Transmission Oil Pump

Since the power of the mechanical oil pump comes entirely from the engine, if we turn off the engine while the vehicle is running, the components in the gearbox will not be fully lubricated and cooled, thereby damaging the gearbox. DARE AUTO is a worldwide known transmission oil pump manufacturer in China, mainly supplying automotive and transmission OEMs...

Function of transmission auxiliary oil pump: Mechanical oil pump includes external gearing, internal gearing and vane pump according to its internal structure. It is the core component and power source in the automatic transmission system, mainly providing the transmission a certain flow and pressure to realizes functions such as start-stop, gear shifting,...

About Transmission System: Automatic transmission, especially the transmission with electro-hydraulic control, all actions are mainly realized through the control of the hydraulic system. As an important part of the hydraulic system, transmission oil pump is the heart of the hydraulic system, which can provide a steady stream of power for the hydraulic...

Mechanical oil pump+electric auxiliary oil pump The mechanical oil pump+electric auxiliary oil pump is also known as a dual pump system. Due to the fact that the power and flow requirements of the gearbox for hydraulic oil vary from time to time based on the load, with peaks and valleys. When there is only a mechanical oil pump, the mechanical oil pump will...

Involute type pump with crescent partition Figure 1 shows an involute internal meshing gear pump with a crescent shaped partition, with a pressure angle of 20-30 degrees for the involute tooth shape. The center of the driving outer gear and the driven inner gear is arranged eccentrically. Due to the difference in the number of teeth between the driving gear...

Electric oil pump As the capacity and voltage of the on-board battery gradually increase, the degree of electrification of the transmission oil pump will further deepen, especially in plug-in hybrid vehicles. As the engine only intervenes when necessary, most of the time it is driven by pure electricity, and at this time, the Lubrication Oil Pump takes on...

Automatic transmission oil pump classification According to whether the displacement of the oil pump can be changed, automotive automatic transmission oil pumps can be divided into quantitative pumps and variable displacement pumps. Common definitions The metering pump has two types: external engagement and internal engagement. On construction machinery and...

Automatic transmission oil pump The design requirements for automotive automatic transmission oil pumps are: to meet the pressure and flow requirements, the volume should be as small as possible, the energy consumption should be as low as possible, the noise should be as small as possible, and the reliability should be as high as possible. The oil pumps...

Function of transmission auxiliary oil pump The transmission auxiliary oil pump is the heart of the transmission oil. When the transmission oil circulates to the bottom, it can pressurize the oil from the bottom through the filter screen to the top. The following is the role of the engine oil pump: 1. Send engine oil to various friction parts of the engine...

With the development of automotive energy saving technology and hybrid technology, the requirements for the working efficiency, control accuracy, and energy consumption level of the oil pump in the gearbox have continuously improved. The transmission oil pump has developed from a traditional mechanical oil pump to a dual pump system, and an electric oil...

Automatic transmission oil pump In the early stages of the development of automatic transmissions, dual pumps were used in automatic transmissions. They were used to transfer the front and rear of the transmission, with the front pump driven by the engine and the rear pump driven by the output shaft. The function of the rear pump is to maintain the...

Automatic transmission oil pump The Lubrication Oil Pump is the power source of the entire hydraulic system of an automatic transmission, and is generally directly driven by the engine. All automatic transmissions have a front pump driven by the engine, and some transmissions also have a rear pump driven by the output shaft. The functions of these two pumps...

Automatic transmission oil pump The automatic transmission oil pump, also known as the gear pump, plays a very important role in the automatic transmission and is one of the most important assemblies of the automatic transmission. The oil pump is installed at the rear of the hydraulic torque converter and driven by the shaft sleeve at the rear of the...

The transmission oil pump is the heart of the transmission oil. When the transmission oil circulates to the bottom, it can pressurize the oil from the bottom through the filter screen to the top. The following is the role of the engine oil pump: 1. Send engine oil to various friction parts of the engine to circulate the oil on the lubrication channel to...

The function of the oil pump of the transmission is to provide hydraulic pressure to operate the control valve and clutch, provide a quantitative supply of gear oil in the transmission and differential boxes, and send the transmission oil to the cooler for circulation and heat dissipation. The following is a partial introduction to the oil pump: The oil...

DARE AUTO is able to design the pump and software according to Customer’s technical specifications. With a robust global engineering team, DARE AUTO is able to provide customized solution. Critical parameters: Gear pump:...

Automatic transmissions, especially those with electrohydraulic control as the main means, are controlled by the hydraulic system during their operation. As an important component of the hydraulic system, the oil pump is the heart of the hydraulic system, providing a continuous stream of power for the hydraulic system, providing hydraulic oil for components...

Mechanical oil pump Currently, most traditional automatic transmissions use mechanical oil pumps, such as the Volkswagen DQ380 transmission. The power of the mechanical oil pump comes from the engine. As long as the engine is running, the automatic transmission oil pump is in operation and outputs pressure oil. The mechanical oil pump of an automatic...
