Specific embodiment
Present invention is further described in detail with specific embodiment with reference to the accompanying drawing:
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, the front of framework 2 is arranged in troubleshooting plate 1, and troubleshooting plate 1 is laterally arranged along vehicle 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 in vehicle formula transverse direction, intermediate to protrude to traffic direction, in this way
Barrier on track can be thrown away from the two sides of troubleshooting plate 1, not only be can reduce in vehicle operation by troubleshooting plate 1
Air drag can also avoid barrier from entering the components such as framework inner impact framework and the motor at rear and not be damaged.
In order to improve the overall structural strength and rigidity of troubleshooting plate 1, troubleshooting plate 1 uses vertical section for the structure of U-shaped, troubleshooting
The top plate 1a and bottom plate 1b of plate 1 have the first gap 3 in the position at center, are conducive to 1 bending of troubleshooting plate, also have in its two sides more
A 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 under the premise of guaranteeing 1 structural strength of troubleshooting plate, meet light-weighted to vehicle
It is required that.
As shown in Figure 2 and Figure 4, the outer surface of troubleshooting plate 1 is covered with buffer layer 5, and buffer layer 5 uses rubber layer, this implementation
In example, there is cavity 6 preferably between troubleshooting plate 1 and buffer layer 5, buffer layer 5 forms air sac type structure in the front of troubleshooting plate 1.
Vehicle is in high-speed cruising, the troubleshooting plate 1 for the not instead of metal that barrier is directly hit, the rubber buffer with airbag structure
Layer 5, under the collective effect of rubber material and air sac type structure, improves the cushion performance of obstacle deflector, alleviates barrier
Collision is destroyed to caused by troubleshooting plate 1, the anti-collision energy of troubleshooting plate 1 greatly improved, and then shock loading has been effectively relieved
Damage for the motor at rear guarantees vehicle driving safety.
As shown in Figure 2 and Figure 4, in the present embodiment, buffer layer 5 completely covers the vertical panel 1c's and bottom plate 1b of troubleshooting plate 1
Part, the open at both ends of buffer layer 5 in the vehicle width direction.The height of buffer layer 5 is much larger than the vertical panel 1c and bottom plate of troubleshooting plate 1
The height of 1b and, after mounting, buffer layer 5 naturally droops, and then forms air bag between buffer layer 5 and troubleshooting plate 1 naturally
Formula structure.It is designed by cleverly structure, not only achievees the purpose that buffering, but also the overall structure of obstacle deflector is simpler
It is single, it mounts and dismounts also very convenient.
As shown in Figure 2 and Figure 4, the top of buffer layer 5 is solid by the top of multiple bolts 8 and the vertical panel 1c of troubleshooting plate 1
Fixed, the bottom of buffer layer 5 covers the bottom plate 1b of troubleshooting plate 1 around vertical panel 1c, and buffer layer 5 passes through multiple bolts 9 and bottom plate 1b
It is fixedly connected.In the present embodiment, it is preferable that the most bottom edge of buffer layer 5 is lower than the most bottom edge of troubleshooting plate 1 on vertical, troubleshooting plate 1
Bottom plate 1b is that the structure being upturned and horizontal plane have an angle.In this way, being buffer layer with the bar contact on rail level
5, for barrier in damping of shocks layer 5, buffer layer 5 can be generated frontal impact power, row by strength backward to the component of back
The bottom plate 1b of baffle 1 is upturned the anti-collision that can be avoided the frontal impact, and then can be further improved troubleshooting plate 1
Can, guarantee that troubleshooting plate 1 will not damage.
As shown in Figure 1 and Figure 5, the mounting structure 10 of corresponding troubleshooting plate 1, there are two mounting plate 11, rows for setting on framework 2
