摘要： PURPOSE:To shorten the time of control, by providing a driving section, a rotary member instruction unit and a control section for each axle unit of a multi-axle vehicle and determining a steering angle corresponding to the movement posture of the vehicle selected through a control panel, to control the driving section. CONSTITUTION:After a movement posture is determined through a control panel 3' holding numerous movement postures in a microcomputer, a steering wheel 1 is operated for steering a vehicle as it is moving. At that time, the output of an angle detector 19, which finds out the steerint angle of the wheel 1, is sent to a control unit 2 which collates the detected value of the steering angle with the movement posture so that a steering angle corresponding to the movement posture is determined for each axle unit 5. A steering instruction is then applied to the motor 6 of each axle unit 5 through an amplifier 4 to turn a rotor 12 by the motor to control an oil pressure changeover valve 14' through a lever 13 and a linkage 15. As a result, a turntable 9 is rotated by a hydraulic cylinder 16 to execute the steering.

摘要： PURPOSE:To simplify the construction of bending device by installing cam shaft having cams which keep guide plates disposed bendably on both side walls of track girder in plural guide conditions and a connecting means which rotates the cam shafts and transmits the displacement of cam to the guide plate. CONSTITUTION:Guide plates 3 which extend longitudinally and can be bent and cam shafts 5a, 5b having a plurality of cams which keep the guide plates 3 in plural guide conditions in the width direction of the track girder 1 are installed on both sides of a switch track girder 1. The cam shaft 5a, 5b are driven by a power cylinder 14 via an arm 12, so that the guide plate 3 forms a convex or concave curved surface toward the center of track girder in the width direction, which enables the switch girder 1 to switch into track girder 2b or 2c. This construction simplifies the bending mechanism of guide plate 3, and provides simplification by reducing the number of parts without using a complex link mechanism.
