The lateral molded part of fork setting and oblique molded part, the transverse direction molded part and oblique molded part are interconnected by machining to be formed
Lateral oil duct and oblique oil duct, it is described transverse direction oil duct end be oil outlet, the lubricating oil pump pump housing by oblique oil duct with
The transverse direction oil duct is connected, which can be convenient for the processing of oil passageway.
Particularly, the balance shaft frame and the lubricating oil pump pump housing are all made of aluminum alloy materials and are made.
Particularly, several mounting holes for assembling entire frame are offered on the balance shaft frame.
Particularly, arc-shaped balance shaft mounting groove there are two being correspondingly arranged on the balance shaft frame, the balance shaft
Both ends be set in the balance shaft mounting groove, be fixed with arc-shaped limiting plate to balance shaft outside the balance shaft mounting groove
It is limited.
Particularly, the balance shaft frame is opened up in the both sides of the oil outlet there are two mounting hole, two fixing bolts
It is fixed in the mounting hole, so that machine oil circulation is smooth, prevents oil outlet from having oil leakage phenomenon.
Beneficial effects of the present invention are that the three-cylinder diesel can be changed engine oil pump assembly by lubricating oil pump compared with prior art
The pump housing and balance shaft frame integrally casting shaping, optimize the mounting means of lubricating oil pump and balance shaft, effectively reduce and start
Space shared by machine finally makes variable engine oil pump assembly lightweight, compact-sized.The two uses aluminum alloy materials, can be effective
The weight of engine is reduced, lubricating oil pump has the ability for reducing by 2~3% oil consumption using can be changed lubricating oil pump itself, and then apparent
Reduce the oil consumption of engine.
