Problems solved by technology
[0003] At present, the test method for new energy reducers mainly adopts the vehicle working condition test method. The test conditions are not only limited by the development progress of the vehicle, but also the repeatability and reliability of the test data are poor, and the test timeliness is poor.
Therefore, how to test and measure the impact durability of the reducer of the new energy vehicle under the condition of simulating the whole vehicle on the bench is expected to become a new way to solve the insufficient test of the whole vehicle. However, there are no relevant reports at home and abroad.

The invention discloses a new energy decelerator impact endurance test method comprising the following steps: a computer controls a driving motor to start, and an electromagnetic clutch controls a decelerator to rotate; the computer acquires input and output rotating speed and torque signals obtained by the rotating speed and torque sensor in real time through a data acquisition system, judges whether a set rotating speed is reached or not according to the acquired rotating speed, separates the electromagnetic clutch and stops working of the driving motor if the set rotating speed is reached, and then starts the brake for brake simulation; and the steps are repeated until specified test times are finished or the gear fails, and the test is ended. And the computer records and displays the acquired relevant rotating speed data and torque data in real time. According to the method, the test working conditions such as starting and braking of the speed reducer can be simulated, and the impact durability of the gear of the speed reducer can be accurately measured under the test working conditions, so that the impact durability test data under different working conditions can be quickly and accurately obtained with low cost.
Description
technical field [0001] The invention relates to the test and measurement of the performance of a reducer in a new energy vehicle transmission system. More specifically, the invention relates to a new energy reducer impact durability test method, which belongs to the technical field of vehicle testing. Background technique [0002] In the face of the rapid development of the automobile industry, the wave of electrification and intelligence, coupled with the national level's desire to reduce dependence on imported oil, and the increasing environmental pollution, the development of new energy vehicles is highly anticipated. The reducer is an important part of new energy vehicles. Compared with traditional fuel vehicles, the new energy reducer has the characteristics of high speed and medium torque. The reducer on the new energy vehicle operates through gears, and most of them only use one transmission ratio to achieve deceleration, so when the electric car starts or brakes, it ...
