[0018] EMBODIMENT

[0019] As Figure 1 and Figure 2As shown, the hydraulic suspension structure of the vehicle body includes a mirror-arranged upper vulcanized metal frame 1 and a lower vulcanized metal frame 6, as well as an upper vulcanized seal 2 and a lower vulcanized seal 7. The upper vulcanized metal frame 1 and the upper vulcanized seal 2 are interference fit, and the lower vulcanized metal frame 6 and the lower vulcanized seal 7 are interference fit. The upper vulcanized metal frame 1 and the lower vulcanized metal frame 6 are connected by a circular vulcanized rubber 3. The outer ring of the lower vulcanized metal frame 6 is fixed with a circular vulcanized frame 4. The inner rings of the upper vulcanized seal 2 and the lower vulcanized seal 7 are fixed with an upper inner tube 5 and a lower inner tube 8 respectively, and the inner ring of the lower inner tube 8 is fixed with a connecting seat 9.

[0020] Specifically, the upper vulcanized part metal skeleton 1, the upper vulcanized seal 2, the circular vulcanized rubber 3, the lower vulcanized part metal skeleton 6 and the lower vulcanized seal 7 are all formed by vulcanization of aluminum and rubber. First, the upper vulcanized seal 2 and the lower vulcanized seal 7 are pressed into the inside of the circular vulcanized rubber 3 and the circular vulcanized skeleton 4 respectively, and then the upper vulcanized part metal skeleton 1 and the lower vulcanized part metal skeleton 6 are pressed into the outer rings of the upper vulcanized seal 2 and the lower vulcanized seal 7 respectively. After pressing, the damping liquid seal is achieved to meet the performance, and the process is simple, the cost is low, the utilization rate is high, and the size is easy to control, so that the product has good vibration reduction and vibration isolation performance, while saving customers a lot of costs and improving customer satisfaction.

[0021] like Figure 2 As shown, a mounting groove 31 is provided on the side of the circular vulcanized rubber 3 close to the circular vulcanized skeleton 4 , and an inner concave portion 21 which is interference-fitted with the mounting groove 31 is provided on the side of the upper vulcanized seal 2 away from the upper inner tube 5 .

[0022] Specifically, the cross-section of the circular vulcanized rubber 3 is in the shape of an "I", and the cross-section of the inner concave portion 21 is in the shape of a "J". When the upper vulcanized metal skeleton 1 is inserted between the upper vulcanized seal 2 and the inner concave portion 21, the inner concave portion 21 will be squeezed to fit tightly with the circular vulcanized rubber 3 and the circular vulcanized skeleton 4 to ensure airtightness.

[0023] like Figure 2 As shown, the inner concave portion 21 extends from one side of the upper vulcanized seal 2 to the inner wall of the circular vulcanized skeleton 4 and is made of elastic material.

[0024] Specifically, the elastic material is preferably rubber, the front end of the inner concave portion 21 is 5mm thick with a rubber wall thickness of 0.3mm, and a protrusion is provided at the lower end. The protrusion increases the friction between the inner concave portion 21 and the assembly groove 31, making it difficult to fall off.

[0025] like Figure 1 and Figure 2As shown, the upper vulcanization part metal framework 1 is inserted into the inner recess one 21, and the upper vulcanization part metal framework 1 is provided with the pressing part one 11 and the pressing part two 12, both of which are offset in the direction away from each other and are in contact with the upper vulcanization sealing part 2 and the inner recess one 21 respectively.

[0026] Specifically, the upper vulcanization part metal framework 1 is semi-enclosed in the upper vulcanization sealing part 2 and the inner recess one 21, and the offset of the pressing part one 11 and the pressing part two 12 is tightly attached to the side wall of the upper vulcanization sealing part 2 and the inner recess one 21, which is used to push the inner recess one 21 to the side wall of the assembly groove 31 and the circular vulcanization framework 4, further increasing the sealing performance.

[0027] As shown, Figure 2 The lower vulcanization sealing part 7 is provided with the inner recess two 71 which is in interference fit with the assembly groove 31 away from the lower inner tube 8, the inner recess two 71 extends to the inner wall of the circular vulcanization framework 4 away from the lower vulcanization sealing part 7, and is made of elastic material.

[0028] Specifically, the cross section of the inner recess two 71 is in the shape of "Ji" character, and when the lower vulcanization part metal framework 6 is inserted between the lower vulcanization sealing part 7 and the inner recess two 71, it will extrude the inner recess two 71 to be tightly attached to the circular vulcanization rubber 3 and the circular vulcanization framework 4, ensuring the airtightness, the elastic material is preferably rubber, the rubber wall thickness of the inner recess two 71 is 0.3mm in the front 5mm, and the lower end is provided with a protrusion which will increase the friction between the assembly groove 31 and the inner recess two 71, so that it is not easy to fall off

[0029] As shown, Figure 1 and Figure 2 The lower vulcanization part metal framework 6 is inserted into the inner recess two 71, and the lower vulcanization part metal framework 6 is provided with the pressing part three 61 and the pressing part four 62, both of which are offset in the direction away from each other and are in contact with the lower vulcanization sealing part 7 and the inner recess two 71 respectively.

[0030] Specifically, the lower vulcanization part metal framework 6 is semi-enclosed in the lower vulcanization sealing part 7 and the inner recess two 71, and the offset of the pressing part three 61 and the pressing part four 62 is tightly attached to the side wall of the lower vulcanization sealing part 7 and the inner recess two 71, which is used to push the inner recess two 71 to the side wall of the assembly groove 31 and the circular vulcanization framework 4, further increasing the sealing performance.

[0031] The above examples are only used to illustrate the technical solutions of the present application, but not to limit it.
