    2) In the leaf spring design, the spring assemblies maintain fore-and-aft positioning ofthe wheels and transfer braking torque.

 

    3) On some vehicles the steering gear converts the turning of the steering wheel tofore-and-aft movement of the pitman arm，which is then converted to side-to-side linkagemovement by a specially shaped steering arm.

 

    4) Power steering provides most of the force needed for steering. The remainingsteering effort provides needed driver "feel" for good steering control.
