Abstract

The invention discloses a novel right crank case of a scooter engine. A case body is provided with a crankshaft hole, a balance shaft hole and an engine oil pump installation base, wherein the engine oil pump installation base is located on one side of the crankshaft hole, the balance shaft hole is located in one side of the crankshaft hole, and the distance between the balance shaft hole and the engine oil pump installation base is smaller than the distance between the crankshaft hole and the engine oil pump installation base; and a first arc baffle is arranged on the inner surface of the case body and arranged on one side, far away from the crankshaft hole, of the balance shaft in a semi-wrapping manner, and a second arc baffle is arranged on the outer surface of the case body and arranged on one side, far away from the crankshaft hole, of the engine oil pump installation base in a semi-wrapping manner. A first oil drainage opening is formed in the first arc baffle, and a second oil drainage opening is formed in the second arc baffle. By means of the above structure, the novel right crank case is novel in structure, the size of the crank case does not need to be increased additionally, vibration and noise of the scooter engine are effectively reduced, and the driving comfort is improved; and meanwhile, through the arrangement of the first arc baffle and the second arc baffle, the splashing scope of engine oil when a balance shaft and a crankshaft work is effectively shrunk.

Description

The right crankcase of Novel pedal car engine
Technical field
The invention belongs to technical field of engines, be specifically related to the right crankcase of a kind of Novel pedal car engine.
Background technology
Scooter is a kind of vehicle between motorcycle and automobile, is a kind of popular vehicles.Trunnion shaft is widely used in motorcycle engine, it simple and practical, can effectively extenuate the car load vibration of motorcycle, improve the comfortableness driven, due to scooter self structure, comparing motorcycle has strict requirement for electromotor volume size, and all non-design and installation of the scooter engine on the market at present has trunnion shaft, thus the scooter engine vibration is big, driver comfort is affected.
Right crankcase is one of requisite parts on the scooter engine, and right crankcase is installed together composition the scooter engine crankcase with left crankcase by bolt.Traditional scooter crankcase passes through chain wheel drive lubricating oil pump, and after long-time use, the chain of sprocket wheel very easily deforms upon.
Therefore, solve problem above and become the task of top priority.
Summary of the invention
For solving above technical problem, the present invention provides one to have trunnion shaft, by gear drive between bent axle, trunnion shaft and lubricating oil pump, will not additionally increase the right crankcase of the Novel pedal car engine of box volume.
For achieving the above object, technical solution of the present invention is as follows:
The right crankcase of a kind of Novel pedal car engine, including casing, is provided with crankshaft hole on this casing, and it is characterized by, and also includes: lubricating oil pump installation portion, is arranged on described casing, is positioned at by described crankshaft hole;Balance axis hole, is arranged on described casing, is positioned at by described crankshaft hole, the spacing being smaller than between described lubricating oil pump installation portion and crankshaft hole between itself and crankshaft hole;First circular arc baffle plate, is arranged on the inner surface of described casing, and it partly wraps in the described balance axis hole side away from described crankshaft hole;Second circular arc baffle plate, is arranged on the outer surface of described casing, and it partly wraps in the described lubricating oil pump installation portion side away from described crankshaft hole;First drain tap, is arranged on described first circular arc baffle plate;And second drain tap, it is arranged on described second circular arc baffle plate.
Adopt above structure, right crankcase coordinates corresponding left crankcase, trunnion shaft is installed, need not additionally increase the volume of crankcase, effectively reduce vibrations and the noise of the scooter engine, increase the comfortableness of driving, simultaneously because the kind of drive between bent axle, trunnion shaft and lubricating oil pump is improved to by gear drive, by arranging the first circular arc baffle plate, and coordinate with the corresponding construction on left crankcase, effectively reduce machine oil sputtering scope during trunnion shaft work, also by arranging the second circular arc baffle plate, effectively reduce machine oil sputtering scope during lubricating oil pump work.
As preferably: described first circular arc baffle plate and casing are separated to form separate cavities and oil back chamber from top to bottom, are provided with spill port in this oil back chamber.Adopt above structure, make the machine oil sputtered of the first circular arc baffle plate closure be refluxed by spill port.
As preferably: be provided with the fuel feed hole being communicated to described lubricating oil pump installation portion on the side of described casing.Adopt above structure, the lubricating oil pump pump housing need not be separately provided oil charging structure, under ensureing the premise that pump functional oil realizes, reduce the manufacturing cost of lubricating oil pump.
As preferably: described lubricating oil pump installation portion is connected by oil inlet passage with described fuel feed hole.Adopt above structure, simple in construction, it is easy to accomplish.
As preferably: the height of described first circular arc baffle plate is concordant with the seamed edge of described casing.Adopt above structure, with the circular arc baffle fit on left crankcase, it is achieved the machine oil that closure trunnion shaft sputters when rotating.
Beneficial effect: adopt the right crankcase of Novel pedal car engine provided by the invention, novel structure, need not additionally increase the volume of crankcase, effectively reduce vibrations and the noise of the scooter engine, increase the comfortableness of driving, simultaneously by the setting of the first circular arc baffle plate and the second circular arc baffle plate, the scope that when effectively reducing trunnion shaft and bent axle work, machine oil splashes.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention;
Fig. 2 is the rearview of Fig. 1.
Detailed description of the invention
Below in conjunction with embodiment and accompanying 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 casing 1, this casing 1 is provided with crankshaft hole 2, balance axis hole 3 and lubricating oil pump installation portion 4, wherein, lubricating oil pump installation portion 4 is positioned at the side of crankshaft hole 2, balance axis hole 3 also is located at the side of crankshaft hole 2, the spacing being smaller than between described lubricating oil pump installation portion 4 and crankshaft hole 2 between balance axis hole 3 and crankshaft hole 2, bent axle, after trunnion shaft and lubricating oil pump are respectively mounted gear, the pinion rotation on gear driven trunnion shaft on bent axle, the pinion rotation in gear driven lubricating oil pump on trunnion shaft.Being provided with fuel feed hole 12 on the side of described casing 1, described lubricating oil pump installation portion 4 is connected by oil inlet passage 13 with described fuel feed hole 12, makes need not be separately provided in lubricating oil pump oil charging structure again.
