Embodiment
Below in conjunction with accompanying drawing, an embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subjected to the restriction of embodiment.
Flywheel shell of engine of the present utility model as shown in Figure 2, the left side of its sidewall 6 is flywheel casing and body applying end face, be called front-end face 1 (Fig. 1 is the front-end face schematic representation), the right of sidewall 6 is flywheel casing and gearbox engaged end face, is called ear end face 2 (Fig. 3 is the ear end face schematic representation).As shown in Figure 1, the flywheel casing front-end face is furnished with the pinion barrel 3 that holds the air compressor actuation gear, and pinion barrel 3 is cast as one with flywheel casing, and side, pinion barrel 4 is to be connected end face with the air compressor support, thereby realizes air compressor rear end layout.
As shown in Figure 2, flywheel casing all is furnished with trunk stiffening rib 14 and radial stiffening rib 11 on the two sides of sidewall 6, as shown in Figure 5, connects each flywheel casing bolt successively and crosses the banded trunk stiffening rib 14 of nail hole 8 formation, and this stiffening rib plays sealing strip simultaneously; The lug that connects screw 7 by each gearbox directes reach sidewall 6 and is shaft orientation reinforcing rib 10, and shaft orientation reinforcing rib one circle is axial arranged, and the quantity of muscle is decided on the quantity that gearbox connects screw 7; Connect the flywheel casing bolt and cross the radial stiffening rib 11 of shaft orientation reinforcing rib 10 formations of nail hole 8 and periphery, its muscle height is a little less than trunk stiffening rib 14; Connect bent axle Rear oil seal seat installation screw 9 and cross the radial stiffening rib 12 of nail hole 8 formation with the flywheel casing bolt of periphery, its muscle height is in radial stiffening rib 11; Connect adjacent radiation shape stiffening rib 11 and constitute cyclic reinforcing rib 13, its muscle is high highly consistent with radial stiffening rib 12, and various reinforced ribs interconnect, and form space frame structure, can effectively improve the intensity of flywheel casing.
As shown in Figure 1, flywheel casing front-end face 1 top has rhone 5, offer the longitudinal drainage groove on the horizontal trunk stiffening rib on the front-end face 1, vertically have the transverse row tank on the trunk stiffening rib, groove depth is to the height of radial stiffening rib, can keep the continuous of trunk stiffening rib, and the ponding at top can be drawn along rhone.
As shown in Figure 3, because the constraint of arrangement space can't be arranged rib in the part, and this area planar is big, wall thin, easily produce cold diaphragm in the casting process, water production problems such as not saturating, if increase wall thickness then the weight increase, therefore, this zone design cellular structure 15, honeycomb is a regular hexagon, and the width and the degree of depth are less, and is little to the weight influence, this structure can not only improve intensity, but and can improve castability.
Flywheel casing of the present utility model provides a kind of flywheel casing that has air compressor actuation gear pinion barrel, and the casting integrated moulding of this pinion barrel and flywheel casing, and pinion barrel and the shared sidewall of flywheel casing can realize the air compressor postposition, saves the car load arrangement space; The design of the netted reinforcing rib on the flywheel casing can satisfied reduction complete machine weight on the intensity based; Cellular structure not only can improve intensity, also is convenient to casting; Design from discharge structure can effectively be discharged ponding.
More than disclosed only be a specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
