In conjunction with the structure of the bogie frame, it is known that a change in the direction of transmission occurs between the primary gearbox 6 and the secondary gearbox 7. The power transmission direction among the primary gearboxes 6 is in the lateral direction, and the power transmission direction of the secondary gearboxes 7 is in the longitudinal direction.
In this kind of "king" style of calligraphy bogie frame, its bearing capacity is stronger, and gear box and motor box 3 need not additionally to occupy the space under the car.
According to the utility model discloses a one of them embodiment, the distance of box crossbeam apart from first end roof beam 4 equals with the distance of box crossbeam apart from second end roof beam 5, and then has guaranteed the structural symmetry of the bogie frame of "king" style of calligraphy.
According to the utility model discloses a another embodiment, the box roof beam is the vertical ridge roof beam of box, include along vertical gear box, motor box 3 and the gear box that sets gradually. In this case, the bogie frame is in the shape of an i-like shape. Compared with a king-shaped bogie frame, the bogie frame is simple in structure and light in weight, and the bearing capacity of the bogie frame is not as good as that of the king-shaped bogie frame.
According to the utility model discloses a one of them embodiment, traction motor body 2 adopts water-cooling permanent-magnet machine to improve energy utilization.
The bogie frame for the railway vehicle has the advantages of compact structure and small occupied space, and can reduce the height of the vertical section of the railway vehicle and reduce the overall weight of the railway vehicle. The rail vehicle with the bogie frame has uniform load during operation, reduces the abrasion probability of the running wheels during operation, prolongs the service life of the running wheels, improves the operation safety, reduces the later maintenance cost and reduces the operation cost.
The rail vehicle in the above "rail vehicle bogie motor and rail vehicle bogie frame" may be either a single rail vehicle or a double rail vehicle.
Taking a double-shaft straddle type monorail vehicle as an example, the operation stability and the stability are good, the riding is comfortable, and the passenger capacity is large, but because the floor structure and the section of the track beam 10 are as high as 1.5 meters, the structure of a double-shaft straddle type monorail traffic system is expected to be optimized by customers, so that the floor height of the straddle type monorail vehicle is reduced, the escape and evacuation of the passengers are facilitated, and the operation safety is improved.
When the double-shaft straddle type monorail vehicle adopts the rail vehicle bogie motor and the rail vehicle bogie framework, the height of the section of the rail beam is greatly reduced, specifically, the height of the section of the rail beam 10 can be reduced by about 600mm, and the escape and evacuation level of passengers is improved under the condition that the height of the vehicle floor is not changed. In addition, under the condition of combining and optimizing the vehicle body structure, the height of the passing section of the vehicle track can be reduced to about 700mm, so that the height of the section of the tunnel can be reduced, and the construction cost is saved.
The above embodiments are merely illustrative, and not restrictive, of the present invention. Although the present invention has been described in detail with reference to the embodiments, it should be understood by those skilled in the art that various combinations, modifications or equivalent substitutions may be made to the technical solution of the present invention without departing from the spirit and scope of the technical solution of the present invention, and all of the technical solutions should be covered by the scope of the claims of the present invention.
