Automobile active steering system with cycloidal-pin wheel mechanism

摘要

The invention discloses an automobile active steering system with a cycloidal-pin wheel mechanism, and aims at overcoming the contraction between light steering effort and flexibility. The automobile active steering system comprises a steering hand wheel (47), a steering shaft (52), a steering transmission shaft (48), a cycloidal-pin wheel type transmission mechanism (49), a rotary hydraulic valve (50), and a steering box (51). The steering hand wheel (47) is connected with an upper end of the steering shaft (52) by use of a spline pair, a lower end of the steering shaft (52) is connected with an upper end of the steering transmission shaft (48) by use of a universal joint, a lower end of the steering transmission shaft (48) is connected with a right end of an input shaft (21) of the cycloidal-pin wheel type transmission mechanism (49) by use of a universal joint.
