Embodiment Construction

[0013] Referring to Fig. 1 and Fig. 2, a railway freight car bogie swing device is characterized in that the swing device is designed to connect the bogie bolster 1 with the side frame 2 and adopts a ball joint structure, and the swing device consists of a swing seat 3. The arc-shaped wear-resistant bushing 4 and the positioning hemisphere 5 are composed; there is a concave spherical surface on the swing seat 3, and the arc-shaped wear-resistant bush 4 is press-fitted on the concave spherical surface of the swing seat 1. In the arc-shaped wear-resistant bushing 4, the concave spherical surface of the arc-shaped wear-resistant bush 4 cooperates with the positioning hemisphere 5; the swing seat 1 is connected to the bolster 1 through the interference fit between the column and the hole, and the positioning hemisphere 5 is set On side frame 2.

[0014] The swing seat in the swing device is connected to the bolster through the interference fit between the column and the hole, and ...

Abstract

The invention provides a swing device which connects a truck bogie bolster with a side frame through a spherical hinge. A swing seat is connected with the bolster through the interference fit between a column and a hole; the concave sphere of the swing seat and the positioning half ball of the side frame are matched to play a role of load transmission. The swing seat is internally provided with a wearable liner. When the side frame swings, the bolster rotates corresponding to the side frame and provides friction moment. The swing device can effectively release the transverse motion of the bolster, meanwhile, the friction moment of the bolster can be changed correspondingly along with the changes of the loads of empty and heavy vehicles; the invention is equivalent to a transverse variable friction damper and effectively meets the requirement that different transverse damps are needed by the empty vehicle and heavy vehicle ; the invention leads the bogie to have the characteristic of variable rigidity, thus improving the critical speed and transverse kinetic performance of the vehicle. The invention improves the kinetic performance of vehicles, enhances the operation quality of vehicles, reduces the maintenance cost of vehicles, meets the requirement of heavy load and fast truck of the rail development, and has better social benefits and economic benefits.

Description

technical field [0001] The invention relates to a railway freight car bogie swing device. Background technique [0002] At present, most railway freight car bogies are structures in which side frames and bolsters are directly connected by springs, and there are generally relatively few bogies without special swing devices. When the side frames and bolsters are directly connected by springs, the lateral displacement of the bogie structure is relatively small, and it is difficult to guarantee the performance during operation at high speeds. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned defects, and provides a railway freight car bogie swing device that connects the bogie bolster and the side frame through a spherical joint. [0004] The technical solution of the present invention is: a railway freight car bogie swing device, which is characterized in that the swing device is designed to connect the bogie bolster wi...
