Technical field
The present invention relates to automotive transmission, and in particular to a kind of automotive transmission sprag clutch.
Background technology
The work of sprag clutch depends on the collective friction element for being known as sway brace, it is by sway brace in inner and outer rings
Between wedging act on and transmit moment of torsion.Basic sprag clutch is mainly by outer shroud, inner ring, groups of sway brace, interior holding
Frame, outer retainer and spring etc. form.For sway brace to transmit the load bearing element of moment of torsion, inside and outside retainer passes through its ring flange point
The radial positioning mode of certain interval is kept with inner and outer rings to realize guiding role, keeps sway brace phase one in carrying
Cause, so that carrying is uniform.The main function of spring is to make sway brace and inner and outer ring moment keep contacting, ensure clutch with
When from status transition is surmounted to wedging state.
Sprag clutch involved by patent document CN201010599537.6, referring to Fig. 1, its outer shroud and inner ring all use
Split structure.Outer shroud is divided into the first outer ring body 14 and the second outer ring body 15, the first outer ring body 14 and the second outer ring body 15
By being interference fitted and welding together, without annular left groove on its outer shroud；Inner ring is divided into the first inner ring body 20 and
Two inner ring bodies 21, the first inner ring body 20 and the second inner ring body 21 are by together with spline fitted；The ring flange 40 of interior retainer 4 compares
It is shorter, therefore 4 heat treatment hardness of interior retainer cannot be too high, hardness is too high to cause heat treatment deformation big.The method of interior retainer 4
Blue disk 40 is directly radially positioned on the second inner ring body 21.Its 40 and second inner ring body 21 of ring flange is passed through using interior retainer 4
Following problem can be brought by keeping the radial positioning mode of certain interval.Due to interior retainer and inner ring phase under surmounting state in the limit
13000rpm can be up to rotating speed, so the radial positioning mode easily causes 40 and second inner ring of ring flange of interior retainer 4
