The comfort sailed, but due to scooter self structure, have strictly for engine volume size compared to motorcycle
Requirement, the scooter engine on the market does not design and is equipped with balance shaft at present, thus the scooter engine vibration is big, drives
Comfort is sailed to be affected.
Right crankcase is one of essential parts on the scooter engine, and right crankcase passes through spiral shell with left crankcase
Bolt, which is installed together, constitutes the scooter engine crankcase.Traditional scooter crankcase drives lubricating oil pump by sprocket wheel, long
Time is easily deformed upon using the chain of rear sprocket wheel.
Therefore, solving problem above becomes the task of top priority.
Invention content
In order to solve the above technical problems, the present invention provides a kind of with balance shaft, leads between bent axle, balance shaft and lubricating oil pump
Gear drive is crossed, the right crankcase of the Novel pedal car engine of box volume will not be additionally increased.
To achieve the above object, technical solution of the present invention is as follows：
A kind of right crankcase of Novel pedal car engine, including babinet, are provided with crankshaft hole, main points on the babinet
It is, further includes：Lubricating oil pump mounting portion is arranged on the babinet, is located at by the crankshaft hole；Axis hole is balanced, is arranged in institute
State on babinet, be located at by the crankshaft hole, between crankshaft hole be smaller than the lubricating oil pump mounting portion and crankshaft hole it
Between spacing；First circular arc baffle, is arranged the inner surface in the babinet, and half packet is in the balance axis hole far from the bent axle
The side in hole；Second circular arc baffle is arranged in the outer surface of the babinet, and half packet is in the lubricating oil pump mounting portion far from described
The side of crankshaft hole；First drain tap is arranged on the first circular arc baffle；And second drain tap, setting is described the
On two circular arc baffles.
Using the above structure, right crankcase coordinates corresponding left crankcase, is equipped with balance shaft, does not have to additional increase bent axle
The volume of case effectively reduces vibrations and the noise of the scooter engine, increases the comfort of driving, simultaneously because by bent axle,
The kind of drive between balance shaft and lubricating oil pump is improved to by gear drive, by being arranged the first circular arc baffle, and with left bent axle
Corresponding construction cooperation on case, machine oil sputtering range when effectively reducing balance shaft work, also by the way that the second circular arc baffle is arranged,
Effectively reduce machine oil pump work opportunity oil sputtering range.
As preferred：The first circular arc baffle contacts with babinet and forms separate cavities and oil back chamber on babinet, at this
Oil return hole is provided in oil back chamber.Using the above structure, the machine oil sputtered that the first circular arc baffle blocks is made to pass through oil return hole
It flows back.
As preferred：The fuel feed hole for being connected to the lubricating oil pump mounting portion is provided on the side of the babinet.Using
Oil charging structure need not be separately provided in the above structure on the lubricating oil pump pump housing, under the premise of ensureing that pump oil function is realized, reduce
The manufacturing cost of lubricating oil pump.
As preferred：The lubricating oil pump mounting portion is connected to the fuel feed hole by oil inlet passage.Using the above structure, it ties
Structure is simple, it is easy to accomplish.
Advantageous effect：Using the right crankcase of Novel pedal car engine provided by the invention, structure novel does not have to additional
The volume for increasing crankcase, effectively reduces vibrations and the noise of the scooter engine, increases the comfort of driving, pass through simultaneously
The setting of first circular arc baffle and the second circular arc baffle, the range that machine oil splashes when effectively reducing balance shaft and bent axle work.
Description of the drawings
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the rearview of Fig. 1.
Specific implementation mode
With reference to embodiment and attached drawing, the invention will be further described.
As depicted in figs. 1 and 2, a kind of right crankcase of Novel pedal car engine, including babinet 1, set on the babinet 1
It is equipped with crankshaft hole 2, balance axis hole 3 and lubricating oil pump mounting portion 4, wherein lubricating oil pump mounting portion 4 is located at the side of crankshaft hole 2, balance
Axis hole 3 also is located at the side of crankshaft hole 2, balance between axis hole 3 and crankshaft hole 2 be smaller than the lubricating oil pump mounting portion 4 with
Spacing between crankshaft hole 2, after bent axle, balance shaft and lubricating oil pump install gear respectively, the gear band dynamic balancing axis on bent axle
On gear rotation, the gear rotation on the gear band motivation oil pump in balance shaft.Be provided on the side of the babinet 1 into
Oilhole 12, the lubricating oil pump mounting portion 4 are connected to the fuel feed hole 12 by oil inlet passage 13, make in lubricating oil pump not having to again individually
