Description

  The present invention relates to a axle load compensation mechanism for a railway power vehicle.

For example, in the case of a normal electric locomotive, a load of 16.8 t is applied to each axle of a railway power vehicle. For this reason, there is a problem that an axle load drop occurs with the gravitational movement of the vehicle on an ascending slope (uphill) or downhill (downhill).
None

  Usually, railroad cars operate on a rough road with uphill or downhill as well as flat ground.

  In such a case, for example, as shown in FIG. 4, when the railway vehicle 101 climbs the climbing slope track 102, that is, in the case of climbing (when the head of the vehicle 101 is on the A side), the front of the vehicle is When the railway vehicle 101 descends the down-gradient track 102, that is, when it is a downhill (when the top of the vehicle 101 is on the B side), the rear of the vehicle body is lifted by the axial load movement, and is adhered to the wheel 104 that has lost the axial weight. There was a problem that gliding and slipping occurred due to lack. Therefore, some locomotives dedicated to the single slope section have been equipped with measures such as equip- ment with counterweights. In FIG. 4, 103 and 106 denote carts, and 105 denotes the other wheel.

  In view of the above situation, the present invention detects a tilt with respect to the traveling direction of a railway-powered vehicle, and prevents a shaft weight from being lost by moving the floor of the railway-powered vehicle with respect to the traveling direction of a heavy object. An object is to provide a double compensation mechanism.

In order to achieve the above object, the present invention provides

It is moved forward, and when the railway powered vehicle is in a downward slope, the heavy object is moved rearward of the railway powered vehicle.

  [2] In the axle load compensation mechanism for a railway powered vehicle according to claim 1, a recess is formed in a floor portion of the railway powered vehicle, the heavy object is disposed in the recess, and the center of gravity of the railway powered vehicle is further increased. It is characterized by lowering.

  [3] The rail load compensation mechanism for a railway powered vehicle according to [1] or [2], wherein the heavy object is equipment to be disposed in the railway powered vehicle.

  [4] In the axle load compensation mechanism for railway-powered vehicles described in [1] above, the detection information from the detection means is gradient point information that the vehicle has.

  [5] In the axle load compensation mechanism for railway-powered vehicles described in [1] above, the detection means is an air spring pressure sensor disposed on a carriage of the vehicle.

  [6] In the axle load compensation mechanism for a railway powered vehicle, a fluid ballast disposed on the floor of the railway powered vehicle, a drive device capable of moving the load of the fluid ballast forward and backward of the railway powered vehicle, and the railway power Detection means for detecting an inclination state with respect to the traveling direction of the vehicle, and driving the driving device based on the detection means, and when the railway powered vehicle is on an ascending slope, the load of the fluid ballast is in front of the railway powered vehicle. When the railway powered vehicle is in a downward slope, it is moved to the rear of the railway powered vehicle.

  According to the present invention, the following effects can be achieved.

  When the railway powered vehicle moves up the slope, the heavy object is moved forward of the railway powered vehicle, and when the railway powered vehicle moves down, the heavy object is moved rearward of the railway powered vehicle. Axial weight loss can be prevented.

The present invention relates to the driving force and control caused by inertial force (traction load) at the time of climbing and descending of a railway powered vehicle having power such as an electric locomotive, a diesel locomotive, a train, and a diesel train, and the loss of shaft weight due to gravity. The present invention provides a rail load compensation mechanism for a railway powered vehicle for suppressing power reduction.

  Hereinafter, embodiments of the present invention will be described in detail.

  FIG. 1 is a schematic diagram of a rail load compensation mechanism for a railway powered vehicle showing a first embodiment of the present invention, and FIG. 1 (a) shows the overall configuration in the case of a flat railway track. FIG. 1B shows the case of a railroad track with an uphill (uphill gradient), and FIG. 1C shows the case of a railroad track with a downhill (downhill gradient).

  In FIG. 1A, 1 is a railway-powered vehicle, 2 is a floor of the vehicle 1, 3 is a heavy object, 4 is a drive motor, 5 is a drive rod for moving the heavy object 3, and 6 is a front side. , 7 is a rear vehicle, 8 is a front wheel, 9 is a rear wheel, 11 is an air spring pressure sensor disposed on the front vehicle 6, and 12 is an air spring pressure sensor disposed on the rear vehicle 7. , 13 is a control device, and at least gradient point information 14, information 15 from the air spring pressure sensors 11, 12, power running command (mascon) information 16, and brake command (brake handle) information 17 are taken into this control device 13. Accordingly, the drive motor 4 is driven in accordance with the gradient, and the heavy article 3 is moved back and forth by driving the drive rod 5.

  In addition, the equipment of a railway power vehicle can be used as the heavy article 3 (for example, a variable resistor, a dead weight block, a free wheel, a fuel cell, a battery, an inverter, etc.).

  For example, as shown in FIG. 1 (b), in the case of a railway track with an uphill gradient, a phenomenon of axle weight loss of the wheel 8 in front of the railway powered vehicle 1 appears. Therefore, in order to avoid this, the heavy load 3 is moved to the front of the railway powered vehicle 1, so that the axle weight of the wheel 8 in front of the railway powered vehicle 1 can be prevented from coming off.

  In addition, as shown in FIG. 1C, in the case of a railway track with a downward slope, a phenomenon of shaft weight loss of the wheel 9 behind the railway powered vehicle 1 appears. Therefore, in order to avoid this, by moving the heavy object 3 to the rear of the railway powered vehicle 1, it is possible to prevent the axle 9 from coming off the rear wheel 9 of the railway powered vehicle 1.

  In addition, in the said Example, although the movement of the heavy article was described, as shown in FIG. 2, the drive apparatus 22 was driven based on the information from the control apparatus 21 corresponding to the inclination of a railway power vehicle, The working fluid ballast 23 is tilted about the support portion 24, and fluid is collected in front of the working fluid ballast 23 in an ascending gradient, and fluid is collected in the rear of the working fluid ballast 23 in a descending gradient. Also good.

Here, as the heavy object 34, a variable resistor (a variable resistor to which a flexible and extendable cable is connected) which is one of the facilities of a railway powered vehicle can be used. In addition, other railway-powered vehicle equipment may be dead weight, free wheel, fuel cell, battery, inverter, and the like.

  As described above, since the heavy load 34 is arranged in the one step lower recess 33 of the floor portion 32 of the railway powered vehicle 31, the center of gravity of the railway powered vehicle 31 becomes lower. Stability can be increased.

  Moreover, since the variable resistor 33 which is one of the facilities of a railway power vehicle is used as a heavy article, cost can be reduced.

  Further, the movement adjustment of the heavy object can be accurately performed based on the gradient point information taken into the control device of the vehicle.

  Further, since the movement adjustment of the heavy object can be performed based on information from the air spring pressure sensor disposed on the carriage of the vehicle, an accurate adjustment according to the vehicle can be performed.

  Since it comprised in this way, the reduction of the driving force and braking force by a shaft weight omission can be suppressed also at the time of the uphill / downhill of a railway power vehicle.

  In addition, this invention is not limited to the said Example, Based on the meaning of this invention, a various deformation | transformation is possible and these are not excluded from the scope of the present invention.
