Abstract
The utility model discloses a bicycle wheel disc, which is elliptical. A bicycle pedal arm forms an included angle of 15 DEG and 45 DEG with the horizontal direction of the elliptical wheel disc. The length ratio of a major axis and a minor axis of the elliptical wheel disc is greater than 1 but less than 2. A disk axis of the elliptical wheel disc is positioned in the center of the elliptical wheel disc. The utility model has the advantages that the bicycle uses the elliptical wheel disc, which is in accordance with the ergonomics principle, and the utility model can reasonably make use of force application when the person rides the bicycle. The utility model is suitable for manpower vehicles such as racing vehicle, bicycle, etc.
Description
Technical field:
The utility model relates to a kind of bicycle wheel disc, belongs to the bicycle accessories field.
Background technology:
Existing bicycle wheel disc is circular, and the people can not well be brought into play power when the application of force.Be not suitable in circular movement having only when left and right sides pin takes turns to depress all the time along tangential direction such as people's application of force direction, the application of force is substantially in tangential direction, and in other position, people's the application of force can not all effectively be utilized.Like this when driving, have only 1/2nd power to be used effectively.
The utility model content:
The purpose of this utility model is to provide a kind of human engineering that meets, and a kind of bicycle wheel disc of the application of force when more rationally utilizing people's treadmill.
The purpose of this utility model is to be implemented by following technical scheme:
Described wheel disc is oval, and the angle of the minor axis of bicycle pedal arm and described oval wheel disc is 15 °-45 °.
The major axis of described oval wheel disc and the length of minor axis than for greater than 1 and less than 2 between.
The dish axle of described oval wheel disc is positioned at the center of described oval wheel disc.
The utility model has the advantages that: bicycle adopts oval wheel disc, meets the human engineering principle, the application of force in the time of can rationally utilizing people's treadmill, and it is applicable to rickshaws such as racing car, bicycle.
The drawing explanation of accompanying drawing:
Fig. 1 is a theory structure scheme drawing of the present utility model.
Fig. 2 is a structural representation of the present utility model.
Embodiment:
Embodiment 1: as shown in Figure 1 and Figure 2, bicycle wheel disc 1 is oval, and bicycle pedal arm 2 is 15 °-45 ° with the included angle A of the minor axis of oval wheel disc 1, can be 30 °.The major axis a of oval wheel disc and the length of minor axis b than greater than 1 and less than 2 between, preferably 9: 7.The dish axle 3 of oval wheel disc 1 is positioned at the center of oval wheel disc.On cycle chain, swelling device 4 is set, the degree of tightness that is used to solve because of adopting the chain that oval wheel disc 1 causes changes; Also has simultaneously the function of storage, exoergic.
