Abstract

The invention relates to the technical field of automobile manufacturing and discloses a dynamic testing device for a temperature of a steel disc of a clutch, a wet clutch assembly and a four-wheel drive transfer case. The dynamic testing device for the temperature of the steel disc of the clutch is mounted on the wet clutch and is rotatably mounted in the four-wheel drive transfer case along withthe wet clutch. The dynamic testing device for the temperature of the steel disc of the clutch comprises a temperature sensor, an emitter module and a power supply and transfer module. The temperature sensor is fixed to the steel disc of the clutch, the emitter module is fixed to a rotating tool and the power supply and transfer module is mounted on the four-wheel drive transfer case. The temperature sensor and the emitter module are electrically connected through a wire, and the power supply and transfer module is electrically connected to the emitter module wirelessly. According to the dynamic testing device for the temperature of the steel disc of the clutch, the wet clutch assembly and the four-wheel drive transfer case, the temperature of the steel disc of the clutch can be tested dynamically in an actual moving state, and a test result is precise.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a clutch steel plate temperature dynamic testing device, a wet clutch assembly and a four-wheel drive transfer case. Background technique [0002] The wet clutch has always been the key core component in the whole vehicle, and its development is extremely difficult, especially the preparation of friction materials is very difficult. The wet clutch is installed in the four-wheel drive transfer case and rotates with the input shaft of the four-wheel drive transfer case. The fluctuation range of its speed and working oil temperature is relatively large, and the speed range of the wet clutch is between 0 and 8000r / min. , The working oil temperature range is -40 ℃ ~ 120 ℃. [0003] The accurate calibration of the clutch steel plate temperature model can provide core data support for the torque distribution of the four-wheel drive transfer, vehicle dynamics, economy a...
