Abstract

The invention discloses an electric vehicle brake inertia simulating testing table and method. The electric vehicle brake inertia simulating testing table comprises a motor, a speed reducer, axle shafts, a driving wheel, levers, loading bearing blocks, movable pulleys, idler wheels, a driving wheel, flywheels and speed reducing machines, wherein a driving and transmission system is composed of the speed reducer, the axle shafts, the motor and the driving wheels and is connected with the levers, the loading bearing blocks are fulcrums of the levers, the levers are connected with a rack through hinges, steel wire ropes penetrate through loading weights, the movable pulleys are connected to lever arms through pins, the idler wheels are driven by the driving wheels to have the road surface simulation effect on the idler wheels, and the flywheels are connected with the idler wheels through the speed reducing machines. Multiple testing results can be simulated through the electric vehicle brake inertia simulating testing table.

Description

[0001] technical field [0002] The invention belongs to the technical field of electric vehicles, and in particular relates to a simulation test bench and a test method for braking inertia of electric vehicles. Background technique [0003] Today's world is facing severe challenges of energy shortage and environmental pollution. Energy and environmental issues have become the most concerned issues of all countries in the world. In order to improve environmental pollution, reduce energy consumption, and achieve long-term economic development, countries have invested huge manpower and material resources in the research and development of new energy. To cope with the depletion of energy and the deterioration of the environment. [0004] As the government and society pay more and more attention to environmental pollution and energy issues, energy conservation and environmental protection have become one of the main goals of the development of the automobile industry. The devel...
