A wheel suspension arrangement is provided for a vehicle having a longitudinal direction, a transverse direction and a vertical direction. The wheel suspension arrangement includes a wheel holder for supporting a vehicle wheel. A first vertical end region of the wheel holder is pivotally attached to a vehicle support structure by a rigid control arm and a second vertical end region of the wheel holder is attached to the vehicle support structure by a leaf spring. A longitudinal direction of the leaf spring is arranged substantially in the transverse direction of the vehicle. The leaf spring is pivotally attached to the vehicle support structure at a transverse center region of the vehicle, and a center of the leaf spring in the transverse direction is located vertically offset from a pivotal attachment location of the leaf spring. The pivotal attachment location of the leaf spring is vertically offset towards the side of the rigid control arm.

Method for venting a pneumatic system of a vehicle, pneumatic system and vehicle Method for venting a pneumatic system (1) of a vehicle, the pneumatic system (1) comprising an air compressor (4), a pneumatic circuit (2), an air pressure management system (6) in communication with the air compressor (4) and the pneumatic circuit (2), and a control unit, the method comprising: while pressure in the pneumatic circuit (1) is less than a cut-out pressure, supplying the pneumatic circuit (2) with compressed air from the air compressor (4) operated at an operating speed through the air pressure management system (6), once pressure in the pneumatic circuit (2) reaches the cut-out pressure, lowering pressure in the pneumatic circuit (2) to a target pressure, the air compressor (4) being operated at at least one deflating speed lower than the operating speed, the deflating speed being non null, after pressure in the pneumatic circuit (2) has reached the cut-out pressure, releasing compressed air in the air pressure management system (6) to the outside environment.

An independent suspension for vehicles, in particular for transporting people and/or materials, including a hub defining a rotation axis of the wheel of the vehicle, an electric motor, operatively connected to the hub and configured to rotate the hub and a support element operatively connected to the hub and developing, with a planar shape, along its own main development direction transverse to the rotation axis of the wheel. The support element is arranged below the hub and the electric motor. The electric motor develops within a containment volume defined at least partially by the support element.

A mechanically actuated level control valve device for a commercial vehicle with an air suspension system is a level control valve and comprises a drive element that can be mechanically coupled to a vehicle wheel or axle. A valve element and a counter valve element have a first relative position, wherein the port for the air suspension bellow is closed, a second relative position, wherein the port for the air suspension bellow is connected to the port for the aeration device, and a third relative position, wherein the port for the air suspension bellow is connected to the port for the deaeration device. The valve element is coupled to a rotatable driveshaft of the level control valve by a drive mechanism. An integrated actuator changes the relative position of the valve element and the drive element or the relative position of the counter valve element and a valve housing.

A vehicle includes an outside sensor configured to acquire information on an outside circumstance of the vehicle, a vehicle height adjusting device configured to adjust a vehicle height, and a control device configured to control the vehicle. The control device is configured to control the vehicle height adjusting device such that the vehicle height becomes a vehicle height corresponding to a platform condition at a predetermined stop position when the vehicle stops at the predetermined stop position. The control device is configured to control the vehicle height adjusting device based on a height of an obstacle such that the obstacle does not interfere with the vehicle when the obstacle is detected at the predetermined stop position by the outside sensor.

A method for controlling the level of an air-suspended motor vehicle includes determining, by a sensor system, at least one of the speed of travel or the actuation state of a parking brake, measuring, if at least one of the speed of travel has undershot a minimum speed of travelor the parking brake has been actuated, the actual level in the region of each air spring bellows, comparing the measured values for the actual level with the predetermined setpoint level, determining an actual level value of an air spring bellows having the greatest deviation from the setpoint level, and expanding, for the air spring bellows having an actual level having the greatest deviation from the setpoint level, the tolerance band by at least one of increasing the upper tolerance limit thereof to a corrected upper tolerance limit or lowering the lower tolerance limit thereof to a corrected lower tolerance limit.

A side structure of a bus includes a skirt rail. Window fillers are connected to the skirt rail at lower ends, extend in an upper side, and are arranged from a front to a rear with a predetermined interval. A waist rail extends from the front to the rear with a predetermined distance in the upper side of the skirt rail and is engaged with each of the window fillers. A first region includes a first member connecting the waist rail and the skirt rail and a second member connecting the upper part of the first member and the lower end of the window filler. A second region includes a third member connecting the waist rail and the skirt rail and a fourth member connecting the upper of the third member and the lower part of the window filler.

A system for level regulation of a driver's cab of a commercial vehicle relative to a chassis of the vehicle includes a spring-loaded bearing in order to support the driver's cab in a sprung manner on the chassis of the vehicle; a distance sensor device arranged to record relative movements and/or a distance between the driver's cab and the chassis of the vehicle; and a control device that is arranged for variable control of the spring-loaded bearing, wherein signals of the distance sensor device are used to control the spring-loaded bearing. The spring-loaded bearing can be adjusted to a first height position (h1), so that the distance between the driver's cab and the chassis of the vehicle is controlled by the control device to a first target distance. The spring-loaded bearing can be adjusted to at least one second height position (h2), so that the distance between the driver's cab and the chassis of the vehicle is controlled by the control means to a second target distance. The control means device adjusts the spring-loaded bearing to the first height position (h1) or to the at least one second height position (h2) depending at least on a parameter relating to a driving route and/or a vehicle state.
