KR950029126A - Hanger structure of bicycle - Google Patents

Abstract

The hanger structure of the bicycle according to the present invention combines an inclined surface composed of a tapered surface or a spherical surface formed at one end of the crankshaft assembly with a corresponding inclined surface of the hanger, and screws the other end of the sleeve to the hanger corresponding thereto. Secure with glue, and screw on the hanger only on one side. Thereby, the effect of the deformation of the female screw according to the thermal deformation of the lugs on the left and right of the hanger part can be influenced by the rotation of the crankshaft, and the female screw on the left and right lugs of the hanger part can be processed either or both. The screwing operation for mounting the crankshaft can be completed in only one place, so that the crankshaft can be easily joined to improve workability, and a hanger structure of a motorcycle without the rotational state of the crankshaft can be obtained.
