Automatic Comprehensive Roller Test Bench Vehicle Speed Torque Horsepower Working Condition Simulation Tester

The structure of the test bench is mainly composed of a bracket, a large mobile base, a moving guide rail, a basic frame, a motor, a reduction wheel, a hub assembly, a pneumatic lifting device, a speed sensor, a displacement sensor, a frequency converter and other components.The drum test bench uses the electric inertia to simulate the kinetic energy of the vehicle on the road, and can withstand the load of the vehicle at the maximum acceleration and deceleration. Rotary drum warp good dynamic balance. It has the following functions:Dynamic driving brake force test: the car drives the drum. When the speed of the car reaches 80 km/h (the speed can be set by the user), brake until the car stops, and measure the dynamic driving braking force during the deceleration process.Astern test test (open or close as required).Acceleration performance (on or off as required)Automatic transmission testing and diagnostics, communication with the automotive ECU, according to test specifications (open or close as required).A safety drum protection device is installed at the rear of the rear drum group to prevent the vehicle from running out of the test stand during the test. In order to facilitate vehicle access to the test bench, a pneumatic lift is installed in the middle of each pair of rollers. Using electric inertia to simulate the equivalent kinetic energy of a vehicle on the road, it can withstand the load of the vehicle during maximum acceleration and deceleration. The drum has good dynamic balance. It has the following functions: Braking force inspection (including the function of the brake table) display result summary and braking force curve, vehicle offline ABS/ESC/EPB test, display result summary and process curve, upshift/reverse performance test, coasting dynamic braking performance test (optional test items), speedometer test, sound level test (integrated), electric vehicle energy recovery test, air conditioning temperature test (integrated), brake pedal force and manual operation force test (optional test items)
