Rear wheel steering system for vehicles and vehicle comprising said system

摘要

The present invention relates to a rear wheel steering system for vehicles and vehicle comprising said system which allows rotating the rear wheels by means of a single actuator without increasing the suspended masses, comprising an independent suspension assembly (1) for each rear wheel (2), wherein each independent suspension assembly (1) comprises a suspension arm (3) having a first end (4) operatively connected to an axle (5) of a wheel (2), each suspension arm (3) having two second ends (6) which are articulated to a fixed part of the vehicle, each suspension arm (3) being able to rotate with respect to a rotation shaft (7) where the two second ends (6) of each suspension arm (3) are articulated; the system comprising a synchronisation device (12) comprising at least one synchronisation rod (12, 12', 12") the ends of which are connected by means of sliding carriages (8) to the rotation shafts (7), each sliding carriage (8) being operatively connected to the axle (5) of each wheel (2) by means of a transmission rod (11).
