Power transmission device of test bed of high speed train suspension type bogie traction drive system

Abstract

The invention discloses a power transmission device of a test bed of a high speed train suspension type bogie traction drive system, and the device is composed of a 1# roller pair and gear box assembly (1), a coupler (2) and a 2# roller pair and gear box assembly (3). The 1# roller pair and gear box assembly (1) and the 2# roller pair and gear box assembly (3) are respectively mounted at the front end and back end of a basic platform (22), wherein the wheel base between a 1# roller shaft (7) in the 1# roller pair and gear box assembly (1), and a 2# roller shaft in the 2# roller pair and gear box assembly (3) is equal to that of the bogie to be tested. A 1# coupling flange (14) in the 1# roller pair and gear box assembly (1) is opposite to a 2# coupling flange in the 2# roller pair and gear box assembly (3); one end of the coupler (2) is fixedly connected with the 1# coupling flange (14) in the 1# roller pair and gear box assembly (1), and the other end of the coupler (2) is fixedly connected with the 2# coupling flange in the 2# roller pair and gear box assembly (3).

Description

technical field [0001] The invention relates to a test device for railway high-speed trains, more specifically, the invention relates to a power transmission device for a high-speed train frame-suspended bogie traction transmission system test bench under the working conditions of simulating high-speed train running. Background technique [0002] On April 18, 2007, my country successfully implemented the sixth national railway speed-up map adjustment. Harmony CRH series EMUs appeared on Chinese railways for the first time, realizing 250Km / h high-speed operation on existing lines, thus unveiling It marked the prelude to the high-speed development of my country's railways. At present, the maximum speed of the EMUs in operation has reached 350km / h, but with the increase of the speed, the operating conditions of the components of the high-speed train bogie traction drive system have become worse, and the safety and reliability of key components in operation The problem is becomi...
