Actuator assembly

An improved actuator assembly comprising;

• a rack, a pinion engaging said rack, a rack and pinion housing surrounding said rack and pinion, and biasing means reacting between said housing and said rack for urging said rack into engagement with said pinion, said biasing means comprising an elongated metal spring member disposed in parallel relationship to said rack and crowned between the ends thereof.

An improved actuator assembly comprising;

• a rack, a pinion engaging said rack, a housing surrounding said rack and pinion, and cushioning means at each end of said housing for engaging said rack only at the extremes of rack travel.

An improved actuator assembly comprising;

• a rack, a pinion engaging said rack, a housing surrounding said rack and pinion, said rack having a bore extending therethrough, a guide tube secured to a first end of said housing and extending into said bore in said rack at all positions of travel of said rack.

An improved actuator assembly comprising;

• actuator means including a rack and pinion for converting rotary motion to rectilinear motion, a separate coupler for transmitting rotary motion to said pinion, a wheel bushing for receiving a steering wheel, said bushing being nonrotatably keyed to said coupler and removable from said keyed relationship with said coupler to be rotated relative to said coupler any one of various angular amounts and replaced in said keyed relationship with said coupler in any one of various angular positions relative to said coupler.
