Chinese patent CN101941468A discloses a kind of cab suspension device, is used for regulating vehicle cab luffing angle or side tilt angle.But this device can only be applied in the vehicles such as civil car, military trucks and wheel military vehicle, poor for applicability for engineering truck; And compared to the shock absorber of engineering truck, structure is comparatively complicated, and cost is higher relatively, is difficult for realizing.
Summary of the invention
The utility model provides a kind of engineering truck vibration damping safety cab, overcomes the shortcoming such as complex structure, cost height of the traditional shock attenuation unit described in the background technology, realizes a kind of cab structure with good cushioning performance and safe enough performance.
The utility model is achieved through the following technical solutions for solving the problems of the technologies described above:
A kind of engineering truck vibration damping safety cab, comprise cab frame 1, vehicle frame 2, vibration-proof structure 3 and carrying structure 4, cab frame 1 is connected by vibration-proof structure 3 with vehicle frame 2, carrying structure 4 is fixing for welding with vehicle frame 2, passes through sleeve 4-2 sliding block joint between carrying structure 4 and the cab frame 1.
Described vibration-proof structure 3 comprises operator's compartment base plate 1-1 and fixing bolt 3-1 and the nut 3-6 of frame brackets 2-1, and be sleeved on rubber damper A3-3 and rubber damper B3-4 on the bolt 3-1, wherein rubber damper A3-3 is between operator's compartment base plate 1-1 and frame brackets 2-1, and rubber damper B3-4 is between frame brackets 2-1 and nut 3-6;
Alternatively, loosening for preventing nut 3-6, the area of thrust surface of rubber damper when vertical load is born in increase, intensity and the life-span of improving vibration-proof structure 3, bolt 3-1 and nut 3-6 inboard also are equipped with metallic gasket A3-2 and metallic gasket B3-5;
When vertical tension, rubber damper A3-3 plays main damping of vibrations;
When vertical pressurized, rubber damper B3-4 plays main damping of vibrations.
Described carrying structure 4 is welded by carrying column 4-1 and sleeve 4-2, and carrying column 4-1 links to each other with vehicle frame 2 by welding, and one is used from side direction and the longitudinal travel of operator's compartment when retraining operator's compartment and being subjected to lateral loading and longitudinal loading.
Advantage of the present utility model and beneficial effect are: strengthened the intensity of operator's compartment shock absorber, made its carrying vertically and the reinforcement of the ability of lateral loading; And the utility model highly versatile, realized that same shock attenuation unit is applicable to multiple different engineering truck, and the design by the carrying column, realized when operator's compartment is subjected to impacting, its lateral loading and longitudinal loading are mainly born by damping frame, vertical load is mainly absorbed by rubber damper, strengthens shock attenuation unit to the load-carrying capacity of side direction load and longitudinal loading under the situation that guarantees vertical cushioning performance, thereby guaranteed certain traveling comfort under the prerequisite of safety; It is simple in structure, saves cost and drops into, and has good application prospects.
