Air spring snow cover for rail vehicles

Abstract

An air spring snow cover for rail vehicles relates to the technical field of rail vehicle air spring protective devices, and includes a left semicircular cover and a right semicircular cover, which are assembled into a circular cover structure. The snow cover of the present invention can prevent the accumulation of ice and snow when the vehicle is traveling in snowy weather. The ice and snow accumulated in the local narrow cavity of the air spring will greatly affect the performance of the air spring. At the same time, it can effectively prevent foreign objects from hitting and damaging the rubber capsule of the air spring and the adhesion of dirt. The snow cover can be displaced together with the air spring when the rail vehicle is traveling, ensuring that the air spring is not exposed, and will not frequently wear with the air spring to damage the surface of the air spring capsule; in non-snowy weather, the snow cover can play a role in dust and dirt prevention.

Description

Technical Field

[0001] The invention relates to the technical field of rail vehicle air spring protection devices, and in particular to an air spring snow cover for rail vehicles. Background Art

[0002] like Figure 1 and Figure 2 As shown, the air spring 3 is a closed airbag structure as a whole, with a central shaft 3-1 connected to the vehicle body frame at the top and the bogie at the bottom, and an air hole 3-2 for inflation and exhaust is provided at the bottom of the air spring 3.

[0003] There is no protective device on the outside of the rail vehicle air spring. When the rail vehicle is running in severe ice and snow weather, a large amount of ice and snow will be adsorbed in the semi-open narrow cavity on the upper or lower part of the air spring. Ice will form due to the temperature difference, which will affect the performance of the air spring, making the stiffness characteristics and displacement ability of the air spring unable to meet the needs of vehicle operation. In serious cases, it may directly affect driving safety. At the same time, the setting of the protective cover will effectively prevent foreign objects from damaging the air spring, reduce the failure rate of external damage to the air spring, and to a certain extent reduce the vehicle operation and maintenance costs, including spare parts costs and labor replacement costs.

[0004] In addition, when ice and snow adhere to the surface of the air spring, manual cleaning is adopted, and each cleaning requires the use of chemical cleaning agents for decontamination and cleaning, which is time-consuming and labor-intensive. Summary of the invention

[0005] In order to ensure the performance of air springs under conditions of ice and snow accumulation, solve the additional maintenance costs caused by damage caused by foreign objects, and reduce the labor costs of cleaning, decontamination, maintenance and replacement, the present invention provides an air spring snow cover for rail vehicles.

[0006] The technical solution adopted by the present invention to solve the technical problem is as follows:

[0007] An air spring snow cover for a rail vehicle, comprising a left semicircular cover and a right semicircular cover, wherein the left semicircular cover and the right semicircular cover are assembled into a circular cover structure;

[0008] The left upper cover plate of the left semicircular cover is a semicircular plate, and a left upper semicircular hole is provided at the center of the left upper cover plate. A left groove is provided on one side of the left upper cover plate along the diameter direction, and a left convex plate is provided on the other side; the left lower cover plate of the left semicircular cover is a semicircular plate, and a left lower semicircular hole is provided at the center of the left lower cover plate; the left side wall of the left semicircular cover is a semicircular arc plate, and left connecting plates are provided at two ends of the semicircular arc plate on the left side wall;

[0009] The right upper cover plate of the right semicircular cover is a semicircular plate, and the right upper cover plate is provided with a right upper semicircular hole at the center position thereof, which is assembled with the left upper semicircular hole to form a circular hole. The right upper cover plate is provided with a right groove sealed and overlapped with the left convex plate on one side along the diameter direction thereof, and a right convex plate sealed and overlapped with the left groove on the other side; the right lower cover plate of the right semicircular cover is a semicircular plate, and the right lower cover plate is provided with a right lower semicircular hole at the center position thereof, which is assembled with the left lower semicircular hole to form a circular hole; the right side wall of the right semicircular cover is a semicircular arc plate, and the right side wall is provided with a right connecting plate buckled with the left connecting plate at each of the two ends of the semicircular arc plate;

[0010] The inner dimensions of the circular cover structure are larger than the outer dimensions of the air spring, the diameter of the circular hole formed by the upper left semicircular hole and the upper right semicircular hole is larger than the axial diameter of the central axis of the air spring, and the diameter of the circular hole formed by the lower left semicircular hole and the lower right semicircular hole is larger than 2R, R=r+d, r is the radius of the air hole of the air spring, and d is the distance between the axis center of the central axis and the center of the air hole.

[0011] The middle parts of the left side wall and the right side wall are respectively provided with three layers of annular fold structures for compensating for the displacement between the car body and the bogie during the operation of the vehicle.

[0012] The left semicircular cover and the right semicircular cover are both integrally formed structures.

[0013] The transverse inner dimension of the circular cover structure is 30 mm larger than the transverse outer dimension of the air spring.

[0014] The left semicircular cover and the right semicircular cover are both made of low-temperature-resistant and corrosion-resistant rubber material.

[0015] The beneficial effects of the present invention are as follows: the snow cover can prevent the accumulation of ice and snow when the vehicle is traveling in snowy weather. The ice and snow accumulated in the local narrow cavity of the air spring will greatly affect the performance of the air spring. At the same time, it can effectively prevent foreign objects from hitting and damaging the rubber capsule of the air spring and the adhesion of dirt. The snow cover can be displaced together with the air spring when the rail vehicle is traveling, ensuring that the air spring is not exposed and will not frequently wear and tear with the air spring to damage the surface of the air spring capsule; in non-ice and snowy weather, the snow cover can play a role in dust and dirt prevention. There is a 30mm gap between the snow cover and the air spring to ensure that the air spring does not contact the snow cover when it moves. The surface of the air spring has a wave peak structure, and the snow cover is provided with three layers of folds. When the rail vehicle is traveling, the snow cover will be displaced at the same time as the air spring, which greatly increases the driving safety of the rail vehicle in extreme weather such as ice and snow.

[0016] The snow cover has a simple structure and is quick and easy to install and disassemble, which can avoid damage to the air spring and vehicle body and pollution of the environment during traditional manual cleaning.

[0017] The snow cover is made of environmentally friendly rubber material that is resistant to low temperatures, ozone, acid and alkali, and has good flexibility and has a long service life. BRIEF DESCRIPTION OF THE DRAWINGS
