A Brief History of the Steering Wheel & Power Steering Fresno CA

There are two types of conventional power steering systems. The first type uses a hydraulic cylinder attached to the drag link and the chassis.

A Brief History of the Steering Wheel & Power Steering

It's 1956 and the 20-inch-diameter steering wheel on a Chevrolet Bel Air or Ford Fairlane provided the leverage to steer the wheels. But, it was especially difficult to turn the steering wheel when the vehicle was stopped. Turning the wheel required a certain amount of upper body strength that was given by God to truck drivers of the day.

When the Saginaw recirculating ball steering gear was introduced on the 1940 Cadillac, it provided a little more mechanical advantage, but it was still hard to turn the wheel when the vehicle was stopped. If the car makers of the era were going to sell more vehicles, especially to the new suburbanite homemakers, they were going to have to be easier to steer and shift. The premium vehicles, Cadillac, Lincoln and Chrysler, were adding power steering to their optional and standard equipment lists, but they were still the most expensive cars in the dealers' showrooms.



By the start of the 1960s, power steering was an option or standard on all American-built vehicles. In the late 1960s and into the early 1970s, the big steering wheel still graced steering columns. The large diameter of the steering wheel made the power steering very sensitive to input at higher speeds. To reduce the input sensitivity, the diameter of the steering wheel was made smaller. Most vehicles today have a 14- or 15-inch steering wheel.
