推土机主离合器的工作质量,直接关系到整机的质量。主离合器摩擦力矩技术性能的测定是很重要的。推土机主离合器所能产生的摩擦力矩,克服整机运行和生产中的阻力,以保证其正常作业。主离合器产生的摩擦力矩,应为其柴油机输出力矩的1.5～3倍(储备系数β=1.5～3)。T120型推土机柴油机的输出力矩为57.3Kgf·m,故主离合器的摩擦力矩应保证产生86～171.9Kgf·m的摩擦力矩,否则会打滑而无法正常运行。为了测定主离合器所能产生的摩擦力矩,
The working quality of the bulldozer’s main clutch is directly related to the quality of the whole machine. The determination of the technical performance of the main clutch friction torque is very important. The friction torque that can be produced by the bulldozer’s main clutch overcomes the resistance of the whole machine during operation and production to ensure its normal operation. The friction torque produced by the main clutch should be 1.5 to 3 times the output torque of the diesel engine (reserve factor β = 1.5 to 3). The output torque of the T120 bulldozer diesel engine is 57.3Kgf·m, so the friction torque of the main clutch should be guaranteed to generate a friction torque of 86～171.9Kgf·m, otherwise it will slip and fail to operate normally. In order to measure the friction torque that the main clutch can produce,
