Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a liquid-filled mount.
[0002]
[Prior art]
In a work vehicle such as a hydraulic excavator, the cab is attached to the vehicle body frame via a liquid-filled mount in order to reduce the transmission of vibrations and shocks generated during work and travel to the cab.
In general, a liquid-sealed mount is composed of an elastic body such as rubber, a stud penetrating the elastic body, a cup-shaped case in which the elastic body and the stud are inserted into an opening to enclose the viscous liquid, and a viscous liquid. A dampening member mounted on the stud in a soaked state is provided, the case is fixed to the vehicle body frame side, and the stud is fixed to the cab side. A large load is applied in the vertical direction (axial direction of the mount) compared to the horizontal direction of the vehicle body, and the elastic body may be greatly displaced and damaged, so that the stud can be slid in the axial direction and the axial direction A mount has been devised that incorporates a coil spring that supports the load.
[0003]
FIG. 12 is a cross-sectional view showing a liquid-sealed mount described in Japanese Patent Laid-Open No. 7-127683, which can prevent the elastic body from being damaged even when a large load acts in the axial direction and the stud is largely displaced. .
A damping member 44 attached to the lower end of the stud 43 is accommodated in a cylindrical case 41 having a bottom surface. The damping member 44 having the orifice hole 44 a penetrating vertically forms a disk shape having a diameter slightly smaller than the inner diameter of the case 41, and an annular gap is formed between the outer peripheral portion and the case 41. A coil spring 48 is provided between the case 41 and the damping member 44, and upper and lower ends thereof are connected to the bottom surface of the case 41 and the damping member 44, respectively. A sleeve 47 is attached to the inner periphery of a cylindrical elastic body 46 attached to the upper portion of the case 41, and the stud 43 is hermetically in contact with the inner periphery of the sleeve 47 and is held so as to be slidable up and down. ing. A bellows 49 is integrally formed at the lower end of the elastic body 46, and the lower end portion of the bellows 49 is airtightly attached to the attachment portion between the damping member 44 and the stud 43. A viscous liquid L is sealed in the case 41 sealed by the elastic body 46, the bellows 49 and the damping member 44.
Even if a large load is applied to the stud 43, it is supported by the spring 48 and no load is applied to the elastic body 46, so that the elastic body 46 can be prevented from being damaged. The damping in the vertical direction is performed by the damping member 44 and the spring 48, and the cushioning in the lateral direction is performed by the elastic body 46. Both of these buffering actions reduce vibration and impact transmitted to the cab.
[0004]
[Problems to be solved by the invention]
However, the above-described prior art has the following problems.
In order to improve riding comfort, the spring constant of the spring 48 that supports the load in the vertical direction applied to the stud 43 is an elastic body of a mount (elastic body support type) that supports the stud only by an elastic body without using a spring. Is smaller than the spring constant (for example, about 1/10). For this reason, if the weight of the cab is different, the cab mounting height (the degree of sinking of the stud 43) varies with respect to a predetermined specified value (for example, in the case of the elastic support type, the displacement of only 1 mm is 10 mm). Will shift). In this case, in order to attach the cab to a predetermined set height, it is necessary to prepare a mount that incorporates a spring corresponding to a cab having a different weight depending on the model or specification, for example, a spring having the same spring constant but different free height. In a cab that is produced in a variety of small quantities, such as a work vehicle, the cost increases and component management becomes complicated. Normally, the cab is mounted by mounting mounts at the four corners of the cab to support the cab. However, if the center of gravity of the cab is shifted from the center, the load applied to each mount is different, so it is set to be soft. Due to the spring constant of the spring 48, the variation in the degree of sinking of each mount increases. Therefore, in order to mount the cab at a predetermined height with a predetermined flatness, it is necessary to prepare a mount that incorporates springs that can handle different loads depending on the location of the cab. In addition, parts management becomes complicated.
[0005]
The present invention has been made paying attention to the above problems, and even when a cab having a different weight is mounted, the cab can be attached to a predetermined set height, and corresponds to a cab for a variety of small-quantity production. It aims to provide a possible liquid-filled mount.
