General InformationThe drum and the axle of the propel system are hydrostatically driven. The drum drive system consists of a piston type pump, a two speed piston type motor, and a planetary gear reducer with an integral brake. This brake is spring applied and hydraulically released. The axle drive system consists of the following components:
A piston type pump
A two-speed piston type motor
An axle with a limited slip differential and a planetary gear reducer for each wheelThe axle can be equipped with an optional brake for each wheel. These brakes are also spring-applied and hydraulically released. The steering pump and fan pump supply charge oil to the propel system.The propel system section of this presentation is divided into segments. The first segments show the location of all electrical and hydraulic components on the machine which are part of the propel system. A brief discussion of each component is provided in these segments. The last two segments explain the operation of the electrical and hydraulic systems. Schematics are used in this segment to trace current through the electrical system and hydraulic oil through the hydraulic system.
