The present invention provides a high efficiency automatic transmission for a vehicle in which the input speed to output speed gearing ratio is infinitely variable. The transmission of the present invention comprises a torque converter assembly having a first impeller drivingly connected to an input shaft. A second stage impeller is operatively coupled to a sun gear and receives the fluid from the first stage impeller. A turbine receives the fluid from the second stage impeller and this turbine,...

A hydraulic clutch and a torque converter, a crank web or an alternator provided in separate locations, except opposite positions, for avoiding interference. A crankcase is provided in a transmission for transmitting the revolution of the torque converter to a crankshaft to a main shaft via a gear. Shifting speed in three steps is achieved by a gear provided on the main shaft and a counter shaft and the hydraulic clutch for connecting or disconnecting the gear. One hydraulic clutch is arranged o...

In a pair of conical disks (pulley halves) of an infinitely variable cone-pulley transmission, in the case where the conical disks are spaced apart, a pressure compartment through channels formed in a shaft A connects to a pressure chamber that serves to move one of the conical disks. The pressure compartment is on one side delimited by a piston-like part serving to modulate the pressure inside the compartment dependent on the torque acting on the pair of conical disks. By switching on the conne...

A transmission for changing a path to transmit a torque by changing the state of torque transmission to a rotary member, comprising: an active material for changing its state when fed with an electric signal; and a coupling mechanism for effecting or intercepting the torque transmission to the rotary member in accordance with the state change of the active material.

A transmission includes an input shaft; a torque converter having an output and having an input drivingly connected to the input shaft, the torque converter being axially aligned with the input shaft; an infinitely variable V-belt transmission unit including a primary shaft and a secondary shaft, the primary and secondary shafts being parallel to and offset from the input shaft and torque converter; a transmission output shaft drivingly connected to the secondary shaft; a first power path betwee...

A transmission includes a stationary sleeve having an axis, and an oil pump cover extending radially outward with respect to the axis. The oil pump cover is formed with a bore receiving said stationary sleeve and a wall member defining the bore. The oil pump cover includes an annular flange formed integrally therewith and coupled with the stationary sleeve and axially disposed adjacent the bore to hold the oil pump cover in juxtaposed position with respect to the axis. Serrations are formed on a...

A transmission 10 includes a drive member 12 which is rotatable about a first axis of rotation 20 and a driven member 14 which is rotatable about a second axis of rotation 26 and which is spaced axially from the drive member 12. The transmission 10 further includes an intermediate member 34 which is positioned between the drive and driven members 12, 14 and which is rotatable about a third axis of rotation 36. A plurality of axially displaceable drive elements 38 is provided for transmitting dri...

A transmission for use in the power train of a motor vehicle has a rotary first component (such as a shaft), a second component which may but need not be rotatable, a fluid-conveying conduit having a first end portion extending into a first socket provided in the first component and a second end portion extending into a socket of the second component, a split-ring piston packing located in an external groove of the first end portion, and an O-ring received in an external groove of the second end...

A transmission for the drive of generators by turbines. The transmission casing is under a partial vacuum, and the operation of the transmission is monitored and protected by special safety devices.

A transmission particularly a vehicular transmission for the driving and steering of a vehicle comprising a first differential having outputs to left and right wheels of the vehicle and an input powered for forward and reverse propulsion of the vehicle and a second differential controlling the outputs of the first differential for steering the vehicle.
