BASICS OF ATV SUSPENSION DESIGNING

                              BASICS OF ATV SUSPENSION DESIGNING

OBJECTIVE -

1. Designing a suspension which will influence significantly on comfort, safety and maneuverability.
2.Contributing to vehicles road holding/handling and braking for good active safety and driving pleasure.
3. Protect the vehicle from damage and wear from force of impact with obstacles (including landing after jumping)
4. Maintaining correct wheel alignment.

DESIGN METHODOLOGY -

The overall purpose of a suspension system is to absorb impacts from coarse irregularities such as bumps and distribute that force with least amount of discomfort to the driver. We completed this objective by doing extensive research on the front and rear suspension arm’s geometry to help reduce as much body roll as possible. Proper camber and caster angles were provided to the front wheels. The shocks will be set to provide the proper dampening and spring coefficients to provide a smooth and well performing ride.

FRONT SUSPENSION :

1. For our front suspension we chose one with a Double arm wishbone type suspension. It provided specious mounting position, load bearing capacity besides better camber recovery.

2. Front Unequal Non Parallel double wishbone suspension .

3. The tire need to gain negative camber in a rolling situation, keeping the tire flat on the ground .

                                             





REAR SUSPENSION                                                                       MONOSHOCK MOUNTING ON SWING ARM
For our Rear suspension we chose Swinging Arm with Monoshock type suspension. Using monoshock over dual shocks is advantageous due to ease of adjustment as there is only single damping unit and smaller unsprung mass.
