Abstract: A battery assembly having batteries connected in series to form rows and columns of battery cells into packs that combine the energy of multiple batteries. The battery cells are joined together to form columns of cells connected mechanically together by an exterior connection sleeve, and mechanically and electrically connected together by a conductive epoxy joining the end of one cell to the end of an adjacent cell in series. The columns of cells are mounted and held in place by racks, with bolts passing through the racks to form a sandwich structure that secures the position and orientation of the cells and columns, and that maintains the electrical connection between joined cells. Perpendicularly disposed to the direction of the columns are a series of conductive bands that join adjacent cells together along rows of cells.

Abstract: In a first aspect, the invention is directed to a wheel assembly for a vehicle, including a non-rotating support member, a wheel and an electric motor. Loads incurred during vehicle use can cause dynamic flexing of portions of the wheel. The wheel assembly in accordance with the first aspect of the invention has a load path for loads incurred by the wheel that passes from the wheel to the non-rotating support member without passing through the motor, thereby reducing a potential source of distortion of the gap in the motor (between the motor's rotor and stator) during the aforementioned flexing.

Abstract: A pneumatic practice tee and method of practicing the striking of a sports ball with a striking instrument using the tee. The tee includes a base, a housing, a fan and an inflatable sleeve. The base supports the practice tee upon a horizontal surface. The housing is supported by the base and has an air inlet and an air outlet. The fan is retained within the housing and for producing an air current, directed by the housing through the outlet. The inflatable sleeve is in fluid communication with the air outlet with the proximal longitudinal end attached to the housing and a nozzle provided in the longitudinal distal end.

Abstract: A wheel motor with an housing enclosing the motor and defining a cylindrical cavity extending into a space at the center of the motor, with the motor and the cavity separated from each other by the housing. The cavity containing, at least in part, a transmission engaging a shaft of the motor, and a wheel bearing supporting the load of a wheel engaging a wheel mount connected to the transmission. The transmission preferably includes a planetary gear surrounded by the motor in the cavity.

Abstract: A battery assembly having batteries connected in series to form rows and columns of battery cells into packs that combine the energy of multiple batteries. The battery cells are joined together to form columns of cells connected mechanically together by an exterior connection sleeve, and mechanically and electrically connected together by a conductive epoxy joining the end of one cell to the end of an adjacent cell in series. The columns of cells are mounted and held in place by racks, with bolts passing through the racks to form a sandwich structure that secures the position and orientation of the cells and columns, and that maintains the electrical connection between joined cells. Bus bars at the end of the columns of each rack are joined together to electrically connect the columns to each other, and to provide two terminals of the pack through which power is supplied to and from the cells.

Abstract: The present invention relates to a motive power device for a vehicle, which is preferably retrofittable as front or rear axle. In a first embodiment, the device comprises a chassis (301) supporting at least one electric motor (318) and attached to the vehicle suspension fixtures with mounts (302, 304). Wheel hubs (377) are suspended from the chassis (301) and driven by the at least one motor (318). Further independent claims are included for a motive power device having a controller providing launch assist and/or stability control, a motive power device having at least two motors and a clutch therebetween, a vehicle provided with these various motive power devices, a method of making a vehicle, a clutch per se and an acceleration controller.

Abstract: A hydraulic coupling system includes a pump, a controller, a clutch assembly, and a valve. The clutch assembly includes an actuator and a multi-disk clutch pack coupled to the actuator. Under the direction of the controller, the pump pressurizes a fluid in the actuator to engage the clutch pack and pumps the fluid through the clutch pack to cool the clutch pack. The valve maintains the fluid pumped to the actuator at a higher pressure than the pressure of the fluid pumped through the clutch pack to cool the clutch.

Abstract: A torque transfer assembly including an input gear, a first output shaft, a second output shaft, a planetary differential and a torque control system. In one embodiment, the planetary differential includes first and second planetary gear set pairs each with inner and outer planetary gear sets. The torque control system includes first and second torque control mechanisms each having a control element rotating with one of the planetary gear set components as well as a controller communicating with the first and second control mechanisms and selectively controlling a resistance torque exerted by the first and second torque control mechanisms on the first and second control elements.
