Abstract
The invention discloses a motorbike engine crank shaft mechanism with a CVT continuously variable transmission system, which is characterized in that an engine crank shaft is sleeved in the left and the right crank shaft boxes of the engine; the left side of the engine crank shaft is sleeved with a centrifugal block component of a centrifugal clutch, a locking nut, while the right side is sleeved with a gas distribution chain, a rotor component of a magnetor and a nut; wherein the centrifugal block component, the locking nut , the rotor component of the magnetor and the nut operate with the engine crank shaft synchronously; the centrifugal block component is sleeved with a follower combination of the clutch which is in linkage with a CVT driving wheel component; the outside of the right crank shaft box is assembled with a right crank shaft box cover, and an engine regulation hole is arranged at the center of the engine crank shaft of the right crank shaft box cover and is sleeved with a sealing ring and an adjusting hole plug. The motorbike engine crank shaft mechanism provides convenience for the assembly and maintenance of the motorbike engine with the CVT continuously variable transmission system.
Description
Technical field
The present invention relates to a kind of band CVT stepless speed variator system mechanism for rotating crankshaft of motorcycle engine.
Background technique
Existing band CVT stepless speed variator system motorcycle engine transmission system all adopts the dry type automatic centrifugal clutch, and CVT follower assembly and clutch pack integral body place on the motor rear propeller shaft; Therefore motor assembles, debugs, when maintenance needs the rolling motor bent axle, all adopts the left crankcase that takes apart the engine to cover the method for rolling motor bent axle left part.Said method is inconvenient operation on the one hand, and workload is big; On the other hand, the automatic centrifugal clutch in the motorcycle engine transmission system can only place on the motor rear propeller shaft, can not place on the engine crankshaft, so because of the reason of CVT transmission gear shift, has reduced the reliability of automatic centrifugal clutch work.
Summary of the invention
The object of the invention is to overcome the deficiency of existing technology; Provide a kind of power train to adopt Wet-type centrifugal formula clutch, place the assembling of band CVT stepless speed variator system motorcycle engine, debugging of engine crankshaft left part, a kind of novel mechanism of rolling motor bent axle when maintenance needs the rolling motor bent axle.
For addressing the above problem, the present invention adopts following technological scheme:
Technological scheme of the present invention is: a kind of band CVT stepless speed variator system mechanism for rotating crankshaft of motorcycle engine, and it comprises motor left crankcase, right crankcase, engine crankshaft, described engine crankshaft is set on the left and right crankcase of motor; The engine crankshaft left side is set with the centrifugal block assembly of centrifugal clutch, locking nut, and centrifugal block assembly of centrifugal clutch and engine crankshaft are connected, and the right side is set with distribution chain, magneto rotor assembly, nut; Described centrifugal block assembly, locking nut and magneto rotor assembly, nut and engine crankshaft run-in synchronism; The centrifugal block assembly periphery of said centrifugal clutch is set with the combination of clutch driven member, is set with the CVT drive wheel assemblies in the said clutch driven member combination, and said CVT drive wheel assemblies and the combination of clutch driven member are connected; The said motor left crankcase outside is equipped with the left crankcase lid, and the engine right crankcase outside is equipped with right crankcase cover.
The present invention further is set to: the engine crankshaft center of described right crankcase cover is provided with the motor adjustment hole, and its parallel axes is set with seal ring, regulates stopple in the engine crankshaft center line on the described motor adjustment hole;
Compared with prior art; The invention has the beneficial effects as follows: motor assembling, debugging, when maintenance needs the rolling motor bent axle, only need pull down the adjusting stopple on the right crankcase cover adjustment hole, the adjustment hole that covers through right crankcase; The nut on rolling motor bent axle right side; Reach the purpose of rolling motor bent axle, compared with prior art, easy and simple to handle;
Further beneficial effect of the present invention is: provide a kind of power train to adopt Wet-type centrifugal formula clutch; Place the band CVT stepless speed variator system motorcycle engine assembling, debugging of engine crankshaft left part, a kind of novel mechanism of rolling motor bent axle when maintenance needs the rolling motor bent axle; Because of the engine crankshaft left part is set with Wet-type centrifugal formula clutch; Motor all is in off working state when assembling, debugging, maintenance; Clutch is in non-binding state, utilizes existing technology can not reach the purpose of rolling motor bent axle.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1: a kind of band of the present invention CVT stepless speed variator system mechanism for rotating crankshaft of motorcycle engine, it comprises motor left crankcase 1, right crankcase 2, engine crankshaft 3, described engine crankshaft is set on the left and right crankcase of motor; Engine crankshaft left side is set with the centrifugal block assembly of centrifugal clutch 4, locking nut 5, and centrifugal block assembly of centrifugal clutch and engine crankshaft are connected, and the right side is set with distribution chain 6, magneto rotor assembly 7, nut 8; Described centrifugal block assembly, locking nut and magneto rotor assembly, nut and engine crankshaft run-in synchronism; The centrifugal block assembly periphery of said centrifugal clutch is set with clutch driven member combination 9, is set with CVT drive wheel assemblies 10 in the said clutch driven member combination, and said CVT drive wheel assemblies and the combination of clutch driven member are connected; The said motor left crankcase outside is equipped with left crankcase lid 11, and the engine right crankcase outside is equipped with right crankcase cover 12; The engine crankshaft center of described right crankcase cover is provided with motor adjustment hole 13, and its parallel axes is set with seal ring 14, regulates stopple 15 in the engine crankshaft center line on the described motor adjustment hole; Motor assembles, debugs, keeps in repair when needing the rolling motor bent axle; Only need pull down seal ring, adjusting stopple on the right crankcase cover adjustment hole; Through the adjustment hole that right crankcase covers, the nut on rolling motor bent axle right side reaches the purpose of rolling motor bent axle; Compared with prior art, easy and simple to handle; Because of the engine crankshaft left part is set with Wet-type centrifugal formula clutch, motor all is in off working state when assembling, debugging, maintenance, and Wet-type centrifugal formula clutch is in non-binding state, utilizes existing technology can not reach the purpose of rolling motor bent axle; The present invention provides a kind of power train to adopt Wet-type centrifugal formula clutch; Place the band CVT stepless speed variator system motorcycle engine assembling, debugging of engine crankshaft left part, a kind of novel mechanism of rolling motor bent axle when maintenance needs the rolling motor bent axle; Simple in structure, easy to operate.
The present invention is not limited to above-mentioned preferred forms, and anyone other any improvement that under enlightenment of the present invention, draws is all within protection scope of the present invention.
