Problems solved by technology
But the disadvantage is that because the moment of inertia of the pure eddy current dynamometer itself is too small, it cannot simulate the inertia force of the gearbox output load in the vehicle test. If it is necessary to simulate the inertia force more realistically, it needs to be added on the test bench. Some combined flywheels to simulate the real inertia of the vehicle

The invention involves a car gearbox test table that can simulate road conditions, mainly consisting of the following parts: the input side torque speed sensor of the input side of the input terminal of the input of the measured transmission, the measured transmission, the measured transmission outputThe left torque speed sensor and right torque speed sensor on the left side, the left flywheel set and the right flywheel set, the left load measurement machine and the right load measurement machine, the left side measurement machine controller and the right side measurement machineController, driving motor controller and monitoring system.The present invention is mainly an innovative design conducted by the test table frame using the electrical vortex meter as a transmission output load that cannot complete the dynamic test of the road of the simulation vehicle.Its most significant feature is: this test table can simulate the entire vehicle inertial force in the dynamic test by entering the side of the Electrical Blottering Machine in the Electrical Blottering Machine.ability.
Description
technical field [0001] The invention belongs to a test device, in particular to a vehicle gearbox test stand. Background technique [0002] The existing vehicle gearbox test bench, when using the eddy current dynamometer as the output load of the gearbox, although the eddy current dynamometer has a certain dynamic working condition test capability, it cannot completely simulate the vehicle transmission under all working conditions. The inertial force of the box on the road. [0003] At present, most of the mainstream gearbox test benches use electric dynamometers as the output load of the gearbox. However, the cost of electric dynamometers is relatively high, and the power equipment needs to be modified accordingly, resulting in high overall costs. In response to the above problems, our company adopts a gearbox test bench, and uses an eddy current dynamometer as the output load of the gearbox. But the disadvantage is that because the moment of inertia of the pure eddy curr...
