Description
Technical field
The utility model is related to engine timing device, particularly for a kind of compact of engine chain tensioner
Tight device housing.
Background technology
At present in the machinery industries such as automobile making, internal combustion engine, the stretcher assembly of engine timing system is arranged on cylinder
Body or cylinder cap front end, basic function are to reduce timing chain vibration amplitude, vibrational energy absorbed, so as to reduce the noise of chain
And shake.Stretcher assembly is the very important parts of timing system, and the housing of stretcher assembly as stretcher each
The carrier of sub- part is particularly important.Conventional stretcher complex structure, sub- part is numerous, how to be set in limited arrangement space
Meter stretcher shell structure, it is the problem that design engineer needs customer service to integrate the parts such as plunger, check valve, check pawl.
The content of the invention
The purpose of this utility model is to provide a kind of compact stretcher housing, solves above-mentioned conventional stretcher housing
Complex structure, the sub- part of engine tensioner is more, difficult arrangement, and take up room big problem, and there is compact conformation, height to collect for it
Cheng Hua, intensity advantage high.
The technical scheme that the utility model is used is：The compact stretcher housing carries plunger working chamber, working chamber
Bottom is connected by fuel feed hole with the oil storage tank of plunger working chamber outside side, is characterized in that：It is close in the oil storage tank
Oil groove is drawn in being connected with proximally by narrow passage for plunger working chamber opening, and shell bores are provided with the outside of narrow passage, draws oil
Groove sidewall is provided with lubricating oil pump chain greasisng oilhole, draws and reinforcement is additionally provided between oil groove and oil storage tank, in plunger working chamber
Opening portion side wall is provided with locking pin-and-hole.
The oil storage tank and draw oil groove and be arranged on working chamber outside the same side, and oil storage tank and draw the outer face of oil groove same
One plane.
It is outside after the plunger working chamber relative with oil storage tank to be provided with plane boss.
The good effect that the utility model has is：The compact stretcher housing is by near plunger working chamber opening
Be connected with to draw oil groove and set proximally by narrow passage and be connected with and draw oil groove, make its compact conformation, Highgrade integration, intensity high energy
Enough make stretcher quick response, so as to ensure that engine can more be stablized on startup；And by drawing the lubricating oil pump chain of oil groove
Bar oilhole is lubricated for lubricating oil to lubricating oil pump chain, reduces single lubricating oil pump chain cooling nozzles, reduces into
This, reduces assembly process, improves efficiency of assembling.
Brief description of the drawings
The utility model is further described below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the utility model embodiment；
Fig. 2 is the utility model plunger working chamber open end structural representation；
Fig. 3 is the utility model embodiment rear structure schematic diagram.
Number explanation in figure：Oil groove, 4 narrow passages, 5 top spiral shells are drawn in 1 plunger working chamber, 2 lubricating oil pump chain greasisng oilholes, 3
Bolt mounting hole, 6 reinforcements, 7 oil storage tanks, 8 fuel feed holes, 9 lower bolt mounting holes, 10 locking pin-and-holes, 11 plane boss.
Specific embodiment
1 to 3 describe concrete structure of the present utility model in detail with reference to the accompanying drawings, embodiment is a kind of compact stretcher shell
Body, as illustrated in fig. 1 and 2, the compact stretcher housing carry plunger working chamber 1, the important feature of plunger working chamber tension device,
It is internal for assembling the structures such as stretcher plunger, check valve assembly, and the precision of its size directly determines the performance of stretcher；Post
Plug working chamber 1 bottom is connected by fuel feed hole 8 with the oil storage tank 7 of plunger working chamber outside side, and oil storage tank 7 has storage machine oil
Function, particularly when engine shut down be again started up during, the machine oil in oil storage tank 7 can enter quickly through fuel feed hole 8
Enter the high-voltage oil cavity of tension device, the rapid tensioning to timing chain can be realized, so as to ensure that engine stabilizer works；In oil storage
Groove 7 draws oil groove 3 near being connected with proximally by narrow passage 4 for the opening of plunger working chamber 1, and the outside of narrow passage 4 is provided with housing
Mounting hole, draws the side wall of oil groove 3 and is provided with lubricating oil pump chain greasisng oilhole 2, draws and reinforcement is additionally provided between oil groove 3 and oil storage tank 7
Muscle 6, drawing oil groove 2 has the function that machine oil is introduced oil storage tank 7 from engine main oil gallery, while can into the machine oil for drawing oil groove 2
Lubricating oil pump chain greasisng is given with by lubricating oil pump chain greasisng oilhole 2, the purpose for reducing chain wear is played；Reinforcement 6 has
The function of stretcher casing rigidity is improved, in the course of the work, very big by timing system load, exclusive requirement is strong for stretcher
Spending sufficiently high housing can well meet the use requirement of engine.It is provided with the opening portion side wall of plunger working chamber 1
Locking pin-and-hole 10, the locking pin-and-hole is used to assemble stretcher lock pin, stretcher it is unassembled on the engine before, locking
Pin makes stretcher plunger be locked inside stretcher locking pin-and-hole, prevents plunger and ejects suddenly, causes the risk hurted sb.'s feelings.The shell
Body mounting hole includes that upper bolt mounting hole 5 and lower bolt mounting hole 9 are used to install stretcher fixing bolt；
As a further improvement, oil storage tank and drawing oil groove and being arranged on working chamber outside the same side, and oil storage tank and draw oil groove
Outer face on the same plane, be easy to be connected installation with engine；As shown in figure 3, after the plunger working chamber relative with oil storage tank
Outside is provided with plane boss 11, the production batch number for making quarter stretcher, obtains stretcher date of manufacture and batch
Effectively tracking, prevents stretcher from cannot search batch when there are quality problems.
In sum, the purpose of this utility model is realized.
