Abstract
The invention relates to a hydrostatic drive, preferably for an earth-moving vehicle, such as a wheel loader, comprising two reciprocating-piston rotary motors of the inclined-axis or inclined-disk type. The reciprocating-piston rotary motors have an angle of inclination which are adapted to be controlled to decrease toward zero as the torque decreases and the velocity increases, and which each is coupled to an input shaft of a shiftable transmission. The shiftable transmission comprises two input shafts, which are coupled to two reciprocating-piston rotary motors, and each input shaft is adapted to be coupled to a common output shaft by means of one of at least two shiftable gear stages.

A hydrostatic drive comprising two reciprocating-piston rotary motors, said motors having an angle of inclination adapted to be controlled to decrease toward zero as the torque decreases and velocity increases, and each motor being separately coupled to an input shaft of a shiftable transmission, each input shaft being adapted to be coupled to a common output shaft by means of one of at least two shiftable gear stages.
