The invention relates to a front-wheel-driving and rear-wheel-steering type bicycle of which the bicycle frame can be folded and the weight can be reduced. The top of a steering rod is connected with a handle bar, the middle of the steering rod is connected with the coupler; the lower end of the steering rod is connected with the rear wheel; the front end of the saddle is in slide connection withthe steering rod, the rear end of the saddle is connected with the top of a supporting rod; the middle part of the supporting rod is connected with the coupler; and the bottom of the supporting rod is connected with a front wheel. A left gear and a right gear connected with a left supporting rod and a right supporting rod are respectively and internally meshed with a left driven gear and a right driven gear on the principal shaft of the front wheel. When the bicycle is ridden, driven by the handle bar, the front wheel is driven to rotate by the driven gear and the principal axis; when the bicycle steers, the steering rod and a positioning ring rotate around the axis of a connector shaft sleeve and the rear wheel is driven to rotate by a rear wheel fork so as to realize steering. When the bicycle is folded, the saddle can be turned backwards to enable the left supporting rod, the right supporting rod and the steering rod to tuck up around the left revolving shaft and the right revolving shaft of the connector.
Description
technical field [0001] The invention relates to a bicycle, in particular to a front-drive and rear-rudder bicycle that can realize folding of the frame and reduce the weight of the bicycle through front-wheel drive and rear-wheel steering. Background technique [0002] At present, the known bicycles are heavy because of the traditional driving method and the vehicle frame structure, and the vehicle frame is inconvenient to be folded. Contents of the invention [0003] In order to overcome the shortcomings of the existing bicycles that are heavy and the frame is not easy to fold, the present invention provides a front-drive and rear-rudder bicycle, which can realize folding and lowering of the bicycle frame by means of front-wheel drive and rear-wheel steering. vehicle weight. [0004] The technical scheme that the present invention solves its technical problem is: the present invention comprises handlebar, steering rod, vehicle seat, coupler, rear wheel fork, rear wheel, ...
