Embodiment Construction

[0018] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] Such as figure 1 As shown, the side-mounted empty rail bogie of the present invention is mainly composed of bolsters 1 and the like. The bolster 1 is connected to the bogie frame 9 through a transverse spring 2, a vertical spring rod 3 and a traction rod 4, and each joint is hinged. The car body of the side-mounted empty rail vehicle is connected with the bolster 1, and the bogie is connected with the track through the transverse wheel 14 and the vertical wheel 13. Thus, the bogie system is the core of the entire side-mounted empty rail vehicle. The bogie in this example is mainly of welded construction. The frame 5 of the bogie is the basic structure of the bogie. Its structure is "I" shaped, mainly composed of two beams 5 arranged up and down and a longitudinal beam 10 in the center. Both ends of the beam 5 are equipped with vertical forks....

Abstract

The invention provides a side hanging type air rail train bogie, and belongs to the technical field of air rail transit vehicle engineering. A frame of the bogie is of an I-shaped structure. A crossbeam of the bogie is of a spindle-shaped structure with a waist in the middle portion, and vertical forks are arranged on the two ends of the crossbeam. A longitudinal beam is of a flat structure, and the left and right sides of the longitudinal beam are provided with an axle. The two ends of the axle and an axle box on the crossbeam are fixed through bearing bushes. The outer portion of the axle isprovided with a segmented outer axle and a gear transmission box. The axle in the gear transmission box is connected with the segmented outer axle through a bearing. A vibration damping mechanism isarranged in the middle portion of a vertical plane of the longitudinal beam. Two transverse springs are connected with a transverse spring mounting base in the center of a bolster. A pull rod supporting seat is arranged in the middle portion. One end of a vertical spring pull rod is fixed with the longitudinal beam through a vertical pull rod supporting seat, and the other end of the vertical spring pull rod is connected with the vertical pull rod supporting seat in the inner side of the bolster. The leg in the middle portion of the bolster is connected with one end of a longitudinal pull rodin a pin mode through a pin shaft, and the pulling power of a pulling motor is connected with a lateral wheel on the outer axle by the gear transmission box.

Description

technical field [0001] The invention belongs to the technical field of aerial rail transit vehicle engineering. Background technique [0002] The side-mounted empty rail train system has good performance and low cost. Compared with the straddle type empty rail and the suspension type empty rail, it can have a smaller volume and a higher space utilization rate of the track beam. Existing empty rail vehicles can only run vehicles in one direction at the same time on the same track, so its operation needs to build two-way lines, thus requiring more space to meet the two-way operation of empty rail vehicles. [0003] Existing air-rail trains, such as suspension-type air-rail trains, use a suspension system to connect the bogie and the car body because the bogie is separated, so the distance from the track beam to the bogie and then to the car body is relatively large, and it is necessary to build a relatively high track beam to To meet the requirements, this increases the const...
