Fixed-shaft-type side-hung power system for electric motorcycle

Abstract

The invention discloses a fixed-shaft-type side-hung power system for an electric motorcycle. The fixed-shaft-type side-hung power system comprises a flat fork, a reduction gearbox body, a motor, a fixed shaft, an output rotation sleeve and a transmission assembly, wherein, the reduction gearbox body is fixed to a main pipe of the flat fork, the motor is installed on one side of the reduction gearbox body, the fixed shaft penetrates through the reduction gearbox body, and the two ends of the fixed shaft are fixedly connected with corresponding main pipes; the output rotation sleeve is rotatably installed on the fixed shaft, extends from the interior of the reduction gearbox body to the exterior and is located between the two main pipes; and the transmission assembly can drive the output rotation sleeve to rotate under driving of the motor. By means of the fixed-shaft-type side-hung power system for the electric motorcycle, the structure is novel, achieving is easy, through design of the flat fork, the fixed shaft, the output rotation sleeve and a side-hung reduction gearbox, not only is the structure reliable, the safety is good, and comfortableness is good, but also the high-rotational-speed motor can be adopted, the torque of the electric motorcycle is improved effectively, and climbing performance is good.

Description

Technical field [0001] The invention belongs to the technical field of electric motorcycles, and in particular relates to a fixed-axis side-mounted power system for electric motorcycles. Background technique [0002] Compared with traditional motorcycles driven by internal combustion engines, electric motorcycles have the advantages of environmental protection, energy saving, good economy, and good comfort. Therefore, electric motorcycles are becoming more and more popular among the people, and their popularity in social life is increasing. improve. [0003] The gearbox of the traditional electric motorcycle adopts a mid-mounted gearbox. Although the structure is reliable and stable, it can only use a low-speed motor (the speed is about 400rpm) due to its own structure, which causes the torque of this electric motorcycle to be insufficient. The slope ability is poor and cannot meet the needs of people living in mountainous and hilly areas. Therefore, an electric motorcycle with a...

Problems solved by technology

However, this electric motorcycle has abandoned the flat fork due to its own structural design problems, and adopted a cantilever beam structure, and the output shaft directly drives the wheel hub of the electric vehicle to rotate (that is, the output shaft is in the form of a rotating shaft), but the cantilever beam One end is fixed on the reduction box only by bolt fastening or welding, which not only makes it difficult to align the output shaft and the cantilever beam when assembling, but also easily deforms the cantilever beam during long-term use, forcing the output shaft to bend and deform, causing shaft breakage, Problems such as oil leakage and increased working noise have seriously affected the safety and comfort of offset electric motorcycles
