Description

Technical Field

[0001] The utility model relates to the technical field of differentials, in particular to a high-position input and output power structure of a differential. Background Art

[0002] When model cars are driving on complex tracks or different terrains, such as curves, slopes, and sand, more precise power distribution is required to ensure driving stability and control. This has given rise to the demand for differentials, as differentials allow model cars to better adapt to wheel speed differences when turning, preventing wheel slippage and achieving more precise control.

[0003] Currently, all model remote control cars in the industry have differentials that input / output power in a conventional position, that is, the input / output power is placed in the middle of the differential. This position of the drive shaft hinders the placement of the motor, and the motor can only be located on the left or right side of the chassis. This position of the motor always has the center of gravity biased to one side, and the model toy car will shift to the heavier side in actual operation, making the remote control car more difficult to control. Utility Model Content

[0004] The purpose of the utility model is to provide a differential high-position input and output power structure, which has the advantages of balancing the center of gravity of the differential and facilitating adjustment of the differential gear ratio, thereby solving the problem that the current differential drive shaft is centered, resulting in a biased motor installation and a low center of gravity for a model toy car.
