Problems solved by technology
In the current existing technology, the balance shaft mechanism is usually arranged under the crankshaft or on the side of the cylinder block, and the oil pump is often arranged coaxially with the crankshaft, which leads to the relatively scattered arrangement of the internal components of the engine, resulting in the engine itself. The structure is not compact, and the overall space The size is large, which is not conducive to the layout of the whole vehicle

Embodiment Construction
[0025] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.
[0026] like Figure 1 to Figure 6 As shown, the present disclosure provides a balance shaft housing, including a housing body 1 for rotatably supporting the balance shaft 2 , wherein the front end of the housing body 1 arranged along the axial direction of the balance shaft 2 is integrated with an oil pump 3 . That is, the oil pump 3 and the balance shaft housing 1 originally arranged coaxially with the engine crankshaft are integrated together, and since the front and rear length of the balance shaft housing itself is smaller than the length of the crankshaft itself, the space size of the engine is thus reduced , so that the overall structure of the engine...

The invention relates to a balance shaft shell, a balance shaft assembly and an engine. The balance shaft shell comprises a shell body (1) used for supporting a balance shaft (2) in a rotating manner.An engine oil pump (3) is integrated at the front end, arranged in the axial direction of the balance shaft (2), of the shell body (1). The shell body (1) is provided with a lubricating oil channel (4). The lubricating oil channel (4) comprises an oil input channel (41) used for communicating with an oil cavity (33) of the engine oil pump (3), and an oil supply channel (42) used for supplying oilto the shaft neck of the balance shaft (2). The oil input channel (41) and the oil supply channel (42) communicate mutually. The balance shaft shell integrated with the engine oil pump enables the structure of an engine to be more compact, the space size of the engine is reduced, then the whole vehicle can be arranged conveniently, and the engine oil pump can be utilized for supplying the oil tothe balance shaft.
Description
technical field [0001] The present disclosure relates to the field of engine parts, in particular, to a balance shaft housing, a balance shaft assembly and an engine. Background technique [0002] With the continuous development of automobile technology, adding a balance shaft mechanism to the engine has become a technical trend to meet market demand. The NVH performance of the engine and the vehicle can be improved by adding a balance shaft mechanism. In the current existing technology, the balance shaft mechanism is usually arranged under the crankshaft or on the side of the cylinder block, and the oil pump is often arranged coaxially with the crankshaft, which leads to the relatively scattered arrangement of the internal components of the engine, resulting in the engine itself. The structure is not compact, and the overall space The size is large, which is not conducive to the layout of the whole vehicle. Contents of the invention [0003] An object of the present disc...
