Abstract: A transfer case, which may be used to distribute the torque selectively between the primary and secondary driving wheels of an automotive vehicle, includes an input element and two output elements located along a common axis. It also includes a magnetic particle clutch and a planetary gear set which are both organized by about the same axis. The clutch and planetary set are connected together such that they provide a direct path through which torque is transferred from the input element to one of the output elements without slippage. The arrangement further provides a slip path through which torque is transferred from the input element to the other output element with slippage, and this path has two segments, one through the planetary set and the other through the clutch and planetary set. The clutch path accommodates slippage and the proportion of torque transferred through the slip path depends solely on the electric current conducted through the clutch.

Abstract: A multi-speed gear hub that includes a hub shaft, a hub sleeve mounted about the hub shaft and at least one planetary gear mechanism for providing a plurality of transmission paths. A bearing is mounted about the hub shaft such that an annular gap is created between the bearing and the hub shaft. A transmission sleeve is disposed in an annular gap for introducing a rotational shift movement into the interior of the gear hub. The configuration of the transmission element does not limit the rotation of the transmission and thus the shifting travel or the shifting angle for each gear ratio is not limited.

Abstract: The present invention is concerned with a continuously variable power split transmission(CVPST) system for use in a hybrid vehicle. The vehicle has a first motor, such as an internal combustion (IC) engine and a second motor, such as an electric motor. The system has a step-up gearbox for providing additional fixed speed ratios to extend overall transmission conversion range (CR) of the system. The system also has a speed variator and a countershaft being operatively connected to the second motor of the vehicle so that any power input applied by the second motor to the countershaft reduces the power flowing through the speed variator. Also, an adjustment of the variator speed ratio iv allows a passage from underdrive iUD to overdrive iOD range of speed ratios in the step-up gearbox to be synchronized.

Abstract: When an input shaft 6 is rotated by an external driving force, the resultant rotational force of the input shaft 6 is transmitted to an offset housing 21 of which rotational force in turn is transmitted to variable rings 39. If, at that time, angular volocities of the variable rings 39 are periodically varied relative to the angular velocity of the offset housing 21, the periodically varying angular velocities of the variable rings 39 are corrected to be substantially constant in a predetermined phase range, allowing only rotational forces having corrected angular velocities to be fetched from the variable rings 39 for transmission to an output shaft 7. Thus, by arbitrarily varying the angular velocities of the variable rings 39 relative to the angular velocity of the offset housing 21, the rotational speed of the output shaft 7 is steplessly varied relative to the rotational speed of the input shaft 7.

Abstract: The handwheel of a vehicle is connected to a handwheel shaft which in turn is connected through a load torque isolating device (overrunning clutch) that acts in either of the two directions of rotation and is connected to a steering shaft that controls a hydraulic arrangement. The hydraulic arrangement controls a steering motor that in turn controls the direction of turning of the vehicle.

The overrunning clutch includes a hub connected to the steering shaft and is movable by the handwheel shaft, the hub being wedgable against the clutch housing for being driven by the second motor by two jamming rollers that each acts in one direction of rotation and can be released by rotating the handwheel shaft.

The clutch assembly is controlled by an electronic control unit which responds to a variety of system parameters such as the front and rear rack positions, forward/reverse indication and the speed of the vehicle.

Abstract: An oscillating rachet style continuously or infinitely variable transmission is disclosed herein, that is, one which, in its operation, relies on a plurality of different successive intermediate rotations that vary in speed and direction in accordance with their own respective oscillatory waveform, each waveform being out of phase with one another in a predetermined way. These intermediate rotations are used to convert the rotational input to a plurality of uni-direction output rotations, without the aid of any over-running clutches. These later outputs vary in speed in accordance with their own respective waveforms and are used to produce a modified rotational output.
