Abstract
The invention discloses a kind of crankcase mechanism with wet clutch, comprise crankcase, centrifugal clutch, described centrifugal clutch comprises clutch chamber, it is characterized in that: described centrifugal clutch is arranged on a side of crankcase, the driving link of clutch and the pto of engine crankshaft are connected, and this clutch is a Wet-type centrifugal formula clutch.Beneficial effect of the present invention is that the operation noise is little, and parts are difficult for overheated, and long service life need not to set up extra oil simultaneously, and simple in structure, processing cost is low, operates steadily.
Description
Technical field
The present invention relates to a kind of crankcase mechanism, be applicable to various crankcase mechanisms, be meant the crankcase mechanism of giving the wet type clutch feed in the motorcycle engine especially with wet-type centrifugal clutch.
Background technique
In present stepless speed-change motorcycle engine transmission mechanism, clutch is the outside that places the stepless transmission driven wheel assembly, clutch and stepless speed variator integral body place on the engine driveshaft, because clutch feed is given in structural restriction, it is complicated that the oil duct difficulty is set, therefore clutch often adopts the dry-type centrifugal clutch, but the dry-type centrifugal clutch is not owing to there is lubricant oil to be lubricated cooling, and the operation noise is big, and parts are easily overheated, influence working life.
Summary of the invention
The present invention seeks to overcome the shortcoming and defect of prior art, provide a kind of and be provided with conveniently, the crankcase mechanism of band wet clutch simple in structure.
For achieving the above object, technological scheme of the present invention is, comprise crankcase, centrifugal clutch, described centrifugal clutch comprises clutch chamber, it is characterized in that: described centrifugal centrifugal clutch is arranged on a side of crankcase, the driving link of this centrifugal clutch and the pto of engine crankshaft are connected, and this clutch is a Wet-type centrifugal formula clutch, the pto of described engine crankshaft and crankcase joint are provided with sliding bearing, and the oil duct at sliding bearing place is communicated with pressure oil-source and clutch chamber.This is provided with a side that centrifugal clutch is arranged on engine crankcase, solve the setting of wet-type centrifugal clutch oil duct and be subjected to described structural limitations in the background technique, and it is big to have solved the operation noise that background technique adopts the dry-type centrifugal centrifuge to be brought, parts are easily overheated, the problem that working life is short, and make full use of in the motor sliding bearing oil duct, make the lubricant oil behind lubricated, the cooling sliding bearing can further lubricate, cool off centrifugal clutch, so just need not to set up extra oil to clutch feed, integral body is provided with simply, compact structure.
Further be provided with is that described oil duct comprises from pressure oil-source and enters the oil duct of sliding bearing and flow to oil duct two-part of clutch chamber from sliding bearing, wherein the oil duct that enters sliding bearing from pressure oil-source is oilhole and the oil groove of offering at sliding bearing, and the oil duct that flows to clutch chamber from sliding bearing is to be made of gap between sliding bearing and the engine crankshaft.
Further be provided with is to it is characterized in that described Wet-type centrifugal formula clutch is driving link fixedly to be connected with clutch end engine crankshaft is coaxial.
The invention has the beneficial effects as follows that the operation noise is little, parts are difficult for overheated, and long service life need not to set up extra oil simultaneously, and simple in structure, processing cost is low, operates steadily.
Below in conjunction with specification drawings and specific embodiments the present invention is done further introduction.
Description of drawings
The structural representation of Fig. 1 specific embodiment of the invention
Fig. 2 specific embodiment of the invention I portion enlarged view
Embodiment
The crankcase mechanism of the band wet-type centrifugal clutch shown in Fig. 1-2, comprise crankcase 1, wet-type centrifugal clutch 2, described wet-type centrifugal clutch comprises clutch chamber 3, this wet-type centrifugal clutch 2 is arranged on a side of crankcase 1, wet-type centrifugal clutch driving link 7 is coaxial fixedly sleeved by spline with the pto of engine crankshaft 4, and formation is connected.The output terminal of engine crankshaft 4 and crankcase 1 joint are provided with sliding bearing 5, the oil duct at sliding bearing 5 places is communicated with pressure oil-source and clutch chamber 3, the described oil duct of present embodiment comprises from pressure oil-source and enters the oil duct of sliding bearing and flow to oil duct two-part of clutch chamber from sliding bearing, wherein the oil duct that enters sliding bearing from pressure oil-source is oilhole 8 and the oil groove of offering at sliding bearing 6, the oil duct that leads to clutch chamber from sliding bearing is to be made of gap between sliding bearing 5 and the engine crankshaft, described clutch chamber 3 and crankcase 1 are communicated with, this pressure oil-source is that the oil pump pushing of motor produces, oil pump is lubricated earlier by oil duct with lubricant oil, cooling sliding bearing 5, further be ejected into clutch chamber 3, clutch driving link 7 is lubricated, cooling, because lubricant oil is ejected on the centrifugal block assembly, so lubricated cooling is more even, has avoided wet clutch driving link 7 local superheatings.Because clutch chamber 3 and crankcase 1 are communicated with, the oil that enters clutch chamber from oil duct 6 returns crankcase 1 at last, and the final return engine fuel tank again of these lubricant oil, circulates, and constantly takes away heat, has kept centrifugal block assembly to be operated in normal temperature.
Oil circuit of the present invention is in proper order: oil pump pushes oilhole 8 and oil groove 6 in the sliding bearing into 5 with lubrication pressure, lubricated, cooling sliding bearing 5, lubricant oil is ejected on the clutch driving link 7 of clutch chamber 3 by gap between sliding bearing and the engine crankshaft then, clutch driving link 7 is lubricated cooling, lubricant oil in the clutch chamber 3 returns crankcase 1, lubricant oil in the crankcase 1 can carry out splash lubrication to in-engine miscellaneous part by the rotation of engine crankshaft 4, and the final return engine crankcase 1 again of these lubricant oil, circulate.
Claims (3)
1. crankcase mechanism with wet-type centrifugal clutch, comprise crankcase, centrifugal clutch, described centrifugal clutch comprises clutch chamber, it is characterized in that: described centrifugal clutch is arranged on a side of crankcase, the driving link of this centrifugal clutch and the pto of engine crankshaft are connected, and this clutch is a Wet-type centrifugal formula clutch, the pto of described engine crankshaft and crankcase joint are provided with sliding bearing, and the oil duct at sliding bearing place is communicated with pressure oil-source and clutch chamber.
2. the crankcase mechanism of band wet-type centrifugal clutch according to claim 1, described oil duct comprises from pressure oil-source and enters the oil duct of sliding bearing and flow to oil duct two-part of clutch chamber from sliding bearing, wherein the oil duct that enters sliding bearing from pressure oil-source is oilhole and the oil groove of offering at sliding bearing, and the oil duct that flows to clutch chamber from sliding bearing is to be made of gap between sliding bearing and the engine crankshaft.
3. the crankcase mechanism of band wet-type centrifugal clutch according to claim 1 and 2 is characterized in that described Wet-type centrifugal formula clutch driving link fixedly is connected with the clutch end of engine crankshaft is coaxial.
