Description

Technical Field

[0001] The invention relates to the field of special vehicle chassis modification devices, and in particular to a transitional power transmission device. Background Art

[0002] With the acceleration of modernization, the field of special vehicles has ushered in unprecedented development opportunities, but also faces increasingly complex and changing market demands. As vehicles that perform specific tasks or functions, the demands for the upper parts (such as firefighting equipment, lifting machinery, sanitation facilities, etc.) of special vehicles are highly diversified and customized. This trend directly leads to different demands for brands and models of power take-offs or transfer cases, which greatly increases the complexity of vehicle design and production.

[0003] Usually, many special-purpose vehicles are pre-installed with a power take-off or transfer case during chassis design. Universal joints are installed on the output shaft and input shaft mounting parts of the drive shaft, and are connected to the power take-off or transfer case through the universal joints. When the power transmission of the special-purpose vehicle needs to be modified, the modification can be made directly on the power take-off or transfer case.

[0004] When modifying the power take-off or separator, the power take-off or transfer case that comes with the chassis often limits the user's modification space and interface flexibility, making it difficult for the user to flexibly adjust or upgrade the upper equipment according to actual needs, reducing the versatility of the chassis and making it difficult to flexibly modify the power transmission of special vehicles. Summary of the invention

[0005] The present application provides a transitional power transmission device, which can solve the technical problem in the prior art that it is difficult to flexibly modify the power transmission of a special vehicle chassis.

[0006] The embodiment of the present application provides a transitional power transmission device, which includes:

[0007] A transition transmission shaft, the two ends of which in the length direction are respectively used to connect the mounting end of the output transmission shaft and the mounting end of the input transmission shaft;

[0008] Two transition fixed mounting parts, the transition fixed mounting parts include a fixed lower bracket and a connecting bearing, the connecting bearing is rotatably arranged on the fixed lower bracket, the two fixed lower brackets are respectively fixed at two ends of the transition transmission shaft in the length direction, and the two ends of the transition transmission shaft are respectively passed through the two connecting bearings;

[0009] And, a transition mounting bracket, the two fixed lower brackets are arranged on the transition mounting bracket, and the transition mounting bracket is used for detachable connection with the special vehicle chassis.

[0010] By adopting the above technical scheme, a detachable transition mounting bracket is added to the special-purpose vehicle chassis, and the two ends of the transition drive shaft are respectively connected to the output drive shaft and the output drive shaft, which can not only transmit power normally, but also play a role in positioning the input drive shaft and the output drive shaft, thereby ensuring the normal driving of the special-purpose vehicle chassis before modification; when it is necessary to modify the power system of the special-purpose vehicle chassis, the transition drive shaft is removed from the mounting parts of the input drive shaft and the output drive shaft, and the transition mounting bracket is removed from the special-purpose vehicle chassis, and a new power transmission device can be installed between the input drive shaft and the output drive shaft, which greatly improves the self-use of power modification and solves the problem of difficulty in flexibly modifying the power transmission of the special-purpose vehicle chassis in the prior art.

[0011] In one embodiment, the transition fixed mounting member further comprises:

[0012] A vibration isolation pad is arranged on the contact surface between the fixed lower bracket and the connecting bearing.

[0013] By adopting the above technical solution, the vibration isolation pad is coated on the contact surface between the fixed lower bracket and the connecting bearing. When the transition transmission shaft drives the connecting bearing to rotate in the fixed lower bracket, the vibration isolation pad can reduce the vibration of the transition transmission shaft, thereby reducing the power loss of the transition transmission shaft when transmitting power. The material of the vibration isolation pad can be a flexible material with good vibration reduction effect, such as rubber pad, polyurethane, silicone, etc.

[0014] In one embodiment, the transition mounting bracket comprises:

[0015] A fixed side bracket, two of which are provided, and the two fixed side brackets are used to be connected to the chassis of the special vehicle;

[0016] And, a supporting crossbeam, wherein the supporting crossbeam is arranged between the two fixed side brackets, and the two fixed lower brackets are arranged on the supporting crossbeam.

