The invention discloses a three-gear transmission for a hybrid electric vehicle. The three-gear transmission comprises a solid input shaft, a hollow input shaft, an output shaft, a differential mechanism and double clutches; the double clutches comprise the clutch I and the clutch II; a first motor and a second motor are further included, the first motor is fixedly connected with the end, away from the clutch I, of the solid input shaft, the solid input shaft is in transmission connection with the output shaft through an odd-number gear set, and the hollow input shaft is in transmission connection with the output shaft through an even-number gear set; the second motor is directly connected with the differential mechanism and transmits electric power to the differential mechanism. The three-gear transmission mainly has the advantages that the odd gears and the even gears can be alternately combined and separated under the matching of the clutch I and the clutch II, so that the power interruption phenomenon in the gear shifting process is avoided. When the two continuous gears are both odd gears or even gears, pre-combination cannot be achieved, and the pre-combination state and thecombination state are both controlled through the TCU.

    本发明揭示了一种混合动力汽车用三挡变速器,包括实心输入轴、空心输入轴、输出轴、差速器以及双离合器,双离合器包括离合器I和离合器II;还包括第一电机和第二电机,第一电机与实心输入轴的远离离合器I的一端固接,实心输入轴与输出轴之间通过奇数挡位组传动连接,空心输入轴与输出轴之间通过偶数挡位组传动连接;第二电机直连差速器并将电动力传输至差速器。本发明主要体现在:奇数挡位和偶数挡位可以在离合器I和离合器II的配合下交替结合和脱开,以避免在换挡过程中的动力中断现象。当两个连续挡位同为奇数挡位或偶数挡位时不能预结合,预结合和结合的状态均通过TCU进行控制。
