Renault Duster cars are equipped with steering with a gear-rack type steering mechanism and a hydraulic booster

The steering gear consists of two steering rods connected by ball joints to the steering knuckle arms of the front suspension

Особенности рулевого управления Renault Duster

The steering gear is mounted on the front suspension subframe and is secured to it with two bolts.

In the steering gear housing, the rack is pressed against the pinion shaft by a spring through a stop.

The adjustment of the lateral clearance between the gear and the rack is performed by rotating the adjusting plug, which presses the spring.

The adjustment is made when the steering gear is assembled at the factory.

The steering gear consists of two steering rods connected to the steering rack and steering knuckle arms.

Each rod is attached with its inner end to the steering rack through a non-separable ball joint - the threaded end of the joint is screwed into the hole in the rack.

In the middle part of the steering rod there is a hexagon wrench "for 13", and at the outer end there is a thread on which the rod end is screwed.

The tie rod end has a non-separable ball joint that does not require replenishment of the lubricant stored inside it for the entire service life.

The right and left tie rods are the same, but the tips are different.

The connection between the steering rack and the ball joint of the steering rod is protected from dirt and moisture by a corrugated rubber boot.

The cover is fixed with a steel disposable clamp on the steering gear housing, and the cover is held on the steering rod by a spring clamp - while the narrow belt of the cover must coincide with the groove made on the steering rod.

The steering column shaft is attached to the steering gear shaft through an intermediate shaft with two cardan joints.

On the splines in the upper part of the steering column shaft there is a steering wheel secured with a screw.

The steering column is attached to a cross-member bracket located under the dashboard.

The power steering system includes: a steering gear, a pump, a radiator for cooling the working fluid, a reservoir for the working fluid and connecting pipes of the lines.

Особенности рулевого управления Renault Duster

The pump is driven by a belt from the accessory drive pulley.

The hydraulic fluid from the reservoir enters the pump, and from it is supplied under high pressure to a distributor located in the steering housing and mechanically connected to the steering column shaft.

The hydraulic cylinder piston is fixed on the toothed rack of the steering mechanism.

When the steering wheel is turned, the distributor connects one of the chambers of the hydraulic cylinder to the pump discharge line, and the other chamber to the drain.

In this case, the piston of the hydraulic cylinder, due to the pressure difference of the working fluid, moves the rack to the left or right and through the steering rods, and the levers of the fists turns the steered wheels of the car.

A radiator for cooling the working fluid is built into the drain line of the power steering.

The radiator is located behind the front bumper - mounted on the front suspension subframe in front of the air conditioning condenser and the cooling system radiator.

If the hydraulic booster fails, the ability to control the vehicle is retained, but the effort on the steering wheel increases.

The power steering reservoir is installed in the engine compartment - secured with a clamp on the radiator fan shroud.

To control the liquid level, the semitransparent body of the tank is marked with MIN and MAX marks.
