A gearbox (200) comprises a box body (510) with an inner cavity (240), a gear set (210) and an oil feeder (100), the gear set (210) and the oil feeder (100) are contained in the box body (510), an oil storage pool (243) for bearing lubricating oil is arranged at the bottom of the inner cavity (240), the oil feeder (100) comprises a sealing bin (110) and an oil collecting groove (120) which are fixedly connected, the sealing bin (110) is provided with an oil inlet (111) and an oil spraying pipe (112), the lubricating oil in the oil storage pool (243) is fed from the oil inlet (111), and the oil spraying pipe (112) is communicated with the oil collecting groove (120). The oil spraying pipe (112) is arranged on the gear set (210) and sprays lubricating oil towards a to-be-lubricated part of the gear set (210) through the oil spraying pipe (112), the oil collecting groove (120) is provided with an upper opening (123) and is used for receiving the lubricating oil which is stirred and fed when the gear set (210) rotates, and the oil collecting groove (120) is further provided with an oil conveying groove (124) corresponding to the oil spraying pipe (112) and is used for lubricating the same to-be-lubricated part with the corresponding oil spraying pipe (112). The oil feeder (100) achieves active lubrication through the sealing bin (110) and achieves passive lubrication through the oil collecting groove (120), it is guaranteed that the gearbox (200) works reliably through cooperation of the two modes, the positions of the oil spraying pipe (112) and the oil conveying groove (124) are adjustable, and portability is high. The invention further relates to an automobile power assembly (500) comprising the gearbox (200) and an automobile.

    一种变速箱(200),包括具有内腔(240)的箱体(510),以及收容于箱体(510)内的齿轮组(210)和供油器(100),内腔(240)底部设有承载润滑油的储油池(243),供油器(100)包括固定连接的密封仓(110)和集油槽(120),密封仓(110)设有进油口(111)以及喷油管(112),储油池(243)中的润滑油从进油口(111)送入,并经喷油管(112)朝向齿轮组(210)的待润滑部位喷射润滑油,集油槽(120)具有上部开口(123),用于在齿轮组(210)转动时接收搅动送入的润滑油,集油槽(120)还对应于喷油管(112)设有输油槽(124),用于与对应的喷油管(112)润滑同一待润滑部位。供油器(100)通过密封仓(110)实现主动润滑,并通过集油槽(120)实现被动润滑,两种方式配合保证变速箱(200)工作可靠,且喷油管(112)和输油槽(124)的位置可调,移植性强。还涉及包括变速箱(200)的汽车动力总成(500),以及一种汽车。
