The invention relates to a hub reduction gear () for a driving wheel () of a wheeled vehicle with a planetary gear unit, which has a sun gear () connectable to a drive shaft (), a carrier () for planet gears (), which are in mesh with the sun gear (), and a ring gear () being in mesh with the planet gears (). The planet gear carrier () and the ring gear () are configured to be alternately connected to the driving wheels () of the vehicle and being alternately connectable to a body-fixed part (). The invention also relates to a driveline for a multi shaft, wheel supported vehicle with a hub reduction gear () of planetary gear type at the driving wheels of the vehicle, wherein the planet gear carrier and the ring gear of the planetary gears on at least one side of the vehicle are configured to be alternately connected to the driving wheels of the vehicle and being alternately connectable to a body-fixed part of the vehicle.

Hub reduction gear and driveline for a wheeled vehicle and multi-shaft wheeled vehicle

Wheel suspension for a wheeled vehicle, with a lower rocking lever () with an inner end being movably connected to a vehicle frame () via a lower arm part () of a double armed rocker () which is pivotable about a substantially horizontal axle () in the vehicle frame, and with an outer end being articulately attached to a lower part of a wheel hub (), and an upper support arm () with an outer end being articulately attached to an upper end of the wheel hub (), and with an inner end, being articulately connected to the vehicle frame (). The upper support arm () is connected to an upper arm part () of the double armed rocker () via a coupling link (), which is articulately connected to the upper support arm () as well as the upper arm part () of the double armed rocker (), wherein the lower rocking lever () has an inclination obliquely downwardly outwardly from the vehicle frame () in a neutral position of the wheel hub (). A hydro-pneumatically combined spring acting and damping member (), which comprises a hydraulic piston-cylinder device () and a gas spring () communicating therewith via restriction members is with its cylinder articulately connected to the vehicle frame (), while the outer end of the piston stem () of the piston-cylinder device is articulately connected to the upper support arm ().

Wheel suspension for wheeled vehicles

A suspension device has in- and out-configurations for use with a vehicle, including means for damping and/or spring action, the damping and/or spring action being controllable, wherein the controllability of the damping and/or spring action includes a locked or substantially locked state in the out-configuration. A method of using the suspension device with a vehicle is also provided.

Suspension device and method for use with a vehicle

Wheel suspension () for a wheeled vehicle, comprising at least one lower, wheel-carrying radius arm () with an inner end, which is designed for fastening so that it can pivot about a substantially horizontal axis in a vehicle frame (), and an outer end, which is pivotally fastened to a lower part of a wheel hub (), and at least one upper support arm (), one end of which is fastened to an upper part of the wheel hub (), and the other end of which is pivotally connected to the vehicle frame (). The inner end of the lower radius arm () is designed for pivotal connection to the vehicle frame () by way of a lower arm part () of a double rocker arm (), swiveling about a substantially horizontal axis (), whilst the upper support arm () is pivotally connected to an upper arm part () of the double rocker arm () via a connecting link (), which is pivotally connected to the upper support arm () and to the upper arm part () of the double rocker arm ().
