STEERING COLUMN FOR VEHICLE
The present disclosure relates to a steering column for a vehicle. The present disclosure provides a steering column for a vehicle that includes: an input shaft connected with a steering wheel at one end portion thereof, wherein a torque sensor is coupled to the outer circumferential surface of the input shaft; an output shaft having a worm wheel coupled to the outer circumferential surface of one end portion thereof that is connected with an opposite end portion of the input shaft; an output shaft bearing coupled to the outer circumferential surface of the output shaft so as to be located adjacent to the worm wheel; and a support member interposed between the outside of the outer race of the output shaft bearing and a gear housing to support the output shaft bearing in the radial direction.
1 . A steering column for a vehicle, comprising:
an input shaft connected with a steering wheel at one end portion thereof, wherein a torque sensor is coupled to the outer circumferential surface of the input shaft;
an output shaft having a worm wheel coupled to the outer circumferential surface of one end portion thereof that is connected with an opposite end portion of the input shaft;
an output shaft bearing coupled to the outer circumferential surface of the output shaft so as to be located adjacent to the worm wheel; and
a support member interposed between the outside of the outer race of the output shaft bearing and a gear housing to support the output shaft bearing in the radial direction.
2 . The steering column of claim 1 , wherein the outer race of the output shaft bearing and the support member are axially supported by a bearing bracket coupled to the outside of the gear housing.
3 . The steering column of claim 2 , wherein the inner race of the output shaft bearing is axially supported by a lock nut coupled to the outer circumferential surface of the output shaft.
4 . The steering column of claim 3 , wherein the support member has a ring shape and is cut away at one side thereof.
5 . The steering column of claim 4 , wherein the support member has a large diameter portion configured to have an enlarged diameter and to make contact with the bearing bracket.
6 . The steering column of claim 5 , wherein the gear housing has a mounting recess formed therein into which the support member is inserted, and an enlarged diameter portion is formed in the mounting recess, the large diameter portion being inserted into, and axially supported by, the enlarged diameter portion.
7 . The steering column of claim 1 , wherein the input shaft has an input shaft bearing coupled to the outer circumferential surface thereof so as to be located adjacent to the torque sensor.
8 . The steering column of claim 7 , wherein the outer race of the input shaft bearing is axially supported by a step of the gear housing.
