A system for dynamically managing individual suspension settings for a vehicle based on a determined suspension mode is provided. Based on the user input and obtained sensor input, the system can then determine a suspension mode for a plurality of individually controllable components by specifying values or commands for each controllable component. A first mode may correspond to a lowering of the plurality of controllable. A second mode may correspond to lowering two controllable components corresponding to the rear wheels of the vehicle and raising two controllable components corresponding to front wheels of the vehicle. A third mode may correspond to a lowering of the plurality of controllable components to effectively drop the height of the vehicle to a threshold point. The system may further implement various validation processes that can validate the determined suspension mode and make further adjustment to individual controllable portions based on load or ground measurements.

A height-adjusting axle assembly separate from and connectable to a trailer frame. A first pair of wheels is connected to a first cross-beam by a first pair of torsion axles such that rotation of the first cross-beam causes rotation of the first pair of torsion axles. A second pair of wheels is connected to a second cross-beam by a second pair of torsion axles such that rotation of the second cross-beam causes rotation of the second pair of torsion axles. An interconnecting bar is pivotally connected to the first cross-beam and the second cross-beam. A first frame rail and a second frame rail are connectable to the trailer frame. The first cross-beam and the second cross-beam are supported by and extend between the first frame rail and the second frame rail.

A trailer includes a trailer bed and a trailer tongue. The trailer bed includes a trailer frame, a body, a platform, and one or more sets of two or more wheels. The trailer tongue includes a tongue arm, a trailer hitch component coupled to the tongue arm, and one or more brackets coupled to the trailer frame via a bracket shaft. The trailer tongue is couplable to a vehicle hitch component. The trailer tongue is rotatable about an axis through the bracket shaft. The one or more brackets include one or more cut-outs configured to receive a locking component. The trailer tongue is securable via the locking component at a select angle relative to a ground surface. The trailer hitch component is positionable via the locking component at a select height relative to a height of the vehicle hitch component based on the angle relative to the ground surface.

An implement includes a hydraulic control to move rear wheels upward and downward. A hitch frame has a rear end pivotally connected to a front of the implement's frame about an upper hitch pivot axis and a front end connectable to a tractor drawbar. A tension link has a rear end pivotally connected to the front end of the implement about a lower hitch pivot axis located below and parallel to the upper hitch pivot, and a front end movably mounted to a front of the hitch frame. A front hydraulic cylinder moves the front end of the tension link forward and rearward. The hydraulic control activates the front hydraulic cylinder to move the tension link rearward as the rear hydraulic cylinder moves the rear wheels upward with respect to the implement frame, and to move the front end of the tension link forward as the rear wheels move downward.

Apparatuses, systems, and methods are disclosed for a trailer. An apparatus includes a trailer frame and a body coupled to the trailer frame. The body includes a monocoque structure that is molded from a plurality of material layers. The molded body includes at least one access and a storage compartment located towards a tongue of the trailer frame.

A vehicle includes a suspension that includes a front suspension and a rear suspension, a trailer hitch configured to removably connect to a tongue of a trailer, at least one front suspension transducer configured to generate a front suspension displacement signal, at least one rear suspension transducer configured to generate a rear suspension displacement signal, and an electronic control unit. The electronic control unit is configured to receive the front suspension displacement signal, receive the rear suspension displacement signal, and generate an alert of an excessive tongue weight condition based on one or more of the front suspension displacement signal and the rear suspension displacement signal.

Described herein is an axle assembly and method of fabrication thereof. The axle assembly includes an axle having a first geometric shape housed within an axle housing having a second geometric shape. A shock absorber is located between the axle and the axle housing. The shock absorber supports the axle within the axle housing and comprises a first material and comprises a multi-sided configuration. The first geometric shape and the second geometric shape comprising polygons.

A cap is provided for covering the threaded end of a removable spindle, having a cover with thread engaging tabs extending from a reservoir basin. The tabs include surface projections for retaining the cap to the spindle threads. The tabs are formed to fit within available slots of a slotted hex nut connected to the spindle. The cap includes a separately formed skirt or guard to make flexible surface contact with the torsion arm or spindle supporting structure. The skirt can include a sacrificial anode region to provide cathodic protection for the spindle threads and spindle retention nut. The skirt is removable from the cap so that the cap can be reused with a new skirt. The cap is formed to be used with existing spindle assemblies and to be reusable.

A suspension system is provided comprising at least one ride height valve, when engaged, that allows an air flow to engage a hydraulic control valve such that it initiates either extension or retraction of a hydraulic piston from a cylinder. Extension or retraction of the hydraulic piston causes a booster frame to be bias downwardly or upwardly, respectively. The ride height valve is engaged when a booster axle is at a predetermined distance from the frame.

A holding mount for a commercial vehicle trailer includes two side walls which extend along a vertical axis and which form an arrangement region for arranging the holding mount on a load-bearing element, the holding mount further including an insert part which has a connecting section and a reinforcing section, the connecting section forming the arrangement region, and the reinforcing section extending between the side walls along the vertical axis for the reinforcement purposes.
