Description

Technical Field

[0001] The invention relates to a test device for automatically balancing contact surface pressure, in particular to a test device for sliding contact which can automatically balance the force of the contact surface so that the contact surface can stably transmit current. Background Art

[0002] The pantograph slider is a device used in rail transit to transmit power (electric energy) to rail transit vehicles. It is necessary to ensure stable and reliable power transmission, and also to ensure the wear resistance of the contact surface. In actual use, the device is to install an M-shaped copper wire on the running track of the rail transit vehicle. The pantograph slider is installed on the vehicle and moves with the vehicle. The pantograph slider is pressed against the copper wire on the track through the force-adding device to achieve the transmission of electric energy. A large number of tests and verifications are required in the early stage of product development. In order to simulate the actual working conditions of the product, the copper wire is installed on the moving plate, and the product is pressed against the copper wire and slides back and forth for testing. However, the current similar friction and wear test device cannot automatically balance the pressing force between the friction pairs of the product and the copper wire. If the moving plate jumps and eccentric wear occurs, the contact pressure of the friction surface will be uneven, resulting in a reduction in the contact area or poor contact, which will cause discharge and electro-corrosion during the current transmission process, thereby causing a greater impact on the test data. Summary of the invention

[0003] The purpose of the present invention is to propose a test device for automatically balancing the contact surface pressure, which can automatically adjust according to the pressure changes on the contact surfaces between friction pairs to ensure reliable contact between the contact surfaces, thereby ensuring reliable and stable power transmission between the contact surfaces.
