Abstract
The utility model relates to an internal combustion engine drive device and discloses a crankshaft and connecting rod assembly of a moped. The crankshaft and connecting rod assembly comprises a left crank, a right crank, a connecting rod, a crank pin and a needle bearing, wherein the left crank and the right crank are connected through the crank pin, and the connecting rod is connected with the crank pin through the needle bearing which is arranged between the connecting rod and the crank pin. The overall length of a crankshaft is 130-150mm, the eccentric distance of the crankshaft is 20-22mm, the center distance of the connecting rod is 88-92mm, the crank connection aperture is 16-20mm, the piston connection aperture is 12-16mm, and a spline is arranged on the left crank for outputting power. The crankshaft and connecting rod assembly of the moped is small in size and short in eccentric distance, and an engine is small in size, light in weight and small in engine capacity after being assembled by the crankshaft and connecting rod assembly of the moped. Further, a moped adopting the engine is light in total weight. Working fuel consumption is reduced.
Description
Technical field
The utility model relates to the internal-combustion engine transmission part, specifically is a kind of booster car crankshaft rod assembly.
Background technique
Motorcycle is sold on market as a kind of traffic tool.As motorcycle, general engine displacement is bigger, and the motor volume is also bigger simultaneously, and complete vehicle weight is also bigger.Because the Finished Motorcycle of motorcycle own wt is bigger, oil consumption is than higher when making car load work.In the flat-bottomed land or urban road, need a kind of advantages of small volume, the traffic tool that the car load own wt is lighter.
The model utility content
The purpose of the utility model is the booster vehicle engine crankshaft rod assembly that provides a kind of car load own wt lighter, in order to reduce the car load own wt, reduces the work oil consumption.
The purpose of the utility model is to realize like this: a kind of booster car crankshaft rod assembly comprises left crank, right crank, connecting rod, crank pin, needle bearing.The bent axle length overall is 130-150mm, throw of eccentric 20-22mm, and connecting rod centre distance is 88-92mm, and crank connects aperture 16-20mm, and piston connects aperture 12-16mm, on the left crankshaft spline is set.
The utility model crankshaft rod assembly size is less, and throw of eccentric is less, be assembled into motor after, the motor volume is little, and is in light weight, simultaneously engine displacement is also little.And then make the booster car complete vehicle weight of this motor of employing lighter.Reduced the work oil consumption.
