رک و پین کن steering uses a gear-established to convert the circular motion of the steering wheel into the linear motion required to turn the tires. It also offers a gear reduction, so turning the tires is easier.
It functions by enclosing the rack and pinion gear-set in a steel tube, with each end of the rack sticking out from the tube and linked to an axial rod. The pinion gear is attached to the steering shaft so that when the steering wheel is turned, the apparatus spins, moving the rack. The axial rod at each end of the rack connects to the tie rod end, which is mounted on the spindle.
Most cars need three to four complete turns of the tyre to move from lock to lock (from far to far still left). The steering ratio shows you how far to turn the tyre for the tires to carefully turn a certain amount. An increased ratio means you have to turn the tyre more to turn the wheels a particular quantity and lower ratios give the steering a quicker response.
Some cars use adjustable ratio steering. This rack and pinion steering system uses a different number of tooth per cm (tooth pitch) in the centre than at the ends. The result is the steering is more sensitive when it’s turned towards lock than when it’s close to its central placement, making the car more maneuverable.
دو نوع سیستم فرمان رک و پینیون وجود دارد:
End take off – the tie rods are attached to the end of the steering rack via the inner axial rods.
Centre remove – bolts attach the tie rods to the centre of the steering rack.
As steering is vital for controlling your vehicle, it’s important to diagnose and repair any steering problems as quickly as possible.
این احتمال وجود دارد که ماشین شما دارای فرمان دندانه دار و دندانه دار باشد.
Thankfully, the fundamentals aren’t hard to understand at all: it’s all about turning rotational motion into linear. When you change the steering wheel, this turns a steering column, which rotates the attached steering shaft and a worm equipment known as the pinion. This equipment sits on the ‘rack’, a length of metal with a series of teeth cut into it. So as the pinion rotates, the rack moves either left or right, based on your steering input.
Power steering adds a device to one side of the rack with a hydraulically actuated piston inside. A rotary valve directs hydraulic liquid to either the proper or left aspect of the piston – depending on the steering path – which applies strain on the piston and reducing your time and effort needed to move the rack.
چرخ دنده رک و پینیون دو کار انجام می دهد:

It converts the rotational movement of the tyre into the linear motion needed to turn the wheels.
کاهش دنده را ارائه می دهد ، که چرخاندن چرخ ها را آسان تر می کند.
On the majority of cars, it takes 3 to 4 complete revolutions of the tyre to help make the wheels turn from lock to lock (from far left to far right).
