Volvo truck suspension parts – to give you a smoother ride
Suspension is a very important part of a truck. It is the chaining system between the sets, the shock absorber and the springs. This is the one that will absorb the vibration of the vehicle driving on the road and will absorb the shocks received when driving on uneven terrain. The suspension supports the braking system and allows it to react efficiently by braking instantly when necessary.
Good suspension parts are not only important for absorbing shocks while driving, but they are also important for preventing the truck’s occupants from feeling them. Volvo has been around for 80 years and in that time they have tried to perfect their suspension system and its parts.
Since the trucks have attached trailers behind them, they have front and rear suspensions. Volvo trucks have an air suspension system that not only stabilizes the ride, but also increases its comfort. In the rear cabin there are suspension air bags that are placed outside the frame of the rails. This gives the cabin greater stability when turning. There are side shock absorbers that minimize the roll of the cabin. Rubber shock absorbers that are hardened and used in the suspension system, which absorb strong shocks received in the cabin.
Then there’s the Volvo T-Ride suspension that has rubber towers and trunnion-mounted springs that give the truck an excellent ride even in the worst driving conditions. This plays an important role in off-road driving situations.
