[0047] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0048] This utility model relates to a comfort suspension bushing 11, which adopts a conical inner frame 114 vertically arranged inside the outer frame 111, providing vertical stiffness of the suspension bushing 11. The inner frame 114 and the outer frame 111 have buffer gaps at the top and bottom ends, which can absorb vibration and improve comfort. The supporting rubber is located on the inner wall of the outer frame 111 and on the two open inclined sides 1142 of the inner frame 114 on both sides of the inner frame 114 in the X direction (left and right in the figure), which can distribute the vertical load to the X direction, taking into account both vertical vibration reduction and X-direction vibration reduction effects, while ensuring the stiffness in the X direction. The inclined sides 1142 expand the support contact surface of the supporting rubber, avoiding load concentration, and transferring the load of the solid rubber at the top and bottom ends of the conventional bushing to the larger supporting rubber on both sides of the X direction, which has higher durability. The overall structure is simple and has great promotional value.

[0049] A comfort suspension bushing 11, specifically, such as Figure 1-6 As shown, the system includes an outer frame 111, an inner frame 114, and supporting rubber. The outer frame 111 has a ring-shaped structure. The inner frame 114 is vertically positioned inside the outer frame 111, with buffer gaps between it and the upper and lower ends of the outer frame 111. The inner frame 114 has a tapered structure, wider at the top and narrower at the bottom, and has open, inclined sides 1142 on both sides in the X-direction, meaning the bottom of the inclined sides 1142 is closer to the top than the bottom. This provides good vibration damping performance in the X-direction and also distributes the vertical load to the larger supporting rubber on both sides in the X-direction, resulting in higher durability. The inner frame 114 has through-holes. The supporting rubber is positioned between the outer frame 111 and the inner frame 114, and is fixed to the inclined sides 1142 on both sides of the inner frame 114 in the X-direction. The supporting rubber densely fills the gap between the outer frame 111 and the inner frame 114 in the X-direction, improving the X-direction stiffness. When the cab vibrates downwards, the supporting rubber generates a supporting force on the inner frame 114 and deforms to reduce the vibration; when the cab vibrates upwards, the supporting rubber generates a tensile force on the inner frame 114 to reduce the vibration.

[0050] In one embodiment, such as Figure 1As shown, the suspension bushing 11 also includes a central frame 117. The central frame 117 is located in the middle of the support rubber, dividing the support rubber into an inner rubber layer 118 and an outer rubber layer 116. The central frame 117 is fixed to the inner frame 114 and the outer frame 111 through the inner rubber layer 118 and the outer rubber layer 116, respectively. The central frame 117 can be embedded in the support rubber. Preferably, the central frame 117 is located in the middle of the support rubber, completely separating the inner rubber layer 118 and the outer rubber layer 116, that is, the periphery of the central frame 117 is located outside the support rubber, avoiding concentrated stress on the support rubber around the central frame 117 and aggravating wear. The central frame 117 further improves the stiffness of this suspension bushing 11. The central frame 117 supports the inner frame 114 and the outer frame 111 through the inner rubber layer 118 and the outer rubber layer 116, which strengthens the stiffness while ensuring vibration damping performance.

[0051] The suspension bushing 11 also includes a central frame 117, such as Figure 1 As shown, the central frame 117 is a plate-shaped structure adapted to abut against the inclined side 1142. Preferably, the central frame 117 is approximately parallel to the inclined side 1142, which provides good support for the inclined side 1142, can better distribute the load evenly to the supporting rubber, improve the vibration reduction effect, and avoid stress concentration that aggravates the wear of the supporting rubber.

[0052] In a preferred embodiment, such as Figure 1 As shown, the inner wall of the outer frame 111 is provided with a supporting inclined surface 1112 corresponding to the inclined side 1142, and the supporting inclined surface 1112 is approximately parallel to the inclined side 1142.

[0053] In some embodiments, such as Figure 1 As shown, the top surface of the inner frame 114 is provided with an upper limit inner rubber body 119 and / or the bottom surface is fixed with a lower limit inner rubber body 113; including three cases: first, the top surface of the inner frame 114 is provided with an upper limit inner rubber body 119; second, the bottom surface of the inner frame 114 is provided with a lower limit inner rubber body 113; third, the top and bottom surfaces of the inner frame 114 are respectively provided with an upper limit inner rubber body 119 and a lower limit inner rubber body 113. Through the upper limit inner rubber body 119 on the top surface and / or the lower limit inner rubber body 113 on the bottom surface, a certain buffering effect can be provided when the vertical vibration of the cab exceeds the buffering capacity of the X-direction support rubber, further reducing vibration and avoiding rigid collision between the inner frame 114 and the outer frame 111.

