Embodiment
By specific embodiment, technological scheme of the present invention is described below, with the conflict free prerequisite of goal of the invention of the present invention under, embodiment and the technical characteristics in embodiment hereinafter mentioned can combine mutually.
As shown in Figure 1-Figure 3, the invention provides a kind of automatically reset piece formula automatic clutch axle that gets rid of, wherein, comprising:
One rotating shaft body 1, rotating shaft body 1 is provided with center hole 10, and on rotating shaft body, precalculated position is equipped with a plurality of the first radial direction through hole 11, the first radial direction through hole 11 and center hole 10 UNICOMs; On rotating shaft body 1, the second pre-position is equipped with the second radial direction through hole 12, the second radial direction through hole 12 and center hole 10 UNICOMs, and the two ends of center hole 10 are sealed by plug 101 respectively;
One cylinder component 2, is sheathed on rotating shaft body 1 and together rotates with rotating shaft body 1, and location matches the first radial direction through hole 11;
In cavity 21, be provided with the piston element 212 of an annular; Piston element 212 is provided with the projection 213 of an annular and stretches out cylinder component 2; Between piston element 212 and cavity 21 inwalls, be provided with elastic element 22, use so that piston element 212 resets.
One gets rid of piece formula clutch 4, be sheathed on the position of mating the second radial direction through hole 12 on rotating shaft body 1, get rid of piece formula clutch 4 and comprise that at least two are got rid of the Returnning spring of piece 41 by a predetermined coefficient of stiffiness and are connected on centrifugal pan 40, also comprise and get rid of piece control block 42, get rid of that piece control block 42 is mobilizable to be connected on centrifugal pan 40 and to get rid of piece 41 and be connected with at least two, centrifugal pan 40 is provided with UNICOM's the second radial direction through hole 12 and gets rid of the oil duct 401 of piece control block 42, get rid of and when piece control block 42 is subject in oil duct 401 liquid-driving, force to get rid of piece 41 and launch, get rid of when piece control block 42 resets and do not interfere and get rid of piece 41.
In technique scheme, the projection 213 that can stretch out cylinder component 2 by the piston element 212 in the cavity 21 of promotion cylinder component 2, and then drive piston element 212 to the interior movement of cavity 21, the radial direction through hole 11 flowing into rotating shaft bodies 1 from annular opening 211 after liquid in cavity 21 is extruded, and then flow in the center hole 10 of rotating shaft body 1, and flow to the second radial direction through hole 21 along center hole 10, and the oil duct 401 that flows into centrifugal pan 40 promotes to get rid of piece control block 42, make to get rid of piece 41 and launch contact clutch cover 44, clutch cover 44 is connected on rotating shaft body 1 by unilateral bearing.
Getting rid of piece formula clutch is prior art, its working principle is, get rid of piece 41 be reset spring 43 bandings (in Fig. 3 for clearly performance get rid of piece action, therefore do not draw Returnning spring 43), and be connected on centrifugal pan 40, centrifugal pan 40 is connected on rotating shaft body 1 and rotates with rotating shaft body 1, the rotating speed of centrifugal pan 40 while not reaching predefined value, get rid of piece 41 under the effect of Returnning spring 43 in contraction state, therefore getting rid of piece 41 does not contact clutch cover 44, and clutch is in separated state.When the rotating speed of centrifugal pan 40 reaches preset rotation speed, under the effect of centrifugal force, get rid of the active force that piece 41 overcomes Returnning spring 43 and outwards launch, contact clutch cover 44, makes clutch in bonding state.The present invention gets rid of piece control block 42 by what increase hydraulic control, while making centrifugal pan 40 not reach desired speed, can by extra control, make to get rid of piece 41 opens in advance, owing to getting rid of when piece control block 42 resets, do not interfere and get rid of piece 41, therefore when getting rid of 42 reset of piece control block, get rid of piece 41 and return to again the symphyogenetic automatic clutch state of centrifugal force of accepting Returnning spring 43 and centrifugal pan 40.
One, preferably in mode of execution, get rid of piece control block 42 elastic reset member 421 can be set.When acting on the thrust disappearance of projection 213, the elastic reset member 421 that gets rid of piece control block 42 makes to get rid of piece control block 42 and resets, and then make liquid by oil duct 401, the second radial direction through hole 12 is along the center hole 10 of rotating shaft body 1, the first radial direction through hole 11, pass back in cavity 21 with the annular opening 211 of cylinder component 2, promote piston element 212 to assist its reset.
In a kind of embodiment of the present invention, get rid of piece 41 and can arrange 2-4.
In a kind of embodiment of the present invention, the liquid in cavity 21 can be hydraulic oil.
In a kind of embodiment of the present invention, also comprise a shift fork 3 separated with rotating shaft body 1, shift fork 3 mates with projection 213, in order to promote projection 213.Technological scheme of the present invention can apply an active force in shift fork 3 while implementing, and makes shift fork 3 promote projection 213, and then promotes piston element 212.
In a kind of embodiment of the present invention, the first radial direction through hole 11 both sides are equipped with respectively groove 13, and the interior O type ring 14 that is embedded with respectively of groove 13 seals by O type ring 14 between cylinder component 2 and rotating shaft body 1.
The above embodiments are only that part of the present invention embodies; can not contain of the present invention whole; on the basis of above-described embodiment and accompanying drawing; those skilled in the art can obtain more mode of execution under the prerequisite of not paying creative work, so these are not paid the mode of execution obtaining under the prerequisite of creative work and all should be included in protection scope of the present invention.
