Steering apparatus

摘要

A steering wheel is coupled to a steering gear via a steering shaft, an intermediate shaft, a clutch input shaft and a clutch output shaft. When viewed in a vehicle transverse direction, a tilt angle α of the clutch input shaft relative to the horizontal plane is set to be smaller than a tilt angle β of the intermediate shaft relative to the horizontal plane. A steering column is supported by a vehicle body via a tilt pivot for adjusting a tilt position. Even when the steering column is located at any tilt position, the relationship of α<β is set to be maintained when viewed in the vehicle transverse direction. The center position of a universal joint between the steering shaft and the intermediate shaft is misaligned with the center position of the tilt pivot when viewed in the vehicle transverse direction.

主权项

1. A steering apparatus comprising:
a steering wheel that is manipulated by a driver; a steering shaft of which one end is coupled to the steering wheel; a steering column supported by a vehicle body and configured to rotatably support the steering shaft; an intermediate shaft of which one end is coupled to another end of the steering shaft via a universal joint; a clutch input shaft of which one end is coupled to another end of the intermediate shaft via another universal joint; a clutch output shaft of which one end is disposed to face another end of the clutch input shaft; a clutch fixed to the vehicle body and configured to connect and disconnect the clutch input shaft and the clutch output shaft; a steering gear configured to convert rotational movement of the clutch output shaft into linear movement to steer vehicle wheels; a drive mechanism configured to apply a drive force to a power transmission system on a clutch output shaft side so as to steer the vehicle wheels in a state where the clutch is disconnected; and a bracket configured to fix the clutch to the vehicle body and to restrict placement angles of the clutch input shaft and the clutch output shaft, wherein a tilt angle of the intermediate shaft relative to a horizontal plane is set to be larger than a tilt angle of the clutch input shaft relative to the horizontal plane when viewed in a vehicle transverse direction, and the bracket is disengaged from the vehicle body when a predetermined impact load in a vehicle longitudinal direction is input to the steering gear.
