3 Chassis
Steering is composed of steering wheel, steering shaft, steering gear type "rack and pinion" and steering gear. The steering wheel with an integrated driver's front airbag is mounted on a shaft that transmits control movements to the steering mechanism. The steering column switch assembly is installed behind the steering wheel. To keep the airbag in contact with the SRS control unit when the steering wheel is turned, there is a coil spring that can twist and unwind. The coil spring consists of a tape with internal conductive tracks. The steering column can be adjusted for both reach and tilt.
To facilitate driving, a 3rd generation electromechanical power steering with two drive gears is installed as standard. A separate gear is added to the simple steering mechanism, acting on the steering rack and driven by an e / motor. The torque sensor on the steering shaft acting on the steering wheel with the steering angle sensor is located in the steering gearbox. Communication takes place via the CAN data bus. The advantages of such a design include:
- low power consumption (the booster uses power only when it is actually working, when the steering wheel is turned);
- missing hydraulic components (pump, lines and power steering reservoir);
- minimum transmission of shocks to the steering wheel (e.g. when driving on a rough road);
- low noise transmission to the vehicle;
- function "active return" promotes the return of the wheels to a straight position.
Loosening problems often occur when repairing or servicing suspension and steering components "stuck" bolts and nuts. Fasteners located under the bottom of the car are constantly exposed to external influences and eventually corrode and partially collapse. The use of brute force in releasing such "stuck" fasteners are at risk of damage. To start, dampen the anti-twist element with a small amount of special penetrating fluid (e.g. WD-40), allowing it to soak the rust layer well. Use a wire brush to remove external deposits from the accessible areas of the threaded surfaces. Sometimes a sharp blow with a hammer on the nut through the drift helps to destroy the rust that fills the gaps between the turns of the threaded joint - try not to damage the threads as a result of the drift slipping off. Use when giving away "stuck" fasteners of a long crank allows you to significantly increase the applied torque, however, it should be remembered that the use of extension cords complete with ratchet-type drives is associated with the risk of failure of the return mechanism, as well as the possibility of injury. Self-locking nuts and fasteners damaged by corrosion or when removed during repair must be replaced without fail. Welding and straightening are not allowed on power-bearing bearings and suspension components that guide the wheel.
Since most of the procedures described in this chapter are performed on a car raised above the ground, you should take care of the options for its reliable fixation in a raised position in advance - prepare strong props. To jack up the car, use hydraulic rolling jacks - remember that the onboard jack included in the standard package is intended only for temporary jacking up the car when replacing a failed wheel. The hydraulic jack can also be used to hang some suspension components when performing a particular procedure. Before carrying out work, secure the car on the paws of the lift using safety belts.
Attention: It is not allowed to carry out work under the car, which is held in a raised position only by means of jacks!
