AT automatic transmission products

An automatic transmission is a transmission device that can automatically shift gears according to the vehicle speed and engine speed, in contrast to a manual transmission. Currently, there are four common types of automatic transmissions: hydraulic automatic transmission (AT), mechanical continuously variable transmission (CVT), electronically controlled mechanical automatic transmission (AMT), and dual-clutch automatic transmission. The core of an automatic transmission is the automatic shifting function. Automatic shifting means that during driving, the driver operates the accelerator pedal according to driving needs, and the automatic transmission automatically selects different gears based on engine load and vehicle operating conditions.

Bimetallic bushing gear series

Gears are mechanical components with teeth on their rims that mesh continuously to transmit motion and power. The application of gears in transmission appeared very early. At the end of the 19th century, the principle of generating gear cutting and the successive appearance of special machine tools and cutting tools using this principle, along with the development of production, led to increased importance being placed on the smooth operation of gears. Domestically produced, medium and low-end gear molds are widely available, while high-end gear molds are mostly imported. There are few factories in China that specialize in gear molds; most gear factories make their own molds, often assigning a section or workshop to this task. This makes the development of China's gear mold industry even more difficult. Relevant experts suggest that to promote the faster and better development of China's gear mold industry, it is necessary to fundamentally solve the problem of reliance on imports and strive to improve professional technology in order to better serve the domestic gear mold industry.

Synchronizer component

Older gearboxes required a "double-declutching" method for shifting gears. Upshifting required a brief pause in neutral (but with the clutch raised, to allow the clutch plates and flywheel to synchronize, requiring matching speeds for smooth gear changes. If the shift was slow, and the speed dropped to idle, it would be impossible to engage the next gear). Downshifting required a pause in neutral (with the clutch raised) while giving the engine gas, to reduce the difference in gear speed. This operation was complex and precise, thus, the creation of the "synchronizer" which matches the speed of engaging gears to allow smooth meshing.

Qingshan DCT products

DCT differs from a typical automatic transmission system. It's based on a manual transmission but is not an automatic transmission. In addition to offering the flexibility of a manual transmission and the comfort of an automatic transmission, it also provides uninterrupted power output. The DCT's driveshaft movement is divided into two parts: a solid driveshaft and a hollow driveshaft. The solid driveshaft connects gears 1, 3, 5, and reverse, while the hollow driveshaft connects gears 2, 4, and 6. Two clutches are responsible for the engagement of each driveshaft, allowing the engine power to be transmitted uninterrupted by one of the driveshafts.

Transmission shaft teeth

Transmission gears frequently operate under conditions of high speed, high load, and constantly changing speed and load. In addition to normal wear and tear, gear damage can also be caused by poor lubricant quality, poor lubrication conditions, improper driving operation, and improper gear meshing during maintenance. These factors can lead to gear impact, poor tooth meshing, and start-up vibration, all of which accelerate gear wear and damage. Gears rely on their structural dimensions and material strength to withstand external loads, requiring materials with high strength, toughness, and wear resistance. Due to the complex shape and high precision requirements of gears, the materials must also have good processability. Forged steel is commonly used for transmission gears.
