Description

Power Transmission Fluid with Extended Durability {POWER TRANSMISSION FLUIDS HAVING EXTENDED DURABILITY}

FIELD OF THE INVENTION

The present invention relates to a power transmission fluid with improved and / or extended durability. The present invention may include fluids suitable for power transmission fluids such as automatic transmission fluid (ATF) and / or manual transmission fluid. The power transmission fluid of the present invention may include a friction modifier, a borated dispersant, and a phosphorus containing antiwear component.

Prior art

Automotive power transmission fluids are required to provide special frictional properties under very excessive temperature and pressure conditions. When fluid friction changes due to the action of relative sliding speed, temperature, or pressure as a result of the above conditions, a performance degradation that can be immediately recognized by the vehicle driver is caused. Such effects include unacceptable long term or short term gear shifts, vehicle shudders or vibrations, noise and / or coarse shifts (“gear change shock”). Thus, there is a need for transmission fluids that produce minimal frictional changes under high temperature and high pressure conditions. The fluid will minimize device and performance issues while maximizing fluid change intervals. The fluid allows for smooth engagement of the torque converter and the shifting clutch, thereby minimizing vibration, vibration and / or noise, and in some cases, longer fuel life to improve fuel economy.

Disadvantages of conventional transmission fluids, including nitrogen-containing dispersants reacted with high amounts of phosphorylated and / or borated species (e.g., phosphorus and boron based acids, and their esters), are disadvantageous to the environment under which they are subjected to thermal stress. For example, it can be regressed in modern automatic transmissions. The degradation may be in the form of unfavorable frictional performance, such as an increase in the ratio of static to kinetic coefficient of friction or may be undesirable physical phenomena such as precipitation of decomposition products or glazing of clutch friction materials.

Friction modifiers are used in the automatic transmission fluid to reduce friction between surfaces (components of the torque converter clutch or shifting clutch) at low sliding speeds. As a result, the friction versus velocity (μ-v) curve has a positive slope, which results in a smooth clutch engagement and results in a "stick-slip" aspect (eg, shaking, vibration and coarse shift). Minimize). However, many conventional organic friction modifiers are thermally unstable. If the exposure to heat is prolonged, the additives decompose and lose the benefits they provide for clutch performance.

Disclosure of the Invention

Power transmission fluids formulated in accordance with the present invention provide improved frictional durability and provide improved performance for smooth engagement of the torque converter and shifting clutch, minimized vibration, vibration and / or noise, and / or improved fuel economy. In addition, embodiments disclosed herein may contain dispersants containing phosphorus and / or containing small amounts of boron, thereby improving thermal stability and improving frictional performance.

In one embodiment, the power transmission fluid may contain a base oil and an additive composition. The additive composition may comprise a borate dispersant, succinimide, and a phosphorus containing antiwear component. The borate dispersant may comprise up to 1% by weight of boron. Succinimides can be prepared from alkenyl succinic acids or anhydrides, and ammonia. The phosphorus containing antiwear component may include phosphoric acid, organic esters of phosphorous acid, or their amine salts.

Another embodiment provides a method of improving friction durability comprising adding an additive composition to a base oil. The additive composition may comprise a borate dispersant, succinimide, and a phosphorus containing antiwear component. The borate dispersant may have one or more polyalkylene moieties having a molecular weight of about 900 to about 3000 amu, wherein the borate dispersant comprises up to 1% by weight of boron. Succinimide can be present in a friction adjusting content and can be prepared from alkenyl succinic acid or anhydride, and ammonia. The phosphorus containing antiwear component may include phosphoric acid, organic esters of phosphorous acid, or their amine salts.

The power transmission fluid of the present invention is formulated to deliver improved friction durability, i.e., friction characteristics that hardly change when the fluid is subjected to thermal and oxidative stress. Power transmission fluids of the present invention may be used in high transmission lubricants such as those of ordinary transmissions, such as sleeping torque converters, lock-up torque converters, starting clutches, and / or one or more shifting clutches. It is suitable for use with a transmission. The transmission may comprise a four-, five-, six- or seven-speed transmission, or may include a continuously variable transmission (chain, belt, and disc type). This can also be used for manual transmissions, including automated manual and double-clutch transmissions.

Both the foregoing general description and the following detailed description are exemplary and explanatory only, and are intended to provide further explanation of the invention as claimed.

Since the power transmission fluid operates under harsher conditions, the oil used to lubricate the transmission must be formulated to withstand higher temperatures and pressures. In order to minimize device problems and maximize transmission oil change intervals, the oil additive package should be formulated to change as little as possible when critical oil properties face the pressure. In particular, the friction properties of the oil, which are highly dependent on the additive package, must be kept constant. This ensures smooth engagement of the torque converter and the shifting clutch and minimized vibration, vibration and noise, and improved fuel economy. It has been found that the components disclosed herein impart very improved friction durability to the oil when blended into a base oil having a suitable viscosity.

In one embodiment, the power transmission fluid may comprise a base oil and an additive composition. The additive composition may comprise a borate dispersant, succinimide, and a phosphorus containing antiwear component.