[0054] In a further embodiment, such as Figure 1As shown, the bottom surface of the inner frame 114 is provided with a lower limit inner rubber body 113. The lower limit inner rubber body 113 has a U-shaped structure that covers the bottom surface of the inner frame 114 and extends to the two inclined side surfaces 1142, so as to avoid the corners of the bottom of the inner frame 114 rigidly colliding with or wearing down the supporting rubber of the outer frame 111. Preferably, the lower limit inner rubber body 113 is provided on the inner frame 114 so that the bottom surface has a downward protruding arc structure. More preferably, the connection between the bottom surface of the inner frame 114 and the inclined side surfaces 1142 is a rounded chamfer structure to avoid aggravating the wear and tear of the lower limit inner rubber body 113.

[0055] In a preferred embodiment, such as Figure 1 As shown, the top of the inner skeleton 114 has a U-shaped structure, and the upper limit inner rubber body 119 covers the U-shaped top surface of the inner skeleton 114.

[0056] In another embodiment, such as Figure 1 As shown, the inner wall of the top end of the outer frame 111 is provided with an upper limit outer rubber body 120 and / or the inner wall of the bottom end is provided with a lower limit outer rubber body 112, including three cases: first, the inner wall of the top end of the outer frame 111 is provided with an upper limit outer rubber body 120; second, the inner wall of the bottom end of the outer frame 111 is provided with a lower limit outer rubber body 112; and third, the top and bottom ends of the outer frame 111 are respectively provided with an upper limit outer rubber body 120 and a lower limit outer rubber body 112. This is used to provide a certain vibration damping performance vertically and avoid rigid collision between the inner frame 114 and the outer frame 111. Preferably, the upper limit outer rubber body 120 and / or the lower limit rubber body are in the form of an arc-shaped plate structure.

[0057] In a preferred embodiment, such as Figure 1 As shown, the inner frame 114 is provided with an upper limit inner rubber body 119 and a lower limit inner rubber body 113 on its top and bottom sides, respectively. The outer frame 111 is provided with an upper limit outer rubber body 120 and a lower limit outer rubber body 112 at its top and bottom ends, respectively, corresponding to the upper limit inner rubber body 119 and the lower limit inner rubber body 113, to enhance the vertical vibration reduction performance. When the cab vibrates vertically, the vibration is first reduced by the supporting rubber. When the vibration is too large, the upper limit rubber body and the lower limit rubber body will further reduce the vibration until the maximum limit is reached.

[0058] In one embodiment, such as Figure 1-2 As shown, a wear-resistant bushing 115 is provided in the shaft hole of the inner skeleton 114; the wear-resistant bushing 115 is preferably made of polytetrafluoroethylene, which has lubrication-free properties and good wear resistance, thus avoiding noise generation. In a specific embodiment, wear-resistant bushings 115 are respectively provided in both ends of the shaft hole of the inner skeleton 114. When tilted, the two ends of the shaft hole are subjected to greater pressure, thus avoiding noise generation and saving material costs.

[0059] In one embodiment, such as Figure 1-3As shown, the suspension bushing 11 also includes a buffer side pad 12 disposed on the end face of the inner frame 114; preferably, a positioning protrusion 1141 is provided on the end face of the inner frame 114, and a positioning hole is provided on the buffer side pad 12, with the positioning hole of the buffer side pad 12 fitting onto the positioning protrusion 1141. In use, the buffer side pad 12 is disposed on both ends of the inner frame 114, covering the end face of the outer frame 111, and the buffer side pad 12 plays a limiting role in the tilt of the outer frame 111 and the upper suspension when the cab tilts; the positioning protrusion 1141 facilitates the installation and fitting of the buffer side pad 12 on the buffer protrusion.

[0060] When the inner skeleton 114 is provided with an upper limit inner rubber body 119, the positioning protrusion 1141 can be provided on the upper limit inner rubber body 119.

[0061] In a preferred embodiment, such as Figure 1 As shown, the outer frame 111 is provided with an open slot 1111 of a discontinuous annular structure. The open slot 1111 allows the outer frame 111 to have a certain shrinkage capacity, which facilitates interference fit installation on the front suspension bracket assembly. Preferably, the open slot 1111 is provided at the top and / or bottom of the outer frame 111.

[0062] In addition, when the outer frame 111 is provided with an upper limit outer rubber body 120 and / or a lower limit outer rubber body 112, the opening groove 1111 can disconnect the upper limit outer rubber body 120 and / or the lower limit outer rubber body 112.

