Description

technical field

[0001] The invention relates to a test device for the performance of auxiliary equipment on a vehicle, in particular to a four-cylinder drive type vehicle electrical equipment reliability test bench, which belongs to the field of vehicle test in mechanical engineering. Background technique

[0002] Heavy-duty trucks used to transport bulk goods in factories, mines, construction and water conservancy sites often cause reliability failures and early damage to vehicle electrical equipment due to their harsh road driving conditions. For this, the national standard for automobile road test methods proposes to conduct automobile reliability and durability tests. permanent test or indoor simulation test, to provide quality assurance and control means for the vehicle electrical system, including instrument panel, combination switch, junction box, wiring harness, lamp, motor and other electrical equipment assemblies, which are suitable for road transportation condition...
