Abstract
The invention discloses a left crankcase of a novel scooter engine. The left crankcase comprises a crankcase body, a balance shaft hole and a circular-arc retaining plate, a crank hole is formed in the crankcase body, a balance shaft hole is formed in the crankcase body and positioned beside the crank hole, and the circular-arc retaining plate is arranged on the inner surface of the crankcase body and semi-wrapped on one side, away from the crank hole, of the balance shaft hole. By adopting the above structure, the left crankcase is matched with a corresponding right crankcase, a balance shaft is mounted, extra increase of size of a crankcase is not needed, vibration and noise of the scooter engine are reduced effectively, and driving comfortableness is improved; a crank and the balance shaft are in gear transmission, and the circular-arc retaining plate is arranged and matched with a corresponding structure on the right crankcase, so that engine oil sputtering range when the balance shaft works is narrowed effectively.
Description
Technical field
The invention belongs to technical field of engines, be specifically related to the left 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.
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, will not additionally increase the left 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 left 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: balance axis hole, is arranged on described casing, is positioned at by described crankshaft hole;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.
Adopt above structure, left crankcase coordinates corresponding right 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, gear drive is adopted between bent axle and trunnion shaft, and by arranging circular arc baffle plate, and coordinate with the corresponding construction on right crankcase, effectively reduce machine oil sputtering scope during trunnion shaft work.
As preferably: be provided with drive mechanism integrated with it in the side of described casing and install case.Adopting above structure, integrated design to make its bonding strength higher, reliability is higher.
As preferably: the height of described circular arc baffle plate is concordant with the seamed edge of described casing.Adopt above structure, with the circular arc baffle fit on right crankcase, it is achieved control the effect of trunnion shaft machine oil splashing scope.
As preferably: be provided around reinforcement at described balance axis hole, its height is lower than the height of described circular arc baffle plate.Adopt above structure, be effectively increased the rigidity of whole casing.
Beneficial effect: adopt the left 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 circular arc baffle plate, effectively reduce the scope that when trunnion shaft rotates, machine oil splashes.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the invention will be further described.
As shown in Figure 1, a kind of left crankcase of Novel pedal car engine, including casing 1, this casing 1 is provided with crankshaft hole 2 and balance axis hole 3, wherein, it is other that balance axis hole 3 is positioned at described crankshaft hole 2, inner surface at described casing 1 arranges circular arc baffle plate 4 (in see Fig. 1 thick line portion), it partly wraps in the described balance axis hole 3 side away from described crankshaft hole 2, the height of this circular arc baffle plate 4 is concordant with the seamed edge 6 of described casing 1, coordinate the corresponding construction of right crankcase, effectively control the machine oil splashed when trunnion shaft rotates.
Referring to Fig. 1, be provided around reinforcement 7 at described balance axis hole 3, its height, lower than the height of described circular arc baffle plate 4, is effectively increased the rigidity of whole casing.
Referring to Fig. 1, be provided with integrated drive mechanism in the side of described casing 1 and install case 5, integrated design makes its bonding strength higher, and reliability is higher.
Finally need explanation; foregoing description is only the preferred embodiments of the present invention, and those skilled in the art is under the enlightenment of the present invention, under the premise without prejudice to present inventive concept and claim; can making and representing like multiple types, such conversion each falls within protection scope of the present invention.
