Abstract From the Canadian patent

This unit is provided with two hydropneumatic jacks having parallel vertical axes X-X and comprising bodies adapted to be rigidly connected by a plate and mounted slidably on rods fixed to the chassis of the vehicle. The plate is sufficiently wide to allow if desired the passage of a transmission for the corresponding wheel. This arrangement improves the guiding of the wheels by holding them in fixed planes and enables them if desired to be made into driving and/or steered wheels.
