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.
