Trailer axle can be integrated, like a huge weight, both ends by suspension system to support the body, so integral axle of trailer usually cooperate with the independent suspension;
Trailer axle can also be broken open, like two umbrella in on both sides of the car body, and their respective through suspension system to support the body, so breaking axle of trailer and independent suspension.
To bridge structure is basically the same, is composed of two steering knuckle and a beam.
If the beam to the body, steering knuckle is the head, he swung his neck is that we often say that the king pin, wheel is installed on the steering knuckle, like the head with a straw hat.
However, when you drive, turn straw hat, head did not turn, middle separated with bearing, head just sway.
King pin is wheel rotation axis, the axis axis is not perpendicular to the ground, the wheels themselves are not vertical, there is a lesson in wheel alignment.
The difference between the steering drive axle and steering axle is everything is hollow, beam into a bridge shell, steering knuckle became a steering knuckle shell, because inside the root drive shaft.
Because of this drive axle is located in the middle of the bridge shell differential in two, and turned into two half shaft.
Two hat is not simply set on the head, with the inside of the two half shaft directly connected.
Half shaft in & quot;
Neck & quot;
The location of the - also have one more joints
Universal joint, so half shaft is turned into two parts, inside outside half shaft and half shaft.
