Abstract

The invention discloses an automobile reduction gearbox and an automobile, the automobile reduction gearbox comprises a shell and a gear set arranged in the shell, the shell comprises a mounting wall used for bearing the gear set, the gear set comprises an output gear, the mounting wall is provided with a first bearing chamber correspondingly used for bearing the output gear, and the first bearing chamber is provided with a second bearing chamber correspondingly used for bearing the output gear. The mounting wall is further provided with an oil collecting groove internally provided with a first blocking rib, the oil collecting groove extends downwards and is communicated with the first bearing chamber, the first blocking rib can block oil thrown out by the output gear, and the blocked oil can flow into the first bearing chamber along the oil collecting groove. According to the oil guide device, thrown-out oil liquid can be drained, the oil guide efficiency and the oil guide amount are improved, and therefore the lubricating effect is enhanced.

Description

Technical field [0001] The present invention relates to the field of electric drive systems, particularly to a kind of automotive gearbox and a car. Background [0002] As the mainstream technical solution of new energy vehicles, electric vehicles are currently concerned about major car companies and users. At present, the three-in-one electric drive assembly used in electric vehicles, especially pure electric vehicles, is the mainstream power system at present and in the future, and the gearbox is still an important part of the power transmission. The gearbox can affect the efficiency of the vehicle drive system, which in turn affects the vehicle's demand for power battery and motor power matching. Compared with traditional cars, the single-gear deceleration device of pure electric vehicles faces ultra-high input speed, and the mainstream is currently 12000~16000rpm, which brings lubrication cooling, transmission efficiency, and NVH related problems. Based on the weight and cos...
