The embodiment of the invention provides a three-point rigid frame suspension direct driving type driving device, and relates to the technical field of rail traffic vehicles. The three-point rigid frame suspension direct driving type driving device comprises a suspension frame, a wheel set, a driving motor, a first transmission mechanism, a second transmission mechanism and a transmission shaft, wherein the driving motor is suspended on the suspension frame; the transmission shaft is inserted into a mover of the driving motor; the transmission shaft is arranged on an axle of the wheel set in asleeving way; an output shaft of the driving motor is connected with one end of the transmission shaft through the first transmission mechanism so as to transmit power to the transmission shaft; theother end of the transmission shaft is connected with axle of the wheel set through the second transmission mechanism; and the driving motor is connected with the suspension frame through a three-point rigid suspension mechanism. Compared with a traditional motor arrangement mode, the three-point rigid frame suspension direct driving type driving device provided by the embodiment of the inventionhas the advantages that the occupied space is small; the mass of the part from the wheel set to the first-series suspension device is favorably reduced; and the running speed of a motor train unit iseffectively accelerated.

    本发明实施例提供一种三点刚性架悬直驱式驱动装置,涉及轨道交通车辆技术领域。三点刚性架悬直驱式驱动装置包括悬挂架、轮对、驱动电机、第一传动机构、第二传动机构及传动轴,驱动电机悬挂于悬挂架,传动轴插设于驱动电机的动子内,传动轴套设于轮对的车轴,驱动电机的输出轴通过第一传动机构与传动轴的一端相连以便将动力传递至传动轴,传动轴的另一端通过第二传动机构与轮对的车轴相连,驱动电机通过三点式刚性悬挂机构与悬挂架相连。本发明实施例提供的三点刚性架悬直驱式驱动装置,相比于传统电机布设方式,空间占用小,有助于减轻轮对至一系悬挂装置以下部分的质量,有效提升动车组的运行速度。
