11 异步娱乐车

工业中心童玉清副教授（E-mail：tyq@szpt.edu.cn）主持研发的异步娱乐车是一款新型娱乐健身人力车，适合在公园、广场等广阔场所供人们骑行，可单人骑行，也可双人骑行。这款车主要由车架、两轮径较大的驱动前轮、小轮径万向后轮组成。人坐在座椅上骑行异步娱乐车时，需手脚并用该车才能前行。双手摇动摇杆，双脚踩脚踏板并分别通过一级链传动装置带动两前轮转动，由于手脚很难达到完全同步，再加上左右轮两边的链传动装置传动比不同，使得左右两前轮极易产生转速差，初驾者难以控制车的骑行方向，车会左右蛇形前进。但是骑行一段时间后，手脚动作逐渐协调，骑行者就能够比较自如地控制车体直行或者左转、右转甚至后退行驶，骑行的速度也会逐渐加快。在两前轮的前方快速加装一座椅和万向轮，此车也可供两人面对面同时骑行。一个人手摇，另一个人脚踩，通过两人的默契配合来控制车体直行、左转、右转和后退行驶。单人骑行异步娱乐车可以锻炼身体协调性，双人骑行时可以考验两个人配合的默契程度，配套举办一些趣味比赛项目，可以使骑行更充满乐趣和挑战，有广泛的应用前景。

Yibu Fun Bicycle

Yibu fun bicycle is designed for riding in spacious place like parks, squares, etc. Bikes for single riding or double riding are available, which consists of bike frame, two large wheel diameter driving front wheel and small wheel diameter universal rear wheel. Riders use hands and feet simultaneously to make the bike move forward. Hands are used to shake rocker, and feet step on the pedal and drive rotation of the two front wheels through the first level of chain. For the beginners, it is hard to make the hands and feet completely to be in sync,so the ratio of chain transmission gear of wheels on both sides tends to be different, and two front wheels are prone to have speed difference. It is hard for initial drivers to control direction, so the bike always serpentines forward. But once you ride for a while, hands and feet become gradually coordinated, the rider can freely control the bike to go straight or turn left, even go back .The speed will also gradually be fast. If a seat and universal wheel in front of the two front wheels are added, two riders can ride face to face at the same time,with one cranking, and the other trending, controlling the direction. Single riding of Yibu fun bicycle can improve body coordination; Double riding can enhance the coordination. Riding will be more interesting and challenging if recreational competitions are involved.
