The invention discloses a novel hybrid power transmission, which comprises a shell, a power source, a single planet row mechanism, a differential mechanism, a variable speed transmission mechanism, abrake device and a first synchronizer, wherein the single planet row mechanism is constructed to have a differential speed or variable speed function and can transmit engine power and/or first motor power to the variable speed transmission mechanism after being subjected to differential speed or variable speed; the variable speed transmission mechanism is constructed to have a variable-speed function and can transmit power of the single planet row mechanism to the differential mechanism at a preset speed ratio; and the brake device configured to have a function of transmitting power in at least one direction. The novel hybrid power transmission has the advantages of low manufacturing cost, small occupied space and high reliability, can fully meet power requirements of a hybrid power vehicle under different driving working conditions, and can flexibly adjust the working point of the engine to ensure that the engine works in a high-efficiency working interval, so that the high efficiencyof the whole hybrid power system is effectively guaranteed.
