Description
Technical field
The present invention relates to a kind of balance shaft system of engine.
Background technique
Balance system of engine if vehicular engine produces vibration, will impair the smoothness and the travelling comfort of automobile for the device of the second order vibromotive force of the piston generation of elimination motor, quickens driver's fatigue, influences traffic safety.In addition, vibration causes noise, consumed energy, and the total efficiency of reduction machine, vibration also may cause the loosening and overload of fastening connection piece, reduces the durability of unit.Therefore the research of engine balance is very important project in the current engine technology.
In now a lot of balance sysmte arrangements, balance sysmte is arranged in the oil sump comparatively general.It is bigger to the machine oil disturbance that but the built-in balance shaft system of oil sump exists, and lubrication system is produced the rough sledding of certain influence, can produce rotational resistance to trunnion shaft in the enclosure because a large amount of lubricant oil is detained simultaneously.In addition, balance sysmte is arranged in the design difficulty that has increased engine sump tank in the oil sump, has increased the volume of oil sump, car load is arranged brought difficulty.
Summary of the invention
The technical problem to be solved in the present invention is, in order to remedy the deficiency of available engine balance sysmte, and provides a kind of balance system of engine simple in structure, favorably situated.
Further aim of the present invention provides a kind of lubricated balance system of engine preferably.
The present invention solves the problems of the technologies described above to adopt following technological scheme:
A kind of balance shaft system of engine comprises the trunnion shaft that is arranged on the engine cylinder-body frame assembly, and driving gear is arranged on the trunnion shaft, and the trunnion shaft two ends connect back balance respectively and heavily reach forward horizontal stand heavily; It is characterized in that: trunnion shaft places cylinder body frame assembly one side; Live axle also is set on cylinder body frame assembly, driving gear and driving pulley are set on the live axle; Driving gear engagement trunnion shaft upper transfer gear, driving pulley is by the engine timing system belt drives.
Described trunnion shaft is the axle hollow structure, and oil inlet hole, oil outlet are arranged above it; Extrude lubricant oil in the oil supply hole in the oil leab on the cylinder body frame assembly, step bearing before the earlier lubricated on the one hand balance shaft system enters oil inlet hole simultaneously to the lubricated balance shaft system rear end bearing of oil outlet.
Describedly front cover and side cover cap are set respectively, and constitute a seal with cylinder body frame assembly at balance shaft system.
It mainly is its air inlet side that is arranged in engine cylinder-body frame assembly that the present invention is different from traditional arrangement, constitute a seal by balance sysmte front cover and balance sysmte side cover cap and cylinder assembly, oil duct by cylinder assembly provides pressure lubrication oil, and trunnion shaft is lubricated.
Working principle of the present invention is: native system comprises two axle systems, driving pulley drives by the engine timing system belt, produce rotary driving force, drive the rotation of balance sysmte live axle, simultaneously, the live axle driving gear that is fixed on the live axle passes to the trunnion shaft driving gear with the rotating force of live axle, this moment, trunnion shaft rotated with speed with live axle under the effect of driving force, forward horizontal stand is heavy to focus on the drive rotation down of trunnion shaft with back balance, thereby reaches the second order vibromotive force effect that engine piston produces of eliminating.In the balance sysmte working procedure, its lubricant oil is that the oil duct by cylinder body frame assembly provides, the pressure that utilizes engine lubrication system to produce extrudes lubricant oil from the balance sysmte oil supply hole, lubricate step bearing before the balance sysmte along the balance sysmte oil duct on the cylinder body frame assembly.Simultaneously, trunnion shaft is designed to the axle center hole structure, parts of lubricating oil is pressed onto the balance shaft system rear end by its axle center hole, its rear end bearing is lubricated from the outflow of trunnion shaft the other end oil outlet by the trunnion shaft oil inlet hole.The lubricant oil that has lubricated bearing can flow in the oil sump along the spill port on the cylinder body frame assembly, enters next greasing.
Good effect of the present invention is, owing to adopt trunnion shaft to place cylinder body frame assembly one side; The present invention is applicable to that all use balance sysmtes to eliminate the motor of the second order vibromotive force that engine piston produces, and its distinguishing feature is summarized as follows: 1. compact structure, simplified the design of engine sump tank, and reduced the height of motor; 2. it is obvious to eliminate piston second order vibromotive force; 3. do not upset the lubricant oil in the oil sump, lubrication system is not had upset.4. the trunnion shaft lubricating oil path is reasonable in design.
