Embodiment
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings:
As shown in figure 1, a kind of low-floor rail vehicle troubleshooting provided by the invention and motor protection device, including troubleshooting plate
1, troubleshooting plate 1 is arranged on the front of framework 2, and troubleshooting plate 1 is laterally set along overall width direction, and troubleshooting plate 1 passes through two groups of mounting structures
10 are fixed on framework 2.
As shown in Figures 2 to 4, troubleshooting plate 1 is V-shaped on vehicle formula horizontal direction, middle to be protruded to traffic direction, so
Barrier on track can be thrown away, can not only reduced in vehicle operation by troubleshooting plate 1 from the both sides of troubleshooting plate 1
Air drag, barrier can also be avoided to enter the parts such as framework inner impact framework and the motor at rear and be not damaged by.
In order to improve the overall construction intensity of troubleshooting plate 1 and rigidity, troubleshooting plate 1 uses structure of the vertical section for U-shaped, troubleshooting
The top plate 1a and bottom plate 1b of plate 1 have the first gap 3 in the position at center, beneficial to the bending of troubleshooting plate 1, also have in its both sides more
Individual second gap 4, the mounting structure 10 of corresponding lower section, facilitates staff to dismount troubleshooting plate 1.In the vertical panel 1c of troubleshooting plate 1
On be provided with multiple lightening holes, to mitigate weight on the premise of the structural strength of troubleshooting plate 1 is ensured, meet light-weighted to vehicle
It is required that.
As shown in Figure 2 and Figure 4, the outer surface of troubleshooting plate 1 uses rubber layer, this implementation covered with cushion 5, cushion 5
In example, there is cavity 6 preferably between troubleshooting plate 1 and cushion 5, cushion 5 forms air sac type structure in the front of troubleshooting plate 1.
For vehicle in high-speed cruising, what barrier directly hit is not the troubleshooting plate 1 of metal, but the rubber buffer with airbag structure
Layer 5, under the collective effect of elastomeric material and air sac type structure, improves the shock-absorbing capacity of obstacle deflector, alleviates barrier
To destruction caused by troubleshooting plate 1 the anti-collision energy of troubleshooting plate 1 greatly improved, and then effectively alleviate shock loading in collision
Damage for the motor at rear, ensure vehicle driving safety.
As shown in Figure 2 and Figure 4, in the present embodiment, cushion 5 completely covers the vertical panel 1c's and bottom plate 1b of troubleshooting plate 1
Part, open at both ends of the cushion 5 on overall width direction.The height of cushion 5 is much larger than the vertical panel 1c and bottom plate of troubleshooting plate 1
1b height and, after mounting, cushion 5 naturally droops, and then forms air bag between cushion 5 and troubleshooting plate 1 naturally
Formula structure.By cleverly structure design, not only reach the purpose of buffering, also make it that the overall structure of obstacle deflector is simpler
Single, installation and removal are convenient to.
As shown in Figure 2 and Figure 4, the top of cushion 5 is consolidated by the top of multiple bolts 8 and the vertical panel 1c of troubleshooting plate 1
Fixed, the bottom of cushion 5 covers the bottom plate 1b of troubleshooting plate 1 around vertical panel 1c, and cushion 5 passes through multiple bolts 9 and bottom plate 1b
