Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a new energy thrust rod. Background Technology

[0002] With the development of economy and science and technology, automobiles have become the most important means of transportation for people. Auto parts are the various units that make up a car and the products that serve the car. There are many types of auto parts. As people's living standards improve, people's consumption of automobiles is also increasing, and the market for auto parts is becoming larger and larger. In recent years, auto parts manufacturers have also been developing rapidly.

[0003] A thrust rod is an auxiliary component in a suspension system that improves vehicle balance, preventing lateral rollover caused by excessive body roll during cornering and thus avoiding accidents. The thrust rod has bushings at both ends, with connecting parts at the bushings, and an elastic rubber core covering the connecting parts. The thrust rod connects to the left and right suspensions via these connecting parts. In the event of lateral roll, the swinging of the connecting parts cushions the pressure generated by the roll. New energy vehicles require lightweight design. Because the battery packs in new energy vehicles are heavy and unsprung mass affects range, lightweighting must be a priority. Therefore, a lightweight thrust rod needs to be designed for use in new energy vehicles, ensuring that the thrust rod meets operational requirements without affecting range. Utility Model Content

[0004] Therefore, in order to address the above problems, this utility model proposes a new energy thrust rod that is structurally stable and durable, reduces unsprung mass, and increases driving range.

[0005] To solve this technical problem, the present invention adopts the following solution: a new energy thrust rod, comprising a rod body, a first rubber core seat, a second rubber core seat, a first torque rubber core, and a second torque rubber core. The rod body is a 6082-T6 aluminum alloy rod body. The first and second rubber core seats are both 6082-T6 aluminum alloy rubber core seats. The first and second rubber core seats are respectively welded to both ends of the rod body. The first torque rubber core includes a first metal sleeve connecting to the axle and a first rubber body vulcanized and bonded to the first metal sleeve. The second torque rubber core includes a second metal sleeve connecting to the subframe end and a second rubber body vulcanized and bonded to the second metal sleeve. The first torque rubber core is pressed into the first rubber core seat through an interference fit with the first rubber body. The first rubber core seat has first end caps at both ends that limit the movement of the first torque rubber core. The second torque rubber core is pressed into the second rubber core seat through an interference fit with the second rubber body. The second rubber core seat has second end caps at both ends that limit the movement of the second torque rubber core.

[0006] In a further improvement, the rod is a hollow tube with a circular or rectangular cross-section.

[0007] In a further improvement, the first rubber body and the second rubber body are natural rubber or a mixture of natural rubber and styrene-butadiene rubber.

[0008] Further improvements include a first reinforcing sleeve and a second reinforcing sleeve, which are respectively fitted onto the welding joint between the first rubber core seat and the rod body and the welding joint between the second rubber core seat and the rod body.

[0009] In a further improvement, both the first reinforcing sleeve and the second reinforcing sleeve include clamps and positioning bolts for locking the clamps. The clamps cover the welding point between the first rubber core seat and the rod body or the welding point between the second rubber core seat and the rod body and are locked by the positioning bolts.

[0010] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows: By using 6082-T6 aluminum alloy rod body and 6082-T6 aluminum alloy rubber core seat to weld together to form the thrust rod body, the resulting thrust rod has high overall strength and good corrosion resistance. Furthermore, the rod body and rubber core seat can be welded together, making the overall connection structure stable and durable, significantly reducing unsprung mass and improving the driving range of new energy vehicles. The outer diameter of the torque rubber core is set to be slightly larger than the inner diameter of the rubber core seat, and an interference fit is used for pressing and assembly. This utilizes the elastic deformation of the rubber body for pressing, and relies on the frictional force generated between the torque rubber core and the rubber core seat through the interference fit to transmit the torque and part of the axial force between the axle and the subframe end. The contact surfaces of the rubber body and the rubber core seat are lubricated with a lubricant (such as a water-based lubricant) during pressing, which facilitates the pressing process and avoids the formation of easily worn hard friction between the surface of the rubber body and the inner wall of the rubber core seat. The end caps increase the safety of the torque rubber core, preventing it from detaching from the rubber core seat and thus preventing excessive suspension displacement that could lead to accidents. The interference fit between the rubber body and the rubber core seat allows the rubber body to be subjected to a certain radial pre-compression, which significantly improves its load-bearing capacity, stiffness, and fatigue life, making it more suitable for the load and space requirements of new energy vehicles. The first and second reinforcing sleeves further enhance the strength of the connection structure between the rod and the rubber core seat, making the overall structure more stable and allowing for widespread application.
