Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] See also Figure 1-7 The present invention provides a technical solution: a bogie traction device, comprising a frame 1 and a housing 2 on the frame 1, and further comprising:

[0052] A power unit 3 is provided on the frame 1 and is used to drive the frame 1 to move on the track;

[0053] The auxiliary unit 4 is disposed on the frame 1 and is used to keep the frame 1 stable when the power unit 3 drives the frame 1 to move.

[0054] Wherein, the power unit 3 comprises:

[0055] Two sets of rollers 31 are provided on the frame 1 and are used for setting the frame 1 on the track;

[0056] A speed reducer 32 is arranged on the axle of the roller 31;

[0057] A motor 33 is disposed on the frame 1, and the motor 33 is connected to the reducer 32 via a coupling 35, so as to drive the wheel shaft to rotate via the reducer 32;

[0058] The anti-vibration device 34 is arranged between the axle of each group of the rollers 31 and the frame 1, and is used to prevent vibration when the frame 1 is traveling, so as to make the travel more stable.

[0059] In addition, the anti-vibration device 34 includes:

[0060] A plurality of connecting shafts 341 are coaxially arranged outside the roller 31 and extend to the outside of the frame 1;

[0061] A connecting plate 342, one end of which is rotatably arranged with the lower end of the frame 1, and the other end of which is movably connected with the outer section of the frame 1 through an elastic connecting member 36. The connecting plate 342 is provided with a connecting slot into which the connecting shaft 341 is rotatably inserted. One end of the elastic connecting member 36 is rotatably connected with the frame 1 through a sleeve ring, and the other end of the elastic connecting member 36 is rotatably arranged with the connecting plate 342 through a sleeve ring.

[0062] The outer shell of the coupling 35 is rotatably provided with a connecting bar 343 , and the connecting bar 343 is rotatably provided away from one end of the outer shell of the coupling 35 and the frame 1 .

[0063] At the same time, the elastic connecting member 36 includes:

[0064] The first slide 361 is rotatably connected to the frame 1 via a collar;

[0065] A first sliding rod 362, one end of which is limitedly slidably disposed in the first sliding cylinder 361, and the other end of which is rotatably disposed through a sleeve ring and the connecting plate 342;

[0066] A first spring 363 is disposed in the first slide cylinder 361, one end of which is connected to the end of the first slide cylinder 361, and the other end of which is connected to the end of the first slide rod 362;

[0067] The frame 1 drives the coupling 35 to rotate through the motor 33 in the power unit 3, which drives the reducer 32 to rotate, so that the wheel axle on the roller 31 rotates, thereby causing the roller 31 to move on the slide rail. During the movement, if vibration occurs due to external conditions, the reducer 32 connected to the roller 31 is rotatably set on the frame 1, and the roller 31 is rotatably set with the frame 1 through the connecting shaft 341, the connecting plate 342 and the elastic connecting member 36. Therefore, when the roller 31 vibrates due to external reasons, the rotation setting of the above-mentioned multiple components prevents the frame 1 from vibrating with the vibration and bumping of the roller 31, thereby keeping the frame 1 stable during the traction process.

[0068] In addition, the auxiliary unit 4 comprises:

[0069] A hollow groove 41 is hollowed out in the middle of the frame 1, and a counterweight block 42 is arranged at the position of the hollow groove 41 to increase the weight at the center of gravity of the frame 1, thereby improving the stability of the frame 1;

[0070] Two sets of elastic support components 43 are symmetrically arranged between the counterweight block 42 and the frame 1 in the traveling direction of the frame 1, so that when the frame 1 is vibrated during traveling, the force transmitted by the power unit 3 is transmitted to the elastic support components 43 through the frame 1 to be weakened, and the elastic support components 43 are used to connect the counterweight block 42 to the frame 1;

[0071] The limiting assembly 44 is disposed at the hollow position, and is used to limit the upward and downward movement position of the counterweight block 42 when the counterweight block 42 moves due to vibration.

