  • Patent number: 11131375
    Abstract: A disconnect including: an input hub; an output race including a radially inner surface with ramps; wedge plate segments radially disposed between the input hub and the output race, each segment including a ramp in contact with an outer race ramp; an actuator cage; and an actuator plate. For a connect mode, the input hub, the wedge segments, and the output race transmit torque from an electric motor of an electrically-powered vehicle to a wheel of the vehicle. In a disconnect mode, relative rotation between the input hub and the output race is enabled. To transition from the connect mode to the disconnect mode: the actuator plate is displaced by an actuator; the actuator plate axially displaces the actuator cage; and the actuator cage circumferentially displaces the wedge plate segments to decrease or break frictional contact between the wedge plate segments and the input hub.

  • Patent number: 6247197
    Abstract: A brush assembly includes a distributor having a slot matrix formed in an outer surface of the distributor, the slot matrix including a plurality of longitudinal slots intersecting a plurality of annular slots. The brush assembly further includes a housing having an inner surface abutting the outer surface of the distributor, a brush mounted on the housing and a shaft. During use, the flow of liquid from the shaft to the housing flows through the longitudinal slots and annular slots of the distributor. By appropriately selecting the dimensions and numbers of these slots, the flow of liquid from the shaft to the housing is readily redistributed. For example, the flow of liquid is redistributed to provide a greater amount of liquid to the ends of the brush than to the center of the brush.

  • Patent number: 6189668
    Abstract: A gear pump mechanism shown in a variety of applications to control rotational output. Control of the output from the gear pump and feed to the gear pump of hydraulic fluid or oil can be controlled to establish conditions from free wheeling to fully locked. The gear pump includes a sun gear and planetary gears. The sun gear is attached to an output shaft while the planetary gears are rotatably mounted to the pump housing. Through rotation of the housing and control of the flow through the gear pump, relative rotation of the output shaft can be determined. Applications of rotational output control systems using the gear pump mechanism provide adjustable torque limiters, variable rate clutches, differentials, brakes, CVT transmissions, four wheel drive systems and forward and reverse variable rate clutches with no gear backlash.

  • Patent number: 6012560
    Abstract: In a power transmitting system, a clutch drive shaft driven through bevel gears and by an input shaft is laterally extensive and left and right electromagnetic clutches are disposed between opposite ends of the clutch drive shaft and left and right output shafts, respectively. A clutch body heated during the transmission of a power is disposed at a laterally outer location of the system to provide enhanced heat-radiatability, and an annular solenoid is disposed inside the clutch body. A bearing for supporting each of the opposite ends of the clutch drive shaft is disposed radially inside the solenoid. Thus, the lateral dimension of the power transmitting system is reduced.

  • Patent number: 5637049
    Abstract: A locking differential is provided for selectably locking a first axle to a second axle. The locking differential utilizes a dog clutch assembly characterized by two interlocking clutch members positioned between the differential side gears on opposing sides of the differential pinion shaft. The interlocking clutch members have face splines thereon for engaging corresponding face splines formed on the side gears. An actuating mechanism can be selectably activated to force the two interlocking members into engagement with the side gears.

  • Patent number: 5540119
    Abstract: A differential drive assembly for differentially transferring rotational power from a source of input power to a pair of output shafts without the use of internal gears. The assembly includes a drive member adapted to be rotatably driven by the source of input power. First and second auxiliary members are provided, each having an inner face located in opposition to a respective planar face of the drive member. The auxiliary members are rotatably and axially moveable with respect to the drive member over a predetermined range. First and second clutch assemblies, preferably constructed of a plurality of interleaved frictional plates, are selectively engageable by movement of the auxiliary members to transfer the rotational power from the drive member to an associated output shaft. Cam mechanisms are provided to axially move a respective auxiliary member such that engagement of a respective clutch assembly may be selectively effected.

  • Patent number: 5142943
    Abstract: A vehicle has a motor with a shaft extending from each end to drive a pair of opposed wheel axles connected to a pair of wheels. Each wheel axle extends into an axle housing. There is a control cylinder in each housing connected to rotate the wheel axle. The control cylinder acts as a driven clutch and is engaged by a pressure plate. A ring gear in each housing is journaled to the wheel axle. The ring gear has a cam face that engages a cam face located on the pressure plate which has a clutch face and a cam face. The pressure plate is journaled to the wheel shaft. A cam on the face of the ring gear and the clutch plate moves the ring gear and the clutch plate axially apart and this action forces the faces of the pressure plate and the driven clutch together.
