Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.Should be understood that, embodiment described herein, only for instruction and explanation of the utility model, is not limited to the utility model.
In the utility model, when not doing contrary explanation, the buffer limit block that the noun of locality used typically refers to the utility model as " upper and lower, " and provides be installed to vehicle frame upper piston rod in below, reset portion arrangement benchmark definition up, specifically can with reference to the page shown in figure 1, " inside and outside " is then in the corresponding part profile for accompanying drawing and outward.
As shown in Figure 1, the utility model provides a kind of buffer limit block and uses the vehicle of this buffer limit block.This buffer limit block is installed on vehicle frame by mounting bracket 8, wherein, this buffer limit block comprises the cylinder body 7 for holding fluid, be positioned at the piston 2 of this cylinder body 7 inside, and upper end is connected to this piston 2 and lower end extends the piston rod 1 of this cylinder body 7 downwards, piston 2 space of cylinder body 7 inside is divided into upper chamber 4 and lower chambers 5, two Room realizes being communicated with by the damping hole that piston 2 is formed.
In the vehicle wherein provided at the utility model, piston rod 1 points to vehicle bridge, therefore when vehicle travels when jolting road surface, the up vehicle bridge that will drive of wheel moves upward, vehicle bridge moves upward and collides piston rod 1 and impact force passed on this buffer limit block, at this moment, piston rod 1 drives piston 2 to move upward in cylinder body 7, hydraulic oil in upper chamber 4 will produce damping force along with the damping hole moved up through on piston 2 of piston rod 1 flows into lower chambers 5, and up further along with piston rod 1, damping force also can be increasing, the damping force changes mechanical energy that the impact force that wheel will be brought drives piston rod 1 upstroke to produce that does work is that heat energy discharges, thus stop the up of wheel, and the time of impact load can be extended, make the movement travel of this buffer limit block longer, while the vibrations that satisfied reduction wheel produces when experiencing and jolting road surface, also the run duration stoping wheel up is extended, the initial of collision buffering limiting stopper is avoided suddenly to stop the up uncomfortable feeling brought to occupant of wheel, alleviate the upstroke of wheel, also improve the comfort level that occupant rides.
It should be noted that, the buffer limit block that the utility model provides, except for above-mentioned vehicle China and foreign countries, can also be used for the field that other needs carry out cushioning.In addition, the mode that can realize technical solutions of the utility model has multiple, the structure of such as this buffer limit block, shape and concrete compound mode etc., the utility model for convenience of description, in this introduction preferred implementation wherein, this preferred implementation, only for illustration of the utility model, is not limited to the utility model.
Further, in preferred implementation of the present utility model, in cylinder body 7, being provided with the reset portion being provided for piston 2 and moving downward, therefore by piston 2 self-return that this reset portion can make pressurized rise, impacting in order to receiving next time.Particularly, in one embodiment, as shown in Figure 1, described reset portion comprises the Compress Spring 6 being positioned at upper chamber 4, the upper end of this Compress Spring 6 is connected on the top board 10 in cylinder body 7, lower end then extends towards piston 2, the Compress Spring 6 as reset portion will be compressed like this when piston rod 1 drives piston 2 to move upward, elastic resistance will be produced by the Compress Spring 6 after compressing, and along with the change of compressive strain large and increase elastic resistance, thus while piston 2 can be made downwards to reset, can limited piston 2 and piston rod 1 up further, thus limit the up further of wheel, guarantee the limit position that wheel is up, namely, the buffer limit block that the utility model provides is except the first-level buffer effect that damping hole brings, can also have and provide further level 2 buffering effect by reset portion.
After up process completes, piston 2 will drive piston rod 1 to return to home position rapidly by elastic resistance by reset portion, and the traveling making wheel band motor vehicle steadily safe, on road surface, improves occupant's ride comfort better.Preferably, reset portion of the present utility model is a rectangle Compress Spring, and in other preferred implementation, reset portion also can for having the miscellaneous part of elastic nature, and to this, the utility model does not limit.In the mode of execution that other are possible, reset portion can also comprise the extension spring being arranged in lower chambers 5, namely one end of this extension spring is connected to the diapire the other end connection piston 2 of lower chambers 5, like this, on the piston 2 during row, the effect of the reset portion that above-mentioned Compress Spring 6 realizes can be realized equally by extension spring.
Get back to Fig. 1; in order to realize the buffer function of the utility model buffer limit block further; in the lower end of piston rod 1, rubber base 3 is also installed; when the up drive vehicle bridge collision buffering limiting stopper of wheel; first clash into the rubber base 3 of bottom, rubber material has good elastic nature, just can play certain buffer function when clashing into rubber base 3; also deform after preventing piston rod 1 from frequently being clashed into simultaneously or damage, playing certain protective action.
As shown in Figure 1, upper chamber 4 inside is also provided with air bag 9, air bag 9 is installed on top board 10, and be positioned at the outside of reset portion, along with piston rod 1 drives piston 2 to move upward, the hydraulic oil of upper chamber 4 will compressing gasbag 9, air bag 9 will produce reaction force, and increase along with moving upward of piston 2, therefore, also wheel upstream time can indirectly be extended, buffering reduces the uncomfortable feeling that impact force is brought instantaneously, simultaneously also can at the end of wheel be up, reaction force auxiliary reset portion is utilized to drive piston rod 1 to return to home position rapidly in piston 2, namely air bag 9 can provide except damping hole, third level buffer function outside reset portion.
To sum up, the buffer limit block that the utility model provides, simplicity of design, be skillfully constructed, be arranged on vehicle frame by mounting bracket 8, vehicle is travelled and in bumpy sections, by wheel is up, vehicle bridge percussion piston bar 1 is utilized to the impact force that wheel causes, piston 2 is driven to move thus, it is made to produce damping force, and to be done work by damping force be heat energy by changes mechanical energy gradually, apparatus with shock absorbing effectively, can extend the impulsive load time again, avoids wheel to stop suddenly the up uncomfortable feeling caused passenger.Simultaneously under the effect of the power of air bag 9 and reset portion, can the up limit position of limiting wheel, and make piston 2 that piston rod 1 can be driven to return to original state rapidly, vehicle normal safe is run.Therefore, the buffer limit block that the utility model provides has higher practicability and promotional value.
Below preferred implementation of the present utility model is described by reference to the accompanying drawings in detail; but; the utility model is not limited to the detail in above-mentioned mode of execution; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
It should be noted that in addition, each concrete technical characteristics described in above-mentioned embodiment, in reconcilable situation, can be combined by any suitable mode, in order to avoid unnecessary repetition, the present invention illustrates no longer separately to various possible compound mode.
In addition, also can carry out combination in any between various different mode of execution of the present utility model, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
