Abstract

The invention discloses an installing structure of an internal oil pump of an electric-jet motorcycle. An assembling hole (1a) is arranged at the middle part of the top surface of an auxiliary oil tank (1); a positioning plate (3) is fixed on the top surface of the auxiliary oil tank (1); a positioning ring (1b) is formed on the part of the top surface of the auxiliary oil tank (1) between the positioning plate (3) and the assembling hole (1a); a plurality of studs (4) are vertically fixed on the positioning plate (3); the lower end of an oil pump (2) penetrates through the assembling hole (1a) and extends into the auxiliary oil tank (1); the upper end of the oil pump (2) is provided with a positioning disc (2a) which is supported by the positioning ring (1b) and is provided with an installing plate (5) in a pressing manner; and the studs penetrate through corresponding via holes on the installing plate (5) and are locked by nuts. The installing structure not only beautifies the appearance of the auxiliary oil tank and the whole motorcycle, but also is firm and reliable in installation, is convenient to operate in disassembly and assembly of the oil pump, can greatly improve the disassembling and assembling efficiency and is beneficial to fast check and maintenance.

Description

technical field [0001] The invention belongs to the technical field of electric jet motorcycles, and in particular relates to the installation structure of the built-in oil pump of electric jet motorcycles. Background technique [0002] The oil pump is a very important part on the EFI motorcycle. At present, the oil pump on the EFI motorcycle generally adopts an external installation method. Such as Figure 7 , Figure 8 As shown, a bracket is welded at the left front corner of the auxiliary fuel tank 1, and an assembly hole is opened on the bracket, and lugs are provided on the oil pump 2, and holes are opened on the lugs, and bolts pass through the through holes on the lugs and on the bracket. Fix the oil pump 2 on the auxiliary fuel tank 1 through the assembly hole. The oil pump is installed externally. On the one hand, it will easily affect the appearance of the auxiliary fuel tank and the motorcycle. On the other hand, the oil pump occupies a large space, which is ea...
