Energy-saving self-excitation type retarding device

Abstract

The invention discloses an energy-saving self-excitation type retarding device. The energy-saving self-excitation type retarding device comprises a self-excitation type retarder, a vehicle transmission shaft and a generator shaft. The retarder mainly comprises a retarder rotor disc, a retarder iron core and a retarder coil, and the self-excitation type retarder and a connector of the generator shaft are installed on the vehicle transmission shaft. When a vehicle brakes, the retarder iron core is driven to rotate by energy of motion of the running vehicle, so that an eddy current braking torque is generated on the retarder rotor disc. Besides, the energy of motion of the running vehicle is further used for driving the generator shaft to rotate, so that the energy of motion is transformed to electric energy and is stored in a storage battery through the work of a generator. According to the energy-saving self-excitation type retarding device, combined actions of retardance mechanisms of two types are adopted, so that the braking effect of the vehicle can be effectively and reliably guaranteed, and the aims of energy storage and energy saving are achieved. The energy-saving self-excitation type retarding device is reasonable in distribution, simple in structure, convenient to maintain and suitable to be installed and used in a motor bus and an electric car.

Description

technical field [0001] The invention belongs to the field of self-excited retarders, in particular to an energy-saving self-excited retarder. Background technique [0002] As people pay more and more attention to the energy saving, environmental protection and driving safety of automobiles, how to better improve the energy saving and emission reduction effect and safety of vehicles has become the relentless goal pursued by more manufacturers. In terms of vehicle braking and energy saving, traditional mechanical friction brakes rely on frequent or long-term mechanical friction to brake. During the friction braking process, not only a large amount of toxic dust is generated, but also brake drums (discs) and friction plates are damaged. (Brake lining) is overheated, causes braking efficiency to decline even brake failure, and this kind of braking system all needs to be further improved in terms of energy saving, environmental protection and safe driving performance. The instal...

Problems solved by technology

At present, the retarders with relatively mature technology and suitable for loading include hydraulic retarders, eddy current retarders, permanent magnet retarders, etc. However, they also have disadvantages, such as large volume and weight of hydraulic retarders, The braking response is slow, and the braking force is greatly affected by the vehicle speed; the eddy current retarder is slightly inferior in terms of energy saving; the permanent magnet retarder has a small braking torque and cannot be adjusted

[0004] The existing retarder only achieves the braking effect, and has not considered how to further convert the kinetic energy of the vehicle into electrical energy and store it to achieve the purpose of energy saving
