Description
The present invention relates to a telescopic device of a steering column for a vehicle. More specifically, the clamp and the slide device are formed even after a long time by forming a protrusion such as a washboard on a clamp and a fixed slide installed on the vehicle to adjust and fix the height of the handle of the vehicle. The steering force of the vehicle which can accurately transmit the rotational force of the rotating shaft by preventing the steering wheel from being easily moved by its own weight and preventing the rotating shaft and the transmission shaft from rotating or idling by its own weight so that the fixing force is not reduced. It relates to a telescopic device.
In general, the steering column is installed in the vehicle to adjust the height of the steering wheel of the vehicle was used by adjusting the height of the steering wheel using a device such as a slide and fixed using a handle.
In addition, the height of the handle is adjusted by using a slide device and the like, and the height of the handle is fixed by using an elastic device such as a spring, or by adjusting and fixing the height of the handle by using a device such as a gear.
However, the slide device used to adjust the height of the handle as described above, after a long time, the fixing force of the slide device is reduced, even if the user adjusts and secures the height of the handle using the slide device, the slide device is self-weighting There is a problem that the easy to move to the lower side or the locking device of the slide device is easily released.
In addition, the rotating shaft that transmits the rotational force of the handle is fixed by only one fixing device, and if a long time passes, the fixing force of the rotating shaft is reduced, there is a difference in the play of the rotating shaft and the rotation shaft does not properly transmit the rotational force of the handle there was.
The telescopic device of the steering column for a vehicle according to the present invention includes a pipe part consisting of a fixed pipe, an internal pipe, and a moving pipe, a fixed slide having a cutting surface, a slide groove, and a first protrusion, and fixed to the outside of the moving pipe of the pipe part. A cap having a C 'shape and a fixed portion formed on both sides of the cap and having a fixing groove corresponding to the slide groove and a second protrusion corresponding to the first protrusion are configured to move up and down simultaneously with the moving pipe along the slide groove. A rotating shaft consisting of a clamp, a coupling shaft, a central shaft, an insertion groove, and an insertion shaft formed with an insertion jaw, is coupled to the inside of the fixed pipe and the inner pipe of the pipe portion, and the insertion shaft of the rotation shaft is inserted into one side of the insertion groove. A first shaft formed with a corresponding coupling jaw and a coupling groove corresponding to the insertion jaw, and is integrally connected with the first shaft to the other side; A transmission shaft including a second shaft for transmitting rotational force of the rotation shaft to the wheel shaft of the vehicle, and a pin shaft coupled to the slide groove of the fixed slide and the fixed groove of the clamp on one side thereof, and a pin shaft formed with the first pin groove on the other side thereof. A handle shaft having a plurality of washers and an elastic member coupled to the bolt part and the pin shaft, the pin shaft being inwardly coupled, and a cutting surface and a contact surface formed at both sides to form a second pin groove having a long hole shape corresponding to the first pin groove; It consists of a handle portion consisting of a handle formed in close contact with the cutting surface of the handle shaft.
As described above, when the steering wheel height of the vehicle is adjusted, a protrusion such as a washboard is formed on a fixed slide and a clamp that moves and fixes up and down, so that the slide and the clamp do not slip by the protrusion, so that a long time is maintained. Since the fixing force of the slide and the clamp does not decrease even after passing, the handle is not easily moved by its own weight.
In addition, an insertion groove, a coupling jaw and a coupling groove corresponding to the insertion jaw are formed in the rotation shaft that transmits the rotational force of the handle and the rotation shaft, so that the rotation shaft and the transmission shaft do not rotate the wheels, thereby transmitting the rotation shaft and the transmission shaft. It is possible to accurately transmit the rotational force of the shaft to the engine, there is an advantage to prevent the damage of the rotation shaft and transmission shaft.
In addition, by forming an inner groove for fixing the bearing inside the fixed pipe and a bearing housing for fixing the bearing inside the moving pipe, the wear of the bearing can be reduced while rotating the rotating shaft and the transmission shaft more easily. have.
In addition, there is an advantage that the handle coupled to the handle shaft can be easily rotated by forming a free cutting surface on the handle shaft to fix the position of the moving pipe or the rotating shaft.
In addition, by forming an elastic member of the urethane material to the handle for adjusting and fixing the height of the handle by using the handle, there is an advantage of preventing the damage of the handle by the elastic member and does not reduce the fixing force of the handle.
