(3) Rear Suspension Cylinders The suspension cylinder system has three main components:
Front Suspension Cylinders
Rear Suspension Cylinders
Payload Pressure SensorsThe front suspension cylinder is an oil-pneumatic hydraulic cylinder. The front suspension cylinders are the kingpins for the steering linkage. The front suspension cylinders also provide the shock absorber action between the front wheels and the machine frame.The rear suspension cylinder is an oil-pneumatic hydraulic cylinder. The rear suspension cylinders are located in line with the side rails of the frame. A support, which is fastened to the front side of the axle housing, is connected to the frame by a ball joint. The rear suspension cylinders provide the shock absorber action between the rear wheels and the machine frame. The rear suspension cylinders support the rear end of the machine which includes the load.There are four payload pressure sensors on the machine. One pressure sensor is located on each suspension cylinder. The pressure sensors send a signal to the Truck Payload Measurement System. This signal is converted into a payload weight and the data is stored.
