Abstract

The invention discloses a rotary transverse positioning device for a bogie rotational resistance moment test table. The device consists of a transverse positioning mechanism assembly (A) and a rotary central positioning mechanism assembly (B) and provides rotary central and transverse positioning for the test table. A positioning square pillar (d) in the rotary central positioning mechanism assembly (B) is fixed in a lower cast iron platform to provide vertical and transverse constraint force for the test table. A central shaft slider mechanism assembly (c) and the transverse positioning mechanism assembly (A) in the test table are matched and linked to provide a rotary center for the test table. A middle open type slider device of the central shaft slider mechanism assembly (c) is matched with a slider guide rail to provide transverse constraint and longitudinal degrees of freedom for the test table, and cut-off of a rotary shaft caused by the fact that two longitudinal actuators of the test table push or pull in the same direction due to control imbalance of a electrohydraulic servo system is prevented, so that test of rotational resistance moment of the test table can be guaranteed.

Description

technical field [0001] The invention relates to testing equipment in the field of rail vehicles, in particular to a rotary shaft and a lateral positioning device for a bogie rotary resistance moment test bench. Background technique [0002] The bogie is a key component of a rail vehicle, and its performance parameters directly affect the running quality of the vehicle. Slewing resistance torque is an important dynamic parameter of the bogie, which directly affects the dynamic performance of the bogie and is related to the running quality of the train. If the turning torque is too large, the train will derail due to the large gauge tension when passing through the curved track; if the turning moment is too small, the vehicle will shake its head and snake-like movement during operation, which will affect the stability of the vehicle running. [0003] At present, the test of the turning resistance torque of the bogie is mainly carried out on the bogie parameter test platform. ...
