Driveline

Focus components from the clutch and gearbox sector

Gearbox housing

Gearbox housing

The gearbox housing is the central component in the driveline. This is where the engine power is efficiently transferred to the wheels. This component, usually made of aluminium for passenger cars and cast steel for commercial vehicles, requires the highest precision during production. The strict tolerance specifications on the drive and output side guarantee functionality. Depending on the type of transmission, the housing shapes vary from compact transmission housings to tunnel-shaped transmission housings for multi-stage automatic transmissions. Current trends towards electric and hybrid drives also mean a high demand for transmission housings in the future and continuous further development of the components.

Highlight machining:

• Main cable and torque converter bore
• Output and differential bearing bore
• Parking lock bore
• Bearing bore

Valve and gate valve housing

Valve and gate valve housing

In the automotive sector, the trend is increasingly moving towards automatic transmissions. Together with the shift and control sliders, the gear changes are automatically actuated and controlled in the valve and slider housing. Due to their labyrinthine design, the housings are very unstable. The components, which are usually made of aluminium alloys, are generally subject to very tight manufacturing tolerances in order to ensure clean and fast gear changes.

Highlight machining:

• Valve and slide valve bore
• Pressure regulator bore
• Plug bore
• Face milling of the surfaces

Switching and control slider

Switching and control slider

Shift and control sliders are an integral part of the valve and slider housing in automatic transmissions and make a decisive contribution to precise gear control. The production of the component must meet the highest standards in order to ensure freedom from wear and accuracy of fit.

Highlight machining:

• External machining of the cylindrical surfaces

Planet carrier

行星齿轮架

现代自动变速器由多达三个独立的行星齿轮组成，其中行星齿轮架容纳齿轮/行星齿轮并将扭矩直接传递到驱动轴。旋转行星齿轮通常为三个或四个，通过卫星孔支承，这对质量要求特别高。在汽车领域，这些部件采用不同的加工策略并且是由铝板或锻钢全自动制造的。

• 轴承孔 

差速器壳体

差速器壳体

差速器壳体是动力系统中不可缺少的部件，位于从动轴的中部。它确保车轮在转弯时以不同的速度转动，但提供相同的推进力。差速器独立于驱动装置，安装在传统的的内燃机、混合动力发动机和电动机中，这也体现在数量增加的批量上。在生产高度复杂的铸铁部件时，制造商注重生产节拍时间和工艺可靠性。 
 
亮点加工： 

• 驱动孔 
• 从动孔 
• 球形盖加工（壳体内部） 
• 平面加工（壳体内部） 

属于驱动技术领域的聚焦部件

驱动轴

驱动轴

驱动轴的作用是将发动机的扭矩从变速器或差速器传递到车轮上。由钢或合金钢制成，以工艺可靠的方式生产高表面质量和圆度是非常重要，以便以低摩擦和无噪音传递扭矩。 
 
亮点加工： 

• 密封面的无扭转削皮切削（无进料沟痕） 
• 具有高承重比率的轴承座

等速万向节头

等速万向节头

等速万向节头安装在每辆车的车轴上。它们确保两轴之间扭矩和角速度的一致传递 - 即使存在显着的角度偏差。它们还可以补偿路面的不平。它们的毛坯件经过预锻造或软加工以形成球轨。 
 
亮点加工： 

• 球轨用于内圈和外圈 
• 球轴承保持架外轮廓、内轮廓和视窗
