Abstract
The utility model relates to a lightweight bicycle pedal, which comprises a pedal mandrel and a pedal body. A first rotating assembly is assembled between the inner side end of the pedal mandrel and a shaft hole of the pedal body, a second rotating assembly and a third rotating assembly which can be used as bearings are arranged between the outer side end of the pedal mandrel and the shaft hole of the pedal body, an inner ring inside wall and an outer ring outside wall of the second rotating assembly are respectively abutted and limited via inside wall surfaces of a limiting wall at the outer side end of the pedal mandrel and a limiting wall inside the shaft hole at the outer side end of the pedal body, an outer ring inside wall of the third rotating assembly is abutted and limited via an outside wall surface of the limiting wall of the pedal body, and an inner ring outside wall of the third rotating assembly is abutted and packed via a block nut at the outer side end of the pedal mandrel. The outer side end of the shaft hole is not required to be provided with conventional outer thread and a screwing end cover so that the thickness of the wall of the shaft hole can be reduced, and the two bearings can increase load bearing strength and shorten length of the pedal mandrel, thereby integrally meeting a lightweight requirement.
Description
Technical field
The utility model system is relevant with a kind of member voluntarily, more detailed it, be meant a kind of lightweight bicycle pedal especially.
Background technology
The Regular Bicycle pedal comprises a pedal spindle, and the movable pedal body of a pivot on pedal spindle that wear, for pedal body still can be rotated when bearing treadle effort swimmingly, pearl nido bearing is installed between pedal spindle and pedal body in early days mostly, then general at present with ball bearing of main shaft.
Existing pedal, highway car contest pedal particularly, because the rider can link knot by the bayonet unit active card between sole and pedal, therefore, its pedal area, particularly axial width can dwindle, relatively, can adopt short pedal spindle, in addition, most of pedals all adopt long pedal spindle, but owing to adopt long pedal spindle, its pedal force active position has the long arm of force usually, therefore, can produce bigger moment of deflection, when this moment of deflection sees through the bearing transfer function during in pedal spindle be installed in pedal spindle medial extremity and external side end place, relatively, these bearings, the bearing of external side end particularly, also can bear bigger load application force, be damaged, the smoothness that influence pivots for avoiding bearing, usually ball bearing of main shaft can be selected to install by pedal spindle external side end place, and ball bearing of main shaft or self lubricating bearing then can freely be selected to adopt by the medial extremity place.
As shown in Figure 1, promptly disclose a kind of axle pivot structure of existing common pedal 10, its pedal spindle 11 external side ends are equipped with a ball bearing of main shaft 12, the interior ring 121 and outer shroud 122 madial walls of this ball bearing of main shaft 12 abut against respectively and are positioned the limited wall 111 that pedal spindle 11 periphery walls are step shape, and pedal body 13 axis holes 131 internal perisporiums are on the limited wall 132 of step shape, its lateral wall then can be subjected to the block nut 14 of a screw lock on pedal spindle 11 external side end external screw threads 112 respectively, and the end cap 15 of a screw lock on pedal body 13 axis holes 131 internal screw threads 133 replaced the location, by this, this pedal spindle 11 to each other can be by the movable pivot in axial limiting ground with pedal body 13.
The axle pivot structure of above-mentioned pedal 10, the ball bearing of main shaft 12 of external side end particularly, because the lateral wall of interior ring 121 must be replaced spacing by end cap 15, therefore, axis hole 131 external side ends of its pedal body 13 just must fix for end cap 15 screw locks by processing and fabricating internal screw thread 133, therefore, for making the above-mentioned internal screw thread 133 of pedal body 13 machine-shaping successfully, its pedal body 13 essential axis hole 131 wall walls of reserving adequate thickness cause its reduced down in thickness to be restricted, and weight is difficult to alleviate again.
Above-mentioned axis hole 131 external side ends must be reserved the part spatial accommodation of block nut 14 and end cap 15 simultaneously, also can increase the volume and the weight of pedal body 13, and the setting of end cap 15 equally also can increase pedal 10 overall weight.
Because the ball bearing of main shaft 12 of above-mentioned external side end must lock nut 14 and screw member with 15 two of end caps and replace spacing, therefore, as long as wherein one screw member and do not screw really and replace or produce when loosening, 13 of this pedal spindle 11 and pedal bodies will produce endplay, such endplay causes producing axial rocking and mutual collision phenomenon each other easily when activity pivots relatively, and then quickens collision between the pivot structure each other and abrasion damage.
Above-mentioned block nut 14 can be subjected to the overlay masking of end cap 15, therefore under installing condition, operating personal can't be immediately and is checked affirmation apace and screw block nut 14 again, and after must earlier this end cap 15 being taken off, can carrying out, so quite inconvenience in the operation.
For making more light weight of pedal, existing many pedals can suitably reduce the length of pedal spindle under the axial width unmodified situation of pedal body; Yet, when the contraction in length of pedal spindle, the ball bearing of main shaft that its external side end is installed also will bear bigger load application force, can infer easily, above-mentioned pedal spindle external side end adopts the pivot structure design of single ball bearing, will more can't bear so big load effect.Shorten the load increase problem that pedal spindle is derived for solving, 20 pivot structures of another pedal as shown in Figure 2, be to change above-mentioned single ball bearing 12 into two ball bearing of main shafts 21 mutual structures side by side, just the opposing sidewalls with 212 of ring 211 and outer shrouds in the two bearings 21 abuts against each other, in the hope of improving the load bearing strength; Yet such way can only merely be improved the shortcoming of above-mentioned pedal 10 on the load bearing strength, and all the other problems also fail to obtain effective solution.
