Description
Technical Field
[0001] The utility model relates to the technical field of tractor post-processor installation, in particular to a post-processor installation system for a large tractor. Background Art
[0002] The post-processor is a key component of the engine exhaust gas system. One end of the post-processor of the exhaust system is connected to the engine through a pipeline, and the other end is provided with an opening communicating with the atmospheric environment. The exhaust gas discharged from the engine is input into the post-processor through the pipeline for purification treatment. The harmful substances in the exhaust gas are purified and treated and then discharged into the atmosphere, avoiding the direct discharge of vehicle exhaust gas into the atmosphere and causing pollution to the air.
[0003] The post-processor is fixed on the vehicle frame of the whole vehicle through an installation bracket. The support reliability of the post-processor bracket is crucial for the entire post-processor and the whole vehicle. There are three technical problems existing in the post-processor brackets of existing large tractors: (1) To meet the strength requirements of the post-treatment bracket after installation, most of the post-processor installation brackets are designed with large volume, resulting in heavy weight and large occupied space, which brings trouble to the layout of the whole machine; (2) The too large volume of the installation bracket makes it difficult to arrange pipelines in the remaining space; (3) The extra space is not used for other purposes. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a post-processor installation system for a large tractor. The main post-processor bracket connects the cab, the gearbox and the engine through the first post-processor auxiliary bracket and the second post-processor auxiliary bracket. Not only does it have better connection stability in all directions, greatly improving the structural strength of the main post-processor bracket, but also the stability after the post-processor is installed makes the integration degree of the main post-processor bracket assembly higher and the assembly complexity smaller. The setting of the reinforcing ribs can effectively ensure that the main post-processor bracket has stronger structural strength on the basis of a smaller volume, greatly reducing the weight and the occupied space of the main post-processor bracket. Therefore, the layout difficulty of the whole machine is effectively reduced.
[0005] The above technical purpose of the utility model is achieved through the following technical solutions:
[0006] A post-processor installation system for a large tractor includes a main post-processor bracket for connecting with the cab floor and the gearbox, a first post-processor auxiliary bracket for connecting with the engine, and a second post-processor auxiliary bracket for transitional connection between the main post-processor bracket and the first post-processor auxiliary bracket.
[0007] By adopting the above technical solution, the main support of the post-processor connects the cab, the gearbox, and the engine through the first auxiliary support of the post-processor and the second auxiliary support of the post-processor, making the connection stability in all directions better, greatly improving the structural strength of the main support of the post-processor and the stability after the post-processor is installed.
[0008] A further setting of the present utility model is that: the main support of the post-processor is welded by a post-processor support plate, multiple reinforcing ribs, and a cab support. One side of the post-processor support plate is bent downward to form a gearbox connecting plate fixedly connected to the gearbox. The reinforcing ribs are located below the post-processor support plate and are respectively fixedly connected to the post-processor support plate and the gearbox connecting plate. The cab support is located above the post-processor support plate.
[0009] By adopting the above technical solution, the main support of the post-processor supports and fixes the post-processor through the post-processor support plate, connects with the cab floor through the cab support on the post-processor support plate, and connects with the gearbox through the gearbox connecting plate, thereby realizing the connection of the cab, the gearbox, and the engine, making the integration degree of the assembly of the main support of the post-processor higher, the assembly complexity smaller. The setting of the reinforcing ribs can effectively ensure that the main support of the post-processor has stronger structural strength on the basis of a smaller volume, greatly reducing the weight and occupied space of the main support of the post-processor, and thus effectively reducing the layout difficulty of the whole machine.
[0010] A further setting of the present utility model is that: the reinforcing ribs include transverse rib plates and longitudinal rib plates, and the transverse rib plates and the longitudinal rib plates are arranged in an intersecting manner.
[0011] By adopting the above technical solution, the reinforcing ribs are arranged in an intersecting manner by the transverse rib plates and the longitudinal rib plates, further increasing the structural strength of the main support of the post-processor, making the bearing capacity of the main support of the post-processor stronger and the service life longer.
