Electric vehicle vibration integrated test platform

Abstract

The invention discloses an electric vehicle vibration integrated test platform which comprises a support frame (1), a front wheel support (2), a rear wheel support (3), and an electronic control device (4). The front wheel support is equipped with a front roller (21) driven by a front roller drive (22) and a front axle locating mechanism (23). The rear wheel support is equipped with two sets of rear rollers (31) driven by rear roller drives (32) and rear axle locating mechanisms (33), which are arranged in bilateral symmetry. The front roller drive and the rear roller drives are connected with the corresponding rollers through torque sensors. The controller of the electronic control device is electrically connected with a front roller drive motor, a rear roller drive motor and the torque sensors. The electric vehicle vibration integrated test platform is easy to operate. Off-site road test conditions can be simulated indoors. Test items can be completed under the premise of ensuring automatic and accurate test data acquisition. The electric vehicle vibration integrated test platform is especially suitable for operation test of electric tricycles or electric four-wheelers.

Description

technical field [0001] The invention relates to a vehicle detection platform, in particular to a vehicle vibration comprehensive test platform for electric tricycles or electric four-wheel vehicles, and belongs to the technical field of electric vehicle detection technology. Background technique [0002] Electric vehicles are electric-driven vehicles. Generally speaking, electric vehicles use batteries as energy sources. The electric energy is converted into mechanical energy through controllers, motors and other components, and the speed is changed by controlling the current. Electric vehicles can be classified according to their usage. For electric cars, electric tricycles and electric bicycles. [0003] For electric tricycles or electric four-wheelers, in order to ensure product quality and verify the performance of new products, electric vehicle manufacturers must conduct vehicle performance tests on electric vehicle products according to national standards or industry s...

AI Technical Summary

Problems solved by technology

[0003] For electric tricycles or electric four-wheelers, in order to ensure product quality and verify the performance of new products, electric vehicle manufacturers must conduct vehicle performance tests on electric vehicle products according to national standards or industry standards. In the case of simulation testing of electric vehicle road conditions, the road test verification is usually carried out at an outdoor test site. Not only does it need to arrange test test personnel and configure a large enough test site, but also the labor intensity of the test test personnel during the test run is relatively high. It is time-consuming and labor-intensive. At the same time, the detection instruments equipped for outdoor test drive testing are usually relatively simple, so the content of the test items is relatively small, and the data collected by manual operation is not completely accurate, so that it is impossible to accurately control the operation status of the electric vehicle during the test process, resulting in electric vehicles. The performance of the whole vehicle cannot be fully verified, and the faults or defects cannot be discovered in time, resulting in unstable product quality, and even inconvenience to users after the product leaves the factory. threaten
