Fig. 1 is a kind of structural representation of the pneumatic front preventer of vehicle of the invention；
Fig. 2 is the B direction views of Fig. 1；
Fig. 3 is the A-A direction views of Fig. 2.
Specific embodiment
As shown in Figure 1, Figure 2 and Figure 3, a kind of pneumatic front preventer of vehicle of the invention includes lower protection crossbeam 1 and 2
Individual drive mechanism.The two ends of lower protection crossbeam 1 are connected respectively by respective drive mechanism with 2 longitudinal beams 7.
Drive mechanism include fulcrum post axle bed 2, support plate 3, double-acting cylinder 4, spacer pin shaft stool 5, cylinder support 6,
Spring compression support 13, bearing pin 14 and spring 15.One end welding (or by securing member) of support plate 3 is fixed on lower protection crossbeam
On 1, the other end of support plate 3 is fixed on longitudinal beam 7, and the other end of support plate (3) is Y-shaped, the upper one end of Y-shaped
It is hinged with fulcrum post axle bed 2, fulcrum post axle bed (2) is fixed on longitudinal beam 7.Spacer pin shaft stool 5 isShape, supporting
The other end on the Y-shaped top of plate 3 is with spacer pin shaft stool 5Translot in shape is slidably connected.Double-acting cylinder 4 is pushed away
Rod end is hinged by bearing pin with support plate 3, and cylinder body end and the cylinder support 6 of double-acting cylinder 4 are hinged；Cylinder support 6 is fixed on
On longitudinal beam 7.
As shown in figure 3, spring compression support 13 is fixed on spacer pin shaft stool 5, spring 15 is sleeved on the one of bearing pin 14
On the periphery of end, one end of bearing pin 14 loads in the installing hole of spring compression support 13 together with spring 15, the two ends of spring 15
Withstand on respectively on the installing hole inner face of spring compression support 13 and the middle part shaft shoulder end face of bearing pin 14, on support plate 3 upper limit is provided with
Position hole 12 and lower limit hole 11.When lower protection crossbeam 1 is in upper and lower two extreme positions, in the presence of spring 15, bearing pin
14 other end is each passed through upper limit hole 12 or lower limit hole 11 and inserts in the spacing hole on the surface of longitudinal beam 7, and it is right to realize
Support plate 3 it is spacing, in order that upper limit hole 12 and lower limit hole 11 align with the spacing hole on the surface of longitudinal beam 7, be easy to
The other end insertion of bearing pin 14, is welded with limited block 9 and limited block 10, when the one end side of support plate 3 on fulcrum post axle bed 2
Spacing hole difference upper limit hole 12 and lower limit hole when contacting with limited block 9 and limited block 10 respectively, on the surface of longitudinal beam 7
11 align.
The operation principle of the present invention is, as depicted in figs. 1 and 2, crossbeam 1 is protected instantly when being respectively at lower position, bullet
In the lower limit hole 11 and the corresponding aperture of longitudinal beam that spring 15 is pressed on bearing pin 14 on support plate 3, so, lower protection crossbeam 1
Stationary state is remained in relative to vehicle frame, external impact can be born, when protecting crossbeam 1 under external impact, impact force will
Undertaken by 2 fulcrum post axle beds, 2,2 bearing pins 14 and double-acting cylinder 4, double-acting cylinder 4 can also play the work of buffering collision of closed
With.
When low vehicle speeds are on bad section, need the height for improving lower protection crossbeam 1, then can be by driving
The bracing wire operating mechanism of chamber interior, draws the draw ring 16 on the one end of bearing pin 14, makes the disengaging of the top other end of the Y-shaped of support plate 3
The position-limiting action of bearing pin 14, then lower protection crossbeam 1 is improved by double-acting cylinder 4, the upper one end of the Y-shaped of support plate 3 is relative
Jointed shaft on supporting shaft seat assembly 2 is pivoted about, when support plate 3 rotates to its side to be contacted with limited block 9,
Lower protection crossbeam 1 can not be enhanced again, now unclamp bearing pin 14, and bearing pin 14 is pressed on spring 15 upper limit on support plate 3
In the corresponding spacing hole of hole 12 and longitudinal beam 7, so as to realize the raising operation of the lower protection height of crossbeam 1.
