The invention relates to a three-bearing highway bicycle clamping pedal with an opposite-penetrating straight hole structure. The clamping pedal comprises a clamping pedal body, a rear buckle is hinged to the rear part of the clamping pedal body, and an elastic piece is arranged at the hinge part. A pair of opposite-penetrating straight holes used for allowing foot straps to penetrate through is formed in the rear middle portion of the clamping pedal body. A mandrel is arranged in the middle of the clamping pedal body in a penetrating mode. A needle bearing is arranged between the large-diameter section of the mandrel and the clamping pedal body. A pair of ball bearings is arranged between the small-diameter section of the mandrel and the clamping pedal body, and a bearing supporting sleeve is arranged between the two ball bearings. The tail end of the mandrel is fixed through a self-locking nut. The three-bearing highway bicycle clamping pedal has the advantages that the structure issimple and reasonable, the foot straps are directly used in cooperation with the opposite-penetrating straight holes, use is convenient, and weight increase caused by additional arrangement of a fixing device is avoided; and in addition, according to the highway bicycle clamping pedal, a three-bearing structure composed of the needle bearing and the pair of ball bearings is adopted between the mandrel and the clamping pedal body, and rotation is flexible and smooth.

    本发明涉及具有对穿直孔结构的三轴承公路自行车卡踏,包括有卡踏本体,卡踏本体的后部铰接有后卡扣,并在铰接部设置有弹性件,卡踏本体的中后部设置有一对用于穿置脚部束带的对穿直孔,卡踏本体的中部穿置有一芯轴,芯轴的大径段与卡踏本体之间设置有滚针轴承,芯轴的小径段与卡踏本体之间设置有一对滚珠轴承,两个滚珠轴承之间设置有轴承撑套,芯轴的尾端用自锁螺母固定。其优点在于:结构简单、合理,脚部束带直接配合对穿直孔使用,使用方便,也避免了因额外增加固定装置而导致的重量增加;另外,本公路自行车卡踏,芯轴与卡踏本体之间采用滚针轴承和一对滚珠轴承构成的三轴承结构,转动灵活、顺畅。
