Rear Axle Assemblies

rear axle assemblies Operators responsible for locating and setting rear axles to the proper curb height now get a welcome lift from four counterbalanced handling systems that produce zero gravity for unusually easy operation. The air-operated Ergo-Arms provide an ergonomic edge for four workers at two stations on the assembly line.

Vehicles arrive at the first station with the rear axle and leaf springs in place and the shock absorbers hanging loose, ready for their nuts to be tightened. An Ergo-Arm on each side of the line is used to compress and set the axle to curb height in relation to the vehicle frame rail. Then, the axle moves onto a self-locating nest that sets the shocks in position. Using a combination of pneumatic and electric nut runners, the two operators tighten 6 to 8 nuts on the shocks and leaf spring hangers. All of this is done as the vehicle moves at line speed through the station and on to the second station where two more operators use Ergo arms to perform additional tightening tasks.

Three different types of springs and three different shocks are run in production. Three different nests are used to accommodate this mix. Also, each nest has two different sets of nests to handle axles for either two-wheel or four-wheel drive vehicles. Each nest, which serves as end-of-arm tooling, is bolted to a plate on the end of its respective arm. The Ergo arms are mounted from overhead rails in a bridge system parallel to the assembly line.

Two actuating cylinders on each arm provide strength and safety. An integral handle with control buttons is included. Each arm features a balance system designed to produce zero gravity for unusually easy operation. The operator can raise and lower the arm and its load with finger-tip control. A high balance button puts the arm in a transport mode. The balance fixture button produces a zero gravity condition as the arm compresses the axle to curb height. The operator then hits a low balance button to lock the arm with the axle in position ready for the nuts to be tightened.

Examples of other precision equipment delivered by the company include transfer systems, assembly systems, blank destackers and loaders, and high-pressure wash and deburr systems.
