Embodiment
Following being described in is only exemplary and the certainly not intended to be limiting disclosure, application or use in essence.
Referring now to accompanying drawing, the motor-vehicle transmissions embodying principle of the present invention illustrates in FIG and is marked as 10.Transmission device 10 comprises the housing 11 of encapsulation clutch pack 21, and is included in sealing and the drainage means 31 at the bottom place of housing 11 further.Such as, when housing 11 is partially or completely submerged in water, under unexpected flooded conditions, sealing and drainage means 31 seal casinghousing 11 enter into housing 11 to prevent water.Be eliminated once flooded conditions, sealing and drainage means 31 allow water to discharge from housing 11.
With reference to Fig. 2 A and Fig. 2 B, sealing and drainage means 31 comprise columniform hole 12, and this hole 12 has the conical surface 13 be machined in housing 11.Sealing and drainage means 31 comprise light ball 14(such as further, are made up of 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 be for good and all attached to housing 11 by piling operation or press-fit operation.Or plate 15 is attached to housing 11 to provide entry port and maintainalbility to ball 4 by plate 15 screwed being entered in housing 11.Plate 15 comprises the opening 16 with diameter X and comprises one group from the outward extending sealing 16A of opening 16.
When there is flooded conditions, water is by opening 16 access aperture 12 in plate 15.Ball 14 floats and moves to sealing station (2) from position of rest (1), and in this position, ball 14 contacts the conical surface 13 in hole 12, thus anti-sealing enters housing 11.If the time continuing an elongated segment occurs in overflow, then some water may enter region 21(Fig. 1 of clutch pack).When overflow situation terminate and water level decreasing to sealing station (2) below time, along with water is discharged from hole 16, ball 14 floats on the water and reduces its position to position (1), till the plate 15 of the circumference of ball 14 contact ring around hole 16.Any water having entered clutch housing 11 is flowed out from housing 11 and hole 12 by the sealing 16A around opening 16.
Generally speaking, in order to maintain suitable function, conical surface 13 and ball 14 are not subject to the pollution of dust, mud etc.Usually, during normal operation conditions 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 and drainage means 131 comprise the plunger assembly 22 with spring 19.Plunger assembly 22(Fig. 4) also comprise 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 assembles by being inserted in the opening 16 of plate 15 by interior stopper 18 (see, such as, Fig. 2 B and Fig. 4), then spring 19 is dropped on plate 15, outer stopper 17 is slided on interior stopper 18, until one group of locking feature 18a(Fig. 5) engage with outer stopper 17 till.In alternative arrangement, sealing and drainage means 231 comprise the locking feature of such as pin 111 outer stopper 17 and interior stopper 18 to be locked together, as shown in Figure 6.
The sealing illustrated in figure 3 a and drainage means 131 are containing by the ball 14 of besieging in hole 12 and board component 15A.Ball 14 is maintained at the inside in hole 12 by the spring 20 be positioned at above plunger assembly 22.Board component 15A is by driving piles board component 15A or being press-fitted in housing 11 and being attached to housing 11.Alternatively, board component 15A can be bolted in housing 11 to allow removing of board component 15A, and ball 14 and plunger assembly 22 can be keeped in repair.
Under assembling condition, spring 19 is plunger assembly 22 upwardly, makes the outer flange surface 18b contact plate 15 of inner plunger 18.Therefore, opening 16 is sealed with protective hole 12, ball 14 and plunger assembly 22 from pollution.In addition, note, the plunger assembly 22 in upwards position allows water to flow in hole 12 and becomes slow under overflow situation.
When there is flooded conditions, water is by opening 16 access aperture 12 in plate 15.Ball 14 floats and moves to sealing station from position of rest, and in this position, ball 14 contacts the conical surface 13 in hole 12, thus anti-sealing enters into housing 11.When flooded conditions terminate and below water level decreasing to sealing station time, along with water is discharged from hole 16, ball 14 floats on the water and reduces its position.Note, when overflow situation alleviating and water level decreasing around time, the hydraulic head acted on the interior stopper 18 of plunger assembly 22 makes spring 19 compress and plunger assembly 22 is moved down, and discharges from housing 11 to be conducive to water further.Any remaining water is flowed out from housing 11 and hole 12 by the sealing 16A around opening 16.
Between the on-stream period of vehicle, because road interacts and vehicle acceleration/deceleration, so vehicle moves up and down.Because vertical vehicle movement produces inertial force in sealing with drainage means 131, so this vehicle moves and can change into the movement of sealing and drainage means 131.Therefore, plunger assembly 22 inertial force impels spring 19 to deflect, and this and then permission stopper 17 and 18 move up and down slightly.This moves as plunger assembly 22 and board component 15A provide self-cleaning type mechanism, and this self-cleaning type mechanism improves the turbidity test of sealing and drainage means further.
Be shown in Figure 7 for sealing with another mode of execution of drainage means 431, ball 14 and board component 15A arrive the assembly line in free-standing capsule (capsule) C.Sealing and drainage means 431 can adopt various ways to assemble.Such as, the global shell 112 with conical surface 113 can be designed to independent sector and be press-fitted in housing 11, then board component 15A can be screwed in housing 11.In another is arranged, global shell 112 is attached to board component 15A, is then attached to housing 11 as an assembly.
Description of the invention is only exemplary in itself, and the various modification purports not departing 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.
