Anti-sedimentation center plate structure for railway vehicles

Abstract

The invention discloses an anti-sedimentation center plate structure for railway vehicles, which comprises an upper center plate and a lower center plate, wherein the edge of the upper center plate is provided with a bulge I, the middle of the upper center plate is provided with a groove, the middle of the lower center plate is provided with a bulge II, the groove of the upper center plate is matched with the bulge II of the lower center plate, a center-plate abrading disc with a central hole is arranged between the groove of the upper center plate and the bulge II of the lower center plate, the middles of the upper center plate and the lower center plate are respectively provided with a central hole, the upper part of the central hole of the lower center plate is provided with a tapered hole, and the diameter of the tapered hole is greater than the diameter of the central hole of the upper center plate. The center plate structure disclosed by the invention is simple in structure and manufacturing process and low in cost; and water and sand can be prevented from entering the center plate structure and being sedimentated in the lower center plate, water from vehicle bodies can be drained, and the steering resistance moment of a vehicle is not affected, thereby solving the problem that sand and rainwater occurring in windy, sandy and rainy areas are sedimentated in the center plates of vehicles.

Description

technical field [0001] The invention relates to the technical field of railway vehicle machinery, in particular to a railway vehicle anti-silting center plate structure which is sand-proof, waterproof and free from silting water and sand. Background technique [0002] The center plate structure of the railway vehicle is composed of the upper center plate directly connected with the car body and the lower center plate connected with the bogie. When the car body and the bogie are assembled, the upper center plate and the lower center plate cooperate with each other to transfer the weight of the car body. Constrain the relative position of the bogie and the car body, allow the relative rotation of the bogie and the car body when passing the curve, and provide the function of turning resistance torque. The center plate structure of the prior art is that the upper center plate is protruding, and the lower center plate is provided with grooves. The defect of the structure of the l...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem of sand, water and rust-removing iron sand caused by the groove of the lower center disc in the prior art, which causes abnormal wear of the upper and lower center discs and the wear disc of the center disc, which affects the turning resistance torque of the vehicle and causes The problem of the decline in the running quality of the vehicle; provide an anti-silting core plate structure for railway vehicles; it has a simple structure and manufacturing process, low cost, and can not only prevent water and sand from entering and depositing in the lower core plate, but also can discharge water and sand from the car body. moisture, and does not affect the turning resistance torque of the vehicle