[0072] Meanwhile, the elastic support assembly 43 includes:

[0073] A telescopic column 431, one end of which is rotatably arranged on the counterweight block 42 through a collar, and the other end of which is rotatably arranged with a connecting seat 432, wherein the connecting seat 432 is arranged on the frame 1;

[0074] Two limiting circular plates 433 are respectively disposed at both ends of the telescopic column 431 . A second spring 434 is sleeved on the telescopic column 431 between the two limiting circular plates 433 . Both ends of the second spring 434 abut against the two limiting circular plates 433 .

[0075] Wherein, the limiting component 44 includes:

[0076] Two sets of limit slide bars 441 are arranged on the counterweight block 42 in the vertical direction of the elastic support assembly 43;

[0077] Two groups of limiting slide plates 442 are respectively arranged at the limiting slide bar 441 , and the limiting slide plates 442 are provided with limiting slide grooves 443 for limiting the sliding of the limiting slide bar 441 .

[0078] In addition, two groups of adjustment components for adjusting the position of the counterweight block 42 are symmetrically arranged on the frame 1, which are used to adjust the counterweight block 42 to move in the other direction of the eccentric force when the frame 1 generates eccentric force when traveling on a curve.

[0079] The connecting seat 432 is slidably arranged on the frame 1, and the adjusting assembly includes:

[0080] A spring telescopic rod 444 is disposed on the limiting slide plate 442, and a pressure sensor is disposed inside the spring telescopic rod 444;

[0081] A power member 445, one end of which is connected to the spring telescopic rod 444, and the other end of which is disposed on the frame 1, and is used to push the counterweight block 42 to slide;

[0082] The power member 445 may be configured as an electric push rod;

[0083] When the rack 1 is traveling on the bend on the slide rail, the counterweight 42 will slide outwards due to the eccentric force, thereby compressing the spring telescopic rod 444, so that the pressure sensor will sense a value change. The changed value F 变 =F 偏心力 +F 弹簧形变量 (the amount of spring deformation of the spring telescopic rod 444 being compressed), at this time, according to F 变 The power member 445 is controlled by the value to push the counterweight 42 to the other side of the eccentric force, so as to change the center of gravity of the frame to move in the opposite direction of the eccentric force, thereby increasing the stability of the frame during the turning process;

[0084] In addition, during the process of gradually changing from turning to straight driving, the value of the pressure sensor in the spring telescopic rod 444 connected to the power member 445 that pushes the counterweight 42 to move will gradually decrease to F. 变 =F 弹簧形变量 This indicates that the frame 1 enters a straight-line driving state (eccentric force disappears). At this time, the counterweight 42 can be pushed to the initial position by the power member 445. When the power member 445 that pushes the counterweight 42 to move is working, another set of power members 445 will also pull the counterweight 42 from the other side.

[0085] Finally, the housing 2 is provided with a connection unit 5 for connecting with another towed carriage;

[0086] The connecting unit 5 comprises:

[0087] Two sets of shaft rings 51 are respectively sleeved on the housing 2 and the towed carriage;

[0088] Two groups of connecting rods 52 are connected and arranged at the ends of the two groups of shaft rings 51 close to each other;

[0089] The second slide cylinder 53 is disposed between the two groups of connecting rods 52, and the ends of the two groups of connecting rods 52 slide within the second slide cylinder 53;

[0090] Two sets of third springs 54 are sleeved on the connecting rod 52 in the second slide cylinder 53;

[0091] During driving, when the vehicle speed increases or decreases, the vehicle shell and the rear towing connected vehicle body are pulled or squeezed due to the change in vehicle speed, and the force will act on the connecting unit 5. The elastic setting can buffer the pulling or squeezing force, thereby increasing the service life of the connecting unit 5, thereby eliminating the damage to the connecting unit 5 caused by rigid connection in the prior art.
