Abstract

The invention discloses a chassis dynamometer test bench driven by a permanent magnet synchronous motor. The chassis dynamometer test bench is characterized by comprising at least two dynamometers, abase, a slide rail arranged on the base, a pushing mechanism, a lifting mechanism and at least one mounting base slidably mounted the slide rail. The at least two dynamometers operate independently, are driven by the permanent magnet synchronous motor and are controlled by an all-electric inertia system. Every two dynamometers are installed on the same mounting base. The pushing mechanism is configured to push the mounting base along the slide rail. The lifting mechanism is configured to adjust the heights of the dynamometers to the ground. The chassis dynamometer test bench is capable of separately testing the wheels of a vehicle, and is simple in structure and adjustable in wheelbase.

Description

technical field [0001] The invention relates to the technical field of automobile testing equipment, in particular to a chassis dynamometer test bench driven by a permanent magnet synchronous motor. Background technique [0002] The chassis dynamometer is a kind of indoor bench test equipment used to test the performance of automobile power, multi-condition emission indicators, fuel indicators, etc. The automobile chassis dynamometer simulates the road surface through the roller, calculates the road simulation equation, and uses the loading device Carry out simulation to realize accurate simulation of various working conditions of the car.
