Description

Technical Field

[0001] The utility model belongs to the technical field of bogies, and particularly relates to a vehicle integrated bogie capable of adapting to a small curve radius. Background Technique

[0002] For the existing car running system of tourist rail transit sightseeing trains, a mode of one car with two non-powered bogies is adopted. Generally, the vehicle bodies with this layout form are relatively wide, have high requirements for the line clearance and turning radius, and have poor adaptability to projects with complex terrain conditions. Content of the Utility Model

[0003] Aiming at the problems raised in the above background technique, the purpose of the utility model is to provide a vehicle integrated bogie capable of adapting to a small curve radius.

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

[0005] A vehicle integrated bogie capable of adapting to a small curve radius, including a chassis. A motor mounting frame is installed at the bottom of the chassis. The motor mounting frame is hingedly installed with a motor. The output end of the motor is connected with a gear steering box. The gear steering box has two output ends. The two output ends of the gear steering box rotate synchronously, coaxially and in the same direction. Rolling wheels are installed at the two output ends of the gear steering box. Two follower wheels are installed on the lower side of the chassis. The positions of the two follower wheels correspond to the two rolling wheels. Shock-absorbing support frames are installed between the rolling wheels, the follower wheels and the chassis.

[0006] Further defined, retaining rings are integrally connected to the adjacent sides of the rolling wheels and the follower wheels. Such a design is conducive to forming a fit with the track and has a low derailment probability.

[0007] Further defined, traction buckles are integrally connected to the front and rear ends of the chassis. Such a design is conducive to forming a traction connection.

[0008] Further defined, the chassis includes at least four cross beams and six vertical beams. Such a design ensures the structural strength of the chassis.

[0009] Further defined, a rotating rod is fixedly connected between the two follower wheels. The rotating rod is installed on the chassis through a bearing. Such a design increases the linkage and the overall structural strength.

[0010] Advantages of adopting the utility model:

[0011] The utility model solves the problem that the vehicle steering system cannot adapt to the line conditions due to the too small line clearance and curve radius of the track at the project site;

[0012] With the structural design of the present utility model, the bogie is self-powered, enabling each bogie to rotate freely relative to the carriage. When the carriage turns, the two bogies rotate simultaneously to drive the carriage to complete the turn, and the use effect is good;

[0013] The present utility model directly connects a single bogie to the carriage chassis, and converts the rotation of a single bogie of a tourist rail transit sightseeing train into the rotation of the entire vehicle body. In this way, not only is the adaptability to the curve radius of the line stronger, but also the size of the carriage can be greatly reduced, while meeting the clearance and curve requirements under complex terrain conditions. Moreover, compared with the carriage adopting the traditional steering system, the carriage adopting the integrated bogie of the vehicle body can flexibly increase or decrease the carriages to meet the passenger-carrying requirements at different times.

[0020] In order to enable those skilled in the art to better understand the present utility model, the technical solutions of the present utility model will be further described below in conjunction with the drawings and embodiments.

[0021] As Figure 1 、 Figure 2 、 Figure 3As shown in the figure, an integrated bogie for a car body that can adapt to a small curve radius of the present utility model includes a chassis 1. A motor mounting bracket 2 is installed at the bottom of the chassis 1. The motor mounting bracket 2 is hingedly installed with a motor 3. The output end of the motor 3 is connected to a gear steering box 4. The gear steering box 4 has two output ends, and the two output ends of the gear steering box 4 rotate synchronously, coaxially and in the same direction. Rolling wheels 5 are installed at both output ends of the gear steering box 4. Two follower wheels 6 are installed on the lower side of the chassis 1. The positions of the two follower wheels 6 correspond to the two rolling wheels 5. Shock-absorbing support frames 7 are installed between the rolling wheels 5 and the follower wheels 6 and the chassis 1.

[0022] In this embodiment, when using an integrated bogie for a car body that can adapt to a small curve radius, the motor mounting bracket 2 is installed on the chassis 1, and then the motor 3 is installed on the motor mounting bracket 2. The synchronous drive of the output end of the motor 2 and the rolling wheel 5 is completed through the gear steering box 4. Then, the follower wheels 6 are installed, and it can be started to use. During the moving process, the integrated bogie itself has the power brought by the motor 3. Therefore, a single bogie can be directly connected to the carriage chassis, and the rotation of a single bogie of the tourist rail transit sightseeing train is integrally converted into the rotation of the entire car body. In this way, not only the adaptability to the curve radius of the line is stronger, but also the size of the carriage can be greatly reduced, while meeting the clearance and curve requirements under complex terrain conditions. And compared with the carriage using the traditional steering system, the carriage using the integrated bogie of the car body can flexibly increase or decrease the carriages to meet the passenger-carrying requirements in different periods.

[0023] Preferably, retaining rings 8 are integrally connected to the adjacent sides of the rolling wheels 5 and the follower wheels 6. Such a design is conducive to forming a fit with the track, and the derailment probability is low. In fact, the specifications and dimensions of the retaining rings 8 can also be considered according to specific situations.

[0024] Preferably, traction buckles 9 are integrally connected to the front and rear ends of the chassis 1. Such a design is conducive to forming a traction connection. In fact, the specifications and shapes of the traction buckles 9 can also be considered according to specific situations.

[0025] Preferably, the chassis 1 includes at least four cross beams and six vertical beams. Such a design ensures the structural strength of the chassis 1. In fact, the structure of the chassis 1 can also be considered according to specific situations.

[0026] Preferably, a rotating rod 10 is fixedly connected between the two follower wheels 6, and the rotating rod 10 is installed on the chassis 1 through bearings. Such a design increases the linkage and the overall structural strength. In fact, the installation method of the rotating rod 10 can also be considered according to specific situations.
