The embodiment of the invention provides a motor car body, a motor car and a motor train unit, the motor car body comprises a chassis, a cab, a car coupler energy absorption device and an anti-creeping energy absorption device, the cab is arranged at the upper part of the front end of the chassis, the car coupler energy absorption device is arranged at the front end part of the chassis, and the anti-creeping energy absorption device is divided into a first anti-creeping energy absorption device and a second anti-creeping energy absorption device; the first anti-creeping energy-absorbing device is arranged at the front end part of the chassis, and the second anti-creeping energy-absorbing device is at least partially arranged at the front end part of the cab; the triggering force value of the second anti-creeping energy absorption device is smaller than that of the first anti-creeping energy absorption device. According to the bullet train body provided by the embodiment of the invention, the first anti-creeping energy absorption device and the second anti-creeping energy absorption device which have unequal trigger force values are arranged on the chassis and/or the cab, so that the overall absorption capacity value of the anti-creeping energy absorption device arranged at the head of the bullet train body is larger, and the longitudinal load borne by the head of the bullet train body is more balanced; therefore, the head of the bullet train body can bear the longitudinal load during higher-speed collision.

    本申请实施例提供一种动车车体、动车及动车组,动车车体包括底架、司机室、车钩吸能装置以及防爬吸能装置,司机室设置在底架的前端上部,车钩吸能装置设置在底架的前端部,防爬吸能装置分为第一防爬吸能装置和第二防爬吸能装置;第一防爬吸能装置设置在底架的前端部,第二防爬吸能装置至少部分设置在司机室的前端部;第二防爬吸能装置的触发力值小于第一防爬吸能装置的触发力值。本申请实施例提供的动车车体,通过不等触发力值的第一防爬吸能装置和第二防爬吸能装置设置在底架和/或司机室上,使动车车体的头部设置的防爬吸能装置整体吸能力值更大,动车车体的头部受到的纵向载荷更加平衡,从而使动车车体头部能够承受更大速度碰撞时的纵向载荷。
