Description
Technical field
The utility model relates to a kind of centrifugal Oil saving semi shaft device.
Background technology
In the prior art, automobile fuel-saving half shaft utilizes the mechanical movement principle design, on the circular chuck of automobile spindle nose spline tooth upper end, be provided with a plurality of latch seat grooves, this latch seat groove inboard is provided with cylindrical spring, when automobile slide, under a plurality of cylindrical spring effects, the disengaging that interlaces of convex shape on convex body on the clutch discs and the latch disk body, latch is covered in the latch seat groove, the spindle nose with spline tooth is separated with housing, realize sliding purpose; When running car, two convex shapes are collided, and under mutual thrust, latch and clutch discs are left, and latch snaps in the latch groove of housing, realizes the purpose of transmission output.This technical pattern complexity, spring is easily fractureed by the key tooth, so fault rate is higher, and oil-saving effect is poor, and service life is low.
The utility model content
The purpose of this utility model is to improve the shortcoming of prior art, a kind of centrifugal Oil saving semi shaft device is provided, it is the principle of inertia that adopts rotary mechanics, according to the needs that travel or slide, automatically change the variation of rotating speed and revolutional slip, realize good oil-saving effect, its fault rate is low, long service life.
For achieving the above object, the utility model is taked following design plan: it is provided with a centrifugal Oil saving semi shaft device case, this housing is provided with flange, and its housing top is provided with lid and gland, and is fixed together by check screw and gland seal ring and housing; Be provided with a bearing in the described housing, this bearing is set on the flange by inside and outside bayonet lock, be provided with ratchet coil tension spring and pawl pockets on the semiaxis in housing, be provided with left and right centrifugal block at semiaxis spindle nose end, stud with centrifugal block fix shaft in it, described centrifugal is provided with the flexible retainer spring of centrifugal block and should flexible retainer spring holding screw, is provided with semiaxis ratchet clutch sliding sleeve in the lid inboard and the ratchet clutch sliding sleeve is dialled slotting lever.When automobile driving speed did not need to slide, the technique device of this semiaxis was in the state of the art of former automobile; When automobile driving speed makes the rotating speed of semiaxis meet the requirements of design value, left and right centrifugal block in the self-con-tained unit of this semiaxis is under the force of inertia effect, making centrifugal block produce direction under the effect of fix shaft changes, left and right two centrifugal blocks are outer synchronously to be moved, flexible retainer spring is stretched by the force of inertia of left and right two centrifugal blocks, at this moment the ratchet clutch sliding sleeve that is located on the left and right centrifugal block is dialled slotting lever generation group slotting power, and the ratchet clutch sliding sleeve is cut by the ratchet in casing and the semiaxis hugging.When automobile driving speed makes the semiaxis rotating speed reach the design fuel-economizing value of sliding, the driver receives oil, automotive engine is in the low-speed motion state, at this moment the semiaxis velocity of rotation slows down, ratchet in the draw-in groove between semiaxis and housing combines stressed reducing, and when the face of ratchet clutch sliding sleeve suited power greater than the binding force difference of ratchet and semiaxis and housing, the ratchet in the pawl pockets was cut off by ratchet clutch sliding sleeve and housing, ratchet is rotated in the clutch sliding sleeve, and this moment, automobile was in sliding state.
When the coasting speed of automobile drops to design value, because the moving velocity of automobile reduces semiaxis rotating speed force of inertia, the force of inertia of the centrifugal block in the left and right sides also reduces thereupon, at this moment stretching between the centrifugal block in the left and right sides draw spring with about the inertia distance of two centrifugal blocks retract original position when being zero (be design-calculated inertia values), make the slotting lever of dialling of ratchet clutch sliding sleeve dial back original position, at this moment ratchet snaps in the pawl pockets under the thrust of ratchet spring, making semiaxis and housing card is one, realizes automobile normal operating condition (being that the robot control system(RCS) value of centrifugal Oil saving semi shaft returns to the state of the art in the standard of travelling of former automobile again).
The utility model is simple in structure, manufacturing, easy for installation, safe in utilization, and the life-span is long.

The specific embodiment
As shown in Figure 1 and Figure 2, the utility model is provided with centrifugal Oil saving semi shaft device case 1, and this housing 1 is provided with flange 1-1, and described housing 1 is provided with lid 2 and gland 3, and is fixed together with housing 1 by check screw 4 and gland seal ring 5; The semiaxis 11 of described housing 1 is provided with a bearing 6, this bearing 6 is set in the flange 1-1 by inside and outside bayonet lock 7,8, in housing 1, be provided with ratchet coil tension spring 9 and pawl pockets 10, be provided with left and right centrifugal block 12 in semiaxis 11 spindle nose terminations, stud with centrifugal block fix shaft 13 in it, described centrifugal block 12 is provided with the flexible retainer spring 14 of centrifugal block and the retainer spring holding screw 15 that should stretch, and is provided with semiaxis ratchet clutch sliding sleeve 16 and ratchet clutch sliding sleeve in lid 2 inboards and dials slotting lever 17.When automobile driving speed did not need to slide, the technique device of this semiaxis was in the state of the art of former automobile; When automobile driving speed makes the rotating speed of semiaxis meet the requirements of design value, left side in the self-con-tained unit of this semiaxis, right centrifugal block 12, under the effect of semiaxis rotating speed force of inertia, produce inertia, making centrifugal block 12 produce direction under the effect of fix shaft changes, a left side, right two outer synchronously moving of centrifugal block 12, make flexible retainer spring 14 by a left side, the force of inertia of right two centrifugal blocks stretches, at this moment be provided with a left side, ratchet clutch sliding sleeve on the right centrifugal block 12 is dialled the lever 17 generation group slotting power of inserting, this ratchet clutch sliding sleeve 16 is cut by the ratchet in housing 1 and the semiaxis hugging 18 19, when automobile driving speed makes the rotating speed of semiaxis reach the design fuel-economizing value of sliding, the driver receives oil, automotive engine is in the low-speed running state, at this moment semiaxis 11 velocities of rotation slow down, ratchet 19 in the pawl pockets 10 of semiaxis 11 and 1 of housing combines stressed reducing, when at this moment the face of ratchet clutch sliding sleeve 16 suits power greater than the binding force difference of ratchet 19 and semiaxis 11 and shell 1, ratchet 19 in the pawl pockets 10 is cut off with housing 1 by the centrifugal sliding sleeve 16 of ratchet, ratchet 19 is rotated in the clutch sliding sleeve, and this moment, automobile was in sliding state.
When the coasting speed of automobile drops to design value, because the moving velocity of automobile reduces semiaxis 11 rotating speed force of inertias, the force of inertia of left and right centrifugal block 12 also reduces thereupon, at this moment the flexible retainer spring 14 between the left and right centrifugal block 12 retracts original position (be design-calculated inertia values be zero time) with left and right two centrifugal blocks 12, the slotting lever 17 of dialling of ratchet clutch sliding sleeve arrives back original position, at this moment ratchet 19 snaps in the pawl pockets 10 under the thrust of ratchet coil tension spring 9, make semiaxis 11 and housing 1 card be one, realize the automobile normal operating condition.
