The present invention discloses a retarder for a transportation device. According to the present invention, two magnetic retarder assemblies I and II arranged symmetrically are used to achieve retardance of a transmission shaft with a good retardance effect, so that the retardance effect can be significantly improved and the stability retardance of the transmission shaft can be enhanced, thereby allowing application to large transportation equipment. In addition, a controller may determine whether to enable an auxiliary retarding assembly according to a retardance requirement, and after the auxiliary retarding assembly is enabled, further braking of the retarder assembly I and the retarder assembly II can be achieved, thereby improving the retarding braking performance. The retarder for atransportation device can significantly improve the retardance effect and can meet the retardance requirements of large transportation equipment. Additionally, the auxiliary retarding assembly of theretarder for a transportation device is also provided with a cooling liquid, so that the cooling effect of a brake disc can be ensured, thereby guaranteeing the service life of the brake disc.
Description
technical field [0001] The invention relates to a deceleration device for a transportation device, which belongs to the technical field of transportation auxiliary equipment. Background technique [0002] For transportation equipment, especially for transportation equipment that often travels in mountainous or hilly areas, in order to reduce or maintain a stable vehicle speed for a long time and reduce or release the load on the service brake when going down a long slope, it is usually necessary to install a brake. Auxiliary braking devices such as speed reducers, generally, traffic devices with a total mass of more than 5t, especially transportation equipment with a total mass of more than 12t, need to be equipped with this auxiliary braking deceleration device. [0003] According to the relevant provisions of the national standard GB12676-1999 "Automobile Braking System Structure, Performance and Test Methods", for M3 passenger cars with a maximum total mass greater than 1...
