Detailed Implementation

[0029] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments and specific features in the embodiments are detailed descriptions of the technical solution of the present application, rather than limitations thereof. In the absence of conflict, the embodiments and technical features in the embodiments can be combined with each other.

[0030] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0031] Example 1:

[0032] like Figure 1 As shown, this embodiment provides a vibratory wheel, including a vibratory wheel body 2, a first support 1, and a second support 3. The vibratory wheel body 2 includes a wheel body 2-1. The first support 1 and the second support 3 are installed at both ends of the vibratory wheel body 2 along the rotation axis of the wheel body 2-1. The vibratory wheel body 2 is fixedly connected to the vehicle body through the first support 1 and the second support 3. The distance of the first support 1 from the ground does not exceed the diameter of the wheel body 2-1. The diameter of the wheel body 2-1 does not exceed 560 mm.

[0033] The first support 1 is connected to the vehicle body via the non-vibration side bolt group 5, and the second support 3 is connected to the vehicle body via the vibration side bolt group 4. The connection point between the first support 1 and the vehicle body is located inside the plane containing the two end faces of the wheel body 2-1. The ground clearance of any part of the first support 1 protruding outside the plane containing the end face of the wheel body 2-1 does not exceed the wheel body height (i.e., wheel body diameter). The second support 3 is connected to the vehicle body via the vibration side bolt group 4. The connection point between the second support 3 and the vehicle body is located above the wheel body 2-1. The ground clearance of any part of the second support 3 protruding outside the plane containing the end face of the wheel body 2-1 exceeds the radius of the wheel body 2-1.

[0034] Figure 2 yes Figure 1 Top view, such as Figure 2 As shown, the first support 1 has a central recessed structure, and the recessed position is used to avoid the wheel 2-1.

[0035] Figure 3 yes Figure 1 The right view, as shown Figure 3 As shown, the vibration side bolt group 4 connecting the second support 3 and the vehicle body is symmetrically arranged on both sides of a plane passing through the rotation axis of the wheel body 2-1 and perpendicular to the ground.

[0036] Figure 4 yes Figure 3 AA cross-section diagram, such as Figure 4 As shown, the vibratory wheel body 2 also includes a non-vibration side damper assembly 2-2, a non-vibration side travel bearing assembly 2-3, a non-vibration side bearing 2-4, an exciter 2-5, a vibration side bearing 2-6, a vibration side travel bearing assembly 2-7, a vibration side damper assembly 2-8, a spline sleeve 2-9, a vibration motor 2-10, a first bolt assembly 2-11, and a second bolt assembly 2-12. The first support 1, the non-vibration side damper assembly 2-2, the non-vibration side travel bearing assembly 2-3, the wheel body 2-1, the vibration side travel bearing assembly 2-7, the vibration side damper assembly 2-8, and the second support 3 are connected in sequence.

[0037] The non-vibration side travel bearing assembly 2-3 is fixed to the wheel body 2-1 by the second bolt group 2-12, and the vibration side travel bearing assembly 2-7 is fixed to the wheel body 2-1 by the first bolt group 2-11. The vibration motor 2-10 is installed at one end of the vibration side travel bearing assembly 2-7; the exciter 2-5 is supported on the non-vibration side travel bearing assembly 2-3 and the vibration side travel bearing assembly 2-7 by the non-vibration side bearing 2-4 and the vibration side bearing 2-6; the spline sleeve 2-9 is installed on the vibration motor 2-10 and is used to drive the exciter 2-5 to rotate around the axis together with the vibration motor 2-10 to generate centrifugal force, forcing the components such as the wheel body 2-1 installed in the non-vibration side damper group 2-2 and the vibration side damper group 2-8 to vibrate.

[0038] like Figure 5 and Figure 6 As shown, the vibration-side traveling bearing assembly 2-7 includes a coaxially arranged outer bearing housing 2-7-1, a traveling bearing housing 2-7-2, a motor connecting plate 2-7-3, a pressure plate 2-7-4, a double-row tapered roller bearing 2-7-5, and an oil seal 2-7-6. The pressure plate 2-7-4 is fixedly connected to the outer bearing housing 2-7-1 by bolts 2-7-7, and the motor connecting plate 2-7-3 is fixedly connected to the traveling bearing housing 2-7-2 by bolts 2-7-7. Through this installation, the outer bearing housing 2-7-1 can rotate relative to the traveling bearing housing 2-7-2.

[0039] The outer bearing housing 2-7-1 is provided with a group of open holes 2-7-8 for installing the first bolt group 2-11; the travel bearing housing 2-7-2 is provided with a circular hole 2-7-9 and a semi-circular hole 2-7-10 symmetrical with respect to the axis at a position corresponding to the group of open holes 2-7-8; the travel bearing housing 2-7-2 is provided with a threaded hole 2-7-11 for installing the vibration damper group 2-8.

[0040] It should be noted that the structure of the vibrating wheel body 2 is not completely fixed. The structure of the vibrating wheel body 2 described above is a vibrating wheel body 2 without a drive. A drive can also be installed on the vibrating wheel body 2.

[0041] By adopting the above-mentioned structure of the walking bearing seat 2-7-2, the first bolt group 2-11 connecting the outer bearing seat 2-7-1 and the wheel body 2-1 can be installed through the circular hole 2-7-9 and the semi-circular hole 2-7-10 on the walking bearing seat 2-7-2 that are symmetrical about the axis. This reduces the difficulty of radial arrangement inside the vibrating wheel and reduces the diameter of the vibrating wheel body 2-1.

