Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a linear motor propulsion truck for a vehicle.

Conventionally, a vehicle bogie has an axle rotatably attached to the front and rear of a frame called a bogie frame via bearings, and the vehicle body is mounted on the bogie frame via a supporting device that can rotate, move laterally, and move up and down. is supported. The bogie frame is
It is composed of two side beams on the left and right and a horizontal beam that connects these to each other, and has the strength necessary to transfer the load of the vehicle body to the wheels. When the main electric motor is a normal motor, it is attached to the side beam of the bogie frame and connected to a gear box provided on the axle via a flexible joint to enable vertical movement of the wheels. Also,
If the main electric motor is a linear motor, a configuration can be considered in which this is attached to the side beam of the bogie frame and the propulsive force of the motor is transmitted to the vehicle body via the side beam. As described above, in conventional carts, the electric motor and the cart frame are constructed separately and then combined to form the cart, which has the disadvantage of poor workability and a complicated structure.

SUMMARY OF THE INVENTION An object of the present invention is to provide a linear propulsion truck that can simplify the configuration, improve workability, and improve followability for track irregularities.

The present invention includes: an axle having wheels at both ends and arranged in parallel; side beams rotatably connected at each end to the respective axles and arranged in parallel on both sides in the direction of the bogie;
The present invention is characterized in that it is comprised of a linear motor upper body attached to each side beam at a plurality of points in the front-rear direction of the bogie via elastic bodies.

Next, the present invention will be explained with reference to the drawings. FIG. 1 is a plan view showing an embodiment of a cart according to the present invention, FIG. 2 is a sectional view taken along line AA in FIG. 1, and FIG. 3 is a sectional view taken along line B in FIG. 1.
B sectional view, FIGS. 4 and 5 are sectional views of the same parts as FIG. 3 showing the state of the truck during running, and FIG. 6 is a CC sectional view of FIG. 1. In the figure, reference numeral 1 denotes a linear motor upper body with arms 2 provided at the front and rear sides of both sides. It is attached to the burr 7. 8 is a wheel, and 9 is an axle. The wheels 8 are provided at both ends of the axle 9, and the axle 9 is attached to both ends of the side beam 7 via bearings 10 and elastic bodies 11, respectively. Reference numeral 12 designates a cap for mounting and covering a bearing 10 and an elastic body 11 when the axle 9 is mounted on both ends of the side beam 7. 13 is an air spring, and 14 is a vehicle body. Reference numeral 15 is a thrust generating plate which is a part of the linear motor vehicle upper element 1 (the secondary conductor is the primary field element when the primary field element is installed on the ground, and the primary field element is the secondary conductor when the secondary conductor is installed on the ground). ). 16 is a cooling air passage provided integrally with the thrust generating plate 15, and in order to cool the thrust generating plate 15, cooling air flows from the air supply port 17 to the exhaust port 18 as shown by the arrow in FIG. Linear motor vehicle upper element 1 configured in this way
An arm 19 is provided on the upper surface of the arm 19.
The rod 22 is attached to the arm 23 provided on the vehicle body 14.
and each connection has a pin 20.
and an elastic body 21 are provided. With this configuration, the vehicle body 14 and the linear motor upper part 1 are configured to mutually allow vertical, horizontal, and horizontal turning displacements. 24 is a linear motor ground element, which is provided on the orbit. A stopper 25 is provided on the upper surface of the linear motor upper body 1 in correspondence with the arm 23. The stopper 25 is provided in a position opposite to the arm 23 to suppress the movement of the vehicle body 14 in the left and right direction within a predetermined range. An elastic body 26 is provided.

In such a configuration, when a vehicle equipped with the bogie runs, the linear motor ground element 24 is located at the center of the bogie and when it is located at the edge of the bogie as shown in FIGS. 4 and 5. The linear motor upper body 1 deforms in different ways. That is, the fourth
In the case shown in the figure, the linear motor upper part 1 is supported by the arm 2, and since the suction force P acts on the central part, a downward convex deformation occurs. Also, the fifth
In the case shown in the figure, since the suction force Q acts on both outer sides of the arm 2, an upwardly convex deformation occurs, contrary to the above. Due to these deformations, the gap between the linear motor upper element 1 and the linear motor ground element 24 changes, and the thrust fluctuates. In addition, since vibration and noise are also generated, in order to minimize these, the thrust generation plate 1
5 and the cooling air passage 16 are integrated, and the cooling air passage 1
6 is used as a strength member. This structure is also effective in obtaining strength because the linear motor upper body 1 also serves as a horizontal beam for the bogie frame. By the way, the car body 14 has an air spring 1
The car body 14 is supported by the truck via the air springs 13, and the impact is alleviated by moving the car body 14 left and right due to the deformation of the air springs 13. However, since it is dangerous if the left and right movement becomes large without any limit, this is not supported by the stopper. 25. Incidentally, relative displacements of the bogie and the vehicle body 14 such as vertical, horizontal, and horizontal turning while traveling are permitted by connecting the arms 19 and 23 with the pin 20, the elastic body 21, and the rod 22. Furthermore, the displacement between the side beams 7, axle 9, linear motor upper body 1, and other members due to the above-mentioned deformation is allowed by the elastic bodies 3, 4 of the arm 2 part and the elastic body 11 of the bearing 10 part. are doing.

According to such a configuration, since the linear motor vehicle upper element 1 is used as a component of the bogie frame, the configuration is simplified and the workability is improved. Also,
The side beams 7, axle 9, and linear motor upper body 1 are all elastically connected, and the individual up and down movement of each wheel 8 due to track irregularities during running and the twisting of the bogie frame in response to this movement can be easily performed. , it is possible to prevent dangers such as derailment due to changes in wheel load. Furthermore, by connecting the car body 14 and the bogie with the pin 20, the elastic body 21, and the rod 22, relative displacement between the car body 14 and the bogie can be tolerated with a simple configuration, and traction force and braking force can be increased. can be easily communicated. Furthermore, since the linear motor upper element 1 is integrally provided with the cooling air passage 16 on the upper surface, it has sufficient rigidity, and the change in air gap with the linear motor upper element 24 is reduced, resulting in changes in thrust force. It is possible to prevent the occurrence of noise, vibration, and noise.

As explained above, according to the present invention, the structure of the entire truck can be simplified, and the workability of various operations on the truck can be improved. Further, by improving the ability to follow track irregularities, dangers such as derailment can be prevented.
