Embodiment
Following being described in only is exemplary in essence and is intended to limit the disclosure, application by no means or uses.
Referring now to accompanying drawing, the motor-vehicle transmissions that embodies principle of the present invention illustrates in Fig. 1 and is marked as 10.Transmission device 10 comprises the housing 11 that encapsulates clutch pack 21, and further is included in the sealing and the drainage means 31 at the place, bottom of housing 11.When housing 11 partially or completely was submerged in the water, for example, under unexpected flooded conditions, sealing entered into housing 11 with drainage means 31 seal casinghousings 11 to prevent water.In case when flooded conditions was eliminated, sealing allowed water to discharge from housing 11 with drainage means 31.
With reference to Fig. 2 A and Fig. 2 B, sealing comprises columniform hole 12 with drainage means 31, and this hole 12 has the conical surface 13 that is machined in the housing 11.Sealing for example further comprises light ball 14(with drainage means 31, is made by plastic material or rubber), this ball 14 is arranged in hole 12.Ball 14 is besieged in hole 12 by plate 15.Plate 15 can for good and all be attached to housing 11 by piling operation or press-fit operation.Or plate 15 can be by going into plate 15 screwed to be attached in the housing 11 housing 11 to provide entry port and maintainalbility to ball 4.Plate 15 comprises the opening 16 with diameter X and comprises one group from opening 16 outward extending sealing 16A.
When flooded conditions took place, water entered hole 12 by the opening in plate 15 16.Ball 14 floats and moves to sealing station (2) from position of rest (1), the conical surface 13 of ball 14 contacts in hole 12 in this position, thus anti-sealing enters housing 11.If the time of one elongated segment takes place to continue in overflow, then some water may enter regional 21(Fig. 1 of clutch pack).When overflow situation finish and drawdown to sealing station (2) when following, along with water is discharged from hole 16, ball 14 floats on the water and reduces its position to position (1), contacts until ball 14 till the plate 15 of circumference of wound holes 16.Any water that has entered clutch housing 11 flows out from housing 11 and hole 12 by the sealing 16A around opening 16.
Generally speaking, in order to keep suitable function, conical surface 13 and ball 14 are not subjected to the pollution of dust, mud etc.Usually, during the normal running situation and during overflow situation, the bottom of housing 11 is exposed to pollutant.Therefore, at sealing and drainage means 131(Fig. 3 A and Fig. 3 B) another arrange, comprise anti-pollution feature.Particularly, sealing comprises the plunger assembly 22 with spring 19 with drainage means 131.Plunger assembly 22(Fig. 4) also comprises outer stopper 17 and interior stopper 18.Again, ball 14 is placed on the inside in hole 12.Use board component 15A blind hole 12(Fig. 4).In the mode of execution shown in Fig. 3 A and Fig. 4, board component 15A includes plate 15, plunger assembly 22 and spring 19.
Board component 15A by assemble in the opening 16 that interior stopper 18 is inserted into plate 15 (referring to, for example, Fig. 2 B and Fig. 4), then spring 19 is dropped on the plate 15, in outer stopper 17 slided on the stopper 18, until one group of lock-in feature part 18a(Fig. 5) with outside till stopper 17 engages.In alternative arrangement, sealing and drainage means 231 comprise that lock-in feature part such as pin 111 is to lock together outer stopper 17 and interior stopper 18, as shown in Figure 6.
Contain ball 14 and the board component 15A that is besieged in hole 12 in sealing shown in Fig. 3 A and drainage means 131.Ball 14 is maintained at the inside in hole 12 by the spring 20 that is positioned at plunger assembly 22 tops.Board component 15A can be attached to housing 11 by board component 15A being driven piles or being press fit in the housing 11.Alternatively, board component 15A can be bolted in the housing 11 to allow removing of board component 15A, makes that ball 14 and plunger assembly 22 can be keeped in repair.
Under assembling condition, spring 19 upwards promotes plunger assembly 22, makes the outer flange surface 18b contact plate 15 of inner plunger 18.Therefore, opening 16 is sealed with protection hole 12, ball 14 and plunger assembly 22 and is avoided polluting.In addition, notice that the plunger assembly 22 in the position that makes progress allows water to flow into and becomes slow in the hole 12 under overflow situation.
When flooded conditions took place, water entered hole 12 by the opening in plate 15 16.Ball 14 floats and moves to sealing station from position of rest, the conical surface 13 of ball 14 contacts in hole 12 in this position, thus anti-sealing enters into housing 11.When flooded conditions finish and drawdown to sealing station when following, along with water is discharged from hole 16, ball 14 floats on the water and reduces its position.Note, when overflow situation is alleviating and during on every side drawdown, act on hydraulic head on the interior stopper 18 of plunger assembly 22 and make spring 19 compressions and plunger assembly 22 is moved down, from housing 11, discharge further to help water.Any remaining water flows out from housing 11 and hole 12 by the sealing 16A around opening 16.
Between the on-stream period of vehicle, because road interaction and vehicle acceleration, so vehicle moves up and down.Because vertical vehicle movement produces inertial force on sealing and drainage means 131, so this vehicle moves and can change into moving of sealing and drainage means 131.Therefore, plunger assembly 22 inertial force impel spring 19 deflections, and this and then permission stopper 17 and 18 move up and down slightly.Should move to plunger assembly 22 and board component 15A provide self-cleaning type mechanism, the turbidity test of sealing and drainage means further improve in this self-cleaning type mechanism.
In another mode of execution for sealing and drainage means 431 shown in Figure 7, ball 14 and board component 15A arrive the assembly line in free-standing capsule (capsule) C.Sealing can adopt multiple mode to assemble with drainage means 431.For example, the global shell 112 with conical surface 113 can be designed to independent sector and be press fit in the housing 11, board component 15A can be screwed in the housing 11 then.In another was arranged, global shell 112 was attached to board component 15A, is attached to housing 11 as an assembly then.
Description of the invention only is exemplary in itself, and the various modification purports that do not break away from main points of the present invention within the scope of the invention.Such modification is not regarded as departing from the spirit and scope of the present invention.
