Description

Technical Field

[0001] The utility model relates to the technical field of mining dump trucks, in particular to a buffer component mounting support, a buffer vibration reduction component and a leaf spring suspension. Background Art

[0002] The existing front suspension structures of mining dump trucks can be divided into two types: one is a suspension cylinder structure, which uses a gas spring for buffering and shock absorption, and cooperates with multiple connecting rods to bear longitudinal and lateral forces; the other is a leaf spring structure, which uses leaf springs and leaf spring supports installed on the frame to bear gravity, longitudinal force and lateral force.

[0003] In the prior art, leaf spring structures are widely used, and there are two main layout structures: one is that both ends of the leaf spring have ear structures, and the ear structures at both ends are connected to the leaf spring support, and the leaf spring support is fixed to the frame longitudinal beam. The other is that both ends of the leaf spring are slidably matched with the leaf spring support. Generally, in order to achieve the effect of buffering and reducing vibration under heavy load conditions and avoid hard collision between the frame longitudinal beam and the leaf spring, a buffering and reducing vibration component is usually set between the two.

[0004] The buffer vibration reduction assembly includes a buffer mounting bracket and a buffer mounted on the buffer mounting bracket. The buffer is arranged facing the leaf spring, and the buffer mounting bracket is fixed to the side of the frame longitudinal beam by fasteners. When the vehicle load is large, the longitudinal impact load is large when the vehicle passes through a bumpy road, which usually causes the buffer mounting bracket to deform or tear.

[0005] Therefore, how to improve the reliability of the buffer component mounting bracket and reduce the risk of deformation or tearing when subjected to a large impact load is a technical problem that technical personnel in this field currently need to solve. Utility Model Content

[0043] The core of the utility model is to provide a buffer component mounting support, so as to improve the reliability of the buffer component mounting support and reduce the risk of deformation or tearing when subjected to a large impact load;

[0044] Another core of the utility model is to provide a buffer vibration reduction assembly and a leaf spring suspension with the buffer component mounting support.

[0045] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0046] like Figure 1 and Figure 2As shown, the embodiment of the utility model discloses a buffer component mounting bracket 110, which is used to install a buffer component 120 and provide a mounting base and support for the buffer component 120, so that the buffer component 120 can be installed on the frame longitudinal beam 200 through the buffer component mounting bracket 110.

[0047] The buffer component mounting support 110 disclosed in the embodiment of the utility model comprises a buffer component mounting plate 113, a longitudinal beam mounting plate 111 and a reinforcing connecting plate 112. The buffer component mounting plate 113 is used to mount a buffer component 120. Specifically, the buffer component mounting plate 113 is a plate-shaped structure having a first side surface and a second side surface opposite to each other. The buffer component 120 is mounted on the first side surface of the buffer component mounting plate 113. In a normal working state, the first side surface of the buffer component mounting plate 113 is a lower surface, and the second side surface of the buffer component mounting plate 113 is an upper surface.

[0048] The longitudinal beam mounting plate 111 has a longitudinal beam side mounting wall 1112 for being attached to the side of the frame longitudinal beam 200 and a longitudinal beam bottom mounting wall 1113 for being attached to the bottom of the frame longitudinal beam 200. It can be seen that in this embodiment, the longitudinal beam mounting plate 111 is different from the longitudinal beam mounting plate in the prior art, and it is attached to at least the side and bottom of the frame longitudinal beam 200.

[0049] The longitudinal beam side mounting wall 1112 is provided with fastening holes 1111 for installing fasteners. The number, position and arrangement of the fastening holes 1111 can be designed by those skilled in the art according to requirements so as to meet the requirements of installation and bear impact loads.

[0050] The reinforcing connecting plate 112 is connected to the buffer mounting plate 113 and the longitudinal beam mounting plate 111 respectively, so as to realize the connection between the buffer mounting plate 113 and the longitudinal beam mounting plate 111. It should be noted that the reinforcing connecting plate 112 is connected to the second side surface of the buffer mounting plate 113.

