Description
Technical Field
The utility model relates to an automotive transmission field, concretely relates to derailleur lubricating arrangement.
Background
The low cost and high performance of transmission lubrication structures in automotive power performance are one of the indicators of concern to most consumers. Lubrication of prior art transmission lubrication devices is accomplished by a split lubrication device that is separately mounted to the transmission housing. As shown in fig. 1, the transmission lubricating device comprises a transmission housing 1, an oil collecting tray 2 and a shafting assembly 3, wherein the oil collecting tray 2 is independently installed on the transmission housing 1, the oil collecting tray 2 in the whole transmission lubricating device is a plastic thin-wall part, and lubricating oil enters an axial hollow space of the shafting assembly 3 through the dredging of the oil collecting tray 2 and then is injected into gears in the transmission through oil holes formed in the shafting assembly 3.
Because the oil collecting tray 2 is a plastic thin-wall part, the oil collecting tray is difficult to deform during assembly, the assembly efficiency is seriously influenced, the automatic production is not facilitated, and the cost is high. Therefore, there is a need for a transmission lubrication device that allows for a simple assembly of the lubrication structure, improves assembly efficiency, and is less costly.

Furthermore, the protruding lubricating oil guide groove is defined by an inner arc-shaped semicircular surface, an outer arc-shaped semicircular surface and a top semicircular surface between the inner arc-shaped semicircular surface and the outer arc-shaped semicircular surface.
Further, the height of the oil guide rib plate is 3-4 mm.
Furthermore, the axial center hole of the shafting assembly 3 is provided with a lubricating oil inlet on the opposite convex semicircular surface side.
Further, the shafting component is a transmission input shaft.
Further, the transmission housing is of an aluminum die-casting structure.
The utility model discloses beneficial technological effect does: the oil guide rib plate and the protruding lubricating oil guide groove are integrated on the transmission shell and combined into an integral transmission oil guide lubricating device, the assembly process is optimized by the improved transmission lubricating device, the problem of difficulty in assembly is solved, the production efficiency is improved, and the cost is reduced.
Drawings
FIG. 1 is a block diagram of a prior art transmission lubrication system;
FIG. 2 is a structural diagram of the lubricating device of the transmission of the present invention;
FIG. 3 is a partial block diagram of the transmission housing;
the transmission comprises a transmission shell 1, oil guide rib plates 1-1, an inner arc-shaped semicircular surface 1-2, a top semicircular surface 1-3, an outer arc-shaped semicircular surface 1-4, a bottom plane 1-5, an oil collecting disc 2 and a shafting assembly 3.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
Referring to fig. 2 and 3, the utility model discloses a transmission lubricating device, including transmission housing 1, bottom plane 1-5, oil guide plate 1-1 and protruding lubricated oil guide groove, bottom plane 1-5 forms an organic whole with transmission housing 1, and oil guide plate height is 3-4mm and it extends on the bottom plane, and oil guide plate end is just to the axial centre bore of shafting subassembly 3, and protruding lubricated oil guide groove stretches into the axial centre bore of shafting subassembly 3 from oil guide plate end.
The shafting assembly 3 is typically a transmission input shaft. The transmission housing 1 is of an aluminum die-casting structure and then is machined.
The protruding lubricating oil guide groove is formed by enclosing an inner arc-shaped semicircular surface 1-2, an outer arc-shaped semicircular surface 1-4 and a top semicircular surface 1-3 between the inner arc-shaped semicircular surface and the outer arc-shaped semicircular surface. The height of the inner arc-shaped semicircular surface and the height of the outer arc-shaped semicircular surface of the protruding lubricating oil guide groove can be adjusted according to actual use conditions. And the axial center hole of the shafting component 3 is opposite to the convex lubricating oil guide groove side and is a lubricating oil inlet.
During assembly, only the axial center hole of the shafting assembly 3 is aligned to the protruding lubricating oil guide groove of the transmission shell 1, and the assembly is guaranteed to be in place.
When the transmission shaft assembly works, lubricating oil enters the cavity of the transmission, then is guided into the protruding lubricating oil guide groove through the oil guide rib plate and the bottom plane, and then is guided into the central hole of the shaft assembly 3 through the protruding lubricating oil guide groove. Because there is an assembly clearance between the transmission shell and the shafting component of the whole transmission lubricating device, and the transmission shell is integrally formed with the oil guide rib plate and the protruding lubricating oil guide groove, the oil storage and guide effects are achieved.
The transmission lubricating device not only optimizes the assembly process and solves the problem of difficult assembly, but also improves the production efficiency and reduces the cost.
