Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a bogie for a railway vehicle using a linear motor, and more particularly to a bogie for a railway vehicle in which a linear motor is mounted on a bogie frame.

[0002]

2. Description of the Related Art In a railway vehicle using a linear motor as a driving means, the linear motor is formed in a flat shape so as to reduce the floor, and to secure a livability such as a ceiling height in the vehicle and cut off a passage. It is said that it is possible to correspond to a subway with a small area.

[0003] In this linear motor, it is necessary to keep a constant gap between the linear motor and a reaction plate installed on the ground side. Therefore, the linear motor must be mounted on a portion of the bogie that does not change between the track surface and the track. Conventionally, an axle has been used as such a portion.

However, since the axle is configured to be able to change in the horizontal direction and the vertical direction within a predetermined allowable range with respect to the bogie, the linear motor operates even when the axle is displaced. It is necessary to maintain a stable state, and a device for absorbing impact from the orbit is required. For this reason, there is a disadvantage that the structure for mounting the linear motor on the axle becomes complicated.

[0005] In order to solve such a drawback of the axle mounting method, a two-axle bogie is provided between two front and rear cross beams.
The linear motor is supported at three points by suspension links that are pin-supported to allow displacement in the front-rear direction, a regulating rod is mounted between the side beam and the linear motor via a spherical bush, and the linear motor and a bogie frame are provided. Alternatively, there has been proposed a mounting device for a linear motor of a bogie for a railway vehicle in which a support rod (a towbar) is attached to a joint portion with an elastic body interposed between swinging pillows (for example, Japanese Utility Model Laid-Open No. 1-128453). JP-A-10-4499
No. 3).

In this device, the traction force and the braking force are transmitted between the linear motor and the bogie frame by the support rod, and the positional relationship between the linear motor and the bogie frame in the left-right direction is regulated by the regulating rod. Has become.

[0007] Further, a pair of bogie frames each having a T-shaped side beam and a side beam are provided, and the ends of the side beams are mounted on the paired side beams, and are joined by a rubber bush or a ball head.
By absorbing the torsion of the track when passing through the transition curve, it is possible to prevent the loss of wheel load, and further increase the spring constant of the shaft spring and mount the linear motor on the bogie frame. Also, the configuration is such that the change in the gap between the linear motor and the reaction plate does not increase.

[0008]

However, if the rigidity of the shaft spring is increased in order to reduce the change in the gap between the linear motor and the reaction plate as in this device, the shaft spring as an original rail spring for a railway vehicle is used. The buffering action is impaired.

Further, in order to maintain the relationship between the linear motor and the bogie frame, there are many links for restricting the positional relationship in the front-rear and left-right directions. Therefore, consideration must be given to the rigid connection between the side beam and the side beam. Each displaceable joint between the side beam and the side beam is a portion that bears a large load. However, since a rubber bush or a ball head is used in this portion, there is a disadvantage in terms of maintenance.

The present invention provides a linear motor in which a linear motor can be mounted on a bogie frame while canceling the deflection of a shaft spring at the position of the linear motor, thereby maintaining the relationship between the linear motor and the reaction plate on the track side. An object of the present invention is to provide a bogie for a railway vehicle using the same.

[0011]

According to the present invention, a bogie for a railway vehicle using a linear motor according to the present invention includes a bogie frame having left and right side beams extending in the vehicle longitudinal direction and a lateral beam extending in the vehicle lateral direction. It is based on a railcar bogie, which is a two-axle bogie on which a motor is mounted, wherein the linear motor is supported by the side beam via a plurality of support members extending in the traveling direction of the vehicle, The shaft beam extending from the axle box supporting the axle is provided with first means for obtaining deflection information of the shaft spring, and based on the deflection information of the shaft spring obtained by the first means,
A second means for displacing the support member and canceling the deflection of the shaft spring at the linear motor support position is provided. The other end of the support member that supports the linear motor at one end has a certain degree of freedom in the longitudinal direction of the vehicle due to the elasticity of the coupling portion and the like, and has a geometrical error caused by vertical displacement or the like. It is desirable to be able to absorb.

