Description

Technical Field

[0001] The invention relates to the field of agricultural machinery, and in particular to a connecting device between an axle and a wheel rim. Background Art

[0002] At present, the wheels and axles of general vehicles are directly connected together. In agricultural machinery, due to the particularity of its working environment, there are often special requirements for wheelbase, requiring that the tires should not damage crops during the process of traveling. In order to ensure the requirements of wheelbase, a half-axle retractable axle is generally selected. However, when the half-axle retractable axle does not meet the use requirements due to load-bearing and other reasons, a half-axle non-retractable axle is used. If the axle length is small and there is no axle with a suitable length, in order to obtain a larger wheelbase, if the wheel is connected to the axle, the eccentricity of the rim spoke plate will be increased, and the eccentricity of the rim spoke plate will increase, which is not conducive to the load-bearing performance of the rim. At this time, a special device is required to connect the wheel and the axle to achieve the purpose of reducing the eccentricity of the rim spoke plate while obtaining the wheelbase that meets the requirements. However, the rim mounting bolts on the axle are currently close to the wheel hub, and the use of a connector with a thin wall thickness has poor load-bearing performance and cannot meet the use requirements of agricultural machinery. The use of a connector with a wall thickness that meets the requirements will interfere with the wheel hub and cannot be installed. Summary of the invention

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] according to Figure 1-3 , the present invention provides a technical solution:

[0025] A vehicle bridge and wheel rim connection device, comprising an adapter flange 1 and a connector 2, wherein the adapter flange 1 is configured as a circular boss structure, and the adapter flange 1 is sequentially provided with a flange positioning hole 16, a flange inner connecting hole 12, and a flange outer connecting hole 13 from the center position to the periphery, wherein the flange positioning hole 16, the flange inner connecting hole 12, and the flange outer connecting hole 13 are all through holes, and the flange positioning hole 16 is coaxial with the adapter flange 1, and a flange boss 14 is fixedly provided on the right end surface 15 of the adapter flange 1 extending to the right, and the flange boss 14 is coaxial with the adapter flange 1, and the connector 2 is configured as a circular boss structure, and the connector 2 is sequentially provided with connecting holes from the center position to the periphery. The connector 2 has a rim positioning hole 43 and a connector outer connecting hole 25, and an annular cylinder 21 and a connector boss 27 are fixedly arranged in sequence on the second end face 23 of the connector 2 extending to the right. The annular cylinder 21 and the connector boss 27 are arranged as an integral structure, and the connector boss 27 is coaxial with the annular cylinder 21. The connector 2 radially positions the rim positioning hole 43 on the connector 2 through the connector boss 27 to ensure that the rim 4 and the connector 2 run coaxially. A connector inner connecting hole 26 is fixedly arranged on the right top end of the annular cylinder 21 extending to the periphery. The connector 2 is radially positioned with the flange boss 14 through the connector positioning hole 24 to ensure that the connector 2 is coaxial with the adapter flange 1.

[0026] The flange positioning hole 16 is arranged at the center of the adapter flange 1. The aperture size of the flange positioning hole 16 is the same as the axial diameter of the wheel hub 33. The adapter flange 1 is radially positioned through the flange positioning hole 16 to ensure that the adapter flange 1 is coaxial with the wheel hub 33 of the axle 3, so that the adapter flange 1 rotates smoothly when the axle moves.

[0027] A group of flange inner connecting holes 12 and a group of flange outer connecting holes 13 are evenly distributed on the left end face 11 of the adapter flange 1. The pitch circles of the flange inner connecting holes 12 and the flange outer connecting holes 13 are concentric and the center of the pitch circle is located on the axis of the adapter flange 1. The mounting bolts 31 pass through the flange inner connecting holes 12 to assemble the left end face 11 to the axle flange end face 32, so that the flange positioning holes 16 cooperate with the wheel hub 33 of the axle 3. The load on the axle 3 is transferred to the adapter flange 1 through the wheel hub 33 and the flange positioning holes 16, preventing the bolts passing through the flange inner connecting holes 12 from being damaged by shear force.