[0006]
[Means, actions and effects for solving the problems]
In order to achieve the above object, an elastic body, a stud penetrating the elastic body, a cylindrical shape having an opening on one end side and a bottom surface on the other end side, containing a viscous liquid therein, the one end side A case in which the viscous liquid is sealed by fitting the elastic body and the stud in an axial direction into the opening, and a damping member attached to the stud in a state of being immersed in the viscous liquid, and the damping In a liquid-filled mount provided with a load supporting spring disposed between a member and the bottom surface of the case, an axial position of a spring receiving member that supports one end of the spring from the bottom surface side of the case by changing the mounting load adjusting mechanism for adjusting the mounting load of the spring is provided, the mounting load adjustment mechanism, a tubular shape along the axial direction, and through the bottom surface to the bottom surface of the case A support member that is attached, a support shaft that is inserted into the support member so as to be movable in the axial direction and that can change the axial position of the spring support member, and the support member and the support A seal member that is provided between the shaft and seals the viscous liquid, and a mechanism that positions a relative position between the support member and the support shaft is provided .
[0007]
In other words, since the mounting load of the spring for supporting the load can be adjusted, the mounting load of this spring is adjusted corresponding to a cab having a different weight or a cab whose center of gravity is shifted from the center with one type of mount. As a result, the mounting height of each cab and the level of the cab can be adjusted to a predetermined set position, and the mounting cost can be reduced and the parts management can be facilitated.
Further, since the mounting load is adjusted by screwing, continuous and minute adjustment is possible.
[0008]

An annular gap is formed between the outer peripheral portion and the case 1. H1 is formed. In addition, a small hole 4a is provided on the bottom surface in order to allow the air accumulated below the damping member 4 to escape upward after sealing a viscous liquid described later.
A coil spring 8 is provided between the spring receiving member 9 and the damping member 4 disposed on the bottom of the case 1. The cup-shaped damping member 4 also has a function as a retainer for preventing the lateral displacement of the coil spring 8.
[0010]
An attachment load adjusting mechanism 10 that adjusts the attachment load of the coil spring 8 by adjusting the axial position of the spring receiving member 9 is provided at the center of the bottom surface of the case 1. The attachment load adjusting mechanism 10 includes a support member 11 that passes through the bottom surface of the case 1 and is fixed to the case 1, and a support shaft 12 that is screwed into the support member 11 to support the spring receiving member 9. As prepared.
The support member 11 has a cylindrical shape, and its upper end is fixed to the center of the bottom surface of the case 1 along the axial direction by means such as welding. A circumferential groove is provided on the inner surface of the upper end portion of the support member 11, and an O-ring 13 is attached to the groove. The support member 11 has a female screw threaded below the groove.
The support shaft 12 is a cylindrical member having a convex portion 12a at the center of the upper end and a hexagonal hole 12b at the center of the lower end, and a male screw is threaded on the outer peripheral surface below the center portion.
The spring receiving member 9 has an upper end surface 12c of the supporting shaft 12 in a state in which the convex portion 12a of the supporting shaft 12 screwed into the supporting member 11 is loosely inserted into a hole provided in the center of the spring receiving member 9. The support shaft 12 is supported by a lock nut 14 at a predetermined axial position.
[0011]
The stud 3 has a cylindrical shape having a screw hole 3a at the center of the upper end portion, and a detent pin 31 is attached to the upper end portion. The outer peripheral surface of the stud 3 is subjected to surface treatment such as molybdenum disulfide baking or hard chrome plating, or surface treatment for improving lubricity such as manganese phosphate coating treatment.
The sleeve 7 has a cylindrical shape and has two circumferential grooves on the inner surface of the upper end portion, and a scraper 7a is mounted on the upper groove and an oil seal 7b is mounted on the lower groove. The sleeve 7 is mounted with a dry bearing 7c such as a DU bush having an inner diameter in airtight contact with the stud 3 below the two grooves to hold the stud 3 slidably in the axial direction. The sleeve 7 and the cylindrical case 2 are joined to each other in a concentric position by a cylindrical elastic body 6. By inserting the elastic body 6 into the case 1, the sleeve 7 is inserted at the axial center position of the case 1 through the elastic body 6. The sleeve 7 is held so that the lower end thereof is in the vicinity of the step 1e. Thereby, the stud 3 is also held at the axial center position of the case 1 via the elastic body 6 and the sleeve 7.
[0012]
The cylindrical case 2 has a cylindrical portion 2a having a diameter smaller than the inner diameter of the case 1 and a mounting plate 2c provided with a mounting hole 2b. The mounting hole 1b of the mounting plate 1d of the case 1 and the mounting hole 2b of the mounting plate 2c of the cylindrical case 2 are in the same positional relationship when the elastic body 6 is inserted into the case 1 and assembled.