According to this structure, the deflection information of the shaft spring is obtained by the first means, and the support member is displaced by the second means on the basis of the deflection information of the shaft spring. Despite being mounted on the bogie frame, the deflection of the shaft spring is offset at the linear motor support position.

Therefore, it is not necessary to increase the rigidity of the shaft spring in order to reduce the change in the gap between the linear motor and the reaction plate, so that the original function of the railway vehicle shaft spring for damping is not impaired. Also, in order to maintain the relationship between the linear motor and the bogie frame, there is no need to increase the number of links that restrict the positional relationship in the front-rear and left-right directions of the vehicle. No special strength considerations are required at the connection between the side beam and the side beam.

In order to do so, the first means is a spherical bearing provided on the shaft beam, and the second means connects the spherical bearing of the shaft beam and the support member. What is necessary is just to have the connection member which makes the said shaft beam and the said support member perform the same movement. Thus, in order to make the shaft beam and the support member perform the same movement, for example, as shown in FIG.
A position of length L2 from the front side of the shaft beam 101 of length L1,
What is necessary is just to make it connect with the position of length S2 from the front side of the support member 102 of length S1 with the connecting member 105 via the 1st and 2nd spherical bearings 103 and 104.
In this case, L1: L2 = S1: S2. By doing so, the movement of the shaft beam 101 and the movement of the support member 102 coincide with each other, that is, when the shaft beam 101 swings by the shake amount X, the support member 102 swings by the shake amount X ′ corresponding to the shake amount X. As a result, the deflection of the shaft spring can be offset at the position where the linear motor is supported, even though the linear motor is mounted on the bogie frame. In FIG. 1, the traction force and the braking force in the front-rear direction of the vehicle are transmitted by the support member 102. The restraint in the left-right direction of the vehicle is performed by the support member 102 and the connecting member 105.

In this case, as shown in FIG.
The shaft beam and the support member do not necessarily need to be arranged so as to be parallel. For example, as shown in FIG.
The first and second spherical bearings 103 'and 104' are used to connect the connecting portion 101a of the shaft beam 101 'with the connecting member 105' using the first and second spherical bearings 103 'and 104' so that the supporting member 1 'and the supporting member 102' do not have a parallel positional relationship. The shaft beam 101 'and the supporting member 102' may be connected to the connecting portion 102a of the supporting member 102 'so as to perform the same movement.

In such a case, the first means is a spherical bearing provided on the shaft beam, and the second means sets the other end of the support member to the other end of the shaft beam. It is also possible to position the shaft beam and the supporting member on the line connecting the shaft beam and the spherical bearing, and to make the same movement of the shaft beam and the support member.
For example, in FIG. 2, the tip P of the support member 102 ′ is disposed on a straight line Y connecting the front end of the shaft beam 101 ′ and the center of the connecting portion 101 a of the shaft beam 101 ′. If the supporting member moves in the same manner, the connecting member 105 'can be omitted.

Further, a connecting member for connecting the spherical bearings of the left and right shaft beams and another spherical bearing for connecting the connecting member to the supporting member are provided, and a connection between the supporting member and the connecting member of the supporting member is provided. A positional relationship with a point may correspond to a positional relationship between the shaft beam and a spherical bearing provided on the shaft beam.

Further, there is provided a connecting member for connecting the spherical bearings of the left and right shaft beams, wherein the supporting member is a supporting portion projecting from the connecting member and supporting the linear motor at a distal end portion, The first means is a spherical bearing provided on the shaft beam, and the second means is a projecting part projecting from the lateral beam, and the projecting part provided at a tip end of the projecting part. A bearing connecting the left and right spherical bearings, so that the line connecting the left and right spherical bearings corresponds to the positional relationship of the spherical bearings on the shaft beam, and It is also possible to omit the another spherical bearing by internally dividing the space between the two.

[0019]