[0017] By adopting the above technical solution, the two fixed side brackets are connected to the special vehicle chassis, and then the supporting beam is fixed between the two fixed side brackets, so that the two fixed side brackets and the supporting beam can form a stable connection structure, and are temporarily fixed to the special vehicle chassis as a whole, which not only enhances the bearing capacity of the entire transition mounting bracket, but also provides a reliable supporting installation platform for the subsequent fixed lower bracket installed on the supporting beam.

[0018] In one embodiment, a height adjustment device for adjusting the installation height of the fixed lower bracket is also provided on the supporting crossbeam.

[0019] By adopting the above technical solution, the connection height of the output transmission shaft and the input transmission shaft in different special vehicles can be adapted.

[0020] In one embodiment, the height adjustment device includes an L-shaped vertical hanger, two L-shaped vertical hangers are provided, and are respectively arranged at the two ends of the supporting beam close to the output drive shaft and the input drive shaft, the vertical portion of the L-shaped vertical hanger extends vertically upward from the surface of the supporting beam, the transverse mounting portion of the L-shaped vertical hanger extends toward the direction of the output drive shaft or the input drive shaft, and the fixed lower bracket is arranged on the transverse mounting portion of the L-shaped vertical hanger.

[0021] By adopting the above technical solution, during the installation of the transition drive shaft, the height of the L-shaped vertical hanger lateral installation portion on the vertical portion of the L-row vertical hanger is adjusted, so that the installation height of the transition drive shaft between the lower brackets can be adjusted and fixed.

[0022] In one embodiment, a support reinforcement member is provided on the L-shaped vertical hanger, and the support reinforcement member is provided between the vertical portion of the L-shaped vertical hanger and the transverse installation portion of the L-shaped vertical hanger.

[0023] By adopting the above technical solution, the supporting reinforcement member can provide additional inclined supporting force between the vertical part of the L-shaped vertical hanger and the horizontal mounting part of the L-shaped vertical hanger, thereby improving the connection strength of the L-shaped vertical hanger and providing stable support for the fixed lower bracket below.

[0024] In one embodiment, a plurality of mounting holes are formed on the two fixed side brackets, and mounting bolts are inserted into the mounting holes. The mounting bolts are used to fix the fixed side brackets on the chassis of the special vehicle.

[0025] By adopting the above technical solution and using a threaded connection method, a tight fixation between the fixed side bracket and the special vehicle chassis is achieved. This simple connection method is convenient for operators to install and disassemble, and is more convenient to use.

[0026] In one embodiment, both ends of the supporting beam are detachably connected to the two fixed side brackets via connecting bolts.

[0027] By adopting the above technical solution, during the installation of the support beam, the technician only needs to pass the connection bolt through the reserved hole and then tighten it with a wrench or screwdriver to easily achieve a stable connection between the support beam and the fixed side bracket. Similarly, when the support beam needs to be disassembled, it is only necessary to loosen the bolt to easily remove the beam from the fixed bracket. This connection method is simple and easy to master, so that even technicians who are new to it can quickly get started, greatly reducing the difficulty of operation. In addition, the bolt connection method is also highly reliable. Since the bolt connection is achieved through the tight fit of the thread, it has a high shear and tensile resistance. This means that when the support beam is subjected to a large load or is subjected to external forces such as vibration, the bolt connection can still maintain a stable connection between the support beam and the fixed side bracket, thereby maintaining overall stability and safety.

[0028] In one embodiment, both ends of the transition transmission shaft in the length direction are flange-connected to the mounting end of the output transmission shaft and the mounting end of the input transmission shaft, respectively.

[0029] By adopting the above technical solution, the flange connection has good tightness, so as to improve the connection strength between the transition drive shaft and the output drive shaft and the input drive shaft, thereby reducing the power loss during the power transmission process, and better play the role of transitional power transmission between the output drive shaft and the input drive shaft; in addition, the flange connection adopts a bolt fastening method, which makes the installation and disassembly process of the transition drive shaft and the output drive shaft and the input drive shaft simpler and more convenient. The operator only needs to use suitable tools, such as a wrench or a screwdriver, to easily complete the installation and disassembly of the flange connection. This convenience not only improves work efficiency, but also reduces safety risks during installation and disassembly. In addition, when maintaining the connection between the transition drive shaft and the output drive shaft and the input drive shaft in the future, the operator can check the tightness of the flange connection at any time, promptly discover and deal with possible looseness and other problems, and convenient maintenance, which further improves the safety and stability of the connection between the transition drive shaft and the output drive shaft and the input drive shaft.

