Embodiment Construction

[0040] The present invention provides an embodiment of a rotating system stall torque measuring device, which includes: a driving mechanism, a torque transmission mechanism, a limit mechanism and a torque measuring mechanism; the driving mechanism drives the measured rotating system to rotate to a designated position through the torque transmission mechanism, and reaches After the specified position, the limit mechanism is the limit drive mechanism. After reaching the specified position, it outputs a variety of different current values ​​in the preset period until the rated current value drives the measured rotating system to rotate, and the measured rotating system transmits the locked-rotor torque through the torque transmission mechanism. to the torque measuring mechanism. For example, output various current values ​​from small to large to rated current value to drive the rotating system to be measured to rotate.

Abstract

The invention discloses a rotating system stalling torque measuring device, comprising a driving mechanism, a torque transfer mechanism, a limiting mechanism and a torque measuring mechanism, whereinthe driving mechanism drives a measured rotating system to rotate to a specified location through the torque transfer mechanism; after the specified location is reached, the limiting mechanism limitsthe driving mechanism; after the specified location is reached, a plurality of different current values are output within a preset time period until the rated current value is output to drive the measured rotating system to rotate; and the measured rotating system transmits a stalling torque to the torque measuring mechanism through the torque transfer mechanism. The invention also provides a rotating system stalling torque measuring method. According to the measuring device and the measuring method disclosed by the invention, the problem of inaccurate measurement of the stalling torque of therotating system caused by the torque overshoot can be avoided, the accuracy of measuring the stalling torque of the rotating system can be improved, and the product stability of the rotating system can be further improved.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a measuring device for locked-rotor torque of a rotating system in the field of automobiles. The invention also relates to a method for measuring the locked-rotor torque of a rotating system used in the automotive field. Background technique [0002] Rotary systems are widely used in the automotive field, such as: motors, gearboxes, engines, etc. For rotating systems / equipment, the stall torque is a key indicator, and 100% detection is often required in product verification. Taking the general-purpose actuator (GPA) as an example, the general-purpose actuator assembled on the turbocharger is used to control the wastegate valve switch of the turbocharger. Its function is to maintain a constant air pressure in the turbocharger, and the excess exhaust gas flow will pass through A wastegate controlled by a common actuator adjusts the pressure relief valve so that these flows do not pass ...
