New energy automobile full-road-condition road-test-free simulation teaching and detection table

Abstract

The invention discloses a new energy automobile full-road-condition road-test-free simulation teaching and detection table and belongs to the technical field of new energy automobile full-road-condition road-test-free simulation teaching and detection instruments. The new energy automobile full-road-condition road-test-free simulation teaching and detection table comprises an automobile without tires, a variable-frequency motor and a feedback control cabinet and is characterized in that a base plate is padded under an automotive chassis, a brake disc on the automobile is suspended from the ground; the free end of the brake disc is connected with one end of a telescopic drive shaft through a flange, and the other end of the telescopic drive shaft is connected with the variable-frequency motor through a coupler; a sensor is installed on the telescopic drive shaft and is connected with the feedback control cabinet through a lead, and the variable-frequency motor is connected with a standard power grid through a frequency converter and a feedback unit. The new energy automobile full-road-condition road-test-free simulation teaching and detection table can increase the driving experience of trainees to the full road conditions of the new energy automobile and decrease the repeated teaching work amount of a trainer on the premise that the safety of the trainees is ensured, converts kinetic energy of the automobile into the electric energy the same as the voltage of the standard power grid while simulating the full road conditions of the automobile, feeds the electric energy back to a national power grid and makes energy recyclable.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicle full road condition simulation teaching and testing instruments, in particular to a new energy vehicle full road condition free road test simulation teaching testing platform. Background technique [0002] New energy vehicles refer to all other energy vehicles except gasoline and diesel engines, including fuel cell vehicles, hybrid vehicles, hydrogen energy vehicles and solar vehicles. Its exhaust emissions are relatively low. According to incomplete statistics, there are more than 4 million liquefied petroleum gas vehicles and more than 1 million natural gas vehicles in the world. At present, the new energy vehicles on sale in the Chinese market are all hybrid vehicles and pure electric vehicles. [0003] The road test of new energy vehicles can effectively improve students' driving experience and intuitive understanding of new energy vehicles. However, there are students who have no...

Problems solved by technology

[0007] However, the chassis dynamometer can only generate resistance but not power, so it cannot fully simulate the power generated by the car when going downhill. The steering wheel makes it easy for the vehicle to slide off the roller; moreover, in order to generate resistance during the operation of the chassis dynamometer connected to the eddy current loader, the eddy will be energized to generate resistance, and at the same time a large amount of heat energy will be generated, and the heat energy are often wasted and cannot be used effectively