[0051] The buffer component mounting bracket 110 disclosed in the embodiment of the utility model, after being mounted to the frame longitudinal beam 200, the side of the longitudinal beam mounting plate 111 (i.e., the longitudinal beam side mounting wall 1112) is connected to the side of the frame longitudinal beam 200 through the fastener passing through the fastening hole 1111, and the bottom of the longitudinal beam mounting plate 111 (i.e., the longitudinal beam bottom mounting wall 1113) contacts the bottom of the frame longitudinal beam 200. When the vehicle bounces up and down and the leaf spring contacts the buffer component, the impact force is buffered by the buffer component and then transmitted to the side and bottom of the frame longitudinal beam 200 through the longitudinal beam side mounting wall 1112 and the longitudinal beam bottom mounting wall 1113. On the basis of the prior art, the utility model adds the bottom support of the frame longitudinal beam 200. Compared with the side support of the frame longitudinal beam 200 alone, the force is more reasonable, the reliability of the buffer component mounting bracket 110 is improved, and the risk of deformation or tearing is reduced.

[0052] In this embodiment, the longitudinal beam side mounting wall 1112 and the longitudinal beam bottom mounting wall 1113 are connected as an integrated structure, and the longitudinal beam side mounting wall 1112 and the longitudinal beam bottom mounting wall 1113 are perpendicular to each other. The longitudinal beam side mounting wall 1112 and the longitudinal beam bottom mounting wall 1113 are connected as an integrated structure, which can be directly bent into a plate by a bending process. Figure 6 The shape shown can also be connected by two plates to form a vertical longitudinal beam side mounting wall 1112 and a longitudinal beam bottom mounting wall 1113, wherein the connection method is not limited to welding, fastener connection, etc.

[0053] In order to reduce the stress concentration generated at the connection part between the longitudinal beam side mounting wall 1112 and the longitudinal beam bottom mounting wall 1113, in this embodiment, the longitudinal beam side mounting wall 1112 and the longitudinal beam bottom mounting wall 1113 are transitionally connected through a transition plate 1114, and the transition plate 1114 is an arc-shaped plate. That is, in this embodiment, the longitudinal beam side mounting wall 1112 gradually transitions to the longitudinal beam bottom mounting wall 1113 through the arc-shaped transition plate 1114, so as to avoid the formation of a sharp angle between the two, and to avoid the fracture at the sharp angle when subjected to a large impact.

[0054] like Figure 3 As shown, for the convenience of processing, the longitudinal beam side mounting wall 1112 and the longitudinal beam bottom mounting wall 1113 can both be rectangular. For the convenience of understanding, the dimension along the extension direction of the frame longitudinal beam 200 is defined as the extension direction dimension, and the dimension in the other direction (i.e., the direction in which the longitudinal beam side mounting wall 1112 and the longitudinal beam bottom mounting wall 1113 are perpendicular to the extension direction of the frame longitudinal beam 200) is defined as the extension direction dimension. That is, the extension direction of the longitudinal beam side mounting wall 1112 can be understood as the direction extending outward in the vertical direction; the extension direction of the longitudinal beam bottom mounting wall 1113 can be understood as the direction extending outward in the horizontal direction.

[0055] The extension direction dimension of the longitudinal beam side mounting wall 1112 is equal to the extension direction dimension of the longitudinal beam bottom mounting wall 1113 , that is, the longitudinal beam mounting plate 111 can be formed by bending a rectangular plate to form the longitudinal beam side mounting wall 1112 and the longitudinal beam bottom mounting wall 1113 .

