1. The entire suspension bridge
that is integral with an integral bridge structure connecting two wheels of the axle, the axle can not be disconnected, two wheels on the same axle is no relative movement. Overall suspension bridge has a long history, developed to its structure has not changed much. For the drive axle, the mainly by the differential housing, axle tubes, axle, bearings and other parts, and for the whole non-bridge drive axle, its structure is more simple, and now more for freight cars.
from the axle shaft of the integral structure type, can be divided into semi-floating and full-floating axle two types. Semi-floating axle is directly connected to the hub, in addition to receiving a driving force outside the longitudinal axle torque receiving end further from the hub, which load is limited, but the simple structure, light weight, and thus used for early cars and light trucks, now rare. Full floating axle and by a flange, connected to the hub bearing, axle only the driving force is transmitted without receiving torque from the bridge to withstand a longitudinal axle torque, a wider range of applications, now employed most integral bridges suspension of passenger cars use full floating axle structure.
In addition to the difference in the opening axle, axle suspension integral main difference is also reflected in the suspension with the elastic elements described above, there is more common leaf spring, a coil spring of two types, in addition to the air springs, torsion bars the resilient member relatively rare type of spring or the like. Strong bearing capacity steel springs, simple structure, it is also very easy to maintain, the disadvantage is the limited tire trajectory, road performance and comfort in general. And a coil spring to provide greater freedom of travel of the tire, and the need for a plurality of auxiliary connecting rod, a complicated structure, in addition to repair a number of relatively complicated.
[greater stroke of the coil spring, off-road situation conducive to the limit, but requires a plurality of link connecting axle and the vehicle body]
Furthermore, axle suspension does not mean that the whole axle and directly connected to the wheel center, because, for the purpose of lifting the vehicle ground clearance, a lot of off-road vehicles using a configuration of the portal axle, axle shaft will be higher than the wheel center,Driving axle via a gear train wheel mounted on both ends of the axle, this axle construction is more complex, multi-emphasis for use under extreme off-road vehicle environment.
the overall advantages and disadvantages of suspension bridge
Advantages:
1, strong carrying capacity;
2, off-road and for use in harsh environments; [123 ]
3, conducive to the maintenance and modification;
disadvantages:
1, road performance in general
for a compromise to comfort and road performance, the overall now suspension bridge models has been relatively small, but this does not deny its usefulness and status in the eyes of off-road enthusiasts, due to the overall suspension bridge structure is simple, easy maintenance and modification, and therefore those that emphasize off-road models will carry continue to follow this suspension.
