A tag axle is a third axle located persist the rear handle axle of a Engine internal. It is a non-drive axle with one or two tires on Everyone side. The leading destination of a tag axle is to boost the flotation of the chassis at the rear of the vehicle, allowing for in a superior way carrying authority and shock resistence.
Additional Carrying Capacity
A motor home with a tag axle Testament arrange in a superior way carrying potency than a single-axle, generally resulting in a 10,000 to 20,000 pound augmentation. A tag-axle Engine habitat Testament keep a higher quality haul carrying competence than a single-axle Engine inland of comparable vastness and faculty. Additionally, the Appendix of a tag axle allows for the interpretation of larger Engine homes than single-axle designs, providing augmented amplitude for the occupants.
This reduces the likelihood of the rear chassis coming into contact with the ground when navigating steep inclines or uneven terrain.
Reduced U-Joint Wear
The addition of a tag axle pushes the drive axle further forward on the chassis.Increased Rear Chassis Support
The tag axle provides greater support for the rear chassis, adding an extra set of shock absorbers and spreading the load across a larger section of the chassis. Moreover, the tag axle is generally located farther to the rear of the chassis than a single axle, decreasing the leverage of the chassis extending past the rear axle.The engine of most motor homes is located behind and above the rear axle. The greater distance between the motor and the drive axle results in a shallower angle for the drive shaft, allowing it to create a more nearly level connection between the drive shaft and the drive axle. This reduces the strain on the U-joint, thereby reducing wear.
Additional Braking Power
While the tag axle is not connected to the motor, modern tag axles are often equipped with brakes. An additional braking axle greatly increases the traction and stopping distance for a motor home of equivalent weight. The ability to make sudden decelerations and stop more quickly is both a convenience to the driver and an important safety consideration.
