Embodiment Construction
[0025] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings; it should be noted that the embodiments are illustrative, not restrictive, and cannot limit the protection scope of the present invention.
[0026] A teaching experiment device for simulating the force of a bicycle running on a road surface, which is composed of a bicycle 1, a treadmill 2 and a connecting device 3, the connecting device is installed on the treadmill and is used for connecting the treadmill and the bicycle. Each part is described in detail below:
[0027] 1. Bicycle:
[0028] The basic structure of a bicycle is divided into three parts:
[0029] ⑴. Guidance system consists of handlebar, front fork, front axle, front wheel, frame and saddle. Among them, the vehicle frame is the skeleton of the bicycle, and it bears the largest weight; the vehicle frame includes an upper tube, a lower tube, a seat tube, a rear fork upper tube, and a r...

The invention relates to a teaching experiment device for simulating a driving force of a bicycle on a road surface, and the device consists of the bicycle, a running machine, and a connection apparatus. The bicycle consists of a guide system, a drive system, and a braking control system. The running machine consists of a pedestal, a vertical column frame, and a control panel. The connection apparatus consists of a support part, a handlebar (seat) connection part, and an auxiliary wheel part. The support part consists of a clamping board, a vertical column, a cross support, a vertical shaft, and a locking pressure ring, wherein the clamping board, the vertical column, the cross support, the vertical shaft and the locking pressure ring are connected in an upward manner. The handlebar (seat) connection part consists of a handlebar (seat) locking ring, a handlebar (seat) connection telescoping shaft, a connection sleeve seat, and a linear bearing, wherein the handlebar (seat) locking ring, the handlebar (seat) connection telescoping shaft, the connection sleeve seat and the linear bearing are connected sequentially. The auxiliary wheel part consists of an extending shaft, a locking unit, a wheel support, and a wheel. The device can simulate the driving on the road surface, and is not limited by an additional external force. A vehicle body force-bearing part is usually in a complex combined deformation structure, and the device can enable multiple static and dynamic mechanic tests to be carried out on the vehicle (test bench) in a centralized manner.
Description
technical field [0001] The invention relates to the technical field of teaching devices for material mechanics experiments, in particular to a teaching experiment device for simulating the force of a bicycle running on a road surface. Background technique [0002] Material mechanics experiment is a basic mechanics experiment, and it is a technical basic course for most engineering majors in colleges and universities. The existing experimental content and teaching methods are far from enough to be combined with daily life and engineering practice. For example, at present, most of the test devices used to simulate bicycle driving on the road in China are testing equipment, which are used to detect bicycles under specific operating conditions. People can't go up to simulate road riding, and the price is expensive; generally there are bicycle dynamic road condition testing machines, bicycle dynamic walking durability testing machines and bicycle brake shifting comprehensive perf...
