ものが知られている。2. Description of the Related Art In order to prevent a vehicle from traveling in a curved track at a high speed and to prevent deterioration of riding comfort due to centrifugal force, a pendulum beam of a bogie is utilized by means of a roller or a link using a centrifugal force called a natural pendulum type. With a vehicle body inclining mechanism for inclining, or with a fluid actuating mechanism for forcibly imparting to the vehicle body an inclination suitable for the vehicle speed in a curved track, the radius of curvature, and the amount of cant in the pendulum beam, or It is known that the air of a pair of left and right air springs arranged between a vehicle body and a carriage is supplied and exhausted to expand and contract to directly incline the vehicle body.

のがある。Among these, for example, Japanese Patent Publication No. 62-34
As disclosed in Japanese Patent No. 579, a pair of left and right air springs and a hydraulic cylinder as a fluid actuating mechanism are arranged in parallel between a vehicle body and a bogie, and the hydraulic cylinder is expanded and contracted based on an output signal of an acceleration detector. There are those that perform tilt control and vibration control.

と車体との間に左右一対のヨーダンパを配設している。Further, conventionally, the position in the front-rear direction between this type of vehicle body tilt control bogie and the vehicle body is regulated by a single link, and the lateral direction is regulated by a center pin and a stopper rubber or the like. A pair of left and right yaw dampers are arranged between the carriage and the vehicle body in order to prevent the meandering.

数が変化し、乗り心地に影響を与える。However, in a pendulum type vehicle body tilting mechanism having a pendulum beam, since a pendulum beam, rollers, links and the like are used, the structure is complicated and the weight is heavy and the tilt angle cannot be large. In addition, in the vehicle body tilting mechanism that adjusts the height of the pair of left and right air springs, air supply and exhaust of the air springs are repeated every time the vehicle body tilts, so air consumption increases and the vehicle body tilts. The spring constants of the left and right air springs change, which affects riding comfort.

た。Further, due to the inclination of the vehicle body, the fulcrum of the hydraulic cylinder provided between the bogie and the vehicle body makes an arc motion, and a lateral force is generated at the fulcrum of the hydraulic cylinder by the arc motion, so that the bogie is turned. Along with the accompanying twisting, the result is that the hydraulic cylinder is twisted, and there is a problem that the movement of the hydraulic cylinder is hindered or the life is shortened.

ことが困難であった。Further, since the yaw damper disposed between the bogie and the vehicle body is lifted on one side of the vehicle body when the vehicle body is tilted, a large stroke due to the difference in height between the left and right is required, and the total length of the yaw damper is increased. Since it becomes longer, it is difficult to increase the supporting rigidity.

An object of the present invention is to provide a vehicle body support structure for a vehicle body leaning control bogie that stabilizes the operation of the vehicle body leaning fluid actuation mechanism and improves durability.

としている。In order to achieve the above-mentioned object, the vehicle body tilting control vehicle body supporting structure of the present invention is, in the invention of claim 1, a pair of left and right fluid body actuating mechanisms for leaning between the vehicle body and the vehicle body. A vehicle body tilt control carriage for extending the vehicle body tilting by extending one of the vehicle body tilting fluid actuating mechanisms, and providing a vehicle body support beam supported by a pillow spring at the center of the vehicle body. The fluid actuating mechanism for leaning a vehicle body is arranged on a support beam, and the invention is also characterized in that

響によって枕ばねのばね定数が変化しない。According to the above configuration, in the invention of claim 1, the vehicle body can be tilted by either one of the left and right vehicle body tilting fluid actuating mechanisms arranged on the vehicle body support beam supported by the pillow spring. Since the vehicle body supporting beam itself is not tilted and remains parallel to the bogie, the spring constant of the pillow spring does not change due to the effect of tilting.

