Embodiment
Fig. 1 is to shown in Figure 6, be the non-road automobile of the utility model one-way clutch formula stepless speed changes devices specific embodiments, it comprises the drive wheel assemblies 1 that is arranged on the input shaft 2, be arranged on the follower assembly 4 on the output shaft 5, drive wheel assemblies 1 is connected with follower assembly 4 by belt 3, described drive wheel assemblies 1 comprises belt pulley 6, wheel shaft 13, sliding sleeve 7, spring seat 8, guide pulley 9, driving wheel spring 11, supporting wheel 10, belt pulley 6 is fixed on the wheel shaft 13, sliding sleeve 7, spring seat 8, guide pulley 9 is movably set on the wheel shaft 13 and by supporting wheel 10 axially locating successively, sliding sleeve 7 is arranged on the sliding sleeve fitting surface 17 of wheel shaft 13, spring seat 8 is arranged on the spring seat fitting surface 18 of wheel shaft 13, driving wheel spring 11 is arranged between spring seat 8 and the guide pulley 9, sliding sleeve 7 and spring seat 8 can move axially and rotate on wheel shaft 13, and guide pulley 9 can move axially on wheel shaft 13.Bearing 19 is equipped with in described sliding sleeve 7 both sides, the outer surface of sliding sleeve 7 is provided with and promotes inclined-plane 20, its internal surface is provided with two groups at least along the equally distributed spiral chute 22 of axis, between two spiral chutes by 21 transition of spirally-guided face, spiral chute 22 and the axis β that has a certain degree, at least be provided with two pin shaft holes on the wheel shaft 13, be provided with the bearing pin spring 14 and the bearing pin 15 of retractable in the pin shaft hole, the spiral chute 22 of the end face of bearing pin 15 and sliding sleeve 7 is inconsistent.At least be provided with three uniform support arms 23 on the described supporting wheel 10, correspondence is provided with rotating ball 12 on the support arm 23, be hinged with on the guide pulley 9 and the ball 12 contacted pieces 11 that get rid of, get rid of in the guide groove 27 that piece 11 is limited in support arm 23, guide pulley 9 can only be moved axially.
Working principle of the present utility model is as follows: before the startup, belt 3 inner surface layers are overlapped on the slide bushing assembly 7, there is gap 24 between the stationary plane 16 of belt 3 and belt pulley 6, there is gap 25 between the promotion face 28 of belt 3 and guide pulley 9, after the engine start, belt pulley 6 rotates with idling under input shaft 2 drives, bearing pin 5 end faces that rotate on the wheel shaft 13 this moment are crossed spirally-guided face 21 after a spiral chute 22 slips over, slide into again on another spiral chute 22, so alternately slide on spiral chute 22 and spirally-guided face 21, does not rotate sliding sleeve 7 outer rings, and belt 3 and follower assembly 4 do not rotate, realize starting clutch, as shown in Figure 7.
Along with engine speed raises, the piece 11 that gets rid of on the guide pulley 9 promotes ball 12 on the supporting wheel 10 under action of centrifugal force, because supporting wheel 10 is fixed on the input shaft 2 with wheel shaft 13, guide pulley 9 wheel shaft 13 relatively moves axially, guide pulley 9 promotes belts 3 and moves right getting rid of under piece 11 effect its promotion face 28, and be pressed on the stationary plane 16 of belt pulley 6, belt 3 begins to rotate transferring power; Along with engine speed constantly raises, the Driving force that belt 3 is subjected to guide pulley 9 constantly increases, make the internal layer of belt 3 leave sliding sleeve 7 outer surfaces, between sliding sleeve 7 outer surfaces and belt 3 internal surfaces, form gap 26, and the gap constantly increases, change to minimum up to gear ratio by maximum, thereby realize stepless change, as shown in Figure 8.
When engine retard or descending, the speed that follower assembly 4 rotates is greater than the speed of input shaft 2, belt 3 acts on sliding sleeve 7 outer rings, make sliding sleeve 7 counterrotatings, the bearing pin 15 that rotates together with wheel shaft 13 acts on the spirally-guided face 21 of sliding sleeve 7 and promotes sliding sleeve 7 and moves to the left, belt 3 promotes under face 20 effects at sliding sleeve, make belt 3 be pressed on the effect of playing braking on the promotion face 28 on the guide pulley 9, make follower assembly 4 rotational velocity of this moment be reduced to consistent with engine idle, thereby realize slowing down or down hill braking, as shown in Figure 9.
