This application is B are fastened to the bolt holes 119 through the frame block 130, the frame 110 and the frame block 130 according to the present exemplary embodiment are coupled.
Each of the wing portions 115 has through holes 116 formed therein, and the through holes 116 have threads formed therein. Bolts (not shown) are fastened to the threads and come into contact with the steering head 10 so as to be fixed in position.
The frame block 130 is fastened to a lower portion of the frame 110 by the bolts B and includes a body 131 surrounding the steering head 10 such that a lower portion of the steering head 10 is disposed therein when installed. Through holes 136 formed in a front portion 137 of the body 131 are formed at positions corresponding to the bolt holes 119 formed in the steering shaft penetrating portion 120 of the frame 110, and through holes 136 formed in a rear portion 132 of the body 131 are formed at positions corresponding to the bolt holes 119 formed in the wing portions 115 of the frame 110. The body 131 of the frame block 130 has a step such that the front portion 137 is higher than the rear portion 132.
When the frame 110 and the frame block 130 are coupled, the lower contact surface 132a of the rear portion 132 of the frame block 130 is tightly attached to a lower surface of the steering head 10, and pressure applied during fastening by the bolts B acts as normal force generating frictional force between the steering head 10 and the lower contact surface 132a, providing structural stability in fixing the steering shaft modifier 100 including the frame block 130.
The shaft 150 is inserted into the steering shaft installation portion 16 of the steering head 10 through a space portion 135 of the frame block 130. The shaft 150 includes the head portion 152 caught by the lower bearing installation portion 18 of the steering shaft installation portion 16 of the steering head 10, the body portion 151 passing through the steering shaft installation portion 16, and the connection portion 154 connected to the frame 110. The screw hole 155 is formed in an end portion of the connection portion 154 of the shaft 150 to which the bolt 177 of the shaft coupling part 170 is fastened.
The connection portion 154 has a thread formed on an outer surface thereof and screw-coupled to the internal hole 178 of the shaft coupling part 170. Namely, after the frame 110 is disposed above the steering shaft installation portion 16, the shaft 150 is inserted into the steering shaft installation portion 16, and the head portion 152 is rotated to fasten the connection portion 154 to the internal hole 178 of the shaft coupling part 170, thereby coupling the shaft 150 and the frame 110.
The head portion 152 of the shaft 150 has a sloped portion 153 sloped in a length direction of the shaft 150. The sloped portion 153 comes into contact with the lower bearing installation portion 18 of the steering shaft installation portion 16 and provides a push force based on rotation in order to fix the steering shaft modifier to the steering head 10.
As illustrated in
Meanwhile, a cross recess (not shown), or the like, may be formed in a lower surface of the head portion 152 of the shaft 150 to transmit rotary power, and the cross recess may allow the shaft 150 to be rotated through a tool, or the like.
Also, in the present exemplary embodiment of the present disclosure, since an additional member is not added to a lower portion of the shaft 150 and the shaft 150 is coupled through the frame block 130, a lower space of the steering head 10 may be secured, allowing a large wheel to be introduced.
For example, in the case of the related art, a block is disposed in a lower portion of a steering head, narrowing the space for a wheel to be introduced. In comparison, in the present exemplary embodiment of the present disclosure, dual-stability may be provided and a larger space may be secured through the frame block 130 coupled with the shaft 150 in the rear of the steering head 10, facilitating installation of a large wheel.
Also, in the present exemplary embodiment of the present disclosure, the steering shaft penetrating portion 120 is integrally formed in the frame 110 rather than being formed by coupling two members, eliminating the potential of dislocation due to assembling of the steering shaft penetrating portion 120. Namely, precise alignment is not required in the assembling operation, thus providing convenience to an operator in the assembling operation.
Namely, in the steering shaft modifier according to the exemplary embodiment of
The steering shaft modifier according to the present exemplary embodiment is similar to that of the exemplary embodiment of
As set forth above, according to exemplary embodiments of the present disclosure, a steering shaft modifier capable of fundamentally preventing distortion that may be generated in the new steering shaft due to mechanical tolerance in terms of manufacturing, being easily aligned, and being simply assembled may be provided.
Also, by transmitting impact applied to a lateral surface of a front side to a steering head, the steering shaft modifier may provide structural stability.
By facilitating alignment, or the like, a general user, rather than an expert, may easily install or detach the steering shaft modifier.
While exemplary embodiments have been shown and described above, it will be apparent to those skilled in the art that modifications and variations could be made without departing from the spirit and scope of the present disclosure as defined by the appended claims.
