Problems solved by technology
[0003] The inventor finds that there are at least the following problems in the prior art: the price of the permanent magnet synchronous motor with low inertia is very expensive
[0004] Since both the ABS test and the TCS test require the dynamometer to switch the speed rapidly to follow, and even if the permanent magnet synchronous motor with low inertia is used to simulate the drastic speed change, since the permanent magnet synchronous motor still has inertia, it still cannot completely Simulate the test scenarios required by the vehicle under test
This method can only be used to verify the function of the vehicle, but the accuracy of the vehicle optimization calibration test is not enough

The invention discloses a friction simulation device, comprising: a first transmission shaft, a first transmission wheel, a second transmission wheel, a second transmission shaft, a plurality of friction plates and a driving mechanism, the first transmission wheel and the first transmission shaft Coaxial fixed connection; the second transmission wheel is located on the radially outer side of the first transmission wheel, and coaxially arranged with the first transmission wheel; the second transmission shaft is coaxially fixedly connected with the second transmission wheel; a plurality of friction plates are all along the first The axial direction of a transmission wheel is sequentially arranged between the first transmission wheel and the second transmission wheel. Part of the friction plates are engaged with the first transmission wheel in the circumferential direction and movably connected in the axial direction, and some friction plates are connected with the second transmission wheel. The two transmission wheels are clamped in the circumferential direction and movably connected in the axial direction; the driving mechanism is operable to press or loosen each friction plate along the axial direction of the first transmission shaft. The frictional force applied by the ground to the wheels of the vehicle can be simulated by the frictional force simulation device.
Description
technical field [0001] The embodiments of the present invention relate to the field of automobile test and maintenance equipment, and in particular to a friction simulation device. Background technique [0002] After the production of existing vehicles is completed, the performance of the vehicle needs to be tested. When testing the vehicle, a device such as a dynamometer needs to be used to provide a load for the vehicle under test. When the vehicle is tested for ABS (antilock brake system) and TCS (Traction Control System), the speed change rate (angular acceleration) of the wheel changes greatly, so a permanent magnet synchronous motor with low inertia is required (that is, the dynamometer mentioned above) to provide load to the vehicle, and the permanent magnet synchronous motor is used to simulate the severe speed change rate of the wheel, so as to perform ABS test and TCS test. [0003] The inventors have found at least the following problems in the prior art: the low...
