Hydrostatic traction drive

Abstract

A hydrostatic traction drive includes a first hydrostatic motor and at least one drive unit effectively connected with the motor. The motor is connected with a second motor into a modular unit, and the motors are positioned coaxially with respect to each other. At least one of the motors has a variable displacement. Between the motors and/or between at least one motor and the drive unit that is effectively connected with it, there is a clutch that can be disengaged in operation. On the motor-side of the hydrostatic traction drive, it thereby becomes possible to vary the transmission ratio continuously and without interrupting the traction. The clutch connected between the motors makes it possible to disconnect one of the motors and thereby reduce power loss and wear. Output-side clutches make it possible to disengage drive units from the motors.