って左右方向の位置をそれぞれ規制されて、平行で一体
的結合状態のまま同一運動を行う。According to the second aspect of the present invention, when the vehicle is traveling on a straight road, both the left and right vehicle body inclining hydraulic cylinders are contracted. Therefore, the vehicle body and the vehicle body support beam are positioned in the front-rear direction by a pair of left and right links. The left and right positions are regulated by the pair of left and right stopper devices, and the same motion is performed in a parallel and integrally coupled state.

平行状態を保ち、車体と車体支持梁とは、車体傾斜用油
圧シリンダの収縮側のストッパ装置によって直線路走行
時と同様に左右方向の位置を規制する。When one of the vehicle body tilting hydraulic cylinders is extended to tilt the vehicle body while the vehicle is traveling on a curved road, the vehicle body supporting beam itself is not tilted and is kept parallel to the bogie. The positions of the vehicle body support beam and the vehicle body support beam in the left-right direction are regulated by a stopper device on the contraction side of the vehicle body tilting hydraulic cylinder as in the case of traveling on a straight road.

円弧運動によって僅かに前後方向へ移動する。The positions of the vehicle body and the vehicle body support beam in the front-rear direction are restricted by the link on the contracting side in the same manner as when traveling on a straight road so that the vehicle body inclining hydraulic cylinder is extended. That side is regulated by the link on the extension side. At that time, the vehicle body support beam slightly moves in the front-rear direction due to the arc movement of the extension side link.

トロールが容易に行え、乗り心地が向上する。As described above, in the vehicle body support structure for a vehicle body tilt control bogie of the present invention, in the invention of claim 1, a vehicle body support beam supported by a pillow spring is provided at the center of the bogie,
Since a pair of left and right fluid actuating mechanisms for leaning the vehicle body are provided on the vehicle body supporting beam, the vehicle body supporting structure can be simplified, and the vehicle body leaning is provided on the vehicle body supporting beam supported by the pillow spring. This is done by extending one of the left and right body tilting fluid actuating mechanisms, and the body supporting beams themselves remain parallel to the bogie without tilting, so the spring constant of the pillow spring changes due to the effect of body tilting. Instead, the vehicle body tilt control can be easily controlled and the riding comfort is improved.

と同様に左右方向の位置を規制する。According to the second aspect of the present invention, a hydraulic cylinder is used as the fluid actuating mechanism for leaning the vehicle body of the first aspect, and a pair of left and right links are provided between the vehicle body and the vehicle body supporting beam to regulate the longitudinal position of the vehicle body supporting beam. Since a pair of left and right stopper devices that restrict the position in the left-right direction when the vehicle body tilt hydraulic cylinder is contracted are provided, both the left and right vehicle body tilt hydraulic cylinders are contracted when the vehicle is traveling on a straight road. The position of the vehicle body support beam in the front-rear direction is restricted by a pair of left and right links, and the position in the left-right direction is restricted by a pair of left and right stopper devices. When traveling on a curved road, even if either of the vehicle body tilting hydraulic cylinders is extended to tilt the vehicle body, the vehicle body support beam itself does not tilt and remains parallel to the bogie. , The vehicle body and the vehicle body support beam, contraction side of the stopper device of the vehicle body tilt hydraulic cylinder for regulating the position in the horizontal direction similarly to the straight road running.

動する。On the other hand, regarding the positions of the vehicle body and the vehicle body supporting beam in the front-rear direction, the contracted side of the vehicle body tilting hydraulic cylinder is regulated by the link on the contracted side in the front-rear direction in the same manner as when traveling on a straight road so that the vehicle body tilts. The extended side of the hydraulic cylinder for use is restricted by the link on the extended side. At that time, the vehicle body support beam slightly moves in the front-rear direction due to the arc movement of the extension side link.

効に防止できる。According to the third aspect of the present invention, since the yaw damper is arranged between the bogie frame of the bogie and the vehicle body supporting beam, the yaw damper is not affected by the inclination of the vehicle body, and the total length of the yaw damper can be shortened to increase the supporting rigidity. It is possible to effectively prevent snakes from moving at high speed.
