DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model. Figures 1-7 A commercial vehicle engine transmission assembly support device, (such as

[0029] , Figure 1 , Figure 2 ​​​As shown in the figure) including support platform assembly 1, front support base assembly 2, front support frame assembly 3, rear support base fixed plate 4 and rear support assembly 5. The upper end surface of the support platform assembly 1 is fixedly installed on one side of the center of the front support base assembly 2. The top of the front support base assembly 2 is adjustably fixedly installed on the front support frame assembly 3. The upper end surface of the support platform assembly 1 is slidably installed on the other side of the center of the rear support assembly 5. The top of the rear support base fixed plate 4 is provided with the rear support assembly 5. The top of the front support frame assembly 3 and the rear support assembly 5 are respectively centered and adapted to support the engine transmission assembly of the commercial vehicle. By adjusting the height, the support of the engine transmission assembly with different height differences is satisfied; by adjusting the distance between the front support frame assembly 3 and the rear support assembly 5, the support of the engine transmission assembly with different lengths is satisfied, and the general support demand is satisfied.

[0030] In the above embodiment, as a further improvement of the utility model: (as Figure 1 As shown in the figure) the upper end bearing surface of the front support frame assembly 3 and the rear support assembly 5 is respectively provided with a pad 6. The pad 6 is used to buffer the support of the engine transmission assembly.

[0031] In the above embodiment, as a preferred technical scheme of the utility model: the pad 6 is a polyurethane pad; the pad 6 is fastened and installed using a counterbore bolt. The polyurethane pad has very high wear resistance, and its wear resistance is 3-5 times that of general rubber, which enables it to maintain good performance during long-term use. The polyurethane pad also has good durability and can withstand long-term alternating loads without delamination, thereby prolonging the service life. The hardness range of the polyurethane pad is wide, from Shore A10 to Shore A95 (or even higher), which can be selected according to specific needs. At high hardness, the polyurethane pad still has the elongation and resilience of rubber, and its impact strength and bending strength are much higher than those of plastic. The tensile strength and tear resistance of the polyurethane pad are also high, and it can withstand large external forces without being easily damaged. The polyurethane pad has good resilience and can quickly return to its original shape, thereby effectively buffering. The polyurethane pad has excellent chemical corrosion resistance and can resist the invasion of various chemicals. At the same time, it also has good aging resistance and can maintain good performance stability during long-term use. The polyurethane pad has excellent shock absorption and damping performance, and can effectively absorb and disperse the vibration and impact energy under external force.

[0032] The countersunk bolt design of the polyurethane pad allows the bolt head to sink into the hole of the pad or component, flush with or slightly lower than the surface, thereby avoiding the protrusion of the bolt head and simplifying the installation process; this design not only improves installation efficiency, but also ensures installation accuracy, because the bolt tightening process can be more direct and stable. The countersunk bolt forms a tight fit between the pad and the component through precise hole depth and hole diameter design; this tight fit can effectively prevent the bolt from loosening or falling off during use, thereby enhancing the stability and durability of the structure; especially under heavy loads or vibration loads, the countersunk bolt fastening installation can provide a more reliable connection effect. Since the head of the countersunk bolt does not protrude from the pad 6 or the surface of the component, the space can be maximized. The design of the countersunk bolt fastening installation makes the maintenance and replacement process easier.

When bearing external load, reinforcing support structure 3.2 can effectively disperse the pressure, reduce the risk of single-point overload, thereby preventing the deformation of Y type front support frame assembly 3. By increasing reinforcing support structure 3.2, the carrying capacity of Y type front support frame assembly 3 is significantly improved. The design of reinforcing support structure 3.2 can also optimize the stress distribution of Y type front support frame assembly 3. The addition of reinforcing support structure 3.2 also improves the overall rigidity of Y type front support frame assembly 3. The setting of reinforcing support structure 3.2 also helps to prolong the service life of Y type front support frame assembly 3;Due to the improvement of the stability and carrying capacity of the structure, Y type front support frame assembly 3 can better resist fatigue and wear during long-term use, thereby reducing the maintenance and replacement cost caused by deformation.

The rear support base fixing plate 4 is connected with the support platform assembly 1 through the flat base 4.1, which makes the whole structure more compact and stable. The flat base 4.1 provides a wide contact area, enhancing the connection strength with the support platform assembly 1. The design of the flat base 4.1 enables the pressure to be more evenly distributed on the entire contact surface, thereby reducing the risk of single-point overload; this pressure dispersion effect helps to improve the carrying capacity of the entire structure. As a key component of connection, the fastener 4.2 can firmly connect the rear support base fixing plate 4 with the support platform assembly 1 together, ensuring that it will not loosen or deform when bearing heavy load. Through the design of flat base 4.1 and fastener 4.2, the installation process is simplified, and the user only needs to place the flat base 4.1 at the appropriate position of the support platform assembly 1 and use the fastener 4.2 to fix it, which is not only convenient and fast, but also can ensure the firmness and stability of the connection.
