What is single reduction axle?
Single reduction axle has only one speed reducer to control the speed, while double reduction axle has a major speed reducer and a side speed reducing system. Double reduction axle resolve this conflict perfectly by installing a speed reducing gear between the axle shaft and the wheel.
Why is hub reduction used?
The hub reduction should relieve stress on the power- train, increase traction force and reduce speed from the increase in tire size. The gears has been developed, with analysis to give the expected life and low weight.
What is single reduction final drive?
In a single reduction rear axle, rotational speed is reduced in one single step in the final drive, which makes great demands on its components.
What is the carrier on a rear differential?
Carrier – Sometimes referred to as a Differential Case or Ring Gear Carrier. This unit transfers the motion from the ring gear to the axle shafts. Carrier Bearing – These are the bearings that ring gear carriers ride on.
What is reduction hub?
Hub-reduction axles – also known as planetary axles – split the torque between the differential and the planetary gears in the wheel hubs. As the torque is spread over several gear cogs, it makes this design extremely strong and well-suited for extra-heavy-duty work.
How does a 2 speed rear axle work?
The 2-speed axle works on the same basic principles, but with an added planetary gear set inside the ring gear. This works by sliding a clutch gear meshing with the high range clutch plate. When the low range is selected, the sliding clutch gear engages with the low range clutch plate.
What is double reduction?
This is the frequency with which a gamete. receives two alleles derived from the same chromosome at meiosis. The term “double reduction” was first introduced by Darlington. (1929) and defined as a case “where both chromatids of one chromo- some pass into the same nucleus at the second telophase “.
What is a hub reduction?
Hub-reduction axles – also known as planetary axles – split the torque between the differential and the planetary gears in the wheel hubs. Some vehicle operators are of the opinion that vehicles equipped with hub-reduction axles use more fuel than vehicles fitted with single-reduction axles.
What is a double reduction final drive?
For example, a double-reduction final drive might have two gear sets that work together to produce a final gear ratio of 20:1. The torque entering the final drive is multiplied by 20 and the speed is divided (reduced) by a factor of 20.
What’s the difference between single reduction axle and double reduction axle?
Single reduction axle has only one speed reducer to control the speed, while double reduction axle has a major speed reducer and a side speed reducing system. But how should we select regarding the difference between the two?
Where are the bearings in a single reduction carrier?
The single-reduction carriers are front mounted into the axle housing. These carriers have a hypoid drive pinion and ring gear set and bevel gears in the differential assembly. A straight roller bearing or spigot is mounted on the head of the drive pinion. All other bearings in the carrier are tapered roller bearings.
Where are single reduction carriers located on a Meritor?
Standard Single-Reduction Carriers Without Differential Lock Meritor single-reduction standard carriers are used in most Meritor single axles, rear of tandem axles and front drive steer axles. Figure 2.1. The single-reduction carriers are front mounted into the axle housing.
Where can I find information on single reduction differential carriers?
