Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
A kind of depression bar bicycle as shown in Figure 1 and Figure 2, including bicycle rear 1, the centre of trailing wheel 1, which runs through, to be provided with Axle sleeve 2, the side of axle sleeve 2 are fixed with one-way transmission gear 3, and the side of travelling gear 3 is provided with the company engaged with travelling gear 3 Gear 4 is connect, the connection gear 4 includes little gear 401 and the gear wheel 403 being connected by axle 402 with little gear 401, described Connection gear 4 is provided with the travelling gear 5 engaged with little gear 401, and the one-way transmission gear 3 is connected with the first rear axle 6, described The one end of first rear axle 6 and the centre of one-way transmission gear 3 are affixed, and the other end is connected with left one-way wheel 7, and first rear axle 6 passes through Travelling gear 5 is worn, the left front end of one-way wheel 7 is provided with left depression bar 8;
The opposite side of axle sleeve 2 is provided with the second rear axle 9 being connected with axle sleeve 2, and the outside of the second rear axle 9 is connected with right list To wheel 10, the right one-way wheel front end is provided with right depression bar 11.
Preferably, the left depression bar 8, right depression bar 11 are connected by bicycle chain 12 with fulcrum 13, the left depression bar, the right side The anglec of rotation of depression bar is 0-180 °, releases existing 360 ° of rotations of bicycle pedal.
Preferably, first rear axle, the second rear axle run through axle sleeve, and first rear axle, the second rear axle interconnect.
Preferably, first rear axle 6, the second rear axle 9, the both ends of axle 402 are equipped with bearing 14, and the bearing 14 is located at certainly In overhead crane support 15, bike rack 15 plays a part of protecting whole interior structure.
Preferably, first rear axle 6, the second rear axle 9 run through bike rack 15.
Embodiment 1:
During use, when user steps on left depression bar 8, left one-way wheel 7 is driven to move downward, left one-way wheel 7 is fixed on On first rear axle 6, the first rear axle 6 is driven to rotate, the rotation of the rotating band nutating gear 5 of the first rear axle 6, travelling gear 5 leads to Cross the rotation of the little gear 401, the transmission drive trailing wheel 1 of gear wheel 403 of the connection gear 4 engaged with travelling gear 5, connection gear It is driven between little gear 401 and gear wheel 402 in 4 by axle 402;When user steps on right depression bar 11, drive right One-way wheel 10 is rotated, and right one-way wheel 10 is fixed on the second rear axle 9, and right one-way wheel 10 drives drives transmission by the second rear axle 9 The rotary motion of gear 5, trailing wheel 1 is driven by the little gear 401 of connection gear 4, gear wheel 403 when travelling gear 5 rotates Rotation.
