More particularly, Fig. 1 shows the selected parts of the electrically-variable transmission 10 of the main casing 14 that contains input housing 12 and have two electric notors (A and B), by a series of planetary gear set (not shown), described selected parts directly by bearings on the main shaft 19 of transmission device 10.(A is B) by selecting the oncoming clutch (not shown) to make output shaft 20 rotations for described motor.This oil-collecting disk 16 is arranged on the base of main casing 14 and is configured to be provided for the oil mass of transmission device 10 and its assembly.The projection line P-P of this oil-collecting disk 16 defines the necessary ground Clearance that is used for vehicle, as shown in Figure 1.These main casing 14 covering such as electric notors (A, B), planetary gear construction, the innermost parts of the transmission device of main shaft 19 and two clutches (all exemplarily provide and all do not illustrate).At last, these input housing 12 bolts are directly connected on the engine bearer rear surface of this motor 24 (Fig. 2 illustrates), and sealing transmission component, described transmission component and motor 24 mechanical connections.That is to say that this output housing 12 covers this torsional damper assembly 26 (shown in Figure 2).This output housing 12 also supports service pump 27 (shown in Fig. 1 and 3), and this service pump 27 is installed on the base of input housing 12 and is adjacent to nested fixing and on this projection line P-P with oil-collecting disk 16.
The moment of torsion of not expecting that torsional damper assembly 26 shown in Fig. 2 generally is used to transmission device 10 and motor 24 are produced is during operation isolated, and is starting and also optionally auxiliary drive electric notor (A or B) elimination engine pressure pulse of stopping period.This torsional damper assembly 26 comprises motor side lid 28, and this side lid 28 is connected on the engine crankshaft 29.This motor side lid 28 is welded on the transmission device side lid 30 and 31 and holds this absorber spring 32.Described two lids (28 and 30) define container 34, these container 34 this lock-up clutch 33 of sealing and pistons 50.This torsional damper assembly 26 also holds the shock absorber flange 38 with hub portion 40, and this hub portion 40 cooperates with the spline 42 of input shaft 18 in complementation.The motor side lid 28 of torsional damper 26 is connected on the motor corrugated sheet 44.This corrugated sheet 44 is used for being delivered to the moment of torsion that motor 24 produces on the transmission device and being used to absorb any thrust load that is produced by bumper assembly 26.This torsional damper assembly 26 comprises a series of absorber spring 32, and this spring 32 is annular or extending circumferentially between motor side lid 28 and transmission device side lid 30.This absorber spring 32 absorbs and cushions by motor 24 at the moment of torsion of not expecting normal or drive pattern operation period generation.The Maximum Torque that this torsional damper assembly 26 has equals this maximum engine torque and adds that some allow surplus.This torsional damper assembly 26 can be configured to partly be similar to the structure that discloses at the U. S. Patent of owning together 5009301, and this patent here integral body is incorporated herein by reference.
This electrically-variable transmission 10 is provided with two electric notors (A and B are shown in Fig. 1).Set up moment of torsion in startup and stopping period electric notor A, offset effectively at motor to be lower than the engine pressure pulse that 600rpm (perhaps starting and/or halted state) causes when turning round.The absorber spring 32 of this torsional damper assembly 26 is by application (this lock-up clutch 33) clutch disk 36 when motor 24 turn round in predetermined speed range and 37 and locked.In a preferred embodiment, when motor turned round with the speed that is less than or equal to 600rpm, this torsional damper assembly 26 was locked effectively.Because electric notor in electrically-variable transmission (A or B) can both be used for initiatively offsetting in the engine pressure pulse that starts and stopping period produces, therefore this operation mode is expected.
Lock-up clutch 33 in torsional damper assembly 26 inside comprises that two 37, two of actuator discs that are connected on this shock absorber flange 38 are connected to the friction disk 36 on the transmission device side lid 30, backing plate 46 and the snap ring 48 that is connected to shock absorber flange 38.This lock-up clutch 33 comprises hydraulic piston 50, and this hydraulic piston 50 moves against this actuator disc 37, forces actuator disc 37 to engage with friction disk 36.Described piston 50 is in response to supplying to the oil the oil pocket 58 from oil circuit 57 and moving.This load is applied at backing plate 46 and snap ring 48 places and is held by shock absorber flange 38.Near piston 50 and the vibration damper wheel hub 40 that is connected to the torsional damper assembly 26 of shock absorber flange 38 have the passage 56 of lateral bore, thereby limit the opening 52 that radially extends, the oil that this opening 52 receives from oil circuit 57.This piston 50 is limited to cooperate with lock-up clutch 33 and remained on disengaged position by returning spring 54.Because oil is provided between the outer diameter of the inner diameter of input shaft 18 and steel wheel hub 35, arrive the opening 52 of vibration damper wheel hub 40 by the opening 53 of input shaft 18, and enter into the passage 56 of this vibration damper wheel hub 40, pressure in piston cavity 58 increases, set up and enough overcome spring force and make piston 50 carry out the load of stroke, thereby engaged this lock-up clutch 33.This container 34 also is equipped with the oil (by service pump 27 shown in Fig. 1 and 3 or main pump 55 pumpings shown in Figure 1) from oil hydraulic circuit 59.Described oil passes through the inner diameter of the pipe 35 in the inner diameter that is installed in input shaft 18 from opening 52, and passes through the thrust washer 41 (perhaps pad) of trough of belt, enters into the chamber or the space 43 of container 34 inside.Therefore the oil that holds in container 34 advances to piston 50 right sides, as shown in Figure 2, so as during the predetermined operation mode when expecting not use this clutch (engine speed is more than the 600rpm) contend with and be fed to oil in the cavity 58 on piston 50 opposite sides.
