What is the overall bridge?

1, the basic structure of integral bridges

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 without relative motion, such a suspension structure. Suspension bridge almost the whole of history associated with the birth of the car started, the development of today, 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 type structure, 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, only to climb Wrangler and other known models still in use. 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 spring, torsion spring or the like is more rare type elastic member. 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.
Further, the entire axle and axle suspension does not mean 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 wheel center, the 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.

2, the advantages of integral bridges

Strong

1. Bearing Capacity

Since a load bridge portion or all of the burden of the tube in the vertical direction, so the overall carrying capacity of the suspension bridge really outstanding, the consumer took more familiar with the Great Wall Hover, its quality has reached the maximum load 629 kg, 400 kg bearer quality far beyond the general car up and down. And they use a leaf spring suspension bridge pickup plus a whole load capability is even more alarming, in the domestic automotive products catalog has been designated to the ranks of light trucks. For harsh environments 2.

Since the structure is relatively simple, can withstand more torque, while using solid axle suspension includes a coil spring suspension generally much larger than the stroke in the rugged environment allows four wheel better get a grip, so that the continuation of the off-road race car most of the overall structure of the bridge or the bridge before and after the whole is still used, such as the Mercedes-Benz G-series, land Rover defender, Jeep Wrangler and Toyota FJ cool Road Chak and other models are based on typical overall suspension bridge. 3. To help maintain

Also, due to the simple structure, axle and other parts are running in a closed bridge tube, so the overall bridge structure easy daily maintenance and targeted modification, whether you are for everyday use or off-road enthusiasts, the whole bridge “operation” will be a lot simpler. For example, differential lock refit a very high value in terms of cross-country areas, front and rear differentials modified if the same number of teeth, only need to replace the differential can be, without having to replace other components, but it will not affect other parts of the suspension settings, compared to other types of multi-link suspension, the overall conversion bridge is much easier.

3, the overall bridge the shortcomings

1. road performance in general

but the overall axle suspension also has its own inherent shortcomings, that is in the highway, single side wheel bounce will directly affect the other side of the same axle of the wheel, which results in the overall speed axle suspension performance and comfort are more general. So now some of the original suspension bridge with the overall high-end SUV models have begun to gradually give up the whole bridgeThis type of suspension, and switch to the tracking and comfort are better multi-link suspension, or other types. 2. Using a small

for a compromise to comfort and road performance, and now with the overall suspension bridge models has been relatively small, but this does not deny its practicality and off-road enthusiasts status in mind, due to the overall suspension bridge structure is simple, easy maintenance and modification, and therefore carries that emphasize off-road models will continue to follow this suspension.
