Problems solved by technology
[0003] At present, the retarders used in the domestic automobile industry have the defects of large volume, heavy weight, and high energy consumption and electricity consumption. Under the condition of the same torque, that is, the torque is 2200 Nm, the weight of domestic retarder products is between 220 and Between 310 kg, the fuel consumption is relatively large; when the current is between 95 and 170 amperes, the power consumption is relatively large, and it also brings great inconvenience to the repair and maintenance of the vehicle

Embodiment Construction
[0010] An energy-saving eddy current retarder, including a stator 10 and a rotor assembly 20, a coil 13 is arranged on the stator 10, the stator 10 is fixed on the vehicle through a bracket 30, and the rotor assembly 20 is connected with a transmission shaft 50, as shown in Figure 1 As shown, the power supply 70 energizes the coil 13 of the stator 10 through the inverter 80, and the function of the inverter 80 is to convert the DC input into an AC output, increase the magnetic force to achieve a large torque, slow and stable braking effect, and at the same time , balance current, reduce fuel consumption.
[0011] The input terminal of the inverter 80 is connected to the power supply 70. In the present invention, a DC power supply of 24V is selected, and the output terminal of the inverter 80 is connected to the input terminal of the speed controller 90 and the bases of at least two transistors Q respectively. The output terminals of the speed controller 90 are respectively con...

The invention relates to an energy-saving electric eddy current retarder, which consists of a stator and a rotor assembly. A coil is arranged on the stator which is fixed on vehicles through a support. The rotor assembly is connected with a transmission shaft. The coil of the stator is electrified through an inverter by the electric power source. By adding the inverter in a control circuit, the invention changes input of direct current into output of alternating current; third grade tube is enlarged, voltage is increased; magnetic force is increased; torque is increased; braking effect is obvious and retarding is steady. At the same time, electric current is balanced and electricity consumption is reduced. Furthermore, the invention lightens weight of the rotor and reduces oil consumptionconsequently.
Description
technical field [0001] The invention relates to an automobile accessory, in particular to an energy-saving electric eddy current retarder. Background technique [0002] The eddy current retarder is a device that uses the principle of electromagnetism to convert the kinetic energy of the vehicle into heat and dissipate it, thereby achieving deceleration and braking. Compared with the traditional braking, the eddy current retarder has many advantages: it greatly improves the braking performance of the car, improves the safety and smoothness of the car driving, and reduces the loss of life and property; eliminates the sharp noise and dust during traditional braking. Environmental pollution; save vehicle maintenance costs and the accompanying loss of time for repairs, prolong the service life of brake pads and tires, improve economic benefits, etc. [0003] At present, the retarders used in the domestic automobile industry have the defects of large volume, heavy weight, and hig...