[0030] In one embodiment, the fixed lower bracket and the transition mounting bracket are both made of steel.

[0031] By adopting the above technical solution, the steel material has good high strength, toughness and excellent mechanical properties, and is a better choice for making the fixed lower bracket and the transition mounting bracket. The use of steel as the manufacturing material for the fixed lower bracket and the transition mounting bracket can not only effectively improve the bearing capacity and deformation resistance of the fixed lower bracket and the transition mounting bracket, but also extend the service life of the fixed lower bracket and the transition mounting bracket to a certain extent. In addition, the good corrosion resistance and wear resistance of steel are also important reasons for choosing it as the manufacturing material for the fixed lower bracket and the transition mounting bracket. During long-term use, the steel material can show better durability and stability, thereby ensuring the overall performance and reliability of the fixed lower bracket and the transition mounting bracket.

[0032] The beneficial effects brought by the technical solution provided in the embodiments of the present application include:

[0033] By adding a detachable transition mounting bracket to the special-purpose vehicle chassis, the two ends of the transition drive shaft are respectively connected to the output drive shaft and the output drive shaft, which can not only transmit power normally, but also play a role in positioning the input drive shaft and the output drive shaft, thereby ensuring the normal driving of the special-purpose vehicle chassis before modification; when it is necessary to modify the power system of the special-purpose vehicle chassis, the transition drive shaft is removed from the mounting parts of the input drive shaft and the output drive shaft, and the transition mounting bracket is removed from the special-purpose vehicle chassis, and a new power transmission device can be installed between the input drive shaft and the output drive shaft, which greatly improves the self-use of power modification and solves the problem of difficulty in flexibly modifying the power transmission of the special-purpose vehicle chassis in the prior art.

DETAILED DESCRIPTION

[0038] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] The embodiment of the present application provides a transitional power transmission device, which can solve the problem in the prior art that it is difficult to flexibly modify the power transmission of a special vehicle chassis.

[0040] The present application embodiment is explained in a state where a transition transmission shaft is installed in a vehicle chassis. Figure 1 A schematic diagram of the structure of a transitional power transmission device installed in a special vehicle chassis in the present application, a transitional power transmission device disclosed in the present application, including a transitional transmission shaft 1, two transitional fixed mounting parts and a transitional mounting bracket, the transitional mounting bracket is detachably connected to the special vehicle chassis 4, the two transitional fixed mounting parts are arranged on the transitional mounting bracket, and the two transitional fixed mounting parts are arranged on the transitional mounting bracket at intervals along the extension direction of the output transmission shaft 5 and the input transmission shaft 6 of the special vehicle. The transitional fixed mounting part includes a fixed lower bracket 2 and a connecting bearing 21, the connecting bearing 21 is rotatably arranged on the fixed lower bracket 2, and the two ends of the transitional transmission shaft 1 in the length direction pass through the two connecting bearings 21 and are detachably connected to the mounting ends of the output transmission shaft 5 and the mounting ends of the input transmission shaft 6, respectively.

