Abstract
The utility model discloses a vehicle rear-axle connecting flange which has better vibration absorbability and can reduce oil leakage faults of a rear-axle main speed reducer. The vehicle rear-axle connecting flange is used for connecting a rear-axle transmission shaft with the rear-axle main speed reducer. A flange main body of the connecting flange is made from a casting blank, the preferable material of the flange main body is QT700, and the thickness D of the big end of the flange is increased by more than 30% as compared with a flange made of 40Cr forging. With the vehicle rear-axle connecting flange, the vibration of a chassis transmission system can be well reduced, the friction between a main speed reducer oil seal and an input shaft is retarded, so that the oil leakage problem of the rear-axle main speed reducer can be easily improved, and the processing cost of the connecting flange can also be lowered.
Description
Technical field
The utility model relates to a kind of flange arrangement, especially a kind of adpting flange that is used between automobile axle transmission shaft and the rear-end gear reduction.
Background technique
At present, the adpting flange two ends of domestic automobile transmission shaft and rear-end gear reduction are transmission shaft and main reducing gear gear, and both sides all are in the operating mode that runs up, and are the reliability that guarantees to connect, and this adpting flange adopts the forging manufacturing usually, and its material is generally selected 40Cr for use.But because the vibrational energy of transmission system is bigger here, the oil sealing of main reducing gear and the frictional loss between the input shaft strengthen, thereby show as the easy oil leakage of back driving axle main reducing gear.
The model utility content
The absorbing property that existing automobile axle adopts the forging adpting flange to be caused is poor in order to overcome, the deficiency of rear-end gear reduction easy oil leakage, and the utility model technical problem to be solved provides the automobile axle adpting flange that a kind of absorbing property is better, can reduce the rear-end gear reduction oil leakage fault.
The utility model solves the technological scheme that its technical problem adopted: the automobile axle adpting flange, be used to connect rear axle propeller shaft and rear-end gear reduction, and the flange body of said adpting flange adopts the foundry goods base to make.
Further be, the material of said flange body is QT700, and the thickness D of the big end of flange increases more than 30% when adopting 40Cr forging flange.
The beneficial effect of the utility model is: can well reduce the vibration of transmission system of chassis; Reduce the vibrational energy of transmission system; Slow down the main friction that subtracts oil sealing and input shaft, thereby help improving the problem of back driving axle main reducing gear leakage of oil, also can reduce the processing cost of adpting flange.
Description of drawings
Fig. 1 is the plan view of the utility model.
Be labeled as 1-flange body, the thickness of the big end of D-flange among the figure.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As shown in Figure 1, to being used to connect the automobile axle adpting flange of rear axle propeller shaft and rear-end gear reduction, in the utility model; The flange body 1 of said adpting flange adopts the foundry goods base to make; Promptly carry out the blank manufacturing, and then carry out machining, thereby reach processing request with forging type.
Because the tissue of casting material is the spheroidal graphite that distributing in the metallic matrix; Graphite in metallic material has very high weakening property and wear resistance, and with respect to existing forging flange, the foundry goods flange has good absorbing effect; Can well reduce the vibration problem of transmission system of chassis; Owing to reduced the vibrational energy of transmission system, slowed down the main friction that subtracts oil sealing and input shaft simultaneously, showed the problem of back driving axle main reducing gear leakage of oil thereby help improving determining.Adopt after the foundry goods flange, reduced corresponding forging quenching technical in processing link, can reduce the adpting flange processing cost.When carrying out product specification and since foundry goods in tensile strength, plasticity and toughness than forging difference, therefore to recomputate physical dimension according to the flange force status, this belongs to, and those skilled in the art can easily accomplish according to existing technology.
Preferably, the material of said flange body 1 is QT700, and according to claimant's measuring and calculating, main attention this moment need increase the thickness D of the big end of flange more than 30% when adopting 40Cr forging flange, and all the other sizes can remain unchanged.
Claims (2)
1. the automobile axle adpting flange is used to connect rear axle propeller shaft and rear-end gear reduction, it is characterized in that: the flange body of said adpting flange (1) adopts the foundry goods base to make.
2. automobile axle adpting flange as claimed in claim 1 is characterized in that: the material of said flange body (1) is QT700, and the thickness of the big end of flange (D) increases more than 30% when adopting 40Cr forging flange.
