Embodiment Construction

[0026] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0027] Such as figure 1 As shown, the preferred embodiment of the present invention provides a test system, which can be used to test powertrain devices such as gearboxes, differentials, clutches, or other devices whose performance is to be tested, so as to test relevant data. In order to realize the purpose of the present invention, this test system comprises drive system 1, transmission system, load system 8 and test piece 14, and wherein, transmission system comprises the carbon fiber drive shaft 3 that is connected between drive system 1 and test piece 14, and connects Carbon fiber load shaft 6 between load system 8 and test piece 14 . In this way, because...

Abstract

The invention discloses a testing system, comprising a driving system (1), a transmission system, a load system (8) and a testing member (14). The transmission system comprises a carbon fiber driving shaft (3) which is in transmission connection between the driving system (1) and the testing member (14), and a carbon fiber load shaft (6) which is in transmission connection between the load system (8) and the testing member (14). The adopted flexible carbon fiber shaft is light in weight and small in rotation inertia and is good in torsional vibration characteristic and has a good vibration absorption function particularly when the shaft is long. The invention can reduce the effect of the transmission shaft on the testing member (14), can accurately measure the characteristics of the testing member (14), and particularly is applicable to the power assembly device of the gearbox.

Description

technical field [0001] The present invention relates to the field of automobile industry, in particular to a test system, especially a test system for powertrain devices such as gearboxes. Background technique [0002] As the core components of automobiles, powertrain devices such as automobile gearboxes directly affect the quality of the entire vehicle. The test system used to test its performance detects its performance indicators in various aspects by simulating its state under different working conditions. The drive shaft is used to connect the test piece and other structures in the system. Its reliability is of paramount importance. It can transmit torque smoothly without causing additional impact on the system itself. In the prior art means, the transmission shaft is a rigid shaft, the moment of inertia is relatively large, and the vibration and noise generated are also relatively large, especially when the transmission shaft is long, the influence is more obvious. C...
