Description

[Detailed description of the invention] The present invention relates to linear motor propulsion rate.

Conventionally, when mounting a motor on a truck, it is customary to mount a motor that is configured separately from the truck on the truck.

If the main electric motor is a rotary type, it is mounted on the side of the bogie frame to allow vertical movement of the wheels. If the main electric motor is a linear motor, this is attached to the bogie frame structure, and the thrust of the motor is transmitted to the vehicle body via the lateral side. A conventional example using a linear motor as described above is shown in FIGS. 1 and 2.

In the figure, bearing boxes 2 are fixed to the front, rear, left and right sides of a linear motor l, which corresponds to the onboard element, and bearings 4. Axle5. Wheel 6 is installed. Furthermore, air spring supports 7 are fixed to both sides of the central portion of the linear motor 1,
A vehicle body 9 is supported via an air spring 8. Further, an arm 10 is attached near the center of the linear motor 1, and has a structure in which thrust is transmitted to the vehicle body 9 via a thrust rod U and a center pin installed on the vehicle body 9.

In such a configuration, the rigidity of the axle support part in the longitudinal direction is large, so that the so-called "squeak" occurs due to wear of the flange part of the wheel 7 and contact between the wheel flange and the rail due to increased lateral pressure when passing through a curve. There were drawbacks such as. Furthermore, there is a drawback that it is difficult to maintain a gap size between the linear motor l and the ground secondary conductor (reactor plate) corresponding to the ground element at a predetermined value due to wear of the wheels and rails.

In view of the above points, the present invention supports the onboard element of a linear motor by an axle so as to maintain a constant gap with the ground element, and also supports the axle so as to be able to swing. Improve performance by reducing wheel lateral pressure, preventing wear on wheels and rails, improving running stability, maintaining gap dimensions between linear motor car upper and ground axle, and reducing noise such as squeaks. The purpose is □.

The present invention is configured such that the axle shaft of the axle box support device that supports the axle box provided at the end of the axle is swingable, and that the upper part of the linear motor is provided with spherical bearings at the center of the front and rear axles. By providing means for suppressing the rolling of the upper part of the vehicle, the passing performance on curved tracks is improved and the lateral pressure of the wheels is reduced.

Next, one embodiment of the present invention will be explained with reference to FIGS. 3 to 6. In the figure, a bearing box 2 is provided at a position corresponding to the center of an axle 5 on the upper surface of a vehicle upper part of a linear near motor. The bearing box 2 has a built-in spherical bearing, and the upper wheel 1 is supported on the axle 5 via the spherical bearing 13'' and the bearing box 2. A shaft SZa is provided on the outside of the wheel, that is, at the end of the axle 5.The shaft SZa supports the frame of the bogie frame via the shaft spring. The platform frame supports] n are connected by horizontal beams n to form the platform frame. 7 is a spring plate for receiving an air spring 8; 11 is a spring holder; The car body 9 is supported on the bogie frame. Reference numeral 11 is a thrust rod whose one end is attached to the horizontal beam i, and the other end is connected to the center bin ν attached to the bottom of the car body 9. 14 is provided between the bearing box 2 and the lower car body 1 to adjust the gap between the lower car body l and the ground element (not shown). This is a sim for

The positive bearings are located at both the intermediate portions of the spherical Hashimoto 1 of one axle 5 and the wheel 6, and a bearing @16 is provided on the outer periphery of the armpit bearing. Reference numeral 17 denotes a toss neck member bearing attached to the upper surface of the vehicle upper l, which supports the torsion bar inlet. The ratio is a torsion bar arm 19 installed for the toshiromper, and the end of the skeleton arm (2) and the bearing box 16 are connected by a link. The shim is a shim for adjusting the installation height of the torsion bar bearing 17. Reference numeral 2 indicates an arm provided on the upper surface of the upper carriage 1 corresponding to the horizontal beam I; This is a rod that transmits the longitudinal force of l to the bogie frame. It should be noted that a plurality of scissor arms δ, 28 and p-rad handles are provided at symmetrical positions with respect to the center of the cart. 29 is an arm provided on the upper surface of the upper part of the car corresponding to the 3122, and 29 is an arm provided on the side of the 4th bar.
Reference numeral (9) is a rod that connects the arm 4 and the arm 4 and transmits the left and right forces between the upper car body 1 and the bogie frame.

In addition, armpit arm 4.

A plurality of targets and caps are also provided at symmetrical positions with respect to the center of the truck. In addition, the movement of the vehicle body 9 in the left and right direction and the left and right force are controlled by a stopper metal A attached to the lower surface of the vehicle body 9.
32 and cough stopper fittings! The transmission is transmitted through a stopper rubber (corresponding to this) provided on the frame.

When traveling on a curved track with such a configuration, the upper car body 1 is supported by the axle 5 through the spherical bearing port.
In addition, since the cough axle 5 is swingably attached to the truck frame, the axle 5 is tilted in the longitudinal direction of the vehicle body 9 due to the self-steering effect due to the screen tilt of the wheels 6. Therefore, the lateral pressure applied to the wheels 6 is equalized in the front and rear wheels 6, and the lateral pressure applied to the front wheels 6 can be reduced. This not only reduces wear on the wheels 6 and rails, but also! ! It can also reduce squealing noise and can run at high speed on curved tracks with a small radius.

By the way, the rolling distance of the child on the train is 1m.
17. ) - Shin ■ t < -1g, Toshin Cowper Arm 19. It is supported by a rolling support mechanism constituted by a bearing and a bearing box 16. In addition, in the above-mentioned embodiment, a structure using a Toshi impermeable jacket was described, but the present invention is not limited to this. In other words, a mechanism for keeping the upper body l parallel to the axle 5, for example,
Any structure may be used as long as a plate is provided between the axle 5 and the vehicle upper part 1 to allow displacement in the horizontal direction and support displacement in the vertical direction.

As explained above, according to the present invention, curve running performance can be improved and lateral pressure applied to the wheels can be reduced, so wear of the wheels and rails can be reduced, and compared to the conventional one, it is possible to It is capable of holding the Oji Seki gap for a long time. Further, noise such as squeaks caused by contact between wheels and rails can be reduced.
