Title
(EN) Traction sleeper buffer device of all-aluminum railway vehicle
(ZH) 全铝材轨道车辆的牵枕缓装置
Abstract
(EN)
The invention provides a traction sleeper buffer device of an all-aluminum railway vehicle and belongs to the field of traction sleeper buffer devices for railway vehicles. The traction sleeper bufferdevice comprises a sleeper beam, a traction beam, a drag gear installation seat and two buffer beams. A lower traction beam cover board and lower buffer beam cover boards of the traction sleeper buffer device are all made of an EN AW 5083 type aluminum plate material which is low in density, low in weight and good in bending performance, the drag gear installation seat is made from EN AW 6005A aluminum plates high in yield stress, other straight plate structures are all made of an EN AW 6082 type aluminum plate material high in yield stress, so that the overall selected materials of the traction sleeper buffer device meet the strength standard, and the welding and manufacturing processing property of the traction sleeper buffer device is the best. All lightening holes can be used as auxiliary holes at the same time in the inner cavity welding operation process, and therefore the accessibility and welding quality of an inner cavity welding joint are improved.
