Please consult Fig. 3, described the second link 32 comprises a body 34, reaches a plurality of driving arms 36 that radially extend from the body 34 axial the other ends from the connecting part 35 that body 34 axial ends extend vertically again.Described body 34 roughly is cylindric.The pilot hole 24 of the shape and size of described connecting part 35 and described output shaft 20 is complementary.In the present embodiment, the cross section of described connecting part 35 roughly becomes regular hexagon, is appreciated that ground, and described connecting part 35 cross sections also can be quadrilateral, pentagon etc., and other are non-circular.Described driving arm 36 is from the periphery of body 34 extending radially outwardly along body 34.Described driving arm 36 is circumferentially evenly arranged along body 34, is appreciated that ground, and what this place referred to radially is not radially strict.Preferably, described the second link 32 is made by metallic material.Preferably, described the second link 32 is by the mode moulding of metallic material by casting.
The connecting part 35 of described the second link 32 is contained in the pilot hole 24 of described output shaft 20, thereby so that the moment of torsion of the second link 32 can be passed to output shaft 20.In addition, the part body 34 adjacent with connecting part 35 is contained in the accepting hole 23 of output shaft 20.The purpose that accepting hole 23 is set in the present embodiment is in order to guarantee better the coaxality between the second link 32 and the output shaft 20.Be appreciated that ground, output shaft 20 also can only arrange pilot hole 24 and not establish accepting hole 23, and so, the connecting part 35 of the second link 32 is incorporated into that the pilot hole 24 of output shaft 20 is interior equally also can be passed to the moment of torsion of the second link 32 output shaft 20.At that rate, the thickness on the axial length of described body 32 is preferably axial along body 32 with driving arm 36 about equally, with the axial length of further optimization coupling 30.
Alternatively, described live axle 20 also can be connected by the attachment hole that flat position is set and be complementary with it with described the second link 32, as at the driving the tip of the axis flat position being set, correspondingly the connecting part of the second link is removed, change into the attachment hole that is complementary with described flat position is set in the body, thereby make live axle and the second link realize being connected.
The driving arm 36 of described the second link 32 is contained in respectively in the accepting groove 44 of described the first link 31, and each driving arm 36 is folded between the two adjacent bumps 43 of the first link 31, so that the first link 31 can drive 32 rotations of the second link when rotating, thereby driver output axle 20 rotations.Because certain buffer function plays to pedestal 40 in the wall section 63 of shock absorber 60 when transmission between the body 34 of the bump 43 of pedestal 40 and the second link 32, thereby reduction noise.
Described axial driving component 33 is spherical, and it mostly is steel ball.Described axial driving component 33 is contained in the receiving hole 42a of the first link 31, after 100 assemblings of torque drive composite set are finished, described axial driving component 31 is resisted against between live axle 10 ends and the second link 32, so that live axle 10 and the second link 32 also are mutually to transmit axial pressure between live axle 10 and the output shaft 20.Yet understandable, in the situation that live axle 10 directly contacts with output shaft 20, also can mutually transmit axial pressure, this moment, driving component 33 and corresponding receiving hole 42a all can arrange.
Preferably, described the second link 32 forms a containing groove 37 in the central authorities of an end at driving arm 36 places.Described containing groove 37 is blind hole.One column separator 38 is contained in the described containing groove 37 and is used for contacting with described axial driving component 33, thereby the axial pressure that axial driving component 33 is transmitted is passed to the second link 32, and then is passed to output shaft 20.Preferably, described separator 38 is formed through quenching by tool steel, and it has higher hardness, so can avoid when the second link 32 is made by the lower material of hardness, and axially driving component 33 is directly supported the second link 32 and caused 32 distortion of the second link.
Because the setting of shock absorber 60 is in order to cushion the impact force between the first link 31 and the second link 32, therefore, to be appreciated that ground, in the situation that shock absorber 60 is not set, coupling still can be realized the function of transmitting torque.In addition, live axle 10 is with the annexation of output shaft 20 and coupling 30 also exchangeable, and namely live axle 10 is connected to the second link 32, and output shaft 20 is connected to the first link 31.The above only is better embodiment of the present utility model, and not in order to limiting the utility model, all appropriate changes of doing within spirit of the present utility model and principle and be equal to replacement all should be included within the protection domain of the present utility model.
