Abstract

The invention discloses an electric power measuring machine automatically centering automobile chassis, which comprises a machine frame, wherein the middle of the machine frame is fixedly provided with a supporting shell, the middle of the which is provided with a double-shaft motor, the two output shafts of the double-shaft motor are respectively provided with a rolling drum, each of the rolling drums is provided with a centering mechanism, the centering mechanisms of the two rolling drums are arranged in the manner of bilateral symmetry, and each centering mechanism comprises a screw rod arranged vertical to the rolling drums and rotationally connected to the machine frame, and lifting mechanisms symmetrically arranged on the front and rear sides of the rolling drums. The invention uses the automatic centering mechanisms so that the vehicle is quickly and correctly centered, greatly reduces the workload of testers, saves the preparation time of tests, saves lots of miniature parts compared with the prior centering mechanism, and has simple and practical structure. A bearing mechanism driven continuously is arranged between the end part of the double-shaft motor and the rolling drum corresponding to the bearing mechanism so as to enhance the correctness of the tests and prolong the service life of the power measuring machine.

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...
