Description

Technical Field

[0001] This utility model relates to the field of friction line technology, specifically a friction line large-amplitude oscillation drive device. Background Technology

[0002] Existing friction tracks typically employ a curved section friction drive device when transporting train sets across horizontal curved tracks. This device mounts both the drive and driven wheels on a single swing frame, allowing both wheels to swing with the frame as a whole. However, the swing angle is limited by the frame structure itself. When track layout requires two consecutive 90° horizontal curves without a straight section connecting them, if the train set's connecting rod length reaches 2 meters, the existing curved section drive device's swing angle cannot meet the passage requirements, and it can also cause interference between the drive frame and the track structure. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a friction line large swing drive device with a large swing amplitude, which can adapt to the smooth passage of long-pitch train connecting rods through two consecutive 90° horizontal curved rails without straight sections in between.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a friction line large swing amplitude driving device, including a fixed frame, and further including a driving component, a driven component, and a connecting rod assembly; the driving component includes a first swing arm, which is rotatably disposed at the near end of the fixed frame and connected to a driving wheel; the driven component includes a second swing arm, which is rotatably disposed at the far end of the fixed frame and connected to a driven wheel; the connecting rod assembly includes a transmission connecting rod, which is connected to the first swing arm through a clamp, and the far end of the transmission connecting rod is hinged to the second swing arm through a connecting arm.

[0005] A further improvement is that: a support frame is connected to the proximal end of the clamp, the middle part of the transmission link is fixedly connected to the clamp, the proximal end of the transmission link moves through the support frame, and a return spring is sleeved on the part of the transmission link located inside the support frame.

[0006] A further improvement is that the support frame has a horizontally arranged L-shaped structure, and a spring seat is provided inside the support frame; the transmission link moves through the spring seat, and one end of the return spring abuts against the spring seat, while the other end of the return spring abuts against the clamp.

[0007] A further improvement is that the spring seat is equipped with an adjusting nut for adjusting the compression of the return spring.

[0008] A further improvement is that the first swing arm is provided with a mounting plate, and the mounting plate is provided with a torsion spring and a limiting pin adapted to the torsion spring, so as to return the first swing arm to the initial position.

[0009] A further improvement is that a hinge seat is provided on the mounting plate, and the clamp is hinged to the hinge seat.

[0010] A further improvement is that the fixed frame has a gate-shaped structure, including a crossbeam and two columns, with support plates respectively provided at the upper and lower ends of the columns; the first swing arm is hinged to the corresponding two support plates through a first pivot, and the second swing arm is hinged to the corresponding two support plates through a second pivot.

[0011] A further improvement is that the lower end of the first swing arm is connected to a first tilting arm, and the end of the first tilting arm is connected to the drive wheel through a first wheel seat.

[0012] A further improvement is that the first wheel seat has a horizontal U-shaped structure, and a motor for driving the drive wheel to rotate is provided on the first wheel seat.

[0013] A further improvement is that the lower end of the second swing arm is connected to a second tilting arm, and the end of the second tilting arm is connected to the driven wheel through a second wheel seat.

[0014] The beneficial effects of this utility model are as follows: 1. This utility model breaks through the angle limitations of traditional integral swing frames by setting the drive wheel and driven wheel on the independently rotatable first and second swing arms respectively, and using a linkage assembly to achieve their linkage. This structure enables the drive wheel and driven wheel to achieve a wider range of misaligned swing, thereby significantly improving the overall swing amplitude and adapting to the operation requirements of long-pitch trainsets in complex curved tracks.

[0015] 2. This utility model, through the design of a separate swing arm and the flexible connection mechanism of the transmission link, enables the driving wheel and the driven wheel to adjust the swing angle autonomously according to the curvature of the curved track, effectively avoiding structural interference and ensuring a smooth transition of the train set.
