Abstract
A drive axle, in particular an industrial truck drive axle, has an electric motor (2), a differential (4) of a traction drive, which differential is oriented coaxially with the electric motor, and a planetary gear set (3) that is connected between the electric motor (2) and the differential (4). To reduce the effort and expense required to construct the drive axle, the electric motor (2) can be connected in a drive connection by means of a coupling device (5) that is in an operative connection with the planetary gear set (3), with the traction drive, and/or with a work drive. The electric motor (2) can thereby feed a work drive alternatively or in addition to the traction drive.
Claims15
A drive axle, comprising:
- an axle housing;
- an electric motor;
- a differential of a traction drive, which differential is oriented coaxially with respect to said electric motor;
- and
- a planetary gear set connected between the electric motor and the differential,
- wherein the electric motor is connected to the differential of the traction drive and/or with a work drive by a coupling device that is in an operative connection with the planetary gear set,
- wherein the traction drive includes at least one brake, and
- wherein the planetary gear set comprises a ring gear provided with external toothing, which is engaged with a gear wheel of a hydraulic pump.
A drive axle, comprising:
- an axle housing;
- an electric motor;
- a differential of a traction drive, which differential is oriented coaxially with respect to said electric motor;
- and
- a planetary gear set connected between the electric motor and the differential,
- wherein the electric motor is connected to the differential of the traction drive and/or with a work drive by a coupling device that is in an operative connection with the planetary gear sets,
- wherein the planetary gear set has an input-side sun wheel that is connected with a drive shaft of the electric motor, a ring gear and planet wheels located radially between them, mounted on a planet carrier and in engagement with the sun wheel and an internal toothing of the ring gear, wherein the planet carrier is coupled directly or indirectly with the differential, and wherein the ring gear is fastened or released by the coupling device relative to a component which is fixed to the housing and in the released or partly released position is in an operative connection with the work drive, and
- wherein the ring gear is provided with external toothing which is engaged with a gear wheel of a hydraulic pump.
