As shown in Figure 1 to Figure 3, the utility model embodiment provides a kind of case of transmission assembly, comprises housing 1, and this housing 1 comprises:
Body 20, body 20 comprise diapire 201 and around diapire 201 edges and projection sidewall 202;
Be circular clutch shaft bearing assembly department 2, this clutch shaft bearing assembly department 2 has from the outer side wall of diapire 201 rats;
The second oil baffle 5, the first oil baffles 4 that are the first oil baffle 4 of raised line shape and are raised line shape have the first end connected with the outer side wall of clutch shaft bearing assembly department 2 and second end relative with these the first oil baffle 4 first ends; The second oil baffle 5 has the first end connected with the outer side wall of clutch shaft bearing assembly department 2 and second end relative with these the second oil baffle 5 first ends;
The first oil baffle 4, the second oil baffle 5 and be sandwiched in the first end of the first oil baffle 4 and the first end of the second oil baffle 5 between the outer side wall of clutch shaft bearing assembly department 2 form and to there is second end of oil storage section 6, the first oil baffles 4 of an opening and the opening that the second end of the second oil baffle 5 forms this oil storage section 6;
The first oilhole 7 that is positioned at oil storage section 6 and is connected with clutch shaft bearing assembly department 2.
On housing 1, also comprise differential mechanism gear ring 3, the second bearing assembly department 21 arranging on differential mechanism gear ring installation position and the second oilhole 71 being connected with this second bearing assembly department 21, when differential mechanism gear ring 3 stirs fluid, because oil storage section 6 is for having the cavity of opening, and as much as possible by its opening towards differential mechanism gear ring 3, thereby the fluid that makes to be stirred is convenient to enter in this oil storage section 6 and is stored, and by oilhole 7,71, flow in each bearing assembly department being connected 2,21, guarantee that bearing 14 can access the lubricated of fluid.
In order to realize fluid, be convenient to collect and store, in the design, require the quantity that oil storage section 6 arranges to lack as much as possible (as one), all oilholes also as far as possible in a relatively concentrated region, and only need guarantee that in this region, having fluid to soak covers, rather than are the bigger the better.Meanwhile, for fear of fluid, collect for the moment too much, and fluid is flowing always, cause the directly 6 interior losses from oil storage section, as an example, case of transmission assembly also sets up and holds oiled-plate method 8 and protect on housing 1, and this holds the top that oiled-plate method 8 is arranged on housing 1 oil storage section 6.Hold that oiled-plate method 8 can be threaded connection or rivet etc. mode and housing 1 fixes.As an example, on housing 1, set up three for the tapped hole 12 with holding oiled-plate method 8 and fixing, case of transmission assembly also comprises bolt 13 and will hold oiled-plate method 8 and be fixed on the top of oil storage section 6 by bolt 13.
Even, the first oil baffle 4, the second oil baffle 5 and clutch shaft bearing assembly department 2 threes are consistent from the height of housing 1 diapire 201 projections, hold oiled-plate method 8 be installed on this oil storage section 6 above time, this holds oiled-plate method 8 and the first oil baffle 4 and the second oil baffle 5 and fits, thereby can guarantee that fluid is well stored in this oil storage section 6.
When differential mechanism gear ring 3 stirring fluid get rid of oil storage section 6, body 20 keeps off the fluid splashing return by sidewall 202, then from the opening of oil storage section 6, flows in oil storage section 6, so that fluid is further collected.
In order to be conducive to that the fluid that splashes to sidewall 202 can be incorporated in oil storage section 6, to be provided be all the first oil guide plate 9 and second oil guide plate 10 of raised line shape on diapire 201; Wherein, the first end of the first oil guide plate 9 connects a side of sidewall 202, and the second end connects the second end of the first oil baffle 4; The second oil guide plate 10 and the second oil baffle 5 are all positioned at the side near differential mechanism gear ring 3, the first end of this second oil guide plate 10 is connected with a side sidewall 202 that is connected the first oil guide plate 9, a reserved fluid entrance 11 between the second end of the second end of the second oil guide plate 10 and the second oil baffle 5, this fluid entrance 11 is as far as possible towards differential mechanism gear ring 3.Now, fluid has two kinds of modes to enter in oil storage section 6: after one, the fluid that splashes to housing 1 sidewall 202 are blocked, flow in oil storage sections 6 (as shown in arrow a in Fig. 3) respectively along the first oil guide plate 9 and the second oil guide plate 10; The fluid that two, differential mechanism gear ring 3 stirs is directly flowed through this fluid entrance 11(as shown in arrow b in Fig. 3), thus the 6 interior storages in oil storage section.
Further, the second oil baffle 5 cross section outlines are L-type, comprise interconnective header board 51 and rear plate 52, and header board 51 is connected with the outer side wall of clutch shaft bearing assembly department 2 away from one end of rear plate 52, rear plate 52 away from one end of header board 51 towards the second oil guide plate 10.Because plate 52 after in L-type the second oil baffle 5 is 6 interior bendings towards oil storage section, can stop that like this fluid that is back to oil storage section 6 from the first oil guide plate 9 and the second oil guide plate 10 more enters oil storage section 6, rather than directly flow out oil storage section 6.
Further, when the first oilhole 7 is convex, the height of projection of rear plate 52 reduces gradually along the direction away from header board 51, and the height of projection higher than the first oilhole 7, certainly, when the second oilhole 71 is convex, the height of projection of rear plate 52 reduces gradually along the direction away from header board 51, and the height of projection higher than the second oilhole 71, therefore no matter how the height of rear plate 52 changes, can guarantee that the fluid of collecting can soak covers each oilhole, thereby make bearing 14 obtain enough fluid, is lubricated.
Case of transmission assembly corresponding to the utility model embodiment one, the utility model embodiment two provides a kind of automobile, have the case of transmission assembly described in the utility model embodiment one, the formation of this case of transmission assembly and annexation etc. repeat no more herein.
Implement the utility model embodiment, there is following beneficial effect:
1, due in the utility model embodiment, oilhole is all arranged on the outside of each bearing assembly department, can not destroy the full circle shape of bearing assembly department, when bearing and bearing assembly department are assembled together, shaft strength is evenly distributed, thereby improved the noise producing between speed changer inner bearing and bearing assembly department, the working life of having improved bearing;
2, due in the utility model embodiment, the first oil baffle, the second oil baffle and and the outer side wall that is sandwiched in the clutch shaft bearing assembly department between the first end of the first oil baffle and the first end of the second oil baffle form oil storage section, and all oilholes are all positioned at this oil storage section, the fluid that the fluid stirring by differential mechanism gear ring and housing sidewall are collected all enters this oil storage section, make bearing have lasting fluid to be lubricated it, thus the working life of having improved bearing.
Above disclosed is only a kind of preferred embodiment of the utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim, still belongs to the scope that the utility model is contained.
