Problems solved by technology
The patent sets the transmission and the differential as an integral structure. Although the overall structural size is reduced and the structure is compact, it meets the design requirements of electric vehicles. However, this patent only solves the structural size problem, and does not solve the problem of power transmission and energy. The problem of large energy loss during the conversion process

The invention provides a two-gear speed changer with a magnetic powder clutch for an electric automobile, which belongs to the technical field of automobiles and solves the problems of loose structural connection, large structural size, high energy loss in power transmission and energy conversion processes of speed changers, differentials, motors and the like. The two-gear speed changer with the magnetic powder clutch for the electric automobile comprises an input shaft, an output shaft, the magnetic powder clutch, a differential, a speed changer processor and a current control unit, wherein the input shaft is connected with the output shaft through two pairs of speed change gear sets; a synchronizer by which the input shaft drives the output shaft to rotate only by one pair of speed change gear sets is arranged on the output shaft and is connected with an electromagnetic valve gear shift mechanism; and the electromagnetic valve gear shift mechanism and the magnetic powder clutch are directly controlled by the speed changer processor, so that the aims that the two-gear speed changer has a compact structure and saves energy sources are fulfilled.
Description
technical field [0001] The invention belongs to the technical field of automobiles, and relates to a transmission for an electric vehicle, in particular to a 2-speed transmission with a magnetic powder clutch for an electric vehicle. Background technique [0002] Today, as the number of cars is increasing and customers have higher and higher requirements for car technology, car technology has also been continuously developed. However, due to the aggravation of environmental pollution and the continuous rise of oil prices, people urgently need a new energy source and clean energy source to replace gasoline and fuel oil. As a green energy product, electric vehicles have become the development direction of automobiles because they are driven by electric energy, have a simple structure, low noise, low cost of use, and have good environmental protection effects. As an important structure of the vehicle transmission system, the transmission plays a role in the process of starting...
