Information - Steering Gear

The given device is intended for transformation of the steering wheel rotation to the forward moving of the drive rods that causes turn of the directive wheels. Certainly, the effort passed by the driver from the steering wheel to the turned wheels increases many times. Together with the steering actuator, steering mechanism transmits the force from the driver to the wheels that provides a specified angle wheel turn. Moreover, the turn without sideslip is impossible without the wheels to slide on arches of different length. In their turn, front wheels turn on different angles. All this is fulfilled due to the connection of drafts and levers of a steering drive in the form of a trapeze.

Depending on the steering gear there are several types of steering mechanisms: worm gear, screw gear and toothed wheel gear. In the first gear type there is a worm that acts as a leading member. It is attached to the steering wheel shaft. Thus the roller is fastened on one shaft together with the pitman arm on the roller bearing. In the second (screw) type of the steering mechanism rotation of the screw, which is connected with the steering shaft, is passed to a nut. In toothed steering mechanisms cylindrical or conic toothed wheels form a steering gear. They also include the gear-rack transmission type, in which the cylindrical gear is directly connected to the steering shaft and the rack is mounted with the gear teeth. It acts as a lateral thrust.

The difference between all the steering mechanisms is not only in their structure, but also in the field of use. Thus, in the trucks steering gears like worm-sector and the screw-nut-sector are used, which are equipped with a built-in amplifiers or amplifiers that are in the steering. As for the cars, they use rack and worm-and-roller transmissions. Malfunction of the steering gear can cause serious problems. Therefore, if you need a new spare part or brake shoes, oil filter and radiator, it is much cheaper to buy them in our online store.

What is necessary to know about steering rack replacement: lifetime limits, common defects and their signs, tips and recommendations

Useful lifetime of the steering rack is about 150 000 - 200 000 operational kilometers.

Lifetime limit of the part largely depends on road surface quality, on which the car is exploited, and on the vehicle model.

Defects, which mostly lead to replacement of the component are wear of the rod, guiding sleeve and seals. Moreover, a new part is installed if deformation affected the housing, gears or toothed mechanism of the hydraulic steering rack.

Defective condition of the steering rack can be noticed by, first of all, knocking and screeching at maneuvers, free movement of the steering wheel at turning, troubled rotation of the steering wheel. Apart from these, defect may be indicated by traces of oil under the front part of the car and vibration of the steering wheel during straightforward movement on a rough road.

In order to check condition of the steering rack, in most cases, it is necessary to dismount and disassemble it. During this you need to set a car onto a servicing pit or lift, disconnect the steering rods and tie rod ends from the part, unscrew fastening of the steering rack and other elements of the steering control. The steering rack can be dismounted after that. Sometimes, demounting of the front wheels is necessary for it. These are laborious procedures, which are better to entrust to car service station specialists.

It is also advisable to perform replacement of the component at a service station. A new part will be installed after demounting of the old one: the left steering rack - for left-hand drive cars and the right one - for right-hand drive cars. It is necessary to replace the sleeve, seals, bearings (and the tie rods and tie ends in most cases) together with this part. Bleeding of the hydraulic system is performed after finishing of steering rack installation.
