Owing to adopting said structure, the master of the integral type main cone bearing unit structure of the utility model subtracts assembly compared with existing passenger vehicle main gearbox assembly, has following beneficial effect:
1. can simplify assembly technology:
Due to active conical tooth wheel support bearing employing of the present utility model is integral type main cone bearing unit, it is not need running in bearings outer ring, two bearing inner races directly press-fit to bearing support, without adjusting bearing play and play, simplify assembly technology, but also the manufacturing procedure of minimizing part, thereby save manufacturing procedure and cost of production, improve output and quality.
2. can improve integral rigidity:
Due to active conical tooth wheel support bearing employing of the present utility model is integral type main cone bearing unit, under equal design space, can increase the internal-and external diameter of bearing, the intensity and the rigidity that make winner subtract assembly strengthen, thereby can improve integral rigidity, make it in the time of coupling retarder, reduce vibrating noise, avoid the hidden danger of abnormal sound, thereby further reduce vibration and the noise of car load, improve the comfort level of car load.
3. being conducive to car load chassis structure arranges:
Due to active conical tooth wheel support bearing employing of the present utility model is integral type main cone bearing unit, its structure is compacter, can shorten the main height that subtracts assembly, saves chassis arrangement space, transmission shaft can better be arranged, be conducive to the layout of car load chassis structure.
Below, the technical characteristics that the master of the integral type main cone bearing unit structure to the utility model subtracts assembly is in conjunction with the accompanying drawings and embodiments further described.
