Embodiment Construction

[0022] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment among various implementations of the present invention.

[0023] An engine balance housing, which further includes reinforced ribs and a hollowed-out weight-reducing structure, and has an oil baffle function structure, the balance shaft is installed in the shaft hole of the balance shaft housing, and the housing passes through the bolt hole 4. Fix the oil pump assembly, and install the rotating shaft of the oil pump in the hole. The oil pump supplies lubricating oil to the engine through the oil channel.

[0024] like Figure 1-3 As shown, the engine balance housing implemented by the present invention includes reinforcing ribs 1 for increasing strength; bolt holes 2 for fixing the oil pump; the oil pump provides lubricating oil through the oil channel 3-phase engine, and the oil pump drive shaft passes through the hole 5 and is driven by the o...

Abstract

The invention relates to a balance shaft case structure of an engine. The balance shaft case structure comprises a case body, a shaft hole, a reinforcing rib, a hollow structure, and an oil damper structure, wherein the reinforcing rib is arranged on the water wall of the case body for enhancing the balance shaft case structure; the hollow structure is arranged on the outer wall of the case body around the shaft hole for reducing the weight of the balance shaft case structure; the shaft hole is formed on the lower side of the case body and used for allowing the balance shaft to pass through and for mounting the balance shaft on the balance shaft case; and the oil damper structure is arranged on the upper side of the case body and used for preventing oil splashing. The balance shaft case structure provided by the invention is simple and compact in structure, and convenient in arrangement. After mounted on the engine, the balance shaft can rotate synchronously together with a crankshaft; a balancing weight on the balance shaft can counteract the rotation imbalance of the crankshaft caused by less number of cylinders of the engine, thereby reducing engine vibration and improving comfort of automobiles.

Description

technical field [0001] The invention belongs to the technical field of automobile engine manufacturing, and in particular relates to an engine balance shaft housing. Background technique [0002] In the case of increasingly tight oil energy supply, major automakers have turned to the development of energy-saving engines. The displacement of the engine is small, and its fuel consumption is relatively low. Compared with the widely used four-cylinder engine, the three-cylinder engine has significantly lower fuel consumption, so the three-cylinder engine is favored by many OEMs. Since the working principle of the engine itself is that each cylinder is ignited sequentially at different times to perform external work, the more cylinders there are, the more uniform the rotation will be, so when the three-cylinder engine is working, the vibration is much larger than that of the four-cylinder engine. For customers who are accustomed to four-cylinder and above engines, it is difficu...
