Electronically controlled dampener for hydrostatic transmission |
摘要 |
A hydrostatic transmission including a fluid motor and a variable displacement fluid pump in fluid communication with the motor and having a first and a second, greater, fluid displacement rate. The pump is mounted on a block having an outer surface, a passage through which fluid flows from the pump to the motor, and a first and a second fluid bleed hole extending from the passage to the outer surface. The passage and a sump external to the pump are in fluid communication through the bleed holes and the void of a sliding element disposed within a bore in the block when the pump is operating at its first rate and the sliding element is in a first position. The first bleed hole and the sump are substantially out of fluid communication when the pump is operating at its second rate and the sliding element is in a second position.
