Why hard axis, than the independent suspension of off-road vehicles off-road performance is better?
The so-called hard axis refers specifically to the rigid (front) bridge axle, also known as the overall bridge, the entire rear (front) bridge is a rigid overall, left and right roulette can only relative to the whole in the axle axis For the rotation movement, can not move around, equivalent to a wheel attached to the two wheels, so called "hard axis". Some people here to ask, is not what we said that the non-independent suspension? This year there are non-independent suspension of the car ah? Yes, hardcore suv is used in non-independent suspension. Because the cross-country, if the use of independent suspension, when the side of the wheel on the bomb will lead to the middle of the differential gap between the smaller, and the hard axis is not the concern. In addition, the suspension of the hard axis is generally longer than the independent suspension, when the side of the suspension is compressed, the other side of the suspension can be stretched as far as possible, which is very suitable for potholed road conditions.
Non-bearing body is the car has a rigid frame, also known as the chassis beam, the carriage carrying the entire body, the engine, suspension and body are installed in the frame. The biggest advantage of this structure is the high strength of the body, steel frame can provide a strong body rigidity, in the bad road, the vibration of the frame through the elastic components spread to the body, most of the vibration is weakened or eliminated, even if the four wheels by Force uneven, but also by the frame to bear, and will not be passed to the body, the body plays a protective role.
To off-road performance is good, then the comfort should be greatly reduced. Relatively hard suspension for running high speed, I think it should be more suitable for off-road truth
