[0007] The purpose of the present invention is to solve the deficiencies in the above-mentioned background technology and to provide a central suspension device for a bogie used in an aerial rail transportation vehicle.

[0008] The technical solution adopted by the utility model is: a central suspension device of a bogie for an aerial rail transportation vehicle, comprising a center pin, an upper round pin, a lower round pin, and a bolster, wherein the lower portion of the center pin passes through the vehicle body and the bolster, the upper portion of the center pin is connected to the frame through the upper round pin, and the lower portion of the center pin is connected to the bolster through the lower round pin.

[0009] In a further preferred structure, secondary rubber springs are provided at the four corners of the upper end of the bolster, the upper ends of the secondary rubber springs are in contact with the vehicle body, and the lower ends of the secondary rubber springs are fixed to the bolster.

[0010] A further preferred structure further includes a traction rod and a hydraulic shock absorber for connecting the vehicle body and the frame, wherein both ends of the traction rod are connected to the vehicle body and the frame respectively, and both ends of the hydraulic shock absorber are connected to the vehicle body and the frame respectively.

[0011] A further preferred structure also includes a roll stopper, which is installed at the bottom of the frame. The upper end of the roll stopper is fixed to the bottom of the frame. When the vehicle body rolls to a limited angle, the lower end of the roll stopper contacts the vehicle body to limit the vehicle body from continuing to roll.

[0012] In a further preferred structure, transverse stops are provided on both sides of the bolster, and when the vehicle body is displaced too much laterally relative to the bolster, the outer ends of the transverse stops come into contact with the vehicle body.

[0013] In a further preferred structure, the upper round pin passes longitudinally through the upper part of the center pin, and the frame is fixed to both ends of the upper round pin.

[0014] In a further preferred structure, the lower round pin passes longitudinally through the lower portion of the center pin and the bolster, connecting the bolster to the center pin.

[0015] In a further preferred structure, the upper round pin and the lower round pin are respectively perpendicular to the center pin.

[0016] In a further preferred structure, the center pin, the upper round pin and the lower round pin are forgings, and the bolster is a steel plate welded part.

[0017] The utility model also provides a bogie for an aerial rail transport vehicle, comprising the central suspension device.

[0018] The utility model has the following beneficial effects:

[0019] 1. The utility model provides a strong connection between the vehicle body and the bolster. At the same time, the vertical relationship between the upper and lower round pins helps to share loads in different directions, improving the stability of the overall structure. The use of pin connection can not only transmit longitudinal forces, but also effectively withstand forces from the lateral or vertical directions, preventing slippage between components. The pin design is easy to disassemble, maintain and replace, reducing the impact on the entire vehicle structure and saving maintenance costs.

[0020] 2. The rubber spring of this utility model can effectively absorb the vibration and impact generated during the operation of the vehicle body, reduce the load on the vehicle body and frame, and improve stability and comfort; the cushioning effect of the rubber spring can make the dynamic response of the vehicle body at different speeds more stable, and reduce the impact of excessive vibration on the vehicle body and passengers; the design of the rubber spring enables it to adjust its elasticity according to different loads and operating conditions, adapting to different working environments.

[0021] 3. The traction rod of the utility model effectively transmits the traction force between the vehicle body and the frame, while avoiding excessive movement between the vehicle body and the frame, and maintaining the stability of the overall structure; the hydraulic shock absorber can effectively reduce the vibration caused by uneven roads or other external factors, increase the smoothness of driving, and reduce the damage to the vehicle and its components; the shock absorber can significantly improve the safety of the vehicle during high-speed or intense operations, and reduce the risk of loss of control caused by vibration.

[0022] 4. The design of the roll stop of the utility model effectively limits excessive lateral tilt or rolling of the vehicle body, especially in sharp turns or uneven roads, which can prevent the vehicle body from dangerously tilting or overturning, ensuring driving safety; by limiting the roll, the vehicle's controllability is enhanced, avoiding driving instability caused by excessive lateral tilt.

[0023] 5. The lateral stop of the utility model can prevent the lateral displacement of the vehicle body caused by external forces (such as collisions, crosswinds, etc.) during driving, thereby enhancing the lateral stability of the vehicle; when the vehicle is impacted by external forces, the lateral stop can effectively limit the movement of the vehicle body and reduce the risk of accidents; by reducing the relative movement between the vehicle body and the bolster, the lateral stop can also reduce wear between the structures and extend the service life of the vehicle.

[0024] 6. The design of the round pins of the utility model makes the force transmission between the connection points more uniform and efficient, avoiding the loosening or falling off problems that may be caused by traditional bolt connections; since the round pins are usually forged, they have a strong load-bearing capacity and are suitable for bearing large tensile forces, shear forces and bending moments, thereby improving the strength of the entire connection structure; the vertical design of the upper and lower round pins can reduce the deviation caused by vibration or impact, and enhance the stability of the overall connection.
