Abstract
The utility model relates to the field of automotive technology, a draining protection architecture is disclosed, including the camshaft, cam shaft connection braking bottom plate and both sides are sealed with the oil blanket, be equipped with the bush in the braking bottom plate, be equipped with the oil duct in the camshaft, the pump nozzle is connected to oil duct one end, oil duct in the other end UNICOM bush, the draining hole on through -hole and the UNICOM's bush is seted up to the oil duct in the bush, the draining hole is equipped with the draining mouth.
Description
Technical field
This utility model relates to automobile technical field, is specifically related to a kind of draining protection structure.
Background technology
When camshaft and back-plate contact area grease up, owing to being the regular frictions of two parts, so wanting enough grease ups.But owing to conventional seals uses "O"-ring to seal, unnecessary grease the most reasonably can not be discharged again, cause the too high inevitably spilling at camshaft " S " type end side of grease oil pressure, it is possible to fall on brake drum inwall and braking lining cloth, make braking ability be greatly lowered, cause great potential safety hazard.
Summary of the invention
The deficiency existed for prior art; technical problem to be solved in the utility model is; a kind of improvement to structure is provided; "O"-ring is sealed and is designed to oil sealing sealing; increase leak-off nozzle simultaneously, both can ensure that camshaft lubrication was sufficient, and unnecessary grease can have been discharged by leak-off nozzle again; avoid oil pressure too high from camshaft " S " end spilling drop onto brake drum inwall, affect braking ability draining protect structure.
For solving above-mentioned technical problem; technical solution adopted in the utility model is: a kind of draining protection structure; including camshaft; described camshaft connects back-plate and both sides oil sealing sealing, is provided with lining, is provided with oil duct in described camshaft in described back-plate; described oil duct one end connects pump nozzle; other end UNICOM lining internal oil channel, described lining internal oil channel offers the oil leak hole on through hole and UNICOM's lining, and described oil leak hole is provided with leak-off nozzle.
The advantage of this utility model draining protection structure is:
1, this utility model draining protection structure, both can at pump nozzle enough grease ups, improve lubrication, can avoid again grease enter brake drum, improve braking ability.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail.
As shown in Figure 1; a kind of draining protection structure; it is characterized in that: include camshaft 1; described camshaft 1 connects back-plate 3 and both sides oil sealing 2 seals, and is provided with lining 8, is provided with oil duct 9 in described camshaft 1 in described back-plate 3; described oil duct 9 one end connects pump nozzle 10; other end UNICOM lining internal oil channel 6, described lining internal oil channel 6 offers the oil leak hole 11 on through hole 5 and UNICOM's lining 8, and described oil leak hole 11 is provided with leak-off nozzle 7.
User is when maintenance, and grease up from pump nozzle 10, grease enters and be full of cam shaft bush internal oil channel 6 and oil-stored hole 4 by camshaft oil gallery 9, and excess oil can overflow from leak-off nozzle 7.Avoid overflowing into brake drum from S end.
It is an object of the invention to by the improvement to structure, "O"-ring is sealed and is designed to oil sealing sealing, increase leak-off nozzle simultaneously, both can ensure that camshaft lubrication was sufficient, unnecessary grease can be discharged by leak-off nozzle again, avoid oil pressure too high from camshaft " S " end spilling drop onto brake drum inwall, affect braking ability.The benefit of this mode is: both can at pump nozzle enough grease ups, improve lubrication, can avoid again grease enter brake drum, improve braking ability.
Certainly, described above is not to restriction of the present utility model, and this utility model is also not limited to the example above; those skilled in the art; in essential scope of the present utility model, the change made, change, add or replace, all should belong to protection domain of the present utility model.
