  • Patent number: 10228027
    Abstract: 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.

  • Patent number: 10196062
    Abstract: A method for stopping of a motor vehicle including providing a creep torque via a drive train of the motor vehicle and then increasing, independently of the driver, engine speed of a drive engine of the drive train to increase a drive torque of the drive engine and simultaneously increasing, independently of the driver, a braking torque of a brake system of the motor vehicle to balance the drive torque and the braking torque of the motor wherein the maximum braking torque is as great as the creep torque during a standstill of the motor vehicle. The method then maintains the braking torque and simultaneously reduces the engine speed of the drive engine to point at which the motor vehicle comes to a standstill.
