Embodiment Construction

[0017] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] Such as figure 1 As shown, the present invention includes a train system and a track system. Through the upper hinge device and the lower hinge device, three side-mounted empty rail vehicle bodies 7 are hinged and grouped into a train system. The track system is composed of track beam pillars 6, track beams 2 and overhead Composed of power supply rail 1, trains can be organized flexibly according to needs. The lower hinge device is a fixed hinge 4, which mainly restricts translation in three directions between the connected car bodies 7; Longitudinal translation makes the vehicles shake their heads when the train passes through the horizontal curve; the other is the free hinge 5, which mainly restricts the lateral translation between the connected car bodies 7, so that the vehicles can move freely when the train passes through the vertical curv...

Abstract

The invention provides an empty rail train car body and a track structure, belonging to the technical field of rail transportation. The left and right sides of the track beam with an H-shaped cross-section are vertical planes, and the upper and lower ends of the track beam are groove structures. The back of the car body is matched with the vertical plane of the track beam. The shaft of the upper guide wheel is parallel to the vertical groove edge, the upper part of the car body is supported by the upper guide wheel and the vertical plane inside the groove edge of the track beam, and the lower part is supported by the lower guide wheel equipped with a damping spring and the track beam The upper part of the car body is provided with a protruding suspension structure, and the suspension structure on the back of the car body is in contact with the plane of the groove of the track beam through the drive wheel arranged under the protruding structure, and the protruding structures at both ends of the car body There is a traction motor and its transmission system inside, and a longitudinal beam protruding from the bottom plane is provided under the car body. Vertical limit wheels are provided at both ends of the longitudinal beam, and lower limit wheels are provided in the middle and both ends.

Description

technical field [0001] The invention belongs to the technical field of rail transit, in particular to the technical field of empty rail train track systems. Background technique [0002] The side-mounted air rail train system has good performance and low cost. Compared with straddle monorail and suspended monorail, it can have smaller volume and higher space utilization of track beams. Existing monorail vehicles can only travel in one direction on the same track beam, such as straddle-type monorail trains, so the general line will be built with double lines to meet the two-way travel requirements of trains in two places. [0003] Existing monorail trains such as suspended monorail trains, because the bogie and the car body are separated and connected by the suspension system, so the distance from the track beam to the bogie and then to the car body is relatively large, and a relatively high track girder needs to be built to meet the requirements , which increases the diffic...
