The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1 to 4, the present invention provides a spare tire installation assembly, which generally includes a driving mechanism assembly 1, a fixing bracket 2, a spare tire upper fixing frame 3, a spare tire lower bracket 4 and a cable 5. The driving mechanism assembly 1 is fixedly mounted on the bottom of the vehicle through a bracket or directly. One end of a steel wire rope 5 is coiled in the driving mechanism assembly 1, and the other end of the steel wire rope penetrates through the fixed support 2 and the spare tire upper fixing frame 3 and then is connected with the spare tire lower bracket 4. The fixed bracket 2 and/or the spare tire upper fixing frame 3 are fixedly arranged at the bottom of the vehicle. The spare tire upper fixing frame 3 is fixedly connected with the fixing support 2. The spare tire body (not shown in the figure) is arranged between the spare tire lower bracket 4 and the spare tire upper fixing frame 3. After the spare tire body installation, the downside of spare tire body holds in the palm 4 upsides of spare tire bottom bracket, and the upside of spare tire body supports to lean on the contact with the downside of spare tire upper mounting bracket 3 to make spare tire bottom bracket 4 and spare tire upper mounting bracket 3 press from both sides the spare tire body tight fixed, with spacing fixed carrying on of spare tire body, prevent in the marching or the abnormal sound that rocks the production of spare tire body when jolting the road surface.
Specifically, as shown in fig. 2, the spare tire lower bracket 4 includes a lower bracket body 41, a first wire rope sheath 42, an elastic member 43, and a connecting rod 44. The lower bracket body 41 is provided with a through hole at a central position thereof. The first wire rope sheath 42 is of a T-shaped structure with a through hole therein. First wire rope sheath 42 is installed in the perforation through interference fit for be zero clearance fit between first wire rope sheath 42 and lower bracket body 41, can make first wire rope sheath 42 install more firm, prevent to rock, it is more pleasing to the eye reliable. One end of the wire rope 5 passes through the through hole of the first wire rope sheath 42 and is fixedly connected with the connecting rod 44. The connecting rod 44 is a T-shaped structure, or the connecting rod 44 is a steel wire rope rivet joint. The connecting rod 44 is used to fix the wire rope 5 and prevent the wire rope 5 from falling off. The elastic member 43 is fitted over the connecting rod 44. One end of the elastic member 43 abuts against the connecting rod 44, and the other end, i.e., the top of the elastic member 43, abuts against the bottom of the first wire rope sheath 42. Alternatively, the elastic member 43 is a compression spring. The elastic piece 43 can be arranged to tighten the spare tire body after installation, so that the whole mechanism keeps a specific pretightening force, and abnormal sound is prevented from being produced on a bumpy road surface. The elastic member 43 and the first wire rope sheath 42 can reduce the impact on the connecting rod 44 during the movement of the spare tire body. The first wire rope sheath 42 can also prevent the friction cutting of the wire rope 5 by the sharp edge of the perforation of the lower bracket body 41, and separate the elastic member 43 from the lower bracket body 41, thereby avoiding the abnormal sound generated by the collision of the elastic member 43 and the lower bracket body 41.
Further, as shown in fig. 2 and 4, the contact portion of the lower bracket body 41 and the spare tire body is a tapered structure. The spare tire upper fixing frame 3 is provided with a step-shaped fixing step 31 matched with the spare tire body. The fixed step 31 is used for limiting and fixing the spare tire body. The fixed step 31 may be a one-stage, two-stage, or multi-stage structure. When the driving mechanism assembly 1 tightens up the steel wire rope 5, the spare tire body can be better fixed through the lower bracket body 41 with the conical structure and the spare tire upper fixing frame 3 provided with the stepped fixing step 31 matched with the spare tire body, and abnormal sound generated by shaking of the spare tire body is prevented. Optionally, annular stripes are arranged on each stage of the fixing steps 31 to increase the friction force with the spare tire body, and further prevent the spare tire body from shaking. Rubber or plastics are selected for the material of fixed step 31, can prevent the fish tail spare tyre body to reduce the abnormal sound.
In an alternative embodiment, the spare tire upper fixing frame 3 is provided with a fastener mounting hole 32. The spare tire upper fixing frame 3 is mounted on the bottom of the vehicle by fasteners.
In an optional embodiment, the device further comprises a guide rod 6, and the steel wire rope 5 is arranged inside the guide rod 6 in a penetrating mode. One end of the guide rod 6 is fixedly connected with the driving mechanism assembly 1. The fixed bracket 2 is provided with a through hole. The other end of the guide rod 6 is bent and penetrates through the through hole of the fixed support 2 to be fixedly connected with the fixed support 2. The bent end part of the guide rod 6 is arranged at the center of the spare tire upper fixing frame 3. A second bell-mouth-shaped steel wire rope sheath 61 is arranged at the port of the guide rod 6. The flared design may reduce friction between the wire rope 5 and the end of the guide rod 6. The first and second wire rope sheaths 42 and 61 are made of a rubber material or plastic. The second steel wire rope sheath 61 can reduce abnormal sound generated when the steel wire rope 5 collides with the port of the guide rod 6, and can avoid cutting caused by long-term friction of the port of the guide rod 6 on the steel wire rope 5.
When using, install the spare tyre body between spare tyre upper fixing frame and spare tyre lower carriage, then tighten up wire rope through the actuating mechanism subassembly, make the spare tyre body remove to spare tyre upper fixing frame department, and support the contact with the fixed step 31 of spare tyre upper fixing frame downside, this moment because the deformation of elastic component has certain pretightning force, tightly press from both sides the spare tyre body between spare tyre upper fixing frame and spare tyre lower carriage, prevent that the spare tyre body from rocking or colliding with other spare parts, thereby the production of abnormal sound has been avoided.
The invention provides a spare tire installation assembly which comprises a driving mechanism component, a fixing support, a spare tire upper fixing frame, a spare tire lower bracket and a steel wire rope, wherein a spare tire body is fixed and limited through the spare tire upper fixing frame and the spare tire lower bracket, so that abnormal sound caused by shaking of the spare tire body is prevented; the lower bracket body is isolated from the elastic piece through the first steel wire rope sheath which is arranged on the lower bracket body in an interference fit manner, so that abnormal sound caused by metal collision is prevented; the arrangement of the first steel wire rope sheath and the second steel wire rope sheath can also prevent impact friction to the steel wire rope at a through hole of the lower bracket body or a fracture of the guide rod, so that the steel wire rope is prevented from being cut, and the service life and the safety performance of the spare tire installation assembly are prolonged.
The spare tire installation assembly provided by the invention has the advantages of long service life, labor saving in operation, smooth and stable transmission and the like, and the whole mechanism keeps a specific pretightening force during use, so that abnormal sound on a bumpy road surface is prevented.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
