Abstract
Abstract A rack and pinion steering gear assembly having a biasing yoke member positioned on the opposite side of the rack from the pinion, the yoke member being spring-urged against the rack to maintain the teeth thereof in contact with the teeth of the pinion, the rack having a curved surface contacted by the yoke, and the yoke being split to assure contact between the sides of the yoke and the sides of the housing opening receiving the yoke while maintaining contact with the rack.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
78 words
In a rack and pinion steering gear assembly having a rack bar received longitudinally of a housing and a pinion received transversely thereof with a yoke received in a recess of the housing opposite the pinion on the other side of the rack and effective to urge the rack into engagement with the pinion, the improvement of the yoke being split into two parts, the split lying in a plane normal to the axial plane of the rack.
Claim 2
Dependent Claim
78 words
In a rack and pinion steering gear assembly having a rack bar received longitudinally of a housing and a pinion received transversely thereof with a yoke received in a recess of the housing opposite the pinion on the other side of the rack and effective to urge the rack into engagement with the pinion, the improvement of the yoke being split into two parts, the split lying in a plane normal to the axial plane of the rack.
Claim 3
Dependent Claim
46 words
A yoke for use in rack and pinion steering gear assemblies comprising a cylindrical member having axial ends, one of said axial ends having a part cylindrical recess formed therein transverse of the yoke axis, the said yoke being split along its axis into two parts.
Claim 4
Dependent Claim
46 words
A yoke for use in rack and pinion steering gear assemblies comprising a cylindrical member having axial ends, one of said axial ends having a part cylindrical recess formed therein transverse of the yoke axis, the said yoke being split along its axis into two parts.
Claim 5
Dependent Claim
44 words
The yoke of claim 2 wherein the end opposite the end having the part cylindrical recess has a recess extending axially thereinto and terminating blind within the yoke, a portion of the axially extending recess being formed in each half of the split yoke.
Claim 6
Dependent Claim
192 words
A rack and pinion steering gear assembly comprising a housing, said housing having a longitudinal dimension, an opening extending longitudinally through said housing, a rack bar positioned in said opening, a pinion projecting into said housing transversely of said housing, said pinion having circumferentially spaced teeth therearound, said rack bar having teeth extending thereinto from the surface thereof, said rack teeth intermeshable with the pinion teeth, said rack bar having a surface opposite the said teetH, said housing having a recess thereinto communicating with the opening, said recess positioned opposite the pinion, said recess having a wall surface lying in a plane normal to the plane of the axis of the rack, a yoke received in said recess, said yoke comprising two mirror image parts each of which has an outer surface dimensioned to mate with the wall surface of the recess and a surface opposed to a surface of the other portion, each of said portions having an end surface configured to mate with the surface of the rack bar and means urging the said portions against the said surface of the rack bar and against the wall of the recess.
Claim 7
Dependent Claim
192 words
A rack and pinion steering gear assembly comprising a housing, said housing having a longitudinal dimension, an opening extending longitudinally through said housing, a rack bar positioned in said opening, a pinion projecting into said housing transversely of said housing, said pinion having circumferentially spaced teeth therearound, said rack bar having teeth extending thereinto from the surface thereof, said rack teeth intermeshable with the pinion teeth, said rack bar having a surface opposite the said teetH, said housing having a recess thereinto communicating with the opening, said recess positioned opposite the pinion, said recess having a wall surface lying in a plane normal to the plane of the axis of the rack, a yoke received in said recess, said yoke comprising two mirror image parts each of which has an outer surface dimensioned to mate with the wall surface of the recess and a surface opposed to a surface of the other portion, each of said portions having an end surface configured to mate with the surface of the rack bar and means urging the said portions against the said surface of the rack bar and against the wall of the recess.
