On each side of the vehicle front and rear wheels actuate respective hydraulic displacer units 1 which are connected to a common hydraulic accumulator 7. Both rear wheels are connected by a torsion rod 10, the pre-load of which is variable by the action of a crank 11 actuatable by an electric motor 13. The latter is controlled by a switch 14 controlled by an electric or hydraulic device 15 sensitive to changes in vehicle height. The device 15 has a time delay to prevent it being affected by the rapid changes in height due to changes in dynamic load. In a modification (Figs. 3-5, not shown), the torsion rod 10 is replaced by a leaf spring, the central anchoring point of which is carried by a crank rotatable by the motor 13. The accumulators 7 are replaced by flexibility of the connecting conduits 8. Specifications 813,259 and 826,687 are referred to.

TRAILING ARM SUSPENSION

Vehicle suspension system

A structurally efficient vehicle suspension system capable of being isolated from the main vehicle structure by being housed within a vehicle's wheel thereby reducing risks of injury during a crash and permitting advantageous redesign of suspension geometry. By rotating the suspension link pivot axes approximately 90 degrees in a counterclockwise direction when compared with the positioning of traditionally known wishbone suspension systems, the upper and lower suspension links for each vehicle wheel are relocated to run essentially parallel to the axis of travel of that wheel. Consequently, for each wheel the virtual longitudinal link length runs parallel with the axis of travel of the wheel indicated by the arrow and virtual swing axle length runs perpendicularly to virtual longitudinal link length. However, the upper link pivot axis and the lower link pivot axis now run parallel to virtual swing axle and their convergence point defines its length.

Controlled single wheel block for trailer

FIELD: mechanic. SUBSTANCE: a single wheel block designed with the possibility of installation on the body of a vehicle, contains a wheel frame, which serves as a support for the suspension mechanism and the wheel assembly installed on the suspension mechanism. The suspension mechanism contains a Z-shaped link consisting of three levers connected end to end so that they can rotate. The suspension mechanism is fixed to the wheel frame so that the mechanism can be rotated, and a damping device absorbs the suspension mechanism vibration. The wheel suspension hinge support intended for the installation between two rotatable elements contains a cylindrical bushing support limiting the central shaft and having open ends with curved belts. The bushing support is located in a bored hole of the first rotational element. This bushing support supports the axle passing through the flanges with holes in the second rotational element. The flanges are located at each side of the bored hole and the bushing support. The flange holes have curved surfaces for reception of the mating curved bushing support belts. EFFECT: increased manoeuverability, increase effective load, lower tyre wear. 28 cl, 18 dwg ÐÎÑÑÈÉÑÊÀß ÔÅÄÅÐÀÖÈß (19) RU (11) 2 324 616 (13) C2 (51) ÌÏÊ B62D B62D B60G B60G 5/20 (2006.01) 13/04 (2006.01) 7/00 (2006.01) 17/00 (2006.01) ÔÅÄÅÐÀËÜÍÀß ÑËÓÆÁÀ ÏÎ ÈÍÒÅËËÅÊÒÓÀËÜÍÎÉ ÑÎÁÑÒÂÅÍÍÎÑÒÈ, ÏÀÒÅÍÒÀÌ È ÒÎÂÀÐÍÛÌ ÇÍÀÊÀÌ (12) ÎÏÈÑÀÍÈÅ ÈÇÎÁÐÅÒÅÍÈß Ê ÏÀÒÅÍÒÓ (21), (22) Çà âêà: 2005127038/11, 28.01.2004 (72) Àâòîð(û): ÄÝÉÂÈ Ãàðò Áàððèíãòîí (AU) (24) Äàòà íà÷àëà îòñ÷åòà ñðîêà äåéñòâè ïàòåíòà: 28.01.2004 (73) Ïàòåíòîîáëàäàòåëü(è): ÑÒÈÐÀÁË ÓÈË ÑÈÑÒÅÌÇ ÏÒÈ ËÒÄ (AU) R U (30) Êîíâåíöèîííûé ïðèîðèòåò: 28.01.2003 AU 2003900336 (43) Äàòà ïóáëèêàöèè çà âêè: 27.07.2006 (45) Îïóáëèêîâàíî: 20.05.2008 Áþë. ¹ 14 2 3 2 4 6 1 6 (56) Ñïèñîê äîêóìåíòîâ, öèòèðîâàííûõ â îò÷åòå î ïîèñêå: WO 01/53141 A1, 27.07.2001.
