A double-roller flexible chassis test device

Abstract

The invention relates to a double-roller type flexible chassis testing device, which belongs to the field of vehicle engineering. In order to overcome the shortcomings of an existing chassis testing device, the double-roller type flexible chassis testing device is provided with a revolving platform and a differential mechanism under each of four driving wheels of a test chassis, wherein a revolving center of each revolving platform is concentric with a chassis bias steering shaft, a double-roller rotating mechanism is arranged on a platform for driving the corresponding differential mechanism, and the driving wheels of the test chassis are arranged on the double-roller rotating mechanisms, thereby completing performance parameter test of the test chassis. The double-roller type flexible chassis testing device disclosed by the invention has the advantages of being firm in structure and high in bearing capacity, simulating a steering mechanism of the test chassis in the road driving process more accurately through following the steering of the chassis steering shafts by the double-roller differential rotating mechanisms, being simple in structure, and being convenient in simulation demonstration and control parameter test.

Description

technical field [0001] The invention relates to a four-wheel independent drive independent steering chassis test device, belonging to the field of vehicle engineering, in particular to a four-wheel independent drive independent steering flexible chassis test equipment. Background technique [0002] With the continuous development of society, the number of vehicles is increasing, and the roads are somewhat narrow, and the space required for parking vehicles is becoming more and more tense. So in the process of parking or U-turn will cause vehicle jam phenomenon, its main cause is due to the incomplete function of existing vehicle steering gear. [0003] Patent 200610104895.9 (publication number CN1948040) discloses a vehicle drive device, which improves the existing vehicle drive structure so that each wheel can be driven and turned. [0004] Patent 200910021065.3 (publication number CN101480968) discloses an electric vehicle drive chassis, which is composed of hub motors, b...

AI Technical Summary

Problems solved by technology

The traditional test is carried out in the form of linear motion, but the steering shaft of the four-wheel independent drive independent steering chassis performs circular motion, and the linear motion test device is not only complicated in structure, but also has many inconveniences

The turntable-type independent drive and independent steering chassis test bench disclosed in the above patent can change the linear motion of the flexible chassis into a circular motion, but due to the structural limitations of the turntable test bench, it is impossible to closely combine the chassis and the test bench. As a result, many performance parameters of the chassis cannot be verified or obtained
