Abstract

The invention relates to a non-complete load power frame for improving traction force of a rack rail train, which comprises a framework, wheels, wheel axle boxes, a gear box, a driving gear, a traction motor, a rack rail braking device, a secondary suspension and a tread braking device, the framework is connected to a train body chassis through a longitudinal traction device, and the traction force transmitted by the longitudinal traction device is arranged along a rail direction; the secondary suspension comprises a lifting device and a secondary spring, the lifting device is used for being connected to a chassis of the vehicle body, the secondary spring is connected to the framework and located below the lifting device, the movable end of the lifting device can descend to abut against the secondary spring, and the power frame is used for being arranged between an adhesive bogie and a rack rail bogie of the vehicle body. When the vehicle adheres to a road section, the movable end of the lifting device ascends and retracts, and the power frame does not bear the vertical load of the vehicle body; in the rack rail section, the movable end of the lifting device descends to abut against the secondary spring, the power frame bears part of the vertical load of the vehicle body, and the power frame provides traction force for the vehicle body.

本发明关于一种提升齿轨列车牵引力的非完全荷载动力架，包括构架、车轮、车轮轴箱、齿轮箱、驱动齿轮、牵引电机、齿轨制动装置、二系悬挂和踏面制动装置，构架通过纵向牵引装置连接于车体底架，纵向牵引装置传递的牵引力沿轨道方向设置，二系悬挂包括升降装置和二系弹簧，升降装置用于连接于车体底架，二系弹簧连接于构架，二系弹簧位于升降装置下方，升降装置的活动端能够下降抵接于二系弹簧，动力架用于设置于车体的粘着转向架和齿轨转向架之间。本发明在粘着路段时，升降装置的活动端上升收起，动力架不承担车体的垂向载荷；在齿轨路段时，升降装置的活动端下降抵接于二系弹簧，动力架承担部分车体的垂向载荷，动力架为车体提供牵引力。
