  • Patent number: 10495118
    Abstract: Provided is a hydraulic drive device, wherein the hydraulic drive device is provided with: a cylinder (101); a rod (103); a piston (102); a hydraulic pump (107); a tank (113); a valve (106) that can be switched between a positive state of connecting the hydraulic pump (107) and a head chamber (101h) and connecting a rod chamber (101r) and the tank (113), and a negative state of connecting the hydraulic pump (107) and the rod chamber (101r) and connecting the head chamber (101h) and the tank (113); and a confluence channel (114) at which, when the valve (106) is in the positive state, at least a portion of hydraulic oil going from the rod chamber (101r) to the tank (113) is merged into hydraulic oil going from the hydraulic pump (107) to the head chamber (101h).

  • Patent number: 10281361
    Abstract: A tire uniformity tester having: a spindle capable of rotating while holding a tire; a drum; a pressing mechanism that rotatably supports the drum and makes it possible to press a tire attached to the spindle into the drum through the relative movement of the drum and spindle; a uniformity measurement unit for measuring the uniformity of the tire during forward rotation and reverse rotation; and a control device. The control device controls the driving of the rotation of the spindle and the relative positions of the spindle and drum so that when the rotation direction of the spindle is reversed, the spindle and drum are separated from each other such that the spindle rotation speed reaches zero in a state in which the outer peripheral surface of the drum and the tire tread surface are not in contact with each other.
