An electric drive module comprises a housing, at least one electric motor attached to the housing, a main gear wheel mechanically connected to the electric motor by mechanical gears, a gearbox, where the gearbox input member is driven by the main gear wheel, an axle differential housed in an axle differential housing and driven by an gearbox output, and drive shafts driven by the axle differential, the axis of which is parallel to the axis of the gearbox. At least a portion of the differential housing is rigidly connected to the output member of the gearbox, which allows direct connection of the gearbox and the differential.

A vehicle includes a powertrain and an electric parking brake. A controller activates the electric parking brake in response to the powertrain transitioning to an off state that inhibits production of propulsive torque during an ignition cycle when a vehicle speed is less than a predetermined speed and in a presence of conditions that inhibit the powertrain from transitioning to an on state that permits production of propulsive torque.

A control apparatus of an all-wheel drive vehicle includes a vehicle speed detector, a first clutch, a second clutch, and a clutch controller. The vehicle speed detector detects a speed of the all-wheel drive vehicle. The first clutch is provided between a parking mechanism and a drive force source of the all-wheel drive vehicle, and adjusts first drive force to be transmitted from the drive force source to an output shaft of an automatic transmission of the all-wheel drive vehicle. The second clutch is provided between the parking mechanism and a drive wheel of the all-wheel drive vehicle, and adjusts second drive force to be transmitted from the output shaft to the drive wheel. The clutch controller controls engagement force of the first and second clutches, and disengages the first and second clutches when the speed of the all-wheel drive vehicle is equal to or less than a predetermined speed.

A vehicle parking mechanism according to the disclosure is a mechanism provided in a vehicle power transmission device that transmits power output from an electric motor to left and right axles and through two planetary gear mechanisms and a differential device, wherein, in a carrier of one of the two planetary gear mechanisms and, a piston engaged and disengaged with and from a carrier of the other is slidably provided, wherein the piston is engaged with the carrier of the other planetary gear mechanism when a vehicle is stopped, and wherein the piston is disengaged from the carrier of the other planetary gear mechanism other than when the vehicle is stopped.

A parking lock assembly for a vehicle with an electric drive system, the parking lock assembly comprises a parking gear, an actuator housing containing an actuator and locking lever, and a mounting bracket. The electric drive system has a drive motor, a drive shaft, and a plurality of wheels. The parking gear is fastened between the drive shaft and the drive motor to form a linkage, and the actuator housing is held in a position in close proximity to the parking gear, allowing the locking gear to engage the parking gear to arrest the rotation of the drive shaft and prevent the vehicle from moving. A return spring allows the locking lever to disengage from the parking gear. The mounting bracket allows the actuator housing to be externally mounted to a mounting point located on the vehicle or to a housing surface external to the drive motor.

In a support structure of a power system, the power system includes: an electrical motor; a transmission; and a housing supported by a frame member of the vehicle via a mount arm. The transmission includes a first planetary mechanism having first to third rotating elements, the electrical motor is connected to the first rotating element of the first planetary mechanism, the left and right wheels are connected to the second rotating element of the first planetary mechanism, and the housing is connected to the third rotating element of the first planetary mechanism. A fastening member that fastens the housing and the mount arm is disposed so as to overlap in the axial direction with a connecting portion that connects the third rotating element of the first planetary mechanism and the housing.

An axle of an industrial vehicle, in which a parking brake can be maintained easily. The parking brake is arranged adjacent to a power transmission device outside an axle housing. The parking brake includes a brake housing, a brake shaft supported rotatably around the axis of the brake housing, a brake gear attached to the brake shaft and meshed with a transmission gear, first brake plates attached to the brake shaft, second brake plates attached to the brake housing and alternately arranged with the first brake plates, and a brake piston arranged so as to move toward and away from the plates and in the brake housing for bringing the plates into pressure contact with each other.

An electric drive module comprises a housing, at least one electric motor attached to the housing, a main gear wheel mechanically connected to the electric motor by mechanical gears, a gearbox, where the gearbox input member is driven by the main gear wheel, an axle differential housed in an axle differential housing and driven by an gearbox output, and drive shafts driven by the axle differential, the axis of which is parallel to the axis of the gearbox. At least a portion of the differential housing is rigidly connected to the output member of the gearbox, which allows direct connection of the gearbox and the differential.

A method controls a power train of a vehicle immobilized in a parking position, the vehicle being provided with a parking brake device for immobilizing the vehicle and at least one electric motor. The method includes detecting the slope direction and/or slope data when the parking brake device is in an actuated position, detecting that the parking brake device has switched from the actuated position to a released position, and applying a motor torque setpoint to the electric motor in accordance with the detected slope direction and/or slope data.

A control apparatus of an all-wheel drive vehicle includes a vehicle speed detector, a first clutch, a second clutch, and a clutch controller. The vehicle speed detector detects a speed of the all-wheel drive vehicle. The first clutch is provided between a parking mechanism and a drive force source of the all-wheel drive vehicle, and adjusts first drive force to be transmitted from the drive force source to an output shaft of an automatic transmission of the all-wheel drive vehicle. The second clutch is provided between the parking mechanism and a drive wheel of the all-wheel drive vehicle, and adjusts second drive force to be transmitted from the output shaft to the drive wheel. The clutch controller controls engagement force of the first and second clutches, and disengages the first and second clutches when the speed of the all-wheel drive vehicle is equal to or less than a predetermined speed.
