A Test Bench for Power Train of Electric Hybrid Vehicle

摘要

A new type test bench was developed for power train used in electric hybrid vehicle. This bench was mainly composed of inertial flywheels, brake, clutch, dynameters, and controller. When testing the power train, the engine, power train, inertial flywheels, brake, clutch and dynameters are connected in series. One end of inertial flywheels is connected with output end of power train; the other end is connected with a clutch. Between the inertial flywheels and clutch, there is a brake for braking of flywheels. The clutch is for connection and disconnection of inertial flywheels and dynameters. This new test bench can perform different power modes with corresponding operation modes set in the main controller.
