[0021] The front end beam 2 is a sinking structure, and the height of the upper plane is lower than the lowest point of the coupler buffer, so the bogie can move forward toward the coupler as a whole.

[0022] A traction frame 6 is provided at the bottom of the traction beam 3, and mounting holes for mounting elastic blocks are provided on all four sides of the traction frame 6. A corresponding hollow structure is provided above the traction frame 6 for passing the traction pin. The hollow structure is provided on the traction beam 3. In order to increase the overall rigidity of the traction beam 3, a rectangular annular rib plate is arranged between the upper cover plate of the traction beam 3 and the traction frame 6, and oblique rib plates are arranged at the four corners of the space formed by the rib plate and the upper cover plate.

[0023] In some embodiments, the width of the connection between the traction beam 3 and the side beam 1 is smaller than the width of the traction frame 6. The control is used to arrange the driving device and reduce the wheelbase.

[0024] The present invention is applied to a three-axle bogie with a center pin traction mode, wherein the traction beam 3 adopts a sunken curved beam structure, and has the characteristics of low traction point, low frame height, short frame length, small frame cross section, light weight, and good versatility of mounting seat structure.

[0025] In some embodiments, the front end beam 2 is a box-type structure with a plurality of ribs arranged inside, so as to increase the overall rigidity of the end of the present invention, and different mounting seats can be arranged in various directions of the front end beam 2.

[0026] It should be noted that the front beam 2 has four plane surfaces, top and bottom, front and back. The cross section of the front beam 2 can be adjusted appropriately, and the height from the lower cover plate of the side beam 1 can also be increased or decreased.

[0027] In some embodiments, a mounting seat integrating a stone sweeper and a sand spreading bracket is arranged on the lower plane of the front end beam 2 .

[0028] like Figure 1 As shown, in some embodiments, the traction beam 3 and the cross beam 4 are both provided with a motor anti-detachment seat 7 and a motor mounting seat 8; the motor anti-detachment seat 7 and the motor mounting seat 8 are both arranged on the same side of the traction beam 3 and the cross beam 4; the motor anti-detachment seat 7 is welded by two seat plates and a rib plate, and in order to ensure the coaxiality of the through hole, the through hole is processed after welding and welded to the side of the traction beam 3 and the cross beam 4 as a whole.

[0029] In some embodiments, a motor anti-drop seat 7 and a motor mounting seat 8 are also provided on the rear end beam 5 .

[0030] like Figure 1 As shown, in some embodiments, the crossbeam 4 is made of a thick plate of a certain thickness. By removing a certain amount of material from the inner side of the traction beam 3 and the crossbeam 4, the space requirement for the installation of the two middle hangers is guaranteed, while also ensuring the plate thickness at the welding position with the crossbeam.

[0031] The side beam 1 is provided with a brake cylinder mounting seat and a spring cylinder mounting seat on the outside; a brake adjuster is provided on the inside of the side beam 1. Since the brake cylinder and the adjuster are connected by a cross bar, the cross bar has a certain movement space, so a long strip hole is opened on the side beam 1 for passing the cross bar.

[0032] It should be noted that the rotation axis of the crossbar is under the side beam cover plate, and a circular hole is opened in the side bearing mounting plate and the upper cover plate of the side beam 1 at the corresponding position to arrange the round pin used for rotating the crossbar.

[0033] In some embodiments, a brake seat is also provided on the side beam 1. The brake seat is divided into two parts. The part for installing the crossbar rotation pin is composed of three plates, which are integrally welded to the inner side of the side beam 1. The side plane that does not contact the side beam 1 is integrally processed and used to install the other part. The other part of the brake seat is welded to the processed surface of the first part, the side surface of the cross beam 4, and the lower plane of the cross beam 4. The two large circular holes on one side of the brake seat are used to fix the brake shoe and adjuster of the rod system brake, and the group of small circular holes on the other side are used to fix the brake cylinder of the unit brake.

[0034] In some embodiments, two adjustment blocks are welded on the brake seat main board to meet the space requirements for unit brake installation.

[0035] In some embodiments, a spring cylinder seat is provided on the outer side of the side beam 1. In order to avoid the shock absorber, the spring cylinder seat needs to be raised. A part of the spring cylinder seat is used for the overall lifting of the axle box, and a separate lifting seat is arranged on the other side.

[0036] In some embodiments, a transverse stop seat is arranged on the side beam 1, and the transverse stop seat is welded to the upper cover plate and the inner vertical plate of the side beam 1.

[0037] In some embodiments, a transverse shock absorber seat is arranged on the side beam 1, and the transverse shock absorber seat is welded together with the side beam upper cover plate and the inner side vertical plate.

[0038] In some embodiments, anti-collision seats are arranged at two end surfaces of the side beam 1, and a lifting seat is arranged on the upper plane of the side beam 1.

[0039] In some embodiments, a tie rod seat, a spring mounting seat and a side bearing mounting seat are welded on the lower plane of the side beam 1.

[0040] like Figure 2 As shown, in some embodiments, the cross-section of the side beam 1 is equal in the middle section, and gradually decreases in the front and rear sections.

[0041] Two through holes are arranged at the front end of the lower cover plate of the side beam 1, and a through hole is arranged at the side of the sand box seat for installing the wheel rim lubrication bracket.

[0042] The side beam 1 and the traction beam 3 are butt-welded in an interlaced manner to ensure welding quality.

[0043] The docking position of the traction frame 6 and the lower cover plate of the traction beam 3 adopts a turning type to ensure the overall strength and height of the traction frame and facilitate the processing of the mounting holes on both sides. The shape of the traction frame 6 is relatively regular and can be formed by thick plate processing.

[0044] The front end beam of the present invention is a sunken structure, and the height of the upper plane is lower than the lowest point of the coupler buffer, so that the bogie can move forward in the direction of the coupler as a whole. A certain number of ribs are arranged inside the front end beam to increase the overall rigidity of the frame end, and different mounting seats can be arranged in various directions of the front end beam. Motor mounting seats, anti-slip seats, brake seats, etc. are installed on the sides of the crossbeam and the rear end beam, and ribs are arranged at corresponding positions inside; the traction beam is a sunken curved beam, which reduces the height of the traction point of the whole vehicle. The arc structure at the connection with the side beam provides space for the drive device and reduces the wheelbase of the bogie. The traction beam and the side beam are welded by staggered butt welding to ensure the welding quality. The docking position between the traction frame and the lower cover plate of the traction beam adopts a turning type to ensure the overall strength and height of the traction frame, and is also convenient for the processing of the mounting holes on both sides. The shape of the traction frame is relatively regular and can be formed by thick plate processing; the side beam is a box-shaped welded structure with a high middle and low ends, and is arranged with a spring mounting seat, a side bearing mounting seat, a shock absorber seat, a stop seat, a brake seat, etc. The side beam has three long holes in the horizontal direction for inserting the brake cross bar, and three round holes in the vertical direction for installing the transmission round pin. The brake seat has two groups of round holes, one group for installing the rod system brake, and one group for installing the unit brake. The two braking methods are optional to meet different needs. In order to meet the different size requirements of the two brake installations, two mounting blocks are added to the mounting plate to adjust the space for the unit brake installation. The lateral stop seat and the lateral shock absorber seat are welded to the vertical plate and the upper cover plate of the side beam, which increases the local strength of the two seats.
