Background technique
In order to control wet operation clutch or double clutch, according to current technical merit, hydraulic fluid clutch sleeve by costliness in the oil supply is transmitted on the clutch by rotary converter.Here the end on observation that is supported on of clutch realizes that in the back in oily transition piece zone this just strengthens the axial arrangement space requirement in disadvantageous mode.
For lubricating and cooling agent is transported on the clutch, its in double clutch gearbox, in the mode of execution of driving mechanism, pass whole gearbox by jack shaft be transmitted to the opposed side of driving mechanism on and come out therefrom to be transmitted to driving mechanism again by intermediate solid drive shaft.The transition from the jack shaft to the transmission shaft here realizes by the rotary converter of a costliness.
It is open by patent documentation DE 10004186A1 for example to be used for the multi-clutch device settled between the Transmitted chains gear unit of automobile and gearbox, wherein, for transmitting torque between gear unit and gearbox, clutch device has attaches troops to a unit in the first clutch system of the first speed change input shaft of gearbox and attaches troops to a unit in the second clutch system of the second speed change input shaft of gearbox.In known multi-clutch device, one of clutch system has the piston of controlling of at least one restriction pressure chamber, be used to control clutch system, be preferred for by pressure medium, hydraulic medium preferably, start clutch, wherein control piston pressure chamber is separated from the centrifugal force pressure balance chamber of attaching troops to a unit, described centrifugal force pressure balance chamber holds the pressure balance medium.
From the known following gearbox of the present art, needed pump is constituted as the off-axis pump and the spur gearing by trunnion shaft displacement drives for the hydraulic pressure of assembly is supplied in described gearbox, and this spur gearing generally constitutes the straight-tooth gear (driving wheel of pump) engagement, that have the clutch side drive and the spur wheel level of driven gear.
Summary of the invention
Task of the present invention is, a kind of be the clutch supplying hydraulic fluid wet operation, that have the pump drive element of gearbox and/or the method for cooling and oiling agent are provided, can avoid being used for by described Supply Method the conductive liquid hydraulic fluid costliness clutch sleeve and pass the bothersome ground of whole gearbox, transmission cooling and oiling agent.In addition, hydraulic slip should minimize and avoid the axially-extending of gearbox.
This purpose is achieved according to the invention through the features of claim 1.Other make and advantage are drawn by appurtenance.
Therefore a kind of be the clutch supplying hydraulic fluid wet operation, that have the pump drive element of gearbox and/or the method for cooling and oiling agent are proposed, wherein clutch is settled around the axle outside, that be embodied as hollow shaft, is used for the pipeline of hydraulic fluid and hydraulic fluid to the transition piece of clutch and/or be used to cool off and the pipeline of oiling agent and be used for cutting oil and be integrated into the axle that is embodied as hollow shaft to the transition piece of clutch in this.
The pump drive element for example can constitute gear, sprocket wheel, toothed belt wheel, Vee pulley V or friction roller according to the present invention.
Propose in the present invention has the mode of execution scope of advantage, the bearing that supports clutch is placed in below the pump drive element radially observing, and is bearing on the axle of implementing as hollow shaft with this clutch; Thereby the axial arrangement space saves in the transition piece zone of hydraulic fluid and/or cooling and oiling agent.
Propose by foundation the present invention, pipeline in the axle that is embodied as hollow shaft integration and the bearing by supporting clutch radially observe be placed in the pump drive element below, make clutch sleeve obtain simplifying in mode with advantage.
According to the present invention is that the clutch supplying hydraulic fluid wet operation, that have the pump drive element of gearbox and/or the method for cooling and oiling agent can realize in each wet operation clutch, for example also can be in double clutch, particularly in the double clutch of double clutch gearbox, realize, the axle that wherein constitutes hollow shaft in this case is expressed as the outer transmission shaft of attaching troops to a unit in a clutch of double clutch, by intermediate solid drive shaft of this transmission shaft guiding, this intermediate solid drive shaft is attached troops to a unit in another clutch.
Description of drawings
Exemplarily the present invention is described in detail by accompanying drawing below.
Wherein
Fig. 1 illustrates double clutch and by the schematic sectional view of the system layout of the hydraulic fluid of prior art level supply;
Fig. 2 illustrate double clutch and by the schematic sectional view of the system layout of hydraulic fluid of the present invention supply and
Fig. 3 illustrates double clutch and by the schematic sectional view of the system layout of hydraulic fluid of the present invention and lubricating and cooling agent supply.
Embodiment
The mode of operation of wet operation clutch or double clutch and general structure are that the professional person knows, and therefore the structural member that has meaning for the present invention is described below.
Learned that by Fig. 1 the bearing 5 that is used to support clutch is settled the back in following zone at end on observation, rotary converter 4 is being settled in described zone, has therefore increased axial structure space requirement in disadvantageous mode.Another bearing 6 that is used to support clutch is arranged on before the zone of settling rotary converter 4 at end on observation.In addition, the outer transmission shaft of implementing as hollow shaft marks with 8 with 7 marks with by the intermediate solid drive shaft that hollow shaft 7 guides in the drawings, and each transmission shaft 7,8 is all attached troops to a unit in a clutch of double clutch 1 here.
Embodiment is designed to shown in figure 2, the bearing 5 that supports clutch radially observe be placed in pump drive wheel 2 below and be supported in outside on the transmission shaft 7.By design of the present invention, clutch sleeve 3 is simplified and obtains the axial structure space.Here the structure space that obtains by bearing setting of the present invention marks with 9.
In the embodiment shown according to favourable mode, be used for the pipeline 10 of hydraulic fluid and be used for hydraulic fluid transmission shaft 7 outside the transition piece 4 of clutch 1 is integrated into; Transition piece for example can be realized by rotary converter 4.
Another embodiment shown in Fig. 3, in this embodiment in addition for hydraulic fluid conduit 10 and be used for hydraulic fluid to the transition piece 4 of clutch 1 be incorporated into outer transmission shaft 7 and for the bearing 5 that will support clutch radially observe be arranged to pump drive take turns 2 below, the structure space 9 of acquisition so (see figure 2) will be for cooling off and oiling agent carries out the transition on the clutch 1 and uses.
Here be set to, be used for cooling off and the pipeline of oiling agent and be used to cool off and the transition piece 11 of oiling agent is incorporated into outer transmission shaft 7 equally, therefore avoid lubricating cooling oil to pass the gearbox transmission in an advantageous manner, consequently reduce manufacturing expense and assembly fee and use.Transition piece 11 can be embodied as rotary converter in a preferred manner.
