Abstract

A steering rack performance test bed comprises a rail device capable of bearing a test vehicle and a traction device located at the front side of the rail device, the traction device comprises a fixing base fixedly arranged on the foundation and a traction rod capable of connecting and drawing the test vehicle, the traction rod is connected with the fixing base, and the rail device comprises a plurality of rail wheel units which are arranged from front to back. The steering rack performance test bed enables the test vehicle to operate on the rail device, can realize the railway vehicle rolling tests comprising a hunting instability critical speed test, a bearing running temperature rise test, etc., and is small in occupation space. The test vehicle drives in situ to test without needing to move actually, so that the safety is strong, the driving state of the vehicle is also convenient to observe during the test process, and the detection sensors also can detect the experiment data more accurately. By the inertia wheel devices, the steering rack performance test bed also can realize the braking performance tests comprising the emergency braking, the braking distance test of the service braking, the temperature rise tests of the brake-shoes and the wheels during a braking process, etc.

Description

technical field [0001] The invention relates to a rail vehicle test equipment, in particular, it is a rail vehicle bogie test bench which can complete the rolling performance test and braking performance test of the railway vehicle and is compatible with different gauges, wheelbases and fixed distances. Background technique [0002] A railway vehicle is mainly composed of a car body and two bogies, and the car body and bogies are connected by a secondary suspension system. The bogie performance test generally takes a railway vehicle as the test unit, and the test content mainly includes rolling performance test, braking performance test, etc. The rolling performance test is mainly to test the critical speed of the snaking instability of the railway vehicle and the temperature rise test of the bearing running-in; the braking performance test is mainly to test the braking distance of emergency braking and common braking. Wheel temperature rise test, etc. [0003] Existing ra...
