Description

Technical Field

[0001] The utility model relates to the technical field of entertainment equipment, and more specifically to a mechanical transmission reversing device for bumper cars. Background Art

[0002] Bumper cars in amusement parks are entertainment tools deeply loved by people. The existing transmission reversing device of the bumper car main body is driven by two pairs of bevel gear pairs. One pair of bevel gear pairs is connected to the wheels at the middle position of the front end of the vehicle body, and the other pair of bevel gear pairs is connected to the steering wheel through a universal joint. During the driving process of the bumper car, the bevel gear pair transmission will generate relatively large noise, and the friction between the bevel gear pairs during transmission is relatively large, making the vehicle steering not flexible enough and the user experience relatively poor.

[0003] Both belt drive and chain drive use an intermediate flexible member (belt or chain) to transmit the motion and power of the driving shaft to the driven shaft. Belt drive is divided into friction drive and meshing drive, and chain drive belongs to meshing drive. Compared with gear drive, both belt drive and chain drive have the characteristics of smooth transmission, low noise, and high transmission efficiency, and are also applicable to occasions where the axial distance between two shafts is relatively large.
