Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive rear suspension technology, and in particular to a thrust rod connection structure for a rear suspension. Background Technology
[0002] The thrust rod in a car, also known as a thrust arm or push rod, is an important component of the suspension system. It is typically used to control the vertical movement of the wheels and limit their longitudinal (forward and backward) displacement. The thrust rod plays a crucial role between the vehicle body and the wheels, helping to ensure the vehicle's handling, stability, and comfort.
[0003] Existing V-type thrust rod designs typically employ a cross pin connection method, where the cross pin passes horizontally through the thrust rod, thus fixing the thrust rod to the rear suspension system. Because the cross pin has a strong transmission capacity in the horizontal direction, it can effectively achieve smooth horizontal movement of the thrust rod.
[0004] However, using only a cross pin connection has certain limitations. Although the cross pin can effectively transmit horizontal forces, its constraint ability in the vertical direction is weak. Especially when the thrust rod is subjected to the vertical vibration of the vehicle or the impact of uneven road surfaces, the cross pin connection structure is prone to causing the thrust rod to wobble. This wobble will affect the stability and comfort of the suspension system. In particular, during large longitudinal acceleration or braking, the vibration of the thrust rod will be aggravated, which may lead to inaccurate wheel alignment or reduced handling performance. Utility Model Content
[0005] The purpose of this invention is to address the limitations of existing technologies that rely solely on horizontal pin connections. While horizontal pins can effectively transmit horizontal forces, their constraint capacity in the vertical direction is relatively weak.

[0029] All eight bolts are matched with the threaded grooves.
[0030] The technical effect of adopting the above-mentioned further solution is that it allows the bolts to be embedded inside the threaded groove to fix the cover plate.
[0031] In a preferred embodiment, the lubrication assembly includes:
[0032] The fuel tank is fixedly installed on the top left side of the connecting bracket;

[0046] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0047] 1. In use, the cover plate and bolt structure of this utility model not only further fixes the thrust rod body, ensuring it remains in the correct position during operation and preventing displacement caused by vibration or external impact, but also strengthens the connection between the cover plate and the connecting column with bolts, making the connection more robust. This combination effectively reduces the vertical movement space of the thrust rod body, further reducing vertical swaying. It solves the limitations of the existing technology that only uses a horizontal pin connection, which, although the horizontal pin can effectively transmit horizontal force, has weak constraint ability in the vertical direction.
[0048] 2. In use, the nozzle and sponge pad structure of this utility model allow the sponge pad to continuously absorb lubricating oil. The sponge pad is also in contact with the connection between the pin and the thrust rod body, which means that the lubricating oil will not be consumed or dissipated quickly. At the same time, the sponge pad can provide continuous lubrication, ensuring that the friction between the pin and the thrust rod body is effectively lubricated, thus extending the service life of the parts.

