Title
(EN) Railway vehicle body chassis structure
(ZH) 一种轨道车辆车体底架结构
Abstract
(EN)
The invention discloses a railway vehicle body chassis structure. The railway vehicle body chassis structure soles the problems that the giant torque force is caused due to the fact that a front-arrangement type vehicle hook mounting hole is formed in the side face of a vertical plate of a traction beam, and no operation space exists for mounting a steering frame traction base. The railway vehicle body chassis structure comprises two chassis edge beams, a chassis end beam and a sleeper beam arranged between the two chassis edge beams, a traction beam, a vehicle hook mounting sectional material and a traction guide beam are arranged between the sleeper beam and the chassis end beam, the traction beam is fixed between the sleeper beam and the vehicle hook mounting sectional material, and the traction guide beam is fixed between the vehicle hook mounting sectional material and the chassis end beam. Traction wing plates are fixedly arranged on the two sides of the vehicle hook mounting sectional material, the traction wing plates are fixedly connected with the chassis edge beams on the corresponding sides, and a jumper box is arranged between the traction wing plates and the traction guide beam. The problems are completely solved by optimizing the structures of vehicle hook mounting sectional material, the traction beam and other components, and the high-intensity performance that a vehicle body can bear 1000 kN of compression loads is kept.
