Research on the nondestructive connection brake system for the transmission device test bench of armored vehicle

The nondestructive connection brake device is an important component of the high torque in-situ calibration system for the transmission test bench. The device enables nondestructive connection braking of the high torque drive shaft of armored vehicles. In order to ensure the accuracy of in-situ calibration on the premise of meeting the site space requirement, the researcher designed a nondestructive connection brake system which matches the high torque power output device on site. The system suits the narrow space on site and provides matching transmission shaft holding force on the basis of the transmission device test bench output torque, so as to precisely control the drive shaft holding force. With field test, the correlation between the output torque of transmission device test bench and holding force has been built, and the requirement of braking without damaging the transmission shaft has been met. The test results show that the designed nondestructive connection brake system can achieve nondestructive connection brake when the pure torque that drives the transmission shaft is lower than 30000 N·m.
