Abstract

회전형 유로 전환 밸브의 슬리브를 피니온축에 일체화할 때 피니온축에의 부하시에서의 굽힘 변형을 방지하고, 원활한 밸브 작동을 얻을 수 있도록 한다. 스티어링 보디(7)내에서 조향 조작에 의해 회전하는 스터브축(2)에 조향륜 측 래크(5)에 맞물리는 피니온 톱니(3a)를 가지는 피니온 축(3)이 토션바(4)를 통해 상대적으로 회동 가능하게 연결된다. 이들 양 축의 단부 사이에 로터(11) 및 슬리브(12)를 가지는 회전형 유로 전환 밸브(10)가 설치된다. 슬리브를 피니온축에 일체적으로 설치함과 동시에 피니온축을 슬리브 양단부에서 베어링(21), (22)에 스티어링보디에 축 지지한다.When the sleeve of the rotary flow path switching valve is integrated with the pinion shaft, bending deformation under load on the pinion shaft is prevented and smooth valve operation can be obtained. The pinion shaft 3 having the pinion teeth 3a engaged with the steering wheel side rack 5 on the stub shaft 2 which is rotated by the steering operation in the steering body 7 turns the torsion bar 4. Relatively rotatably connected. A rotary flow path switching valve 10 having a rotor 11 and a sleeve 12 is provided between the ends of these two shafts. The sleeve is integrally installed on the pinion shaft, and the pinion shaft is axially supported by the steering body on the bearings 21 and 22 at both ends of the sleeve.
