Electric starting mechanism of pedal motorcycle engine

Abstract

The invention relates to an electric starting mechanism of a pedal motorcycle engine. The electric starting mechanism comprises a starting clutch arranged on a journal at the front end of a crankshafton the left side of the engine. An inner hole of the starting clutch is in splined connection with the journal at the front end of the crankshaft and is pressed on a shaft shoulder at the front end of the crankshaft through a gasket sleeve. Outer teeth of the starting clutch are connected with an output shaft of a starting motor through a duplicate gear. The starting clutch is located on the outer side of the left end of a left box body of a crankshaft box of the engine. A timing chain is arranged between the starting clutch and the left box body of the crankshaft box. An oil isolation disc is arranged on the left side of the starting clutch. A closed cavity is formed by the oil isolation disc and the left box body of the crankshaft box. The electric starting mechanism has the beneficialeffects that the electric starting mechanism is simple in structure and convenient to mount and maintain; due to the fact that the starting clutch is lubricated sufficiently, wear of the clutch is reduced, the reliability of the clutch is improved, and the failure rate of the engine is obviously reduced; and the problems existing when the electric starting clutch is arranged on the left side of the engine are solved well.

Description

technical field [0001] The invention relates to motorcycle engine technology, in particular to an electric starting mechanism for a scooter engine. Background technique [0002] The engine cannot turn from static to working state by itself, and the crankshaft must be rotated by external force until the crankshaft reaches the speed necessary for the engine to start burning, so that the formation, compression and ignition of the mixture can be ensured smoothly. The electric starting mechanism on the left side of the domestic scooter engine is dry type, as shown in the attached drawing of the manual figure 1 As shown, since the starting clutch is in an open environment without lubricating oil cooling, it is relatively easy to damage, and the market feedback has a high failure rate. Therefore, most domestic scooter engines are arranged with the right oil bath type electric starter mechanism, as shown in the attached drawing of the manual figure 2 As shown, this causes the size...

Problems solved by technology

[0003] The purpose of the present invention is to propose an electric starting mechanism for a scooter engine. The oil-bath electric starting mechanism is arranged on the left side of the engine, which not only reduces the size of the right side of the engine, but also solves the problem of the current domestic dry-type electric starting mechanism on the left side. The problem of poor institutional reliability
