Drive transmission group to a steer wheel of a vehicle

摘要

A drive transmission group to a steer wheel of a vehicle at least a drive chain ring associable to actuating means in rotation able to impart a rotary motion to the chain ring, at least a driven chain ring solidly associated in rotation coaxially to the steer wheel, at least a first intermediate chain ring and a second intermediate chain ring connected respectively to the drive chain ring and to the driven chain ring by means of respective flexible organs, a universal joint comprising a joint spider on a first arm of which the first intermediate chain ring is associated, rotatably with respect to an axis of the first arm, and on a second arm of which the second intermediate chain ring is associated, rotatably with respect to an axis of the second arm, wherein the first intermediate chain ring is concentric to the spider.

1. A drive transmission group (30) to a steer wheel (23) of a vehicle (10) which comprises:
at least a drive chain ring (31) associable to actuating means (32) in rotation able to impart a rotary motion to the chain ring (31),
at least a driven chain ring (33) solidly associated in rotation coaxially to the steer wheel (23),at least a first intermediate chain ring (34) and a second intermediate chain ring (36) connected respectively to the drive chain ring (31) and to the driven chain ring (33) by means of respective flexible organs (35, 36),a universal joint (50) comprising a spider (51) on a first arm (511) of which the first intermediate chain ring (34) is associated, rotatably with respect to an axis of the first arm (511), and on a second arm (512) of which the second intermediate chain ring (36) is associated, rotatably with respect to an axis of the second arm, wherein the first intermediate chain ring (34) is concentric to the spider (51), and wherein revolving organs (342) are interposed between the first arm (511) and the first intermediate chain ring (43).
