In the embodiment of the present application, as it is shown in figure 1, the center by yoke 2 is defined as inward-outward direction to peripheral direction.
As shown in Figure 1 to Figure 3, the present invention provides a kind of double; two roller three pin-type to move universal joint, including there is the bearing pin 1 of spindle nose 11 and being set in the yoke 2 outside bearing pin 1, yoke 2 inwall is provided with yoke alley 21, being arranged with internal trolley 12 on spindle nose 11 and be arranged with outer roller 13 in internal trolley 12 lateral wall, the lateral wall of outer roller 13 and yoke alley 21 sidewall lean; Internal trolley 12 can roll relative to spindle nose 11, and outer roller 13 can roll relative to internal trolley 12 and yoke alley 21. The present invention by being arranged with internal trolley 12 and being arranged with outer roller 13 in internal trolley 12 lateral wall on spindle nose 11, the lateral wall of outer roller 13 and yoke alley 21 sidewall lean, thus the swing degree of freedom added between internal trolley 12, outer roller 13 and yoke alley 21, and decrease the frictional force between internal trolley 12, outer roller 13 and yoke alley 21; And then ensure that the present invention operationally produced noise is relatively low. Meanwhile, overall structure of the present invention is relatively simple, be easy to processing and manufacturing, production cost is relatively low.
In the application, bearing pin 1 is three bearing pins, and namely on this bearing pin 1, spindle nose 11 quantity is 3 and 3 spindle noses 11 center circumferentially array distribution along bearing pin 1, and each spindle nose 11 is in the cylindrical-shaped structure extended along inward-outward direction. Meanwhile, above-mentioned yoke alley 21 also has 3. And between outer end and the yoke alley 21 of above-mentioned spindle nose 11, there is gap 3, to avoid spindle nose 11 directly to contact with yoke alley 21 and to produce frictional force when spindle nose 11 moves relative to yoke alley 21 between the two.
As it is shown in figure 1, be provided with needle roller 14 between the medial wall of the lateral wall of spindle nose 11 and internal trolley 12, needle roller 14 can roll relative to spindle nose 11 and internal trolley 12; Thus also ensureing that internal trolley 12 can freely roll relative to spindle nose 11 and reduce frictional force between the two.
As it is shown in figure 1, the lateral wall of spindle nose 11 is provided with lock ring 15 at the outer end place corresponding to internal trolley 12, lock ring 15 is used for limiting internal trolley 12 and slides in and out along spindle nose 11. Meanwhile, as it is shown in figure 1, lock ring 15 includes the lock ring 151 being set on spindle nose 11, the outer rim place of lock ring 151 is provided with outer defining flange 152. Outer defining flange 152 is for leaning with the outer end of internal trolley 12 and the medial wall of internal trolley 12, to prevent the center of internal trolley 12 from skew occurring, internal trolley 12 is made to be respectively provided with good matching relationship with needle roller 14 and outer roller 13, thus ensureing that internal trolley 12 can roll freely.
It addition, as it is shown in figure 1, lock ring 15 also includes the bail wire 153 being set on spindle nose 11 and being positioned at lock ring 151 with the outside of spindle nose 11 junction. This bail wire 153 can effectively limit above-mentioned lock ring 151 and be displaced outwardly along spindle nose 11. Meanwhile, as depicted in figs. 1 and 2, spindle nose 11 is provided with detent 111, and bail wire 153 is embedded in detent 111. In the present embodiment, the cross section of bail wire 153 is rounded.
As shown in figures 1 and 3, yoke alley 21 sidewall is provided with alignment concavity 211 at the lateral wall place of leaning with outer roller 13, and outer roller 13 is contacted by least two anchor point 213 with alignment concavity 211. The application China and foreign countries roller 13 is contacted by least two anchor point 213 with alignment concavity 211, this kind of contact form namely ensure the external roller 13 of alignment concavity 211 there is positioning function, the rotating direction that makes outer roller 13 parallel with yoke alley 21 all the time, meanwhile, between outer roller 13 and alignment concavity 211, the form efficiency of point cantact reduces frictional force between the two.It addition, as shown in figures 1 and 3, in the present embodiment, the cross section of alignment concavity 211 is curved, and the cross section of this alignment concavity 211 may be used without the versions such as triangle in other embodiments, outer roller 13 is same with the cross section of the side that alignment concavity 211 leans curved. as shown in Figure 1, outer roller 13 is contacted by two anchor points 213 with alignment concavity 211 in the present embodiment, and two anchor points 213 are symmetrically dispersed in the alignment concavity 211 of arc, when roller 13 rolls relative to alignment concavity 211 so outside, external roller 13 is applied two along alignment concavity 211 center position by two anchor points 213, and symmetrical active force, the two active force acts on outer roller 13, external roller 13 plays effective positioning action, ensure that the center of outer roller 13 is corresponding with the center of alignment concavity 211, and then ensure that the rotating direction of outer roller 13 is parallel with yoke alley 21 all the time.
As shown in figures 1 and 3, yoke alley 21 sidewall is provided with auxiliary positioning face 212 at the outer end place corresponding to outer roller 13, and auxiliary positioning face 212 leans for the outer end with outer roller 13. When roller 13 rolls relative to yoke alley 21 outside, outer roller 13 can be subject to outside relative force; Now, the outer end of auxiliary positioning face 212 and outer roller 13 leans, this auxiliary positioning face 212 can apply the active force with above-mentioned thrust reversing to outer roller 13, effectively prevent outer roller 13 from offseting relative to yoke alley 21, thus ensureing that outer roller 13 has good matching relationship with yoke alley 21. It addition, as it is shown in figure 1, outer roller 13 and auxiliary positioning face 212 place of leaning are positioned at root 131 place of outer roller 13 outer end, to ensure that outer roller 13 can freely roll.
It addition, as depicted in figs. 1 and 2, the sidewall that above-mentioned bearing pin 1 center is provided with through hole 16 and through hole 16 is provided with the sawtooth 161 connecting shape. The cross section that the outer surface of yoke 2 is provided with 3 outer grooves 22 and outer groove 22 is curved. It addition, the center of above-mentioned spindle nose 11 is provided with elastic breach 112, and this elasticity breach 112 cross section is horn-like in what expand from inside to outside; Above-mentioned elastic breach 112 makes spindle nose 11 have certain deformability, in order to install above-mentioned lock ring 15, internal trolley 12 and outer roller 13 etc. on spindle nose 11.
In sum, the present invention effectively overcomes various shortcoming of the prior art and has high industrial utilization.
Above-described embodiment is illustrative principles of the invention and effect thereof only, not for the restriction present invention. Above-described embodiment all under the spirit and category of the present invention, can be modified or change by any those skilled in the art. Therefore, art has usually intellectual such as modifying without departing from all equivalences completed under disclosed spirit and technological thought or change, must be contained by the claim of the present invention.
