Abstract
The utility model discloses a kind of oil duct shock-reducing and noise-reducing structure of built-in filter, including oil duct, filter and screw plug, filter is placed in oil duct and the front end of filter is spacing by the step surface in oil duct, screw plug is installed in the termination of oil duct, guide rod and cylindrically coiled spring are installed between filter and screw plug, guide rod is divided into guide rod portion and end head, the tail end of filter is provided with pilot hole and stretches into for guide rod portion, end head is mated with the internal diameter of oil duct, and the rear end face of end head is against the front end face of screw plug, the front end of cylindrically coiled spring is against the rear end face of filter, the rear end of cylindrically coiled spring is against the front end face of end head.Using the guiding of the elastic compression and guide rod of cylindrically coiled spring, effectively prevent filter radial-play and axial movement, vibrating noise is produced because of loosening after solving the problems, such as filter long-play, oil duct cleaning of being more convenient for is required to reduce to the accurate to dimension of parts.
Description
Technical field
This utility model is related to technical field of automobile engine, and in particular to a kind of oil duct damping noise reduction of built-in filter
Structure.
Background technology
Filter is installed in engine oil channel, filter is installed screw plug or steel ball press-loading is installed again.Screw plug
Or the filter in oil duct is pushed against by steel ball.The subject matter of presence is：(1) steel ball press-loading, is not easy to oil duct cleaning, clearly
Clean when safeguarding oil duct, existing structure can be damaged；(2) screw plug or steel ball press-loading are installed, after long-play, filter
Device loosens in the oil duct and produces vibrating noise, is found by analysis, the reason for produce vibrating noise be filter axial movement and
Radial-play causes；(3) for ensureing installation reliability, element precision is had high demands, to ensure screw plug or steel ball just
Filter is pushed against.
Utility model content
After this utility model aims to solve the problem that filter long-play, the problem for producing vibrating noise is loosened in oil duct.
For this purpose, the technical scheme that adopted of this utility model for：A kind of oil duct shock-reducing and noise-reducing structure of built-in filter, bag
Oil duct, filter and screw plug is included, the filter is placed in oil duct and the front end of filter passes through the step surface in oil duct
Spacing, screw plug is provided with guide rod and cylindrical screw bullet installed in the termination of oil duct between the filter and screw plug
Spring, the guide rod are divided into guide rod portion and end head, and the tail end of the filter is provided with pilot hole and stretches into for guide rod portion, the end
Head is mated with the internal diameter of oil duct, and the rear end face of end head is against the front end face of screw plug, the cylindrically coiled spring
Front end is against the rear end face of filter, and the rear end of cylindrically coiled spring is against the front end face of end head.
Used as the preferred of such scheme, the pilot hole of the filter tail end carries pattern draft, and the guide rod portion carries
Taper is simultaneously mated with pilot hole, the processing and manufacturing of convenient filter.
The beneficial effects of the utility model：By setting up guide rod and cylindrically coiled spring, the end head of guide rod and oil duct
Internal diameter mates, and the front end of guide rod is stretched in the pilot hole of filter tail end, effectively prevent filter radial-play；Meanwhile, circle
The front end of post helical spring is against the rear end face of filter, it is therefore prevented that filter axial is moved；Bullet using cylindrically coiled spring
Property compress and guide rod guiding, produce vibrating noise after efficiently solving the problems, such as filter long-play because of loosening；Adopt
Oil is carried out with screw plug stifled, compare the structure of steel ball press-loading, oil duct cleaning of being more convenient for；Processing dimension essence to parts
Degree requires to reduce, and so as to reduce cost, improves the fault-tolerance of related components size.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Partial enlarged drawings of the Fig. 2 for Fig. 1.
Specific embodiment
Below by embodiment and accompanying drawing is combined, the utility model is described in further detail：
In conjunction with shown in Fig. 1 Fig. 2, a kind of oil duct shock-reducing and noise-reducing structure of built-in filter, mainly by oil duct 1, filter
2nd, screw plug 3, guide rod 4 and cylindrically coiled spring 5 are constituted.
Filter 2 is placed in oil duct 1, and the front end of filter 2 is spacing by the step surface in oil duct 1.Screw plug 3 is installed
The female thread mated with screw plug 3 is provided with the termination of oil duct 1, the tip position of oil duct 1.
Guide rod 4 and cylindrically coiled spring 5 are installed between filter 2 and screw plug 3.4 points of guide rod be guide rod portion 4a and
End head 4b, the diameter of guide rod portion 4a are less than the diameter of end head 4b.The tail end of filter 2 is provided with pilot hole for guide rod portion 4a
Stretch into, end head 4b is mated with the internal diameter of oil duct 1, prevent having radial clearance between guide rod 4 and oil duct 1 and radial direction is rocked.Termination
The rear end face of portion 4b is against the front end face of screw plug 3, and the front end of cylindrically coiled spring 5 is against the rear end face of filter 2, cylinder
The rear end of helical spring 5 is against the front end face of end head 4b.
Preferably, the pilot hole of 2 tail end of filter carries pattern draft, and guide rod portion 4a is with tapered and mate with pilot hole.
Certainly, filter 2 can also be using processing, and pilot hole is set to cylindrical hole, and now guide rod portion 4a is also cylinder.