[0012] A further setting of the present utility model is that: one side of the post-processor support plate is fixedly connected to the post-processor, and a toolbox mounting hole is reserved on the other side of the post-processor support plate.
[0013] By adopting the above technical solution, the reserved toolbox mounting hole can be used to install a toolbox, making full use of the extra space.
[0014] A further setting of the present utility model is that: the cab support on the main support of the post-processor is connected to the mounting hole on the cab floor through bolts.
[0015] A further setting of the present utility model is that one end of the first post-processor auxiliary bracket is connected to the engine by bolts, the other end of the first post-processor auxiliary bracket is connected to one end of the second post-processor auxiliary bracket by bolts, and the other end of the second post-processor auxiliary bracket is connected to the main post-processor bracket by bolts.
[0016] By adopting the above technical solution, the second post-processor auxiliary bracket can fix the pipelines and wire harnesses connecting the post-processor and the engine through cable ties, maximizing the utilization of space resources. Moreover, the bolt connection method is simple in the processes of machining, assembly and disassembly, convenient to operate, low in manufacturing cost and good in fixing effect.
[0017] A further setting of the present utility model is that shock-absorbing mechanisms are respectively arranged on the post-processor support plate of the main post-processor bracket, the transmission connection plate and the support surface where the first post-processor auxiliary bracket is connected to the engine. The shock-absorbing mechanism includes a plurality of arc-shaped shock-absorbing plates, and each arc-shaped shock-absorbing plate is equidistantly arranged and respectively embedded in the installation groove on the support surface. The outer arc surface of the arc-shaped shock-absorbing plate abuts against the base of the post-processor, the outer wall of the transmission or the engine, both ends of the arc-shaped shock-absorbing plate respectively abut against the bottom wall of the installation groove, and the width of the arc-shaped shock-absorbing plate is slightly smaller than the width of the installation groove.
[0018] By adopting the above technical solution, the setting of the shock-absorbing mechanism can effectively eliminate the influence of the vibrations generated during the operation of the post-processor, the cab, the transmission and the engine on the main post-processor bracket, making the service life of the main post-processor bracket longer. At the same time, it can also greatly reduce the mutual influence of the vibrations generated by the cab, the transmission and the engine during operation, thereby indirectly improving the service life of mechanical components such as the cab, the transmission and the engine. When the arc-shaped shock-absorbing plate is subjected to vibrations, its elastic deformation is used to buffer the vibrations, reducing the impact of the vibrations on the post-processor bracket, so as to achieve the shock-absorbing effect.
[0019] A further setting of the present utility model is that the arc-shaped shock-absorbing plate is made of an elastic metal material with good heat conduction, and both ends of the installation groove penetrate through.
[0020] By adopting the above technical solution, the arc-shaped shock-absorbing plate is made of an elastic metal material with good heat conduction, so that when it is pressed against the base of the after-treatment device, the outer walls of the gearbox and the engine, it can exchange heat with the base of the after-treatment device and the outer walls of the gearbox, transferring the heat generated during the operation of the after-treatment device, the gearbox and the engine to the arc-shaped shock-absorbing plate. During the reciprocating vibration process of the arc-shaped shock-absorbing plate, deformation occurs, causing the space between the inner arc surface of the arc-shaped shock-absorbing plate and the bottom of the installation groove to increase or decrease. As a result, external air repeatedly enters or exits through both ends of the installation groove, and continuously takes away the heat on the arc-shaped shock-absorbing plate during the process of repeatedly entering or exiting the space between the inner arc surface of the arc-shaped shock-absorbing plate and the bottom of the installation groove, thereby achieving the effect of cooling the after-treatment device and the gearbox.
[0021] The beneficial effects of the present utility model are as follows:
[0022] 1. In the present utility model, the main support of the after-treatment device connects the cab, the gearbox, and the engine together through the first auxiliary support and the second auxiliary support of the after-treatment device, making its connection stability in all directions better, greatly improving the structural strength of the main support of the after-treatment device and the stability after the installation of the after-treatment device.
