Detailed description of the invention
Embodiment one:
The present embodiment be a kind of limit axial force under the torque transmitter that can disconnect, as Figure 1-3.The present embodiment comprises: imput shaft 1 and driven axle 10, and described imput shaft is fixedly connected with initiatively inclined tab 2, described active inclined tab is fixedly connected with initiatively plain film 8.Described active plain film is provided with two and initiatively dials bolt 3, initiatively dial bolt through the flexible connecting member 7 be mounted on active plain film for described two, and stir the two ends of shifting fork piece 4 respectively, described shifting fork piece and described flexible connecting member are clipped in initiatively between plain film and passive plain film 6, described passive plain film is provided with two passive group of bolts 5 through described flexible connecting member, described passive plain film is fixedly connected with passive inclined tab 9, and described passive inclined tab is fixedly connected with described driven axle.
For clearly expressing the spatial relationship of the present embodiment, with Fig. 1, the relation between axis between each key element and axis place plane is described.In the present embodiment, the central axis 101 of two axis initiatively dialling bolt and imput shaft is coplanar, and the present embodiment claims this plane for " active plane 13 " (representing with long and two-short dash line in Fig. 1).It is coplanar that two velamens move the central axis 1001 dialling bolt and driven axle, and the present embodiment claims this plane for " passive plane 11 " (representing with long and two-short dash line in Fig. 1).Initiatively the central axis 12 of inclined tab is crossing with the central axis 101 of imput shaft, initiatively the central axis 15 of plain film is crossing with imput shaft central axis, and with the central axis of imput shaft central axis, initiatively inclined tab, two initiatively dial the axis of bolt in the same plane, namely in " active plane ".The central axis 15 of passive plain film is vertical with the central axis 1001 of driven axle and with the central axis 16 of the passive inclined tab be connected on driven axle, the central axis of driven axle, passive group of bolt in same plane, namely in " passive plane ".Active plane is also vertical with passive Plane intersects, and its intersection 17 is coaxial with the central axis of imput shaft and driven axle.
Imput shaft and the coaxial just theoretic saying of driven axle, be difficult to reach in actual manufacturing process, if both are rigidly connected, may produce statically indeterminate problem.But owing to having flexible connecting member between imput shaft and driven axle, therefore, even if there is the error manufacturing or install, make imput shaft and driven axle can not be coaxial, also can eliminate interference due to the existence of flexible connecting member, certainly, both coaxiality errors be the smaller the better.
Device described in the present embodiment is mainly used in the transmission between bearing circle and steering wheel, when also can be applied in the less moment of torsion of other transmissions.If be applied in the transmission between bearing circle and steering wheel, then described imput shaft is connected with bearing circle, and driven axle is then connected with steering wheel.
The core of the present embodiment is connecting strap imput shaft and driven axle being installed respectively similar " hook " shape.The one end of " hook " is fixed on imput shaft or driven axle, and fixing one end is called as " inclined tab ".And the part of " hook " of two " hooks " (being called " plain film ") is spatially parallel and form right-angled crossing spatially, arrange flexible connecting member between two " plain films ", moment of torsion is transmitted by flexible connecting member.Structurally, " inclined tab " and " plain film " is one, and can form with a block plate is bending or is formed by connecting with welding or bolt with several pieces, can there be one section of linkage section centre, forms complete " hook ".
Can be connected by the mode bonding with flexible connecting member between two plain films, but the bonding moment of torsion transmitted under normal circumstances is little, and also connects also lasting not.Another problem is the distortion often more difficult control due to flexible connecting member, therefore, simple use flexible connecting member and does not take the mode of any other transmitting torque, moment of torsion transmission just may be made to be obstructed, or damage flexible connecting member.
For solving the problem, the present embodiment takes the structure dialling bolt.Two plain films arrange a pair group of bolt respectively.Allowing and dial bolt through flexible connecting member, stirring flexible connecting member and transmitting torque by dialling bolt.Simultaneously shifting fork piece is set initiatively dialling the position that bolt stirs, limit initiatively dial bolt stir scope.The process of such actual transfer moment of torsion is: imput shaft-active inclined tab-active plain film-initiatively dial bolt-shifting fork piece-passive group bolt-passive plain film-passive inclined tab-driven axle.And flexible connecting member just plays the effect of reset, whole moment of torsion transmits reliably solid, can transmit larger moment of torsion.At this, shifting fork piece plays crucial effect in transmitting torque.In actual manufacturing process, shifting fork piece and passive plain film can be made of one.
Theoretically, on active plain film, also shifting fork piece can also be set, as long as the position of correct installation two shifting fork pieces, make two shifting fork pieces simultaneously stressed when transmitting torque, just can transmit larger moment of torsion.When there is shifting fork piece on both sides, just do not have the differentiation of imput shaft and driven axle, can choose at random any is imput shaft or driven axle.
Angle between the central axis of described " inclined tab " and the central axis of imput shaft or driven axle can change as required.
Described flexible connecting member can have certain elastomeric material formation with various, such as: the material such as rubber, plastic cement.Also the thrust baring with torsion spring can be used, but this rigid construction, benifit be there is no to damping vibrations, just off-axis and transferring power.
Embodiment two:
The present embodiment is the improvement of embodiment one, is the refinement of embodiment one about inclined tab.Active inclined tab described in the present embodiment, the central axis of passive inclined tab and the angle 40-90 degree between imput shaft and driven axle central axis.
Angle between active inclined tab described in the present embodiment or passive inclined tab and imput shaft or driven axle
α(shown in Fig. 2,3) can select at 40-90 degree.This angle can not be too little, if too little meeting makes the structure of whole off-axis long, is very disadvantageous to the mechanical equipment that this structural requirement of automobile is compact.
When
αwhen angle reaches 90 degree, whole " hook " becomes " door " font, transmitting torque that equally can be correct.Even working as
αwhen angle reaches more than 90 degree, only otherwise produce and interfere, transmitting torque can be realized equally.
Embodiment three:
The present embodiment is the improvement of above-described embodiment, is the refinement of above-described embodiment about flexible connecting member.The material of the flexible connecting member described in the present embodiment is the one in rubber or plastic cement.
Finally it should be noted that, below only in order to technical scheme of the present invention to be described and unrestricted, although with reference to preferred arrangement scheme to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention (shape of such as each key element, the connection mode of whole device, each annexation etc.) or equivalent replacement, and not depart from the spirit and scope of technical solution of the present invention.
