Detailed Description
The invention will be described in further detail with reference to the following detailed description and accompanying drawings:
as shown in fig. 1, the utility model provides a wheel house for rail vehicle, wheel house 1 installs on bogie 3, wholly hangs in the top of wheel 2. The wheel cover 1 is integrally of an arc-shaped structure, the shape of the wheel cover is similar to the trend of the wheel set 2, and the wheel cover is installed around the upper part and the side part of the wheel set 2.
As shown in fig. 1 and 3, in the present embodiment, the wheel housing 1 is made of stainless steel plate material, the width of the wheel housing 1 is enough to cover the wheel 2, the cross-sectional shape of the wheel housing 1 matches the shape of the rim and the tread of the wheel 2, the side edge of the wheel housing 1 is tightly attached to the side plate of the frame side beam 4 of the bogie 3 and the brake hanging seat 5, and the bottom end of the wheel housing 1 extends downward to a height of 1/3 from the rail surface, so as to ensure that most of the rim water splash cannot be thrown out of the range of the wheel housing 1. No matter the train runs rightwards or leftwards, the bogie wheel pair 2 rotates clockwise or anticlockwise, and at the moment, most of wheel rim water throwing can be guaranteed to be blocked by the wheel housing 1 and cannot be thrown to other surfaces of the bogie and the bottom of the corresponding train body continuously. The structure of the wheel cover 1 can effectively prevent snow ice at the brake device from melting due to friction heat, and a large amount of snow ice is formed by throwing the wheels to the surface of the nearby bogie and the bottom of the vehicle body.
As shown in fig. 1 and 2, a first mounting plate 6 is mounted at one end of the wheel house 1, a second mounting plate 7 is mounted at a side portion of the wheel house 1, the first mounting plate 6 is fixedly connected to the brake shoe 5 by a bolt 8, and the second mounting plate 7 is fixedly connected to a side plate of the frame side member 4 by a bolt 9. The first mounting plate 6, the second mounting plate 7, the brake device hanging seat 5 and the framework side beam 4 can be fixedly connected in a clamping, bonding and other modes. The first mounting plate 6, the second mounting plate 7 and the wheel housing 1 can be fixedly connected together through bolts, and can also be directly welded together or bonded together.
In the embodiment, as shown in fig. 3, the wheel housing 1 preferably adopts a middle-bending structure, a first portion 1a of the wheel housing 1 located at the upper part of the wheel 2 and a second portion 2b located at the side part of the wheel 2 are transited by an arc angle 1c, and an included angle (not marked in the figure) between two tangent lines at two ends of the arc angle 1c is 130-. Of course, the wheel house 1 may have a circular arc structure that conforms to the shape of the wheel 2 as a whole.
In order to avoid the ice coating phenomenon on the inner surface of the wheel housing 1 caused by the water thrown from the bogie wheel set 2 to the inner surface, in this embodiment, a polymer hydrophobic material coating (not shown) is coated on the inner surface of the wheel housing 1. When ice and snow melting water is thrown to the inner surface of the wheel cover 1 through the rotation of the wheel rim of the wheel 2, the high-molecular hydrophobic material coating can prevent the ice and snow melting water from being attached to the inner surface of the wheel cover 1 to cause icing, reduce the ice and snow melting attachment amount of the inner surface of the wheel cover, avoid a large amount of accumulated ice from being gradually formed between the bottom of the vehicle body and a bogie, block a bogie cabin, increase the axle weight of the bogie and degrade the dynamic performance of the bogie.
In order to prevent the unexpected snow accumulation and icing inside the wheel housing 1 caused by the failure of the macromolecule hydrophobic material coating layer to realize the surface hydrophobic function, the distance between the wheel housing 1 and the wheel 2 is gradually reduced, and the normal rotation of the wheel pair 2 can be possibly hindered. In the present embodiment, as shown in fig. 3, all or part of the wheel housing 1 is in a sandwich layer 10 structure, and a heating element (not shown) is installed in the sandwich layer 10, and preferably, an electric heating wire is used as the heating element, and the electric heating wire is connected with a control room of the vehicle and is controlled by the control room in a unified way. When the inner surface of the wheel cover 1 is frozen, heating is started, the heating element is used for timely heating and transferring heat to the inner side to melt ice and snow formed on the inner surface of the wheel cover 1, so that a large amount of ice is prevented from being accumulated, and the ice and snow are prevented from accumulating to influence the normal operation of the bogie wheel pair.
The utility model discloses an at 2 peripheral installation wheel covers 1 of wheel, can effectively prevent and treat that arresting gear department snow freezes because of the frictional heating melts to because wheel 2 rotates and gets rid of near bogie surface and bottom of the body and form a large amount of snow and freeze, reduce the frozen risk of bogie, guarantee that the dynamic performance of bogie does not change, improve rail train vehicle security and the conveying efficiency at the operation of cold sleet weather.
The utility model discloses still provide a rail vehicle simultaneously, four wheel pairs 2 of installation on the bogie 3, all install as above in the top of every wheel pair 2 the wheel house 1.
As mentioned above, similar technical solutions can be derived from the solutions given in the drawings, and the present invention is also applicable to other rail vehicles. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical substance of the present invention are still within the scope of the technical solution of the present invention.
