What's The difference Between Single Reduction Axle and Double Reduction Axle ?

The characteristics of the axle directly affect the vehicle's drivability and fuel consumption performance and are an integral part of all trucks. Currently, there are mainly single reduction axle and double reduction axle, what are the advantages, disadvantages and differences between these two types of axles? What are the advantages, disadvantages and differences between these two types of axles? This article will introduce them to you in detail.

 

 

1. Single Reduction Axle

 

a. Introduction: A single reduction axle is an axle with only one set of gears in the middle, i.e., the main reduction gear, which is used to reduce speed and increase torque. The use of single reduction axle tractor trucks is very popular in countries where there are restrictions on the weight of vehicles to be transported, such as Tanzania, Zambia, Mozambique and other East African countries.

 

b. Disadvantages: This type of axle has a larger diameter of large gears and therefore a larger center of the axle, which affects the passability of the vehicle. The torque amplification is insufficient and it is only suitable for lightweight transport and only on road transport with good road conditions.

 

c. Advantage: Single reduction axles have slightly smaller speed ratios, are faster and more efficient for long-distance transport. The axle structure is simple, easy to maintain and has a low failure rate. The corresponding axle weight is also lighter, suitable for lightweight transport.

 

 

2. Double Reduction Axle

 

a. Introduction: Compared with the single reduction axle, there is an additional set of reduction drives at the wheel. This type of axle through the two-stage transmission to achieve the deceleration ratio, the middle of axle is smaller than the single reduction axle. Most heavy duty dump trucks and heavy duty tractor trucks use this type of axle.

 

b. Disadvantages: Due to the extra one-stage transmission, the mechanical efficiency is reduced, energy loss is more, and it is more fuel-consuming. The heat dissipation effect of the wheel end is poor, which is easy to induce tyre burst accident, so it is not suitable for long time and long distance high speed transport.

 

c. Advantage: The middle of double reduction axle is smaller, which improves the vehicle's drivability. Dual-stage axle can withstand greater input torque, suitable for poor road conditions, heavy load or even overloading, strong driving force, and strong climbing ability.

 

 

Overall, single-stage reduction axles and double reduction axles have their own strengths, and TRUCKMAN, as a professional truck dealer, will take into account the actual transport scenarios of its customers and recommend suitable and durable axles, so as to achieve higher fuel economy and maximise benefits.
