Abstract

A front-drive rear-steering recumbent bicycle of the present invention, wherein a bicycle beam 1 is in connection with a bicycle integral body, a front part of the main beam 1 is in welded connection with a front fork and a splicing chain wheel bracket, a middle part is fixedly equipped with a chaise longue 4 on top, a steering handle shaft 10 is in loose joint with a steering handle 9 underside, a backside is in welded connection with a steering shaft sleeve 3. A steering shaft 2 is in connection with a rear steering fork 7 and is in loose joint with the steering shaft 3 and can rotate free, the rear steering fork 7 is in upper loose joint with a rear steering wheel 6, a rear steering fork right joint bearing 22 and a rear steering fork left joint bearing 23. An upside of the steering handle 9 is in connection with a steering handle right joint bearing 20 and a steering handle left joint bearing 21, the rear steering fork right joint bearing 22 and the steering handle left joint bearing 21 is are connected by a connecting rod A17, the rear steering fork left joint bearing 23 and the steering handle right joint bearing 20 are connected by a connecting rod B18. A front driving wheel 5 is in loose joint with a front fork 8, and is equipped with a flywheel 15 and a speed regulation guider 11 in the middle, pedals 16 and a chain wheel 14 are in loose joint with a chain wheel bracket 13, the chain wheel 14 and the flywheel 15 are connected by a chain 19.

Description

technical field [0001] The invention belongs to the field of sports bicycle manufacturing, in particular to a novel front-drive rear-steering recumbent bicycle. Background technique [0002] The recumbent bicycle is a special-shaped bicycle. It has front and rear wheels just like ordinary bicycles. Generally, the front wheel is the steering wheel and the rear wheel is the driving wheel. However, the recumbent bicycle has the characteristics of lying down and riding , it is destined that its drive chain must be installed at the front of the reclining car, and because the two-wheel track is too long, the transmission chain it uses is too long, because the chain is too long, it is necessary to use the chain guide wheel and the chain guide tube , which not only increases the cost, but also increases the resistance, so that the physical exertion caused by cycling is also too large. Contents of the invention [0003] In order to solve the technical problems of too long transmis...
