Hydrostatic fluid screw brake, to affect the rotary speed of wheels or their axles through a differential, has a low force fluid movement in a circuit, easily interrupted by a pressure control valve to affect wheel/axle speeds

摘要

The hydrostatic fluid screw brake (A) is formed by the screw drive (A.a) and the screw wheel shaft (A.c) with the disks and the connecting rods (C,C.a) and the moving pistons (D1,D2). Through the stroke movements, the fluid is moved into a circuit through the flow valves (G1-G4), and the throttle action of the pressure control valve (F) affects the rotary speed of the wheels.
