Abstract
The invention discloses a timing chain wheel cover. A fixing device used to fix an engine oil gauge tube is arranged on the bottom left or bottom right of the external surface of the timing chain wheel cover. A path goes through the fixing device. One end of the path communicates with the engine oil gauge tube, while the other end communicates with a cavity of an oil pan. The advantage of the invention is that as a pedestal on the timing chain wheel cover or the pedestal and a fixing seat stretching out from the pedestal are used to fix the engine oil gauge tube, the space of the timing chain wheel cover itself and clearances of parts around are fully used; the problem that the engine oil gauge tube is difficult to be arranged will not happen even for a structurally concise engine.
Description
Technical field
The present invention relates to a kind of timing sprocket shroud, especially a kind of timing sprocket shroud that is used for fixing engine oil scaleplate pipe.
Background technique
For guaranteeing that component to engine interior are lubricated and cool off, a certain amount of lubricant oil of must in engine sump tank, annotate, the maintenance dose of lubricant oil is measured by the engine oil scaleplate pipe in the insertion oil sump and is checked.Generally speaking, the engine oil scaleplate pipe of motor is fixed on framework or the oil sump by the dipstick pipe holder, and engine oil scaleplate pipe needs suitably crooked different radian to adapt to the layout of complete machine.And to the motor of compact structure, because will there be the problem that is difficult to arrange engine oil scaleplate pipe in its framework, oil sump and the space of component is limited on every side.
Summary of the invention
The object of the present invention is to provide a kind of structure of utilizing timing sprocket shroud self to fix the timing sprocket shroud of engine oil scaleplate pipe.
The objective of the invention is to be achieved through the following technical solutions: a kind of timing sprocket shroud, it is characterized in that: the left bottom of the outer surface of timing sprocket shroud or place, lower right are provided with the fixing device that is used for fixing engine oil scaleplate pipe, an end that is penetrated with path and path in the fixing device is communicated with engine oil scaleplate pipe, and the other end is communicated with the cavity of oil sump.
The invention has the advantages that: the base that covers with timing chain wheel or as fixing device fix engine oil scaleplate pipe with base and the fixed base that stretches out on base has made full use of the space of timing sprocket shroud self and the gap of component on every side; For the motor of compact structure, there is not the problem that is difficult to arrange engine oil scaleplate pipe yet.
Description of drawings
Fig. 1 is the worm's eye view of the timing sprocket shroud of band fixed base;
Fig. 2 is the plan view of the timing sprocket shroud of band fixed base;
Fig. 3 is the plan view of the timing sprocket shroud of band fixed base;
Fig. 4 is the erection drawing of timing sprocket shroud, engine oil scaleplate pipe, flange and the oil sump of band fixed base.
Embodiment
When the timing train of motor adopt be the timing chain transmission system time, timing sprocket shroud has the dust-tight function on the one hand, will prevent the oil leakage of lubricated chain drive system on the other hand, timing sprocket shroud generally adopts metal ceramic but not plastic parts for this reason.In this case,, and himself enough spaces are arranged also if timing sprocket shroud is enough with the spatial joint clearance of component on every side, so fully might be thereon fixing engine oil scaleplate pipe.
Positive apparent direction of the present invention is meant the external casing of facing timing sprocket shroud, left bottom or place, lower right at the outer surface of timing sprocket shroud 10 are provided with the fixing device 30 that is used for fixing engine oil scaleplate pipe 20, according to the space of reality, fixing device 30 is designed to simple and preferred dual mode: the fixing device 30 of plain mode is for being the base 31 of mesa shaped; The fixed base that is the boss shape 32 that the fixing device 30 of optimal way comprises base 31 and is provided with on base 31.Be penetrated with path 40 in the fixing device 30, as Fig. 1, shown in Figure 3, and an end of path 40 is communicated with engine oil scaleplate pipe 20, and the other end is communicated with the cavity of oil sump 70.
Because the difference of the fixing device 30 on the timing sprocket shroud 10 can be divided into timing sprocket shroud .10 that is not with fixed base 32 and the timing sprocket shroud 10 of being with fixed base 32 to timing sprocket shroud 10, as shown in Figure 2.
Engine oil scaleplate pipe 20 is fixed on the fixing device 30, its means of fixation is divided into two kinds: one, engine oil scaleplate pipe 20 is connected with flange 50, wherein, flange 50 can replace with other support, offer tapped hole 51 on flange 50 and the fixing device 30, flange 50 is connected with fixing device 30 by bolt 60, and the joint is provided with sealing gasket to prevent oil leakage; Its two, engine oil scaleplate pipe 20 is provided with pipe thread with the position that fixing device 30 is connected, promptly the two only needs to be connected by pipe thread, does not need flange 50 is set in addition, and is provided with seal ring between the two to prevent oil leakage.The lower end surface of timing sprocket shroud 10 is connected with oil sump 70 by bolt, and the joint is provided with sealing gasket to prevent oil leakage.
As seen, because the difference of fixing device 30 and the difference that engine oil scaleplate pipe 20 is fixed on the means of fixation on the fixing device 30, engine oil scaleplate pipe 20 has four kinds of compound modes with the combination of fixing device 30.In the present invention, preferred a kind of being further described wherein.
Figure 4 shows that the erection drawing of timing sprocket shroud 10, engine oil scaleplate pipe 20, flange 50 and the oil sump 70 of band fixed base, stretch out the fixed base 32 of a boss shape on the base 31 at the place, left bottom of the outer surface of timing sprocket shroud 10, base 31 and fixed base 32 are the fixing device 30 among the present invention.Be penetrated with path 40 in base 31 and fixed base 32, an end of path 40 is communicated with engine oil scaleplate pipe 20, and the other end is communicated with the cavity of oil sump 70.Engine oil scaleplate pipe 20 is connected with flange 50, offers tapped hole 51 on flange 50 and the fixed base 32, and flange 50 is connected with fixed base 32 by bolt 60, and the joint is provided with sealing gasket to prevent oil leakage.
As mentioned above, core scheme of the present invention is to utilize the self structure of timing sprocket shroud, arranges that reasonably one is connected and fixed the position, is used for fixing engine oil scaleplate pipe.
