Description
A TORQUE ROD WITH REDUCED WEIGHT AND IMPROVED THERMAL CONDUCTIVITY
TECHNICAL FIELD
The invention relates to a torque rod that is positioned between the axle and the body of a vehicle and serves to reduce the transmission of vibrations between the axle and the body.
BACKGROUND
Heavy commercial vehicles have a torque rod to provide the connection between the axle and the chassis. As a result of the movement of the vehicle, uncontrolled movements on the wheels are carried to the axle body depending on the form of the ground on the road. While some of these uncontrolled movements and vibrations are damped on the wheels, most of them are transmitted to the axle.
The suspension system, which is rigidly connected between the axle and the vehicle body, converts these unwanted uncontrolled movements into low amplitude, controlled, and limited oscillating movements in the vehicle body. Thus, the torque rod provides comfort for the passenger in the vehicle. However, the inertia in the mass of the vehicle and the negative effects of the traction force on the wheels, and the lateral forces that occur during the cornering of the vehicle are transmitted to the vehicle body through the suspension system and the torque rod. There are also V-shaped versions of the torque rods, which are connected to a single joint.
The existing torque rods are made of forged steel material. Forged steel torque rods have negative features such as high weight and high heat transmission coefficient. The high weight causes the CO2 emissions to increase in vehicles with internal combustion engines and the range to decrease in electric vehicles with fuel consumption. The high heat transmission coefficient leads to the heating of the torque rod under repeated load.
Application US2005006869, which is in the literature, relates to a composite suspension rear rod for heavy-duty vehicles. Accordingly, the back rod is made of a composite material comprising a matrix material and a reinforcing material. According to the explained embodiment, the back rod may comprise an epoxy resin matrix, the materials of which are reinforced with carbon fiber.
As a result, all the above-mentioned problems have made it imperative to innovate in the relevant technical field.
BRIEF DESCRIPTION OF THE INVENTION
The present invention relates to a torque rod for eliminating the above-mentioned disadvantages and bringing new advantages to the relevant technical field.
The existing torque rods in the technical field of the invention have a high weight due to the mechanical properties of the material they contain. However, the currently known torque rods can heat up quickly under repeated load due to the heat conduction coefficients they have.
Accordingly, an object of the invention is to introduce a weight-reduced torque rod.
Another object of the invention is to provide an improved heat conduction coefficient torque rod.
Another object of the invention is to provide a torque rod with a self-healing property.
The present invention is a torque rod that is positioned between the axle and the body of a vehicle and serves to reduce the transmission of vibrations between the axle and the body in order to realize all the objects that will emerge from the abovementioned and the following detailed description. Accordingly, the novelty of the invention is that it is composed of composite material and comprises the following:
Polyamide-6 as a matrix component,
At least one reinforcing component selected from the group of carbon fiber and glass fiber materials in continuous form,
At least one additive material in the nanoscale for increasing its thermal conductivity.
A possible embodiment of the invention is characterized in that said reinforcement component is fiber.
Another possible embodiment of the invention is characterized in that the reinforcing component is glass fiber.
Another possible embodiment of the invention is characterized in that the matrix component comprises caprolactam-modified polyamide-6.
Another possible embodiment of the invention is characterized in that the matrix component comprises PA-6 in a ratio selected in the range of 35-45 wt%.
Another possible embodiment of the invention is characterized in that it comprises a ratio of reinforcement components selected in the range of 55-65 wt%.
Another possible embodiment of the invention is characterized in that it comprises nanoparticle additives comprising boron nitride, carbon nanotube, graphene, alumina, graphite, and aluminum.

DETAILED DESCRIPTION OF THE INVENTION
In this detailed description, the subject matter of the invention is explained only by means of examples that will not have any limiting effect for a better understanding of the subject matter.
Figure 1 shows a representative perspective view of the torque rod (10) of the invention. The torque rod (10) of the invention is positioned between the axle and the vehicle body, especially in heavy vehicles. The torque rod (10) provides partial damping of uncontrolled movements such as vibration transmitted from the axle to the vehicle body. The torque rod (10) may be in the form of V, which is one of the known embodiments in the art. Accordingly, the composite material embodiment disclosed in the invention is independent of the form of the torque rod (10).
The torque rod (10) is composed of a composite material. By "composite material" in the invention is meant a group of materials that are preferred in many areas due to their advantages such as durability, lightness, and cost-effectiveness and contain matrix component and reinforcing component(s).
The torque rod (10) of the invention is preferably a continuous fiber-reinforced thermoplastic composite material. Accordingly, the torque rod (10) comprises polyamide-6 (PA-6) as the thermoplastic matrix material in a ratio selected in the range of 35%-45%. However, as a reinforcing material, it comprises at least one reinforcing component in a ratio selected in the range of 55%-65%.
The composite material of the invention comprises at least one of the groups of carbon fiber and glass fiber materials in continuous form as a reinforcing component.
The composite material of the invention preferably comprises glass fibers as a reinforcing component. The glass fiber is preferably in continuous form (filament).
The torque rod (10) of the invention essentially comprises caprolactam-modified polyamide. The caprolactam modification gives the torque rod (10) a self-healing feature.
The torque rod (10) comprises at least glass fibers as a reinforcing component within the body, as well as preferably at least one nanoscale additive material to improve thermal conductivity. Boron nitride 600 W/mK, carbon nanotube 3000 W/mK, graphene 5000 W/mK, alumina 25 W/mK, graphite (thermal conductivity value 5300 W/mK) and aluminum 200 W/mK can be selected as the mentioned nanoscale additive material. By improving the thermal conduction coefficient, the torque rod (10) is prevented from heating rapidly under repeated load. The mentioned nano-additives are preferred because they have high thermal conductivity. The volumetric ratio of nanomaterials is a maximum of 10%. The thermal conductivity of the polymer matrix materials can be increased up to 2 to 10 times according to the nanoparticle additive type and ratio. Accordingly, approximately. A thermal conductivity value in the range of 0.5 W/mK to 2.5 W/mK can be obtained.
The inventors have presented studies for obtaining the matrix component contained in the composite material from the polymerization of a mixture comprising at least one activator, at least one catalyst, and at least one precursor. The matrix employed at least 1 ,6- hexamethylene diisocyanate compound as the activator for the production of the component. In the invention, sodium-containing catalyst(s) are used as catalysts for obtaining the matrix component. Polyamide compound was used as the main raw material for obtaining the matrix component.
With all these described embodiments, the torque rod (10) of the invention is at least 65% lighter than the forged steel torque rod (10) known in the present art. With this weight gain,
the torque rod (10) reduces fuel consumption and improves emission values for the vehicle on which it is positioned.
The torque rod (10) has an increased fatigue life of 30% compared to the continuous fiber- reinforced thermoplastic composite material with and without nano-additives and microcapsules. In this way, the torque rod (10) subject to the invention can be used for a longer time, which reduces the maintenance and repair costs.
The described material structures and the torque rod (10) are made of 100% recyclable material. Thus, when the torque rod (10) has completed its life, it can be recycled and the damage to the environment is minimized.
The protection scope of the invention is specified in the appended claims and cannot be strictly limited to those explained in this detailed description for illustrative purposes. It is evident that a person skilled in the art may exhibit similar embodiments in light of the foregoing without departing from the main theme of the invention.
