What is hub reduction?
The hub reduction consists of a cylindrical planetary gear with straight needle bearing gears, which gives small loss-es. The sun gear is mounted on the driveshaft and the driving power is transferred from it to the four planetary gears that are connected to the wheel hub.
Why do hubs reduce?
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 meant by hub reduction axle?
Hub-reduction axles – also known as planetary axles – split the torque between the differential and the planetary gears in the wheel hubs. In addition, vehicles fitted with hub-reduction drive axles have the benefit of offering better ground clearance, making them well suited to applications involving rough terrain.
Why do manufacturers use hub reduction units?
Hub reduction gears reduce loads on the driveline. Wheel bearings in the form of maintenance-free unit bearings give longer life and easier servicing. Three reliable diff locks give high vehicle availability. High ground clearance.
What is a Scania hub reduction?
Scania is also introducing a new specialist feature for the Opticruise transmission — Clutch-on-Demand. In the XT, Scania has switched to helical gears for hub reduction, which contributes to both a reduced noise level and increased service life.
What is a 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.
What is the advantage of hub reduction axle?
This gives two advantages: ground clearance is increased, particularly beneath the low-slung differential housing of the main axles — and secondly, any hub reduction gearing allows the axle halfshafts to drive the same power but at reduced torque (by using higher shaft speed).
What do Portal gears do?
Portals, or portal gear lifts, allow you to lift your vehicle and provide gear reduction to run larger tires, gain torque, and keep your factory steering geometry. Adding a standard lift can cause you to do extensive work to change the gear ratio.
What is single reduction?
Single Reduction gear This arrangement consists of only one one pair of gears. The reduction gear box consists of ports through which the propeller shaft and engine shaft enters the assembly. A small gear known as a pinion is driven by the incoming engine shaft.
What is tru Lok?
The low-pressure, air-locked Tru-Lok differentials allow the driver to lock the front and rear axles from a switch on the dashboard, a first for Jeep vehicles. While both front and rear differentials are called Tru-Lok, only the rear functions as a limited slip when not in the locked position.
What is the definition of a food hub?
According to the USDA’s Regional Food Hub Resource Guide, a food hub is a “business or organization that actively manages the aggregation, distribution, and marketing of course-identified food products primarily from local and regional producers to strengthen their ability to satisfy wholesale, retail,…
What makes a hub reduction axle hub reduction?
A hub reduction axle, as has been explained well in earlier responses, is additional gear reduction at each wheel hub of an axle – hence, “hub reduction”.
Why are food hubs important for Rural Development?
Food hubs as rural development Food hubs represent a strategy for producers, par- ticularly small and mid-sized producers, to market their production locally. Food hubs create new marketing opportunities for rural food producers.
What can food hubs do for food deserts?
Nearly 40% of food hubs focus on increasing access to fresh foods in food deserts and other under-served areas. For consumers who already feel they have good access to local foods, a food hub can make the process much more convenient.
