Replacing clunking steering shaft in Chevy Silverado
Power dissipation management in a frontal collision.
Provide mounting for the multi-function switch, the locking of the column, the wiring of the column, the column shroud s, selector transmission speeds, gauges or other instruments, as well as the hydraulic motor or electro and reducers present in the power steering.
Height and provides or adjusting the length according to the preferences of the driver seat position.
The steering column consists of a collapsible housing containing a rotating shaft foldable For safety reasons, the steering column is designed to collapse in the event of an end before collision If a steering column is collapsed, it must be replaced the steering shaft is a two or more workpiece components located inside the steering column is supported at the top and bottom of the column direction by bearings the steering column housing may also contain shift components in normal road cars, the steering column is used to mount various accessories the turn signal switch, head lamp dimmer, wiper switch, and the ignition switch can be located on or inside the steering column steering column service usually requires the removal of these components care must be taken when the steering column for repair column must not be abandoned, pressed, or subjected to blows to each end of the internal components of the column can shear, which causes the partially c ollapse column.
For a racing sport where hundredths of a second can make the difference between pole position or grid midfield slot, the ability to manage a car is paramount The steering system allows the driver to his first indication how the car handles the steering column is an essential link in the chain of events that sees a torsion of the steering wheel turning the wheels of the car the column is connected to the steering wheel at one end and the rack and the sprocket to another This means that the steering column extends from the edge of the passenger compartment down to the partition of the survival cell before.
Rack and pinion steering column components in road cars.
Simply, if the driver turns the steering wheel, the column rotates the pinion and the rack moves laterally the tie rods are actuated, moving the wheels The tie rods are used to connect the steering box to the direction the knuckle pulling ends are a ball and socket design that allows the coupling rod to flex up and down with the movement of the suspension rods before tie should be inspected for excessive movement, sealing tears grease or visible wear You should not be able to cut the ball and socket assembly of the coupling bar trying to squeeze the hand all inward movement of the ball must be considered excessive wear .
Tie rod ends are of spherical design which allows the connecting rod to flex up and down with the movement of the front suspension.
Many modern cars use mechanisms steering rack and pinion, where the steering wheel turns the pinion; the pinion moves the rack, which is a linear gear which meshes with the pinion, converting a circular motion into a linear motion along the transverse axis of the car side lateral movement This movement applies a torque direction on the kingpin of the steered wheels via the connecting rod and a short lever arm called steering arm.
The design of the rack and the pinion has the advantages of a high degree of feedback and direct steering feel; it normally does not also have a reaction or SLACK why this system is the first choice designer Race One drawback is that it is not adjustable, so that when it carries and develop lash, the only remedy is the replacement .
High performance steering column is constructed primarily from carbon fibers or high-quality steel, titanium and aluminum, and consists of two tubes and are connected together by a constant velocity joint, this which ensures that both parties are moving at the same speed it also provides high stiffness and low friction if there is too much friction or stiffness not enough, then it will have an adverse impact on the way the driver can manage the car.
In formula 1 and some other classes, the column has an electrical plug that connects the electronic steering wheel to the electronic control unit via a wiring harness This end of the column also has disconnection fast, which means that the driver can remove the steering wheel in a hurry There is a rule that FIA F1 driver must be able to exit the car in five seconds, the quick disconnect is very important .
At the end of the steering rack of the column, a spline joint is used to bond the two together, it then connects to the valve power steering and then to the pinion, the power steering pump supplies the hydraulic pressure used for 'steering assist power steering pump is driven by a gear fixed on the crankshaft pinion of the power steering pump rotates a vane assembly within a pump ring located inside the pressure of the pump is created by the compression of the fluid between the blades and the surface of the ring of the pump of the pump output pressure is maintained by a flow control valve comprising an internal pressure relief valve there two types of power steering pumps used immersed and not immersed both are similar in operation, with the only difference being the fluid reservoir type used a type of submersible pump contains the pump and fluid reservoir in a unit has not immersed uses a fluid reservoir at a distance from the pump.
Without the power steering, which in a racing environment uses high pressure hydraulic power, the driver should work with management twice harder Some modern road cars use instead of the power steering, electric motor to help driver electric power steering is designed to use an electric motor to reduce stress by providing help to the driver most EPS assistance systems have variable, which allows greater speed assistance to a decrease of the vehicle and less aid system at high speed situations EPS is more efficient than hydraulic power steering, since the electric power steering motor only needs to provide assistance when the steering wheel is turned while the hydraulic pump must run continuously EPS level Assistance is easily tunable to the vehicle type, road speed, and even the driver's preference An additional advantage is the elimination of environmental hazard caused by leaks and the removal of hydraulic fluid from steering.
Another of the conditions for Formula 1 designer steering column component is fixed by the FIA This is aluminum crush tube They must perform a crush test in which they fall on a weight to the end of the column direction and measuring the deceleration the peak deceleration must be less than 80 g in an accident.
For security reasons all modern cars feature a collapsible column energy absorbing steering steering column will collapse if heavy frontal impact to avoid excessive injuries to non-collapsible steering column conductors impale very often the drivers in a frontal collision Audi has a retractable wheel system called Procon Procon-ten-ten is a safety restraint system owner used by the German automaker, from 1986 until mid 1990 Audi was the one of the last German manufacturers to employ airbags in their cars, primarily because of the high reliability and cost effectiveness of the technology they called Procon-ten brand collapsible steering columns were invented by Bela Barenyi.
Formula 1 steering column takes about ten hours to make, and the team takes three or four spares along each race they are inspected after completing 1,500kms and maintained after 3,000kms A typical serving would involve a complete dismantling, followed by a crack monitors critical safety parts could then reassembled - with new parts if necessary - and finally tested on the test bench before being signed-off for use on the circuit.
Arriving in a design that is both lightweight and rigid yet reliable, the steering column do not regularly change, however, frequent design reviews are conducted and a new design will be implemented if the changes enough monohull.
Technical specification for Formula 1 steering column length 950 mm diameter 35 mm Material carbon fiber, titanium, steel, aluminum.
