Steering column for vehicle

摘要

Disclosed is a steering column for a vehicle. By the steering column, a manipulation convenience of the driver can be increased by performing a tilting or telescoping operation by using a pressure of air or oil without using an adjusting lever. Further, the number of components and manufacturing costs can be significantly reduced by easily adjusting an operating force of the actuator using a pressure of air or oil and an operating force of the lever according to the type of the vehicle.

主权项

1. A steering column for a vehicle, comprising:
an upper column having a hollow shape in which a steering shaft is installed and having a first hinge unit and a second hinge unit; a sliding bracket, opposite lateral parts of which are coupled to the first hinge unit to be slid lengthwise during a telescopic operation; a support bracket in which the sliding bracket is positioned and having first slots in a lengthwise direction thereof; a hinge plate having hinge holes coupled to the second hinge unit at one side thereof and having second slots at an opposite side thereof; a support shaft passing through the first slots and the second slots; a support tube coupled to an outer peripheral side of the support shaft to support both lateral parts of the sliding bracket and separated into a first part and a second part; and a lever, one end of which is coupled to the support shaft through the separated space of the support tube and an opposite end of which is coupled to an actuator, wherein the actuator is coupled to the sliding bracket to move the opposite end of the lever so as to apply a force to the first and second parts in opposite directions, and wherein in the actuator, a nozzle through which air or oil is introduced or discharged is installed at one side of a housing, a cylinder chamber communicating with the nozzle is formed in the housing, and a piston coupled to the lever is installed in the cylinder chamber.
