Description

Technical Field

[0001] This utility model relates to the field of vehicle manufacturing technology, and in particular to a shock-absorbing structure for mounting a vehicle muffler. Background Technology

[0002] Vehicle mufflers are typically installed using shock-absorbing pads. Commercial vehicles, especially buses, usually have a separate compartment on the rear frame for the muffler. The muffler is usually installed low within this compartment, using clamps, shock-absorbing pads, and long hexagonal head bolts. However, due to the structural limitations of the clamps, the operating space for tightening the long hexagonal head bolts is limited, making it difficult to reach a wrench and requiring considerable effort from the worker. In contrast, there is more operating space above the muffler, making it easier to access the nuts on the upper part of the long hexagonal head bolts.

[0003] While the issue can be partially resolved by first securing the clamps and then installing the muffler, after installation, the muffler's position often needs to be readjusted due to piping issues, requiring the disassembly of the shock-absorbing components. At this point, inserting a wrench into the hexagonal head of the long hexagonal bolt inside the clamps becomes quite difficult, and this problem also exists during subsequent vehicle aftertreatment maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide a shock-absorbing structure for vehicle muffler installation that is easy to install and disassemble.

[0005] This utility model is achieved through the following measures: A vibration damping structure for mounting a vehicle muffler is characterized by comprising several sets of bracket plates mounted on a vehicle frame, wherein the bracket plates are provided with clamps for mounting the muffler via several sets of vibration damping components, and typically there are two sets of bracket plates and clamps. The clamp includes a hoop and a U-shaped mounting plate disposed on the hoop. The hoop is a plate formed into a circular structure, and both ends of the plate are provided with ear plates with through holes. The hoop surrounds the outside of the muffler and is tightened and fixed by bolts on the two ear plates. The U-shaped mounting plate is provided with several sets of through mounting holes, usually two sets of mounting holes. The bracket plate is provided with several sets of waist-shaped holes that cooperate with the mounting holes, usually two sets of waist-shaped holes. The waist-shaped holes are used to facilitate the adjustment of the position of the muffler. The vibration damping assembly includes a pair of rubber damping pads and a long hexagonal head bolt. The pair of rubber damping pads are respectively disposed on both sides of the bracket plate. The long hexagonal head bolt passes through the mounting hole, one side of the rubber damping pad, the waist-shaped hole and the other side of the U-shaped mounting plate from the bottom upwards, and is then fixed with a nut.

[0006] The specific features of this utility model also include: The U-shaped mounting plate has a Z-shaped plate on its lower side facing the hoop, which is used to cooperate with the long hexagonal head bolt. The middle groove of the Z-shaped plate cooperates with the two parallel sides of the hexagonal head of the long hexagonal head bolt, that is, the two parallel sides of the hexagonal head are stuck in the middle groove of the Z-shaped plate.

[0007] Both sides of the Z-shaped plate are provided with protrusions, which serve to raise the plate so that it can avoid the washers located around the long hexagonal head bolts. The boss is provided with a round hole for the corresponding bolt to pass through. The U-shaped mounting plate on both sides of the mounting hole is provided with a threaded hole that mates with the corresponding bolt. The Z-shaped plate is fixed to the lower side of the U-shaped mounting plate by a bolt structure. Before installing the muffler, first install the washers on the long hexagonal head bolts and pass them upwards through the mounting holes from the lower side of the U-shaped mounting plate. Then install the corresponding Z-shaped plates, so that the middle groove of the Z-shaped plates can hold the hexagonal head of the long hexagonal head bolts, and fix the Z-shaped plates with the corresponding bolts. Then install the clamps and rubber vibration damping pads onto the bracket plate. The corresponding nuts can then be installed on the long hexagonal head bolts from above. Finally, install the muffler. In this way, the position of the muffler can be adjusted by removing the nuts on the long hexagonal head bolts without removing the muffler. Since the space above the muffler is generally relatively large, it is convenient to operate.

[0008] T-shaped grooves are provided on the lower side of the U-shaped mounting plate on both sides of the mounting hole. One end of the T-shaped groove passes through one side of the U-shaped mounting plate. T-shaped sliders that slide with the T-shaped grooves are provided on the protrusions on both sides of the zigzag plate. A pair of mounting grooves are provided on the corresponding sides of the U-shaped mounting plate. Guide holes that pass through to the T-shaped sliding grooves on the corresponding sides of the mounting grooves are provided on the corresponding sides of the mounting grooves. A matching sliding plate is slidably disposed in the mounting groove. A round rod that mates with the guide hole is provided on the sliding plate. The round rod passes through the guide hole and extends into the T-shaped sliding groove on the corresponding side. An insertion hole that mates with the round rod is provided on the corresponding side of the T-shaped sliding plate.

[0009] A spring is provided between the sliding plate and the corresponding side of the mounting groove. One end of the spring is fixed to the sliding plate, and the other end of the spring is fixed to the corresponding side of the mounting groove. Under the action of the spring, the free end of the round rod is inserted into the insertion hole on the corresponding side, thereby fixing the Z-shaped plate.

[0010] The free end of the slide plate extends out of the mounting slot. By manually sliding the slide plate, the round rod can slide out of the insertion hole, thus releasing the fixation of the Z-shaped plate.

[0011] Before the muffler is installed, first install the washers on the long hexagonal head bolts and pass them upwards through the mounting holes from the underside of the U-shaped mounting plate. Then, pinch the sliding plates on both sides with your thumb and forefinger to compress the springs and slide them towards the center. Next, slide the Z-shaped plate into the T-shaped groove, so that the middle groove holds the hexagonal head of the long hexagonal head bolt. Then, release your fingers, allowing the round rod to be inserted into the socket under the action of the spring, thus fixing the Z-shaped plate. This method avoids the complexity of bolt installation and also prevents the Z-shaped plate bolts from falling off after long-term vehicle use.

[0012] The beneficial effects of this utility model are as follows: by using the design of the Z-shaped plate to fix the hexagonal head of the long hexagonal head bolt, workers can operate in a larger space above the muffler, which facilitates installation and operation and improves work efficiency.

[0031] The U-shaped mounting plate 5 has a Z-shaped plate 9 on its lower side facing the hoop 4, which is used to cooperate with the long hexagonal head bolt 7.

[0036] Before the muffler 3 is installed, the long hexagonal head bolt 7 is first installed with a washer and then passed upward through the mounting hole from the lower side of the U-shaped mounting plate 5. Then, the sliding plates 13 on both sides are pinched with the thumb and forefinger to compress the spring 12 and slide towards the middle. Then, the Z-shaped plate 9 is slid into the T-shaped groove so that the middle groove 15 locks the hexagonal head 8 of the long hexagonal head bolt 7. Then, the fingers are released so that the round rod 14 is inserted into the socket under the action of the spring 12, thus fixing the Z-shaped plate 9.
