FIELD: transport engineering; bicycles. ^ SUBSTANCE: invention relates to fastening of bicycle pedals on shaft of crank. Two bearing units 3, 4 are arranged on shaft 1, with hollow housing of pedal 5 fitted on bearing units. One of bearing units, namely unit 3, is mated with surface of crank 2. thread is made on inner surface of hollow housing of pedal 5 in which hollow bolt 6 is fitted to serve as stop for other bearing unit 4. Nut 7 thrusts bearing unit 4 from outer side of shaft 1. Thrust end face surface of hollow bolt 6 is arranged at distance equal to approximately 1/4 of length of housing of pedal 5 from its axis of symmetry along shaft 1 in outward direction. ^ EFFECT: decreased deformation of pedal shaft owing to reduction of arm creating bending moment, facilitated assembling of pedal. ^ 3 dwg |
