Latest Patents
One of his latest patents is a drive arrangement for a four-wheel drive vehicle. This innovative design incorporates a planetary gear set that drives the front wheels, allowing for operation in either direct drive or with a speed increase. The system is intelligently shifted based on the steering angle sensed at the front pair of wheels. To ensure a smooth transition from direct drive to increased speed mode, the planetary gearset is gradually shifted, allowing the planetary gear clutch and/or brake to slip in proportion to the steering angle.
Another significant patent involves a procedure for shifting a transmission composed of several gear units. This procedure is designed to optimize the gear ratio change in the last gear unit, which is crucial for synchronizing the speed of all preceding gear units. By initially releasing all shift linkages and then re-establishing them starting from the last gear unit, unnecessary rotating inertias are decoupled. This innovation allows for a reduction in the size of the shift linkages and synchronizing devices.
