Summary of the Invention
Problem to be Solved by the Invention [0005] When a bogie is lifted by a crane or the like for such as carrying the bogie, it is desirable that an axle box rotatably supporting a wheel axle having a pair of wheels at both ends of an axle should not be separated from a bogie frame. Further, in recent years, in order to enhance safety when a railway vehicle passes through a curve with a relatively small radius of curvature, it is required to manage a wheel load ratio which is a ratio of loads of left and right wheels pressing rails. In order to manage this wheel load ratio, there is a need for a structure in which, between a bogie frame constituting a bogie and each of axle boxes supported by the bogie r frame, a height adjustment plate capable of adjusting a distance between the bogie frame and a wheel axle can be easy inserted.
[0006] It is an object of the present invention to provide a railway vehicle bogie having a structure that can prevent falhng-off of an axle box from a bogie frame when the bogie is lifted, and in addition, that can easily adjust a whe& load ratio.
Means for solving the Problems [0007] A raUway vehicle bogie of the present inventbn includes a side beam forming a bogie frame: an axle box rotatably holding a wheel axle; and an axle spring disposed between the side beam and the axle box] wherein the axle spring is composed of a cylindrical axle spring upper part: a beft-shaped axle spring lower part; and an elastic body disposed between the axle spring upper part and the axle spring lower part.
Further] the railway vehicle hogie including a connecting member passing through the axle spring so as to connect the side beam and the axle box to each other includes an axle spring lower seat disposed between the axle spring lower part and the axle box; a flange provided at a peripheral portion of a lower surface of the axle spring lower seat; a planar axle box upper end surface provided at an upper portion of the axle box, the flange adapted to abut against the axle box upper end surface; and a height adjustment plate disposed between the flange and the axle box upper end surface and adapted to adjust a wheel load ratio.
Advantageous Effect of the Invention [0008] According to the present invention, it is possible to provide a railway vehicle bogie having a structure that can prevent falling-off of an axle box from a bogie frame, and in addition, that can easily adjust a wheel load ratio.

[0009] FIG. 1 is a top view of a railway vehicle bogie.
FIG. 2 is an A-A sectional view of a side beam forming a bogie frame.
FIG. 3 is a sectional view (A-A section of FIG. 2) of an axle box provided with a falling-off prevention mechanism and a height adjustment mechanism.
FIG. 4 is a sectional view showing a state where the fallingoff prevention mechanism has functioned.
Modes for carrying out the Invention [0010] Hereinbelow, a mode for carrying out the present invention will be described with reference to the drawings.
[0011] FIG. 1 is a top view of a railway vehicle bogie. A railway vehicle bogie 1 is an inner frame type bogie of a mode in which wheel axles having a total of four wheels 240 at both ends of two axles 230 are disposed on an inner side of side beams 10 (on the raway central side or at a central portion in a longitudinal direction of the axles 230) forming a bogie frame 5. The wheel axles are provided on lower sides of both end portions in a longitudinal direction of the side beams 10 via axle boxes 64 rotatably holding the wheel axles.
[0012] The bogie frame 5 includes the side beams 10 spaced apart in parallel from each other, air spring receiving bases 50 each disposed on an outer side of the side beam 10 (in a direction away from the raHway center) with its longitudinal direction being parallel to the side beam 10, and transverse beams 20 each passing through the side beams 10 and the air spring receiving bases 50 at their longitudinal direction central portions. Each transverse beam 20 is joined to the side beams 10 and the air spring receiving bases 50 by welding. When seen from above, the bogie frame 5 has a generally H-shape.
[0013] An air spring 210 is attached to an upper surface of the longitudinal direction central porton of each air spring receiving base 50 via an air spring mounting seat. The air springs 210 support the weight of a vehicle body (not illustrated), in order to suppress yawing (oscillation in a horizontal plane about a bogie center pin (not illustrated) as a rotation center) of the bogie 1 during high speed running, a yaw damper 200 is provided so as to couple between a yaw damper receiver provided to a side surface of the central portion of each air spring receiving base 50 and the vehicle body (not illustrated).
[0014] Brake devices 56 are provided at both ends in the longitudinal direction of each air spring receiving base 50. At the time of braking, brake shoes of each brake device 56 clamp brake discs (not illustrated) provided to both side surfaces of the wheel 240, thereby obtaining braking force.
[0015] The structure of the railway vehicle bogie has been described exemplifying the inner frame type bogie 1 with disk brakes. However, a falling-off prevention mechanism and a height adjustment mechan!sm which will be described in deta!l hereinbelow are not limited to the bogie described in FIG. 1 and can also be applied to an outer frame type bogie or a bogie with tread brakes.
