Description

Technical Field

[0001] This utility model relates to the field of mining vehicle technology, specifically to a transition structure for the drive shaft of a mining vehicle. Background Technology

[0002] The driveshaft is a crucial component in an automotive transmission system, consisting of a shaft tube, a telescopic sleeve, and a universal joint. During vehicle operation, the angle and distance between the gearbox output shaft and the drive axle input shaft constantly change due to road conditions, suspension movement, and other factors. The universal joint adapts to these angle changes, ensuring efficient power transmission from the driveshaft at different angles; the telescopic sleeve compensates for changes in distance, ensuring that power transmission is not interrupted or affected by changes in distance.

[0003] The power output from the engine is first transmitted to the gearbox. After passing through different gears and torque distribution within the gearbox, the power is output to the driveshaft. The driveshaft then transmits the rotation output from the gearbox to the final drive of the axle. The final drive then distributes the power to the left and right half-shafts, ultimately driving the wheels to rotate and generating driving force for the car.

[0004] Existing driveshafts connecting the gearbox and axle generally have length and angle requirements. Mining trucks typically have a three-axle structure, and as their tonnage increases, the wheelbase also lengthens. This can cause the driveshaft length to exceed the specified length, necessitating the division of the driveshaft into two sections to reduce the length of a single driveshaft. Currently, the driveshaft and frame each have their own brackets, connected by bolts for installation. This is simple and convenient, but because the installation is a rigid connection, the severe vibrations generated during mining truck operation can cause varying degrees of damage to the brackets, and in severe cases, even driveshaft detachment. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a transition structure for the drive shaft of a mining vehicle, thereby solving the problem of severe vibration causing damage to the support and resulting in the drive shaft falling off. This utility model provides a transition structure for the drive shaft of a mining car, comprising: A drive shaft connecting bracket is connected to a drive shaft, and the top of the drive shaft connecting bracket forms a horizontally positioned first connecting section; A flexible gasket is disposed on the first connecting segment; A frame connecting bracket is disposed on the flexible pad; a horizontally arranged second connecting section is formed at the bottom of the frame connecting bracket, and the flexible pad is disposed between the first connecting section and the second connecting section, and the first connecting section and the second connecting section are connected.

[0006] As can be seen from the above technical solution, the present invention provides a transition structure for the transmission shaft of a mining vehicle, wherein the transmission shaft connecting bracket and the transmission shaft are connected, and the frame connecting bracket and the frame are connected. The transmission shaft connecting bracket and the frame connecting bracket are respectively formed with a horizontal first connecting section and a second connecting section. A flexible gasket is provided between the first connecting section and the second connecting section. When the vehicle is running, the vibration of the vehicle body will cause the transmission shaft assembly to swing significantly, thereby impacting the bracket. The flexible gasket can effectively weaken and absorb the vibration, thereby reducing the damage to the bracket and other components.

[0007] Optionally, the frame connecting bracket includes: A frame connection part, connected to the frame, the frame connection part including a horizontally arranged third connection section; The drive shaft connection part is connected to the frame connection part, and the second connection section is located at the bottom of the drive shaft connection part; Ribs are spaced apart between the third connecting section and the second connecting section.

[0008] As can be seen from the above technical solution, by setting stiffeners in the frame connection part and the drive shaft connection part bracket to ensure its own strength, it can effectively resist the damage caused by vibration.

[0009] Optionally, the frame connection portion further includes a reinforcing section, which is formed by bending the third connection section, and the reinforcing section is connected to the frame.

[0010] Optionally, both the third connecting section and the reinforcing section are provided with through holes for bolting to the vehicle frame.

[0011] As can be seen from the above technical solution, the third connecting section and the reinforcing section of the frame connection are both provided with through holes for fitting and tightening with the frame crossbeam. This ensures that when one or more bolts loosen, the bolts in other positions can continue to provide a fixing effect, so as to avoid the situation where the drive shaft falls off and damages other parts.

[0012] Optionally, the drive shaft connecting bracket includes: A bearing, wherein the inner ring of the bearing is connected to the drive shaft; A support portion is disposed at the bottom of the bearing, and the two ends of the support portion form the first connecting section.

[0013] As can be seen from the above technical solutions, when the drive shaft connecting bracket and the frame connecting bracket are fixed, the drive shaft can still rotate freely around the axis. The support part can improve the stability of the drive shaft connection and prevent the drive shaft from falling off.

[0014] Optionally, the drive shaft connecting bracket further includes a receiving part, which is connected to the outer ring of the bearing, and the receiving part is also connected to the supporting part.

[0015] Optionally, a horizontally arranged fourth connecting segment is formed at the top of the receiving part.

