Abstract
The utility model discloses a gearbox and drive axle structure with a novel lubrication system, comprising a gearbox and a drive axle assembly; a gear pump is arranged on the gearbox; an oil inlet end and an oil outlet end of the gear pump are respectively communicated with the bottom and the top of the gearbox; another gear pump is fixed on the front cover of a retarder and differential assembly; and an oil inlet end and an oil outlet end of the gear pump are respectively communicated with the bottom and the top of the front cover of the retarder and differential. Through the utility model, the abrasion speed of the improved component is markedly improved, so that the running life of the gearbox and the drive axle assembly is greatly prolonged; and furthermore, the structural design is reasonable and improved on the basis of existing technologies, so that the implementation is easy.
Description
Technical field
The utility model relates to the automotive driving system technical field, is specially a kind of change speed gear box and drive axle structure with novel lubricating system.
Background technology
Present automobile, the change speed gear box of engineering truck and drive axle assembly place all are not provided with lubricating oil pump; The employing passive mode is lubricated; Internal gear oil content cloth is inhomogeneous, and lubricant effect is not good, especially is that heavy duty truck, engineering truck are because interactional parts application force is big; Component wear is very fast, and maintenance cost is higher; Secondly, gear oil long-term use meeting contains more solid impurities, influences its mobility and lubricity, must frequent replacing gear oil, not only delay car owner's time, and also increased car owner's use cost.This shows the lubricating method that improves change speed gear box and drive axle, be initiatively lubricated, and can the gear well cuts be in time cleared up, is to reduce component wear, the important means that prolongs change speed gear box and drive axle service life.
The utility model content
For overcoming above-mentioned technical matters, the utility model provides a kind of positive lubrication function that has, and change speed gear box and the drive axle structure that can filter gear oil.
For realizing above-mentioned technical purpose; The utility model is to adopt following technical scheme to realize: a kind of change speed gear box and drive axle structure with novel lubricating system; Comprise change speed gear box and with its through the drive axle assembly that transmission shaft links to each other, it is characterized in that: gear-box axle covers and is fixed with a gear type pump, extended axle links to each other on gear type pump and the shaft-cup; Its oil inlet end communicates with the change speed gear box bottom, and its oil outlet end communicates with the change speed gear box top through machine oil filter core, centrifugal filter rotor block assembly; The difference of drive axle assembly front side subtracts and is fixed with a gear type pump on the assembly protecgulum; Gear type pump links to each other with the rotatable parts that difference subtracts in the assembly through adapter shaft; Its oil inlet end subtracts assembly protecgulum bottom with difference and communicates, and tops communicates its oil outlet end through machine oil filter core, centrifugal filter rotor block assembly and before difference subtracts assembly.
Described gear type pump is fixed through the gear pump seat.
The gear type pump that described gear-box axle covers links to each other with tween drive shaft.
Machine oil filter core on the described change speed gear box, centrifugal filter rotor block assembly are fixed in gear box casing one side through oil strainer core print seat, centrifugal filter rotor block seat respectively.
Machine oil filter core on the described drive axle assembly, centrifugal filter rotor block assembly are fixed in difference through oil strainer core print seat, centrifugal filter rotor block seat respectively and subtract the housing assembly top.
The utlity model has following beneficial effect: owing to all installed gear type pump additional on drive axle assembly and the change speed gear box; Can carry out positive lubrication to inner kinematic mechanism; And gear oil filters through the impurity that machine oil filter core, centrifugal filter rotor block assembly will be taken turns in the oil in cyclic process; The assurance gear oil is fine and smooth, so that play good lubricity, has prolonged the replacing time of gear oil; The rate of wear of improving back part is significantly improved, and takes away the part heat in the gear oil cyclic process, has improved the running life that change speed gear box and difference subtract assembly greatly; In addition, its reasonable in design is improved on prior art, implements easily.
