Problems solved by technology

[0003] At present, the dual-axle bogies of straddle-type monorail trains generally transmit the traction force to the car body by setting traction rubber stacks, but the use of traction rubber stacks usually makes it difficult to match the vertical and lateral stiffness parameters between the car body and the bogie , which is not conducive to easing the vibration of the car body. Therefore, how to improve the double-axle bogie of the straddle monorail train so that the vertical stiffness and transverse stiffness between the car body and the bogie are not affected by the traction device, so that it is easy to adjust the two axles. It has become a technical problem to be solved urgently by those skilled in the art to perform parameter matching on elastic elements such as tie springs and lateral stoppers to improve the ride comfort of the vehicle.

Embodiment 1

[0027] see Figure 1 ~ Figure 3 , figure 1 It is a schematic layout diagram of a double-axle bogie used for a straddle-type monorail train provided by Embodiment 1 of the present invention; figure 2 yes figure 1 is a top view; image 3 yes figure 2 Middle A-A sectional view.

[0028] The double-axle bogie provided by Embodiment 1 includes a car body connection device 4 installed above the beam (not marked in the figure) of the frame body 2. The car body connection device 4 includes a traction pin 41 for fixed connection with the car body. The pin seat 42 on which the traction pin 41 is installed and the traction rod 43 arranged at both ends of the pin seat 42 are connected to the frame body 2 and the pin seat 42 through rubber joints at both ends of the traction rod 43 .

[0029] The traction pin 41 is installed on the pin seat 42 through the sliding bearing 45, and the upper end of the traction pin 41 is fixedly connected with the vehicle body, and the longitudinal for...

Embodiment 2

[0041] The difference between the second embodiment and the first embodiment is that the installation structure between the driving device 6 and the frame body 2 is different. In the second embodiment, in order to install the driving device 6 on the frame body 2, the gear box 62 is provided with Match the flange with the side surface of the arched side beam 23, and fix the driving device 6 to the arched side beam 23 through the installation hole on the flange.

[0042] The present invention also provides a straddle-type monorail train, which includes the double-axle bogie disclosed in the above embodiments. Since the double-axle bogie disclosed in the above-mentioned embodiment has the above-mentioned technical effect, the straddle-type monorail train having the double-axle bogie also has the above-mentioned technical effect, and will not be repeated here.

Abstract

The invention discloses a straddle typemonorail train and a double-shaft bogie thereof. The double-shaft bogie comprises a train body connecting device (4) installed above a cross beam of a frameworkbody (2), wherein the train body connecting device (4) comprises a traction pin (41) fixedly connected with a train body, a pin base (42) for installing the traction pin (41) and traction pull rods (43) arranged at two ends of the pin base (42), and two ends of each of the traction pull rods (43) are connected with the framework body (2) and the pin base (42) respectively through rubber nodes. Thedouble-shaft bogie can make the vertical rigidity and transverse rigidity between the train body and the bogie not affected by the traction rods, accordingly a user can obtain good running quality ofthe straddle typemonorail train by setting reasonable secondary spring rigidity parameters.

Description

technical field [0001] The invention relates to the technical field of monorail trains, in particular to a straddle-type monorail train and a double-axle bogie. Background technique [0002] For straddle-type monorail traffic, vehicles run on a single track beam. The track beam is generally reinforced concrete or steel structure. The track construction occupies less ground resources and has strong terrain adaptability. Monorail transportation has unique advantages such as large climbing ability, small turning radius, short construction period, and low cost. It has room for further promotion and wide application, and can effectively alleviate urban traffic congestion. [0003] At present, the dual-axle bogies of straddle-type monorail trains generally transmit the traction force to the car body by setting traction rubber stacks, but the use of traction rubber stacks usually makes it difficult to match the vertical and lateral stiffness parameters between the car body and the ...
