Rear overhang four-wheel positioning and adjusting device and method for multi-connecting-rod rear overhang vehicle assembling

Abstract

The invention discloses a rear overhang four-wheel positioning and adjusting device for multi-connecting-rod rear overhang vehicle assembling. The device comprises a main body frame, rear overhang clamping and fixing units, a wheel edge moving unit, a wheel edge toe-in camber angle detection unit, an automatic adjusting unit, and a controller. The rear overhang clamping and fixing units are fixedon the main body frame and used for clamping and fixing a bracket of a multi-connecting-rod rear overhang vehicle and simulating the assembly state of a real vehicle and a vehicle body; the wheel edgemoving unit is arranged on the main body frame, and is used for simulating wheel bounce of the multi-connecting-rod rear overhang vehicle after a brake disc is clamped and fixed and simulating a wheel center and the vehicle body height when the vehicle is offline; the wheel edge toe-in camber angle detection unit is arranged on the wheel edge moving unit, and is used for monitoring wheel-side toe-in and camber angles of the multi-connecting-rod rear overhang vehicle in real time; and the automatic adjusting unit is used for adjusting the rear overhang toe-in and camber angles of the multi-connecting-rod rear overhang vehicle. According to the rear overhang four-wheel positioning and adjusting device and a method for multi-connecting-rod rear overhang vehicle assembling, the problems of difficult toe-in and camber adjustment and long consumed time of the rear suspension after the whole vehicle is assembled can be solved.

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.
