How does collapsible steering column work?
In simple terms, the column is comprised of an inner and outer sleeve with a number of bearings contained between each sleeve. On impact, the sleeves will compress much like a telescope. This means that on any frontal collision, the steering column will absorb the energy produced during impact by collapsing.
What do you mean by collapsible steering column?
The collapsible steering column is a type of advanced steering column. It is a part of the passive safety system in cars. It is also known as ‘Energy absorbing steering column’. Engineers invented it to reduce the risk of injuries occurring to the driver in case of frontal impacts.
Why does a collapsible steering column collapse?
A common device to enhance car safety is the collapsible steering column. This is designed to collapse in the event of a collision to protect the driver from harm. The column can collapse after impact with a tolerance ring inserted between the inner shaft of the steering column and the external housing.
When was collapsible steering column invented?
Steering Column: Though the collapsible steering column was invented in the 1930s, GM didn’t begin installing them until 1967.
What is steering column lock?
Electronic Steering Column Lock is a theft deterrent feature that locks the steering column while the vehicle is off and the driver’s side door is opened. The column remains locked until the vehicle is turned on with the key fob present.
Which is connected to the steering column?
The steering column of a vehicle is the rod to which the steering wheel is attached. The steering wheel is mounted on a shaft inside the steering column. The steering column carries the steering inputs to the steering rack or box. The steering wheel is connected to a shaft that runs through the steering column.
What is energy absorbing steering column?
In automobile: Safety systems. Interior-impact energy-absorbing devices augment restraint systems by absorbing energy from the occupant while minimizing injuries. The energy-absorbing steering column, introduced in 1967, is a good example of such a device.
What is the cause of noise in steering?
When the power steering rack is worn out, it starts making noise while turning. This whining sound is most recognizable while driving at a slower pace. Sometimes a bad belt or vane pump can also cause this problem. Tie rods enable the wheels to move in response when you turn a steering wheel.
How do you know if your steering column has collapsed?
Here are a few signs to watch for that could mean your steering column is failing:
- Steering tilt function does not lock.
- Clicking or grinding sounds while turning the steering wheel.
- Steering wheel operating roughly.
- Steering wheel doesn’t return to middle.
Why are collapsible steering columns used in cars?
Collapsible steering columns were introduced to reduce the number of serious injuries caused by the impact of the steering column and wheel on the driver’s body in the case of a frontal impact collision whilst driving.
How does a tilt steering column work on a car?
The arch stays connected to the ignition switch pushrod as the sector rotates about the tilt pivot pin when the column is tilted, without moving the pushrod. The pushrod pulls up as the key is turned toward the START position, and pushes down as the key is turned to the OFF position.
Which is a type of energy absorbing steering column?
EASC (Energy Absorbing Steering Column) is a kind of Steering Column which minimizes the injury of the driver during a car accident by collapse or breaking particular part of system. In this paper, a case study is performed on an existing steering column of Maruti-800 passenger car.
What’s the difference between automatic and manual steering columns?
The column shown is for a manual transmission equipped Fiero as indicated by the key release lever. Automatic columns use a different ignition switch that has a provision for an interlock cable that runs to the shifter mechanism. I will detail the internal differences between the two types of columns during the build.
