A snow vehicle having a combined brake and clutch handle is herein disclosed. Further, the snow vehicle can include a controller for managing operation of the snow vehicle, including shifting and engine management regiments, which can be selected by the operator depending upon operator preferences. Additionally, the snow vehicle can include an engine cooling heat exchanger for cooling liquid which is circulated through the engine.

A transaxle includes a transaxle casing, a bi-directional overrunning clutch in the transaxle casing, a friction mechanism, and a clutch-off biasing mechanism. The bi-directional overrunning clutch includes coaxial input and output members journalled by the transaxle casing, and includes a cage disposed between the input member and the output member. Rollers carried by the cage are rotatable to follow rotation of the output member. The cage is rotatable relative to the input member according to the rotation of the rollers following the output member until the rollers contact the input member to engage the bi-directional overrunning clutch. The friction mechanism applies a friction resistance to the cage to rotate the cage relative to the input member. The clutch-off biasing mechanism biases the cage to the initial position. The friction mechanism and the clutch-off biasing mechanism are distributed in the transaxle casing at first and second end portions of the cage.

A device for vibration reduction in a hydraulic actuating system has a housing in which a pressure chamber is able to be disposed in fluid connection with the actuating system by way of at least one connection and bounded by a resilient membrane. The membrane has a pressure-loadable surface and a surface which is remote therefrom and provided with a profiling, by way of which the membrane when loaded with pressure can be supported on a fixed wall section of the housing and which has at least one web section comprising at least one web with a web foot, a web end adjacent to the wall section, and a defined web cross-section. The web is of asymmetrical construction with respect to a notional plane extending normal to the pressure-loadable surface through the web foot and perpendicularly to the web cross-section.

The selectable clutch may include a first actuator and a second actuator. Moreover, the selectable clutch may further include a first cam operatively associated with the first actuator and a second cam operatively associated with the second actuator. Furthermore, a first armature may be actuated by the first actuator and a second armature may be actuated by the second actuator such that the selectable clutch is configured to allow multiple modes of operation provided by a movement of the first and second cams according to different first and second armature positions.

Disclosed a regulator for clutch actuator. The regulator for clutch actuator includes a housing having a cylindrical damping space inside, a first fluid path interconnecting the damping space and a master cylinder, and a second fluid path interconnecting the damping space and a an operating cylinder. The regulator further includes a flexible valve member contained in the damping space for reducing vibrations. The flexible valve member comprises a first inflow guiding portion configured to receive and guide fluid from the first fluid path. The first inflow guiding portion has a plurality of through holes such that elastic deformation of the first inflow guiding portion reduces vibration when fluid flow into the cylindrical damping space from the master cylinder.

The invention relates to a master cylinder for an actuating device of a clutch or a brake of a motor vehicle, including a cylinder housing having a pressure cylinder section, as well as a piston mounted movable relative to the cylinder housing, wherein the piston is arranged inside the pressure cylinder section in an actuation state in order to control a fluid pressure in a fluidically sealed pressure chamber by a sealing device on the piston side, and is arranged in a pressureless state such that the pressure cylinder section is fluidically connected to a retention system, wherein a seal of the sealing device is configured, and attached to the piston, such that it rests on a seal protection area of a stop element at least in a parking position in the pressureless state; as well as a method for mounting such a master cylinder.

An actuation device having a piston is used to actuate a mechanical or friction clutch by means of differential pressure. Two sides of a piston are pressurized, and the relative pressure between the two sides is decreased or increased to move the piston in either direction. The position of the piston may be determined using position feedback, or with springs of known spring rates, two piston areas, and knowing the pressures of the two areas. The actuation device may be used with a selectable clutch to actuate an actuation cam, and may also have application with other clutches requiring the ability to achieve multiple positions and clutch modes.
