  • Patent number: 10358177
    Abstract: An endless track assembly that mounts to a vehicle drive linkage and is operative to vary the track geometry or profile and terrain contact surface to differing terrains. The track assembly includes controlled idler wheel rocker arm suspensions for pivoting associated idler wheels at an assembly framework. In one assembly, a wheel and tire are supported to a track drive sprocket. The shape of the track assembly can be transformed to alternately engage and disengage the track or wheel with the terrain. In other constructions, the geometry of the track can be varied between triangular and circular shapes. The assemblies include pivotally controlled idler wheel suspensions that cooperate with a drive sprocket supported bladder, offset pie-shaped telescoping plates, and a collapsible membrane or tire to transform the track profile.

  • Patent number: 10309527
    Abstract: A continuously variable transmission (CVT), a transmission control system, and a method is provided. The control system is configured to determine a measured wheel speed of two driven wheels and a first driving wheel, calculate a first driving wheel expected speed based on the driven wheel measured speeds, a track width, and a wheel base, and calculate an actual wheel speed difference between the first driving wheel measured speed and the additional wheel measured speed. The additional wheel can be either of the driven wheels or a second driving wheel. The control system is also configured to calculate a theoretical wheel speed difference between the first driving wheel expected speed and the additional wheel measured speed, calculate a zeroed-out wheel slip based on the difference between the actual wheel speed difference and the theoretical wheel speed difference, and determine whether the zeroed-out wheel slip exceeds a predetermined threshold.

  • Patent number: 9586635
    Abstract: A track system for steerable vehicles having at least one axle. The track system is capable of adjusting to changes in terrain by pivoting in clockwise and counterclockwise directions relative to an axle assembly as the vehicle moves across the ground. The pivotal movement of the track system relative to the axle assembly is restricted by a limiter attached to an inboard member of the track system frame. Pivotal movement is limited by the axle assembly housing engaging the limiter when the track system pivots in either a clockwise or counterclockwise direction to a maximum point along a pivot arc.

  • Patent number: 8248005
    Abstract: A braking circuit is adapted to supply generatively produced energy of the motor as load resistance to a bipolar transistor. The braking circuit has a voltage regulator, which controls a voltage, applied to the base terminal of the bipolar transistor to achieve an associated controlled voltage based on a reference voltage. A first power supply connector of the electrical motor, in the generator mode of operation of the electrical motor, is coupled to a collector terminal of the bipolar transistor and to the voltage input of a voltage regulator. A second power supply connector of the electrical motor is coupled to an emitter terminal of the bipolar transistor and is coupled to a reference input of the voltage regulator via a resistive branch including at least one electrical resistor.

  • Publication number: 20120090903
    Abstract: This invention generally relates to track systems and traction assemblies for use as wheel replacement for normally wheeled vehicles. The track system uses a traction band disposed about a sprocket wheel, idler wheels and road wheels for propulsion. The idler wheels and road wheels are typically pivotally mounted to a support frame, itself configured to be coupled to the sprocket wheel via a support member. The track system also comprises a movement limiting link mounted both to the support member and to the vehicle frame. The movement limiting link limits longitudinal and lateral movements of the track system, such as to prevent contact between the track system and the vehicle.

  • Patent number: 8056655
    Abstract: A drive system has a drive-system frame operatively connectable to a vehicle. The drive-system frame is capable of pivotal movement relative to the longitudinal axis of the vehicle to steer the vehicle. The drive-system frame is incapable of pivotal movement with respect to the frame of the vehicle in a plane parallel to the longitudinal axis and normal to the ground when the vehicle is on flat level terrain and steered straight. A rail is pivotally mounted to the drive-system frame. A ground-engaging endless belt is in sliding engagement with the rail. The belt is operatively connectable to an engine to propel the vehicle. The drive system is operatively connectable to the steering device of the vehicle. A steering angle stopper is disposed on the vehicle such that a steering linkage of the vehicle does not bear a force created when the stopper is engaged. A vehicle is also described.

  • Patent number: 7870914
    Abstract: This invention relates to a traction assembly for a vehicle which uses an endless traction band and a plurality of wheels for propulsion. More particularly, the traction assembly comprises a sprocket wheel which has a different size and number of sprocket teeth depending on whether the traction kit replaces the front wheels or the rear wheels of the vehicle. The sprocket wheel of the traction kit can also be configured such that its sprocket teeth are laterally offset. The traction kit can also comprise an anti-torque system that prevent physical contact between the traction kit and the vehicle and that can bias the position of the traction kit in order to improve the steering performance. Finally, the traction assembly can comprise a pivotable extension which lengthens the traction assembly and improves its traction capabilities.
