ASHCROFT ATB

Description

There are a number of other LSD available including the 'plate type' and the Torsen T1, we believe the ATB is superior to the Plate type LSD principally because of the high preload necessary to make the plate type effective, this high pre load leads to 'harshness and vibration effects' and causes high premature wear. The Torsen T1 was the forerunner ATB and relied on a different principle to generate cross torque, effectively using coupled worm and wheel gears, being driven backwards, to create the necessary friction loads. These often failed due to this high loading destroying the worm gears. The helical gear type ATB has many advantages that overcome the objections to other designs. There is a minimal pre-load necessary to engage the gears but this does not cause excessive wear or harshness, the helical gear type is virtually invisible to the driver on normal road use as the gear/pocket friction simply does not occur.

So why use an ATB instead of a locker?? basically when driving on a low traction surface. for example sand, snow, or even wet grass rather than have a locked diff which can 'cause' loss of traction for example when cornering as both wheel are forced to travel at the same speed, one wheel typically breaks traction allowing all the drive to the other wheel which will also break traction. the ATB will allow wheel speed difference but at the same time will always try to equalise the torque to each wheel, this reduces the possibility of a spin out situation.

Product Details

• Fully automatic, needs no driver input

• Totally transparent on road, i.e, no unwanted adverse effects

• Only comes into play when one wheel looses traction, i.e, a difference in wheel speed

• Enhances the traction control as it multiplies the bias load created by the braking effect of the traction control

• Needs no special oils

• Needs no adjustment as the gears compensate for any wear that takes place

• Only with 24 spline side gears

• The ATB, our latest addition, is a 'Helical Gear' type LSD with six gear pockets.

Delivery varies between 2 days and 3 weeks
