The invention belongs to the technical field of rail transit, and particularly relates to a vehicle frame. The vehicle frame comprises a basic frame, the basic frame comprises a main longitudinal beam, a plurality of center pin holes are formed in the main longitudinal beam at intervals, the center pin holes and center pins are arranged in a one-to-one correspondence mode, the lower ends of the center pins movably penetrate through the corresponding center pin holes, the lower ends of the center pins are connected with a swing bolster, and the swing bolster is located below the basic frame. And a plurality of elastic pieces are arranged between the swing bolster and the main longitudinal beam. The stress level of the frame can be improved, and the fatigue life of the frame is prolonged.

    本发明属于轨道交通技术领域,尤其涉及一种车架。该车架包括基础框架,该基础框架包括主纵梁,主纵梁上间隔设置有多个中心销孔,中心销孔和中心销一一对应设置,中心销的下端活动穿过对应的中心销孔,中心销的下端同摇枕连接,摇枕位于基础框架的下方,摇枕和主纵梁之间设置有多个弹性件。本发明可改善车架的应力水平,提高车架的疲劳寿命。
