The invention discloses a spline connecting structure for a rear hub and a rear flywheel of a field bicycle, the field bicycle comprises the rear hub, a shaft rod and the rear flywheel, the shaft rod is sleeved with the rear hub and the rear flywheel, two ends of the shaft rod are fixed on a frame of the field bicycle through a left nut and a right nut, and the rear hub is connected with the rear flywheel through a spline. Through the spline connecting structure of the rear hub and the rear flywheel, problems that the rear hub and the rear flywheel in a bicycle in field bicycle training are slipped and are frequently replaced are effectively solved. The spline connecting structure of the rear hub and the rear flywheel can reduce the diameter of the rear flywheel and reduce the number of teeth of the rear flywheel, so that the speed ratio of the field bicycle is increased, the riding speed of the field bicycle is increased, and the weight of the field bicycle is reduced.
本发明公开一种场地自行车后花鼓与后飞轮花键连接结构,所述场地自行车包括后花鼓、轴杆和后飞轮,所述后花鼓和后飞轮套设于轴杆上,所述轴杆两端通过左螺母和右螺母固定于场地自行车车架上,后花鼓与后飞轮通过花键连接。本发明通过后花鼓和后飞轮花键连接结构,有效解决场地自行车训练中自行车中的后花鼓和后飞轮之间产生滑丝,经常更换的问题。后花鼓和后飞轮花键连接结构,能够使后飞轮直径缩小,后飞轮的齿数减少,从而提高了场地自行车的速比,提高了场地自行车骑行速度,降低了场地自行车的重量。
