Abstract: An oil baffle of the dedicated hybrid transmission includes an oil baffle body and a connection part, the oil baffle body is an arc-shaped plate and is used for enclosing a gear position driven gear of the dedicated hybrid transmission. The connection part is connected to the oil baffle body and used for fixing the oil baffle on a transmission housing of the dedicated hybrid transmission. The oil baffle of the hybrid power transmission provided by the present application can shield and guide the oil-stirring movement of the gear teeth of the output shaft in the transmission, shorten the oil splashing path, reduce the oil bubble content, and improve the transmission efficiency of the transmission.
