1 noun. Explanation 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 is no relative movement such a suspension structure.
2. The basic structure of the whole 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 no 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.
integral structure type of axle shaft
from the axle shaft of the integral structure type, it can be divided into semi-floating and full-floating axle two kinds of Types of. 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 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.
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 the center of the wheel, the drive wheel axle via a gear train mounted on both ends of the axle, this axle construction is more complex, multi-emphasis for use under extreme off-road vehicle environment.
3. The overall advantages and disadvantages axle suspension
● strong bearing capacity
Since the load with a tube bridge portion or all of the vertical loads, so the overall bridge suspension of the carrying capacity of really outstanding, took consumers are 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 off-road use and harsh environment
Since the structure is relatively simple, it can withstand more torque, while using solid axle suspension coil spring suspension generally comprises greater than much travel in the rugged environment allows four 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, Toyota FJ cool Road Chak and other models are based on the overall suspension bridge typical.
● facilitate maintenance and modification
Also, since the structure is simple, and other parts of the axle bridge operating at a closed tube, so that the entire bridge structure and easy routine maintenance 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 modified off-road areas in terms of very high value, if the same number of teeth modified front and rear differentials, the differential can only be replaced without having to replace other components, but alsoSetting does not affect other parts of the suspension, compared to other types of multi-link suspension, the modified integral bridges is much easier.
● road performance in general
● comfort in general
but the overall axle suspension also has its own inherent shortcomings that It is at highway, bouncing sided wheels on the same axis will directly affect the other side 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 this suspension bridge type, in favor of tracking and comfort are better multi-link suspension, or other types.
