A beam axle, solid axle or rigid axle could be a dependent suspension style, within which a collection of wheels is connected by one beam or shaft.
Beam axles were once ordinarily used at the rear wheels of a vehicle. However, traditionally they need additionally been used as front axles in rear-wheel-drive vehicles. In most vehicles, beam axles are replaced eventually by front and rear freelance suspensions.

The Twist-beam rear suspension could be a similar suspension style. However, its beam axle is in a position to twist thereby functioning as AN anti-roll bar to manage the roll motion of the body and is taken into account to be a semi-independent suspension style.
Front Axle Beam
The drawbacks square measure that it doesn’t permit every wheel to maneuver. Severally in response to bumps, and also the mass of the beam is an element of the unsprung weight of the vehicle. Which might additionally scale back ride quality. Also, the cornering ability is often worse than alternative suspension styles as a result of the wheels have zero camber angle gain throughout body roll.
Front beam-axle suspension is additionally unco sensitive to any lack of disk shape within the hub and wheel assembly which might cause an area oscillation (“shimmy”) of the steering at bound speeds (typically 40-50 mph). This is addressed on some vehicles with steering dampers though removal and careful refitting of the front wheels often cures the matter.