[0041] The transition transmission shaft 1 is interference-fitted in the two connecting bearings 21. When the transition transmission shaft 1 receives the power transmitted by the input transmission shaft 6, the transition transmission shaft 1 rotates synchronously in the two fixed lower brackets 2 by driving the connecting bearings 21, and transmits the power of the input transmission shaft 6 to the output transmission shaft 5 synchronously, that is, the transition transmission shaft 1 plays the role of transition connection between the input transmission shaft 6 and the output transmission shaft 5. It can not only transmit power normally, but also play the role of positioning the input transmission shaft 6 and the output transmission shaft 5, thereby ensuring the normal driving of the special vehicle chassis 4 before modification. When the power system of the special vehicle chassis 4 needs to be modified, the transition mounting bracket is removed from the special vehicle chassis 4, and the transition transmission shaft 1 is removed from between the input transmission shaft 6 and the output transmission shaft 5, so that the entire transition type power transmission device can be removed from the special vehicle chassis 4, and the new power transmission device is installed between the input transmission shaft 6 and the output transmission shaft 5, which greatly improves the self-use degree of the power modification of the special vehicle, and solves the problem of difficulty in flexibly modifying the power transmission of the special vehicle chassis 4 in the prior art.

[0042] More specifically, the mounting ends of the output drive shaft 5 and the mounting ends of the input drive shaft 6 are both provided with universal joints to facilitate the transmission and reception of power in different directions. In order to enable the transition drive shaft 1 to more closely connect the output drive shaft 5 and the input drive shaft 6, connecting flanges are welded at both ends of the length direction of the transition drive shaft 1, and are detachably connected to the output drive shaft 5 and the input drive shaft 6 through flange connections.

[0043] The flange connection connects the transition transmission shaft 1 with the output transmission shaft 5 and the input transmission shaft 6 through fasteners such as flanges and bolts, and has good fastening properties. Therefore, it can improve the connection strength between the transition transmission shaft 1 and the output transmission shaft 5 and the input transmission shaft 6, thereby reducing the power loss during the power transmission process, and better play the role of transitional power transmission between the output transmission shaft 5 and the input transmission shaft 6. In addition, the flange connection adopts a bolt fastening method, which makes the installation and disassembly process of the transition transmission shaft 1 and the output transmission shaft 5 and the input transmission shaft 6 simpler and more convenient. The operator only needs to use suitable tools, such as a wrench or a screwdriver, to easily complete the installation and disassembly of the flange connection. This convenience not only improves work efficiency, but also reduces safety risks during installation and disassembly. In addition, when the connection between the transition transmission shaft 1 and the output transmission shaft 5 and the input transmission shaft 6 is maintained in the future, the operator can check the fastening state of the flange connection at any time, promptly discover and deal with possible looseness and other problems, and the maintenance is convenient, which further improves the safety and stability of the connection between the transition transmission shaft 1 and the output transmission shaft 5 and the input transmission shaft 6.

[0044] In one embodiment of the present application, referring to Figure 2The present application is a cross-sectional view of a transition fixed mounting member in a transitional power transmission device, wherein the fixed lower bracket 2 is specifically configured as a semicircular fixed bracket to better fit the shape of the transition transmission shaft 1, and the connecting bearing 21 is coaxially arranged on the circular fixed bracket of the fixed lower bracket 2, and the transition transmission shaft 1 can drive the connecting bearing 21 to rotate synchronously in the fixed lower bracket 2 when receiving power. Further, in order to reduce the loss during power transmission, the transition fixed mounting member also includes a vibration isolation pad 22, which is coated on the contact surface between the fixed lower bracket 2 and the connecting bearing 21. When the transition transmission shaft 1 drives the connecting bearing 21 to rotate in the fixed lower bracket 2, the vibration isolation pad 22 can play a role in shock absorption for the transition transmission shaft 1, thereby reducing the power loss of the transition transmission shaft 1 when transmitting power. The vibration isolation pad 22 can be specifically made of a flexible material such as a rubber pad with good shock absorption effect and easy processing. In other embodiments, the material of the vibration isolation pad 22 can also be replaced according to the cost and demand conditions in the early stage of manufacturing, such as polyurethane, silicone and other materials. Among them, silicone material has excellent high and low temperature resistance and chemical stability, and is suitable for use in extreme temperatures or corrosive environments, but the cost is relatively high. The specific material selection can be flexibly changed according to actual needs.

