Abstract
The invention discloses a bogie. As a T-beam and a straight beam are connected through a rotating device, when the wheel load on a front shaft and the wheel load on a rear shaft of the bogie are inconsistent and additional torque is generated, the T-beam and the straight beam rotate correspondingly until balance is achieved, and then the wheel loads can be evenly distributed automatically. Meanwhile, the upper end of a center pin is arranged in a center pin base, and the lower end of the center pin is in flexible connection with a draft sill, so that through the structural design, low-position traction is achieved, the height of towing points can be decreased, and transfer of the front wheel load and the rear wheel load caused by traction when the bogie runs is reduced. Through a rotatable bogie body and a low-position traction device, the adhesion utilization rate can be improved, abrasion to wheels is reduced and even, the traction performance of a car can be brought into play, the running performance of the car is improved, and abrasion to wheel-rails is reduced.

Preferably, above-mentioned center pin and described draw beam are realized and being flexibly connected by springing.
Preferably, above-mentioned springing is complex spring.
Preferably, above-mentioned slewing arrangement is bearing arrangement.
Preferably, above-mentioned center pin is fitted in the key seat of described center.
Preferably, above-mentioned crossbeam is arranged on the middle part of described longeron side, and the middle part of described crossbeam and described straight beam aligns.
Bogie truck provided by the invention, comprise bogie truck body and draw gear, described bogie truck body comprises T-girder, straight beam and slewing arrangement, wherein, described T-girder comprises longitudinal and cross beam, described crossbeam is fixed on the side of described longeron, described crossbeam is connected by described slewing arrangement with described straight beam, described draw gear comprises center key seat, center pin, draw beam and drawing pull bar, described center key seat is fixedly connected with described car body, the upper end of described center pin is arranged in the key seat of described center and its lower end and described draw beam flexibly connect, described draw beam is connected by described drawing pull bar with described bogie truck body.
Wherein, because T-girder is connected by slewing arrangement with straight beam, while producing additional torque when the wheel load on the diaxon of bogie truck front and back is inconsistent so, there is corresponding rotation until reach balance in T-girder and straight beam, and then makes wheel load automatically reach and be uniformly distributed.Simultaneously, the upper end of center pin is arranged in the key seat of described center and its lower end and described draw beam flexibly connect, by this structure design, realized low level traction, can reduce drawbar height, the front and back Wheel Weight Transfer that while moving to reduce bogie truck, tractive force causes, by adopting the draw gear of rotatable bogie truck body and low level, can improve utilization of adhesion, reduce wheel wear and make it uniformization, be conducive to the performance of vehicle tractive property, be also conducive to improve vehicle operating performance, reduce wheel-rail wear simultaneously.
