Hydrostatic vehicle propulsion system, has traction control valve system with two one-way relief valve lines connected to hydrostatic circuit, where valve system applies similar inlet pressure to two rear wheel motors

摘要

The system has a fluid displacement pump (14), and a hydrostatic circuit (18) fluidly connected to the pump and fluid displacement motors in a closed loop. A traction control valve system (12) comprises two one-way relief valve lines (24, 30) connected to the hydrostatic circuit. The lines flow in two directions, respectively, and the valve system applies similar inlet pressure to two rear wheel motors (16LR, 16RR).
