AI Technical Summary
Existing heavy-duty commercial vehicle drive bevel gears can only be used with guide bearings of a single specification and size, resulting in poor versatility. Furthermore, when replacing the guide bearing, a matching drive bevel gear must be replaced, leading to inconvenience in use.
A drive axle active bevel gear structure was designed. The active bevel gear has a groove and is connected to a detachable mating radial shaft. The guide bearing is inserted into the mating radial shaft through a positioning hole to achieve a detachable connection. This avoids the risk of high speed ratio gears cutting the guide diameter of the active bevel gear and enhances its versatility.
It achieves adaptability to different guide bearing models and positions, reduces the weight of the drive bevel gear and guide bearing, enhances versatility, avoids damage to the guide diameter of the drive bevel gear, and simplifies the replacement process.