[0045] Reference Figure 1 The schematic diagram of the structure of a transitional power transmission device installed in the chassis of a special vehicle in the present application. In order to facilitate the installation and removal of the transitional mounting bracket on the chassis 4 of the special vehicle, the transitional mounting bracket includes two fixed side brackets 3 and a supporting crossbeam 31. The two fixed side brackets 3 are detachably connected to the chassis 4 of the special vehicle on both sides of the extension direction of the output transmission shaft 5 and the input transmission shaft 6, respectively. The two ends of the supporting crossbeam 31 in the length direction are respectively connected to the two fixed side brackets 3, and the two fixed lower brackets 2 are installed on the supporting crossbeam 31 at intervals. Under the premise of ensuring that the transitional mounting bracket has sufficient strength, by adopting a detachable connection, such as a bolted connection, the operator can easily install and remove the two fixed side brackets 3 and the supporting crossbeam 31, which greatly improves the work efficiency.

[0046] More specifically, the fixed side bracket 3 is provided with a plurality of mounting holes, and mounting bolts 32 are inserted into the mounting holes. The two fixed side brackets 3 are fixed to the special vehicle chassis 4 by the plurality of mounting bolts 32, and are tightly fixed to the fixed side bracket 3 and the special vehicle chassis 4 by threaded connection. When performing installation operations, the staff only needs to use appropriate tools, such as a wrench or a screwdriver, to tighten each mounting bolt 32 in turn, and the installation of the fixed side bracket 3 can be completed quickly and accurately. Similarly, when disassembly or maintenance is required, only the reverse operation is required, that is, the mounting bolts 32 are loosened, and the fixed side bracket 3 can be easily separated from the special vehicle chassis 4, which greatly simplifies the operation process and improves work efficiency.

[0047] Similarly, the two ends of the support crossbeam 31 in the length direction are detachably connected to the two fixed side brackets 3 by connecting bolts 33, and the installation and removal of the support crossbeam 31 can be completed by tightening or loosening the connecting bolts 33. The support crossbeam 31 not only provides a mounting fulcrum for the fixed lower bracket 2, but also enhances the connection strength between the two fixed side brackets 3 and the special vehicle chassis 4, temporarily connects the special vehicle chassis 4 on both sides of the extension direction of the output transmission shaft 5 and the input transmission shaft 6 as a whole, and further enhances the connection strength of the transition mounting bracket on the special vehicle chassis 4.

[0048] In one embodiment of the present application, the support beam 31 includes two beam units, and the two beam units are installed on the two fixed side brackets 3 at intervals along the extension direction of the output transmission shaft 5 and the input transmission shaft 6, and the two fixed lower brackets 2 are installed on the two beam units respectively. This arrangement can reduce the area of ​​the support beam 31, and can also reduce the manufacturing cost of the support beam 31 while reducing the weight of the special vehicle chassis 4. In other embodiments, when there are higher requirements for the support strength and connection strength of the support beam 31, the support beam 31 can also be directly designed as a solid plate. Although it will increase a certain weight and cost, the solid plate structure can provide a more uniform support force distribution and significantly improve the overall connection strength and support strength.

[0049] Furthermore, in order to adapt to the connection height of the output transmission shaft 5 and the input transmission shaft 6 in different special vehicles, a height adjustment device for adjusting the installation height of the fixed lower bracket 2 is also provided on the support crossbeam 31, which not only enhances the flexibility and adaptability of the installation of the fixed lower bracket 2, but also ensures that the transition transmission shaft 1 can achieve accurate inter-axis connection and stable support under different vehicle models and working conditions. The height adjustment device includes two L-shaped vertical hangers 311, which are respectively arranged at the two ends of the support crossbeam 31 close to the output transmission shaft 5 and the input transmission shaft 6, the vertical part of the L-shaped vertical hanger 311 extends vertically upward from the surface of the support crossbeam 31, and the lateral installation parts of the two L-shaped vertical hangers 311 extend toward the direction of the output transmission shaft 5 and the input transmission shaft 6, respectively, and the two fixed lower brackets 2 are respectively arranged on the lateral installation parts of the two L-shaped vertical hangers 311.

