Abstract
The utility model discloses a simulation test bench for an anti-lock braking system of a brake, and the test bench comprises a supporting frame; a driving shaft which is rotatingly disposed on the supporting frame; a driven shaft which is rotatingly disposed on the supporting frame; a flywheel group which is fixedly disposed at the central part of the driving shaft; a driving device which is in driving connection with the driving shaft; and a test device which is disposed on the driving and driven shafts. The driving shaft is parallel to the driven shaft, and is connected with the driven shaft through a transmission device. The flywheel group can drive the driving shaft to rotate, and the driving device can drive the driving shaft to rotate, thereby driving the flywheel group to rotate. The simulation test bench employs one flywheel group to simulate the translational inertia of a vehicle body, and, compared with a mode of employing four flywheel groups to simulate the translational inertia of the vehicle body, reduces the energy consumption in a transfer process. Moreover, there is no need of considering the errors caused by the machining and installation of the four flywheel groups, so employing one flywheel group to simulate the translational inertia is more reasonable and accurate than employing four flywheel groups to simulate the translational inertia.
