Wash, realize non-maintaining, can both reduce operating bearing temperature, can take away foreign matter caused by friction again reduces the mill of bearing
Damage amount, so as to extend the service life of bearing；
2nd, in vehicle travel process, spindle nose cover core remains stationary state, helical oil groove rotates with hub assembly, spiral oil
Relative motion between the screw thread and Spindle nose cover outer core of groove inwall produces extruding to conduction oil makes its flowing, and due to heat conduction
Oil is more sticky, and speed is slower, and the cutting force of screw thread is bigger, and pump oil speed is faster, brake disc is cooled down rapidly；Need not be extra
The energy, no operating cost are provided；
3rd, the gap of cover core axle and groove, which coordinates, has certain buffering capacity, it is ensured that even if hub assembly is with vehicle
Generation of jolting, which loosens, does not interfere with pump oil effect yet；
4th, relief valve is used for the pressure release in pump oil hypertonia, prevents from destroying the oil sealing of hub assembly；
5th, the oil pipe mouth of pipe and oil leak hole of bearing both sides are arranged at, makes conduction oil sufficient lubrication, bearing cleaning, is not present
Dead angle, further extend the service life of bearing；
6th, oil leak hole extends to axle housing afterbody by oil supply pipe, is accommodated by the use of axle housing inner chamber as shoe cream room from bearing
The heat brought, further improves cooling effect；
7th, tubular roller intensity is high, and it is more smoothly that conduction oil can be made to circulate, and cooling effect is more preferable, further carries
High service life；
8th, filter core is used to filter out caused foreign matter in running, it is ensured that the cleaning of conduction oil, effectively extends making for bearing
Use the life-span；
9th, temperature sensor and liquid level sensor detect the state of conduction oil in real time, it can be determined that the state of bearing, in time
It was found that the different shape of bearing；
Tenth, need first to remove plug when opening Spindle nose cover, with the rotation of hub assembly, conduction oil is gradually discharged.
