Abstract
The present invention provides a power assist steering system for a vehicle having a wheel. The steering system includes a first reciprocating member coupled to the wheel such that reciprocating movement of the first reciprocating member provides turning movement of the wheel, a steering input engaged with the first reciprocating member such that rotation of the steering input provides reciprocating movement of the first reciprocating member, and a steering assist assembly including a second reciprocating member engaged with the steering input such that reciprocating movement of the second reciprocating member provides an assist force to the steering input. Preferably, the first and second reciprocating members engage the steering input at locations opposed to each other and also move along paths that are substantially parallel to each other.
