Abstract
The utility model relates to a straight joint body. It includes the joint body that has connecting axle mounting hole, and the connecting axle that has the backup pad is adorned in connecting axle mounting hole, characterized by: the connecting shafts on two sides of the supporting plate are provided with wear-resistant sleeves, a buffer block is arranged between each wear-resistant sleeve and the inner surface of the joint body, a movable gap is arranged between each wear-resistant sleeve and the supporting plate, and two ends of a mounting hole of each connecting shaft are fixed with a positioning mechanism through sealing buffer rings. Because the wear-resistant sleeve is additionally arranged, the strength of the flexible body part is increased, but the flexibility is still kept between the buffer block and the joint body, so that the swinging property of the connecting shaft is ensured, and the original characteristics of the connecting shaft are kept. In addition, the sliding sleeve is supported in the installation between backup pad and the joint body, has further guaranteed the utility model discloses a flexibility and wearability.
Description
Technical Field
The utility model relates to a straight joint body.
Background
The thrust rod of commercial truck for Dongfeng, liberation, etc. in the prior art has two joint bodies in which a connecting shaft is installed. The flexible body is arranged between the connecting shaft of the existing straight joint body and the shell of the straight joint body, but although the flexible body can adjust the connecting shaft to a corresponding angle along with the swinging of a vehicle, the reaction force of an automobile on a thrust rod is relieved, the connecting shaft is not easy to damage, and the connecting shaft is protected, but the flexible body is easy to damage due to poor wear resistance, so that the service life of the straight joint body is influenced.
Disclosure of Invention
The utility model aims to provide a: the straight joint body is designed, so that the connecting shaft can be ensured to have a certain swinging space and certain wear resistance, and the service life of the straight joint body is prolonged.
The utility model discloses a joint body with connecting axle mounting hole, the connecting axle that has the backup pad is adorned in the connecting axle mounting hole, and its technical scheme is: the connecting shafts on two sides of the supporting plate are provided with wear-resistant sleeves, a buffer block is arranged between each wear-resistant sleeve and the inner surface of the joint body, a movable gap is arranged between each wear-resistant sleeve and the supporting plate, and two ends of a mounting hole of each connecting shaft are fixed with a positioning mechanism through sealing buffer rings.
Furthermore, a middle bearing sliding sleeve is arranged between the supporting plate and the joint body.
Preferably, the buffer block is fixedly connected with the wear-resistant sleeve on the same side.
Specifically, the outer end face of the buffer block is provided with a sealing buffer ring mounting groove, wherein a sealing buffer ring is respectively mounted.
Further, the sealing buffer ring is positioned on the outer sides of the wear-resistant pad and the buffer block.
Specifically, a joint body at one end of a connecting shaft mounting hole is provided with an inward boss, and a sealing buffer ring is matched with the boss; the other end of the connecting shaft is provided with a retaining ring at the outer end of the sealing buffer ring, the surface of the connecting shaft mounting hole is provided with a clamping groove, and a clamping spring matched with the retaining ring is arranged in the clamping groove.
Because the wear-resistant sleeve is additionally arranged, the strength of the flexible body part is increased, but the flexibility is still kept between the buffer block and the joint body, so that the swinging property of the connecting shaft is ensured, and the original characteristics of the connecting shaft are kept. In addition, the sliding sleeve is supported in the installation between backup pad and the joint body, has further guaranteed the utility model discloses a flexibility and wearability.
Drawings
Fig. 1 is a cross-sectional view of the present invention;
the connector comprises a connecting shaft 1, a connecting shaft 2, a connector body 3, a middle bearing sliding sleeve 4, a buffer block 5, a sealing buffer ring 6, a positioning retainer ring 7, a supporting plate 8, a wear-resistant sleeve 9 and a clamp spring.
Detailed Description
As shown in the figure, the present embodiment includes a joint body 2, a connecting shaft mounting hole with two open ends is arranged on the upper portion of the joint body 2, the mounting hole is a cylindrical hole, and the mounting hole may be a hole with other shapes according to actual requirements. The connecting shaft mounting hole has an inward boss at one end, and specifically, a projecting ring structure is generally adopted. This kind of structure can be realized with the structure of jump ring, but this kind of structure of this embodiment is more convenient for processing and the dismouting of this embodiment.
The connecting shaft 1 of the embodiment comprises a connecting part with connecting holes at two ends, a cylindrical part corresponding to the joint body 2 and a supporting plate 7 positioned in the middle of the cylindrical part, wherein the outer diameter of the supporting plate 7 is smaller than the inner diameter of the connecting shaft mounting hole, and a gap is formed between the supporting plate 7 and the inner wall of the connecting shaft mounting hole, and the gap can be empty, but a middle bearing sliding sleeve 5 with certain flexibility can also be installed.
The connecting shafts 1 on two sides of the supporting plate 7 are respectively provided with a wear-resistant sleeve 8, and a gap is reserved between the wear-resistant sleeve 8 and the supporting plate 7. The outer surfaces of the two wear-resistant sleeves 8 are fixedly connected with the buffer blocks 4 on the same side respectively, and the two wear-resistant sleeves can be connected in a bonding or other known modes. The outer wall of the buffer block 4 is matched with the inner wall of the connecting shaft mounting hole, and the inner end face of the buffer block 4 is matched with the support plate 7; when the middle bearing sliding sleeve 5 is installed, the inner wall of the middle bearing sliding sleeve is also matched with the middle bearing sliding sleeve 5. The buffer block 4 and the bearing sleeve 5 can be made of the same material.
The outer ends of the two buffer blocks 4 are respectively provided with a sealing buffer ring mounting groove, the thicker part of the sealing buffer ring 5 is arranged in the groove, and the other part of the sealing buffer ring is positioned at the outer side of the wear-resistant sleeve 8. The thicker part of the sealing buffer ring 5 at one end is matched with the convex ring of the connecting shaft mounting hole, the outer side of the thicker part of the sealing buffer ring 5 at the other end is provided with a positioning check ring 6, and the outer part of the positioning check ring 6 is matched with a clamp spring 9. The clamp spring 9 is clamped in a clamping groove on the inner surface of the connecting shaft mounting hole.