[0056] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0057] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0058] Example 1, such as Figures 1-5 As shown, this utility model provides a thrust rod connection structure for a rear suspension, including a thrust rod body 1, a connection assembly, and a lubrication assembly;
[0059] The connecting components include: a connecting bracket 101 is provided at the bottom left side of the thrust rod body 1, and connecting columns 102 are fixedly installed on both sides of the top of the connecting bracket 101. In this design, the pin 103 is embedded in the inside of the connecting column 102, which can provide stronger support for the thrust rod. The connecting column 102 plays a role in stabilizing the connection between the thrust rod and other components, thereby enhancing the stability of the overall structure. The pin 103 is movably embedded in the left side of the inside of the thrust rod body 1, and the pin 103 is movably embedded in the inside of the two connecting columns 102.
[0060] In addition, multiple reinforcing plates 104 are fixedly installed on the outer surfaces of the two connecting columns 102. The bottom of the multiple reinforcing plates 104 is fixedly installed on the top of the connecting bracket 101 so as to effectively improve the rigidity of the connecting column 102 through the reinforcing plates 104, making the connecting column 102 less prone to deformation when subjected to external load, thereby improving the strength of the entire thrust rod body 1.
[0061] Both sides of the pin 103 have connecting grooves 105. The two connecting posts 102 are slidably connected with pins 106. In this design, the cooperation between the pins 106 and the connecting grooves 105 can ensure that the pin 103 can be firmly fixed in the connecting posts 102 during operation. Both pins 106 are matched with the connecting grooves 105. The right side of both pins 106 is fixedly installed with a return spring 107. The design of the return spring 107 allows the pins 106 to automatically return to their original position after being removed from the external force. The other end of both return springs 107 is fixedly installed on the left side of the connecting post 102.
[0062] Both connecting posts 102 are movably connected to the top of a cover plate 108. Both cover plates 108 are movably fitted onto the top outer surface of the pin 103. Both cover plates 108 are threaded around their inner perimeter with bolts 109. In this design, the threaded connection not only ensures that the cover plate 108 is firmly connected to the connecting post 102, but also prevents the cover plate 108 from being misaligned or shifted due to vibration or external force during use. Both connecting posts 102 are provided with threaded grooves 110 around their inner perimeter, and all eight bolts 109 are matched with the threaded grooves 110.
[0063] In this embodiment, the operator can first pull the pin 106 to the left, allowing it to slide to the left inside the connecting post 102, while simultaneously pulling the return spring 107 to extend. Then, the operator presses down on the push rod body 1, allowing the pin 103 to embed into the two connecting posts 102, and releases the pin 106, causing the return spring 107 to reset. While resetting, the operator can pull the pin 106 to the right to embed it into the connecting groove 105, thereby fixing the push rod body 1 and the connecting bracket 101 and preventing horizontal movement of the push rod body 1 during use.
[0064] Example 2, as Figures 1-5 As shown, the lubrication assembly includes: an oil tank 2 is fixedly installed on the top left side of the connecting bracket 101, and a pump 202 is fixedly connected to the top of the oil tank 2. In this design, the flow of oil can be achieved through the power transmission of the pump 202, which can ensure that the oil pump can effectively pump and deliver the oil in the oil tank 2. An oil filling pipe 201 is fixedly embedded on the top front side of the oil tank 2, and the oil filling pipe 201 facilitates the oil filling operation of the oil tank 2.
[0065] The right side of the pump 202 is connected to an oil pipeline 203. In this design, the oil pipeline 203 can effectively deliver oil to the nozzle 205. Two nozzles 205 are fixedly installed at the other end of the oil pipeline 203. A sponge pad 206 is fixedly connected to the opposite side of the two nozzles 205. The two sponge pads 206 are movably connected to the connection of the pin 103 with the thrust rod body 1.
[0066] In addition, support plates 204 are fixedly fitted on both sides of the oil pipeline 203. In this design, the support plates 204 are on both sides of the oil pipeline 203, which can provide additional support and increase the stability of the pipeline. The bottom of the two support plates 204 are fixedly installed on the top of the connecting bracket 101.
[0067] In this embodiment, personnel can start the pump 202 through the power supply system of the pump 202, so that when it is running, it can draw out the lubricating oil inside the oil tank 2 and deliver the lubricating oil to the nozzle 205 through the oil delivery pipe 203.
[0068] Working principle: In use, after the thrust rod body 1 is fixed to the connecting bracket 101 by the pin 106, the operator can press down the cover plate 108 so that its bottom can fit against the top of the connecting column 102, and the cover plate 108 can be sleeved on the top outer surface of the pin 103. Then the operator can rotate the bolt 109 so that it can be embedded in the threaded groove 110 inside the connecting column 102 to fix the cover plate 108 to the connecting column 102 and provide additional reinforcement to the thrust rod body 1. The structure of the cover plate 108 and the bolt 109 not only further fixes the thrust rod body 1, keeping it in the correct position during operation and avoiding displacement caused by vibration or external impact, but also strengthens the connection between the cover plate 108 and the connecting column 102 by the bolt 109, making the connection more secure. This combination can effectively reduce the vertical movement space of the thrust rod body 1 and further reduce vertical swaying.
[0069] During use, when lubricating oil enters the nozzle 205, it can be injected into the sponge pad 206 through the nozzle 205. The sponge pad 206 is movably attached to the connection between the pin 103 and the thrust rod body 1. This allows the thrust rod body 1 to be lubricated by the sponge pad 206 when it rotates on the outer surface of the pin 103. Due to the structure of the nozzle 205 and the sponge pad 206, the sponge pad 206 can continuously absorb lubricating oil. The movable attachment of the sponge pad 206 to the connection between the pin 103 and the thrust rod body 1 means that the lubricating oil will not be quickly consumed or dissipated. At the same time, the sponge pad 206 can provide continuous lubrication, ensuring that the friction between the pin 103 and the thrust rod body 1 is effectively lubricated, thus extending the service life of the components.
[0070] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
