Abstract
An axle drive for a vehicle includes at least one drivable vehicle axle oriented transversely to a longitudinal direction of the vehicle. A drive shaft extends parallel with the longitudinal direction and receives drive power from an electric motor at an input section and outputs the drive power at an output section. A driven shaft extends parallel with the drive shaft and receives drive power from the output section of the drive shaft at an input section and outputs the drive power to the vehicle axle via a bevel gear arranged at a first end of the driven shaft. A brake, in particular a parking brake, includes a brake disk arranged at a second end of the driven shaft and between the input section of the drive shaft and the input section of the driven shaft with respect to the longitudinal direction.
Claims17
An axle drive for a vehicle comprising at least one drivable vehicle axle oriented transversely to a longitudinal direction of the vehicle, said axle drive comprising
- a drive shaft that extends in parallel with the longitudinal direction of the vehicle and that is configured to receive drive power from an electric motor at an input section and to output said drive power at an output section, wherein the electric motor is connected to the input section of the drive shaft via at least one gear stage;
- a driven shaft that extends offset from the drive shaft at an offset and in parallel with the longitudinal direction of the vehicle between a first end and a second end opposite thereto and that is configured to receive drive power from the output section of the drive shaft at an input section and to output said drive power to the vehicle axle via a bevel gear arranged at the first end;
- and
- a brake having a brake disk that is arranged at the second end of the driven shaft and that is arranged between the input section of the drive shaft and the input section of the driven shaft with respect to the longitudinal direction of the vehicle, wherein a diameter of the brake disc is at least as large as the offset between the drive shaft and the driven shaft.
An axle drive for a vehicle comprising at least one drivable vehicle axle oriented transversely to a longitudinal direction of the vehicle, said axle drive comprising
- a drive shaft that extends in parallel with the longitudinal direction of the vehicle and that is configured to receive drive power from an electric motor at an input section and to output said drive power at an output section;
- a driven shaft that extends offset from the drive shaft and in parallel with the longitudinal direction of the vehicle between a first end and a second end opposite thereto and that is configured to receive drive power from the output section of the drive shaft at an input section and to output said drive power to the vehicle axle via a bevel gear arranged at the first end;
- a brake having a brake disk and at least one brake caliper;
- and
- a housing in which the output section of the drive shaft and the input section of the driven shaft are received;
- wherein the brake disk is arranged at the driven shaft;
- wherein the at least one brake caliper is fastened to an outer side of the housing;
- and
- wherein the at least one brake caliper is arranged diametrically opposite the drive shaft with respect to the driven shaft and wherein a rotational axis of the driven shaft is located between the drive shaft and the least one brake caliper;
- or
- wherein the at least one brake caliper is arranged angularly offset with respect to the arrangement diametrically opposite the drive shaft.
An axle drive for a vehicle comprising at least one drivable vehicle axle oriented transversely to a longitudinal direction of the vehicle, said axle drive comprising
- a drive shaft that extends in parallel with the longitudinal direction of the vehicle and that is configured to receive drive power from an electric motor at an input section and to output said drive power at an output section,
- a driven shaft that extends offset from the drive shaft and in parallel with the longitudinal direction of the vehicle between a first end and a second end opposite thereto and that is configured to receive drive power from the output section of the drive shaft at an input section and to output said drive power to the vehicle axle via a bevel gear arranged at the first end;
- and
- a brake having a brake disk and at least one brake caliper, wherein the at least one brake caliper is arranged beneath the driven shaft when the axle drive is installed in the vehicle so that the at least one brake caliper is accessible from below in an assembled state of the axle drive.
