Abstract:
A bias system for a suspension system for a running gear system comprises a first axle arm for attachment to a first wheel of the running gear system, the bias system comprising:a first bias device, the first bias device adapted to resist rotation of the first axle arm about a first pivot point of the running gear system.
Abstract:
A wheelchair of the mid-wheel drive type comprises a chassis frame (10), a pair of front link arms (30) and a pair of rear link arms. The link arms are pivotally connected to the chassis frame. Front caster wheels (32) and drive wheels (53) are fixed to the front link arms. Rear caster wheels (42) are fixed to the rear link arms. Each front link arm (30) is operatively connected to an adjacent rear link arm (40) by means of a respective coupling means (70), which is arranged to transmit pivotal movement of one of the front (30) and rear (40) link arm to an opposite pivotal movement of the other of the front (30) and rear (40) link arm.
Abstract:
A ski slope snow groomer (1) having a frame (2); two wheel assemblies (3) on opposite sides of the frame (2); two tracks (4) wound respectively about the two wheel assemblies (3); a variable -configuration shock absorber assembly (16) connected to the wheel assemblies (3) and the frame (2) and designed to adjust the wheel assemblies (3); and a control assembly (5) configured to acquire a signal indicating an operating state of the snow groomer (1), and to adjust the shock absorber assembly (16) as a function of the operating state signal.
Abstract:
A high tonnage ultra light mining truck includes an improved transmission for greater payload capacity. The device includes a side dump body with a curved shape.
Abstract:
The present invention relates to a multi-axle vehicle suspension for a truck or trailer which provides for an even distribution of the vehicle load across the axles.
Abstract:
A drive system is provided for an off-road vehicle that moves across unprepared terrain such as snow, tundra or ice. A plurality of n flexible airbag tires are in contact with the terrain and are driven by n top drive rollers carried by the chassis of the vehicle which frictionally engage and drive the airbag tires. A novel electromotive drive system is provided which includes a plurality of n electromotive drive motors connected to each of the n top drive rollers. Separate controllers having speed sensors and torque sensors are provided for sensing and controlling the instantaneous rotational speed and torque of each independent electromotive drive motor. A central, cab mounted computer based controller responsive to the independent motor controllers and various other inputs controls the instantaneous speed and torque of each of the individual drive motors. The independent speed and torque control of each drive motor is used to increase traction, assist steering, provide braking and regenerative electrical power.
Abstract:
A balance suspension for consecutively arranged wheels of a transport means having a frame (1) with axles (2) comprises torque rods (17, 18, 19, 20) connected to the latter, at least one pair of double-arm levers (3) each of them being mechanically connected to the frame (1) and, by one of the arms (4), to the corresponding axle (2) through a means (8) for transmitting static and dynamic forces. The other arm (5) of the corresponding double-arm lever (3) is hingedly connected to bracket-shaped leaf springs (22, 23) of corresponding means (21) for amortization of the dynamic forces.
Abstract:
Disclosed is a mobile robot adapted to traverse vertical obstacles. The robot comprises a frame and at least one wheel positioned in a front section of the robot, at least one middle wheel positioned in a middle section of the robot, at least one back wheel positioned in a back section of the robot, and at least one further wheel in the front, middle or back of the robot. The robot also comprises at least one motor-driven device for exerting a downward and/or upward force on the middle wheel and at least two motors for driving the wheels and the motor-driven device. Also disclosed is a method of climbing using a mobile robot as disclosed.
Abstract:
A tri-axle vehicle particularly well suited for (but not limited to) use in tree or cereal harvesting applications, such as forestry. The vehicle has a rigid chassis having a first, steering, axle at one end of the chassis and second and third, drive, axles, at the other end of the chassis. Suspension arms are pivotally mounted on the chassis and operably connected to respective axles. Respective lifting means interconnecting the suspension arms to the chassis are also provided to selectively raise or lower the axles relative to the chassis.
