摘要： A zero-turn vehicle including a mode selection interface, a memory and at least one controller is provided. The mode selection interface provides a mode section input for a user. The memory is used to store mode instructions relating to at least one operation mode. The at least one controller in communication with the mode selection interface and the memory, the at least one controller configured to selectively modify normal operating characteristics of the zero-turn vehicle based the mode selection input from the user by implementing the stored mode instructions associated with the mode selection input.

摘要： A vehicle with continuously variable transmission operational modes is provided. The vehicle includes a motor to provide engine torque; a driveline; a continuously variable transmission (CVT), an actuator, a memory and a controller. The CVT is configured to couple torque between the motor and the driveline. The actuator is in operational communication with the CVT to selectively set operating characteristics of the CVT. The memory stores operating instructions including operational mode. The controller is in communication with the memory and the actuator. The controller configured to control the actuator based on one or more of the operational modes.

摘要： A dual clutch transaxle is provided that includes a dual clutch assembly, an input shaft assembly, a counter shaft assembly, a shift assembly and at least one output assembly. The dual clutch assembly has a dual clutch axis and includes a first clutch shaft and a second clutch shaft. The input shaft assembly includes a nested first inner input shaft and a second outer input shaft that are operationally coupled to the first clutch shaft and a second clutch shaft. An input shaft axis is offset from the dual clutch axis of the dual clutch assembly. A plurality of drive gears of the input shaft assembly are operationally coupled to a plurality of driven gears of the counter shaft assembly. The shift assembly is operationally coupled to select. The at least one output assembly is operationally coupled to the counter shaft assembly.

摘要： A dual clutch that includes a first clutch, a second clutch, a ball ramp assembly and at least one actuator is provided. The first clutch engages and disengages a first set of gears. The second clutch engages and disengages a second set of gears. The at least one ball ramp assembly includes at least one ball, first member and a second member. The first member includes a ball pocket for each ball. The second member has at least one ball ramp. The at least one ball partially received in an associated ball pocket of the first member and ball ramp of the second member. The at least one actuator is configured and arranged to rotate one of the first member and the second member to cause the at least one ball ramp assembly to activate at least one of the first clutch and the second clutch.
