Specification

We claim:
1. An' linear closed loop actuator unit (200), said unit (200) comprising:
a top mount (208); a base mount (404) to mount said linear closed loop
actuator unit (200) on a vehicle (10);
5 a transmission unit (405), said transmission unit (405) securely disposed
inside a base system (401);
an electric machine (402), said electric machine (402) mechanically coupled
to said transmission unit (405);
a transmission box (403), said transmission box (403) comprising an electric
10 control unit (500) and
said electric control unit (500) electrically coupled to one or more sensors;
wherein
said electric control unit (500) electrically connected to said electric
machine (402) and
15 a rotatory motion of said electric machine (402) actuates said transmission
unit (405) in one or more direction of at least one side of said vehicle (10).
2. The linear closed loop actuator unit (200) as claimed in claim 1, wherein
said electric machine (402) actuates said transmission unit (405) in at least
one of an upward and downward direction.
20 3. The linear closed loop actuator unit (200) as claimed in claim 1, wherein
said electric machine (402) actuates said transmission unit (405) along an axis of said transmission unit (405).
4. The linear closed loop actuator unit (200) as claimed in claim 1, wherein
said transmission unit (405) converts a rotary motion of said electric
25 machine (402) into a linear motion in an at least one of an upward or
downward direction.

arm (204); said linear closed loop actuator unit (200) comprises a
transmission unit (405), said transmission unit (405) securely disposed
inside a base system (401);
an electric machine (402), said electric machine (402) mechanically coupled
to said transmission unit (405);
a transmission box (403), said transmission box (403) comprising an electric
control unit (500) and
said electric control unit (500) electrically coupled to one or more sensors;
ft.
wherein
a rotatory motion of said electric machine (402) actuates said transmission unit (405) dynamically in one or more linear direction of at least one side of said vehicle (10).
9. The vehicle (10) as claimed in claim 8, wherein said linear closed loop actuator unit (200) is removably attached to a rear arm (201) of said three-wheeled vehicle.

11. The vehicle (10) as claimed in claim 8, wherein said vehicle (10) is a three-wheeled vehicle or a four-wheeled vehicle.
12. A method for maintaining stability of a vehicle (10), said method comprising:
detecting a change of a contact angle of at least one wheel of a pair of
transversely adjacent wheels by at least a first sensing device;
detecting change of a position of said at least one wheel by at least a second
sensing device;
applying load to at least a first wheel of said pair of based at least on
detection of said change of contact angle by a microcontroller; and
reducing load of at least one wheel of said pair of transversely adjacent
wheels.
13. The method for maintaining stability of a vehicle (10) as claimed in claim 12, wherein said change of said contact angle during banked road condition.
14. The method for maintaining stability of a vehicle (10) as claimed in claim 12, wherein said change of a position is a difference between an actual position and reference position of said pair of transversely adjacent wheels.