The cylindrical elastic body 6 is molded from rubber, resin, or the like and has a circumferential recess 6a on the lower surface. In the present embodiment, the recess 6a is formed in an annular shape in the circumferential direction. However, the present invention is not limited to this. For example, a plurality of (for example, two) recesses are provided discretely at positions facing the stud 3. Alternatively, concave portions may be provided at positions having different radii. Further, the elastic body 6 wraps and joins the sleeve 7 so that the lower end of the sleeve 7 protrudes slightly below the outer periphery of the lower surface, and inserts the damping plate 5 into the case 1 by pressing the damping plate 5 against the step 1 e of the case 1. Has been. Then, the claw 1c for fixing the case 1 is bent and caulked so as to wrap around the side surface of the mounting plate 2c of the cylindrical case 2, thereby fixing the cylindrical case 2 to the case 1 and completing the mounting of the elastic body 6. .
[0013]
The attenuation plate 5 attached to the step 1e portion of the case 1 has a disk shape having an outer diameter substantially the same as the inner diameter of the case 1 above the step 1e, and an elastic body that wraps the lower end portion of the sleeve 7 at the center thereof. A hole 5 a having a diameter slightly larger than the outer diameter of 6 is provided, and an annular gap H 2 is formed between the elastic body 6 at the lower end of the sleeve 7.
The case 1 sealed by the elastic body 6 is filled with a viscous liquid L such as silicon oil halfway through the recess 6a of the elastic body 6, and the upper portion of the recess 6a is sealed by the viscous liquid L. An air chamber is formed. The viscous liquid L is injected into the case 1 from the through hole of the support member 11 before the support shaft 12 is screwed into the support member 11.
With the above configuration, the inside of the case 1 is divided into the a chamber Sa, the b chamber Sb, and the c chamber Sc from below by the damping member 4 and the damping plate 5. The a chamber Sa and the b chamber Sb communicate with each other via the annular gap H1 and the small hole 4a, and the b chamber Sb and the c chamber Sc communicate with each other via the annular gap H2. The c chamber Sc includes the air chamber described above.
[0014]
FIG. 2 shows a state in which a set load is applied due to the mounting of the cab, and the stud 3 is sunk in a steady state position, and the upper end of the stud 3 is in a steady position P. Due to the load caused by vibration or impact, the stud 3 can be stroked within the range of the distance m1 upward from the steady position P and the distance m2 downward. The distance m1 is defined by the distance between the damping member 4 and the damping plate 5, and the distance m2 is defined by the upper end of the stud 3 and the upper surface of the elastic body 6.
FIG. 3 shows the state of the mount alone without mounting the cab, and the stud 3 is held by the coil spring 8 in a state where the damping member 4 abuts against the damping plate 5. The protruding amount m3 of the stud 3 from the upper surface of the elastic body 6 is m3 = m2 + m1. The holding load of the coil spring 8 in this state is the “mounting load”.
[0015]
In the mount alone, the support shaft 12 is screwed in until the distance T between the lower end surface of the support shaft 12 and the lower end surface of the support member 11 becomes a predetermined distance T0, and the mounting height N of the coil spring 8 becomes a predetermined value N0. By fixing the support shaft 12 with the nut 14, the assembly of the mount is completed in a state where the mounting load for a predetermined cab is set. If this mount is used for mounting a cab having a weight different from that of a predetermined cab, the stud 3 will shift from the steady position P in a steady state after mounting. Therefore, a deviation corresponding to the difference in weight is caused by any of the following. adjust.
(1) Obtain the screwing amount of the support shaft 12 corresponding to the difference in the mounting load adjustment weight of the mount alone (determined from the spring constant of the coil spring 8 and the screw pitch of the support shaft 12), and screw in the obtained amount. Adjust the mounting load with. In this case, the screwing amount may be seen from the distance T between the lower end surface of the support shaft 12 and the lower end surface of the support member 11, or the screwing amount may be seen from the rotation amount of the support shaft 12.
(2) Height adjustment after the cab is mounted After the cab is mounted on the body frame together with the cab, until the positional relationship between the body frame and the cab matches the design value (the distance between the upper end of the stud 3 and the upper surface of the elastic body 6 is a distance). Screw in the support shaft 12 until it matches m2.
