Description

Technical Field

[0001] The utility model relates to an auxiliary device for replacing a clutch driven disc, belonging to the field of heavy-duty commercial vehicles. Background Art

[0002] With the continuous research, exploration and development of heavy-duty commercial vehicle design innovation technology, many types of fixed support methods for heavy-duty truck power system assemblies have emerged. Figure 1 As shown, such as engine assembly front end A+engine assembly flywheel end B, engine assembly front end A+transmission assembly stop end C, engine assembly front end A+transmission assembly middle end D, engine assembly front end A+engine assembly flywheel end B+transmission assembly auxiliary support end E, engine assembly front end A+transmission assembly stop end C+transmission assembly auxiliary support end E.

[0003] In the current heavy-duty truck industry, for the three fixed support methods of the power system assembly, namely, the front end A of the engine assembly + the stop end C of the gearbox assembly, the front end A of the engine assembly + the middle end D of the gearbox assembly, and the front end A of the engine assembly + the stop end C of the gearbox assembly + the auxiliary support end E of the gearbox assembly, the maintenance and replacement of the driven disc on the clutch is relatively cumbersome, and the replacement time is long, which affects the attendance efficiency of the vehicle. The installation position of the driven disc is described as follows: Figure 2 As shown, the clutch driven disc assembly 2, the clutch cover and pressure plate assembly 3, and the clutch release bearing assembly 4 are combined together to form a clutch assembly, which is fixed on the flywheel 1 of the engine assembly by bolts, and then the flywheel 1 and the gearbox assembly stop 5 are connected together by bolts to form a power system assembly. During the maintenance and repair of the whole vehicle, since the driven disc fixed on the clutch between the engine and the gearbox is a maintenance part, in order to replace the driven disc, it is necessary to remove all the fixing points of the entire power system assembly and lift it out from the frame to complete the replacement. This replacement operation process is relatively cumbersome and the replacement time is long, which affects the attendance efficiency of the vehicle; and in application areas such as construction sites, mining areas, coal plants, and sand and stone plants, the dump trucks transport goods back and forth and the working hours are long. There is a situation where people do not rest the vehicle, and the road conditions of the whole vehicle are bad, which causes the driven disc on the clutch to wear quickly and be replaced frequently.

[0024] like Figure 3 , Figure 4 As shown, an auxiliary device for replacing a clutch driven plate comprises an auxiliary support rod 11, a connecting plate movably mounted on the auxiliary support rod 11, and a support rod limiting assembly 10 for limiting the two ends of the auxiliary support rod 11;

[0025] The auxiliary support rod 11 is cylindrical;

[0026] The connecting plate includes a left connecting plate 12 and a right connecting plate 13, one end of the left connecting plate 12 and the right connecting plate 13 is sleeved on the auxiliary support rod 11, and the other end is connected to the left and right sides of the flywheel 1 respectively;

[0027] The two support rod limit assemblies 10 are relatively placed on the upper wing surfaces of the frame on the left and right sides of the frame assembly 9. The support rod limit assembly 10 includes a flat plate 10-1 and two limit blocks 10-2 fixed on the flat plate 10-1. The end of the auxiliary support rod 11 is limited and placed between the flat plate 10-1 and the two limit blocks 10-2.

[0028] In some embodiments, Figure 4 As shown, the left connecting plate 12 and the right connecting plate 13 are both provided with mounting holes for movably mounting the auxiliary support rod 11, and the aperture of the mounting holes is larger than the diameter of the auxiliary support rod 11. Relying on the large-aperture mounting holes, the left connecting plate 12 and the right connecting plate 13 can be conveniently mounted on the auxiliary support rod 11, and the left connecting plate 12 and the right connecting plate 13 can flexibly adjust the installation position on the auxiliary support rod 11.

[0029] In some embodiments, Figure 4 As shown, bolt holes are respectively opened on the left connecting plate 12 and the right connecting plate 13, and the left connecting plate 12 and the right connecting plate 13 are respectively connected to the flywheel 1 by bolts, so that disassembly and assembly are convenient.

[0030] In some embodiments, Figure 4 As shown, the two limit blocks 10 - 2 are welded on the flat plate 10 - 1 , so that the overall structure of the support rod limit assembly 10 is more stable.

[0031] In some embodiments, Figure 4 As shown, a gap matching the diameter of the auxiliary support rod 11 is provided between the two limit blocks 10-2, ensuring that the end of the auxiliary support rod 11 is placed in the space between the flat plate 10-1 and the two limit blocks 10-2 without obvious position movement, thereby ensuring the support stability of the engine assembly 6.

[0032] In some embodiments, Figure 4 As shown, the flat plate 10-1 has a certain thickness, ensuring that when the end of the auxiliary support rod 11 is placed on the flat plate 10-1, the support height of the auxiliary support rod 11 cooperates with the front end A of the engine assembly to form a stable support structure, so that the engine assembly 6 is in a horizontal state, avoiding the engine assembly 6 from tilting due to inconsistent support heights at the front and rear ends of the engine assembly 6.

[0033] For the power system assemblies with three fixed support methods, namely, the front end A of the engine assembly + the stop end C of the gearbox assembly, the front end A of the engine assembly + the middle end D of the gearbox assembly, and the front end A of the engine assembly + the stop end C of the gearbox assembly + the auxiliary support end E of the gearbox assembly, when the clutch needs to be replaced, considering that the support point on the gearbox assembly 8 needs to be removed, at this time, only the front end A of the engine assembly plays a supporting role, so the rear end of the engine assembly 6 will tilt and sink;

[0034] For this reason, Figure 3 As shown, the two support rod limit assemblies 10 of the utility model are placed on the upper wing surfaces of the frame on the left and right sides of the frame assembly 9, and then the left connecting plate 12 and the right connecting plate 13 are respectively connected to the flywheel 1 of the engine assembly 6 by bolts, and then the auxiliary support rod 11 is inserted into the mounting holes on the left connecting plate 12 and the right connecting plate 13, and the two ends of the auxiliary support rod 11 are respectively placed between the flat plate 10-1 and the two limit blocks 10-2 of the support rod limit assembly 10, and the auxiliary device 7 is installed;

[0035] When the gearbox assembly 8 is disassembled, the engine assembly 6 is maintained in a horizontal supporting state by the support of the front end A of the engine assembly and the auxiliary support rod 11 at the rear end. The clutch assembly is then taken out and the driven disc inside is replaced, and then installed back into the flywheel 1. Finally, the gearbox is reset, and the maintenance and replacement of the driven disc is completed.

[0036] The auxiliary device for replacing the clutch driven disc of the utility model is connected with the flywheel to form a stable supporting structure at the front and rear ends of the engine assembly, which provides strong support for the maintenance of the driven disc of the vehicle, greatly improves the replacement efficiency of the driven disc, reduces service hours and saves labor costs generated in service activities, and also greatly ensures the long-term operation of heavy-duty trucks.

[0037] In addition, those skilled in the art will understand that, although some embodiments described herein include certain features included in other embodiments but not other features, the combination of features of different embodiments also means being within the scope of protection of the present utility model and forming different embodiments. For example, in the above embodiments, those skilled in the art can use them in combination according to the known technical solutions and the technical problems to be solved by the present application.
