摘　　要：为掌握永磁式涡流缓速器与排气制动的联合制动在车辆上的实际制动能力,对永磁式涡流缓速器和排气制动特点进行了分析,采用道路试验和理论分析相结合的方法,从平路减速距离和坡道稳定持续下坡车速与坡度关系两个方面考察永磁式涡流缓速器与排气制动联合制动的制动能力。结果表明:在平路上,使用联合制动能在更短时间内减低车速,有效缩短减速距离;在坡道上,使用联合制动可以保证车辆在更大坡度坡道上(5.5%～9.0%)以安全、经济的车速稳定下坡行驶。上述研究对于促进永磁式涡流缓速器和排气制动装置在国内车辆上的装用具有参考作用。In order to investigate the practical braking ability of united brake system with permanent magnet type eddy current retarder and exhaust brake in vehicle,the advantages and disadvantages of permanent magnet type eddy current retarder and exhaust brake were analyzed,respectively.The experiments and theoretical analysis on the braking ability of united brake with permanent magnet type eddy current retarder and exhaust brake for vehicle were carried out under the conditions of level roads and hillside paths.The results show that the united brake can make the braking distance shortened,the deceleration increased,the braking ability of the vehicle improved on the level road,and the united brake system can meet the demands for vehicle to travel on steeper slope at steady and economic speed.All of above that can provide reference for application of the permanent magnet type eddy current retarder and exhaust brake in vehicle.
