A leaf spring device includes a main leaf made of a steel plate including an elastic section configured to generate elastic force when bent; and an eye section formed in an end portion of the elastic section, the elastic section and the eye section being tempered. There is also provided a method for manufacturing the leaf spring device. The eye section is formed by rolling the end of the elastic section into a circular form. The eye section is tempered at a higher temperature than the elastic section.

A method for determining an axle load and a suspension system are configured for a vehicle having at least one leaf spring connected at its ends in spring holders of a vehicle body and connected in its central region to a chassis of the vehicle. The following steps are performed: measuring a measurement distance of the vehicle body relative to the chassis; determining whether there is currently a loading or unloading process of the vehicle, determining a relevant hysteresis curve of a pre-stored hysteresis field depending on the determination of a loading or unloading process, and determining a current axle load projection value from the measurement distance and the relevant hysteresis curve. A loading process criterion and an unloading process criterion may be considered. The determined axle load projection value thus serves as a projected or estimated axle load. Furthermore, the hysteresis field can be updated.

A safety strap apparatus for use with a vehicle's super single tire to protect a rim of the tire from damage during a tire blowout is provided. The super single tire and rim are coupled to an axle mechanically coupled to a frame of the vehicle by a shock absorber. The safety strap apparatus includes a strap assembly having a first elongated strap coupled to a second elongated strap, the strap assembly having a left end portion having an overlapped portion with end portions of the first and second elongated straps and a right end portion including another end portion of the first elongated strap, the left and right end portions being coupled together to create a loop. The loop is disposed around top and bottom portions of the shock absorber. Tension in the strap assembly supports the rim above the ground during the tire blowout.

An axle tie rod adapted to be secured to an axle tube of a utility vehicle includes a connecting element and at least one link element, wherein the connecting element has a first connecting section in which a welded connection with the link element can be produced, wherein the connecting element has a second connecting section in which a welded connection with an axle tube can be produced, and wherein the second connecting section is configured to engage around the axle tube.

An axle arrangement for a baler having a chassis includes a first axle having opposite ends and a pair of suspension cylinders, with each suspension cylinder positioned at a corresponding end of the first axle to accommodate generally vertical loads. The first axle is coupled with the chassis to accommodate generally horizontal loads. A second axle has opposite ends and a pair of suspension cylinders, with each suspension cylinder positioned at a corresponding end of the second axle to accommodate generally vertical loads. The second axle is coupled with the first axle to accommodate generally horizontal loads.

A vehicle rigid axle with an axle beam, at the ends of which axle journals or wheel carriers, are arranged, and trailing arms rigidly attached with a spring bracket for supporting an air-suspension bellow, and a method for manufacturing the vehicle rigid axle. An axle beam section extending between the trailing arms, a trailing arm adjoining the axle beam section and the spring bracket are formed by two shell elements connected to each other, which form a hollow body. In an embodiment, the spring bracket is formed by a lower shell element forming an axle beam section extending between the two trailing arms, and the spring bracket is arranged so that the air-suspension bellow mounted on the spring bracket is penetrated by the central longitudinal axis of the axle beam section. Two shell elements made of sheet metal are formed and joined together to form a hollow body.

An axle arrangement is provided having a wheel carrier with fastening arms. By placement of an assembly opening in the fastening arm in a motor vehicle transverse direction (Y), it is possible to fix the track width with the use of identical parts.

An axle suspension system and a method of manufacture. The axle suspension system may have an axle, an axle wrap, and a weld seam. The axle wrap may have first and second wrap portions that mechanically interlock with each other and that have overlapping ends that may receive a weld seam.

A vehicle including a frame; a motor; at least one ground engaging member; at least one suspension member pivotally connecting the ground engaging member to the frame; at least one double bonded bushing being disposed in an end portion of the at least one suspension member; at least one wear plate disposed between a first end of the at least one double bonded bushing and the frame, the at least one wear plate being rotationally fixed relative to the frame, the first end of the at least one double bonded bushing abutting the at least one wear plate, the at least one wear plate being selectively removable from the vehicle; and at least one shaft extending through a portion of the frame, the at least one double bonded bushing, and the at least one wear plate.

In a particular embodiment, a vehicle load measurement system is described that includes a chassis configured to support a body of the vehicle. In this embodiment, the vehicle load measurement system also includes a suspension system and a plurality of angle sensors attached to the suspension system. Each angle sensor is configured to measure an angle with respect to height. In this embodiment, the plurality of angle sensors include a first sensor attached to the first side of the suspension system configured to measure a first angle and a second sensor attached to the second side of the suspension system configured to measure a second angle. According to this embodiment, the first angle and the second angle are combined to obtain a combined value representative of axle load.
