Steering System То guide the car, it is necessary to have some means of turning the front wheels so that the car can be pointed in the direction the driver wants to go. The steering wheel in front of the driver is linked by gears and levers to the front wheels for this purpose. The front wheels are on pivots so they can be swung to the left or right. They are attached by steering knuckle arms to the rods. The tie-rods are, in turn, attached to the pitman arm. When the steering wheel is turned, gearing in the steering gear as- sembly causes the pitman arm to turn to the left or right. This move¬ment is carried by the tie-rods to the steering knucle arms, and wheels, musing them to turn to the left or right.The steering system incorporates: the steering wheel and column, steering gear, pitman arm, steering knuckle arm, front axle, steering knuckle pivot, tie-rods. There are several different manual steering gears in current use, such as the rack and pinion type and the recirculating ball type. The rack and pinion steering gear is widely used. Another manual steering gear which is popular in imported cars is the worm and sector type. The steering wheel and column are the source of injury to the driver, air bags and other devices being developed now to safe the life of a driver. Energy-absorbing columns must stop the steering wheel and col-umn from being pushed to the rear as the front of the car is crushed in an impact. Energy-absorbing columns must also provide the driver with a tolerable impact as he moves forward and strikes the wheel with his chest. Перевод текста
