Off-Road Truck Suspended with Rubber Spring Device

Номер: US20120119464A1
Автор: Minoru Tazawa, Tomoyuki Moriyama
Принадлежит: KOMATSU LTD

A rubber spring device is formed by alternately laminating a plurality of layers of hard plates whose linear dimension W in a direction parallel to the longitudinal direction of each equalizer bar is shorter in plan view than a linear dimension H in a direction parallel to an axle direction, and rubber layers. The rubber spring device is disposed between an end portion of each equalizer bar and a center axle in an articulated dump truck, and is allowed to function as a suspension. Thus, even when the rubber spring device is deformed into an accordion shape, peak positions of an internal stress within each rubber layer can be dispersed and reduced, thereby preventing generation of cracks within each rubber layer.

A vehicle height adjustment device includes an actuator, a detector, and a controller. The actuator is driven when supplied with a current and is configured to change a relative position of a body of a vehicle relative to an axle of a wheel of the vehicle. The detector is configured to detect the relative position. The controller is configured to control the current supplied to the actuator to make the relative position a target value so as to adjust a vehicle height of the body. When a detection value of the detector is smaller than the target value of the relative position, the controller is configured to alternately supply an increase current and a maintenance current to the actuator. The increase current increases the relative position to increase the vehicle height. The maintenance current maintains the relative position to maintain the vehicle height. 1.

A system and a method for securing an attachment to work vehicle with a chassis and a suspension are described. A mounting frame with a frame attachment point disposed on a support can be attached to a work vehicle. The suspension can be caused to lower the mounting frame relative to ground by lowering the chassis of the work vehicle. The work vehicle can be maneuvered to align the frame attachment point with a corresponding attachment point on the attachment. The suspension can then be caused to raise the mounting frame relative to ground by raising the chassis of the work vehicle. The frame attachment point can thereby engage the corresponding attachment point on the attachment, as the mounting frame is raised, in order to lift the attachment, with the attachment being thereby supported by the work vehicle solely via the mounting frame.
