Multi-axle vehicle double-rear-axle parallelism detection and adjustment method

Abstract

The invention relates to the technical field of vehicle assembly, and discloses a multi-axle vehicle double-rear-axle parallelism detection and adjustment method, which comprises the following steps of S1, calculating a required reference of the double-rear-axle parallelism of a multi-axle vehicle; S2, measuring the parallelism of the middle axle and the parallelism of the rear axle by using a measuring tool, comparing the measured parallelism with a required reference, if the parallelism does not meet the required reference, entering step S3, and otherwise, entering step S4; S3, adding an adjusting gasket on the thrust rod until the measured parallelism of the middle axle and the rear axle meets the required standard after the adjusting gasket is added; and S4, tightening the thrust rod according to requirements, dismounting the measuring tool in the step S2, and completing parallelism detection and adjustment. The measuring tool is used for measuring the parallelism of the middle axle and the rear axle, meanwhile, the adjusting gasket is used for adjusting the length of the single-side thrust rod, too many complex devices do not need to be used for adjustment, the double-rear-axle parallelism detection and assembly processes are reduced, and the vehicle double-rear-axle parallelism assembling and adjusting efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle assembly, in particular to a method for detecting and adjusting the parallelism of double rear axles of a multi-axle vehicle. Background technique [0002] The dual rear axle system of multi-axle vehicles generally includes tires, right rear thrust rod, right front thrust rod, middle axle assembly, left front thrust rod, left rear thrust rod, rear axle assembly, frame assembly, balance suspension support , when assembling the double rear axle system on the production line, the assembler needs to confirm the parallelism of the double rear axle to ensure that the double rear axle system of the vehicle after leaving the factory is in a parallel state and ensure that the wheels can roll in the same direction, which can Keeping the vehicle running straight at high speed can also reduce the problem of abnormal tire wear caused by inconsistent wheel rolling directions. [0003] At present, the field of ...
