2. TIPE COLLAPSIBLE
Tipe collapsible is divided into 3 types , namely

B. Ball type
C. Solid silicon rubber type
A. MESH TYPE
Column structured mesh and divided into two main shafts, top and bottom which are connected with plastic pins, the column bracket mounted capsule. In the event of a collision, the steering gear box under pressure, then the main shaft of his column willcollapse, so the driver avoid a collision when the steering wheel and driver's body hit the steering wheel column, the cap-sule bracket will be released and the main shaftand its column pressed down.

Column was composed of two parts, top and bottom which are connected with the mediation of ball bearings.
Main shaft consists of thetopand bottom which areconnected with plastic pins.
When the vehicle got a loud crash and the steering gearbox under pressure, then the column and its main shaft will shrink and manpower-gapress willbe absorbed bythe ball bearings in pairs between the lower tube and uppertube, so the driver avoid a hazard .