[0028] The connector positioning hole 24 is set at the center of the connector 2. The diameter of the connector positioning hole 24 is the same as the outer diameter of the flange boss 14. The connector 2 is radially positioned with the flange boss 14 through the connector positioning hole 24 to ensure that the connector 2 and the adapter flange 1 run coaxially.

[0029] A set of connector outer connecting holes 25 are evenly distributed on the first end face 22 of the connector 2. Bolts pass through the connector outer connecting holes 25 and the flange outer connecting holes 13 to assemble the first end face 22 to the right end face 15, so that the connector positioning holes 24 cooperate with the flange boss 14. The load on the adapter flange 1 is transferred to the connector 2 through the flange boss 14 and the connector positioning holes 24, preventing the bolts passing through the connector outer connecting holes 25 and the flange outer connecting holes 13 from being damaged by shear force.

[0030] A group of connector inner connecting holes 26 are evenly distributed on the third end face 28 of the connector 2. Bolts pass through the connector inner connecting holes 26 and the rim mounting holes 41 to assemble the spoke end face 42 to the third end face 28, so that the connector boss 27 and the rim positioning hole 43 cooperate. The load on the connector 2 is transferred to the rim through the connector boss 27 and the rim positioning hole 43, preventing the bolts passing through the connector inner connecting holes 26 and the rim mounting holes 41 from being damaged by shear force, and even distribution ensures force balance.

[0031] The thickness and length of the annular column 21 can be set according to design requirements, so that the wheelbase that meets the use requirements is obtained while having sufficient load-bearing capacity.

[0032] The first end surface 22 and the third end surface 28 are parallel to each other and perpendicular to the annular column 21 , and the connector positioning hole 24 is perpendicular to the annular column 21 .

[0033] The dividing circles where the connector outer connecting hole 25 and the connector inner connecting hole 26 are located are concentric, and the center of the dividing circle is located on the axis of the annular cylinder 21 .

[0034] The pitch circle diameter of the connector outer connecting hole 25 is larger than the diameter of the third end face 28, the diameter of the flange boss 14 is slightly smaller than the diameter of the connector positioning hole 24, the flange boss 14 and the connector positioning hole 24 are clearance-fitted, the pitch circle diameter of the flange outer connecting hole 13 is equal to the pitch circle diameter of the connector outer connecting hole 25, and the distance from the right end face 15 to the flange boss end face 17 is smaller than the distance from the first end face 22 to the second end face 23.

[0035] When implementing the axle and rim connection device described in the present invention, the adapter flange 1 is positioned on the axis of the axle hub through the flange positioning hole 16 to ensure that the adapter flange 1 is coaxial with the axle hub. At this time, the load on the axle 3 is transferred to the adapter flange 1 through the axle hub 33 and the flange positioning hole 16. A group of connector outer connecting holes 25 are evenly distributed on the first end face 22. Bolts pass through the connector outer connecting holes 25 and the flange outer connecting holes 13 to assemble the first end face 22 to the right end face 15. At this time, the load on the adapter flange 1 is transferred to the connector 2 through the flange boss 14 and the connector positioning hole 24; the rim 4 is radially positioned on the connector 2 through the connector boss 27 and the rim positioning hole 43 to ensure that the rim and the connector 2 are coaxial. A group of connector inner connecting holes 26 are evenly distributed on the third end face 28 of the connector 2. Bolts pass through the connector inner connecting holes 26 and the rim mounting holes 41 to assemble the spoke end face 42 to the third end face 28. At this time, the load on the connector 2 is transferred to the rim 2 through the connector boss 27 and the rim positioning hole 43. If the length of the annular column 21 of the connector 2 is lengthened or shortened, the spoke plate of the rim 4 does not need to be eccentric, which is more conducive to the load-bearing capacity of the rim 4.

[0036] In the axle and rim connection device of the present invention, the adapter flange and the connector adopt a positioning mechanism in which the boss and the positioning hole are nested with each other, thereby achieving accurate positioning while increasing the load-bearing capacity; the use of bolt connection greatly reduces the difficulty of assembly and disassembly.