This oil hydraulic circuit 57 and 59 provides oil respectively in piston cavity 58 and vibration damper container 34 as shown in Figure 2; Control lock-up clutch 33 and control it and in predetermined condition, cooperate and throw off.These first loop, 57 last hydraulic fluids that provided by service pump 27 of carrying are in piston cavity 58.By carrying out stroke and engage this lock-up clutch 33, the high pressure of the increase that causes in response to oil at this piston 50 of the inside of torsional damper assembly 26 by 57 supplies of first loop, thus effectively lock this absorber spring 32.When this lock-up clutch 33 engaged, torsional damper spring 32 was released or is locked so that this motor 24 is directly connected to the input shaft 18 of transmission device 10.This situation only is preferred for engine start and stops that (promptly start and/or stop mode, wherein engine speed is in predetermined speed range: 0-600rpm).
When main pump 55 is not worked, can obtain the main pump 27 shown in oily this second loop 59 use Fig. 1 and 3 from main pump 55 or service pump 27.This second loop 59 is provided to piston 50 right sides (perhaps the vibration damper container 34) as shown in Figure 2 with oil, thus this piston 50 of hydro-cushion.Oil advances to the inner diameter of steel pipe 35 by opening 51, and the thrust washer 41 (perhaps pad) by trough of belt enters into space 43 and enters into vibration damper container 34.
When motor stopped, the main pump 62 that obtains power from motor was not worked.Because vibration damper container 34 is sealing not, when this main pump 55 and service pump 27 were not worked, inner oil leaked up to approximately half-full from vibration damper container 34.The centrifugal load that the rotation of input shaft 18 and torsional damper assembly 26 causes forces the periphery of remaining oil to torsional damper assembly 26.Similarly, the oil that is present in shock absorber flange 38 is compulsorily entered in the piston cavity 58 (that is its periphery).Because the oil in shock absorber flange 38 is concentrated in piston cavity 58, therefore the oily weight in piston cavity 58 is on this piston 50.Down high-speed, the centrifugal load on the oil in piston cavity 58 can overcome the power of returning spring 54 and make piston 50 carry out stroke.In a preferred embodiment, the pressure difference between piston cavity 58 and vibration damper container 34 must be greater than or equal to the 4psi that overcomes returning spring, perhaps is greater than or equal to the 60psi that obtains complete moment of torsion hold facility on clutch 33.Effective locking of the joint of this lock-up clutch 33 and this torsional damper assembly spring 32 can cause the additional wear on transmission component, if take place in the predetermined speed range outside, causes the life cycle of premature failure or reduction.
A technical advantage of the present invention is, as shown in figs. 1 and 3, service pump 27 is configured such that when this motor 24 stops, and provides oil (perhaps hydraulic fluid) to this torsional damper assembly 26, thereby provide transmission cluthes pressure, damper clutch pressure and lubricated.Service pump 27 and main pump 55 provide oil in the remainder of this vibration damper 34 in addition.In a preferred embodiment, service pump 27 is the internal gear pumps that driven by electric notor C, as shown in Figure 3.As shown in Figure 1, this service pump 27 is (the perhaps imaginary line of extrapolating from the bottom of oil-collecting disk 16) nestedly near this oil-collecting disk 16 and on this projection line P-P of oil-collecting disk, makes this pump 27 not need the ground Clearance of adding.
This service pump 27 is fastened on the bottom of input housing 12 by having suction line 66 and pressure line 64 ABAP Adapter housing 62 as shown in Figure 3.This ABAP Adapter housing 62 is fastened on the input housing 12 and with auxiliary suction line 66 and aux. pressure line 74 by structure connector (perhaps bolt 65) and separates, and described auxiliary suction line and aux. pressure line all extend between service pump 27 and input housing 12.This service pump 27 is installed on the input housing 12 so that as close as possible this oil sump and be arranged in the control module of this oil-collecting disk 16, as shown in Figure 1, thereby makes the line loss on the suction line of this pump 27 and pressure line (shown in Figure 3 66 and 64) lose minimum.Oil is filtered and be extracted in the service pump 27 from this oil sump (the perhaps oil sources the oil-collecting disk 16) by auxiliary suction line 66.Then pressure oil is pressed onto in this transmission device controller 60 (as shown in Figure 2) by this ABAP Adapter housing pressure line 64, feeds back in this input shaft 18 by first oil hydraulic circuit 57 at last.
Although described enforcement the preferred embodiments of the present invention in detail, it will be appreciated by those skilled in the art that within the scope of the appended claims and can carry out different designs.
