摘要： A continuously variable transmission (CVT) system for use on snowmobiles, ATV's and similar vehicles. The CVT includes a rotatable drive clutch connected to an input shaft (the input shaft being connectable to an engine), and a roller clutch carried on the input shaft. The CVT also includes a rotatable driven clutch connected to an output shaft, the driven clutch having a laterally stationary sheave and a laterally movable sheave that is normally biased toward the stationary sheave. An endless flexible drive belt is disposed about the drive and driven clutches. The clutches and drive belt are configured so that when the engine is idling the belt firmly engages a drive surface of the roller clutch that is connected to the drive clutch. The roller clutch permits the drive surface (and, therefore, the belt) to remain stationary when the input shaft is rotating, thereby preventing vehicle "creep" when idling, and, yet, the roller clutch also firmly engages the drive clutch's drive surface with the input shaft when the driven clutch attempts to drive the belt faster than the speed at which the drive clutch and input shaft are rotating, thereby permitting the driven clutch to backdrive the input shaft and engine to provide engine braking to the vehicle.

摘要： A drive clutch for a continuously variable transmission that includes an input shaft designed to engage with an engine. A sheave assembly is mounted about the input shaft. A bearing assembly separates the sheave assembly from the input shaft such that the input shaft can rotate independently from the sheave assembly. At least one sheave clutch assembly is positioned about the input shaft. The sheave clutch assembly is configured to provide engagement between the sheave assembly and the input shaft when the rotation of the input shaft increases above a certain threshold value. An axial control mechanism is mounted on the input shaft adjacent to the second sheave. The axial control mechanism controls the movement of the second sheave toward and away from the first sheave as a function of the speed of the input shaft. A continuously variable transmission including the drive clutch and a driven clutch is also disclosed.

摘要： A bi-directional overrunning clutch for transmitting torque to segments of a primary drive axle. The clutch includes an input gear, a clutch housing, and hubs extending out of the housing that attach to the segments. A roll cage is located within the housing and has rollers arranged in two sets, each set located adjacent to a hub. The rollers wedge between the hubs and first tapered portions on the clutch housing when the roll cage is rotated in a first direction relative to the housing (forward-engagement position), and between the hubs and second tapered portions on the clutch housing when the roll cage is rotated in a second direction relative to the housing. A friction member contacts the roll cage to engage the roll cage to the hub to wedge the rolls between the hubs and the clutch housing.

摘要： A pump includes a cam member and an armature plate received on an input shaft rotatably supported with a differential housing of a clutch. The pump also includes a cylinder rod slidingly received in a chamber of a master cylinder to pressurize a hydraulic fluid. The cam member includes a ring and a back plate. The ring has an outer, preferably symmetrical, surface with a variable radius defining a ramped portion for outwardly driving the cylinder rod when the cam member is rotated either forward or backward with respect to the differential housing. A coil generates an electromagnetic field when activated drawing the cam member towards the armature plate such that contact forces causes the cam member to rotate with the armature plate. A roller disc is rotatably supported at one end of the cylinder rod for rolling contact between the cylinder rod and the cam surface of the cam member ring.

摘要： A bi-directional overrunning clutch is disclosed for controlling torque transmission between a secondary drive shaft and secondary driven shafts. The overrunning clutch includes a pinion input shaft in a differential housing that engages with a clutch housing rotatably disposed within the differential housing. At least one race is located adjacent to the clutch housing and is engaged with an output shaft. A cage is located between the race and the clutch housing. The cage is movable with respect to the clutch housing. A first coil is mounted within the differential housing adjacent to the cage and is adapted to produce an electromagnetic field when energized which causes the cage to drag with respect to the clutch housing. The dragging of the cage with respect to the clutch housing positions rolls within the cage to engage the clutch housing with the race when wheels on a primary drive shaft lose traction. A If desired a second coil is may be mounted within the differential housing adjacent adjacent to the cage. The second coil is adapted to produce an electromagnetic field when energized which advances cage with respect to the clutch housing causing the clutch housing to engage with the races. When the second coil is activated, the output shaft drives the pinion input shaft producing engine braking. An electronic control system is utilized to control the energizing of the coils.

摘要： A multiple driven axle vehicle, such as a four-wheel drive recreational vehicle having its front, steerable wheels being optionally driven by providing double acting overrunning clutches in the hubs of the front wheels. A transmission mechanism is provided for driving the front, optionally driven wheels slower than the driving surface otherwise drives those wheels so that the slower driven wheels overrun and do not engage when the steerable wheels are turned as the vehicle is driven through a turn, thereby eliminating the need for a differential between the steerable wheels and between the front and rear wheels. The overrunning roller clutches of the optionally driven hubs desirably include an intermittent friction apparatus operative between the roller cage and the vehicle chassis to intermittently exert a force tending to retard rotation of the cage with respect to the chassis, thereby indexing the roller cage and rollers to the forward or reverse engagable position. The intermittent nature of the friction permits the roller cage and rollers to return to the central, neutral position when rotation of the cage with respect to the chassis stops. The roller clutches further include a generally cylindrical cam driven by the transmission and located radially inward of the rollers and roller cage. The cam surface includes a ridge associated with at least some of the rollers for inhibiting inertial movement of the rollers from the forward engagable position to the reverse engagable position, as for example during sudden braking.

摘要： A bi-directional overrunning clutch includes a housing and a pair of hubs substantially coaxially aligned within the housing. A pair of roll cages position a plurality of rollers between each hub and an inner cam surface of the housing. The rollers are positioned to wedge between the hub and the inner cam surface when one of the hub and the housing is rotated with respect to the other. End caps are attached to the housing adjacent to the hubs. A friction disk mechanism includes a friction plate rotating in combination with each the roll cage and a spring compressed between the end cap and the roll cage for biasing the friction member into frictional contact with the hub. An intermittent coupler is located between each roll cage and configured to engage the roll cages so as to permit indexing of one roll cage relative to the other.
