Description
Technical field
The utility model relates to motor, especially a kind of clutch control mechanism that is used for motorcycle engine.
Background technique
At present, the motorcycle engine of manually-operable clutch, because its clutch mechanism has the large-size integrating error, there is axial float in the axle that clutch is installed, make to occur big gap between engine clutch and the operating mechanism or not have the gap holding out against, when operation, occur easily separating thoroughly or the cltuch slipping situation.Even on control arm, increase stroke control mechanism, but limited because of its regulation range, still may make clutch take off not open or be in all the time half disengaged condition, not thorough or cltuch slipping phenomenon occur separating, thereby Security is relatively poor.
The model utility content
The purpose of this utility model provides a kind of axial float that can eliminate clutch, improves the clutch of motorcycle control mechanism of its Security.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: the left end of the described control mechanism of A. has the camshaft that is installed in the camshaft case, this camshaft lower end is provided with cam, torsion spring is equipped with in its upper end, there is the spring lacing wire outer end of torsion spring, and the right-hand member of this spring lacing wire is equipped with handle, on the center line of its left end flange is arranged, positioning block on this flange and the camshaft case outer wall matches, and positioning block is parallel with the center line of spring lacing wire with the contacted inclined-plane of flange; B., long push rod is housed in the gear-box spindle hole, and the left end of this long push rod is equipped with the spiral push rod, and its right-hand member is equipped with screw axis; C. on screw axis right-hand the screw putter that is installed in clutch gland inboard is arranged, the short push rod of spiral is housed on screw putter, the short push rod of this spiral contacts with the screw axis exterior edge face through steel ball; Locking plate is equipped with in the outside at the clutch gland, and locking nut is equipped with in the outside of this locking plate; D. the shaft axis of the shaft axis of described camshaft and long push rod is perpendicular, and cam and spiral push rod exterior edge face are for often to contact; The center line of E. described spring lacing wire has angle α with the parallel lines of the shaft axis of long push rod.
During installation, because the parallel lines of the shaft axis of the center line of spring lacing wire and long push rod have default angle, the positioning block on the camshaft case outer wall is parallel with the center line of spring lacing wire with the contacted inclined-plane of flange, and camshaft is quick and precisely located.Simultaneously, steel ball has the radial regulation effect, makes thrust all the time along the direction of axis line of short push rod of spiral and screw putter, guarantee clutch to neutrality.Be embedded in the polygonal hole that clutch gland center and its profile match with polygonal internal thread locking plate, the internal thread on it and the outside thread of screw putter match, when regulating the gap, when the restriction clutch rotates, the rotation screw putter, make the polygonal locking plate hold out against the clutch gland by the screw thread transmission, thereby realize the controllable adjustment of clutch play.At clutch closed state, by the axial distance of adjusting screw putter, and the clutch spring effect, the spiral push rod is pushed down cam, make between cam and the spiral push rod end face and be always the zero clearance, when operation, can effectively control the clutch stroke, further eliminated the axial float of clutch.
Remarkable result of the present utility model is: clutch alignment is good, both can prevent the clutch axial float, can prevent that again clutch from rotating positional accuracy height, reliable operation, safety.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a structural drawing of the present utility model.
Fig. 2 is that the A of Fig. 1 is to rotation diagram.
Fig. 3 is that the B of Fig. 2 is to rotation diagram.
Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, the utility model mainly by the short push rod 6 of clutch 19, camshaft 1, camshaft case 18, torsion spring 14, handle 11, spiral push rod 2, long push rod 3, screw axis 4, steel ball 5, spiral, screw putter 7, locking nut 8, locking plate 9 form.Annexation and structure outline between them are: the left end of the described control mechanism of A. has the camshaft 1 that is installed in the camshaft case 18, this camshaft 1 lower end is provided with cam 15, torsion spring 14 is equipped with in its upper end, there is spring lacing wire 10 outer end of torsion spring 14, the right-hand member of this spring lacing wire 10 is equipped with handle 11, flange 12 is arranged on the center line of its left end, positioning block 13 on this flange 12 and the camshaft case outer wall matches, and positioning block 13 is parallel with the center line of spring lacing wire 10 with flange 12 contacted inclined-planes; B., long push rod 3 is housed in the gear-box spindle hole, and the left end of this long push rod 3 is equipped with spiral push rod 2, and its right-hand member is equipped with screw axis 4; C. on screw axis 4 right-hand the screw putter 7 that is installed in clutch gland 16 inboards is arranged, the short push rod 6 of spiral is housed on screw putter 7, the short push rod 6 of this spiral contacts with screw axis 4 exterior edge faces through steel ball 5; In the outside of clutch gland 16 locking plate 9 is housed, locking nut 8 is equipped with in the outside of this locking plate 9; The shaft axis of the shaft axis of D. described camshaft 1 and long push rod 3 is perpendicular, and cam 15 and spiral push rod 2 exterior edge faces are for often to contact; The center line of E. described spring lacing wire 10 has angle α with the parallel lines of the shaft axis of long push rod 3.
In the present embodiment, according to different motorcycle engine models, the 15 °≤α of angle of the parallel lines of the shaft axis of the center line of described spring lacing wire 10 and long push rod 3≤90 °.Angle α is generally 15～30 degree.The spiral chute on the short push rod of spiral push rod 2, screw axis 4 and spiral 6 surfaces can improve the mistake oiliness of lubricant oil in the spindle hole, improves lubrication effect.Because the short push rod 6 of described screw axis 4 and spiral is a sphere with steel ball 5 contacted end faces, so steel ball 5 has the radial regulation effect, makes thrust all the time along the direction of axis line of short push rod 6 of spiral and screw putter 7, guarantee clutch 19 to neutrality.The left end of spiral push rod 2 is generally cylindrical, and its middle part is the spiral cylindricality, and right-hand member is a screw rod.Polygonal internal thread is with in being shaped as of locking plate 9, and this locking plate 9 is embedded in the polygonal hole that clutch gland 16 centers and its profile match, and the outside thread of internal thread on it and screw putter 7 matches.Generally speaking, locking plate 9 is a Hexagon for polygonal, and the outside thread of internal thread on it and screw putter 7 matches, and can prevent clutch with respect to the screw putter axial float, and its polygonal outer shape can prevent that clutch from rotating, and guaranteed the positional accuracy of clutch.
During installation, because the shaft axis of the center line of spring lacing wire 10 and long push rod 3 has default angle α, the positioning block 13 on camshaft case 18 outer walls is parallel with the center line of spring lacing wire with flange 12 contacted inclined-planes, and camshaft 1 is quick and precisely located.Simultaneously, at clutch 19 closed states, by the axial distance of adjusting screw putter 7, and clutch spring 17 effects, spiral push rod 2 is pushed down cam 15, make between cam 15 and spiral push rod 2 end faces and be always the zero clearance.
During operation, move handle 11 counter clockwise, camshaft 1 rotation, cam 15 pushes up spiral push rod 2 to the right, drives screw putter 7 and moves right, and clutch 19 breaks away from; Clockwise direction is moved handle 11, and the pressure of clutch spring 17 makes clutch 19 closures, by gland 16 screw putter 7, the short push rod 6 of spiral, steel ball 5, long push rod 3, spiral push rod 2 is pressed left simultaneously.Because between cam 15 and spiral push rod 2 end faces is the zero clearance, effectively the solenoidoperated cluthes stroke is avoided the clutch axial float.
