Abstract

The invention discloses a centrally-mounted motorcar chassis electricity dynamometer which comprises a lifting mechanism. The lifting mechanism comprises a screw connected with a screw rod, and the screw is connected with a rocker by a link I; the upper end of the rocker is fixedly connected with a lateral horizontal shaft, and the lateral horizontal shaft can be installed on a stander in a rotatable mode and is fixedly connected with a side link which extends toward the middle lower part of the dynamometer; the lower end of the side link is articulated with one end of a link II, and the other end of the link II is articulated with a top plate; both sides of the top plate are respectively provided with a convex block, and the convex block is matched with a rail of the stander; the rail arches upwards to form an arch for guiding the lifting of the top plate; and the free end of the top plate is provided with a supporting roller. The invention can center motorcars accurately and quickly by adopting an automatic centering mechanism, thereby reducing the workload of testing personnel, saving test preparation time and omitting lots of small-sized parts and components, so that the structure is simple and practical.

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...
