Detailed Description
The technical problems to be solved by the invention are as follows: the conventional multifunctional vehicle oil cylinder shown in fig. 1 can well improve the smoothness and comfort of a vehicle, and can properly improve the chassis height so as to improve the vehicle passing performance, but cannot play a role in lifting or lifting an axle when crossing a barrier vertically and crossing a trench. The technical thought provided by the invention regarding the technical problem is as follows: on the basis of the existing multifunctional vehicle oil cylinder, the lower area is further designed, and a new hydraulic oil cavity is formed in the lower area, so that the effect of lifting an axle can be achieved through filling hydraulic oil when the vehicle vertically passes over the obstacle and spans the trench, and the road surface passing performance of the vehicle is finally improved.
In order to make the technical objects, technical solutions and technical effects of the present invention more apparent, so as to facilitate understanding and implementation of the present invention by those skilled in the art, the present invention will be described in further detail with reference to the accompanying drawings and specific examples.
As shown in fig. 2, fig. 2 shows a schematic structural view of a multifunctional vehicle oil cylinder according to an embodiment of the present invention. Specifically, the multifunctional vehicle cylinder includes a cylinder housing 3 fixed to a vehicle frame (not shown in the figure), and a first isolation pad 5 and a second isolation pad 9 slidably provided inside the cylinder housing 3 and disposed up and down, respectively; the first isolation pad 5 and the second isolation pad 9 divide the inside of the cylinder housing 3 into an upper region, a middle region, and a lower region isolated from each other; the oil cylinder housing 3 is provided with a first oil hole 2 communicating with the upper region so that the upper region serves as a first hydraulic oil chamber 4; the multifunctional vehicle oil cylinder further comprises a piston 7 which is slidably arranged in the middle area and divides the middle area into a first high-pressure air cavity 6 above and a second high-pressure air cavity 8 below which are isolated from each other; the second isolation pad 9 is provided with a first through hole, the bottom of the oil cylinder shell 3 is provided with a second through hole, and the bottom of the piston 7 is provided with a connecting column 71 respectively penetrating through the first through hole and the second through hole; the connecting post 71 is connected to an axle (not shown); the connecting column 71 is arranged between the first through hole in a sealing way, and the connecting column 71 is arranged between the second through hole in a sealing way; the cylinder housing 3 is also provided with a second oil hole 11 communicating with the lower region so that the lower region serves as a second hydraulic oil chamber 10. In the present embodiment, the second high-pressure air chamber 8 and the second hydraulic oil chamber 10 are constructed by providing the second spacer 9, as compared with the conventional multi-functional vehicle oil cylinder described in the related art. The connecting post 71 and the piston 7 may be integrally formed, or may be detachably connected.
When the automobile normally runs, the hydraulic oil in the second hydraulic oil cavity 10 is completely emptied, so that the up-and-down movement of the piston is not influenced, and the same effect as that of a traditional oil-gas cylinder is realized. The second high-pressure air chamber 8 contains a small amount of air for preventing a severe collision between the piston 7 and the second spacer 9. Meanwhile, the second high-pressure air cavity 8 is matched with the first high-pressure air cavity 6, and acting force is generated on the movement of the piston through the change of air pressure at two sides of the piston, so that the damping effect of the piston is enhanced.
When the first hydraulic oil cavity 4 releases hydraulic oil, the air pressure in the first high-pressure air cavity 6 is reduced, the load of the multifunctional vehicle oil cylinder is reduced, but the axle is still grounded and cannot be lifted. When the second hydraulic oil chamber 10 is filled with hydraulic oil, the second high-pressure air chamber 8 is compressed, and the piston 7 is pushed up by the air pressure. As the second high pressure air chamber 8 continues to rise, the axle will be lifted until the pressure differential between the second high pressure air chamber 8 and the first high pressure air chamber 6 is greater than the weight of the axle.