[0023] 2. In the present utility model, the main support of the after-treatment device supports and fixes the after-treatment device through the support plate of the after-treatment device. It is connected to the cab floor through the cab support on the support plate of the after-treatment device and connected to the gearbox through the gearbox connecting plate, thereby realizing the connection of the cab, the gearbox, and the engine. This makes the integration degree of the assembly of the main support of the after-treatment device higher, the complexity of the assembly smaller. The setting of the reinforcing ribs can effectively ensure that the main support of the after-treatment device has stronger structural strength on the basis of a smaller volume, greatly reducing the weight and the occupied space of the main support of the after-treatment device. Therefore, the layout difficulty of the whole machine is effectively reduced.
[0024] 3. In the present utility model, the reinforcing ribs are arranged by the cross-interleaving of the transverse rib plates and the longitudinal rib plates, further increasing the structural strength of the main support of the after-treatment device, making the bearing capacity of the main support of the after-treatment device stronger and the service life longer.
[0025] 4. The toolbox installation holes reserved on the other side of the support plate of the after-treatment device in the present utility model can be used to install a toolbox, making full use of the redundant space.
[0026] 5. In the present utility model, the second auxiliary support of the after-treatment device can fix the pipelines and wire harnesses connecting the after-treatment device and the engine through cable ties, maximizing the utilization of space resources. Moreover, the bolt connection method has a simple process of processing, assembly and disassembly, convenient operation, low manufacturing cost and good fixing effect.
[0027] 6. The setting of the shock absorption mechanism in the present utility model can effectively eliminate the influence of vibrations generated during the operation of the post-processor, cab, gearbox, and engine on the main bracket of the post-processor, making the service life of the main bracket of the post-processor longer. At the same time, it can also greatly reduce the mutual influence of the vibrations generated by the cab, gearbox, and engine during operation. Thus, the service life of mechanical components such as the cab, gearbox, and engine is indirectly improved. When the arc-shaped shock absorption plate is subjected to vibrations, it uses its elastic deformation to buffer the vibrations, reducing the impact of the vibrations on the post-processor bracket, and thus achieving the shock absorption effect.
[0028] 7. The arc-shaped shock absorption plate in the shock absorption mechanism of the present utility model is made of an elastic metal material with good heat conduction. When it is tightly pressed against the base of the post-processor, the outer walls of the gearbox and the engine, heat exchange can occur between it and the base of the post-processor and the outer walls of the gearbox, causing the heat generated during the operation of the post-processor, gearbox, and engine to be transferred to the arc-shaped shock absorption plate. During the reciprocating vibration process of the arc-shaped shock absorption plate, deformation occurs, causing the space between the inner arc surface of the arc-shaped shock absorption plate and the bottom of the installation groove to increase or decrease. As a result, external air repeatedly enters or exits through both ends of the installation groove. During the process of the external air repeatedly entering or exiting the space between the inner arc surface of the arc-shaped shock absorption plate and the bottom of the installation groove, the heat on the arc-shaped shock absorption plate is continuously carried away, thus achieving the effect of cooling the post-processor and the gearbox.

[0037] Furthermore, the main support bracket 2 of the post-processor is welded by a support plate 201 of the post-processor, multiple reinforcing ribs 202, and a cab support 203. One side of the support plate 201 of the post-processor is bent downward to form a transmission connecting plate 204 for fixedly connecting with the transmission 1.

[0040] Furthermore, the cab support 203 on the main support bracket 2 of the post-processor is connected with the cab floor 8 by bolts.

[0042] Further, shock-absorbing mechanisms 9 are respectively provided on the post-processor support plates 201, the transmission connection plates 204 of the main post-processor bracket 2, and the support surfaces where the first post-processor auxiliary bracket 4 is connected to the engine 3. The shock-absorbing mechanisms 9 include a plurality of arc-shaped shock-absorbing plates 901. Each of the arc-shaped shock-absorbing plates 901 is equidistantly arranged and respectively embedded in the installation grooves 902 on the support surface. The outer arc surface of the arc-shaped shock-absorbing plate 901 abuts against the base of the post-processor 6, the outer wall of the transmission 1 or the engine 3. The two ends of the arc-shaped shock-absorbing plate 901 respectively abut against the bottom wall of the installation groove 902. The width of the arc-shaped shock-absorbing plate 901 is slightly smaller than the width of the installation groove 902.
