Hydraulic transmission for front loader - has double pumps with added output for full torque to drive each side of vehicle

摘要

The front loader is driven by a hydrostatic transmission with a double pump (a, b) whoe outputs are added for full torque, and with only one pump operating for partial torque. Each pump drives the wheels on one side of the vehicle. The flow distribution from each pump is passed through a distribution valve before being applied to the wheels. The system operates purely hydraulically to cover a wide range of torques, with no separate mechanical components required.
