Everyone is no stranger to the thrust rod, and it is also a wearing part of the truck, especially the dump truck, which often breaks the rod and loosens the rubber core. In fact, the role of the thrust rod in a car is very important, it has no load-bearing role. The leaf spring in the balanced suspension of the two Bridges distributes the load to the middle and rear axle, which can only transfer the vertical force and lateral tension, but not the traction force and braking force, so it is also divided into the upper and lower thrust rods, which are used to transfer the longitudinal load and torque. Achieve vehicle load balance function.

In the case of uneven load on the road, the rubber core of the thrust rod will not only rotate but also twist, the general dump truck is more prominent, because the working condition is not too good, due to the large market demand, the market has also appeared a lot of shoddy products. There are rubber cores, and there are assemblies.

Take a look at what products are available on the market:

The first is the so-called rubber core of tendon material.

This kind of rubber core has almost no elasticity, it will be very tight, once a little loose, it will crack, because it is processed with a strong hardness of raw rubber. In the process of force transmission, the rubber core will move with the imbalance of torque, which has almost no buffer effect, and will lead to broken rods and steel plate cracking.

Second kind of black raw glue core

This kind of rubber core can be elastic, but a twist will appear internal cracking, the material is too brittle. For a long time, there will be a large gap loosening, and the internal ball will touch the aperture wall, and the consequences will be hard.

Here's a look at what the most scientifically designed thrust rod rubber core looks like:

Rotational torque balance, multi-groove fixed, and the use of raw rubber processing, the inner wall using thickened materials, this is a qualified torque core.

In simple terms, raw rubber is unvulcanized rubber with various additives and fillers, and it can be dissolved in organic solvents. The cooked rubber, as the name suggests, of course, is processed on the basis of raw rubber, generally in the rubber industry, vulcanized rubber is cooked rubber, its raw material is the rubber after mixing the rubber under a certain temperature, pressure and time, by crosslinking from linear macromolecules into three-dimensional network structure and obtained rubber. Here alone, the so-called mixed rubber is actually a rubber that is evenly mixed with raw rubber and the compounding agent after processing and is not cross-linked. Vulcanized rubber is generally insoluble in solvents. In general, the biggest difference between raw rubber and cooked rubber, from the actual performance to distinguish, is that raw rubber is smaller than cooked rubber in terms of tensile strength or resilience, and raw rubber surface is rough, cooked rubber is generally smooth.
