We Claim:
1. A motion platform for a driving training simulator for the simulating different motion encountered by the vehicle cabin during the movement of the vehicle it comprise of:
The base frame (1, 2) connected to the top frame (8). The vehicle cabin is mounted on the top frame.
Pitch / Roll actuating unit (3) coupled to the base frame (1,2) with bottom coupling (9) and to the top frame (8) with top coupling (11). Surge / Sway actuating unit (5) coupled to the base frame (1,2) with bottom coupling (9) and to the vertical column unit (10) with top coupling (11). Yaw actuating unit (7) coupled to the top frame (8) with bottom coupling (9) and to the vertical column unit(10) with the top coupling (11).
2. The motion platform as claimed in claim 1 , the connection of top & bottom frame comprise of vertical column unit (10), that hold a coupling (9) on which the top frame (8) is coupled.
3. The motion platform as claimed in claim 1, wherein the base frame and top frame consist of welded cross members, made of steel channels and plates.
4. The motion platform as claimed in claim 1, wherein the actuator bottom coupling comprises rectangular plates, pins and locking clamps made of steel; the said bottom coupling having a freedom of rotation about the longitudinal and transverse axes. The actuator top coupling comprises steel rectangular blocks and pins and having a freedom of rotation about the longitudinal and transverse axes. Both the said vottom and top couplings being provided to facilitate pitch, roll, yaw, surge and sway motions.

5. The motion platform as claimed in claim 1, wherein each of the pitch actuating unit, roll actuating unit, yaw actuating unit, surge actuating unit and sway actuating unit comprise a screw and nut, said screw being driven by a belt powered by an electric motor and the said screw is provided to move up or down depending upon the direction of the motor rotation..
