What is a double reduction axle?
A 2 speed axle has 2 different gear ratios you can choose from with a selector switch. A double reduction is just that, a ‘double reduction’. It has essentially 2 gear reductions between the input and the output. This method only has one over all ratio though, between the input and the output.
How does a hub reduction axle work?
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.
Which of the following is a benefit of a double reduction drive axle?
Double reduction drive axle has big advantage for not good road condition. It gets higher passability and bigger output torque.
What is double reduction?
Double reduction occurs when sister alleles migrate to the same gamete during meiosis. It depends on the frequency at which a locus recombines with its centromere, and on the frequency of multivalent formation.
What is the advantage of hub reduction axle?
One advantage of a hub reduction or planetary drive rear axle is that the input torque gets reduced twice. First in the differential centre and then through the planetary drive wheel ends. Another advantage, especially for trucks like this one that operate out of mines and quarries, is the high ground clearance.
What is the advantage of hub reduction?
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.
How does reduction gear work?
A reduction gear is an arrangement by which an input speed can be lowered for a requirement of slower output speed, with same or more output torque. Reduction gear assembly consists of a set of rotating gears connected to a wheel work.
When a small gear drives a large gear?
If you use a small gear to drive a large gear, the large one will turn slower. fast speed, we use it to move the large one. gear turn more slowly.
Why do manufacturers use hub reduction units?
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. Requirements on size and packaging has been considered.
Are portal axles worth it?
Portal axles can help increase the off-road capability of a vehicle because they maintain the manufacturers original suspension geometry. This means you can get significant lift while maintaining close to the handling of a stock vehicle.
Does gear reduction increase torque?
While in many applications gear reduction reduces speed and increases torque, in other applications gear reduction is used to increase speed and reduce torque.
Why do lower gears have more torque?
Within the capability limits of the engine, shifting into a lower gear allows the engine to turn faster, allowing it to produce more power which the transmission converts into greater output torque for a given wheel speed.
What is meant by a 6×2 truck?
6×2 Rigids This means that you now have six wheels on the ground, but still only two of them are driven by the gearbox – or a 6×2. A 6×2 ‘rigid’ truck (one that isn’t towing a trailer) can therefore weigh 8 tonnes more than a 4×2 truck – or 26 tonnes GVW.
Do portal axles increase torque?
The portal axle is an off-road technology which is designed to provide higher ground clearance and increased torque at the wheels.
What is the point of portal axles?
What are the advantages of double reduction axle?
Double reduction axle resolve this conflict perfectly by installing a speed reducing gear between the axle shaft and the wheel. In this way, the basin gear of main speed reducer becomes smaller and the truck passability is improved. This is why double reduction axle could deal with more complicated road condition.
How does a double reduction gear work?
However in case of double reduction mechanism, the reduction of speed takes place in 2 steps. Initially the input from the engine shaft has a pinion mounted on it through couplings. This pinion gear is then connected to an intermediate gear which is first reduction gear.
How does a double reduction mechanism work?
However in case of double reduction mechanism, the reduction of speed takes place in 2 steps. Initially the input from the engine shaft has a pinion mounted on it through couplings. This pinion gear is then connected to an intermediate gear which is first reduction gear. This gear is then connected to another low speed pinion on another shaft.
What is a double reduction pinion?
A double reduction is just that, a ‘double reduction’. It has essentially 2 gear reductions between the input and the output. This method only has one over all ratio though, between the input and the output. Hope this makes sense… The pinion drives an intermediate gear which drives the big bull gear, so two reductions… I see.