[0050] During the installation of the transition transmission shaft 1, the operator first fixes the vertical part of the L-shaped vertical hanger 311 on the supporting crossbeam 31. This position is determined according to the position height of the output transmission shaft 5 and the input transmission shaft 6 and the structure of the vehicle chassis. Then the operator installs the transverse mounting part of the L-shaped vertical hanger 311 on the vertical part of the L-shaped vertical hanger 311, and adjusts the height of the transverse mounting part of the L-shaped vertical hanger 311 on the vertical part of the L-shaped vertical hanger 311, so as to adjust the installation height of the transition transmission shaft 1 between the two fixed lower brackets 2 on the transverse mounting part of the L-shaped vertical hanger 311. This adjustment process requires not only high precision, but also requires the operator to have certain professional skills and experience. Because the installation height of the transition transmission shaft 1 directly affects its operating stability and power transmission efficiency, too high or too low may cause problems such as poor transmission and increased vibration. Therefore, when making adjustments, the operator can use professional measuring tools to improve the accuracy of the adjustment. In addition, in order to ensure that the transition drive shaft 1 can operate stably after installation, we also need to perform necessary fixation and inspection on the fixed lower bracket 2 to improve the stability and practicality of the overall structure.

[0051] In one embodiment of the application, a plurality of bolt holes are provided on the vertical part of the L-shaped vertical hanger 311 in the height direction, and a plurality of fixing bolts are threaded through the inner threads of the bolt holes. A fixing hole is provided on the transverse mounting part of the L-shaped vertical hanger 311, and the fixing bolts are passed through the bolt holes on the vertical part of the L-shaped vertical hanger 311 and the fixing holes on the transverse mounting part of the L-shaped vertical hanger 311 at the same time to complete the installation of the transition transmission shaft 1. The transverse mounting part of the L-shaped vertical hanger 311 is fixed in the bolt holes at different heights on the vertical part of the L-shaped vertical hanger 311 using fixing bolts, so as to change the installation height of the transition transmission shaft 1. In other embodiments, the vertical part of the L-shaped vertical hanger 311 and the transverse mounting part of the L-shaped vertical hanger 311 can also be set as an integral entity, and the installation height of the transverse mounting part of the L-shaped vertical hanger 311 is adjusted before the transition rotating shaft is installed to improve the connection strength between the vertical part of the L-shaped vertical hanger 311 and the transverse mounting part of the L-shaped vertical hanger 311.

[0052] In order to improve the supporting strength of the fixed lower bracket 2, a supporting reinforcement member 312 is further provided between the vertical portion of the L-shaped vertical hanger 311 and the horizontal mounting portion of the L-shaped vertical hanger 311 to increase the inclined supporting force between the vertical portion of the L-shaped vertical hanger 311 and the horizontal mounting portion of the L-shaped vertical hanger 311, thereby improving the connection strength of the L-shaped vertical hanger 311 and providing stable support for the fixed lower bracket 2 below.

[0053] In order to further improve the overall structural strength of the transitional power transmission device, the fixed lower bracket 2 and the transitional mounting bracket are made of steel. Steel material has good high strength, toughness and excellent mechanical properties, and is a better choice for making the fixed lower bracket 2 and the transitional mounting bracket. The use of steel as the manufacturing material for the fixed lower bracket 2 and the transitional mounting bracket can not only effectively improve the bearing capacity and anti-deformation capacity of the fixed lower bracket 2 and the transitional mounting bracket, but also extend the service life of the fixed lower bracket 2 and the transitional mounting bracket to a certain extent. In the early production process, these steel materials will undergo precise cutting, forming, welding and heat treatment and other process steps to improve the dimensional accuracy, surface finish and uniformity of the internal structure of the fixed lower bracket 2 and the transitional mounting bracket. These process measures further enhance the mechanical properties of the fixed lower bracket 2 and the transitional mounting bracket, so that it can better adapt to various emergencies that may be encountered during the operation of the transitional power transmission device.

[0054] In addition, the good corrosion resistance and wear resistance of steel are also important reasons for choosing it as the material for the fixed lower bracket 2 and the transition mounting bracket. During long-term use, steel can show better durability and stability, thereby ensuring the overall performance and reliability of the fixed lower bracket 2 and the transition mounting bracket.
