Description

The normal wet clutch that engages
Technical field
The present invention relates to a kind of normal joint wet clutch being applicable on various vehicles, particularly car.
Background technique
Clutch is the vitals in transmission system transferring power process, and it is along with the passed by course of last 100 years of the birth development of vehicle.The Main Function of clutch comprises the starting of assurance automobile balance, realizes smooth-going gear shift, prevents power train overload etc., is one of critical piece of speed changer, and clutch is divided into dry type and wet type by the working environment of rubbing surface.
Take in the automobile mechanical power train that internal-combustion engine is power, the head end of clutch in power train, being the important component part of automotive transmission, is also in vehicle traveling process, to use parts frequently to engage frequently and sliding wear, for dry clutch, the heat producing raises the temperature of the parts such as clutch compressing disc and flywheel, thereby aggravated the wearing and tearing of friction plate, reduced the working life of clutch, dry clutch is in the process of combination simultaneously, impact greatlyr, affect riding comfort.
Wet clutch is compared with dry clutch and is mainly contained following advantage:
(1) surface area is large, therefore the moment of torsion transmitting is also large.Do not increasing under the prerequisite of radial dimension, can with increase friction plate number, improve the torque of transmission, can also change the size of exerting pressure, capacity is reconciled operation torque as requested, is convenient to realize seriation and generalization.A plurality of friction pairs are worked simultaneously, and friction torque is large, can transmit reliably the peak torque of motor.
(2) more smooth-going, soft while engaging, while making Vehicle Driving Cycle, shake and impact reduce.
(3) even wearing and do not need special adjusting strip gap.
(4) Friction Disk Surface compressive load per unit area is evenly distributed.
(5) transmission shaft is not had to radial load, friction element stressing conditions and irrelevant to rotation direction.
Existing wet clutch is all normal open form formula, and, under not oil-filled state, clutch is in separated state.And the dry clutch of applying on present vehicle all belongs to normal jointing state, this new-type clutch just on this basis, makes wet clutch into normal engaging clutch, to better being promoted on vehicle.
Summary of the invention
The object of the invention is to, for the life-span of solution dry clutch in existing vehicle drive system is short and impact larger problem, propose a kind of novel normal joint wet clutch, to substitute the application of dry clutch on vehicle, improve usability and the cornering ability of vehicle.
The present invention often engages wet clutch, comprise the airtight cavity being formed by housing and end cap, by bearing, be arranged on pto=power take-off and the input shaft on housing and end cap respectively, the driven clutch hub setting firmly respectively on the axle head of output shaft and input shaft and initiatively clutch hub, on the inwall of driven clutch hub by the driven friction disk of spline joint, on the outer wall of active clutch hub by the active friction plate of spline joint, rest on the thrust disc on driven friction disk end face and pass into the oil line pipe that lubricant oil is provided in airtight cavity; Arranged outside one diaphragm spring at described thrust disc, the pretension bolt being provided with as balance pivot by the supporting frame being installed on described driven clutch hub is connected on the outer wall of diaphragm spring, by thrust-bearing, be arranged on the inner edge place that piston on the described input diameter of axle is connected to diaphragm spring, by adjusting pretension bolt, make described driving and driven friction plate in normal jointing state.
The present invention often engage wet clutch in working order under, effect due to the pretension bolt as balance pivot, driving and driven friction plate is in normal jointing state, friction plate is compacted and realize power transmission, when needs cut off power transmission, only need provide certain pressure to piston, now piston promotion diaphragm spring turns an angle around its balance pivot pretension bolt, the pressure that diaphragm spring imposes on thrust disc disappears, thereby reaches clutch separation.After the pressure of piston disappears, the elastic force effect due to diaphragm spring, is returned to impaction state, and now clutch is re-engaged.
This structure is that the torque range that wet clutch transmits is larger in order to replace dry clutch to design, can be according to the torque demand of different vehicle, and the number that increases or reduce friction plate realizes, and can adapt to the application of multiple vehicle.Reaching under the prerequisite of dry clutch basic role, can make the life-span of clutch increase, driving comfortability is better.
Accompanying drawing explanation
Fig. 1 is the structural representation that the present invention often engages wet clutch.
Embodiment
The embodiment who provides below in conjunction with accompanying drawing is described in further detail structure of the present invention.
With reference to Fig. 1, a kind of normal joint wet clutch, comprise the airtight cavity being formed by housing 1 and end cap 6, by bearing, be arranged on pto=power take-off 2 and the input shaft 10 on housing 1 and end cap 6 respectively, the driven clutch hub 11 setting firmly respectively on output shaft 2 and input shaft 10 axle heads and initiatively clutch hub 3, on the inwall of driven clutch hub 11, pass through the driven friction disk 12 of spline joint, on the outer wall of active clutch hub 3, pass through the active friction plate 4 of spline joint, rest on the thrust disc 5 on driven friction disk 12 end faces and pass into the oil line pipe that lubricant oil is provided in airtight cavity,
Arranged outside one diaphragm spring 8 at described thrust disc 5, the pretension bolt 7 being provided with as balance pivot by the supporting frame 13 being installed on described driven clutch hub 11 is connected on the outer wall of diaphragm spring 8, by thrust-bearing, be arranged on the inner edge place that piston 9 on described input shaft 10 footpaths is connected to diaphragm spring 8, by adjusting pretension bolt 7, make described driving and driven friction plate in normal jointing state.
In this normal structure that engages wet clutch, have two oil line pipes, one in clutch cover 6, its effect is to provide separated needed oil pressure, i.e. oil circuit control for piston.Another is in input shaft 10 and clutch cover 6, and its effect is to provide lubricated and heat radiation, i.e. oil leab to friction plate.
Under original state, effect due to the pretension bolt 7 as balance pivot, driving and driven friction plate is in normal engagement, friction plate is compacted and realize power transmission, when needs cut off power transmission, only need provide certain pressure to piston 9, now piston promotion diaphragm spring 8 turns an angle around its balance pivot pretension bolt 7, the pressure that diaphragm spring 8 imposes on thrust disc 5 disappears, thereby reaches clutch separation.After the pressure of piston disappears, the elastic force effect due to diaphragm spring, is returned to impaction state, now clutch combination again.
