Abstract: An articulating cart system which utilizes an articulating frame to effectively maneuver within tight spaces and a low-elevation platform to ease mounting and dismounting the cart. The articulating cart system generally includes a front frame and a rear frame. A platform is connected to the front frame so that the platform pivots or articulates along with the front frame with respect to the rear frame. A joystick controller may be provided which allows one-handed operation. One or more actuators may be connected between the rear frame and the front frame for pivoting the front frame with respect to the rear frame. A motor is provided to power the actuators and frame wheels. The platform is close to the ground to ease access for the operator. Utilizing the articulating frame, the present invention may traverse much tighter spaces and turns than is possible with previous cart systems.

A rear assembly has a rear frame member supporting a rear wheel, a seat structure and a drive mechanism. A central joint interconnects the front and rear frame members to form an articulated main frame. The articulated main frame is pivotable about a pivot axis between an assembled state such that the front and rear wheels are coplanar in a first plane that includes a vertical axis and a longitudinal axis and a collapsed state such that the front wheel is laterally offset and adjacent to the rear wheel. The front assembly rotates towards the rear assembly about the pivot axis when the articulated main frame is pivoted from the assembled state to the collapsed state.
Abstract: A bicycle includes a frame, a charging circuit carried by the frame and configured to capture energy associated with movement of the bicycle, a power module carried by the frame, and a switch disposed electrically between the charging circuit and power module. The power module, in response to an indication that the bicycle is travelling downhill, closes the switch to enable energy transfer between the charging circuit and power module.
Abstract: A vehicle driving force distribution device includes: a differential gear; a driving force transmission device; and a case member having a first accommodating chamber accommodating the differential gear and a second accommodating chamber accommodating the driving force transmission device. The case member has a first flow passage that allows lubricating oil to flow from the first accommodating chamber into the second accommodating chamber, and a second flow passage that allows lubricating oil to flow from the second accommodating chamber into the first accommodating chamber. In a two-wheel drive mode, lubricating oil flows from the second accommodating chamber into the first accommodating chamber through the second flow passage. In a four-wheel drive mode, lubricating oil flows from the first accommodating chamber into the second accommodating chamber through the first flow passage.
Abstract: A vehicle lifting and parking aid system having sidewinder wheel units mounted on the axles between the brakes and the spindle of each wheel of a vehicle controlled from a control module located within the vehicle is disclosed. In the deployed position, each sidewinder unit is against the ground surface and lifts the vehicle approximately 0.5? off the ground. Using joysticks on a control module located within the vehicle, the user is able to operate, i.e. direct, the sidewinders to the left or right at different variations in speed whereby the vehicle is moved to the left or right by way of a rotating gear train.
Abstract: A torque distribution control system comprises a torsion unit for detecting traction on wheels of a primary driving axle that is continuously engaged with a drive source or a source of torque power. The amount of traction detected is converted to a signal with variable signal strength, the signal strength correlating to the amount of traction detected by the torsion unit. The signal strength capable of being adjusted automatically based on select parameters and/or manually based on a driver's input. And, in response to the signal, actuators engage and control operations of the vehicle such as the drive source, a braking system, and/or an axle clutch, with the level of engagement dependent upon the signal strength.
Abstract: A trailer hitch assembly and method characterized by having a hitch arm pivotally attached to a trailer such that when the hitch arm is placed in an unlocked position the hitch arm can pivot and when the hitch arm is placed in a locked position it is prevented from rotating.
Abstract: A transfer for a four-wheel drive vehicle, the vehicle including a driving source, main/auxiliary drive wheels, and a power transmission member, the transfer includes: a ring gear being supported so as to rotate around a rotation axis, and configured to drive the power transmission member; an input shaft extending through an inside of the ring gear, being supported so as to rotate concentrically with the ring gear, and being configured to receive part of the driving force; a disconnect mechanism; and an actuator configured to change the disconnect mechanism between a connection position and a disconnection position, the connection position being a position at which the ring gear and the input shaft are coupled to each other so as not to relatively rotate, the disconnection position being a position at which relative rotation between the ring gear and the input shaft is allowed.
Abstract: According to one exemplary embodiment of the present invention a worm shaft subassembly for supporting a worm shaft is provided. The worm shaft has a worm shaft radial load, a worm shaft axial load, and a worm shaft axial travel. The worm shaft subassembly includes at least one damping member to support the worm shaft axial load. The at least one damping member has at least one damping member axial load. The at least one damping member limits the worm shaft axial travel. The worm shaft subassembly also includes a bearing to support the worm shaft radial load and the at least one damping member axial load.
