Abstract
A kind of entitled high transmission efficiency main gearbox assembly of the utility model.Belong to automobile drive axle technical field.It mainly solves the main cone bearing lubrication in existing main reducing gear, when running at high speed because dynamic bevel gear splashing is excessive into the oil mass of oil leab, the problem of making excessive rolling element agitation lubricating oil and produce unnecessary power loss.It is mainly characterized by：Oil duct is equipped with including reducer shell and loaded on the main dynamic bevel gear in reducing gearbox body, main cone bearing, differential assembly, reducer shell；The built-in fuel-economizing plug for being useful for adjusting lubricants capacity of the oil duct.The utility model is mainly used for main reducing gear of drive axle assembly, and reducing dynamic bevel gear by the fuel-economizing plug of reducer shell splashes into the lubricants capacity of oil duct, and reduce lubrication object main cone bearing stirs oily power loss, so as to reach the effect of lifting transmission efficiency.
Description
Technical field
The utility model belongs to automobile drive axle technical field, more particularly to a kind of main reducing gear of drive axle assembly.
Background technology
Drive axle is the crucial power assembly of automobile, and main reducing gear is the kernel component of drive axle, and being mainly responsible for send out
The moment of torsion of motivation output is delivered to driving wheel.When vehicle is run, main reducing gear can bring power to damage while moment of torsion is transmitted
Lose, normally behave as the mechanical output loss of driving parts and each parts stir the power damage that lubricating oil is brought in operation
Lose, the bearing lubrication especially in main reducing gear, when running at high speed because dynamic bevel gear is splashed into the oil mass of oil leab
It is excessive, excessive rolling element is stirred lubricating oil and is generated unnecessary power loss.
Increasingly lifted now with requirement of the market to vehicle fuel economy, the transmission effect of each dynamical system assembly of vehicle
Rate becomes one of important characteristic index, and the fuel economy of vehicle can be improved by improving the transmission efficiency of driving bridge main reducing, that
How to reduce the power loss of main reducing gear becomes a new technical barrier.
The content of the invention
The purpose of this utility model is that the oily power that stirs produced in the running to reduce main reducing gear of drive axle assembly damages
Lose, so that a kind of high transmission efficiency main gearbox assembly proposed.
To achieve these goals, the utility model employs following technical solution：A kind of high transmission efficiency main reducing gear
Assembly, including reducer shell and loaded on the main dynamic bevel gear in reducing gearbox body, main cone bearing, differential assembly, slow down
Device housing is equipped with oil duct, it is characterised in that：The built-in fuel-economizing plug for being useful for adjusting lubricants capacity of the reducer shell oil duct.
Oil duct described in the technical solution of the utility model includes the gear lubrication oil duct in reducing gearbox body,
A cylindrical receptacle that can be used for assembling fuel-economizing plug is cast with gear lubrication oil duct, there are two one on the hole wall of cylindrical receptacle
Font card slot；Fuel-economizing plug is equipped with one beyond the Great Wall with two yi word pattern cutting ferrules coordinated respectively with two yi word pattern card slots, fuel-economizing
It is used to fill into the through hole of lubricants capacity in reducing gearbox oil duct and one to splash for adjusting to rotate by dynamic bevel gear
The sleeve matched somebody with somebody.
The diameter of through hole described in the technical solution of the utility model is between 8-14mm.
The utility model due to reducer shell oil duct it is built-in be useful for adjust lubricants capacity fuel-economizing plug, thus, this
Utility model can only determine lubricants capacity by reducer shell oil leab cross-sectional sizes compared with prior art, by traditional
Main gearbox assembly be altered to a kind of adjustable main gearbox assembly of lubricants capacity.
The advantages of the utility model：Driven wheel of differential is reduced by the fuel-economizing plug of reducer shell to splash into the profit of oil duct
Lubricating oil amount, reduce lubrication object main cone bearing stirs oily power loss, so as to reach the effect of lifting transmission efficiency.
