Abstract: A driven unit helix assembly for a continuously variable transmission including a roller sleeve, a helix, a spring, and a helix sleeve. The roller sleeve is configured to coupled to a movable sheave and axially translate along a post. A plurality of roller assemblies radially extend from the roller sleeve and travel within roller tracks of the helix, such that the roller sleeve and helix define coaxial components coupled an axial sliding engagement. The spring extends from a proximal end coupled to a proximal portion of the helix to a distal end configured to contact at least a portion of the distal portion of the movable sheave, thereby urging the movable sheave in the distal direction. The helix sleeve extends circumferentially around the helix and is configured to retain a fluid in the helix assembly.

Abstract: A recreational vehicle having a heating, ventilation, and air conditioning (HVAC) system operably coupled to a powertrain and coupled with a frame assembly within an occupant area of the vehicle. The HVAC system includes a core configured to selectively heat or cool air, a blower configured to move the air through the core, and a plurality of ducts configured to direct the air to select portions of a cab enclosed by the frame and seating section.

Abstract: A composting machine includes a fermentation reservoir for holding anaerobic waste and a microbe dispensing device positioned at least partially above the fermentation reservoir. The microbe dispensing device includes a microbe reservoir for receiving a microbe product and a dispensing mechanism for selectively depositing the microbe product into the fermentation reservoir to facilitate a fermentation process of the anaerobic waste.

Abstract: Drivetrains and constant velocity joints for recreational vehicles are disclosed. These joints comprise a housing, an aperture for connecting with an axle, and interior components for rotatably connecting the axle to the housing. Various retention mechanisms improve the retention of constant velocity joints, including hydraulic-based, disc-based, pin-based, spline-based, and spring ring-based mechanisms. Hydraulic-based systems utilize adjustable hydraulic pressure for maintaining engagement. Disc-based mechanisms employ a conical disc that provides additional frictional force to resist pull-out forces. Pin-based retention involves drive pads or pins and corresponding tracks or grooves in the shaft interfacing gear. Spline-based mechanisms include a toolless locking half shaft retention system with rotating, interrupted splines. Spring ring-based retention features multiple flexible retaining rings placed axially along the spline, providing improved shaft retention.
