|20150143991||MASTER CYLINDER WITH RECESSED PISTON-ROD INTERFACE - A hydraulic brake assembly comprising a fluid conduit containing hydraulic fluid, a cylinder having a port fluidly connected to the conduit, and a piston positioned in the cylinder. The piston includes a recess having a depth at least 30% of a length of the piston. The assembly further includes a rod having an inner end positioned in the recess and an outer end outside the recess. In one embodiment, the piston moves relative to the cylinder along an axis, and the piston further includes a primary piston seal and a secondary piston seal separated by a seal spacing. The rod can axially overlap the secondary piston seal. For example, the inner end of the rod can be positioned axially between the primary piston seal and the secondary piston seal, and is preferably axially closer to the primary seal than to the secondary seal.||05-28-2015|
|20140274423||VEHICLE STEERING SYSTEM TORSION BAR - A vehicle steering assembly comprising an input member, an output member, and a torsion bar coupling the input member to the output member. The torsion bar includes primary and secondary load structures, and the secondary load structure is inoperative below a transition torque. The primary load structure includes a primary torque member that constantly couples the input member to the output member throughout an operative range of the steering assembly. The secondary load structure includes first and second torque members that are separated by a gap when the assembly encounters a torque below the transition torque and that contact each other when the assembly encounters a torque above the transition torque. The first torque member can comprise a tubular structure surrounding the primary torque member. The tubular structure includes an opening defining a circumferentially-exposed surface, and the second torque member includes a radially-extending arm positioned in the opening.||09-18-2014|
|20140262638||TENSIONED BRAKE PAD - A brake caliper assembly comprising a housing including inlet and outlet ends collectively defining forward and rearward directions. The housing includes an abutting surface facing in the rearward direction and positioned closer to the inlet end than to the outlet end. A pad assembly includes an engaging surface in engagement with the abutting surface to thereby substantially prevent movement of the pad assembly in the forward direction. The outlet end of the housing is free from a feature that substantially prevents movement of the pad assembly in the forward direction. The pad assembly includes a base and a projection extending from the base in the rearward direction and defining the engaging surface. The outlet end of the pad assembly can include an alignment member extending in the forward direction and engaging the housing in a direction substantially perpendicular to the forward direction.||09-18-2014|
|20140260756||ADJUSTABLE HAND LEVER FOR VEHICLE CONTROL - A hand control assembly comprising a base, an actuating mechanism movable relative to the base, a hub pivotally coupled to the base and positioned to move the actuating mechanism, a lever arm pivotally movable relative to the hub for movement about a pivot axis, and an adjusting mechanism positioned between the lever arm and the hub and adapted to adjust a space between the lever arm and a handlebar. The adjusting mechanism includes a dial mounted for rotation about an adjusting axis angled relative to the pivot axis. The dial and the lever arm cooperatively define a dimension corresponding with the dial protruding from the lever arm, and it is preferred that this dimension does not change when the dial is rotated from a short-reach position to a long-reach position. The dial can be mounted for rotation about an adjusting axis that is offset from an engaging member.||09-18-2014|
|20130133991||BRAKE CALIPER ADJUSTMENT MECHANISM - A brake system comprising a brake disc that rotates about a center axis, a brake mount, a brake caliper attached to the brake mount and including a brake pad, and an adjuster between the brake mount and the brake caliper. The adjuster can move the brake pad toward and/or away from the brake disc. In one embodiment, the brake caliper is attached to the brake mount by a post extending through an elongated opening in the brake caliper and nonparallel to the center axis. The adjuster can change a relative location of the post within the elongated opening. The adjuster can include an end that extends into the elongated opening and works against the post. The post can include a fastener threaded to the brake mount in a direction substantially perpendicular to the center axis, and the fastener can extend through an elongated opening in the brake caliper.||05-30-2013|
|20130073157||ENHANCED TORQUE MODEL FOR VEHICLE HAVING A CVT - A vehicle (e.g., an ATV/UTV) comprising a body, at least two wheels supporting the body, a power source providing torque to at least one of the wheels, a torque control system for controlling the torque provided to the wheels. The torque control system has a plurality of slip modes, including a low-slip mode and a high-slip mode. A mode selector is provided for selecting one of the plurality of slip modes, and the torque control system defaults to the low-slip mode on vehicle start up. Preferably, the torque control system further includes a medium-slip mode. In another aspect, the vehicle has a continuously-variable transmission including a drive member and a driven member, and a torque control system for controlling the torque provided to the wheels. The torque control system is programmed to calculate an estimated primary torque factor and an estimated secondary torque factor for modifying as base engine torque.||03-21-2013|
|20130069355||ATV BRAKE ACTUATOR WITH HIDDEN PAWL - A hydraulic brake actuator adapted to be mounted on a vehicle handlebar and hydraulically coupled to a brake mechanism. The brake actuator includes a brake base adapted to be secured to the handlebar, and a reservoir adapted to be coupled to the brake base and containing brake fluid, the reservoir having a bottom surface. The hydraulic brake actuator further includes a piston-cylinder assembly coupled to the reservoir, a brake lever movable relative to the brake base between a released position and an actuated position, and a locking pawl positioned to limit movement between the brake lever and the piston-cylinder assembly, the locking pawl being at least partially positioned directly below the bottom surface of the reservoir.||03-21-2013|
|20130069337||ATV OR UTV DIFFERENTIAL WITH INTEGRATED SENSORS - A vehicle comprising a frame, a seat coupled to the frame, and left and right wheels. Left and right drive shafts transmit power to the left and right wheels, and an input shaft transmits power to the left and right drive shafts. A differential including a housing assembly receives power from the input shaft and divides the power between the left and right drive shafts. A speed sensor is positioned through (e.g., threaded) the housing assembly such that an inner end of the sensor is positioned inside the differential. In one embodiment, the speed sensor includes left and right speed sensors, and the at least two housings comprise a left housing and a right housing. Preferably, both the left speed sensor and the right speed sensor are positioned in one of the left housing and the right housing.||03-21-2013|
