Electromechanical converter system for electric vehicles

Abstract

The invention relates to a converter system (1, 1', 1'') for an electric vehicle and in particular a lightweight electric vehicle. The converter system (1, 1', 1'') has a supporting housing (10, 10', 10'') for connecting to the vehicle, has an electromechanical energy converter arranged at least partially in the supporting housing (10, 10', 10''), said electromechanical energy converter having at least one stator (21, 21') and a rotor (22, 22') which is rotatable relative to the stator (21, 21') about a drive axis (7, 40), and has a power transmitting device which connects the rotor (22, 22') to a connection element. To permit a particularly cheap design which is easy to maintain and to reduce thermal problems,

Description

technical field

[0001] The invention relates to an electromechanical conversion system for an electric vehicle, in particular for a light electric vehicle. Background technique

[0002] Electrical or electromechanical conversion systems for vehicles are variously known in the prior art and are used, for example, to convert electrical energy for driving so-called electric vehicles into mechanical drive energy. In another application, electromechanical conversion systems are used in vehicles to generate electrical energy from mechanical work. This includes, for example, vehicle generators that generate electrical energy from the work of the internal combustion engine for feeding electric wheel drives (range extenders).

[0003] Due to rising energy prices, in the near future various vehicle types, such as electric vehicles, have continued to be developed, but new types have also been proposed, especially in the field of light electric vehicles. In addition to electric bicycl...
