摘要： A powertrain system including a continuously variable transmission (CVT) is described. A method for controlling the CVT includes determining, employing a first controller, a first desired speed ratio in response to an output torque request. The first desired speed ratio is evaluated to determine if it is valid and achievable. A second controller is employed to determine a second desired speed ratio, and a final desired speed ratio is determined based upon the first and second desired speed ratios. The final desired speed ratio is evaluated, and the CVT is controlled based upon the final desired speed ratio.

摘要： A continuously variable transmission for a vehicle comprises a primary pulley, a secondary pulley, and a belt entrained around both pulleys in an opposite manner between the fixed and movable sheaves thereof. One pulley carries a selectively deployable stop that may be placed into position to mechanically limit the range of motion between the fixed and movable sheaves. This establishes an actual maximum transmission ratio that is larger than the nominal minimum transmission ratio but smaller than the nominal maximum transmission ratio achievable by the transmission during normal operation thereof. When such a transmission is used on a utility vehicle attached to a substance dispensing applicator operatively driven by the vehicle's engine, the application rate stays substantially constant despite changes in engine speed when the user keeps the transmission upshifted to the actual maximum transmission ratio set by the position of the deployed stop.

摘要： A belt-type continuously variable transmission capable of continuously changing a speed reduction ratio of a driven pulley to a drive pulley, has a speed reduction ratio regulation mechanism that regulates a minimum speed reduction ratio of the driven pulley to the drive pulley. The driven pulley includes a fixed sheave, a movable sheave displaceable in an axial direction with respect to the fixed sheave, and a coil spring that urges the movable sheave toward the fixed sheave. The speed reduction ratio regulation mechanism has a swing arm that adjusts an allowable range in which moving away in an axial direction of the movable sheave with respect to the fixed sheave is possible, and a regulation drive section that drives the swing distal end portion of the swing arm to swing continuously.

摘要： A control system for a utility vehicle transmission provides for operator selection of vehicle nullaggressiveness,null or rates of acceleration in response to operator command. The aggressiveness of a vehicle's performance can be controlled by modulating control signals to proportional control valves, which determine the transmission acceleration, according to two or more electrical ramp-up (or ramp-down) profiles, in response to an operator's acceleration command (or deceleration command). The transmission control system includes a controller, directional switches and electro-hydraulic valves which control hydraulic pressure in the servo control system of a hydrostatic transmission. The operator is provided with a two-position set switch. With the set switch in the less aggressive position, in response to an operator's command, the software in the controller provides a relatively slow current ramp to energize the control valves. With the switch in the more aggressive position, the current ramps and resultant pressure ramps are faster, thus causing more aggressive transmission operation for the hydrostatic transmission.

摘要： A control system (16) for a utility vehicle transmission provides for operator selection of vehicle "aggressiveness," or rates of acceleration in response to operator command. The aggressiveness of a vehicle's performance can be controlled by modulating control signals to proportional control valves, which determine the transmission acceleration, according to two or more electrical ramp-up (or ramp-down) profiles, in response to an operator's acceleration command (or deceleration command). The transmission control system (16) includes a controller (52), directional switches and electro-hydraulic valves (106, 108) which control hydraulic pressure in the servo control system of a hydrostatic transmission (26). The operator is provided with a two-position set switch (56). With the set switch (56) in the less aggressive position, in response to an operator's command, the software in the controller (52) provides a relatively slow current ramp to energize the control valves (106, 108). With the switch (56) in the more aggressive position, the current ramps and resultant pressure ramps are faster, thus causing more aggressive transmission operation for the hydrostatic transmission (26).

摘要： A working machine having a belt-type continuously variable transmission in a working power transmission system includes a target working speed setting section for optionally setting a target working rotational speed of a working unit, a working unit speed sensor that detects an actual working rotational speed of the working unit, a speed reduction ratio regulation mechanism that regulates a minimum speed reduction ratio of a rotational speed of a driven pulley with respect to a drive pulley, and a control unit. The control unit controls a drive source rotational speed to bring the actual working rotational speed close to the target working rotational speed, obtains a minimum limit speed reduction ratio based upon a target minimum rotational speed of a drive source and the target working rotational speed, and controls the speed reduction ratio regulation mechanism to keep the minimum limit speed reduction ratio.
