Problems solved by technology

[0005] In the passive safety design of rail vehicles, under the collision conditions of rail vehicles, the FRP front cover is flexible and not fragile, which affects the anti-climber function of rail vehicles, the accurate coupling of couplers and the effect of energy-absorbing structures, and cannot provide accurate safety design data

Embodiment 1

[0027] Such as figure 1 with figure 2 As shown, the present invention provides a front cover structure of a rail vehicle head, including a front cover 1 installed on the head of the car body. In order to meet the requirements of vehicle coupling, the front cover 1 is composed of two separate parts, left and right, respectively. It is the left front cover 2 and the right front cover 3, which are symmetrically arranged along the longitudinal center line of the car body. , to ensure that the running resistance is not increased when the vehicle is running. When the coupler is needed, the left front cover 2 and the right front cover 3 are driven by the opening and closing mechanism to open the coupler to expose the head of the vehicle to both sides of the car body. Both the left front cover 2 and the right front cover 3 are made of FRP, which can not only ensure the required strength and rigidity when the vehicle is running at high speed, but also reduce the weight to meet the re...

Embodiment 2

[0041] The difference from Embodiment 1 is that, not shown in the figure, the shape of the long slit 7 is a straight line, inclined to the side connected to the vehicle body, and the long slits 7 located on both sides of the gap 6 are arranged symmetrically to each other, and the symmetrically arranged Two long slits 7 form an included angle, and the extended lengths of each long slit 7 can be the same. In this embodiment, the extended lengths of multiple long slits 7 on the same side are preferably different, and gradually decrease from the front to the vehicle body.

Embodiment 3

[0043] The difference from Embodiment 1 is that, not shown in the figure, the left front cover 2 and the right front cover 3 are respectively divided into upper, middle and lower three pieces to form two slits 6, and each slit 6 is one on the horizontal plane. Arc, two slits 6 are parallel to each other, the height of the center line between the two slits 6 from the rail surface is consistent with the height of the coupler from the rail surface, and the distance between the two slits 6 is determined according to the size of the coupler.

[0044] Three long slits 7 are respectively arranged on both sides of the two slits 6, and the three long slits 7 located between the two slits 6 run through the two slits 6, and three long slits 7 are respectively arranged on the outside of the two slits 6, But the length of the long slit 7 arranged outside the slit 6 is shorter than the length of the long slit 7 arranged in the middle of the two slits 6 .

[0045] Except above-mentioned embo...

Abstract

The invention relates to a front cover structure for a railway vehicle head. The front cover structure comprises a front cover mounted at the head part of a vehicle body, and the front cover is divided into a plurality of pieces which are fixedly connected together through connecting structures. The front cover structure is simple and practical in integral structure, the front cover is divided into a plurality of pieces and then is sewn, and the strength of the connecting structures among the pieces is controlled, so that the local tearing strength of the front cover made of glass fiber reinforced plastics and the structural failure deformation process under the crashing condition are effectively controlled, the tearing failure is achieved according to the design requirements in the crashing process, the tearing part is bent by the crushing force according to the design requirements, the structure doesn't damage distribution and stretching of fiber in a glass fiber reinforced plastic body, the performance of the glass fiber reinforced plastics is reserved, small influence is produced on the integral structure of the glass fiber reinforced plastic body, the design only affects the strength of local glass fiber reinforced plastics according to the working condition requirements, tearing is performed step by step according to the design requirements after crashing, and the safety design and car coupler hanging requirements are met.

Description

technical field [0001] The invention relates to a rail vehicle head, in particular to a rail vehicle front cover structure, and belongs to the technical field of rail vehicle manufacturing. Background technique [0002] For high-speed rail vehicles such as EMUs, there is a front cover on the front part of the car, and the front cover covers the coupler on the head of the car to achieve an aesthetic effect. resistance. [0003] Rail vehicles need to be connected with couplers when they are connected or rescued. In order to meet the requirements of vehicle connection, the front end of the front of the rail vehicle currently adopts a split-type automatic opening and closing front cover structure. The front cover structure includes left and right symmetrical The left front cover and the right front cover are driven by the opening and closing mechanism. When the vehicle is running normally, the left front cover and the right front cover are closed. When necessary, the left front...