[0016]
It should be noted that fine adjustment may be performed by "(2) Height adjustment after mounting the cab" after the rough adjustment of the mounting load is performed by "(1) Mounting load adjustment by mount alone".
“(2) Height adjustment after cab mounting” is performed by screwing the support shaft 12 while maintaining the positional relationship of the stud 3, the damping member 4, the coil spring 8, the spring receiving member 9 and the support shaft 12. Although the adjustment is to move in the axial direction, when the cab is separated from the mount, it is the same as the mounting height of the coil spring 8 in “(1) Adjusting the mounting load of the mount alone”. For this reason, “(2) Height adjustment after cab mounting” is substantially the same as adjusting the mounting load of the coil spring 8.
[0017]
According to the above configuration, the axial position of the spring receiving member 9 can be adjusted by the screwing position of the support shaft 12. For this reason, the mounting load of the coil spring 8 can be adjusted, and even if the weight of the cab differs depending on the model or specification, the mounting load can be changed according to the weight of the cab. It can be mounted at the mounting height (steady position P in FIG. 2). As a result, it is possible to obtain a liquid-filled mount that can be used for various types of cabs by a single type, thereby reducing costs and facilitating component management. In addition, even if the cab's center of gravity shifts from the center and the support load of each mount differs, the amount of sinking of each mount will vary and the level of the cab will not be secured. The mounting load can be changed accordingly, and the cab can be mounted horizontally. As a result, it is possible to obtain a liquid-filled mount that can handle one type of cab whose center of gravity is deviated from the center, thereby reducing costs and facilitating component management. Since screws are used for positioning the support shaft 12, continuous and minute adjustments are possible.
In addition, the mounting load can be adjusted while looking at the screwing amount of the support shaft 12 in the state of the mount alone before assembling the vehicle body, and the cab height position with respect to the vehicle body frame can be adjusted even when assembled with the cab together with the cab. By turning and adjusting the support shaft 12 while watching, the cab mounting height can be finely adjusted, the degree of freedom in the assembly process can be increased, and the mounting accuracy can be improved.
[0018]
Note that the present invention is not limited to the above-described embodiment, and it goes without saying that changes and modifications can be made within the scope of the present invention.
For example, as shown in FIG. 4, the welding position of the support member 11 with the case 1 may be moved to the lower side of the support member 11 so that the support member 11 protrudes inside the case 1. In this case, a columnar convex portion 16 a that avoids interference with the protruding support portion 11 is provided at the center portion of the spring receiving member 16. Thereby, the protrusion amount from the bottom face of case 1 becomes small, and a compact liquid enclosure mount can be obtained.
Further, as shown in FIG. 5, the spring receiving member 17 and the support shaft 18 may be fixed by a method such as welding or caulking.
[0019]
Although the example of positioning using the screws of the support member 11 and the support shaft 12 and fixing with the lock nut 14 has been described, the support shaft having no screw portion is inserted into the case to a predetermined position using a jack or the like. The support shaft may be fixed later. Examples of the fixing method include the following.
(1) As shown in FIG. 6, a radial screw hole is provided in the support member 21A, and the support shaft 22A is positioned and then fixed with a set screw 23.
(2) As shown in FIG. 7, the support member 21B is provided with a radial through hole g, the support shaft 22B is provided with a plurality of radial through holes h, and any of the through holes h of the support shaft 22B is provided. The pin 24 is inserted so as to coincide with the through hole g of the support member 21B, and the support shaft 22B is fixed. At this time, as shown in FIG. 7, by providing through holes h close to each other in the axial direction in mutually different radial directions, the axial pitch of the through holes h can be made fine, and fine adjustment can be accommodated. Become. Here, 25 is a split pin for preventing the pin 24 from coming off.
(3) As shown in FIG. 8, both ends of the shaft 26a provided at one end of the lever 26 are supported with play in the hole f provided in the bracket 28 on the support member 21C side, and the lever 26 The support shaft 22C is inserted into the support member 21C by loosely fitting into a hole 26b provided in the center. A pin 26 c is erected on the other end side of the lever 26, and guides a spring 27 disposed between the case 1 and the lever 26. In the direction in which the support shaft 22C is inserted into the case, the spring 27 contracts, so that it does not twist between the hole 26b and the support shaft 22C, but in the direction in which the support shaft 22C comes off, the support shaft 22C is bent. Can be fixed.
