The transmission housing assembly is mainly composed of a transmission front housing and a rear housing, which are connected by bolts to form an integral closed structure. In order to ensure light weight, the materials of the front and rear shells are all die-cast aluminum alloy. The transmission housing mainly plays the role of support, enveloping and sealing in the transmission assembly. The function of the housing determines the characteristics of large volume and heavy weight. At the same time, it is required to have high structural strength, rigidity and good NVH characteristics. .

When designing the layout of the housing, under the premise of ensuring the clearance with the internal components, the layout of the components is as close as possible to the outer contour of each component, so that the volume of the transmission can be reduced to the greatest extent, thereby reducing the weight of the housing. Under normal circumstances, the clearance between the housing and gears and other moving parts (machined surface) is about 3mm, and the clearance between the moving parts (non-machined surface) of shift forks and other moving parts (non-machined surface) is 3mm～5mm, and it is fixed to zero with the oil baffle. The part gap is 1mm～2mm..

What is die casting?
Answer: Die casting is abbreviated as die casting. Die casting is the process of using molds and machinery to quickly fill the cavity with liquid metal under pressure, changing from liquid to solid to form the desired product.
What are the types of die casting?
Answer: From the injection chamber method, it can be divided into hot chamber die casting (commonly used for zinc alloy) and cold chamber die casting (commonly used for aluminum alloy). From the pressure, it can be divided into: low pressure casting (such as automobile wheel housing) and pressure casting (such as our company Using pressure casting), from the exhaust method is divided into: ordinary die casting and vacuum die casting.

What are the die casting alloy materials? What are their characteristics?
Answer: Commonly used materials suitable for die casting are: zinc alloy, aluminum alloy, magnesium alloy and copper alloy. They have the following characteristics:
(1) Good fluidity in liquid state;
(2) There are relatively fixed melting and freezing points;
(3) Smaller shrinkage rate;
(4) Has a certain high temperature strength;
(5) It has good processing performance and corrosion resistance.

What are the main components of die-cast aluminum alloy? What are the impurities?
Answer: The main ingredients are: aluminum, silicon, copper, magnesium, manganese, zinc, etc.
Impurities include iron, zinc, copper, tin, aluminum, sulfur, phosphorus, etc.
Different alloy grades have different requirements for their main components and impurity components.
