あるという欠点があつた。 Conventionally, when mounting a motor on a truck, it has been customary to mount a motor that is configured separately from the truck. When the main electric motor is of a rotary type, it is attached to the side beam of the bogie frame, and the wheel axle is driven via a gear system from a flexible joint to allow vertical movement of the wheels. If the main electric motor is a linear motor, it is attached to the side beam of the bogie frame, and the thrust of the motor is transmitted to the vehicle body via the side beam. A conventional example using a linear motor as described above is shown in FIGS. 1 and 2. In the figure, linear motor 1 corresponding to the onboard child
Bearing boxes 2 are fixed to the front, rear, left, and right sides of the vehicle, and bearings 4, axles 5, and wheels 6 are attached via ring-shaped elastic bodies 3 made of rubber or the like. Further, air spring supports 7 are fixed to both sides of the central portion of the linear motor 1 to support a vehicle body 9 via air springs 8. Further, an arm 10 is attached near the center of the linear motor 1, and is configured to transmit thrust to the vehicle body 9 via a thrust rod 11 and a center pin 12 installed on the vehicle body 9. In such a configuration, the rigidity of the axle support part in the longitudinal direction is large, so the wheel flange wears out due to increased lateral pressure when passing through a curve, and so-called "squeak" noise occurs due to contact between the wheel flange and the rail. There were some shortcomings. Furthermore, the ground secondary conductor (reaction plate) that hits the linear motor 1 and ground element due to wear of wheels and rails.
There was a drawback that it was difficult to maintain the gap size between the two at a predetermined value.

The thrust rod 11 and the center pin 12 constitute a longitudinal force transmitting means. Reference numeral 14 is provided between the bearing box 2 and the lower part of the vehicle 1, and is used to adjust the gap between the lower part of the vehicle 1 and the lower part (not shown) when the diameter of the wheel 6 changes due to tread milling, etc., for example. This is a sim for It is not necessary to provide the shim 14 if the wheel 6 or the entire wheel axle is replaced and the distance between the wheel 6 and the track of the vehicle upper 1 does not change. Reference numeral 15 denotes bearings disposed at both the intermediate portions between the spherical surface 13 of one axle 5 and the wheel 6, and a bearing box 16 is provided around the outer periphery of the bearing 15. A torsion bar bearing 17 is attached to the upper surface of the vehicle upper part 1 and supports a torsion bar 18. Reference numeral 19 denotes a torsion bar arm 19 attached to the torsion bar 18, and the end of the arm 19 and the bearing box 1
6 are connected by a link 20. The torsion bar bearing 17, torsion bar 18, and torsion bar arm 19 constitute a rolling support mechanism. Reference numeral 21 denotes a shim for adjusting the installation height of the torsion bar bearing 17. Similar to the shim 14, the shim 21 is not necessary if the distance between the onboard child 1 and the track does not change. Reference numeral 25 indicates an arm provided on the upper surface of the vehicle upper part 1 corresponding to the horizontal beam 27, 28 indicates an arm provided on the lower surface of the horizontal member 27, and 26 connects the arms 25 and 28.

記間隙を調整することも可能である。 In such a configuration, when traveling on a curved track, the upper car body 1 is supported by the axle 5 via the spherical bearing 13, and the axle 5 is swingably attached to the bogie frame. Therefore, the axle 5 is tilted in the longitudinal direction of the vehicle body 9 due to the self-steering effect of the wheels 6 due to the road surface inclination. Therefore,
The lateral pressure applied to the wheels 6 is equalized between the front and rear wheels 6, and the lateral pressure applied to the front wheels 6 can be reduced. This can reduce wear on the wheels 6 and rails, as well as reduce squealing noise. It can also travel at high speed on curved tracks with a small radius. Furthermore, since the onboard lower element 1 is supported by the axle 5 and the wheels 6 via the spherical bearing 13, the distance between the upper onboard element 1 and the ground element does not change, and the gap between the upper onboard element 1 and the ground element is kept constant. can be kept. Note that it is also possible to adjust the gap using the shims 14 and 21.

In addition, although the structure using the torsion bar 18 was demonstrated in the said one Example, it is not limited to this. That is, a mechanism for keeping the vehicle upper body 1 parallel to the axle 5, for example,
Any structure may be used as long as a slider plate is provided between the upper part of the vehicle and the upper part of the vehicle 1, allowing displacement in the horizontal direction and supporting displacement in the vertical direction.
