Pusher Vs Tag Axle: One of the Main Differences Between Volvo B9R and Volvo B11R
One of the most visually distinctive differences between the Volvo B9R and the Volvo B11R is the position and functionality of their third axles.
The Volvo B9R features a pusher axle, positioned in front of the main drive axle, similar to the design seen in the Ashok Leyland 15-meter multi-axle bus chassis. These pusher axles, located in front of the drive axles, enhance stability during turns and can increase the load-carrying capacity. Additionally, they contribute to improved efficiency, performance, and stopping distances.
In contrast, the Volvo B11R is equipped with a tag axle situated behind the main drive axle, which is steerable. This tag axle turns in the opposite direction of the front axle, aiding in maneuverability and offering a different dynamic to the vehicle’s handling.
Wrapping it Up
The main difference between Volvo B9R and B11R lies in the length of the bus, engine capacity, and the position of the third axle.
The B9R is an excellent choice for operators seeking a reliable and cost-effective coach for long-distance travel.
In contrast, the B11R is ideal for those looking for a high-performance, luxurious bus with advanced safety and comfort features. Potential buyers should consider their specific requirements and budget when choosing between these two models.
