Original spare part of the adjustable ball differential, front or rear, of the Atomic BZ2017 chassis.

This differential is identical to the ones originally supplied in the Atomic BZ2017 kit. It is supplied assembled, ready to work. It is recommended that it be adjusted at the pilot's will.

¿What is an adjustable ball differential?

This is a mechanism that manages that the wheel on one side rotate more or less turns than the wheel on the other side of the same train, and also, being adjustable, we can soften or harden at our will. It works with ceramic balls inserted in the crown (in the case of the Atomic BZ this crown is a pulley, since it receives the power of the transmission belt) and with some plates or tracks that press these balls. Tightening the differential means that the tracks press more on the pulley balls and therefore the differential assembly will have a tougher feel. There is virtually no loss of power (the differential releases and transmits the same power that receives the wheels of the car), and the differential effect (one wheel rotates more than another) disappears slightly (the two wheels of the same train tend to turn the same turns). If on the contrary we work with a loose, loose, soft touch differential, we will suffer a slight loss of power since the differential assembly will act as a clutch. This is ideal for sliding surfaces or tracks with little grip. The tracks, the balls and the crown of the differential, at the moment in which we accelerate the engine of the car thoroughly, will not transmit all the power that comes from the transmission to the wheels. In addition to assuming part of the power the differential will distribute the power between the two wheels of the same train to facilitate the turns of our chassis.

So, playing with the tightening of the two differentials, we can adjust the traction of our car, and achieve, for example, that drag more forward (differential slightly tightened) and that the differential of the rear train facilitates more the turn, making a good differential effect and at the same time clutch (skating gently to avoid pushing too much).

All these adjustments will depend to a great extent on the traction of the circuit, on the tires that we use, and of course, on the driving style of each one.

& iquest What is the difference between this differential and the chassis model BZ2016?

The only difference between this differential for the BZ2017 chassis with the differential used by its predecessor is the double lip. This differential has a double wall or double lip, to ensure that the strap is much better centered and does not jump in case it comes off or goes to the sides. The previous version only had a side wall.
