Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a shock-absorbing bushing for a pickup truck chassis. Background Art

[0002] The automobile chassis supports and installs the automobile engine and its various components and assemblies to form the overall shape of the automobile, and the bushing is one of the important components of the automobile chassis. It plays the role of connecting various parts of the car body and transmitting the chassis to the car body to reduce shock.

[0003] As disclosed in publication number: CN109094315A, a combined rubber bushing for an automobile chassis is disclosed, comprising a sleeve body, an outer sleeve body is fixedly connected to the top and bottom of the sleeve body, an outer buffer rubber plate is fixedly connected to the outer side of the sleeve body, a buffer rubber is fixedly connected to the inner side of the outer buffer rubber plate, an inner wall of the outer sleeve body is fixedly connected to a rubber seat, an open-hole shock-absorbing rubber is fixedly connected to the inside of the rubber seat, an elliptical hole is provided inside the open-hole shock-absorbing rubber, a closing oblique structure is provided at the top and bottom ends of the outer sleeve body, an upper adhesive plate and a lower adhesive plate are fixedly connected to the middle position of the inner part of the sleeve body, and the inner sides of the upper adhesive plate and the lower adhesive plate are respectively fixedly connected to the buffer bushing splits.

[0004] The above device achieves the purpose of reducing the vibration of the automobile chassis and reducing noise by combining rubber bushings, but there are still certain defects in actual use. The rubber sleeves at the connection points at both ends of the bushing are in a working state for a long time, and their own wear is more serious than other internal rubbers, which makes the connection points at both ends more prone to damage or requires frequent replacement of the rubber at both ends. At the same time, the outer shell only relies on various combined rubber sleeves, and the shock absorption effect that can be achieved is relatively limited, and it is easy to accelerate the wear of the rubber sleeves, thereby increasing the maintenance cost. Utility Model Content

[0005] The purpose of the utility model is to provide a shock-absorbing bushing for a pickup truck chassis, so as to solve the problems mentioned in the above background technology that the rubber connecting the automobile parts wears out quickly and needs to be replaced frequently, which affects the use, and the shock-absorbing effect is single and cannot effectively provide supporting force, which is only dependent on rubber for shock absorption.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: a shock-absorbing bushing for a pickup truck chassis, comprising a bushing outer ring, a bushing inner ring, a connecting sleeve, an automobile component and a sliding block, wherein the bushing inner ring is arranged inside the bushing outer ring, and a connecting sleeve is fixedly installed on the upper end of the bushing inner ring, and the bushing outer ring and the bushing inner ring are nested and installed in the automobile component, and further comprising:

[0007] A movable block is fixedly mounted on the inner wall of the outer ring of the bushing, a connecting rod is rotatably mounted on the movable block, and an extrusion block is rotatably mounted on the connecting rod;

[0008] A fixed block, which is fixedly mounted on the outer wall of the inner ring of the bushing, and the fixed block is provided with a track groove, and the track groove is provided with two groups symmetrically in the upper and lower directions about the horizontal center line of the fixed block;

[0009] A connecting block is fixedly mounted on the inner wall of the outer ring of the bushing, and a supporting block is connected and mounted on the connecting block.

[0010] Furthermore, the connecting sleeve is symmetrical up and down about the horizontal center line of the outer ring of the bushing, and a rubber outer sleeve is fitted on the inner wall of the connecting sleeve, and a plurality of groups of support springs are arranged on the rubber outer sleeve at equal angles with the connecting sleeve as the center of the circle, and a rubber inner sleeve is connected and installed on the other end of the support spring. When the inner and outer rubber sleeves are worn, the elastic force of the support spring will squeeze the rubber inner sleeve and the rubber outer sleeve toward both sides respectively so that they still fit with the parts to prevent gaps due to wear. At the same time, the support springs arranged at equal angles can have a certain shock-absorbing effect on the connection.

[0011] Furthermore, the connecting rod is symmetrically installed in two groups about the horizontal center line of the movable block, and a torsion spring is connected and installed on the connecting rod, and the other end of the torsion spring is connected to the movable block. At the same time, the connecting rod and the movable block form an elastic structure through the torsion spring. When the outer ring of the bushing is impacted by external force, the force generated by the deformation drives the connecting rod to deflect through the movable block.

[0012] Furthermore, a movable groove is provided on the connecting block, and a tension spring is installed in the internal connection of the connecting block, and a sliding block is movably installed in the movable groove. At the same time, the sliding block forms an elastic structure on the movable groove through the tension spring, and the sliding block will move left and right in the movable groove through the tension spring.

[0013] Furthermore, the sliding block is symmetrically installed on the support block up and down, and the support block forms a sliding structure on the connecting block through the sliding block, and the lower end of the support block is in contact with the extrusion block. At the same time, the connecting block is symmetrical up and down about the horizontal center line of the outer ring of the bushing, and the support block moves left and right on the connecting block through the sliding block, thereby providing a supporting force opposite to the impact force.

[0014] Furthermore, the extrusion block is trapezoidal in front view, and is slidably installed in the track groove. The extrusion block and the movable block form a connecting rod structure through a connecting rod, and the extrusion block moves in the track groove under the push of the connecting rod.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The shock-absorbing bushing for the chassis of the pickup truck is used in coordination with the connecting sleeve, the rubber outer sleeve, the supporting spring and the rubber inner sleeve. After the connecting sleeve is connected to the automobile part, the rubber outer sleeve and the rubber inner sleeve will be worn during long-term use. However, the supporting spring connected between the rubber outer sleeve and the rubber inner sleeve still presses the rubber outer sleeve and the rubber inner sleeve tightly on the surface of the object through elastic force, so that there will be no gap due to wear and tear, which will affect the subsequent use. At the same time, the supporting spring arranged inside will also reduce the shock of the connection;

[0017] 2. The shock-absorbing bushing for the pickup truck chassis is used in coordination with the movable block, the fixed block, the connecting block, the connecting rod, the extrusion block and the supporting block. When the outer ring of the bushing is deformed due to external force, the movable block will push the connecting rods on both sides to deviate, so that the extrusion block pushes the supporting block to move in the opposite direction of the force. When impacted, the supporting block provides a supporting force opposite to the external force, thereby enhancing the overall shock-absorbing strength between the outer ring and the inner ring of the bushing and improving the service life of the parts.
