In an electronic parking lock apparatus, a relative rotation angle of an electric motor of an actuator is detected by a relative rotation angle sensor, an absolute rotation angle of the electric motor is calculated according to the relative rotation angle and reference rotation position information obtained by a rotation end limiting portion that limits a rotation end of a rotating component. An absolute rotation angle of the rotating component is detected by using an absolute rotation angle sensor, and the working status of the parking lock is determined according to the absolute rotation angle. The rotation end limiting portion used for obtaining the reference rotation position information of the relative rotation angle sensor and a detected component used for enabling the absolute rotation angle sensor to work to obtain the absolute rotation angle are provided in the same rotating component.

A braking structure for an in-wheel motor drive device includes: an in-wheel motor drive device including a wheel hub bearing unit (11) and a motor unit, the wheel hub bearing unit (11) including an outer ring (12) connected to a road wheel (W) and a brake rotor (BR), inner rings (13) disposed coaxially with the outer ring (12), and a plurality of rolling elements (14) arranged in annular clearance between the outer ring and the inner rings, and the motor unit being configured to drive the outer ring; a carrier member (17) coupled to a vehicle body-side member and attached to and fixed to an inner fixing member (15) for the inner rings (13); and a brake caliper bracket (18) that has its inner end (18b) connected to the carrier member (17) and that supports a brake caliper (19) at its outer end (18a).

An adaptive brake control system for use in Ground Support Equipment (GSE) including a speed control system. The adaptive brake control system includes a distance sensor adapted to measure a distance from an edge of the GSE to an external object and a speed senor adapted to measure a ground speed of the GSE. An actuator, such as a brake actuator, is adapted to cause the speed control system of the GSE to slow or stop the GSE. A controller is functionally associated with the distance sensor, the speed sensor, and the actuator. The controller is adapted to receive inputs from the distance sensor and the speed sensor, and, based on the received inputs, to trigger the actuator to affect slowing or stopping of the GSE.

A radial piston motor comprises cylinder-piston units arranged in a star shape, a housing, an output shaft, an inner axial housing collar, an outer axial shaft collar, an output flange, an output shaft, and a brake positioned at least in certain sections between the inner axial housing collar and the outer axial shaft collar. The output flange is attached to the output shaft. The output flange is attached to the shaft collar radially outside the shaft collar.

A method of increasing engine braking of an engine for a vehicle, the method including: determining the change in kinetic energy of the vehicle over a period; determining the energy output from a drivetrain of the vehicle over the period; comparing the change in kinetic energy to the energy output; and increasing the engine braking of the vehicle when the change in kinetic energy is greater than the energy output over the period.

Provided is an automatic transmission including: an input section to which power generated by a drive source is input; an output section configured to output a drive force; and a gear shifting mechanism configured to change a gear ratio. The power is input to the input section without intervention of a hydraulic power transmission device. The gear shifting mechanism includes a predetermined frictional engagement element for achieving a starting gear ratio of a vehicle. The frictional engagement element includes: a plurality of friction plates arranged with clearances therebetween; a piston movable between a releasing position where the friction plates are brought into a released state, and an engaging position where the friction plates are brought into an engaged state by pressing the friction plates; and an urging mechanism configured to urge the piston so that the piston abuts against the friction plates and the clearances are reduced.

A hydraulic power take-off, PTO, is provided for use with industrial drives. The hydraulic power take-off has a multi-position adapter that allows the PTO to be attached to a prime mover in a multitude of angularly indexed positions while maintaining a gravity-assisted drain and sump for the hydraulic fluid. The multi-position adapter is indexable to selectively block and allow for passage of oil from a tower housing to a clutch housing thus ensuring the hydraulic oil properly drains. As a result, the tower housing is also indexable which allows the PTO unit to be installed in a number of different configurations to meet the demands of the prime mover and the final application of the industrial machine.

An off-road vehicle has four wheels and side-by-side driver and passenger seats. At least two of the wheels are driven by an electric motor powered by batteries disposed in the vehicle.

A power transmission device includes a planetary gear, a reduction gear connected downstream of the planetary gear, a parking lock mechanism including a parking pawl configured to lock one rotation element of the planetary gear, and a barrier wall positioned between the planetary gear and the reduction gear. The parking pawl is rotatably supported on the barrier wall.

An axle drive for a vehicle comprising at least one drivable vehicle axle comprises a drive shaft that extends along a longitudinal direction of the vehicle, starting from a first side of the axle drive, to a second side of the axle drive and that is configured to receive drive power from an electric motor arranged at the first side and to output said drive power at the second side to a driven shaft that extends at the second side of the axle drive offset from the drive shaft and that is configured to output drive power to the vehicle axle via a bevel gear facing towards the first side. The axle drive further comprises a brake, in particular a parking brake, comprising a brake disk that is arranged at the second side of the axle drive, in a manner facing away from the first side, at the drive shaft or at the driven shaft.
