受箱支持機構Ｃである。 33 is a bearing box 1 that supports the axle 7 described earlier.
This is a hydraulic cylinder that supports the right and left sides of the axle 7 by crimping the rod end on the end face of the lid 11 of the vehicle 0 via the load detector 34. As explained above, it is designed to operate in accordance with the setting operation of the yawing angle applied to the axle 7, so that the left and right support can be performed while always being aligned with the axis of the axle 7. Therefore, the hydraulic cylinder 33 is given an arcuate motion centered on the 0 point corresponding to the yawing angle, and a hydraulic cylinder 37 is installed to provide this motion. That is, a pin ring seat 38 is provided at the base end of the hydraulic cylinder 33.
The rod end of the hydraulic cylinder 37 is pivotally connected via the
Note that the base end of the hydraulic cylinder 37 is connected to a pedestal 39 with a hinge structure. Therefore, the hydraulic cylinder 3 responds to the yawing angle of the axle 7 given by the forward and backward movements of the actuating rod 21 described above.
7, the pedestal 36 of the hydraulic cylinder 33
The angle (posture) at the top is adjusted.

上に合致するように作動する。 The present invention has a structure as described in the embodiments above, and the test wheel 8 is placed on the track wheel 1,
The operating rod 21 is adjusted to connect the bearing housing 10 to the second bearing housing support mechanism B. Further, the hydraulic cylinder 12 is operated to cause the load receiving beam 15 to receive the reaction force, thereby causing the first bearing box support mechanism A to act. Furthermore, the hydraulic cylinder 33 is actuated to bring the load detector 34 into contact with the end face of the lid body 11, and as a result, the test wheel axle 7
This means that it is constrained in three directions: top and bottom, front and back, and left and right. If the electric motor 6 is started here, its rotation is transmitted to the test wheel 8 and its axle 7 via the track wheel 1. When it is desired to give horizontal movement to the axle 7, this purpose is achieved by alternately operating the hydraulic cylinders 33 by operating servo valves, switching valves, etc. of a hydraulic circuit (not shown).
In addition, when it is desired to give the axle 7 a yawing angle (yaw angle) α with respect to the rotational direction of the bearing ring 1, the actuating rod 2
The amount of protrusion of the actuating rod 21 can be changed by operating the rotation device 26 for adjusting the protrusion length.
The axial center of the axle 7 is aligned with the axial center of the axle 7 which is given an α angle.

機としてその効果は大である。 As described above, according to the present invention, it is possible to test the axle 7 while adjusting it in the front and rear, left and right directions, for example, when traveling straight, in a state in which it is displaced left and right, in a state in which vibration is applied to the left and right, and in a state in which it is subject to yawing. It is possible to accurately and easily measure the stress of the axle or the creep force between the rail and the wheel under various conditions such as a constant angle state, meandering state, lateral vibration and meandering state, etc. It is highly effective as a performance tester for wheel axles for railway vehicles.