[0042] By adopting the above-mentioned structure of the travel bearing housing 2-7-2, the vibration side damper assembly 2-8 can be directly mounted on the travel bearing housing 2-7-2 without the need for a damper mounting plate, thus simplifying the structure of the travel bearing assembly.

[0043] Figure 7 yes Figure 4 A schematic diagram of the structure of the first support 1 is shown below. Figure 7 As shown, the first support 1 includes a rectangular plate 1-1, a first connecting plate 1-2, a first side plate 1-3, a first annular plate 1-4, and a first chopped ring 1-5. The rectangular plate 1-1 at one end of the first support 1 has four holes for installing the non-vibration side bolt assembly 5 connected to the vehicle body. The first chopped ring 1-5 at the other end has four holes for connecting the non-vibration side shock absorber assembly 2-2 in the vibrating wheel body 2. The first support 1 has a centrally recessed structure. The first side plate 1-3 is fixedly connected to the first annular plate 1-4 and the first connecting plate 1-2, forming a centrally recessed area between the first annular plate 1-4 and the first connecting plate 1-2 to avoid the wheel body 2-1. The rectangular plate 1-1 is fixedly connected to the first connecting plate 1-2 on one side and to the vehicle body on the other side. The first chopped ring 1-5 is connected to the end of the first annular plate 1-4 away from the first side plate 1-3.

[0044] It should be noted that the lower parts of the first cut-edge ring 1-5, the first annular plate 1-4 and the first side plate 1-3 are all provided with cut edges, which are used to increase the gap between the lower part of the first support 1 and the wheel body 2-1, so that the lower part of the first support 1 and the wheel body 2-1 have a larger gap than the upper part of the first support 1 and the wheel body 2-1, which is conducive to the discharge of foreign objects.

[0045] Figure 8 yes Figure 4 A schematic diagram of the structure of the second support 3 is shown below. Figure 8 As shown, the second support 3 includes a welded and fixed second side plate 3-1, a second annular plate 3-2, and a second chopped ring 3-3. The upper part of the second side plate 3-1 has six holes for installing the vibration-side bolt assembly 4 connected to the vehicle body. One end of the lower part of the second chopped ring 3-3 has a hole for installing the vibration-side damper assembly 2-8 in the vibration wheel body 2. The lower part of the second chopped ring 3-3 has chopped edges to increase the gap between the lower part of the second support 3 and the wheel body 2-1, creating a larger gap between the lower part of the second support 3 and the wheel body 2-1 compared to the upper part, facilitating the discharge of foreign objects.

[0046] It should be noted that the distance from the ground of any part of the second annular plate 3-2 protruding outside the plane of the end face of the wheel body 2-1 exceeds the radius of the wheel body 2-1, and the distance from the ground of any part of the second side plate 3-1 also exceeds the radius of the wheel body 2-1. The larger distance from the ground of the parts protruding outside the plane of the end face of the wheel body 2-1 can compact the ground area with higher obstacles such as higher curb stones on the side.

[0047] Working principle: During use, the compaction functions on both sides of the vibrating wheel are separated. The wheel body 2-1 on the side where the first support 1 is located can extend into the concave side to compact the ground area under the concave side. The wheel body 2-1 on the side where the second support 3 is located can compact the ground area with higher obstacles on the side.

[0048] Example 2:

[0049] like Figure 9 As shown, this embodiment provides a vibratory roller, which is a lightweight self-propelled vibratory roller equipped with a vibratory wheel as provided in Embodiment 1. This vibratory roller includes a first vibratory wheel 61, a vehicle body 62, a cover 63, a control system 64, a conventional vibratory wheel 65, and a power and hydraulic system 66. The front wheel of the vibratory roller is the first vibratory wheel 61, which is the vibratory wheel provided in Embodiment 1, with one side of the wheel body protruding from the vehicle body. The rear wheel of the vibratory roller is a conventional vibratory wheel 85, which is a vibratory wheel in the prior art.

[0050] Figure 10 yes Figure 9 A schematic diagram of the application of a medium-light self-propelled vibratory roller shows that when encountering a ground area located on the side of a depression, the first vibratory wheel 61 of the vibratory roller is inserted into the depression on the side of the depression 71 to compact the ground area 72 below the depression.

[0051] In summary, the vibratory roller and vibratory road roller provided by this invention separate the compaction functions of the two sides of the vibratory roller by protruding the vehicle body on one side. The wheel body 2-1 on the side where the first support 1 is located can extend into the recessed side to compact the ground area below the recessed side. The part of the wheel body 2-1 on the side where the second support 3 is located, which protrudes from the plane outside the end face of the wheel body 2-1, has a larger distance from the ground and can compact ground areas with higher obstacles such as higher curb stones on the side. The semi-circular holes 2-7-10 symmetrical with respect to the axis are provided on the traveling bearing seat 2-7-2 in the vibratory roller body 2, which facilitates the bolt assembly between the outer bearing seat 2-7-1 and the rolling wheel body 2-1, reduces the difficulty of radial arrangement within the vibratory roller, and reduces the diameter of the vibratory roller body 2-1, making it easier to extend into narrow recessed sides. The vibratory road roller equipped with this vibratory roller can adapt to compacting ground areas within recessed sides as well as ground areas with higher obstacles such as higher curb stones on the side, thus expanding the applicability of the road roller.

[0052] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
