Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a linear motor propulsion platform that travels by the propulsive force of a linear monitor.

Generally, when mounting a main motor on a bogie, the scissor main motor and the bogie frame are constructed individually, and the main motor is mounted on the scissor dolly. When the main electric motor is of a rotary type, it is attached to the side beam of the bogie frame, and linearly moves the wheel axle through a flexible joint and a gear system that allow the wheels to move up and down and transmit power. If the main electric motor is a linear motor, it is attached to the side beam of the bogie frame, and the thrust is transmitted to the vehicle body via the side beam. By the way, in the case of a wrinkled linear motor, there is one in which the carriage and the near motor driver are integrated. An example of this will be explained with reference to FIGS. 1 and 2. In the figure, a bearing box 2 is fixed to both the front and rear ends of an onboard element l of a linear motor, and a bearing 4 is inserted and supported inside the skeleton bearing box 2 through a ring-shaped elastic body 3 made of rubber or the like. An axle 5 provided with wheels 6 is supported by the bearing 4 relative to the vehicle upper 11. A nine-air spring support 7 is provided on both sides of the center portion of the upper car body 1, and the car body 9 is supported by the above-mentioned car upper child 1 via a spring air spring 8 provided on the wrinkled air spring support 7. ing. The propulsion force of the onboard child 1 is transmitted to the steering body 9 through an arm 10 provided near the center of the onboard child 1, a center pin provided on the bottom of the vehicle body 9, and a thrust force connecting the arm 10 and the central bin U. This is done by lot 11.

However, in such a configuration, the portion that supports the axle 5 relative to the vehicle upper body 1 has a large rigidity in the longitudinal direction, and cannot allow the axle 5 to swing in the horizontal plane. Therefore, the lateral pressure acting on the wheels 6 when passing through one curve increases,
The drawbacks are that the contact area between the wheel flange and the rail causes a so-called self-squeezing noise and wear force on the wheel 6 and the rail. It should be noted that wear of the wheels 6 and rails has a significant impact on the gap size between the upper car 1 and the ground piece that constitute the linear motor, so in a bogie using a linear motor, it is necessary to minimize the wear. There was a problem that it had to be done.

In order to solve this problem, the front axle was attached to the swingable bogie frame via a bearing means placed in the center of the axle axle and allowed to swing, and the cough bogie frame and the upper bogie were attached to each other. Some have separate structures. and ζroga,
In this structure, due to the relationship with the shape of the onboard child (height and length in the longitudinal direction of the car body), if the onboard child is longer than the distance between the front and rear axles, and the wheel diameter is small, the axle and track surface The disadvantage was that the gap between the vehicle and the vehicle was small, making it impossible to mount a child on top of the vehicle.

In view of the above points, the present invention has been developed by integrally configuring the upper part of a linear train and the bogie frame, and by attaching an axle to the upper part so as to be able to swing. The purpose is to reduce lateral pressure acting on the axle, prevent wear on wheels and rails, and improve running stability.

The present invention comprises an upper car body and a bogie frame integrally formed, an axle is swingably attached to the car body through bearing means that allows the axle to swing, and the rolling of the car body is prevented. The present invention is characterized in that a suppressing means is provided to reduce the lateral pressure acting on the wheels during corner driving.

Next, one embodiment of the present invention will be described with reference to FIGS. 3 to 7. 3 is a plan view of a near motor propulsion truck according to the present invention, FIG. 4 is a top view of FIG. 3, FIG. 5 is a front view of FIG. 3, and FIG. Figure, 7th
The figure is a sectional view taken along the line CC in FIG. 3. In the figure, the same reference numerals as in the conventional example indicate the same members. Reference numeral 2' denotes a bearing box provided at the center of the front and rear of the vehicle upper body 1, in which a buffer body 14 composed of a spherical bearing B and a rubber force is connected to PJ, I! has been done.

The axle 5 is inserted into the front spherical bearing 13, and the axle 5 is inserted into the front spherical bearing 13.

A bearing 4' is provided at an intermediate portion between the spherical bearing 13 of the front axle 5 and the wheel 6, and the bearing 4' is built into the axle box 16. Further, the axle box 16 and the vehicle upper body 1 are connected via a shock absorber 17 such as a coil spring, and the axle box 16 and the shock absorber 11 are positioned symmetrically with respect to the bearing box 2' of the axle 5. It is set in. This axle box 16 and buffer body 1
By providing 7, the swinging of the vehicle upper part 1 is supported by the axle 5, thereby making it easier to suppress rolling. The rib is a disc brake holder provided on the shaft s16, and is a brake that supports the shoe 4 and the skeleton shoe 4, which are arranged corresponding to the wheel discs 15 provided on both end faces of the wheel 6, via the shoe holder n. Lever 19. At one end of the brake lever, there is attached a play mechanism consisting of a brake cylinder that presses the shoe base against the wheel disc.

A is a pillow supported on the air spring support 7 via nine air springs 8, and a is a support provided between the pillow and the vehicle body 9. It supports the load. Reference numeral 3 denotes a longitudinal force transmission rod that is installed between the vehicle upper 1 and the pillow bar and transmits the longitudinal force, Lotus is a receiver provided on the bottom surface of the vehicle body 1, and T is a rod that connects the receiver to the pillow bar. A shock absorber attached to a correspondingly provided image receiver Z transmits the left and right force between the receiver and the receiver via the shock absorber I. In addition, a predetermined gap is provided between the receiver and each shock absorber, and only when a force in the left and right direction that causes a large displacement is applied between the car upper L and the pillow support N, the ridges will move from side to side. It transmits power. A damper is provided between the car overboard l and the pillow base and serves as a buffer means to relieve the lateral force acting between them. (Source) is an adjustment plate installed between the bearing box 2' and the upper car body 1 in order to adjust the gap size between the upper car body L and the ground element. This is an adjustment screw that is sometimes used. J is the axle box 16 and buffer body 17

Since the brake mechanism and the brake mechanism are also provided in the axle box 16 as described above, the self-steering action of the axle 5 is not adversely affected. Due to the self-steering action of the axle 5 when traveling on a curve, the lateral pressure applied to the wheel 6 is equalized before and after the wheel is engaged. This makes it possible to reduce the maximum lateral pressure that conventionally acts on the wheels 6, and to reduce the squeaks that occur between the wheels 6 and the rails and the wear and tear of various parts. In addition, the vertical and horizontal rigidity of the shock absorber 17 provided between the car upper l and the axle box 16 prevents the bogie from moving in a meandering manner.
