Highly effective energy-saving hub-type electric motorcycle

Abstract

A hub-typed high efficiency energy saving electric motorcycle consists of a vehicle frame, a hub motor driving wheel, a controller which is provided with an alternate charge and discharge control circuit and an operating handle. The hub motor driving wheel is arranged at the rear wheel of the rear vehicle frame of the motorcycle; the controller is arranged and fixed at one side of the rear wheel; the operating handle is arranged at the handle, wherein, the hub motor driving wheel consists of a brushless and toothless direct current motor of a permanent magnet disk type and a rim tire which is directly connected with a motor rotor; the number of the center wire grooves of the brushless and toothless direct current motor of the permanent magnet disk type can be decreased to 18 to the maximum extent; the visual power can have the different values from 18 to 54; the controller which is provided with the alternate charge and discharge control circuit is provided with a shell with large cooling fins and is firmly fixed at the stent of the controller by a bolt; the whole acceleration signal circuit and the brake signal circuit of the controller which is provided with the alternate charge and discharge control circuit are connected with the operating handle by a conductor.

Description

Technical field [0001] The invention relates to a motorcycle powered by a storage battery, in particular to a hub-type electric motorcycle with high power, high speed, high efficiency and energy saving. Background technique [0002] The speed of existing electric motorcycles is slow, generally 40-50km / h, and the continuation distance is short, especially the starting speed is even slower, which is still not up to the level of fuel motorcycles. The reason is well known that the power of the first motor cannot be reached, and the discharge current of the second battery cannot be reached. If the power of the motor is increased, the volume and weight must be increased, and if the discharge current of the battery is too large, the battery must be destroyed in a very short time. This is a problem that has plagued the scientific and technological circles for many years. A large number of new designs of electric motorcycles are far from touching these two major technical difficultie...

Problems solved by technology

The reason is well known, the power of the first motor cannot be reached, and the discharge current of the second battery cannot be reached. If the power of the motor increases, the volume and weight will inevitably increase, and if the discharge current of the battery is too large, the battery must be destroyed in a very short time.

This is a problem that has plagued the scientific and technological circles for many years. A large number of new designs of electric motorcycles are far from touching these two major technical difficulties. It is to press the DC permanent magnet geared high-speed motor on the rear wheel, and it is equipped with a self-generating controller, so that the motorcycle can recycle power when going downhill and coasting, but these measures are not enough to increase the speed and starting speed, and the result is an improvement. Afterwards, it is still no different from ordinary light massage
