Description

Technical Field

[0001] This utility model belongs to the field of load-bearing technology of agricultural machinery, and in particular, it is an agricultural vehicle axle. Background Technology

[0002] Agricultural axles, also known as vehicle axles, are an important component of agricultural machinery (such as tractors and harvesters). They are connected to the vehicle frame or monocoque body via suspension, and wheels are installed at both ends. The main function of agricultural axles is to bear the load of agricultural machinery and maintain its normal travel on field roads. At the same time, agricultural axles also involve steering and driving functions.

[0003] Agricultural vehicle axles mainly consist of axle housing, main reducer, differential, half shafts, and wheel hubs. The axle housing is the mounting base for the axle, while the main reducer and differential are responsible for transmitting and distributing power. The half shafts transmit the torque output by the differential to the wheel hubs, driving the wheels to rotate.

[0004] While existing technologies such as Chinese invention patent application publication CN109532475A, Chinese utility model patent announcement CN206841082U, and Chinese utility model patent announcement CN207416444U all disclose agricultural vehicle axles, these axles have certain limitations in meeting the stability and load-bearing requirements of agricultural machinery. Load-bearing capacity is a crucial technical indicator for agricultural vehicle axles, determining the maximum load they can support. Therefore, it is necessary to improve existing axle technology to enhance its performance. Utility Model Content

[0027] Please see Figures 1 to 5 An agricultural vehicle axle, in this embodiment including:

[0028] The shaft tube 13 and two shaft head assemblies 12 are symmetrically distributed at both ends of the shaft tube 13. Each shaft head assembly 12 includes a plug rod 17 and a plug plate 18. Both ends of the shaft tube 13 are plugged into the plug rod 17 and the plug plate 18 through a tube swallowing process. Two fasteners 5 are provided at the top of the shaft tube 13. The end face of the fastener 5 passes through the shaft tube 13 and is threaded to the plug plate 18. The side of the plug plate 18 is connected to the plug rod 17. The end face of the plug rod 17 is connected to the abutment plate 14. The side of the abutment plate 14 is connected to the shaft rod 15. The side of the shaft rod 15 is sequentially fitted with an oil seal 2 10, a bearing 2 9, an oil seal 1 2, a bearing 1 1, and a hub body 6.

[0029] In this embodiment, the shaft rod 15 of the shaft head assembly 12 is sequentially fitted with oil seal 10, bearing 9, oil seal 2, bearing 1, and hub body 6. Oil seal 10, bearing 9, oil seal 2, and bearing 1 are all located within the inner cavity of the hub body 6. The shaft head assembly 12 is connected to the hub body 6 via a threaded connection between the shaft head nut 3 and the stud 16. Two shaft head assemblies 12 are symmetrically arranged at both ends of the shaft tube 13, with the insertion rod 17 and insertion plate 18 of the shaft head assembly 12 extending into the inner cavity of the shaft tube 13. The dimensions of the inner cavity of the shaft tube 13 match the dimensions of the insertion rod 17 and the insertion plate 18. The fastener 5 consists of a threaded post, a connecting rod, and a head. The bottom surface of tube 13 has two through slots for inserting connecting rods, and the top surface of the insertion plate 18 has a limiting groove for inserting connecting rods. At the same time, the inner cavity of the limiting groove of the insertion plate 18 has a threaded groove for threaded connection of the threaded column. The connecting rod of the fastener 5 passes through the inner top wall of the shaft tube 13 and extends into the groove of the insertion plate 18. During the rotation of the fastener 5, the threaded column moves along the threaded groove of the insertion plate 18. During the transmission process, the bottom surface of the head of the fastener 5 abuts against the shaft tube 13, realizing the connection and fixation of the shaft tube 13 and the shaft head assembly 12. The tube swallowing process makes the finished axle tough, strong, and pressure resistant, not easy to deform, improves the load-bearing capacity, and also saves costs.

[0030] Specifically, the two abutting plates 14 abut against the shaft tube 13 on one side towards the center, and the end face of the shaft rod 15 is fixedly connected with a stud 16, and the stud 16 is threadedly connected with a shaft head nut 3.

[0031] In this embodiment, after the plug rod 17 and the plug plate 18 extend into the designated position in the inner cavity of the shaft tube 13, the fastener 5 connects and fixes the shaft head assembly 12 and the shaft tube 13. At the same time, the two abutting plates 14 are tightly abutted against the shaft tube 13 on their adjacent sides. The connection between the shaft head assembly 12 and the hub body 6 is achieved through the threaded connection between the stud 16 and the shaft head nut 3.

[0032] Specifically, the wheel hub body 6 is threadedly connected to the wheel hub end cap 4.

[0033] In this embodiment, the hub end cap 4 is threadedly connected to the threaded portion of the hub body 6, so that the hub end cap 4 covers the inner cavity of the hub body 6. During use, the inner cavity of the hub body 6 needs to be filled with grease, and the hub end cap 4 covers the grease in the inner cavity of the hub body 6.

[0034] Specifically, the axle tube 13 is made of T700 special steel, a sealing ring is installed in the external thread sealing groove of the hub body 6, and a dust cover 11 is installed between the abutment plate 14 and the hub body 6.

[0035] In this embodiment, the sealing ring and dust cover 11 further shield the grease in the inner cavity of the wheel hub body 6, thereby improving the structural stability of the axle components.

[0036] Specifically, an anti-detachment pin is provided at the connection between the shaft head nut 3 and the stud 16, and a fixing bolt 7 and a fixing nut 8 are provided on the hub body 6. Bearing 1, oil seal 2, bearing 2, and oil seal 2 are located in the inner cavity of the hub body 6.

[0037] In this embodiment, the anti-detachment pin is provided to prevent the axle head nut 3 from falling off from the stud 16, thereby further improving the structural stability of the axle components.

[0038] Working principle

[0039] When using this agricultural vehicle axle, the user connects the axle 15 sequentially with the oil seal 10, bearing 9, oil seal 2, bearing 1 and wheel hub body 6. The oil seal 10, bearing 9, oil seal 2 and bearing 1 are located in the inner cavity of the wheel hub body 6 and are installed by threaded connection between the stud 16 and the axle head nut 3.

[0040] Two shaft head assemblies 12 are symmetrically arranged at both ends of the shaft tube 13, so that the insertion rod 17 and the insertion plate 18 of the shaft head assembly 12 extend into the inner cavity of the shaft tube 13. The shaft tube 13 is connected and fixed to the insertion plate 18 by fasteners 5, and at the same time, the two abutting plates 14 are in close contact with the shaft tube 13 on their adjacent sides.
