The invention belongs to the technical field of commercial hybrid power vehicles and relates to a multi-gear transmission case, in particular to a parallel type hybrid power multi-gear transmission case for power gear-shifting of a commercial vehicle. According to the technical scheme, the power of an engine is input to an engine input shaft after passing through a clutch; a motor module comprises an electromotor and a transmission gear, and the motor power is output through the transmission gear and an electromotor input shaft; a main box module of the transmission case is composed of a multi-degree of freedom fixed-axle gear mechanism, can be coupled with the power of the engine and a motor, and can realize the gears of five matched engines and the gears of two matched motors; an auxiliary box module of the transmission case can realize a high gear and a low gear; the auxiliary box module of the transmission case collaborates with the main box input module of the transmission case, so that the gears of ten matched engines and the gears of four matched motors can be realized. The parallel type hybrid power multi-gear transmission case has the characteristics that the multi-degree of freedom gear mechanism is adopted to couple the power of the engine and the motor and realizes the hybrid power and power gear-shifting functions.
