Abstract
The invention discloses a suspension type electric dynamometer for an automotive chassis, which comprises a frame. A support shell is fixedly arranged in the middle of the frame. A biaxial motor is arranged in the middle of the support shell. A roller is arranged on two output shafts of the biaxial motor respectively. A continuously driven bearing mechanism is arranged between two ends of the shell of the biaxial motor and the corresponding rollers respectively. The continuously driven bearing mechanisms at two ends of the shell of the biaxial motor are symmetrical and has the same rotation speed and opposite rotation directions. Due to the arrangement of the continuously driven bearing mechanisms between the end part of the biaxial motor and the corresponding rollers, the test accuracy is enhanced and the service life of the dynamometer is prolonged. The drive motor is the high-torque low rotation speed biaxial motor, and is assembled at the middle position of the dynamometer. Therefore, the structure is compact and reasonable, the installation is quick and convenient, and the occupancy area of a base pit is reduced.
Description
technical field [0001] The invention relates to a vehicle performance testing device, in particular to a chassis dynamometer for indoor bench tests of small and medium-sized vehicles. Background technique [0002] The automobile chassis dynamometer is an important indoor bench test equipment. The chassis dynamometer can not only test the dynamic performance of the automobile, but also measure the emission indicators and fuel consumption of multiple working conditions. The function of the automobile chassis dynamometer is to simulate various working conditions of the vehicle by replacing the road surface with the surface of the drum through the control of the load simulation and loading device. It has the advantage of not being affected by external conditions. It can be detected quickly without disintegration of the car, and accurately reflect the technical status and performance of each mechanism, system, and component of the car. The automobile chassis dynamometer can fin...
