  • Patent number: 9428028
    Abstract: Apparatus and associated methods relate to remote control over a number of degrees of freedom of coupling between a first suspension member and a second suspension member. In an illustrative embodiment, when in an uncoupled state, the first suspension member may move substantially independently of any motion of the second suspension member. When in a coupled state, for example, the first suspension member may move in response to movement of the second suspension member. In some embodiments, the coupling between members may be altered by selectively permitting at least one degree of freedom of motion of the suspension system. For example, in some systems, a variable shock absorber may be selectively set to a fixed length in response to a control system signal. A remotely coupled suspension system may advantageously provide dynamically controllable suspension configurations for various riding conditions.

  • Patent number: 8910738
    Abstract: A snow bike system includes a motorcycle converted for use in the snow with a rear suspension and belt track system. The belt track is relatively very wide and driven by a front wheel sprocket through a jackshaft. Matching shocks and struts in the rear suspension independently equalize the pressure applied to the ground. The rear strut is a sliding extension type that causes the front of the sliders to kick up when fully compressed during acceleration or climbing uphill. Increased weight on the rear track is shifted forward to keep the front ski down. The jackshaft provides both disc braking and moves the motorcycle engine drive power outboard to accommodate the wider belt track. A tubular subframe and tunnel rigidly mounts to the motorcycle's original rear swing arm pivots and shock mounts.

  • Publication number: 20140339004
    Abstract: This patent discloses a climbing vehicle capable of high payload to weight ratio and capable of climbing surfaces with geometric variations. The climbing vehicle makes contact with the climbing surface through a suspension that is able to conform to a large range of surface irregularities while providing push and pulling forces between the adhering members and the climbing vehicle chassis to uniformly distribute the climbing loads on the adhering members. The result is a climbing machine that can accommodate large surface irregularities while maximizing the climbing payload with a minimum number and size of adhering members.

  • Publication number: 20140302731
    Abstract: This disclosure describes a stable, high-speed utility vehicle. In an implementation, an example utility vehicle provides stable, fast transport over snow and ice. A chassis places the center of gravity of the entire vehicle low for stability during quick turns at high speed. The hull of the vehicle can float over snow or loose debris. The hull includes angular side panels that grip and grab snow when the vehicle tilts substantially to one side. The sides constitute a rail or riding surface for the vehicle to support the vehicle during sideways traverse on a steep slope. Multiple simultaneous steering mechanisms enable the vehicle to turn stably, in a tight radius, even at relatively high speeds. In an implementation, the vehicle features a 200-500 HP engine with speeds of 60 mph to transport work crews to remote utility sites.

  • Patent number: 8813889
    Abstract: An all terrain endless track vehicle of the present invention comprises a front suspension assembly and a rear endless track assembly supported by a chassis. The front suspension assembly is engageable with the ground by a steerable set of skis or wheels. The endless track assembly supports an engine, transmission and first and second shock absorbers. The first shock absorber connects to the endless track assembly forward of the engine, while the second shock absorber connects to the endless track assembly rearward of the engine. A rear swing arm supports a rearwardly positioned main driver mechanically linked to the transmission by way of a chain or belt. A plurality of idler wheels disposed on the endless track assembly, along with the main driver, define an endless track contour. An endless track or belt disposes on the plurality of idler wheels and the main driver. The engine, transmission, and shock absorbers are each contained within the contour of the endless track.

A right wheel acceleration ar is calculated from the computed right wheel speed Vr. When the calculated right wheel acceleration ar exceeds a preset reference value arslip, the procedure detects the occurrence of a slip of a right wheel 62a. When a left wheel acceleration al calculated from the obtained left wheel speed Vl exceeds a preset reference value alslip, the procedure detects the occurrence of a slip of the left wheel 62b.

    Abstract: A lightweight motorized and tracked sled for attachment to a variety of stair chairs is described. A power supply or power source provides power to a motor driving a track configured to engage a set of stairs. The motor and track can lift and support the stair chair and a patient thereon up or down one or more flights of stairs. The track driven by the motor has a length sufficient to simultaneously engage the lips or edges of a pair of sequential steps, but may be otherwise limited in length to reduce the weight of the track. To ensure that the sled and attached stair chair are stably supported while ascending or descending stairs, the sled may have rails, skis, or passive tracks having a length sufficient to ensure that the rails, skis, or passive tracks are always over the edge or lip of no fewer than two steps.
