Description

Technical Field

[0001] The utility model belongs to the technical field of aerial sightseeing cars, and particularly relates to a differential type double-axis power bogie for an aerial sightseeing car. Background Art

[0002] The bogies of existing aerial sightseeing cars adopt the bogies of straddle-type monorails for urban rail transit. Its structure consists of running wheels, track beams, guide wheels, driving devices, etc. The running wheels and the driving device are directly connected on one side to form a single-arm driving system. Due to the certain weight of the driving device, serious eccentric wear occurs on the side of the running wheel close to the driving device, greatly shortening the service life of the running wheel. At the same time, when passing through a curve, a large rotational friction force is generated between the running wheel and the track beam, greatly reducing the mechanical transmission efficiency. The eccentric wear of the running wheel can also cause the eccentric wear of the guide wheel, also shortening the service life of the guide wheel, increasing the frequency of wheel replacement and maintenance costs to a certain extent. Therefore, there is an urgent need for a differential type double-axis power bogie for an aerial sightseeing car to solve the above problems. Summary of the Utility Model

[0003] Aiming at the problems raised in the above background art, the purpose of the utility model is to provide a differential type double-axis power bogie for an aerial sightseeing car.

[0004] To achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0005] A differential type double-axis power bogie for an aerial sightseeing car, including a bogie frame. Mounting seats are installed on the front and rear sides of the bottom of the bogie frame.

The power output end of the traction motor is connected to the differential gearbox. The power output ends on both sides of the differential gearbox are connected to running wheels. Auxiliary frames arranged in a cross-shaped structure are installed on the left and right sides of the bogie frame. Guide wheels are installed on the front and rear sides of the auxiliary frame. A stabilizer wheel is installed at the bottom of the auxiliary frame.

[0006] Further defined, a brake is installed on the outside of the running wheel. Such a structural design can directly brake the running wheel and improve the braking effect.

[0007] Further defined, a lifting ring is installed on the top outside of the traction motor. The lifting ring is connected to a suspension rope. The other side of the suspension rope is connected to a suspension seat. The suspension seat is installed on the bogie frame. Such a structural design can play a role in pulling up the traction motor and prevent the traction motor from tilting after long-term use.

[0008] Further defined, the differential gearbox is arranged at the middle position of the bogie frame, and the traction motor is installed at the middle of the differential gearbox. Such a structural design makes the center of gravity of the entire bogie frame concentrated on the center line position of the track beam, making the operation more stable.

[0009] Further defined, braking mechanisms are also installed on the left and right sides at the bottom of the bogie frame. Such a structural design further improves the braking effect.

[0010] The beneficial effects of the present utility model are as follows: The present utility model aims to solve the problems of high wheel replacement frequency, high maintenance cost, and high operation cost caused by uneven wear of the running wheels, guiding wheels, and stabilizing wheels during the operation of the existing overhead tour vehicle bogie. The differential gearbox changes the original single-arm structure into a double-arm structure, greatly reducing the uneven wear of the running wheels.

[0018] As Figures 1-3As shown in the figure, a differential type double - shaft power bogie for an aerial sightseeing vehicle of the present utility model. Mounting seats 2 are installed on the front and rear sides of the bottom of the bogie frame 1. A differential gearbox 3 is installed at the bottom of the mounting seat 2. A traction motor 4 is installed on the outer side of the differential gearbox 3. The power output end of the traction motor 4 is connected to the differential gearbox 3. The power output ends on both sides of the differential gearbox 3 are connected with running wheels 5. Cross - shaped auxiliary frames 6 are installed on the left and right sides of the bogie frame 1. Guide wheels 7 are installed on the front and rear sides of the auxiliary frame 6. A stabilizer wheel 8 is installed at the bottom of the auxiliary frame 6.

[0019] Preferably, a brake 9 is installed on the outer side of the running wheel 5. Such a structural design can directly brake the running wheel 5, improving the braking effect. In fact, other braking structural shapes of the running wheel 5 can also be considered according to specific situations.

[0020] Preferably, a lifting ring 10 is installed on the top outer side of the traction motor 4. The lifting ring 10 is connected with a suspension rope 11. The other side of the suspension rope 11 is connected with a suspension seat 12. The suspension seat 12 is installed on the bogie frame 1. Such a structural design can play a role in pulling up the traction motor 4 upward, preventing the traction motor 4 from tilting after long - term use. In fact, other auxiliary installation structural shapes of the traction motor 4 can also be considered according to specific situations.

[0021] Preferably, the differential gearbox 3 is arranged at the middle position of the bogie frame 1, and the traction motor 4 is installed in the middle of the differential gearbox 3. Such a structural design makes the center of gravity of the entire bogie frame 1 concentrated on the center line position of the track beam, making the operation more stable. In fact, other centering installation structural shapes of the differential gearbox 3 and the traction motor 4 can also be considered according to specific situations.

[0022] Preferably, braking mechanisms 13 are also installed on the left and right sides of the bottom of the bogie frame 1. Such a structural design further improves the braking effect. In fact, other braking structural shapes of the bogie frame 1 can also be considered according to specific situations.

[0023] In this embodiment, the application scenario of the present utility model is: the field of aerial sightseeing vehicles of special equipment large - scale amusement facilities.

[0024] During use, by starting the traction motor 4, the traction motor 4 drives the differential gearbox 3, and the differential gearbox 3 drives the running wheels 5 to rotate, so that the running wheels 5 move on the track beam 14. When moving, the bogie frame 1 synchronously drives the auxiliary frames 6 on both sides, and the auxiliary frames 6 drive the guide wheels 7 and the stabilizer wheels 8 to move on both sides of the track beam 14, ensuring the smooth movement of the running wheels 5.

[0025] Among them, the differential gearbox 3 is installed at the lower part of the bogie frame 1 through the mounting seat 2. The running wheels 5 are arranged on both sides of the differential gearbox 3 to form a double-arm support. Such a structural form greatly reduces the eccentric wear of the running wheels 5. At the same time, a differential is provided inside the differential gearbox 3, which reduces the horizontal rotational friction of the running wheels 5 when the vehicle passes through a curve, prolongs the service life of the running wheels 5, reduces the replacement frequency, and saves the maintenance cost and operation cost. The traction motor 4 is installed in the middle of the differential gearbox 3, so that the center of gravity of the entire bogie frame 1 is concentrated at the center line position of the track beam 14, and thus the operation is more stable. A brake 9 is provided outside the running wheel 5 to directly brake the running wheel 5, and such a braking effect is better. Since the center of gravity of the entire bogie frame 1 is evenly distributed and the center of gravity point is located at the center line position of the track beam 14, this also prevents the guide wheels 7 and the stabilizer wheels 8 from being eccentrically worn, further prolongs the service life, reduces the replacement frequency, and saves the maintenance cost and operation cost.