[0063] Another aspect of this utility model is to provide a vehicle suspension, such as... Figure 3 , Figure 4 and Figure 6 As shown, the system includes an upper front suspension bracket 1 and a lower front suspension bracket 2. The upper front suspension bracket 1 is used to fix the cab and has mounting holes 18. A comfort suspension bushing 11 provided by this invention is installed in the mounting holes 18. The lower front suspension bracket 2 has two opposing front suspension mounting plates 21. Insertion holes 211 are provided on the two front suspension mounting plates 21. The comfort suspension bushing 11 is bolted between the two front suspension mounting plates 21 by its axial ends against the two front suspension mounting plates 21. In actual installation, the front suspension bolt 14 passes through one insertion hole 211, one buffer side washer 12, the shaft hole of the inner frame 114, the other buffer side washer 12, and the other insertion hole 211 in sequence to connect the slotted nut 16. A cotter pin 17 is inserted into the front suspension bolt 14 to prevent the slotted nut 16 from loosening. A washer 15 can be placed between the slotted nut 16 and the mounting plate. By placing the suspension bushing 11 on the upper front suspension bracket 1, the friction between the bushing and the rubber bushing and pin shaft, which is common when the bushing is placed on the lower front suspension bracket 2, is avoided and thus prevents abnormal noise. This ensures the suspension stiffness while providing better vibration reduction performance in the vertical and X directions.

[0064] According to the vehicle suspension provided by this utility model, such as Figure 5-6As shown, the vehicle suspension also includes a lower rear suspension bracket 51, a hydraulic locking plate 52 hinged at one end to the top of the lower rear suspension bracket 51, and a shock absorber 55. The top and bottom ends of the shock absorber 55 are respectively hinged to the bottom end of the lower rear suspension bracket 51 and the other end of the hydraulic locking plate 52 to form a triangular arm structure. The lower rear suspension bracket 51, the hydraulic locking plate 52, the shock absorber, and the upper rear suspension bracket 56 for mounting on the bottom of the cab together constitute the rear suspension assembly 5. The upper rear suspension bracket 56 can be locked in conjunction with the hydraulic locking plate 52. The triangular arm ensures installation strength, and the extension and retraction of the shock absorber 55 ensures vibration damping performance.

[0065] The vehicle suspension also includes a rear lower suspension bracket 51, such as Figure 5 As shown, the hydraulic locking plate 52 has two rear suspension mounting plates 521 forming an inward opening at one end. The rear suspension lower bracket 51 has an upper hinge shaft hole 511 at its top. Convex hinge pads 54 are inserted into both ends of the upper hinge shaft hole 511. The two hinge pads 54 on both sides abut against the two rear suspension mounting plates 521 and are bolted to the hydraulic locking plate 52. The hinge pads 54 are elastic bodies, preferably made of polyurethane material, and use microporous NDI material to effectively eliminate friction noise and allow a certain amount of lateral tilt (X direction in the figure). In actual installation, the section of the convex hinge pad 54 outside the hinge shaft hole abuts against the side of the rear suspension lower bracket 51. The rear suspension bolt passes through the two hinge pads 54 and is bolted to the two rear suspension mounting plates 521. A hydraulic locking sleeve 53 can be sleeved between the rear suspension bolt and the hinge pads 54.

[0066] The suspension connections of this vehicle are highly versatile, allowing for the selection and installation of appropriate components on the chassis and cab based on actual conditions. For example... Figure 7 As shown, the vehicle suspension uses suspension bushings 11 to install front upper suspension brackets 1 and / or front lower suspension brackets 2 of different specifications to adapt to different chassis and cabs, which can connect the cab and chassis while ensuring the suspension height is adapted; similarly, the rear suspension assembly 5 can use the triangular arm structure formed by the rear lower suspension bracket 51, shock absorber 55 and hydraulic locking plate 52 provided by this utility model to adapt to the rear upper suspension bracket 56 of different specifications.

[0067] When the suspension bushing 11 is actually used, the inner frame 114 is provided with an upper limit inner rubber body 119 and a lower limit inner rubber body 113 on the top and bottom sides respectively. The outer frame 111 is provided with an upper limit outer rubber body 120 and a lower limit outer rubber body 112 at both ends of the inner wall. The outer frame 111 is provided with an opening groove 1111 at both ends of the top and bottom. The middle frame 117 fixes the inner frame 114 and the outer frame 111 respectively through the inner rubber body 118 and the outer rubber body 116, and completely separates the inner rubber body 118 and the outer rubber body 116. The middle frame 117 has a plate-like structure that is roughly parallel to the inclined side 1142. The outer frame 111 is provided with a support slope 1112 that is roughly parallel to the inclined side 1142 on both sides of the X direction. The end face of the upper limit inner rubber body 119 is provided with a positioning protrusion 1141 for fitting the buffer side pad 12. The lower limit inner rubber body 113 has a U-shaped structure covering the bottom surface of the inner frame 114. The conical inner frame 114 is vertically installed inside the outer frame 111, providing vertical stiffness for the suspension bushing 11. The buffer gaps at the top and bottom ends can be used to absorb vertical vibrations. The inclined side 1142 has a large contact surface for transmitting vibrations. The supporting rubber is inclined upward and fixed to the inclined side 1142 on both sides, distributing the vertical load to the X direction, resulting in better vibration reduction and durability.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
