Abstract

The invention belongs to the technical field of military crawler-type vehicles and various crawler-type armored vehicles, and particularly relates to a method for measuring the torque of a cooling fanof a crawler-type vehicle. Compared with the prior art, the invention provides a reliable test method aiming at the structural characteristics of high compactness and high rotating speed of a fan rotating shaft and the working environment, a fan torque sensor and the test system realize high integration of the sensor, a test circuit and a tested part through miniaturization and micro-power consumption design, and the torque of the cooling fan can be conveniently and rapidly measured. The method is of great significance in overall design of crawler-type military vehicles and engineering vehicles and determination of the torque of the cooling fan under different working conditions, the power transmitted to the fan can be calculated through measurement of the torque of the cooling fan, and therefore the model selection of a vehicle overall designer about a power device is more accurate.

Description

technical field [0001] The invention belongs to the technical field of military tracked vehicles and various tracked armored vehicles, and particularly relates to a method for measuring the torque of a cooling fan of a tracked vehicle. Background technique [0002] The space near the fan shaft of the tracked vehicle is small, the temperature is high, and the shaft is in constant motion, so it is difficult to measure and measure accurately.