[0016] Optionally, the flexible pad is made of rubber.

[0017] By adopting the above technical solution, this application has the following technical effects: This utility model provides a transition structure for the drive shaft of a mining vehicle. The drive shaft connecting bracket is connected to the drive shaft, and the frame connecting bracket is connected to the frame. The drive shaft connecting bracket and the frame connecting bracket are respectively formed with a horizontal first connecting section and a second connecting section. A flexible gasket is provided between the first connecting section and the second connecting section. When the vehicle is running, the vibration of the vehicle body will cause the drive shaft assembly to swing significantly, thereby impacting the bracket. The flexible gasket can effectively weaken and absorb the vibration, thereby reducing damage to the bracket and other components. Attached Figure Description

[0025] Based on the above structure, the drive shaft connecting bracket 1 and the drive shaft 2' are connected, and the frame connecting bracket 3 and the frame crossbeam 1' are connected. The drive shaft connecting bracket 1 and the frame connecting bracket 3 respectively form a horizontal first connecting section 121 and a second connecting section 321. A flexible gasket 2 is provided between the first connecting section 121 and the second connecting section 321. When the vehicle is running, the vibration of the vehicle body will cause the drive shaft assembly to swing significantly, thereby impacting the bracket. The flexible gasket 2 can effectively weaken and absorb the vibration, thereby reducing damage to the bracket and other components.

[0026] Optionally, only one flexible gasket 2 is provided in this embodiment. In actual application, the number of flexible gaskets 2 depends on the situation and is not specifically limited.

[0027] like Figure 2-3 As shown, the frame connecting bracket 3 includes: The frame connection part 31 is connected to the frame crossbeam 1'. The frame connection part 31 includes a horizontally arranged third connection section 311. The drive shaft connection part 32 is connected to the frame connection part 31, and the second connection section 321 is located at the bottom of the drive shaft connection part 32; Rib plates 33 are spaced apart between the third connecting section 311 and the second connecting section 321.

[0028] By providing stiffeners 33 at the frame connection portion 31 and the drive shaft connection portion 32, their strength is ensured, and they can effectively resist the destructive effects of vibration. The frame connection portion 31 and the drive shaft connection portion 32 are both 10mm thick, while the stiffeners 33 are 8mm thick. In this embodiment, the material of the frame connection bracket 3 is thickened to ensure its strength and effectively resist the destructive effects of vibration.

[0029] Optionally, the frame connection portion 31 further includes a reinforcing section 312, which is formed by bending the third connection portion 311, and the reinforcing section 312 is connected to the frame.

[0030] Optionally, both the third connecting section 311 and the reinforcing section 312 are provided with through holes 313 for bolting to the frame. The third connecting section 311 and the reinforcing section 312 of the frame connecting part 31 are provided with through holes 313 for fitting and tightening with the frame crossbeam 1', ensuring that when one or more bolts 4 loosen, the bolts 4 in other positions can continue to provide a fixing effect with the nuts 5, so as to avoid the situation where the drive shaft falls off and damages other parts.

[0031] like Figure 3 As shown, the through hole 313 on the reinforcing section 312 is oblong, and the through hole 313 on the third connecting section 311 is circular, which can ensure that the reinforcing section 312 and the third connecting section 311 can be fitted and tightened with the frame crossbeam 1'.

The support portion 12 is located at the bottom of the bearing 11, and the two ends of the support portion 12 form first connecting sections 121. When the drive shaft connecting bracket 1 and the frame connecting bracket 3 are fixed, the drive shaft 2' can still rotate freely around the axis. The support portion 12 can improve the stability of the drive shaft 2' connection and prevent the drive shaft 2' from falling off.

[0033] Optionally, the drive shaft connecting bracket 1 further includes a receiving part 13, which is connected to the outer ring of the bearing 11, and the receiving part 13 is also connected to the supporting part 12.

[0035] Optionally, the flexible gasket 2 is made of rubber.

[0036] Based on the technical solution of this embodiment, in specific applications, firstly, by setting a flexible gasket 2 between the drive shaft connecting bracket 1 and the frame connecting bracket 3, the original rigid connection is improved into a soft connection with a buffering effect, effectively reducing and absorbing vibration, thereby reducing damage to the bracket and other components; secondly, by increasing the mounting holes of the frame connecting bracket 3, the connection strength between the frame connecting bracket 3 and the frame crossbeam 1' is improved, ensuring the connection effect between the drive shaft 2' and the frame crossbeam 1'; finally, the frame connecting bracket 3 is buffered by the stiffening plate 33, ensuring the strength of the frame connecting bracket 3 itself, and can effectively resist the destructive force caused by vibration.
