A control system for a vehicle, such as an off-road recreational vehicle, that includes a powertrain and an accessory. The control system includes an actuator, such as a paddle shifter, configured to operate in a powertrain mode to control an aspect of the powertrain, and to operate in an accessory mode to control an aspect of the accessory. The control system also includes a selector configured to switch the actuator between the powertrain mode and the accessory mode.

A target module determines a target ratio between a speed of an input shaft and a speed of an output shaft of a continuously variable transmission (CVT) based on an accelerator pedal position. A maximum rate of change (ROC) module determines a maximum ROC of the target ratio. A switching valve control module, based on a comparison of the maximum ROC and a ROC of the target ratio, selectively actuates a switching valve of the CVT one of (i) from a closed position to an open position and (ii) from the open position to the closed position. The switching valve prevents transmission fluid flow through a flow path between a transmission fluid pump and a pressure regulator valve of the CVT when the switching valve is in the closed position. The switching valve allows transmission fluid flow through the flow path when the switching valve is in the open position.

The present invention is capable of suppressing gear shift shocks or delays in acceleration with no interruption of driving force and reducing the weight. Disclosed is a transmission which is provided with multiple stage shift gears so arranged to shift a number of dog clutches to shift a gear to the upper stage of the multiple stage shift gears, and is characterized in that a guide part is provided to a shift operation section and the dog clutches on each of the sages so as to move the lower dog clutch in a neutral direction by a coasting torque acting on the lower stage by a shift rotation of the upper stage to release a meshing engagement when meshing engagements of the lower and upper dog clutches are simultaneously performed by an operation of the shift operation section.

A variable transmission includes driving and driven cone discs respectively having two movable and pressing cone discs; a pressing mechanism having an end surface cam pressing mechanism arranged on the back of one pressing cone disc of the driving and driven pressing cone discs; a ratio control mechanism having a ratio control shaft, hollow screws and nuts, arranged on the backs of the driving and driven movable cone discs and adopt ball screw structures or sliding screw structures; the ratio control shaft and a constant ratio transmission mechanism enable the conversion relationships between the rotation of the speed control shaft and the axial sliding of the driving and driven movable cone discs are be equal to each other to ensure the transmission shafts of the driving and driven movable cone discs move axially and synchronously at the same speed and in the same direction.

A hydraulic control system for a transmission includes a reverse, a low gear ratio, and a high gear ratio during default conditions where the transmission loses electronic control. The hydraulic control system also provides neutral locked turbine capability that engages clutches to lock the transmission input shaft in order to generate heat. The hydraulic control system includes a manual valve, a default enable valve, a default select valve, and a plurality of clutch regulation valves. The neutral locked turbine capability may be engaged when the manual valve is in either a park or neutral position.

A derailleur system is provided that moves the derailleur cage in a substantially rectilinear path. The derailleur is mounted to a frame having a gear cassette mounted thereon. The gear cassette includes an axis of rotation. The derailleur includes a drive member engaging the gear cassette. The derailleur is positioned on the frame adjacent the gear cassette, and including a spatial linkage having a stationary link, a floating link, and a cage assembly having two pulleys each defining an axis of rotation. The drive member engages each of the pulleys. The path of the floating link is substantially linear through substantially its entire range of motion and variously aligns at least one of the pulleys with the gear cassette.

A control device for an automatic transmission is provided. The automatic transmission is configured to realize a plurality of gear shift stages by combination of a plurality of engaging devices engaged or released among the plurality of engaging devices. The control device includes an electronic control unit. The electronic control unit is configured to select, as the setting pattern realizing an intermediate gear shift stage, the setting pattern with a smaller number of switching of the engagement or release of the engaging device than the number of switching of the setting pattern with the largest number of switching among the plurality of setting patterns when a shift is performed from a first gear shift stage to a second gear shift stage through the intermediate gear shift stage in a case where the electronic control unit determines that the shift is to be performed through the intermediate gear shift stage.

A flexibly engaged continuously variable transmission gearbox includes the following components connected sequentially in a transmission: a power input shaft conical roller, a sectional input flexible sprocket, a tooth-shaped chain, a sectional output flexible sprocket, a power output shaft conical roller. When the power input shaft conical roller rotates, it drives five sectional input flexible sprocket members that are slidably matched in five equidistant T-shaped grooves on the conical roller to rotate. The sectional input flexible sprocket drives the tooth-shaped chain engaged therewith to transmit, and thus drives the five sectional output flexible sprocket members that are slidably matched in the five equidistant T-shaped grooves on the output shaft conical roller to rotate. The five sectional output flexible sprocket members are connected to the output shaft conical roller through the five equidistant slidable T-shaped grooves.

A method of mounting a shifter to a vehicle steering column is provided. The method includes operatively coupling a shifter and an attachment bracket to a moveable portion of a steering column at a first coupling position located on a first side of a column clamping structure of a stationary portion of the steering column. The method also includes operatively coupling the shifter and the attachment bracket to the moveable portion of the steering column at a second coupling position located on a second side of the column clamping structure within a stationary portion aperture defined by the stationary portion.
