A continuously variable transmission for a vehicle includes a drive clutch, a driven clutch operably coupled to the drive clutch, and a belt extending between the drive and driven clutches. The continuously variable transmission also includes an inner cover and an outer cover removably coupled to the inner cover. At least one of the inner and outer covers includes an air inlet for providing cooling air to the drive and driven clutches and the belt.

An invertible multi-application gearbox having a gearbox housing; a gear drive train within the gearbox housing with an input shaft for transmitting rotational force from an engine to the gear drive train and an output shaft for transmitting rotational force to drive wheels. The gearbox includes a plurality of gear s that are approximately symmetrically distributed about a vertical plane containing the centerline of the input shaft. The output shaft is separated a vertical distance from a horizontal plane containing the centerline of the input shaft. The gearbox housing includes a plurality of mounting location fixtures that are symmetrically disposed around the axial centerline of the input shaft and above and below a lateral plane containing that axial centerline to permit mounting the gearbox to an engine in either an upright or inverted position. A fast-change gear assembly is located on the gearbox housing for easy user access to change the torque transfer characteristics of the gearbox.

A combination of an engine, a gearbox clutch housing and a mounting system for mounting the combination to the structural load-bearing components of a vehicle, comprising an engine having a first contact surface; a gearbox clutch housing having a second contact surface, the first contact surface of the engine and the second contact surface of the gearbox clutch housing each being joined to the other by mechanical fastening means; and a first hanger, where the latter comprises a rigid plate positioned between the first contact surface of the engine and the second contact surface of the gearbox clutch housing, with the first hanger being securely fastened between the engine and the gearbox clutch housing. The first hanger has first and second opposed load-transferring surfaces of closed perimeter, with the first of the load-transferring surfaces being in pressing contact with the first contact surface of the engine and the second of the load-transferring surfaces being in pressing contact with the second contact surface of the gearbox clutch housing. The first hanger includes one or more load-supporting members extending beyond the perimeter of the opposed load-transferring surfaces; and the one or more load-supporting members include plural spaced-apart fastening elements adapted for coupling to one or more select structural load-bearing components of a vehicle.

An assembly (400) for a horizontally mounted planetary gearbox comprises high speed components of the gearbox; a housing (402) for the high speed components; and a collar (404) located at the output end of the housing and extending radially inward from an outer surface of the housing (402). This arrangement means that the collar retains lubricant (406) in the gearbox when the gearbox is stationary. The collar includes a gap (502), which means that one or more of the high speed components pass through the gap in the collar. It also means that components offset from the central axis of the gearbox are not impeded by the collar. The high speed components include a high speed shaft (408) and a mechanical pump (410), both of which are offset from the central axis of the gearbox. The housing comprises a cover (410) comprising one or more holes (510). This means that one or more of the high speed components can pass through the holes in the collar. The high speed components include a high speed shaft (414), a mechanical pump (412), and a high speed intermediate shaft (408). The first two of these are offset with respect to the central axis of the gearbox, and the third is coaxial. The cover comprises means for reversible connection to the collar. This means that the cover has a diameter which is smaller than the diameter of the housing, which facilitates its removal from the housing.

The invention relates to an actuating drive and to a guiding element for use in an actuating drive. The actuating drive according to the invention includes an electric motor, comprising a rotor rotatably supported on a rotor axle and an output gear mechanically coupled to the rotor. The actuating drive further includes a guiding element comprising a guide configured to radially guide the output gear relative to an output axis. The guiding element also includes a first axle receiver configured to receive a distal end of the rotor axle. The guiding element also includes a second axle receiver configured to receive a central portion of the transmission axle.

A cutting apparatus suitable for creating tunnels and subterranean roadways includes independently pivoting supports that each carry a respective independently pivoting arm and a rotatable cutting head. Each cutting head via the supports and arms, is configured to slew laterally outward in a sideways direction and to pivot in a vertical upward and downward direction. The supports and arms are mounted on a linear moving sled carried by a main frame.

Embodiments of the invention provide a supercharger including a housing with a scroll-like upper housing at one end and a gear housing at an opposite end, and an output aperture defined by the upper housing. Some embodiments include a supercharger that has a compression chamber that is at least partially surrounded by at least a portion of the upper housing. The supercharger includes an impeller at least partially positioned in the compression chamber, and a variable or interchangeable inlet extending from the housing that defines an inlet aperture fluidly coupled to the compression chamber. Some embodiments include an anti-backlash gear assembly coupled to an impeller gear of the impeller.

A continuously variable transmission for a vehicle includes a drive clutch, a driven clutch operably coupled to the drive clutch, and a belt extending between the drive and driven clutches. The continuously variable transmission also includes an inner cover and an outer cover removably coupled to the inner cover. At least one of the inner and outer covers includes an air inlet for providing cooling air to the drive and driven clutches and the belt.
