Two-gear electrical control variable speed motor for electric motorcycle

Abstract

The invention discloses a two-gear electrical control variable speed motor for an electric motorcycle. The motor comprises a motor stator, a motor shaft and a rotor which are arranged in a shell. A drive I-gear gear, a drive II-gear gear and an overrunning clutch are sequentially from right to left on the right part of the motor shaft. A central cam of the overrunning clutch is in fit connection with the motor shaft, and corresponds to an electromagnet arranged on the shell. A driven I-gear gear, a driven II-gear gear and a drive pinion are sequentially arranged from the right to the left on a central gear shaft. The driven I-gear gear is in fit connection with the central gear shaft by a one-way bearing, and is meshed with the drive I-gear gear arranged on the motor shaft. The driven II-gear gear is meshed with the drive II-gear gear idly sleeved on the motor shaft. The drive pinion is integrated with the central gear shaft, and is in fit connection with a drive bull wheel in fit connection with a drive shaft. The motor is organically combined with a gear shifting mechanism, the motor has a simple and compact structure, good radiation effects and long service life, and simply, conveniently and reliably realizes gear shifting operations.

Description

technical field [0001] The invention relates to electric motorcycle components, in particular to a two-speed electronically controlled variable speed motor of the electric motorcycle. Background technique [0002] Due to the pollution of the environment by the exhaust gas emitted by fuel motorcycles, in recent years, people have developed electric motorcycles that use batteries as energy sources. Such as hub type electric motorcycle, the drive motor of this electric motorcycle is installed in the center of rear wheel hub, directly drives rear wheel, though, does not consume fuel oil, is beneficial to environmental protection, but has following deficiency: the one, the uphill traction force is not enough, The second is that the driving speed on flat roads is slow. In order to overcome the defective that hub-type electric motorcycle exists, people have developed the electric motorcycle of mechanical speed change again, as the title of CN 200977974Y bulletin is called " a kind...

Problems solved by technology

Such as hub type electric motorcycle, the drive motor of this electric motorcycle is installed in the center of rear wheel hub, directly drives rear wheel, though, does not consume fuel oil, is beneficial to environmental protection, but has following deficiency: the one, the uphill traction force is not enough, Second, driving on flat roads is slow

Although the electric motorcycle can be shifted and adjusted mechanically, its structure is complex and not compact, the heat dissipation of the high-speed DC motor is poor, the service life of the motor is short, and the manufacturing cost is high.