[0016] FIG. 2 is an A-A sectional view of a side beam forming a bogie frame and FIG. 3 is a sectional view (A-A section of FIG. 2) of an axle box provided with a falling-off prevention mechanism and a height adjustment mechanism.
[0017] Side beam end portions 12 open downward are provided at both ends in the longitudinal direction of each side beam 10 forming the bogie frameS. Each axle box 64 is elastically supported by the side beam end portion 12 via an axle spring lower seat 68 disposed at an upper end of the axle box 64, an axle spring 70 filled around the axle spring lower seat 68, and a hanging metal fitting 80 disposed at an upper end of the axle spring 70.
[0018] The axle box 64 is provided, at its portion closer to the longitudinal direction central portion of the side beam 10, with an axle box side protrusion 64c. The axle box side protrusion 64c and a side beam link receiver I Ob provided to the side beam are connected to each other via an axle box longitudinal link 62. The axle box longitudinal link 62 is provided with annular portions at both ends in a longitudinal direction thereof and has fixing portions oath at a central portion of a rubber filled in the annular portion. The fixing portions provided at both ends of the axle box longitudinal link 62 are coupled to the axle box side protrusion 64c and to the side beam link receiver I Ob so that the axle box 64 is elastically supported in the longitudinal direction of the side beam 10.
[0019] The axle spring 70 is composed of a cylindrical axle spring upper part 72 having an outer diameter of its lower portion set greater than that of its upper portion so as to bulge at its lower portion, a bell-shaped axle spring lower part 76, and an anti-vibration rubber 74 disposed between the axle spring upper part 72 and the axle spring lower part 76. The anti-vibration rubber 74 can be displaced in up-down, left-right, and front-rear directions and thus can be adapted to the displacement of the axle box 64 in these three directions. The anti-vibration rubber 74 is bonded to the axle spring upper part 72 and to the axle spring lower part 76 so as to be integrated together. The anti-vibration rubber 74 may have a cylindrical shape or the anti-vibration rubbers 74 may be discretely provided at positions so that the anti-vibration rubbers 74 face each other in the front-rear and left-right directions.
[0020] A hole I 2b through which the hanging metal fitting 80 is inserted is provided at a portion, where a central axis of the axle spring 70 crosses, of a top portion 12a of the side beam end portion 12. In addition, a recess 12c into which an upper end portion of the axle spring upper part 72 forming the axle spring 70 is fitted is provided on a lower surface of the top portion I 2a.
[0021] By providing the recess 12c, when fixing the axle spring 70 to the side beam end portion 12 provided so as to be open downward, the axle spring upper part 72 can be fitted into the recess 12c so that the axle spring 70 can be easily positioned. Further, since the axle spring upper part 72 is filled into the recess I 2c, when the axle box 64 is displaced in the left-right and front-rear directions, a vertical surface of the recess I 2c bears shear load generated between the top portion I 2a and the axle spring upper part 72 so that shear load applied to bolts 102 can be made small. Therefore, the bolt 102 of a small size can be selected and, in addition, the thickness of the axle spring upper part 72 into which the bolt 102 is inserted can -.5-also be made smafi. Accordingly, a reduction in the weight of the top portion 12a and the axle sphng 70 can be promoted by providing the recess 12c.
[0022] The hanging metal fitting 80 includes a cyUndrical member and a flange 80a extending radially from an upper end portion of the cylindrical member. An outer diameter of the cyUndrical member is set slightly smaller than an inner diameter of the hole 12b, while an outer diameter of the flange BOa is set greater than the inner diameter of the hole 12b. The hanging metal fitting 80 is connected to the axle box 64 via a bolt 100 such that the cylindrical member is inserted through the hole 12b with the flange BOa located above the top portion 1 2a and that a lower end portion of the cylindrical member is placed on a horizontal portion 76a of the axle spring lower part 76.
[0023] Since a gap G (see FIG. 3) is provided between a lower surface of the flange BOa and the Lop portion 12a, even if the axle spring 70 is vertically displaced relative to the side beam 10 due to railway irregularities or the like within a range in which the flange 80a of the hanging metal fitting 80 does not abut against the top portion 1 2a, there is no possibility of collision between the flange BOa and the top portion 12a and therefore the vertical displacement of the axle spring 70 relative to the side beam 10 is not inhibited.