[0020]
Further, as shown in FIGS. 9 and 10, a plurality of attachment load adjusting mechanisms 10 may be provided at the bottom of the case 1 to position and support the spring receiving member 39. Thereby, even when the mounting load is large, the load applied to each screw portion can be dispersed to prevent the screw portion from being damaged and to reduce the screwing force at the time of screwing.
When the support shaft 12 is screwed, a hexagonal wrench may be inserted into the hexagonal hole 12b and screwed. Alternatively, the support shaft 12 may be screwed using a wrench or the like provided with a two-surface width at the lower end portion. I do not care.
In order to reduce the frictional resistance between the spring receiving member 9 and the support shaft 12 when the support shaft 12 is screwed, a resin washer may be interposed between the spring receiving member 9 and the support shaft 12. .
Further, although the example in which the O-ring 13 is mounted on the support member 11 side has been described, the O-ring 13 may be mounted with a groove provided on the outer periphery of the upper portion of the support shaft 12.
Furthermore, although the structure in which the support member 11 is fixed to the case 1 has been described, the support member may be configured by a part of the case.
[0021]
The stud 3 can be slid in the axial direction through the sleeve 7 penetrating the elastic body 6. However, if the mount is of a type provided with a spring that is arranged below the stud and receives an axial load. The mounting load adjusting mechanism 10 of the present invention can be applied.
For example, as shown in FIG. 11, the mounting load adjusting mechanism 10 may be applied to a liquid-filled mount of a type including an elastic body 36 that functions as a sealing lid and a vulcanized and bonded stud 33. The outer periphery of the elastic body 36 is vulcanized and bonded to the inner periphery of the cylindrical case 32 that is press-fitted into the opening of the case 31. The attenuation member 34 attached to the lower end of the stud 33 includes a metal core member 34a and an elastic member 34b that covers the core member 34a. The outer peripheral surface of the damping member 34 is slidably in contact with the inner peripheral surface of the cylindrical portion of the case 31, and at least one groove H 4 communicating with the inside of the case 31 partitioned by the damping member 34 is provided.
[0022]
The reason why the fixed damping plate 5 is provided in addition to the damping member 4 that moves integrally with the stud 3 is to obtain the following effects.
(1) The b chamber Sb can be brought into a state close to sealing, and even if the stud 3 receives an upward load, the b chamber Sb is subjected to a downward load. As with Sa, the pressure can be increased. As a result, a large differential pressure can be generated on both sides of the damping member 4, and a large damping force can be obtained in the gap H1 when the stud is moved upward as in the case where the stud is moved downward.
(2) Since a large differential pressure can be generated on both sides of the damping member 4, even when a large load in the upward direction acts on the stud 13, the b chamber Sb can be increased in pressure, corresponding to the load. Even if the differential pressure with respect to the a chamber Sa increases, the pressure in the a chamber Sa is not reduced to the extent that cavitation occurs in the a chamber Sa, and the occurrence of cavitation is prevented to prevent the viscous liquid L in the annular gap H1. By securing the flow, a large damping force can be obtained stably.
(3) In addition to the damping effect in the gap H1 in the above (1) and (2), the damping effect in the gap H2 is also obtained. Since these effects are not directly related to the object of the present invention, it goes without saying that the present invention can be applied to a mount in which the attenuation plate 5 is omitted.
In addition, although the cab is taken as an example of the mounted member, the mounted member may be applied to a mounted member for the purpose of reducing vibration and impact other than the cab.
[0023]
As described above, according to the present invention, the mounting load of the spring that supports the load in the axial direction can be adjusted. Therefore, the mounting load of the spring can be adjusted to the weight of each cab even for cabs having different weights. By setting to a value corresponding to, the cab mounting height can be adjusted to a predetermined setting position. Therefore, one type of mount can be used for various types of cabs, and the cost of the mount can be reduced and the parts management can be facilitated. In addition, even if the cab's center of gravity shifts from the center and the support load of each mount is different, and the level of the cab cannot be secured, it can be changed to a mounting load according to the support load of each mount. Can be mounted horizontally. Accordingly, it is possible to cope with a cab whose center of gravity is deviated from the center with one type of mount, and the cost can be reduced and component management is facilitated.
