Abstract
The utility model discloses a planet gear lubricating device of an automatic transmission. The device comprises a clutch hub and a planet gear, the planet gear is provided with a planet gear shaft, a lubricating oil passage is arranged in the planet gear shaft, and a pocket oil plate is arranged in the clutch hub; the pocket oil plate is welded with the inner wall of the clutch hub, and the pocket oil plate, the clutch hub and the planet gear form a pocket oil passage; and the pocket oil passage is communicated with the lubricating oil passage, and the clutch hub is fixedly connected with a planet carrier of the planet gear. By adopting the technical scheme, compared with the prior art, the device has the advantages that the pocket oil plate is welded in the clutch hub, the clutch hub can be separately machined, and the clutch hub is simple in structure and can be machined by stamping or spinning, so that the device is easy to machine and high in production efficiency; the pocket oil plate can be separately stamped, so the device is low in production cost and high in production efficiency; and the device is suitable for batch production.
Description
Technical field
The utility model relates to a kind of automatic transmission, specifically, relates to a kind of automatic transmission planet wheel lubricating fitting, belongs to field of mechanical technique.
Background technique
In traditional multidrive; For the planet wheel 3 among the planet row is lubricated, need the oil duct 4 of special to lubricate planet wheel 3, like Fig. 1, shown in Figure 2 through planet wheel shaft 2; Pocket oil ear 5 so just need be set on clutch hub 1, be used for oil storage with lubricated planet wheel 3; For reaching the purpose that planet wheel 3 is lubricated, clutch hub 1 need be set to integrative-structure with pocket oil ear 5, can only realize through machining like this, increased cost of production, and working efficiency is low, is not suitable for volume production.
The model utility content
The technical problem that the utility model will solve is to above deficiency, and a kind of processing, automatic transmission planet wheel lubricating fitting that manufacturing efficiency is high of being easy to is provided.
For solving the above problems; The utility model adopts following technological scheme: a kind of automatic transmission planet wheel lubricating fitting, comprise clutch hub, planet wheel, and planet wheel is provided with planet wheel shaft; Be provided with oil leab in the planet wheel shaft, it is characterized in that: be provided with the pocket oiled-plate method in the said clutch hub; The inwall of pocket oiled-plate method and clutch hub is welded to connect, and pocket oiled-plate method and clutch hub, planet wheel form pocket oil oil duct; Pocket oil oil duct is communicated with oil leab.
Further improvement as technique scheme: said clutch hub is fixedly connected with the planet carrier of planet wheel.
The utility model is taked above technological scheme, compared with prior art, has the following advantages: welding pocket oiled-plate method in clutch hub; Processing clutch hub separately, clutch hub simple in structure can adopt punching press or spinning to process; Be easy to processing, manufacturing efficiency is high; The impact briquetting separately of pocket oiled-plate method, cost of production is low, and manufacturing efficiency is high; Be fit to produce in batches.
The utility model is described further with implementing below in conjunction with accompanying drawing.
Description of drawings
Accompanying drawing 1 is the structural representation of planet wheel lubricating fitting in the existing technology;
Accompanying drawing 2 is the partial enlarged drawing of accompanying drawing 1;
Accompanying drawing 3 is the structural representation of planet wheel lubricating fitting among the utility model embodiment;
Among the figure, 1-clutch hub, 2-planet wheel shaft, 3-planet wheel, 4-oil duct, 5-pocket oil ear, 6-pocket oiled-plate method, 7-oil leab, 8-pocket oil oil duct.
Embodiment
Embodiment, as shown in Figure 3, a kind of automatic transmission planet wheel lubricating fitting comprises clutch hub 1, planet wheel 3, planet wheel 3 is provided with planet wheel shaft 2, is provided with oil leab 7 in the planet wheel shaft 2, the pocket oiled-plate method 6 that is provided with in the clutch hub 1; Pocket oiled-plate method 6 adopts stamping process to process, and required precision is low, and cost is low, and manufacturing efficiency is high, and pocket oiled-plate method 6 is welded to connect with the inwall of clutch hub 1, and pocket oiled-plate method 6 forms pocket oil oil duct 8 with clutch hub 1, planet wheel 3; Pocket oil oil duct 8 is communicated with oil leab 7, and during the speed changer operation, fluid gets into oil leab 7 along pocket oil oil duct 8 under centrifugal action, planet wheel 3 is lubricated, and clutch hub 1 is fixedly connected with the planet carrier of planet wheel 3.
Those skilled in the art will recognize that; Above-mentioned embodiment is exemplary; Be in order to make those skilled in the art can better understand the utility model content; Should not be construed as is the restriction to the utility model protection domain, so long as the improvement of being done according to the utility model technological scheme, all falls into the protection domain of the utility model.
