Problems solved by technology

It can be known from dynamics that the inertial energy of a wheel depends on its speed and mass. Due to the limitation of the speed of the car, the speed of the wheel shaft cannot be very high, generally below 1000 revolutions per minute. The inertial energy generated cannot be released and recovered quickly, which affects the energy recovery rate to a certain extent
In addition, since the transmission part is installed on the wheel shaft

Abstract

The invention provides a device and method for recovering the inertial energy of automobile wheels, belonging to the fields of automobile energy saving and emission reduction and new energy electric vehicles. The invention adds a fixed internal gear insert on the inner ring of the automobile wheel hub. When the automobile wheel rotates, the power increases through the internal gear transmission mechanism and directly drives the permanent magnet synchronous generator to generate electricity, which is generated by the brake pedal sensor and the tire speed sensor. The signal controls the opening and closing of the electromagnetic clutch, which directly drives the permanent magnet synchronous generator to generate electricity. At the moment of braking and deceleration of the car, it can quickly release and recover the inertial energy of the car wheels in large quantities, and provide power to the battery or the power network of the whole vehicle. The device has the advantages of simple structure, small volume, high energy recovery rate, good reliability, low manufacturing cost, and certain technical and economic feasibility.

Description

technical field [0001] The invention relates to a device and method for recovering the inertial energy of automobile wheels, and belongs to the technical fields of automobile energy saving and emission reduction and new energy electric vehicles. Background technique [0002] When the car is running on the road, at least one-third of the energy of the fuel engine or the driving motor of the electric car is used to overcome the rolling resistance of the car wheels, and the resistance of this part is proportional to the mass of the car itself and the speed of driving . When a car brakes, coasts or decelerates, this creates a huge amount of inertial energy. With the shortage of energy and the increasing attention to the environment in the world, how to effectively recover this part of inertial energy not only has certain economic benefits, but also has certain social significance. [0003] Attempts have long been made to store a car's inertial energy indirectly by installing a...
