Clutch thermal capacity testing device

Abstract

The invention discloses a clutch thermal capacity testing device. The clutch thermal capacity testing device comprises a front shell, a rear shell, an input flange, an output flange and a temperature sensor; a clutch assembly is rotatably mounted in the front shell, an input hub of the clutch assembly is connected with the input flange through an input shaft, and an output hub of the clutch assembly is connected with the output flange through an output shaft; and a slip ring support is rotatably mounted on the output shaft, a connecting plate is fixedly mounted on the slip ring support, the connecting plate is connected with an outer hub spline of the clutch assembly, a conductive slip ring is further mounted on the slip ring support, the temperature sensor is fixedly arranged on the disc surface of the connecting plate, and a wiring harness of the temperature sensor is connected with the conductive slip ring. The clutch thermal capacity testing device can carry out more accurate thermal capacity testing on the clutch assembly, is high in centering precision, and prevents the connecting plate from shaking.

Description

technical field [0001] The invention relates to the technical field of automobile production equipment, in particular to a clutch heat capacity testing device. Background technique [0002] The wet clutch mainly plays the role of starting, shifting, and stably transmitting torque during the running of the car. During the starting and shifting process, the clutch is always in a slippery state. When the road conditions are complex and the vehicle load is heavy, the temperature between the discs will rise rapidly due to long-term friction, and the clutch will be easily ablated. In order to study the boundary conditions of clutch starting and shifting conditions and reduce the risk of clutch ablation, it is necessary to test the clutch heat capacity. While the clutch is in working condition, all components are rotating at high speed. If a high-precision temperature sensor is arranged between the plates, the sensor must rotate together with the clutch hub. During the high-speed...

AI Technical Summary

Problems solved by technology

During high-speed rotation, the temperature sensor wire is easily broken and damaged, resulting in repeated testing process and waste of resources such as sensors and test benches

At present, the commonly used wireless inductive temperature test device is subject to large electromagnetic interference, the test is very unstable, and the measured data results are not reliable.

However, the centering accuracy of its connection with the output end of the wet clutch is poor, the transmission torque is unstable, and the housing of the input and output ends of this stable sensor does not rotate, so the sensor cannot be arranged at the input or output end of the wet clutch
