Description
It is that U.S.'s non-provisional application of 0715-0171.01 is a preceence that the application requires U.S. Provisional Application 60/662,233 that proposed on March 16th, 2005 and the name that proposed on March 15th, 2006 to be called " axle tower " file number.
Background of invention
The present invention relates to components of suspension systems, for example axle location and/or load counteraction mechanism are connected to device on the axle shell.Particularly, the present invention relates to multifunctional axle location and/or load reaction device, for example torque box are connected to the axle tower (Axle Tower) on the axle shell.
Vehicle suspension system provides the comfortable vehicle borne goods transient vibration of taking and prevent for Vehicular occupant.Equally, also very important, suspension system also provides vehicle stability by controlling the various power that are applied on the vehicle bridge, otherwise this power can make vehicle bridge with respect to vehicle frame undesirable position change take place.Especially, this power changes vertical, the horizontal and/or lengthwise position of vehicle bridge with respect to vehicle frame, also can make vehicle bridge move for example inclination, skew and angular oscillation.Each parts of suspension system are reacted and are controlled one or more power.For complexity and the weight that reduces suspension system, the parts of suspension system are related to a plurality of power of control.
The torque box assembly is one of them such multipurpose multifunctional operating system.It is reacted to the vertical air spring load, and opposing braking/accelerating weight has center inclination resistant property, and opposing revolution or lateral load also keeps the position of vehicle bridge with respect to chassis side rail, also helps to prevent unsuitable skew and vehicle bridge angular oscillation.
Usually, the torque box assembly typically comprises the steel rectangular box structure of welding.The front and back end is welded on the round steel pipe.During assembling, continuous rubber bush inserts in these pipes, and the circular metal bar is arranged in axle bush.At an end of torque box, bar with link to each other across the crossbeam between the chassis side rail of vehicle frame.At the other end of torque box, each end of interior circular metal bar is connected on the axle tower successively, and wherein axle tower is connected to torque box on the vehicle bridge by axle shell.The torque box assembly is described in detail in U.S. Pat 6,527, discloses in 286.U.S. Pat 6,527, disclosed content here as a reference in 286.
Clearly, the load paths between axle shell and the torque box is very important.Here said connecting device or axle tower are with the device of these load transfer to the axle shell.These axle towers transfer are vertical, inclination is imported, horizontal and radial weight.Preferably, axle tower can axle shell do not transship and/or the situation of breaking under transmit load.
Asymmetric vehicle bridge is a standard in the North America.Asymmetric finger differential gear box skew axle center line.Asymmetric vehicle bridge is to being a challenge with axle location and/or the design that for example is connected to the connecting device of axle shell for the load reaction device of torque box.Torque box or other devices are usually located at the center between the chassis side rail of vehicle, thereby at the center of the opposite end of vehicle bridge.In order to make torque box or other device to the heart, the connecting device of axle tower and axle center line interval equidistance for example.Therefore, because differential gear box is in axle center, so axle tower is installed on the differential gear box and different distance place at interval, differential gear box line of centers both sides usually.In other words, axle tower is installed in about on the asymmetric point of the line of centers of differential gear box, and the line that connects this point of connection like this is out-of-level.
Like this, axle tower is usually designed to and differs from one another, to adapt to its asymmetric position about differential gear box.Because the installation site of adaptation on differential gear box has different basal body structures, axle tower also has differing heights and is parallel to all the other vehicle bridge with the transverse width that keeps torque box in addition.In other words, because comparable other axle tower of axle tower are positioned at the more high position on the differential gear box, so the axle tower that improves can be shorter than another axle tower, otherwise torque box can be with respect to all the other vehicle bridge deflections.
Axle tower must be able to be kept out the stress that torque box or other allied equipments apply, and this axle tower must absorb and/or disperse the power along axle shell, with the fault that prevents that vehicle bridge and/or differential gear box are possible.
Another connecting device known in the art is the vertical and horizontal torsion bar pylon that often runs on the highway suspension or connection " vee rod " pylon to the axle shell top.Yet it is multi-functional that these device propers do not have axle tower of the present invention and had.The unique distinction of axle tower of the present invention is that it is multi-dimensional, multi-functional structure member, i.e. the structure that the load that acts on many vehicle bridge is reacted, the function singleness of existing apparatus, the i.e. structure that load on the single vehicle bridge is reacted.For above-mentioned functions is provided, the various features that existing structure is improved are included in the axle tower of the present invention.
Will describe in detail as following, when radial weight was applied on the air bellow, torque box was in extended state and reacts by promoting axle tower.Because this cantilevered load in the axle tower, on axle tower, have compressed side (near torque box) and tensile side (with torque box apart from farthest).Therefore these both sides of axle tower can be designed to difference, so that effective design of bearing load to be provided.
In an embodiment of axle tower of the present invention, axle tower can comprise various features.These features will describe in detail below, be summarized as follows.The compressed side that a feature that can comprise is an axle tower is different with the tensile side shape of axle tower.Difformity influences the rigidity of pylon both sides, and improves distribution of pressure and reduce pressure load on the axle shell.Pylon both sides shape difference is that a side of bearing elevated pressures of axle tower has than axle tower opposite side or bigger knuckle-tooth or the profile of tensile side.
Another feature that can comprise is that the groove of interior connecting panel is asymmetric shape.Asymmetric concentrating by material makes stress concentration in groove one side, to be offset this higher stress value.In other words, bear elevated pressures a side have a more material.
Another feature that can comprise is that axle tower is connected to asymmetric impression on the axle shell.The compressed side of axle tower or the side with higher shear degree or sinuousness have at least one radius or round angle.The circle of axle tower compressed side or radius impression weaken axle shell by the dispersive stress load and have the effect of wedge angle.In addition, this impression has sizable width along axle shell.This helps the large tracts of land dispersive stress along vehicle bridge and differential gear box.
It is crooked and be obedient to that to be axle tower allow when vehicle bridge be out of shape under the load effect at the knuckle-tooth of compressed side or profile another feature that can comprise, do not have in the commissure simultaneously to transship.Do not have the structure of knuckle-tooth or profile can be harder, and can not be out of shape when vehicle bridge is out of shape, this can make the weld seam overload.
Another feature is the weldment of axle tower.Weldment is lighter, and cost is lower, and preferably integral body is the ordinary steel foundry goods.In addition, weldment does not need the required following process of foundry goods.Yet, axle tower is made rather than said method does not exceed scope of the present invention yet here by casting.Axle tower of the present invention also can serve as the torsion bar attaching parts.
