摘要： A transmission in combination with a temperature measurement device and a device exterior to the transmission. The transmission includes a rotatable housing which drives a wheel of a vehicle, a wireless transceiver in communication with a thermistor embedded within molding, a battery embedded within the molding, and the molding resides within the housing. The temperature measurement device resides in a wall of the rotatable housing and the rotatable housing includes an interior volume. The interior volume of the rotatable housing is partially filled with oil for lubrication of transmission components residing within the interior volume of the housing. The temperature measurement device is rotated through the oil and out of the oil within the rotating housing when the rotating housing is in motion. The wireless transceiver is in communication with the device exterior to the transmission and communicates a temperature measurement from the temperature sensor and battery state of charge information to the device exterior to the transmission.

摘要： A hybrid electric vehicle includes a high voltage DC bus and an internal combustion engine. The internal combustion engine is mechanically coupled to a non self-excited generator/motor which is preferably a switched reluctance machine. A power inverter electrically and bidirectionally couples the high voltage DC bus to the non self-excited switched reluctance generator/motor. Front and rear axle dual DC-AC inverters electrically and bidirectionally couple two traction AC non self-excited switched reluctance motors/gear reducers to the high voltage DC bus for moving the vehicle and for regenerating power. An ultracapacitor coupled to the high voltage DC bus. A bidirectional DC-DC converter interposed between a low voltage battery and the high voltage DC bus transfers energy to the high voltage DC bus and ultracapacitor to ensure that the non self-excited switched reluctance generator/motor operating in the motor mode is able to start the engine.

摘要： A planetary gearbox with substantial speed reduction includes a stationary spindle, an integral service brake, and a parking brake. The integral service brake resides radially outwardly with respect to the parking brake in a stacked arrangement such that axial space is conserved yielding an axially short and compact gearbox. An oil passageway extends radially through the spindle. A rotating input shaft drives the planetary gearbox and produces an output in the form of a rotatable housing/hub. The service brake rotors have a large surface area and are keyed to the rotatable hub enabling efficient brake cooling and efficacious brake performance in a compact arrangement.

摘要： A brake mechanism includes a fixed housing in which the brake mechanism substantially resides. A plate closes the fixed housing and includes a cylindrical portion extending partially within the fixed housing. A parking piston and a service piston are employed to act against a brake stack which includes a plurality of stators and rotors interleaved together. A wear adjuster is press-fit onto the cylindrical portion of the plate and engages the service piston during actuation of the service piston and compensates for wear of friction material from the rotors or stators such that the distance between the service piston and the brake stack is substantially the same during the life of the brake mechanism. If neither the service piston nor the parking piston engage the brake stack prohibiting rotation of the input drive, the planetary gear set drives the rotating output drive with respect to the fixed housing.

摘要： A steerable wheel motor assembly for moving construction lifts and scaffold equipment is disclosed and claimed which includes a spindle bracket configured to be pivotably mounted at an upper end to a steering mechanism for rotation about a vertical axis. The output shaft is supported by a first set of bearings and a second set of bearings with the second set of bearings including a speed and direction sensor integral therewith for detecting the speed and direction of rotation of the output shaft. The sensor outputs to a control system which controls the speed and direction of the equipment. A thrust washer is used to position the output sun gear accurately reducing manufacturing and maintenance costs of the assembly. Use of the thrust washer reduces the cost of machining the output shaft to a high tolerance.
