Abstract
Description
Technical Field
[0001] The utility model specifically relates to the technical field of start-stop durability tests, and particularly relates to a start-stop durability test device for an automotive powertrain. Background Art
[0002] The powertrain, with the English name Powertrain or Powerplant, refers to a series of component assemblies on a vehicle that generate power and transmit the power to the road surface. Broadly speaking, it includes the engine, transmission, drive shaft, differential, clutch, etc. However, usually, the powertrain generally only refers to the engine, transmission, and the remaining parts integrated into the transmission, such as the clutch / front differential, etc.
[0003] After long-term use, the engine will experience jitter and noise. Especially during long-term testing of the start-stop function, it can further reduce the engine's lifespan. Therefore, when detecting the usage of the engine, it can be judged through jitter and abnormal noise. For this reason, we provide a start-stop durability test device for an automotive powertrain. The engine is clamped and fixed by two sliding clamping seats. Since the support plate is fixed to the frame by springs, the support plate will vibrate along with the engine, and noise detection is carried out by a noise monitor on one side to judge the usage of the engine, thus effectively compensating for the above problems.

[0023] By adopting the above technical solution, the engine is fixed on the support plate 4. Since the support plate 4 is connected with the frame 1 through the springs 3, the support plate 4 can conduct vibration, which is convenient for the vibration monitor 10 to detect the jitter generated by the engine. The noise monitor 8 above can detect the abnormal noise generated by the engine, and the spring mounting seat 2 plays a role of supporting and connecting.

[0025] Furthermore, a bi-directional lead screw 7 is connected with the pedestal bearing of the guide rail 5 in a matching manner, and the bi-directional lead screw 7 is connected with the two sliding clamping seats 6 through a bi-directional thread.
[0026] By adopting the above technical solution, since the sliding clamping seats 6 are slidably connected to the guide rail 5, and under the action of the two sliding clamping seats 6 being connected to the bi-directional lead screw 7 through threads, the two sliding clamping seats 6 move towards each other, so as to clamp different engines.