Further, in the present embodiment, the multifunctional vehicle cylinder further includes a first lifting lug 1 provided on the cylinder housing 3 for fixing the cylinder housing 3 to a vehicle frame (not shown in the drawings). It will be appreciated that in other embodiments, the cylinder housing 3 may be fixedly attached to the frame in other ways, such as by welding, bolting, etc.
Further, in the present embodiment, the bottom of the connecting post 71 is provided with a second lifting lug 12 connected to an axle (not shown). It will be appreciated that in other embodiments, the connecting post 71 may be fixedly coupled to the axle in other ways, such as by welding, bolting, etc.
The invention further provides a use method of the multifunctional vehicle oil cylinder, which comprises the following steps:
s1, acquiring an axle lifting trigger signal;
step S2, when an axle lifting trigger signal is obtained, enabling the first hydraulic oil cavity 4 to release hydraulic oil; and the second hydraulic oil chamber 10 is filled with hydraulic oil so that the axle is lifted.
In the above-mentioned method of use, the axle lift trigger signal may be an electrical signal or a mechanical transmission signal.
In order to describe the use of the multifunctional vehicle oil cylinder more vividly, two specific implementations will be listed below for further description of the use.
Example 1 through vertical obstruction
As shown in fig. 3 and 4, when the vehicle moves at the speed V and encounters an obstacle 100 having a height exceeding the radius of the wheel, an upward component (excluding an upward component generated by rotation of the front wheel) cannot be generated on the front wheel due to the driving force of the whole vehicle, and thus the vehicle cannot normally pass through the obstacle.
At this time, the first hydraulic oil chamber 4 in the multi-functional vehicle oil cylinder connected to the front axle is released with hydraulic oil by operating the trigger device in the cab, the second hydraulic oil chamber 10 is filled with hydraulic oil, and the pressure in the second hydraulic oil chamber 10 is raised to raise the piston 7, thereby lifting the front axle, and the front axle wheels 200 are lifted off the ground with an axle height exceeding the height of the obstacle 100. The dead weight of the vehicle is then carried by the remaining three axles. At this time, the forward driving force of the automobile generates upward component force Fv on the front wheel, so that the front wheel is jumped to a vertical obstacle, and the passing performance of the automobile is improved. As shown in fig. 4, fig. 4 shows that the force Ft generated by the obstacle 100 on the wheel 200 is divided into an upward force component Fv and a horizontal resistance Fh. The intermediate or trailing wheels may also pass through this operation, in turn, through a vertical obstruction.
Example 2 through a trench
As shown in fig. 5, when the vehicle moves at the speed V and encounters a moat 300 having a width greater than the diameter of the wheel, the wheel 200 is lowered by pulling the suspension system by its own weight, and when the wheel 200 is lowered to a depth greater than the radius of the wheel 200, the wheel 200 cannot obtain an upward component (except for an upward component generated by the rotation of the front wheel) and the vehicle cannot normally pass through the moat.
At this time, by operating the triggering device in the cab, the first hydraulic oil chamber 4 in the multi-functional vehicle oil cylinder connected to the front axle is released with hydraulic oil, the second hydraulic oil chamber 10 is filled with hydraulic oil, and the pressure in the second hydraulic oil chamber 10 is raised to raise the piston 7, thereby raising the front axle, raising the front axle wheel 200 with its axle height from the ground being smaller than the wheel radius, so that the acting force Ft of the moat 300 on the front axle wheel 200 is divided into an upward component force Fv and a horizontal resistance force Fh. The upward force component Fv causes the front axle wheel 200 to jump up the moat, thereby improving the vehicle's passing performance. The intermediate or trailing wheels may also be run through the moat in turn by this operation.
The invention further designs the lower area on the basis of the existing multifunctional vehicle oil cylinder, and constructs a new hydraulic oil cavity in the lower area, so that the effect of lifting the axle can be realized by filling hydraulic oil when the vehicle vertically passes over the obstacle and spans the trench, and the road surface passing performance of the vehicle is finally improved.
It will be understood that modifications and variations will be apparent to those skilled in the art from the foregoing description, and it is intended that all such modifications and variations be included within the scope of the following claims.