[0043] Further, the arc-shaped shock-absorbing plate 901 is made of an elastic metal material with good heat conduction, and both ends of the installation groove 902 penetrate through.
[0044] The working principle of the present utility model: The main post-processor bracket 2 connects the cab, the transmission 1, and the engine 3 together through the first post-processor auxiliary bracket 4 and the second post-processor auxiliary bracket 5, making the connection stability in all directions better, greatly improving the structural strength of the main post-processor bracket 2 and the stability after the post-processor 6 is installed;
[0045] The main post-processor bracket 2 supports and fixes the post-processor 6 through the post-processor support plate 201, connects to the cab floor 8 through the cab support 203 on the post-processor support plate 201, and connects to the transmission 1 through the transmission connection plate 204, thereby realizing the connection of the cab, the transmission 1, and the engine 3, making the integration degree of the assembly of the main post-processor bracket 2 higher and the assembly complexity smaller;
[0046] The setting of the reinforcing ribs 202 can effectively ensure that the main post-processor bracket 2 has stronger structural strength on the basis of a smaller volume, greatly reducing the weight and occupied space of the main post-processor bracket 2. Therefore, the layout difficulty of the whole machine is effectively reduced. The reinforcing ribs 202 are formed by the cross-intersection of transverse rib plates and longitudinal rib plates, further increasing the structural strength of the main post-processor bracket 2, making the bearing capacity of the main post-processor bracket 2 stronger and the service life longer;
[0047] The toolbox installation holes 7 reserved on the other side of the post-processor support plate 201 can be used to install the toolbox, making full use of the redundant space;
[0048] The post-processor auxiliary bracket II 5 can fix the pipelines and wire harnesses connecting the post-processor 6 and the engine 3 through cable ties, maximizing the utilization of space resources. Moreover, the bolt connection method is simple in the processes of machining, assembly and disassembly, convenient to operate, low in manufacturing cost and good in fixing effect;
[0049] The setting of the shock absorption mechanism 9 can effectively eliminate the influence of the vibrations generated during the operation of the post-processor 6, the cab, the gearbox 1 and the engine 3 on the post-processor main bracket 2, making the service life of the post-processor main bracket 2 longer. At the same time, it can also greatly reduce the influence of the vibrations generated by the cab, the gearbox 1 and the engine 3 on each other during operation, thereby indirectly increasing the service life of mechanical components such as the cab, the gearbox 1 and the engine 3. When the arc-shaped shock absorption plate 901 is subjected to vibrations, its elastic deformation is used to buffer the vibrations, reducing the impact of the vibrations on the post-processor 6 bracket, thus achieving the shock absorption effect;
[0050] The arc-shaped shock absorption plate 901 in the shock absorption mechanism 9 is made of an elastic metal material with good heat conduction, so that when it is in tight contact with the base of the post-processor 6, the outer walls of the gearbox 1 and the engine 3, heat exchange can occur with the base of the post-processor 6 and the outer walls of the gearbox 1, transferring the heat generated during the operation of the post-processor 6, the gearbox 1 and the engine 3 to the arc-shaped shock absorption plate 901. The arc-shaped shock absorption plate 901 deforms during the reciprocating vibration process, causing the space between the inner arc surface of the arc-shaped shock absorption plate 901 and the bottom of the installation groove 902 to increase or decrease, so that external air repeatedly enters or exits through both ends of the installation groove 902. During the process of the external air repeatedly entering or exiting the space between the inner arc surface of the arc-shaped shock absorption plate 901 and the bottom of the installation groove 902, the heat on the arc-shaped shock absorption plate 901 is continuously taken away, thus achieving the effect of cooling the post-processor 6 and the gearbox 1.