[0056] The extension direction dimension of the longitudinal beam side mounting wall 1112 is greater than the extension direction dimension of the longitudinal beam bottom mounting wall 1113, that is, when bending, a larger area is reserved for the longitudinal beam side mounting wall 1112. The longitudinal beam side mounting wall 1112 and the longitudinal beam bottom mounting wall 1113 are both rectangular plates, and without considering the thickness dimension, they have two dimensions, such as the width and length of the plate. The extension direction dimension of the longitudinal beam side mounting wall 1112 and the longitudinal beam bottom mounting wall 1113 may be a width dimension or a length dimension.

[0057] like Figure 3As shown, the extension direction of the longitudinal beam side mounting wall 1112 is the length direction, and its extension direction is the width direction; correspondingly, the extension direction of the longitudinal beam bottom mounting wall 1113 is the length direction, and its extension direction is also the width direction. It should be noted that if the dimension of the longitudinal beam side mounting wall 1112 along the extension direction is greater than the dimension along the extension direction, the extension direction of the longitudinal beam side mounting wall 1112 is the width direction, and its extension direction is the length direction.

[0058] In this embodiment, since the longitudinal beam side mounting wall 1112 also takes into account the fastening function with the frame longitudinal beam 200, the dimension of the longitudinal beam side mounting wall 1112 in the extension direction needs to be designed to be larger to facilitate the arrangement of multiple fastening points; and the longitudinal beam bottom mounting wall 1113 only needs to provide supporting force, as long as the force transmission can be achieved, its dimension in the extension direction does not need to be designed to be larger.

[0059] like Figure 6 As shown, in a specific embodiment of the utility model, the buffer mounting plate 113 is parallel to the longitudinal beam bottom mounting wall 1113 and is arranged at intervals. The distance between the buffer mounting plate 113 and the longitudinal beam bottom mounting wall 1113 is controlled by reinforcing the connecting plate 112. Since the frame longitudinal beam 200 and the leaf spring 300 are staggered in the vertical direction, the buffer mounting plate 113 and the longitudinal beam mounting plate 111 are designed as two parts, and the connection between the two is achieved by reinforcing the connecting plate 112, so that the buffer mounting plate 113 can have a larger area to facilitate the arrangement of the buffer 120, while the longitudinal beam bottom mounting wall 1113 only needs to transmit the impact force and does not need to be designed with a larger area. In addition, the buffer mounting plate 113 is separated from the longitudinal beam bottom mounting wall 1113 by a distance, so that the reinforcing connecting plate 112 can have a larger contact area with the buffer mounting plate 113 and the longitudinal beam bottom mounting wall 1113, respectively, so as to improve the reliability of the connection and also facilitate the transmission of force.

[0060] The reinforcing connecting plate 112 has a connecting and fitting surface that fits on the longitudinal beam side mounting wall 1112 and the longitudinal beam bottom mounting wall 1113, and the connecting and fitting surface fits on the side of the longitudinal beam side mounting wall 1112 and the longitudinal beam bottom mounting wall 1113 that are not facing the frame longitudinal beam 200. That is, in this embodiment, the surface of the reinforcing connecting plate 112 facing the longitudinal beam mounting plate 111 matches the shape of the longitudinal beam mounting plate 111, so that the connecting and fitting surface can fit on the longitudinal beam side mounting wall 1112 and the longitudinal beam bottom mounting wall 1113. In this way, the contact area between the reinforcing connecting plate 112 and the longitudinal beam mounting plate 111 can be increased, and the stability of the connection can be improved.

[0061] In this embodiment, the width of the reinforcing connecting plate 112 gradually increases from away from the buffer mounting plate 113 to close to the buffer mounting plate 113. Since the buffer mounting plate 113 is the main force-bearing part, the width of the reinforcing connecting plate 112 facing the buffer mounting plate 113 is larger, and other parts do not need such a large width to reduce the overall weight.

