Patent CA-2161619-A1 (CA)
Inventor: ENDE BERND
IPC: F16L53/32
Filed: 1995-10-27
Abstract: The preheating of hydraulic systems is prior art. It is generally done by operating the system without load until the prescribed minimum temperature is attained. However, in the known types of preheating circuits the operating elements (hydraulic cylinders) are not included. The invention relates to an arrangement in which the operating elements are included in the heating circuit.Appropriate circuits are provided for the various operating states of the hydraulic cylinder, i.e. "neutral", "retract piston rod" and "extend piston rod". The provision of an additional passageway in the piston rod through which the hydraulic oil can pass into the hydraulic cylinder is an essential feature by means of which the oil can circulate without the application of pressure while the system is in the neutral operating state. By using the invention, it is possible to preheat hydraulic circuits in the neutral, non-operating state, thusavoiding damage to the operating elements, increasing the lifetime of the wear parts and guaranteeing reliable operation of the hydraulic system. The inventionis suitable in particular for use in conveyor systems operating in cold regions.

Title: Steering system for working vehicle and the method thereof
Inventor: MOMOSE SHINROKU
IPC: B62D113/00
Filed: 1995-11-30
Abstract: A steering system and method of a mowing vehicle comprise left and right rear wheels rotating about a king pin for steering the vehicle, an Ackermann steering mechanism for steering these left and right rear wheels and a rear axle housing swingably connected with the vehicle about a yawing axis in a horizontal plane by use of a hydraulic cylinder.          When the vehicle makes a U-turn for example to the right during the mowing work, the rear axle housing is fully swung to the left in the horizontal plane by a specified angle and fixed therein  while the left and right rear wheels are held at the neutral position. After the rear axle housing is fixed at that angle, the left and right rear wheels are rotated about the king pin to the left and then the vehicle makes a U-turn to the right. When the vehicle finishes to turn, the left and right rear wheels are rotated about the king pin to the right until the neutral position and then the rear axle housing is swung in the horizontal plane back to the right until the neutral position. When the vehicle makes a U-turn to the left, the same operations are carried out.  Since the rear wheels are steered after the rear axle housing is swung in the horizontal plane and fixed, the vehicle can make a U-turn with a minimal turning radius,  retaining the Ackermann steering condition and the lawn can be prevented from being damaged by the wheels.
