摘要： PROBLEM TO BE SOLVED: To reduce reaction force of a trailing arm acting on a support part to a bogie frame and suppress the occurrence of vibration due to rickety motion. SOLUTION: This is a support leg device in a linear vehicle which can raise and lower a wheel 3 supported in an overhang manner at one end of a trailing arm 11 whose the other end is supported on a bogie frame 1 due to coming in and out of a rod of a cylinder 13 whose one end is supported on the bogie frame 1. A width B of a support part 11b for the bogie frame 1 at one end of the trailing arm 11 is increased to eliminate eccentricity of the support part 11b and the wheel 3 for a center C in the direction of width. Consequently, since reaction force acting on the support part for the bogie frame of the trailing arm is reduced, the inclination of the trailing arm is reduced, and unstable vibration for a vehicle does not occur, even if a rickety motion occurs in a bearing in the support part.

摘要： PURPOSE:To enable it to support a wheel at the specified position through a simple structure by interposing an expansion cylinder and a cushion unit between a trailing arm supporting the wheel free of rocking motion and a car body, and installing a mechanism locking an axial displacement and its releasing mechanism both in this expansion cylinder. CONSTITUTION:A wheel 40 is supported on a car body 50 free of rocking motion via a trailing arm 43, and an expansion cylinder and a compressed gas-filled cushion unit 16 both are interposed between the trailing arm 43 and the car body 50 in series. In addition, two segments 13 and 14 are installed in an inner part of this expansion cylinder as a mechanism locking the axial displacement of a piston 2 at both the expansion and contraction positions, through which the wheel 40 is locked to a lifting position and a traveling road surface (51) position. At the time of being locked, two subpistons 2B and 2A are displaced to some extent and operates as a lock releasing mechanism only when hydraulic pressure is supplied in an extension direction at the contraction position and in a contraction direction at the extension position.

摘要： PURPOSE:To realize the deceleration control from the specified speed by controlling the torque within the preset range, realizing the control at the prescribed deceleration, and releasing the hydraulic pressure of the brake cylinder to realize the anti-skid control when the actual torque obtained by the conversion is remarkably smaller than the simulated torque. CONSTITUTION:The detected signal from a load cell 3 when the brake is applied is received by a controller 5, and the simulated torque predicted from the preset torque is obtained. This simulated torque is compared with the actual torque converted from the detected signal of the load cell, the hydraulic pressure of the brake cylinder is controlled so that the actual torque obtained by the conversion may be the value of the simulated torque or under, and the control is realized with the constant torque and the deceleration. When the actual torque obtained by the conversion is remarkably smaller than the simulated torque, the hydraulic pressure of the brake cylinder is released to realize the anti-skid control and to stop the vehicle. The braking torque 7 is kept constant near 500kg.m where the braking starting speed is set to 500km/h or up to 70 km/h.
