What are the different types of urethan housing?

polyurethane polymer or urethane is part of a family of chemical compounds that show features similar to natural rubber; It is elastic and flexible. Urethane has advantages beyond the rubber because it has a high capacity carrying a load, a better set of compression and a significantly stronger tears. It is also tolerant of grease, oil and ozone and has greater abrasion resistance. The compound is completely synthetic and can be shaped into a very soft or hard material. Urethan cases are often used in automotive works and industrial facilities, mainly because of their Advtangs over the rubber and their ability to form into unique patterns. The main types of cases they use are the end beam case, the center of the pedestrian beam and the torque for torque. All cases in this type of vehicle use polyurethane polymer. The case itself consists of three layers: an outer bushing piece, an inner case and a polyurethane case located between the outer and inner housingIt is the life of the bushing and the truck hanging. Before using the urethhan case, trucks with a heavy rubber interface were used, which had a shorter life instead of a polyurethane case.

Another type of urethan housing is used on the joint connecting the binding rod with the lever arm as part of the vehicle control mechanism. This joint must be constructed in such a way that there is an angular deflection and no stiffness in the mechanism. If the driver often uses it, it must also be robust against excessive wear. The spherical joints were once used because they provided a mechanism with a good angular deflection, but were expensive to build and repair. Urethan cases are more economical, simply designed, have an extended life and do not wear as much as the joints.

trailer, such as steering mechanisms, also used swivel joints. These types of joints attached two vehicles, allowing them to turn under ÚHLem due to each other when performing left and right turn. The joint, however, has worn rapidly and any shocks from one vehicle would be transferred to the connected vehicle - for example, from a trailer to the driver's vehicle. Another mechanism that uses urethhane cases reduces the wear of the hinge mechanism and also distributes the shock effect in the extended time interval. This is also known as vibration reduction, which is a benefit to the driver.
