Abstract
A vehicle steering column may include a hollow lower tube coupled and fixed to a mounting bracket, a hollow middle tube coupled to an inner side of the lower tube and sliding in an axial direction, a hollow upper tube having an inner side to which a steering shaft is rotatably coupled and an outer side to which the middle tube is coupled to slide in the axial direction, and a tube support member coupled to an inner side of a lower end portion of the lower tube and supporting lower end portions of the middle tube and the upper tube.
Claims20
A vehicle steering column comprising:
- a lower tube fixed to a mounting bracket;
- a middle tube slidably coupled to an inner side of the lower tube and configured to be slidable relative to the lower tube in an axial direction of the vehicle steering column;
- an upper tube having an inner side to which a steering shaft is rotatably coupled and an outer side to which the middle tube is coupled, the upper tube configured to be slidable in the axial direction of the vehicle steering column;
- and
- a tube support member coupled to an inner side of a lower end portion of the lower tube and configured to support lower end portions of the middle tube and the upper tube.
A vehicle steering column comprising:
- a lower tube fixed to a mounting bracket;
- an upper tube having an inner side to which a steering shaft is rotatably coupled and an outer side to which the lower tube is coupled, the upper tube configured to be slidable in an axial direction of the vehicle steering column;
- and
- a tube support member coupled to an inner side of a lower end portion of the lower tube, configured to support a lower end portion of the upper tube, and having a hole in which the steering shaft is disposed, wherein an inner diameter of the hole of the tube support member is smaller than an inner diameter of the upper tube such that the lower end portion of the upper tube is supported by the tube support member.
A vehicle steering column comprising:
- a lower tube fixed to a mounting bracket;
- an upper tube having an inner side to which a steering shaft is rotatably coupled and an outer side to which the lower tube is coupled, the upper tube configured to be slidable in an axial direction of the vehicle steering column;
- and
- a tube support member coupled to an inner side of a lower end portion of the lower tube, configured to support a lower end portion of the upper tube
- wherein the lower end portion of the lower tube has a cylinder portion through which the steering shaft passes, the cylinder portion has a flange radially extending from an inner surface of the cylinder portion, and the tube support member is coupled to the flange of the cylinder portion,
- wherein the tube support member includes:
- a ring-shaped outer support portion configured to support an outer surface of the upper tube;
- a ring-shaped inner support portion disposed in the ring-shaped outer support portion and configured to support an inner surface of the upper tube;
- a bulkhead having a shaft hole through which the steering shaft passes and connecting the ring-shaped outer support portion and the ring-shaped inner support portion;
- and
- a flange fastening portion extending axially from the bulkhead and having a groove into which the flange of the cylinder portion of the lower tube is inserted.
