Description
Technical field
The utility model relates to the motorcycle gearshift, especially relates to the automatic engaging mechanism of gear that uses in a kind of motorcycle gearshift.
Background technique
The motorcycle gearshift is the vitals of motorcycle transmission of power, its guarantee motorcycle can starting, gear shift and parking; The common gearshift of motorcycle engine mainly comprises selector fork, retaining dial axis, shifting cam, star-likely takes turns, gear level assembly, many parts such as gear assembly that gear is formed.During gearshift, by manual driven gear level assembly, the gear level assembly is stirred star-like the wheel, and star-like the wheel drives shifting cam, shifting cam drive selector fork, and selector fork is stirred movably gear, and then realizes adopting different right gears to carry out transmission, realizes shifting gears.In the shift process because the rotating speed of gear is very high, therefore when gearshift in conjunction with the time, be easy to bump.As time goes on, engine gear wearing and tearing aggravation meeting breaks down very soon.In order improving the working life of gear, normally to have improved the heat treatment requirements of gear surface at present, thereby manufacture cost to be strengthened.
Therefore the claimant considers, if can design a kind of mechanism that can realize that gear and rotating shaft are meshed automatically, then need not handsetting gear and can realize gearshift, can streamline organizations, and reduces cost, and reduces gear wear, prolongs gear life.
The model utility content
At above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is, provides a kind of and can realize gear and the automatic engaging mechanism of the automatic meshed gears of rotating shaft, reaches to reduce brinelling, improves gear life, improves the purpose of automaticity.
In order to solve the problems of the technologies described above, adopted following technological scheme in the utility model:
The automatic engaging mechanism of a kind of gear comprises rotating shaft and gear, and its characteristics are also to comprise
Cam, described cam are disk-like structure, and cam is fixedly sleeved in rotating shaft, and the cam periphery evenly is provided with several groove profile, and a side of cam is provided with mounting groove, be provided with the hoof piece in the mounting groove rotating shaft is installed;
Hoof piece, described hoof piece are positioned at mounting groove and for long strip, hoof piece one end is installed in rotation on the hoof piece and installs in the rotating shaft, deviates from the cylinder that a side of cam has a projection on the hoof piece the other end;
Torsion spring, described torsion spring is arranged in the mounting groove of cam, is connected in to apply between hoof piece and the hoof piece installation rotating shaft and to the hoof piece to make the hoof piece the other end be positioned at the torsion of locating near the cam axle center;
The engagement controller, described engagement controller is disk-like structure and is set in the rotating shaft side by side with described cam, an engagement controller side adjacent with cam is evenly distributed with several arc convex sections along periphery, arc convex hop count amount is consistent with the groove profile quantity of cam, it is adjacent with the engagement controller that described cam is positioned at arc convex section integrally formed annulus inside and cam mounting groove one side, also be provided with on the engagement controller side one with the hoof piece on the chute that mates of cylinder, cylinder one end on the described hoof piece is positioned at described chute;
Joggle post, described joggle post and shaft parallel setting and in engagement on the controller between the adjacent arc convex section, described joggle post leans on the groove profile of cam periphery mutually near axle center one end; Described geared sleeve is located at outside the engagement controller, torsion spring torsion that cylinder at one end can overcome under centrifugal action is to swinging away from place, cam axle center on the described hoof piece, and then make on the hoof piece cylinder to slide along the chute on the engagement controller and promote the rotation of engagement controller, make arc convex section on the engagement controller promote joggle post and move and push against between cam groove profile and inner ring gear along the cam groove profile.
As optimization, described mounting groove is provided with two and be symmetricly set on the flank of cam.Like this can be so that application of force balance makes clutch more reliable.
In the technical program, when described rotating shaft rotating speed is low, be separated state between rotating shaft and the gear, not driven gear rotation is rotated in rotating shaft this moment.When the rotating shaft rotating speed reaches certain speed, torsion spring torsion that cylinder at one end can overcome under centrifugal action is to swinging away from place, cam axle center on the described hoof piece, and then make on the hoof piece cylinder to slide and promote the rotation of engagement controller along the chute on the engagement controller, make the arc convex section promotion joggle post on the engagement controller move and push against between cam groove profile and inner ring gear along the cam groove profile, the realization rotating shaft combines with gear.The torque of rotating shaft this moment can be delivered on the gear by cam and joggle post, and driven gear rotates together.
When structure applications of the present utility model in being in the gearshift of the kind of drive with the gear engagement, just can realize self-shifting function, when specifically being provided with, the structure of this self shifter mechanism is, comprise power input shaft and pto, between power input shaft (being connected) and pto (being connected), some groups of pitch wheel groups are set earlier with rotation shaft of wheel with motor, the corresponding gear of every group of gear train (can comprise many to meshed gears) in succession, each gear train comprises that one is connected input gear on the power input shaft and one by this automatic clutch mechanism and is connected output gear on the pto by unidirectional driver, (unidirectional driver can adopt existing products in the prior art, and it act as and the torque unidirectional delivery of gear can not can be delivered to gear with the torque of output shaft in the same way to output shaft).Like this, only need corresponding each gear of automatic clutch mechanism in each group gear train to be set to different clutch rotating speed (this clutch rotating speed size is relevant with factors such as hoof piece quality and torsion spring torque magnitude and chute angles of inclination), can realize the self shifter of vehicle.
In sum, than prior art, the utility model possesses following advantage:
1,, can realize the automatic clutch between the motorcycle-gear, self shifter based on this mechanism.Improved automaticity.
2, this structure can superpose, and realizes that many gears control automatically.
3, the gear impact is little, the working life of effectively improving gear.
4, this mechanism also has when the rotating shaft rotating speed and does not mesh between hour rotating shaft and the gear, gear can rotate and reverse by the phase countershaft, rotating shaft and gear engagement also can drive the function of its rotation when the rotating shaft rotating speed reaches certain value, so in can also driving mechanism with some specific (special) requirements, such as requiring the output power at the very start can not be too small, and input power be this situation of process of an ascending gradual change.
