Embodiment
Be described technological scheme of the present invention below by way of specific embodiment, with under the conflict free prerequisite of goal of the invention of the present invention, the technical characteristics in the embodiment hereinafter mentioned and embodiment can combine mutually.
As Figure 1-Figure 4, the invention provides one and automatically resetly controlledly can get rid of block formula automatic clutch axle, 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 first radial direction through hole 11, first radial direction through hole 11 and center hole 10 UNICOM; On rotating shaft body 1, the second pre-position is equipped with the second radial direction through hole 12, second radial direction through hole 12 and center hole 10 UNICOM, and the two ends of center hole 10 are closed respectively by plug 101;
One cylinder component 2, is sheathed on rotating shaft body 1 and together rotates with rotating shaft body 1, and location matches first radial direction through hole 11;
Cylinder component 2 is provided with the cavity 21 of receiving fluids, and cavity 21 is provided with annular opening 211 and the first radial direction through hole 11 UNICOM;
The piston element 212 of an annular is provided with in cavity 21; The projection 213 that piston element 212 is provided with an annular stretches out cylinder component 2; Be provided with elastic element 22 between piston element 212 and cavity 21 inwall, reset in order to make piston element 212;
One gets rid of block formula clutch 4, be sheathed on the position of rotating shaft body 1 mating the second radial direction through hole 12, get rid of block formula clutch 4 to comprise at least two and get rid of block 41 and be connected on centrifugal pan 40 by the Returnning spring of a predetermined coefficient of stiffiness, also comprise and get rid of block control block 42, get rid of that block control block 42 is mobilizable to be connected on centrifugal pan 40 and to get rid of block 41 be connected with at least two, centrifugal pan 40 is provided with UNICOM second radial direction through hole 12 and the oil duct 401 getting rid of block control block 42, get rid of block control block 42 to shrink by forcing to get rid of block 41 in oil duct 401 during liquid-driving, get rid of not interfere when block control block 42 resets and get rid of block 41.
In technique scheme, the projection 213 of cylinder component 2 is stretched out by the piston element 212 promoted in the cavity 21 of cylinder component 2, and then drive piston element 212 to move in cavity 21, flow into the radial direction through hole 11 rotating shaft body 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 centrally hole 10 flows to the second radial direction through hole 21, and the oil duct 401 flowing into centrifugal pan 40 promotes to get rid of block control block 42, make to get rid of block 41 to shrink, thus be separated with clutch cover 44, clutch cover 44 is connected on rotating shaft body 1 by unilateral bearing.
Getting rid of block formula clutch is prior art, its working principle is, get rid of block 41 and be reset spring 43 banding (for clearly showing the action of getting rid of block in Fig. 3 and Fig. 4, therefore do not draw Returnning spring 43), and being connected on centrifugal pan 40, centrifugal pan 40 to be connected on rotating shaft body 1 and to rotate with rotating shaft body 1, gets rid of block 41 and be in contraction state when the rotating speed of centrifugal pan 40 does not reach predefined value under the effect of Returnning spring 43, therefore get rid of block 41 and do not contact clutch cover 44, clutch is in separated state.When the rotating speed of centrifugal pan 40 reaches preset rotation speed, under the influence of centrifugal force, get rid of the active force that block 41 overcomes Returnning spring 43 and outwards launch, contact clutch cover 44, makes clutch be in bonding state.The present invention gets rid of block control block 42 by increase hydraulic control, make to get rid of block 41 by extra control when making centrifugal pan 40 reach desired speed to force to shrink, thus realize the Non-follow control under automatic clutch working state, block 41 is got rid of owing to getting rid of not interfere when block control block 42 resets, therefore, when getting rid of block control block 42 and resetting, get rid of block 41 and return to again the symphyogenetic automatic clutch state of the centrifugal force accepting Returnning spring 43 and centrifugal pan 40.
In one preferably mode of execution, get rid of block control block 42 and elastic reset member 421 can be set.When the thrust acting on protruding 213 disappears, the elastic reset member 421 getting rid of block control block 42 makes to get rid of block control block 42 and resets, and then make liquid by oil duct 401, second radial direction through hole 12 is along the center hole 10 of rotating shaft body 1, first radial direction through hole 11, pass back in cavity 21 with the annular opening 211 of cylinder component 2, promote piston element 212 and reset to assist it.
In a kind of embodiment of the present invention, get rid of block 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 be separated with rotating shaft body 1, shift fork 3 mates with protruding 213, in order to promote protruding 213.Technological scheme of the present invention can apply an active force in shift fork 3 when implementing, and makes shift fork 3 promote protruding 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 groove 13 respectively, are embedded with O type ring 14 in groove 13 respectively, are sealed between cylinder component 2 and rotating shaft body 1 by O type ring 14.
The above embodiments are only that part of the present invention embodies; can not contain all of the present invention; on the basis of above-described embodiment and accompanying drawing; those skilled in the art can obtain more mode of execution under the prerequisite not paying creative work, and therefore these mode of executions obtained under not paying the prerequisite of creative work all should be included in protection scope of the present invention.
