Aluminium cups for central driveshaft

Aluminium Cups for Central Cardan Shaft: Solid and Precise Transmission

When on-track performance depends on every tenth, transmission components make the difference. These aluminium cups for the central cardan shaft are made from aluminium, a material that combines lightness and strength, reducing rotating mass and contributing to a smoother and more direct transmission.

Function and Performance

The central cardan shaft is the system responsible for transmitting the motor's rotation to the drive axle when both are not aligned in the same plane. The cups are the parts that house and articulate that connection, and their quality directly influences the smoothness of the transmission, the absence of vibrations, and the car's response to speed changes.

Being made from aluminium, they offer:

• Lower rotational inertia compared to parts made from heavier materials.
• Good dimensional tolerance, resulting in a precise fit with no play.
• Durability suitable for continuous use sessions, both in club racing and competition preparation.

Assembly and Preparation

For correct assembly, it is essential to verify that the dimensions of the cup are compatible with the cardan and axle of your car before installation. A fit that is too loose will generate vibration and loss of efficiency; an excessively tight fit may hinder the correct articulation of the system.

We recommend thoroughly cleaning the mounting area, checking the alignment of the cardan-axle assembly, and, if indicated by the manufacturer, applying a minimal amount of specific slot transmission lubricant at the contact points.

Ideal for…

• Preparers looking to optimise the drivetrain of their cars.
• Club competitors seeking to eliminate sources of vibration and improve power response.
• Enthusiasts who perform their own chassis assembly and maintenance.

Considerations

Before purchasing these cups, confirm compatibility with the central cardan of your chassis. Dimensions and coupling types may vary depending on the manufacturer and model. If in doubt, consult us before placing your order.

Frequently Asked Questions

What exactly is a central cardan cup?

It is the part, generally cylindrical or hemispherical, that houses one end of the cardan transmission shaft. It allows for angular articulation between the motor and the drive axle, absorbing small misalignments without losing efficiency in the transmission of rotation.

Why use aluminium cups over other materials?

Aluminium offers a good balance between weight and strength. By reducing the mass in rotating parts, inertia is decreased, and the response of the drivetrain is improved, particularly noticeable during acceleration and braking.

Do I need special tools for assembly?

In most cases, standard slot preparation tools are sufficient: precision screwdrivers, fine-tipped pliers, and occasionally, an axle extraction tool. Check the specific instructions from your chassis manufacturer.

What traction systems is this type of part compatible with?

Central cardan cups are specific to assemblies with cardan transmission, common in 1/32 and 1/24 scale competition chassis. Exact compatibility depends on the chassis manufacturer: always verify the measurements before installation.

Are they sold individually or in packs?

The sales format is indicated in the reference YETT022BU. Check the product sheet or contact us if you need confirmation before placing your order.
