STEERING SYSTEM OF HEAVY FIFTH-WHEEL TRAILER-TRAIN Russian patent published in 2007 - IPC B62D13/04 

FIELD: transport engineering.

SUBSTANCE: proposed steering system of heavy trailer-train has steering linkages of prime mover and trailer coupled with steerable wheels and actuating hydraulic cylinder. Rod of actuating cylinder is mechanically coupled with spool hydraulic distributor with power hydraulic cylinder mechanically coupled by tie-rods with steering linkage of trailer. System contains also additional hydraulic cylinder secured on prime mover connected by rod with lever coupled with steering linkage. Additional hydraulic cylinder is hydraulic coupled with space of actuating hydraulic cylinder. Reservoir to make up hydraulic system with closing cocks is included additionally into main line connecting additional hydraulic cylinder with actuating hydraulic cylinder. Invention simplifies design providing setting parameter of turning of steerable wheels of semitrailer as a function of angle of turning of steerable wheels of prime mover and provides multipurposeness of trailer-trains owing to possibility of coupling of steerable semitrailers with typical fifth-wheel prime movers and specialized prime movers with typical semitrailers.

EFFECT: simplified design, increased multipurposeness of trailer-train members.
