摘要： A motorized vehicle has a vehicle body, at least a pair of wheels mounted on the vehicle body for undergoing rotation to cause the motorized vehicle to undergo travelling, and a pair of electric motors each mounted on the vehicle body to selectively undergo forward and reverse rotation to rotationally drive a respective one of the wheels. A first switch is connected to the electric motors so that operation of the first switch causes the electric motors to undergo rotation simultaneously in opposite directions to turn the motorized vehicle in a first direction while the motorized vehicle does not undergo travelling. A second switch is connected to the electric motors so that operation of the second switch causes the electric motors to undergo rotation simultaneously in opposite directions to turn the motorized vehicle in a second direction opposite to the first direction while the motorized vehicle does not undergo travelling.

摘要： A transmission has an HMT which is in parallel with an HST both driving two planetaries which are used for forward/reverse and for differential steer. A two or three mode HMT is created by having a first HST in parallel with two or three mechanical power paths defined by separate clutches. One clutch has a speed reversing gear to produce reverse output speed. A four-element planetary sums the parallel flow and delivers variable speed and torque to two output shafts. The differential steer is created by two planetaries connected with the outputs of the HMT and a second HST. The planetaries have a speed reversing gear on one power path connection. The second HST controls the differential speed between the output shafts by adding speed to one and subtracting speed from the other.

摘要： A self-propelled working vehicle comprises a front wheel unit, a rear wheel unit including a left rear wheel and a right rear wheel, and a drive transmission apparatus for transmitting drive from an engine to the rear wheel unit. The drive transmission apparatus includes a first drive transmission mechanism for transmitting the drive to the left rear wheel and a second drive transmission mechanism for transmitting the drive to the right rear wheel. The first transmission mechanism is arranged at the left side of the vehicle body, while the second transmission mechanism is arranged at the right side of the vehicle body. A brake assembly is arranged between the first drive transmission mechanism and the second drive transmission mechanism for acting on an output shaft of a first transmission unit and an output shaft of a second transmission unit. The first and second transmission units act as first and second change speed devices, respectively, which are operable independently of each other.

摘要： An object is to provide a steering system for a tracklaying vehicle which is capable of preventing overrun of a motor during a pivot turn irrespective of the load of the road surface and does not cause a shortage of power during a turn. The steering system is comprised of a pair of brakes for right and left output shafts and designed to transmit the driving force of a hydraulic motor to the output shafts through a planetary gear mechanism. A transmission of a driving force from the hydraulic motor to the planetary gear mechanism is interrupted after concurrently carrying out actuation of a brake for either one of the right and left output shafts and a transmission of a driving force from the hydraulic motor to the planetary gear mechanism for a specified period of time, when the vehicle carries out a pivot turn. During a pivot turn of the vehicle, the engine is controlled such that a vehicle body speed obtained by a bevel shaft rotational speed detector becomes equal to a specified value.

摘要： A motorized scooter is disclosed that comprises a steering shaft mounted for rotation about its axis. A tiller is connected to said steering shaft to rotate said steering shaft, and pivotable relative to said steering shaft. A pivot block is mounted on the free end of said steering shaft, a pair of forks on said tiller straddle the pivot block, and a pivot pin passes through the forks and the pivot block. The pivot block has a pair of lubricating plates of low-friction material on either side of it, so that the forks rest on said lubricating plates, to facilitate pivoting of said steering column. A strut of variable length is connected to the tiller and to said steering shaft so that pivoting of the tiller requires a change in the length of said strut. The strut comprises an inner shaft and an outer sleeve movable along said shaft to vary the length of said strut. Two helical coil springs that in a relaxed condition have an inside diameter smaller than the shaft grip the shaft frictionally to resist movement along the shaft. The coil springs are wound in opposite senses, and are positioned end to end, with their outer ends engaging the sleeve to prevent movement of the sleeve along the shaft and their abutting inner ends projecting radially. An actuating sleeve encircles the coil springs, free to rotate, and has one circumferential end engaging the projecting ends of the coil springs. A Bowden cable has its sleeve and its core respectively attached to the outer sleeve of the strut and to the actuating sleeve. Attached to the other end of the Bowden cable is a lever arranged to apply a tension to the core of the Bowden cable, and thereby to apply to the actuating sleeve and thence to the inner ends of said coil springs a force in a direction tending to increase the diameter of said coil springs.

摘要： Disclosed is a driving apparatus for a robot cleaner enabling drive wheels to be in contact with a floor all the time. The driving apparatus for a robot cleaner includes a robot cleaner main body, driving motors mounted in the robot cleaner main body, and for transferring power to drive wheels, driving motor housings hinged with the robot cleaner main body, and for accommodating the driving motors therein, and pressure members disposed between the robot cleaner main body and the driving motor housings, and for pressing the driving motor housings. Accordingly, the driving motor housings are mounted to rotate about the center of the rotation hinges so that the drive wheels come in contact with the floor all the time, preventing the drive wheels from being lifted over the floor and making lost rotations due to curved portions of the floor or obstacles.
