A vehicle height control system and method of increasing a vehicle height of a vehicle having a vehicle body and at least one axle assembly. The vehicle height control system includes a pressurized fluid supply system configured to supply a pressurized fluid, and a plurality of air springs provided to elastically support at least one section of the vehicle body of the vehicle above at least one axle assembly of the vehicle and configured to adjust the vehicle height of such sections of the vehicle body relative to a ground surface in response to the supply and discharge of the pressurized fluid. A control assembly of the vehicle height control system has a piston unit fluidically interconnected with the pressurized fluid supply system via a first control valve and is operable to adjust the vehicle height by adjusting a second control valve interposed between the pressurized fluid supply system and the air springs. A controller is configured to receive user input indicative of a Vehicle height adjustment operation desired by a user and to adjust the vehicle height by controlling the control assembly based on the user input.

Disclosed is a load detection device and method using the same. In one example, the device includes a height-level measuring unit configured to determine a height level of a vehicle and to generate at least one height-level signal that characterizes the height level. A position-measuring unit is configured to determine the position of the vehicle relative to the mid-point of the earth and to generate at least one position signal that characterizes the vehicle position. An evaluation unit is coupled to the height-level measuring unit and to the position-measuring unit. The evaluation unit is configured to determine a mass of a load of the vehicle, taking into account the height-level signal(s) and the position signal(s). The device can be used to determine the mass of the load, which may include a number of persons.

A load carrying vehicle including: a chassis; a load carrying container connected to the chassis; a plurality of wheels; a suspension arrangement coupling the wheels to the chassis; wherein the suspension arrangement is configured to controllably lower the container such that the container makes contact with at least two wheels.

A telehandler comprising: a chassis; an axle supporting the chassis; a pivotal connection between the axle and the chassis; and a chassis positioning system. The pivotal connection is configured to enable rotation of the chassis relative to the axle for varying a chassis-axle tilt angle defined between a longitudinal axis of the axle and the chassis. The chassis positioning system comprises: a chassis angle sensor configured to measure an angular position of the chassis relative to gravity; an actuator configured to rotate the chassis relative to the axle at the pivotal connection; and a control system configured, in a first mode, to control the actuator to thereby control the chassis-axle tilt angle based on the measured angular position of the chassis.

Methods are described that perform a dispatched consumer-to-store return or swap logistics operation for an item being replaced using a modular autonomous bot apparatus assembly and a dispatch server. The method begins with receiving a return operation dispatch command that includes identifier information, transport parameters, and designated pickup information for the item being replaced/returned, along with authentication information related to an authorized supplier of the item being replaced. Modular components of the bot apparatus are verified to be compatible with the dispatched logistics operation. The MAM then autonomously causes the bot apparatus to move to the designated pickup location, notifies the authorized supplier of an approaching pickup, receives supplier authorization input to permissively allow access to a payload area within the bot apparatus, monitors loading as the item being replaced is received along with return documentation, and then autonomously causes movement of the bot apparatus back to the origin location.

A machine includes a first cylinder coupled to a first wheel and a second cylinder coupled to a second wheel. A first proportional dampening valve fluidly connects to the first cylinder and a second proportional dampening valve fluidly connects to the second cylinder. First accumulators are fluidly connected to the first cylinder and the first proportional dampening valve, and second accumulator(s) are fluidly connected to the second cylinder and the second proportional dampening valve. Additionally, a first proportional flow control valve fluidly connects to the first cylinder and a second proportional flow control valve fluidly connected to the second cylinder. An electronic control module (ECM) communicatively couples to the first proportional flow control valve and the second proportional flow control valve to adjust a ride height of the first wheel via the first cylinder and a ride height of the second wheel via the second cylinder.

A suspension arrangement for a vehicle includes a piston for supporting a flexible bellows assembly of the suspension arrangement, said piston having a first portion connectable to the flexible bellows assembly and a second portion connectable to a wheel axle, said piston further having an outer side and an inner side, and wherein said suspension arrangement further comprises a mounting structure for positioning an insertable sensor device toward the flexible bellows assembly, said mounting structure extending at least from the outer side to the inner side and having an outer opening for receiving the insertable sensor device from an outside of the piston.

An air-suspension module for a rigid axle including an air-bellows mount and an air-bellows module supported on the air-bellows mount in the operational state of the air-suspension module, the air-bellows module having an air-suspension bellows designed to change its shape and a supporting body connected to the air-suspension bellows, one of the components of the air-bellows mount and the supporting body having a coupling projection protruding along a virtual projection path, which engages with a coupling recess formed at the respectively other component along the projection path, a translatory relative movement of the supporting body being physically limited relative to the air-bellows mount, orthogonally with respect to the projection path and in a direction along the projection path; one of the components of the air-bellows mount and the supporting body having a latching body and the respectively other component of the air-bellows mount and the supporting body having a latching recess such that the latching body is in a form-locking latching engagement with the latching recess, so that a translatory relative movement of the supporting body relative to the air-bellows mount is physically limited in the two opposite directions along the projection path.

An electrified vehicle, comprising a chassis having a frame, a first tractive element, and a first suspension system coupled with the first tractive element and the chassis. The first suspension system may comprise a first knuckle coupled with the first tractive element, and a first strut-damper coupled with the first knuckle and the chassis, the first strut-damper extending between the chassis and the first knuckle. The first suspension system may also include a first control arm coupled with the first knuckle and the frame member, and a torsion bar coupled with the chassis at a first end of the torsion bar. The torsion bar may extend in a direction substantially parallel with the frame member, where the torsion bar may be configured to support a portion of a mass of the electrified vehicle in response to displacement of the first tractive element relative to the chassis.

A primary air suspension system with the reliability of a secondary air suspension system by guaranteeing a minimum pressure in the air spring through a simple mechanical residual pressure valve. The residual pressure valve is set to the air spring pressure required to hold the rear of the unloaded pickup truck at the designed ride height if any of the components (compressor, tank, valves, air lines, Schrader valve, or electronic controller) failure.
