Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the invention is elaborated.
As shown in Fig. 3～5, this integrated form slide block mechanism, comprises pushing block 1, locating piece 2, spring 3 andSteel ball 4, the bottom surface that the bottom of pushing block 1 offers the first horizontal through hole 9, the first through holes 9 is planeAnd the center of bottom surface is provided with the locating hole 6 for stationary positioned piece 2, locating piece 2 is placed in first and leads toIn hole 9, the cross section of locating piece 2 is that T-shape and its underpart are embedded in locating hole 6.
The central axis on pushing block 1 top is provided with the second vertical through hole 5 connecting with the first through hole 9,The diameter of the aperture of the second through hole and spring 3 and steel ball 4 matches, and the lower end of spring 3 is logical through secondHole 5 and be butted on the end face of locating piece 2, the upper end of spring 3 peaks at the upper of the bottom of steel ball 4 and steel ball 4Portion exposes to the second through hole 5, and the flexible drive steel ball 4 of spring 3 moves up and down in the second through hole 5.
The end face of pushing block 1 is provided with the guiding spline 7 that is positioned at steel ball 4 left and right sides, pushing block 1 topDescribed joint portion on the sidewall of left and right, is provided with the joint portion of horizontal evagination, as long as can be stuck in tooth hub by pushing block 1Pushing block groove in, anti-thrust block 1 is radially outward deviate from along tooth hub, the reality that the invention providesExecuting example is: joint portion be set to be arranged above and below and with wide two the square strip projected parts 8 of pushing block 1.
Synchronized as shown in Figure 6, comprise tooth hub, be set in tooth hub periphery tooth cover, be arranged at tooth hubLock ring and the integrated form slide block mechanism as claimed in claim 1 of both sides, front and back, the excircle of described tooth hubTo being evenly equipped with the pushing block groove matching with described pushing block 1, on the inwall on described pushing block groove top, be provided withThe draw-in groove that joint portion on described pushing block 1 matches, is evenly equipped with described on the inner peripheral surface of described tooth coverThe locating slot that steel ball 4 matches, pushing block 1 can slide in the pushing block groove on tooth hub along draw-in groove.
Spring 3 withstands steel ball 4 makes it expose to the second through hole 5 and the top end face higher than guiding spline 7,Cause tooth cover and tooth hub to depart from if other parts of synchronized assembly are damaged, the elastic force of spring 3 onlySteel ball 4 may be ejected, itself and locating piece 2 are still integrated in pushing block 1, can not occurBe scattered, reduced the difficulty of ressembling.
As shown in Figure 3, in order to adapt to the synchronized of different sizes, in order to coordinate the tooth hub of different-diameter,The top of locating piece 2 is set to cylindric, and the height of the thickness at its top and pushing block 1 adapts. NoThe pushing block 1 that need select differing heights with the tooth hub of diameter, in the situation that not changing other parts, passes throughChange the different locating piece 2 of top thickness and can ensure the active force of spring 3 to steel ball 4.
As shown in Figure 5, in order better to avoid spring 3 to bend, ensure that it stretches in extrusion processContracting power is along the central axis direction of pushing block 1, and the center of the end face of locating piece 2 is provided with determining to upper processPosition axle 21, locating shaft 21 plugs the inner chamber into spring 3 from the lower end of spring 3.
When assembling, locating piece 2 is put into the locating hole 6 of pushing block 1 by the first through hole 9, spring 3 fromThe top of the second through hole 5 packs into, the lower end of spring 3 is contacted, then by steel with the end face of locating piece 2Ball 4 is put into the port of spring 3 upper ends, then the joint portion of the both sides of pushing block 1 is stuck on tooth hubIn draw-in groove, finally assemble tooth cover. Spring 3 and steel ball 4 are integrated in the second through hole 5 of pushing block 1, push awayPiece 1 is positioned in the pushing block groove of synchromesh gear hub, and under the effect of spring 3, steel ball 4 upwards embeds tooth coverIn the corresponding locating slot of inner ring, play neutral positioning action, when gearshift, the guiding spline 7 on pushing block 1Limit tooth cover and promote the axially-movable of pushing block 1 along synchronized, before and after pushing block 1 front/rear end snaps in tooth hubIn breach on the lock ring of side time, complete gearshift.
Above the invention embodiment is had been described in detail, but described content is only thisThe preferred embodiment of bright creation, can not be considered to the practical range for limiting the invention. Fan YibenEqualization variation and improvement etc. that innovation and creation application range is done, all should still belong to the special of the inventionWithin profit covering scope.
