Abstract
The utility model relates to a kind of gas and oil equilibration suspension of mine truck, the jackshaft comprising vehicle frame and be located at below vehicle frame and back axle, the first hydro-pneumatic spring is provided with between vehicle frame and jackshaft, between vehicle frame and back axle, be provided with the second hydro-pneumatic spring, the first hydro-pneumatic spring being positioned at vehicle frame the same side is connected by fluid connecting line with the second hydro-pneumatic spring.Adopt one-sided hydro-pneumatic spring fluid connectivity structure, make two hydro-pneumatic springs be interconnected " energy storage " each other, when vehicle is by uneven road surface, due to the compensating action of " energy storage ", the hydro-pneumatic spring ratio of rigidity single independently hydro-pneumatic spring rigidity of being impacted is little, better buffering road surface is to the impulsive force of vehicle, good adaptive capacity is had to the rugged road conditions in mining area, good protective effect is had to vehicle main load parts, alleviate because road shocks is to the degree of wear of the main load parts of vehicle, decrease the generation of mine car fault, eliminate potential safety hazard.
Description
Technical field:
The utility model relates to a kind of gas and oil equilibration suspension of mine truck.
Background technology:
Use the mining multi-shaft dump truck of hydro-pneumatic spring in the market, the hydro-pneumatic spring of every root bridge is separate, vehicle in the process of moving, when certain vehicle bridge is in compression stroke, the rigidity of hydro-pneumatic spring will become large, once rigidity is too large, car load will be subject to larger impulsive force, therefore, higher requirement is had to the intensity of the vehicle main load parts such as axle shell, hydro-pneumatic spring, vehicle frame.In addition, when mine road is rugged and rough and vehicle carrying is heavier, due in, the separate and hydro-pneumatic spring of back axle is not communicated with, energy between two hydro-pneumatic springs can not cushion, frequent appearance vehicle bridge is subject to impacting the very serious situation of rear unexpected overload, causes suspension can not slow down the impulsive force of road surface to vehicle by actv., serious to vehicle main load component wear, and mine car Frequent Troubles, there is larger potential safety hazard.
Utility model content:
The utility model is in order to make up the deficiencies in the prior art; provide a kind of gas and oil equilibration suspension of mine truck; its reasonable in design; adopt one-sided hydro-pneumatic spring fluid connectivity structure; make two hydro-pneumatic springs be interconnected " energy storage " each other; better buffering road surface is to the impulsive force of vehicle; good protective effect is had to vehicle main load parts; alleviate because road shocks is to the degree of wear of the main load parts of vehicle; decrease the generation of mine car fault; eliminate potential safety hazard, solve problems of the prior art.
The utility model for solving the problems of the technologies described above adopted technical scheme is:
A kind of gas and oil equilibration suspension of mine truck, the jackshaft comprising vehicle frame and be located at below vehicle frame and back axle, the first hydro-pneumatic spring is provided with between vehicle frame and jackshaft, between vehicle frame and back axle, be provided with the second hydro-pneumatic spring, the first hydro-pneumatic spring being positioned at vehicle frame the same side is connected by fluid connecting line with the second hydro-pneumatic spring.
The utility model adopts such scheme, reasonable in design, adopt one-sided hydro-pneumatic spring fluid connectivity structure, make two hydro-pneumatic springs be interconnected " energy storage " each other, when vehicle is by uneven road surface, due to the compensating action of " energy storage ", the hydro-pneumatic spring ratio of rigidity single independently hydro-pneumatic spring rigidity of being impacted is little, better buffering road surface is to the impulsive force of vehicle, good adaptive capacity is had to the rugged road conditions in mining area, good protective effect is had to vehicle main load parts, alleviate because road shocks is to the degree of wear of the main load parts of vehicle, decrease the generation of mine car fault, eliminate potential safety hazard.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
In figure, 1, vehicle frame, 2, jackshaft, 3, back axle, the 4, first hydro-pneumatic spring, the 5, second hydro-pneumatic spring, 6, fluid connecting line.
Detailed description of the invention:
For clearly demonstrating the technical characterstic of this programme, below by detailed description of the invention, and in conjunction with its accompanying drawing, the utility model is elaborated.
As shown in Figure 1, a kind of gas and oil equilibration suspension of mine truck, the jackshaft 2 comprising vehicle frame 1 and be located at below vehicle frame 1 and back axle 3, the first hydro-pneumatic spring 4 is provided with between vehicle frame 1 and jackshaft 2, between vehicle frame 1 and back axle 3, be provided with the second hydro-pneumatic spring 5, the first hydro-pneumatic spring 4 being positioned at vehicle frame 1 the same side is connected by fluid connecting line 6 with the second hydro-pneumatic spring 5.
In vehicle travel process, when jackshaft 2 is subject to ground shock, the first hydro-pneumatic spring 4 be connected with jackshaft 2 not only compresses the gas of self, simultaneously because cavity pressure raises, the second hydro-pneumatic spring 5 on the back axle 3 having part fluid to be entered by fluid connecting line 6 to be connected, and then the gas of compression the second hydro-pneumatic spring 5, so, it is little that the rigidity of the first hydro-pneumatic spring 4 be connected with jackshaft 2 can be subject to the rigidity of uniform impingement power than single oil gas spring, and suffered impulsive force is also little; Owing to establishing balance between the first hydro-pneumatic spring 4 and the second hydro-pneumatic spring 5, hydro-pneumatic spring cavity pressure is equal, equal stiffness, bearing load are equal finally to make two to be connected, also just achieve the axle load mean allocation of two bridges, thus realize the effect balancing, slow down impact.
The utility model does not describe part in detail, is the known technology of those skilled in the art of the present technique.
