Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0032] Such as Figure 1 to Figure 9 As shown, the pulling and cushioning device of the all-aluminum rail vehicle of the present invention comprises a corbel 1, a pulling beam 2, a coupler mounting seat 3 and two buffer beams 4, and the rear end of the corbel 1 passes through the drawing beam 2 and the coupler mounting seat. The front end of 3 is fixedly connected by welding, and the buffer beam 4 is symmetrically fixedly connected on both sides of the rear end surface of the coupler mounting seat 3 .

[0033] The corbel 1 includes two corbel small beams 1-1, corbel upper cover 1-2, corbel lower cover 1-4, six reinforcing vertical plates 1-5 and two torsion bar mounting seats 1-3, two corbel small beams 1-1 are arranged in parallel along the y-axis direction of the vehicle body to form a corbel frame, the thickness of the corbel upper cover 1-2 is 10 mm, and...

Abstract

The invention provides a traction sleeper buffer device of an all-aluminum railway vehicle and belongs to the field of traction sleeper buffer devices for railway vehicles. The traction sleeper bufferdevice comprises a sleeper beam, a traction beam, a drag gear installation seat and two buffer beams. A lower traction beam cover board and lower buffer beam cover boards of the traction sleeper buffer device are all made of an EN AW 5083 type aluminum plate material which is low in density, low in weight and good in bending performance, the drag gear installation seat is made from EN AW 6005A aluminum plates high in yield stress, other straight plate structures are all made of an EN AW 6082 type aluminum plate material high in yield stress, so that the overall selected materials of the traction sleeper buffer device meet the strength standard, and the welding and manufacturing processing property of the traction sleeper buffer device is the best. All lightening holes can be used as auxiliary holes at the same time in the inner cavity welding operation process, and therefore the accessibility and welding quality of an inner cavity welding joint are improved.

Description

technical field [0001] The invention belongs to the field of a pillow cushioning device for a subway vehicle, in particular to a pillow cushioning device for an all-aluminum material rail vehicle. Background technique [0002] Metro vehicles have the characteristics of safety and comfort, high speed and environmental protection, large transport capacity and low energy consumption, and have become an important part of urban public transportation. However, as the speed of the train increases, the strength requirements for the car body structure also increase. Although the old car body structures such as carbon steel and stainless steel meet the requirements for the strength of the car body structure, the weight index of the car body is limited by the material. Constraints, unable to meet lightweight requirements, resulting in high power consumption and high operating costs. In order to further reduce the weight of the car body, reduce energy consumption and operating costs on...