[0024] The upper end portion of the axle spring upper part 72 forming the axle spring 70 is provided therein with threaded portions and the upper end portion of the axle spring upper part 72 is fitted into the recess 12c provided in the top portion 12a and is fixed to the top portion 12a by the bolts 102. The horizontal portion Tha is provided at an upper end of the axle spring lower part 76 forming the axle spring 70 and a hole through which the bolt 100 passes, which will he described later, is provided at a central portion of the horizontal portion 76a. The lower end portion of the cylindrical member of the hanging metal fitting 80 passing through the hole 12b is placed on an upper surface of the horizontal portion 76a.
[0025] On the other hand! an axle box upper end surface 64b forming a horizontal plane is provided at an upper end of the axle box 64 rotatably holding the wheel axle and a cyUndrical axle box upper protrusion 64a is provided so as to extend vertically upward from a central portion of the axle box upper end surface 64b. An upper end portion of the axle box upper protrusion 64a is provided Lherein with a screw seat (female screw). The bolt 100 passing through the hanging metal fitting 80 inserted through the hole 1 2b provided in the top plate I 2a, the axle spring lower part 76, and the axle spring lower seat 68 is screwed into the screw seat.
[0026] The beikshaped axle spring lower seat 68 s provided on an upper surface of the axle box upper end surface 64b. A flange 68a adapted to abut against the axle box upper end surface 64b is provided at a lower end of the axle spring lower seat 68.
In addition, a cyhndhcal space 68b is provided from a central poffion of the flange 68a along a central line of the axle spring lower seat 68. An nner diameter of the cylindrical space 68b is set slightly greater than an outer diameter of the axle box upper protrusion 64a.
[0027] When the axle spring lower seat 68 is placed above the axle box 64, a lower surface of the flange 68a is brought into contact with the axle box upper end surface 64b and the axle box upper protrusion 64a is fitted into the cylindrical space 68b.
[0028] When inserting a height adjustment plate 90 between the axle box upper end surface 64b and the lower surface of the flange GSa in order to maintain a wheel load ratio in a predetermined range, since the axle box upper protrusion 64a is fitted into the cylindrical space 68b, the axle box upper protrusion 64a can move vertically, being guided by the cylindrical space 68b, while maintaining the paraUelism between the axle box upper end surface 64b and the lower surface of the flange 68a. With this structure, even if the height adjustment plate 90 is inserted between the axle box upper end surface 64b and the lower surface of the flange 68a in order to allow a wheel cad ratio to fall within a predetermined range, there is no wobble of the axle box 64 or the axle spring lower seat 68.
[0029] FIG. 4 is a sectional view showing a state where the falling-off prevention rnecharusm has functioned. When moving the bogie 1, the bogie 1 is loaded on a truck or the like by attaching a wire to the bogie frame 5 and lifting the bogie frame 5 by a crane. When the side beams 10 forming the hogie frame 5 are lifted via the wire, since the axle boxes 64 hold the heavy wheel axles, the distance between each axle box 64 and the side beam 10 increases to reduce the gap G (see FIG. 3) so that, finally, the flange BOa abuts against the top portion 12a. Since the outer diameter of the flange SOa is set greater than the inner diameter of the hole 12b, the hanging metal fitting 80 never passes through the hole 1 2b. Therefore, the axle box 64 connected via the bolt 100 locked by the hanging metal fitting 80 never faUs off the bogie frame 5.
[0030] With the structure described above, it is possible to provide the railway vehicle hogie that exhibits the following effects, [0031] Even if the bogie frame 5 is lifted by a crane or the like when carrying the bogie 1, it is possible to prevent fallingoff of the axle box 64 from the bogie frame 5.
[0032] Further, by raising the axle spring lower seat 68, the height adjustment plate can be easily inserted between the axle spring lower seat 68 and the axle box 64 and, in addition, the occurrence of wobble due to the insertion of the height adjustment plate 90 can be suppressed.
[0033] Further, since the recess 1 2c is provided on the lower surface of the top porhon I 2a of the side beam end porflon 12, the position of the axle spring 70 can be easily determined even in a state where workabihty is poor.
[0034] Further, even if large load is apphed to the axle spring 70 in the frontrear and left-right directions due to the displacement of the axle box 64 in the front-rear arid left-right directions, the vertical surface of the recess 12c bears shear load generated between the top portion 12a and the axle spring upper part 72 so that shear load applied to the bolts 102 fixing the axle spring 70 to the side beam end portion 12 can be made small and, in addition, the thickness of the axle spring upper part 72 forming the axle spring 70 can he made small. Accordingly, a reduction in the weight of the axle spring 70 can be promoted.
