Abstract
The invention discloses a kind of novel torsion bar shaft of locking locking gear, including torsion bar shaft and anti-loosening locking block, torsion bar shaft one end evolution slot, along one lateral circular hole of diameter of axle direction processing and parallel with square groove in the middle part of slot；End face processes a pilot hole, aperture is wide slightly larger than square groove, latch segment is mounted in torsion bar shaft square groove, by locking blind rivet, stop nut, antifriction ring is assembled into, locking blind rivet one end is machined with spherical expansion cap, when locking torsion bar shaft, locking blind rivet screws out outward along torsion bar shaft pilot hole, change torsion bar shaft outside diameter by expansion cap, fasten torsion bar shaft and worm gear shaft, stop nut opens an annular groove by plain nut and injection molding nylon material forms in annular groove, after locking blind rivet fastening, play good anti-loosing effect, antifriction ring can prevent torsion bar shaft not to be rotated in locking, keep torsion sensor assembly symmetry constant.After sensor unit centering, torsion bar shaft end latch segment, Shaft alignment state that is easy to operate and not changing sensor unit only need to be screwed with spanner.
Description
Technical field
The present invention relates to a kind of torsion bar shafts for electric powered steering transmission device locking locking gear.
Background technology
Currently, the torsion sensor assembly of electric powered steering transmission device after in, between torsion bar shaft and worm gear shaft or passes
The two is tightened together by the way of draw-bore, pressure straight pin between moving axis.
Pressing straight pin fastening, there are many disadvantages.For example, since pin hole is that radially, pressing-in force when being pressed into straight pin makes torsion
Bar axis is amesiality, reduces the symmetry of electric powered steering transmission device, influences steering behaviour.
The further drawback of said mechanism is that craftsmanship is poor, and cylinder pin hole easily bores partially, and the precision in hole is not easy to ensure, and is difficult
Detection, torsion bar shaft hardness is high, drill bit easy fracture, and inefficiency.
More also the disadvantage is that, once by straight pin be pressed into pin hole in, when detect product it is unqualified when, can only subscription rate, nothing
Method is reprocessed.
Invention content
The present invention is to provide a kind of novel torsion bar shaft of locking locking gear, including torsion bar shaft and anti-loosening locking block, turns round
Bar axis one end evolution slot processes a lateral circular hole at the middle part of slot along diameter of axle direction, and parallel with square groove, and torsion bar axial end separately adds
One pilot hole of work, aperture slightly larger than square groove it is wide, anti-loosening locking is packaged in the square groove of torsion bar shaft, by locking blind rivet, stop nut,
Antifriction ring is assembled into, wherein locking blind rivet one end is machined with spherical expansion cap, when locking torsion bar shaft, locking blind rivet is along torsion bar
The pilot hole of axis screws out outward, changes torsion bar shaft outside diameter by expansion cap, to which torsion bar shaft and worm gear shaft to be fastened on
Together, stop nut is by opening an annular groove in plain nut, and injection molding nylon material forms in annular groove, when locking blind rivet fastening
Afterwards, good anti-loosing effect can be played, antifriction ring can prevent torsion bar shaft not to be rotated in locking, to ensure that torsion senses
The symmetry of device assembly is not changed.After torsion sensor assembly centering, the locking of torsion bar shaft end only need to be screwed with spanner
Latch segment, it is easy to operate, and do not change the Shaft alignment state of torsion sensor assembly.
The advantages of patent of the present invention：
The present invention is to provide a kind of novel torsion bar shaft for electric powered steering transmission device locking locking gear, to eliminate
The defect of current used technology no longer needs to draw-bore after this novel torsion bar shaft assignment, and hole of extending sales, hinge pin hole is finally pressed again
The complicated procedures such as straight pin ensure that the symmetry of torsion sensor assembly is unaffected, and due to easy to operate, be greatly improved
Working efficiency.
The present invention is also reworkable, and reprocesses operation very simple, avoids wasting, cost-effective.
The other advantage of the present invention is, since fenestra is not just outside not pin hole processing, with the joining worm gear shaft of torsion bar shaft
The axis shelves for reserving pin hole processing again, simplify design of part.

Specific implementation mode
【Embodiment】
After the torsion sensing receiver assembly of electric powered steering transmission device is completed on alignment test platform in, special spanner is used
Fixed stop nut 3, while rotation lock strains at nail 4 outward, and torsion bar shaft 6 is made to be fastened with worm gear shaft 1, and stop nut 3 is to lock
Strain at nail 4 and can play it is good locking and it is locking, when rotation lock strain at nail 4 when, antifriction ring 2 prevent torsion bar shaft 6 rotate, from
And it ensure that the Shaft alignment state of torsion sensor assembly and do not change.
Claims (1)
