<p>PURPOSE: To enable the rear-wheel steering, having high safety, by varying the transmission ratio between an oscillating stroke of an input lever and one lever of a four ink-type lever mechanism, in a rear wheel steering transmission for connecting a rear wheel steering device to a front wheel steering device at the variable transmission ratio. CONSTITUTION: In a rear wheel steering transmission 20 provided with an input lever 19 connected to an output part of a front wheel steering device through a push-pull cable, a four section link-type lever transmission having two levers 25, 26 capable of being oscillated around stationary axes 1, 2 is provided, and free ends of respective levers 25, 26 are hinged to a link part 29. One end of a connecting rod 31 is hinged to the link part 29, and the other end is hinged to a pressing rod 21 for forming an output part for driving a rear wheel steering mechanism. Moreover, one end of the lever 33 is hinged to the free end of the input lever 19 capable of being freely oscillated around a third stationary axis 3, and the other end of the lever 33 is hinged 35 to a connecting rod 36 hinged to the link part 29.</p> |
