Definitions
- ABSTRACT A window regulator for vehicles having a reversible motor provided with a sectional drive shaft, one section having a worm meshing with a worm gear which forms a part of a spring clutch.
- the clutch has a regulator pinion for connection to the usual gear sector of a window regulator.
- One section of the drive shaft is connected to the armature of the electric motor and the sections are connected by a torsion bar, rectangular in cross section and which extends freely through the shaft sections but extends into sockets at the outer ends of these sections, the sockets being rectangular in cross section.
- a reversible electric motor is connected to a window regulator through operative connections including a worm, and a worm gear which form part of a spring clutch device.
- a torsion bar affords the drive from the motor to the worm.
- An output pinion forms part of the spring clutch device and this meshes with the gear sector of the window regulator.
- FIG. 1 is an elevational view with parts broken away showing a vehicle window power regulator embodying a torsion bar drive and spring clutch or brake unit for retaining the vehicle window in its position of adjustment;
- FIG. 2 is a sectional view substantially on the line 2--2 of FIG. 1;
- FIG. 3 is an exploded view of the parts of the spring clutch assembly
- FIG. 4 is a fragmentary sectional view of the outer end portion of the armature shaft section.
- FIG. 5 is a transverse sectional view substantially on the line 55 of FIG. 4.
- the illustrated embodiment of the invention comprises a power operated vehicle window regulator mechanism having a gear sector with which is associated suitable lever and linkage for raising and lowering the window.
- Meshing with the gear sector 10 is a driving pinion 11 having an integral elongate hub ll2 from which extends an integral sleeve 13 in axial alignment with bores of the hub and pinion.
- the pinion 11, its hub 12, and sleeve 13 are rotatable about a bearing post 14 having a reduced axial extension 15 which is knurled and fits snugly into a hole in a cup-shaped housing part 16.
- the end of the extension 15 projects through the housing aperture and is upset or riveted over as indicated at 17.
- a reduced neck on the bearing post 1 1- receives and O-ring seal 18.
- the driven member 20 has a flat sheet metal ringlike body 21 which projects radially beyond the spacer ring 19 and has a pair of diametrically opposed arms 22, there being notches 220 formed in the body part 21 on each side of each of said arms.
- the arms 22 extend at approximately right angles to the body 21 and are arcuate in cross section.
- annular drive member 23 For actuating the driven member 20 and forming part of the spring clutch is an annular drive member 23 which may be of nylon or other suitable material, and, as shown in FIG. 3, is of annular form, a worm gear 2A being formed in the periphery thereof.
- the drive member 23 has a hub portion 25 which has an axial bore to fit the sleeve 13 and rotate thereon.
- Webs 26 connect the hub portion 25 with arcuate sectors 27 and encircling the sectors 27 is a helical wire spring 28 which has hooked or inturned ends 29 and 30 adapted to extend into the space between an arm 22 of the driven member and an edge of the sector 27 of the drive member.
- the lock spring 28 is housed within a cup 31 in which it can expand against for tight frictional engagement or contract to enable rotational movement.
- the housing cup 31 has a flange .32, and formed in the edge portion of the flange 32 are notches 33 into which extend ribs 34 on the housing part 16 for holding the cup against rotary movement relative to the associated parts.
- Closing the open end of the housing part 16 is a plate 35 of ring shape which is secured in place by screws 36 engaging lugs 16a projecting laterally from the housing part.
- an elastomeric sealing ring 37 is disposed principally on the inner side of the end plate 35, and is clamped into position between the plate 35 and the mouth of the housing part 16.
- the inside face of the end plate 35 has a stepped circular flange 33, which the rim portion of the gasket 37 is shaped to fit.
- the inner edge of the closure plate 35 is embraced by a gasket portion 39, and projecting from the outer side of the portion 39 is an annular blade which has wiping contact with the rotating spacer ring 119.
- a lower housing part 41 is integral with the housing part 16 and disposed therein is a hollow shaft section 412, on the outside of which is a worm meshing with the worm gear 24.
- the angularity of the teeth on the worm 42 is of the order of 9, or only slightly above the angle of friction.
- the outer end portion of the shaft section 42 is rotatable in an adjustable bearing plug 43 which has screw threaded engagement with the housing part 41.
- the bearing plug 43 has a socket 44 in the inner end in which the end portion of the shaft section 42 rotates.
- a thrust plate 45 against which bears a thrust ball bearing 46 which fits a cup-shaped cavity in the end portion of the shaft section.
- the opposite end of the shaft section 42' extends into a bearing sleeve 47 which also receives the adjacent end portion of a hollow shaft section d8 constituting the shaft of the armature for a reversible electric motor indicated at A9.
- the housing for the motor d9 has mounting posts 50 to enable the assembly to be suitably mounted in a vehicle door, for example.
- the opposite end portion of the shaft section 48 is mounted in a bearing 51 carried by a block 52 suitably secured to the motor housing.
- the block 52 is socketed to receive a thrust plate 53 against which a ball 54 bears, the latter being disposed in a cup-shaped cavity in the end of the shaft section 48.
- the drive from the shaft section 18 to the shaft 42' is through a torsion bar 55 which is square in cross section, and extends freely through hollow bores in the shaft sections.
- the shaft sections are cylindrical in cross section, except for the end portion 56 of the shaft section A2 which is square in cross section so as appropriately to fit the torsion bar.
- the opposite end of the torsion bar fits the end portion 57 of the shaft section d8, which is also square in cross section.
- the torsion bar is nonrotatable with respect to the shaft sections 42 and 48, but has limited axial movement.
- a vehicle window regulator comprising a rotary electric motor, output shaft from said motor, a worm on said shaft, thrust bearing for opposite ends of said shaft, adjustable means for effecting relative axial adjustment for said thrust bearings, a spring clutch having a driving member provided with a worm gear meshing with said worm, said spring clutch having a contractable and expansible coil spring, a driven member constituting part of the spring clutch, and a regulator pinion connected rigidly to said driven member.
- a vehicle window regulator as claimed in claim I characterized in that the angularity of the teeth of said worm is above the angle of friction.
- a vehicle window regulator as claimed in claim I characterized by means to cause the armature of said electric motor to act as a dynamic brake for resisting reverse movement of said shaft upon stopping of the regulator movement.
- a vehicle window regulator comprising a rotary electric motor, a pair of aligned independent hollow shaft sections one of which is connected to said motor, a torsion bar extending freely through said shaft sections and having its ends secured against rotation relative to the outer ends of said shaft sections, a worm on one shaft section, a spring clutch having a driving member provided with a worm gear meshing with said worm, said spring clutch having a contractable and expansible coil spring, a driven member constituting part of the spring clutch, and a regulator pinion connected rigidly to said driven member.
