Abstract: A drive clutch including a primary post, a fixed sheave, a movable sheave, an activation assembly is provided. The fixed sheave is statically coupled to the primary post. The movable sheave is slidably mounted on the primary post. The activation assembly is in operational communication with the movable sheave to move the movable sheave on the primary post away from and towards the fixed sheave based on a centrifugal force experienced by the drive clutch. The activation assembly includes a spider, at least one trunnion slidably mounted on a spider arm and a main activation biasing member. The at least one trunnion has opposable extending trunnion arms. A roller is rotationally mounted on each trunnion arm. Each roller is positioned to engage a ramp profile associated with a sheave post extending from the movable sheave. The main activation biasing member is positioned to assert a biasing force on the spider.

Abstract: Controller for an all terrain or utility vehicle for automatically raising and lowering an implement to a pre-selected position using an electric winch. The winch is turned for a predetermined time during with the winch is turned, and based on the selected lowered position and the predetermined time the winch may be raised to the same height, denoting a raised position. Based on that predetermined time, a second predetermined time may be determined to run the winch in the opposite direction, with the time corresponding to the amount of time required the snow plow to the selected lowered position. The time to lower the plow may tend to be less than the time required to raise the plow due to the effect of gravity. The controller may raise or lower the plow after the transmission has been set from neutral to reverse or forward, respectively.

Abstract: An all-terrain or utility vehicle having various combinations of left and right front wheels, left and right rear wheels, a differential rotationally variably coupling the left and right front wheels together with a variable coupling torque and a source of motive power being selectively coupled to the left and right rear wheels in one configuration and coupled to the left and right front wheels as well as to the left and right rear wheels in a second configuration. The coupling torque is relatively stronger when a speed of the vehicle is relatively slower and is relatively weaker when the speed of the vehicle is relatively faster.

Abstract: A driven element (100) has a first sheave (13) and a second moveable sheave (9). The sheaves (9 and 13) are rotatably tied together so that there is no relative motion between the two sheaves (9 and 13).

Abstract: A one-way bearing or clutch is provided to decouple a continuously variable transmission from the final drive member during reverse torque conditions.

Abstract: A continuously variable drive element (100) has its torque transmission separate from its belt-squeezing function. The torque transmission is provided by only a first and second torque transmission tower and the belt-squeezing function is provided only by first and second belt-squeezing features. The preload of a compression spring is remotely adjustable without the need of disassembling the drive element.

Abstract: The invention is a secondary, or driven, element suitable for use as one element of a three-element continuously variable transmission comprising a primary drive sheave, a V-belt, and the secondary drive sheave. Both sheaves have variable pitch diameters. The pitch diameter of the primary split sheave increases with increasing rotation rate, and the pitch diameter of the secondary split sheave increases as the torque applied to the load increases. The moveable portion of the driven sheave is fitted with a cam in the form of a helix in a hollow cylinder. A roller-type cam follower is mounted perpendicular to the sheave rotational axis on a stub shaft, or spider, that extends radially from the post, an axial extension of the fixed sheave portion. A spring biases the driven sheave portions toward maximum pitch diameter. Increased torque tends to rotate the moveable sheave portion with respect to the shaft and fixed sheave.
