to monitor the toe-in and camber angle of the wheel edge of the multi-link rear suspension vehicle in real time; the automatic adjustment unit is installed to adjust the rear suspension toe-in and camber angle of the multi-link rear suspension vehicle. The invention can solve the problems of difficult and time-consuming adjustment of the toe-in and camber of the rear suspension after the assembly of the whole vehicle is completed.

Description

technical field [0001] The invention belongs to the technical field of automobile assembly, and in particular relates to a rear suspension four-wheel positioning adjustment device and method when a multi-link rear suspension vehicle is assembled. Background technique [0002] At present, after the assembly of the vehicle is completed (after the chassis, body, engine and other parts are assembled), before leaving the factory, the vehicle needs to be adjusted for four-wheel alignment (toe-in, camber adjustment) to ensure that the off-line vehicle The four-wheel alignment meets the design requirements. For the rear multi-link suspension with adjustable toe-in and camber, due to the complex arrangement of various rod systems, after the rear suspension and body are assembled, there is not enough room to adjust the toe-in and camber when the vehicle is off the assembly line. The adjustment personnel do not have enough operating space in the lower part of the vehicle, the adjustme...

Problems solved by technology

[0003] The object of the present invention is to provide a rear suspension four-wheel positioning adjustment device and method when a multi-link rear suspension vehicle is assembled. , when the chassis is sub-assembled (before the chassis and the vehicle are assembled), the rear suspension sub-assembly assembly is detected and automatically adjusted, so that when the vehicle is off the assembly line, only the toe-in adjustment of the front suspension is required, and there is no need to adjust the rear suspension The four-wheel alignment adjustment of the frame shortens the off-line cycle of the whole vehicle, and solves the problem of difficult and time-consuming adjustment of the toe-in and camber of the rear suspension after the assembly of the whole vehicle is completed.
