The invention discloses an oil baffle plate for realizing oil surfaces with different heights, and relates to the technical field of automobile transmission. The oil baffle plate is arranged adjacent to an intermediate shaft assembly, the intermediate shaft assembly is fixedly sleeved with a first large gear, a second large gear and a control gear, the oil baffle plate is an arc-shaped shell, and the arc-shaped shell is divided into a stepped small-diameter shell and a stepped large-diameter shell. The small-diameter shell wraps the outer side of the control gear, and the large-diameter shell wraps the outer side of the first large gear and the outer side of the second large gear. When the intermediate shaft assembly rotates, the inward oil inlet speed of the oil baffle plate is equal to the outward oil throwing speed of the first large gear and the second large gear; and the oil surface thickness of the inner wall of the large-diameter shell reaches the main set thickness. The invention further discloses a gearbox comprising the above oil baffle plate. According to the oil baffle plate and the gearbox, the oil baffle plate is used for achieving different oil invasion surface heights of the large-diameter gear and the small-diameter gear, and the problem that the oil stirring losses of large-diameter gears are large is solved.
Description
technical field [0001] The application relates to the technical field of automobile transmission, in particular to an oil baffle and a gearbox for realizing unequal oil levels. Background technique [0002] At present, inside the existing gearbox, there are multiple pairs of gear transmissions, and the multiple pairs of gear transmissions are arranged along the intermediate shaft of the gearbox. Since the gear transmission needs to perform meshing movement, in order to prevent serious wear of the gears, it is necessary to add lubricating oil to the gear mechanism. Lubrication, so that each pair of meshing gears can be lubricated by lubricating oil. [0003] In the related technology, multiple pairs of gears are coaxially arranged on the intermediate shaft at intervals, and the multiple pairs of gears are large and small. In order to achieve a good lubrication effect, the lubricating oil not only needs to penetrate the large-diameter gears, but also needs to penetrate the sma...
