Description

Technical Field

[0001] This utility model relates to the field of commercial vehicle parts technology, specifically a urea tank suspension connection device for commercial vehicles. Background Technology

[0002] Commercial vehicles require urea solution stored in urea tanks for exhaust gas treatment during operation. These tanks are typically fixed to appropriate locations on the vehicle via suspension connections. However, existing urea tank suspension connections for commercial vehicles suffer from several problems: Firstly, the overall structural stability of the suspension connection is poor, and bumps during vehicle operation can easily cause the urea tank to loosen or even detach, affecting the normal operation of the exhaust gas treatment system. Secondly, the support and fixing structure of the urea tank is mostly fixed, making it difficult to adapt to different tank sizes, resulting in poor versatility. Furthermore, installation and disassembly are inconvenient, hindering future maintenance and replacement of the urea tank. Utility Model Content

[0026] Please see Figures 1-4 In this embodiment of the present invention, a urea tank suspension connection device for commercial vehicles includes a suspension connection component 1, which is equipped with an adjustable urea tank support and fixing component 2.

[0027] The suspension connection assembly 1 includes two first U-shaped channel steel bars 11 arranged symmetrically front to back. Two second U-shaped channel steel bars 13 are symmetrically fixedly connected between the two first U-shaped channel steel bars 11 on opposite side walls. An X-shaped reinforcing frame 14 is fixedly connected between the two second U-shaped channel steel bars 13. An installation connection assembly is provided on the rear end of the first U-shaped channel steel bar 11. Through the cooperation of the first U-shaped channel steel bars 11, the second U-shaped channel steel bars 13 and the X-shaped reinforcing frame 14, the overall structural strength and stability of the suspension connection assembly 1 can be improved, providing a stable installation foundation for the urea tank.

[0028] The adjustable urea tank support and fixing assembly 2 includes sliders 24 that are symmetrically slidably installed on the inner side of the first U-shaped channel steel bar 11. An adjustment and fastening assembly is provided between the sliders 24 and the corresponding first U-shaped channel steel bar 11. The top ends of the two sliders 24 on the same side are fixedly connected to the same aluminum alloy support frame 21. The two aluminum alloy support frames 21 are symmetrically arranged, and a urea tank binding assembly is provided between the two aluminum alloy support frames 21. The position of the aluminum alloy support frame 21 can be adjusted by using the adjustment and fastening assembly, thereby adapting to urea tanks of different specifications and enhancing versatility. The urea tank binding assembly can further fix the urea tank and prevent it from shaking.

[0029] The installation connection assembly includes two U-shaped channel steel frames 15 that are symmetrically fixedly connected to the rear end face of the first U-shaped channel steel strip 11 at the rear end; the U-shaped channel steel frames 15 are used to connect with the frame and other structures of commercial vehicles to realize the overall installation of the suspension connection device.

[0030] Two reinforcing rods 16 are horizontally fixedly connected between the two U-shaped channel steel frames 15. The fixed connection between the reinforcing rods 16 and the two U-shaped channel steel frames 15 is by welding. The reinforcing rods 16 can enhance the connection strength between the two U-shaped channel steel frames 15 and improve the stability of the installation connection components.

[0031] The U-shaped channel steel frame 15 is fixedly connected to a triangular mounting base 17 at its rear end. Mounting holes 18 are provided between the front and rear side walls at the three corners of the triangular mounting base 17. Through the mounting holes 18 on the triangular mounting base 17, the device can be securely connected to the commercial vehicle frame using bolts or other fasteners. The triangular structure can also improve the load-bearing capacity and deformation resistance of the mounting base.

[0032] The adjusting fastening assembly includes a fastening bolt 25 fixedly connected to the center of the bottom end of the slider 24. The bottom wall of the first U-shaped channel steel bar 11 has strip grooves 12 at both ends for sliding assembly of the corresponding fastening bolt 25.

The urea tank securing assembly also includes a strap fixing buckle 27 fixedly installed on the other end face of the aluminum alloy support frame 21 on the other side for securing the strap 26 on the corresponding side. After placing the urea tank on the two aluminum alloy support frames 21, the straps 26 are wrapped around the urea tank and inserted into the strap fixing buckle 27 to secure the urea tank. The operation is simple and the fixing effect is good.

[0035] The working principle of this utility model is as follows: During overall installation, the entire device is fixed to the frame of the commercial vehicle using bolts through the mounting holes 18 on the triangular mounting base 17; according to the specifications of the urea tank, the fastening bolts 25 are loosened, and the sliding slider 24 is slid to adjust the distance between the two aluminum alloy support brackets 21. After adjusting to the appropriate position, the fastening bolts 25 are tightened for fixation; the urea tank is placed on the two aluminum alloy support brackets 21, so that the urea tank contacts the anti-slip rubber strip 22, and then the strap 26 is wrapped around the urea tank and inserted into the strap fixing buckle 27 to complete the binding of the urea tank. The entire device is stably connected to the commercial vehicle frame through the suspension connection component 1. The first U-shaped channel steel bar 11, the second U-shaped channel steel bar 13, and the X-shaped reinforcement frame 14 ensure structural strength. In the adjustable urea tank support and fixing component 2, the position of the aluminum alloy support frame 21 can be adjusted by adjusting the fastening component to adapt to different urea tanks. The anti-slip rubber strip 22 of the aluminum alloy support frame 21 increases the friction. The urea tank binding component further fixes the urea tank through the binding strap 26 and the strap fixing buckle 27, thereby achieving stable suspension and fixing of the urea tank and facilitating installation and maintenance.
