Embodiment

[0031] Figure 1-3 As shown, a specific embodiment of the present invention is: a measurement test bench capable of simultaneously measuring the three-way stiffness of a railway vehicle bogie, including a vertical loading mechanism 1, a wheel axle longitudinal loading mechanism 2 of a wheel set, and a frame longitudinal positioning mechanism 3. The axle lateral loading mechanism of another wheel set 4, the frame lateral positioning mechanism 5, the support base of the rail wheel, and there are two types of support bases of the rail wheel, namely the longitudinal support base 6 and the lateral support base 7.

[0032] figure 1 , 2 , 4-6 show that the support base of the rail wheel corresponding to the longitudinal loading mechanism is the longitudinal support base 6, which is composed of two positioning cams with the same cross-sectional shape as the rail cross-sectional shape located in the longitudinal distribution of the rail wheel tread 14, two positioning cams 14 are fix...

Abstract

The invention discloses a measurement testing bench which can measure three-direction rigidity of bogies of railway vehicles at the same time. A longitudinal or transverse rail wheel supporting base has the structure that an upper supporting plate is connected with a lower longitudinal or transverse movable platform by a load sensor; the longitudinal or transverse movable platform is internally provided with a cylinder roller which can be longitudinally rolled or transversely rolled by a bearing; two cylinder rollers are respectively arranged on a longitudinal or transverse convex beam of the base. During the testing, the rolling movement of the base and the movable platform is realized by the rolling of the cylinder rollers, with small friction force and smart movement. Parameters of vertical rigidity, longitudinal rigidity, transverse rigidity and geometrical structure of the bogies of the railway vehicles can be tested on the measurement testing bench which has the advantages of exact measurement value, high precision, simple structure, convenient operation and easy maintenance.

Description

technical field [0001] The invention relates to a test device for measuring parameters of a railway vehicle bogie, in particular to a detection device for measuring parameters such as various stiffnesses and structural dimensions of a railway vehicle bogie. Background technique [0002] The railway vehicle bogie is mainly composed of wheelset, frame, primary and secondary suspension devices, on which the vehicle body is carried, and it is the running mechanism of the vehicle. Its main parameters include wheel weight, self-weight, wheel set inner distance, fixed wheelbase, wheel axle parallelism, vertical stiffness, longitudinal stiffness, transverse stiffness, etc. The size and matching of each parameter determine the dynamics of the vehicle bogie Performance is good or bad, in the actual line operation, it directly affects the running speed, running stability, comfort and safety reliability of the train. Therefore, it is very necessary to accurately measure and study the m...
