    [1] The present invention relates to wheeled vehicles, such as trucks, and more particularly to a suspension system for such a vehicle.
    [2] A chassis of a truck typically includes a suspension system that includes suspension of a axle, such as a rear axle, from a chassis component, such as a chassis frame. The traction system absorbs road-induced forces as the vehicle is fed on the road, which contributes to the quality of the vehicle's road and driving characteristics.
    [3] One type of suspension system is a steel spring suspension system. Such a system typically includes a multi-leaf spring on the right side of the vehicle and a multi-leaf spring on the left side of the vehicle. The front and rear ends of the longest blade in each spring are mounted on the respective chassis component, such as the side rail on the chassis frame, via the respective front and rear leaf springs which are the first to the respective chassis component. It is possible that a jumper is arranged between one spirit of the longest blade and the corresponding first. A shaft is fixed to the suspension system by halfway between the front and rear fasteners, respectively, fastening a housing of the shaft to each multi-leaf spring.
    [4] When the vehicle is driven, vertical forces are transmitted to the shaft from irregularities in the underlying road surface. While these forces are partially mitigated by the suspension system, the forces are transmitted to the chassis via the leaf spring fasteners.
    [5] The use of a steel suspension suspension system on a chassis has the effect that it can maintain a correct position of the axle relative to the chassis and relative to other wheels than those on the axle. Proper placement of a drive shaft relative to the chassis provides a straight line feed which avoids creating a non-zero, or off-center, traction angle which creates a condition sometimes referred to as "dog tracking", which 1 contributes to an incorrect steering wheel adjustment because the driver must over- or understeer to correct for this. "Dog tracking" can lead to acute tire wear.
    [6] Another type of suspension system is an air suspension suspension system. Instead of steel spring blades, an air suspension suspension system has air springs on the hooks and the left side of the shaft allows it to absorb the vertical wall forces transmitted to the shaft. An air spring typically has a single attachment point to a chassis, unlike the mounting of a spring leaf on the front and rear leaf spring feedstocks. Proper alignment of the shaft with the chassis is provided by other parts of the suspension system than the air springs as the air springs cannot do this on their own.
    [7] A factory for the manufacture of vehicles can build some vehicles which have suspension springs and other vehicles which have air suspension systems. The difference in construction between these two suspension systems does not contribute to the possibility of using common parts in the systems.
    [8] This description refers to an air suspension suspension system that can use certain parts that are identical to or similar to those used in a steel spring suspension system. Consequently, the manufacturing cost can be kept down because a manufacturing plant can store fewer unique parts, these parts can be manufactured in larger volumes, and certain assembly steps may be common for the assembly of both types of suspension systems for a chassis.
    [9] The dangerous embodiment of the air spring suspension system comprises a shaft suspended from a chassis on a right and a left long arm. Each lung arm has a proximal end and a distal end. Correct positioning of the axle relative to the chassis of the support hall by a resiliently flexible right-hand locating belt and a resiliently flexible left-hand locating belt. Each locating band has a front end, a rear end, and a center portion between the front end and the rear end. 2
    [10] A right-hand attachment device secures the center of the right-hand locating band, a sheath of the shoulder, and the right-hand support arm halfway between its proximal end and its distal end. The proximal end of the right armrest is suspended on the chassis in a manner that allows the right armrest to pivot about a horizontal axis perpendicular to the direction of travel of the vehicle while the vehicle is steered in a straight line while an upward movement of the shaft acts on the right armrest. A higher air spring is disposed between the chassis and the distal end of the right lead arm beyond the shaft relative to the proximal end of the right lead arm.
    [11] A left-hand fixture encloses the center of the left locator band, a sheath of the shaft, and the left armrest halfway between its proximal end and its distal end. The proximal end of the left armrest is suspended from the chassis in a manner that allows the left armrest to pivot about a horizontal axis perpendicular to the direction of travel of the vehicle while the vehicle is steered in a straight line while an upward movement of the shaft acts on the left armrest. A left air spring Or is disposed between the chassis and the distal end of the left armrest beyond the shaft relative to the proximal end of the left armrest.
    [12] Each locating band maintains the horizontal axis about which the proximal end of each armrest can pivot perpendicular to the direction of travel of the vehicle while the vehicle is steered in a straight line, but without flakes significantly attenuating wall-induced force on the chassis which a steel spring suspension would support. This orientation of the pivot axis is achieved by relating the front end and the rear end of each locating band to a respective front and rear locating head on a particular seat and using the respective air springs to dampen substantially all of the wall-induced force.
    [13] Each front locating floor comprises side walls which define a neck which is the app in a downward direction and in a direction towards the rear locating floor. Each rear locating floor includes side walls which define a neck which is open in a downward direction and in a direction towards the front locating floor. The side walls have each front locating first limiting the front end of the respective locating band towards a substantial direction in a horizontal direction parallel to the axis about which the proximal end of the respective support arm pivots. The side walls 3 of each rear locating base define the rear end of the respective locating band against a substantial movement in a horizontal direction parallel to the axis about which the proximal end of the respective armrest pivots.
    [14] The present description relates to a vehicle comprising a chassis, a shaft with a housing, and a suspension system in which the axle is suspended from the chassis. The suspension system includes a support arm that carries a proximal spirit, a distal spirit, and a center portion between the proximal spirit and the distal spirit, a suspension that hangs the lead arm on the chassis for a pivotal movement about a horizontal axis passing through the proximal end of the lead arm and is perpendicular to the direction of travel of the vehicle while the vehicle is steered in a straight line, an air spring disposed between the chassis and the distal end of the lane arm, a resiliently flexible locating band having a front end, a rear end, and a center portion between the front end and rear end, a fastening device which holds the center of the resilient flexible locating band, the center of the lanyard arm and the shaft, a front locating first fixed to the chassis, a rear locating first fist at the base behind the front locating fixture, the front locating fixture comprising the side walls the locating band horizontally in a direction parallel to the horizontal axis about which the lead arm pivots, and the rear locating bracket includes side walls which locate the rear end of the resilient flexible locating band horizontally in a direction parallel to the horizontal axis about which the longitudinal arm pivots.

The fasteners 28, 30, 32 and a fastener for shock absorbers 34 are arranged against an outer vertical surface of the left side rail 12 and fixed to this side rail.
    [21] The left arm arm 22 includes a proximal spirit 56, a distal spirit 58, and a central portion that is between the proximal spirit 56 and the distal spirit 58. The proximal spirit 56 includes a strut 60 having a central portion enclosed by a bushing which is arranged in one eye of the lintel arm 22. The inner and outer spirits of the strut 60 project the Iran bushing and contain hall 62 which allows the strut 60 to be fastened with fasteners 52 to the left front locating strap bracket 28.
    [22] From the proximal spirit 56, the left long arm 22 is initially straight and extends toward the rear of the chassis 10 more horizontally than vertically to a location beyond the rear axle 20 where it extends vertically downward to a length where it extends further backwards. to the distal spirit 58 where the arm prepares food.
    [23] The left locating band 26 includes a front end 64, a rear end 66 and a center portion 68.
