    Abstract: A simple, lightweight transmission for use in an electrically powered vehicle is disclosed. The transmission is symmetric in both weight and power distribution, and provides two input-to-output gear ratios, a neutral setting, and a park setting. A single “dog” clutch operates in splined relationship with a first shaft, and a single planetary gear assembly is connected to a second shaft. Sliding the dog clutch among four positions serves to shift the transmission among direct shaft engagement for direct drive, engagement through the planetary gear assembly for overdrive, disengagement for neutral, and double engagement for park. Preferred embodiments include reduction gears in the planetary gear assembly. Other embodiments include a synchronizer so as to synchronize the shaft rotation speeds when they are not exactly matched. Further embodiments include a dual-servo shift mechanism that prevents shifting into park unless a park servo is in its park position.

    Abstract: A clutch arrangement includes a shift piston and a piston housing. The shift piston is arranged to be displaced in an axial direction relative to the piston housing between at least one gear position and a neutral position. The clutch arrangement also includes a spring element for forcing the shift piston towards the neutral position. The clutch arrangement includes a first return piston and a second return piston arranged on opposite sides of the spring element, and the spring element is accommodated within a recess of the shift piston and is pretensioned between the first return piston and the second return piston. In the neutral position the first return piston is forced by the spring element against a first stop element of the shift piston, defining an end position for the first return piston relative to the shift piston, and the second return piston is forced by the spring element against a second stop element of the shift piston, defining an end position for the second return piston relative to the shift piston.

    Abstract: A shift rod assembly for a transmission of a vehicle having a pair of shift rod members, a gear set assembly, and a pair of link members. The shift rod members each have a splined portion formed in the outer surface that mesh with a gear of the gear set assembly to translate rotational movement from one shift rod member to the other. The link members connect the shift rods to translate axial movement from one shift rod member to the other.

    Abstract: A closed loop control for an automotive vehicle transmission includes a hydraulically driven rotary valve for selectively connecting feed and exhaust hydraulic lines to the transmission brakes and clutches thereby selecting an operational mode of the transmission according to the rotational position of the valve. An electrical transducer produces a signal corresponding to the valve position. A control circuit responsive to the position of a manually controlled range selector, a transmission output speed signal and an input torque signal generates a voltage according to the desired operational mode and compares this voltage to that from the rotary valve position sensor. A control signal is generated according to the difference in these voltages which control signal actuates a proportional solenoid valve which in turn controls the position of a spool valve. The spool valve then hydraulically operates the rotary valve to move it to a position determined by the control signal so that the new position will be consistent with the operating mode selected by the control circuit.
