This document discusses different mechanisms for electric motor assisted tilting in vehicles. It addresses the working principles, requirements, constraints, and designs of tilting mechanisms using electric motors, hydraulic pistons with spring-dampers arranged inline or in parallel, and hydraulic piston cylinder assemblies. Calculations are presented for pressures, forces, and tilting based on these various assisted tilting mechanisms.

2. Electric Motor Assisted Tilting Mechanism

3. Working Principle

4. Causes Of Failure
Stresses Induced In Mount

5. Motor Requirement
The motor installed has to tilt the whole chassis and
transfer the weight on either side
Such a high torque motor requires more power from
the source
Thus it is necessary to install high capacity battery.
Which adds to cost and space of the car. The cost of
motor is also to be considered.

6. Motion Of Linkages

7. Space Constraints
The over assembly consist of a motor, a chassis
mount and a horizontal linkage attached to the motor
in addition to the normal car without tilting
mechanism.
Overall system becomes bulky.
