  • Patent number: 6575050
    Abstract: A control device for a backhoe that moves four separate reversible hydraulic valves in any combination or all at the same time with only one human hand needed to manipulate said controls. These valves are controlled through an organized series of arms, levers, and push rods. Lever one 1 can pivot forward or backward, move up or down, push forward or pull backward, and move to the left or right. Lever two 2 pivots up or down at lever four 4, therefore lever one 1 moves with lever two 2 as a unit. Lever four 4 spins around lever three 3 with lever two 2 and lever one 1 as a unit. Lever three 3 pivots forward and backward taking lever four 4, lever two 2, and lever one 1 with it as a unit. Lever one 1 pivots forward or backward to actuate valve 20 through a number of pins, rods, and arms. As lever one 1 is moved up or down, it pivots lever two 2 causing valve 22 to be actuated, leaving valve 20 uninterrupted.

  • Patent number: 6461270
    Abstract: A pair of power rollers which is gripped between an input disk and an output disk and transmits torque by friction, is supported rotatably by a pair of trunnions. The upper ends and lower ends of the trunnions are respectively connected by links, and the power roller is prevented from being driven out from between the input disk and output disk by the grip force. When the trunnions and the power rollers are displaced by the servopistons in the trunnion axis direction in mutually opposite directions, the trunnions and power rollers gyrate around the trunnion axis as pivot, and a speed change will occur. Links are provided with slots which lengthen in the trunnion axis direction, and are supported in the transmission case free to displace in the trunnion axis direction via pins inserted in the slots.

  • Patent number: 6443024
    Abstract: The present invention relates to an operating device with a control lever (1) and an operating console (2), and provided with two pivot axes about which the lever can be alternately pivoted relative to the operating console, for adjustment between a number of operating positions. The operating positions of the control lever about said pivot axes are intended for transmission into a corresponding operating condition of a device to be operated. Said pivot axes are created by four support members (3, 4, 5, 6) for the control lever (1) in the operating console, in pairs defining each one of the pivot axes for the control lever. The support members are biased towards their respective paths (7, 8, 9, 10) defined in the operating device, in which paths the support members, alternately and in pairs, are blocked and operable, respectively, to allow control movement of the lever.

  • Patent number: 6440034
    Abstract: In the toroidal-type continuously variable transmission, the radial clearance of a second radial needle roller bearing 30 for supporting the power roller 8 on the periphery of the pivot shaft portion 26 of the displacement shaft 7 is set larger than the radial clearance of a first radial needle roller bearing 27 for supporting a support shaft portion 25 on a trunnion 6. By increasing the radial clearance of the second radial needle roller bearing 30 in this manner, an increase in the surface pressures in the contact portions between the rolling surfaces of needle rollers 32, 32 and the inner peripheral surface of the power roller 8 and the outer peripheral surface of the pivot shaft portion 26 can be restricted, thereby enhancing the durability of the toroidal-type continuously variable transmission. Also, by reducing the radial clearance of the first radial needle roller bearing 27, the inclination of the displacement shaft 7 is minimized, thereby stabilizing the rotation speed change operation thereof.

  • Patent number: 6440035
    Abstract: To provide a continuously variable transmission for motor vehicles which transmits power with a speed change from a driving member to a driven member. In the continuously variable transmission, power transmission is effected by moving a carrier which supports a shifting rotating member in frictional contact with the driving member and the driven member. No other special mechanism other than the continuously variable transmission is needed to push to move the motor vehicle with a small force. At least either one of the driving member and the driven member is driven by a power disconnecting means to move away from the other member along the axis of a transmission shaft, thereby releasing at least one of the driving member and the driven member from frictional contact with the first and second friction transfer surfaces.

  • Patent number: 6439071
    Abstract: The transmission mechanism comprises a lever (12) which can rotate around an eccentric shaft (11) of a rotating disk-crank (10). The lever (12) is guided in its movement by cam means (15a) and acts upon an arm (19) which is attached for joint rotation to an output shaft (3). Advantageously the disk-crank (10) is driven through a connecting rod (8) from another disk-crank (1) which can rotate around a shaft which is different from that of the first disk-crank (10). It doesn't require adjustment or setting up and it has a low cost. The transport device has on the output shaft the wheels for drawing chains with transporting bars provided with clamps for the sheets.

  • Patent number: 6435048
    Abstract: A compact telescopic leg assembly includes a generally cylindrical drive motor mounted axially within the inner leg and coupled to a drive collar by a pedestal mount. A drive screw is threadably coupled to a first drive collar which is attached to the inner leg to raise and lower as the drive screw is rotated by the motor. The pedestal mount couples the motor through the first drive collar to a second drive collar which is coupled to an intermediate leg telescopically receiving the inner leg. Gears couple the motor-driven drive screw to a rotatable power nut coupled to the second drive collar. A fixed drive screw extends from the base within an outer leg upwardly through the second drive collar and cooperates with the power nut within the second drive collar to simultaneously extend and retract the legs as the motor rotates the motor-driven drive screw.
