DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 The utility model provides a shock-absorbing bushing for an automobile suspension, comprising a bushing assembly 100 and a shock-absorbing assembly 200;

[0023] The bushing assembly 100 includes an outer bushing 101, the inner wall of the outer bushing 101 is provided with two arc-shaped convex ridges 102, a sleeve 103 is installed inside the outer bushing 101, a plurality of T-shaped bars 104 are fixedly connected to the side surface of the sleeve 103, and a mounting plate 105 is fixedly connected to the upper end of the sleeve 103;

[0024] The shock absorbing assembly 200 includes a shock absorbing sleeve 201 installed inside the outer sleeve 101, arc-shaped grooves 202 are provided on both sides of the shock absorbing sleeve 201, the arc-shaped ridges 102 are clamped inside the arc-shaped grooves 202, a plug-in hole 203 is provided inside the shock absorbing sleeve 201, and a plurality of T-shaped grooves 204 are provided on the inner wall of the plug-in hole 203, an installation groove 205 is provided at the upper end of the shock absorbing sleeve 201, a plurality of anti-slip ridges 206 are provided on the side surface of the shock absorbing sleeve 201, and the installation plate 105 is clamped inside the installation groove 205.

[0025] In a specific embodiment, the bushing assembly 100 cooperates with the shock absorbing assembly 200 to not only achieve a dead angle shock absorbing effect on the suspension connecting rod, thereby enhancing the shock absorbing effect, but also the above-mentioned structures cooperate with each other to replace the shock absorbing sleeve 201 when it is worn, avoiding discarding the outer bushing 101 and the sleeve 103, thereby reducing cost losses. When the suspension connecting rod is vibrated, the vibration is transmitted to the rubber shock absorbing sleeve 201, and the rubber shock absorbing sleeve 201 can reduce the vibration force on the suspension connecting rod, thereby achieving a shock absorbing effect. At the same time, the arcuate convex ridge 102 is clamped in the arcuate groove 202, and the shock absorbing sleeve 201 can be limited by the outer bushing 101 to avoid rotation and weakening of the shock absorbing effect. The T-shaped bar 104 is clamped in the T-shaped groove 204 to further limit the sleeve 103, and the semicircular rib 121 is clamped in the semicircular groove 221 to connect the outer bushing 101, the shock-absorbing sleeve 201 and the sleeve 103 as a whole, thereby significantly enhancing the shock-absorbing effect of the bushing. When the shock-absorbing sleeve 201 is worn out due to long-term use, the mounting plate 105 and the sleeve 103 are first removed from the mounting groove 205 and the plug-in hole 203 respectively. At this time, the T-shaped bar 104 is removed from the T-shaped groove 204, and then the arc-shaped rib 102 is removed from the arc-shaped groove 202. Therefore, the outer bushing 101 and the sleeve 103 can be disassembled, and then the shock-absorbing sleeve 201 can be disassembled and replaced without discarding the outer bushing 101 and the sleeve 103, thereby reducing cost losses.

[0026] See also Figure 2 and Figure 3 The lower end of the outer bushing 101 is fixedly connected to a limiting ring 111 , and the inner wall of the limiting ring 111 is fixedly connected to a plurality of limiting blocks 112 .

[0027] In a specific embodiment, the limiting ring 111 cooperates with the limiting block 112 to not only support the shock-absorbing sleeve 201 , but also limit the position of the shock-absorbing sleeve 201 , thereby enhancing the shock-absorbing effect of the shock-absorbing sleeve 201 .

[0028] See also Figure 2 and Figure 3 A plurality of semicircular ribs 121 are fixedly connected to the upper end of the mounting plate 105 .

[0029] In a specific embodiment, the semicircular ribs 121 cooperate with the mounting plate 105 to further play a limiting role, thereby preventing the shock-absorbing sleeve 201 from rotating during shock absorption and reducing the shock-absorbing effect.

[0030] See also Figure 2-Figure 5 A protrusion 211 is fixedly connected to the lower end of the shock absorbing sleeve 201 , and a plurality of limiting grooves 212 are formed on the side surface of the protrusion 211 . The protrusion 211 is clamped in the interior of the limiting ring 111 , and the plurality of limiting blocks 112 are clamped in the interior of the limiting grooves 212 .

[0031] In a specific embodiment, the protrusion 211 is clamped in the limiting ring 111, and the limiting block 112 is clamped in the limiting groove 212, so that the shock-absorbing sleeve 201 can be limited and the protrusion 211 can be easily disassembled as needed.

[0032] See also Figure 4 and Figure 5 The inner wall of the installation groove 205 is provided with a plurality of semicircular grooves 221 , and the plurality of semicircular ridges 121 are all snap-fitted into the interior of the semicircular grooves 221 .

[0033] In a specific embodiment, the semicircular rib 121 is snapped into the semicircular groove 221, so that it can be connected through the shock-absorbing sleeve 201 and the mounting plate 105, and the sleeve 103 can be disassembled by taking out the semicircular rib 121.

[0034] See also Figure 2-Figure 5 The outer bushing 101, the sleeve 103 and the mounting plate 105 are all made of low carbon steel, and the shock absorbing sleeve 201 is made of rubber.

[0035] In a specific embodiment, the outer bushing 101, sleeve 103 and mounting plate 105 made of low carbon steel can enhance their own strength and the friction with the shock-absorbing sleeve 201. The shock-absorbing sleeve 201 made of rubber can significantly enhance the shock-absorbing effect of the shock-absorbing bushing.

[0036] Working principle: When in use, when the suspension connecting rod is vibrated, the vibration is transmitted to the rubber shock-absorbing sleeve 201. The rubber shock-absorbing sleeve 201 can reduce the vibration force on the suspension connecting rod, thereby achieving a shock-absorbing effect. At the same time, the arc-shaped convex rib 102 is clamped in the arc-shaped groove 202, and the shock-absorbing sleeve 201 can be limited by the outer bushing 101 to avoid rotation and weakening of the shock-absorbing effect. At the same time, the T-shaped bar 104 is clamped in the T-shaped groove 204 to further limit the sleeve 103, and the semi-circular rib 121 is clamped in the semi-circular groove 221 to enable the outer bushing 101 , the shock-absorbing sleeve 201 and the sleeve 103 are connected as a whole, thereby significantly enhancing the shock-absorbing effect of the sleeve. When the shock-absorbing sleeve 201 is worn out after long-term use, firstly, the mounting plate 105 and the sleeve 103 are taken out from the mounting groove 205 and the plug-in hole 203 respectively. At this time, the T-shaped bar 104 is taken out from the T-shaped groove 204, and then the arc-shaped convex ridge 102 is taken out from the arc-shaped groove 202. Therefore, the outer sleeve 101 and the sleeve 103 can be disassembled, so that the shock-absorbing sleeve 201 can be disassembled and replaced without discarding the outer sleeve 101 and the sleeve 103, thereby reducing cost losses.
