Description
Technical Field
The utility model relates to a transfer case field, specific saying so relates to a novel disconnected axle transfer case.
Background
The transfer case is a device for distributing power of the engine, and can output power to the rear axle or to both the front and rear axles. From this perspective, it can be seen that the transfer case is actually a fitting on a four-wheel drive vehicle. With the development of the four-wheel drive technology, the transfer case is also changed all the time, and the transfer case with different styles is gradually formed, and the basic principles and the functions of the transfer case are different from those of the four-wheel drive vehicle matched with different requirements. However, no matter which type of transfer case is used, the input end and the output end of the input shaft of the transfer case are only sleeved with one bearing, the rotation precision of the whole input shaft is ensured only by the pair of bearings, and along with the increase of the working time and the use times, the bearings are worn inevitably, so that the service life of the transfer case is shortened slowly until the transfer case is invalid. If one of the input shaft bearings fails, the rotation precision of the whole input shaft is affected, and the working performance of the whole transfer case is affected.
The main function of the bearing is to support the mechanical rotating body, reduce the friction coefficient in the moving process and ensure the rotation precision; the life of a bearing is generally related to the working load and temperature to which it is subjected. In practical application, the working load carried by the bearing is often larger than the corresponding fatigue endurance limit load, and after working to a certain period, or later or earlier, the bearing can not be used continuously because the electrical fatigue limit of the material per se is reached, and the bearing is subjected to fatigue spalling. Even if the operational loads of certain bearings are below their respective endurance limit loads, wear failure can occur due to the problem of hard-to-root bearing contamination. The bearing can generally bear the working temperature of 120 ℃, and if the temperature exceeds the working temperature, the structure of a bearing material is changed, so that the load capacity and the service life of the bearing are reduced; in practice, the transfer case input shaft typically operates at a temperature above this temperature.