[0062] like Figure 4 As shown, there are two reinforcing connecting plates 112, and they are respectively connected to the two side edges of the longitudinal beam mounting plate 111. A supporting rib 114 is provided between the two reinforcing connecting plates 112, and the supporting rib 114 is respectively connected to the longitudinal beam mounting plate 111 and the buffer component mounting plate 113. The supporting rib 114 may or may not be provided, and the volume of the supporting rib 114 is smaller than the volume of the reinforcing connecting plate 112. The number of the supporting rib 114 can be adjusted according to demand, and may be provided with one, multiple, or no supporting rib 114.

[0063] like Figure 1 and Figure 2 As shown, the embodiment of the utility model further discloses a buffer vibration reduction assembly 100, which includes a buffer component mounting support 110 and a buffer component 120. The buffer component mounting support 110 is the buffer component mounting support 110 disclosed in the above embodiment, and the buffer component 120 is installed on the buffer component mounting plate 113. The buffer component 120 can be a buffer rubber pad, which can be fixed on the buffer component mounting plate 113 by fasteners, so that the buffer component 120 can be replaced. Long-term contact between the leaf spring and the buffer component 120 can easily damage the buffer component 120 and lose the buffering effect. Since the buffer component 120 is installed by fasteners, it is easier to disassemble and convenient to replace the buffer component 120. The buffer vibration reduction assembly 100 disclosed in the embodiment of the utility model has all the technical effects of the above-mentioned buffer component mounting support 110, which will not be repeated herein.

[0064] like Figure 7 As shown, the embodiment of the utility model further discloses a leaf spring suspension, which includes a leaf spring 300, a frame longitudinal beam 200, and a buffer vibration reduction assembly 100 arranged on the frame longitudinal beam 200. The buffer vibration reduction assembly 100 is the buffer vibration reduction assembly 100 disclosed in the above embodiment, and the buffer 120 of the buffer vibration reduction assembly 100 is arranged facing the leaf spring 300. The leaf spring suspension disclosed in the embodiment of the utility model has all the technical effects of the above buffer vibration reduction assembly 100, which will not be repeated herein.

[0065] It should be noted that the leaf spring suspension should also include a front axle 400 and a shock absorber assembly 500. The middle part of the leaf spring 300 is arranged on the front axle 400, and the two ends are connected to the frame longitudinal beam 200. Under the support of the leaf spring 300, the frame longitudinal beam 200 is erected above the front axle 400. When the vehicle is on a bumpy road, the leaf spring 300 can filter out some vibrations to ensure comfort when driving on a bumpy road.

[0066] The shock absorber assembly 500 may include a shock absorber and a shock absorber support, wherein the first end of the shock absorber is hinged to the shock absorber support, and the shock absorber support is mounted on the frame rail 200. Since the shock absorber bears the impact of the vehicle, the shock absorber support and the connection between the shock absorber support and the shock absorber are prone to breakage, deformation and other problems. In order to facilitate replacement of the shock absorber support after deformation or breakage, in this embodiment, the shock absorber support can be mounted on the frame rail by a fastener. The leaf spring 300 is formed with a shock absorber ear, and the second end of the shock absorber is hinged to the shock absorber ear.

[0067] The leaf spring suspension may further include a steering cylinder assembly 600, which may include a steering cylinder and a steering cylinder support mounted on the frame longitudinal beam, one end of the steering cylinder being hinged to the steering cylinder support, and the other end being hinged to the steering arm on the front axle 400. Two steering cylinder assemblies 600 are symmetrically arranged, one on each of the left and right sides of the front axle 400, to assist the vehicle in steering.

[0068] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0069] As shown in this application and claims, unless the context clearly indicates an exception, the words "a", "an", "a kind" and / or "the" do not refer to the singular, but also include the plural. Generally speaking, the terms "include" and "comprise" only indicate the inclusion of clearly identified steps and elements, and these steps and elements do not constitute an exclusive list. The method or device may also include other steps or elements. The elements defined by the sentence "includes a..." do not exclude the existence of other identical elements in the process, method, commodity or device that includes the elements.

[0070] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

The above examples are only used to help understand the core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
