The invention discloses a folding bicycle without a chain. The folding bicycle comprises a bicycle body, a folding bicycle frame and a gear type transmission mechanism; a rear wheel is larger than a front wheel in diameter; a rotating shaft of foot bars on the bicycle frame is coaxial with the rear wheel and is in transmission connection with the rear wheel through the gear type transmission mechanism; the bicycle frame comprises a beam frame, the front end of the beam frame is connected with the front end of a lower rotating frame of a seat arranged on the beam frame in a front-back deflection and locating mode, a folding rotating shaft is coaxially connected with a connecting sleeve ring which is connected with a steering sleeve in a fastening mode, and a steering shaft bar is sleeved in the steering sleeve in a lifting mode; the rear end of the lower rotating frame of the seat is connected with the lower end of a middle rotating frame of the seat through a seat adjusting and locking device in a front-back deflection adjusting and locating mode, the upper end of the middle rotating frame of the seat is connected with the lower end of an upper rotating frame of the seat in a front-back deflection adjusting and locating mode, and the upper end of the upper rotating frame of the seat is connected with the seat; the middle portion of the lower rotating frame of the seat is connected with the middle portion of the beam frame through a damping spring. Safety, reliability and riding efficiency are all improved.
Description
technical field [0001] The invention belongs to the technical field of bicycles and relates to a chainless folding bicycle. Background technique [0002] Bicycles are people's daily necessities. Chain and gear transmission mechanisms are mainly used. The chain transmission has the advantages of simple manufacture, convenient installation and maintenance, etc., but the chain transmission has disadvantages such as easy staining of clothes, detachment of the chain, and low transmission efficiency. Not easy to fold. [0003] With the improvement of people's living standards, the enhancement of low-carbon environmental protection and green health awareness, bicycles are favored by people again. However, as urban traffic becomes more and more congested, parking space is obviously insufficient, and bicycles are more likely to be stolen, these problems have affected people's enthusiasm for cycling. So people invented folding bicycles, so that they can be carried easily during th...
