Patent DE-19510208-A1 (DE)
Inventor: RIEF KLAUS
IPC: B62D7/14
Filed: 1995-03-21
Abstract: A multiple axis steering system for vehicles comprises a steering gear (4) for a first steering axle (1) and a hydrostatic steering force transmission device with a master cylinder (5) for a second steering axle (2) adjusted via a slave cylinder (13). Oil leaks inside the steering system cause a kinematic fault between the first steering axle (1) and the second steering axle (2). The aim is therefore to ensure  automatic synchronisation of the steering system when the transmission hydraulics are not under load and the vehicle is moving in a straight line, and to keep the steering system design simple. To allow the use of a master cylinder (5) with uneven piston surfaces, it is proposed that check valves (22, 22A) with mutually opposing actions should be fitted in the transmission line (6) to prevent drift of the steering axle under the preload pressure of an accumulator (17). In addition, preloaded synchroniser check valves (23, 23A) are provided between the accumulator (17) and transmission lines (6, 7); these are opened by small differential pressures between the lines (6, 7) and can compensate for smaller seal leaks. Suction valves (24, 24A) are provided in addition between the accumulator (17) and transmission lines (6, 7); via those valves the transmission hydraulic system is pressurised with accumulator pressure.

Filed: 1996-09-02
Abstract: A bonding system (III) between the reinforcement system (II) and the outside layer (3) is fitted with a radial, axial or spiral two zone system (A,B), zone A being less adhesive than zone (B). In an elastomer hose with two reinforcing systems (I,II) and an interposed intermediate layer (2), with system (I) less expansive but of high chemical resistance where it faces the inner layer (1) of the sleeve, the bonding system between system (II) and layer (2) is in two radial, axial or spiral zones (A,B), again with zone (A) being less adhesive. The bonding system (III) should be integrally joined to the outer layer (3), the differentiated effect of the two zones (A,B) displaying itself directly on the reinforcing system (II). Otherwise, using a self-contained bonding system, this differentiated effect takes place directly in system (II) when this faces the side (4). The two-zone bonding system should extend right along the hose, zone (A) having an adhesive strength of maximum 0. 5 N/mm as against zone (B) of minimum adhesion 2 N/mm. The width of the more powerful zone (B) equals 10-30% that of the weaker zone (A), the two reinforcing systems (I,II) having interposed plastics or metal spiral close to the two systems and of high chemical resistance.
