Abstract
The utility model discloses a kind of automobile drive axle breather, it comprises breather pipe body (1) and end cap (2), be characterized in, in described breather pipe body (1), establish stepped hole (11), breather pipe body (1) and end cap (2) free-running fit, and by the fixing end cap (2) of the boss (13) on breather pipe body (1), the termination that breather pipe body (1) coordinates with end cap (2) is provided with air channel (12), balance inner and outer air pressure; Under severe service conditions, can effectively prevent oil impregnate, leakage of oil, good dustproof effect, failure rate is low, the mileage of guaranteeing is longer, reduces and uses car maintenance cost simultaneously.
Description
Technical field:
During the utility model relates to, heavily card and road transport vehicle parts technical field, be a kind of automobile drive axle breather concretely; In being applicable to, heavily card and road transport vehicle.
Background technology:
Along with the development of auto-industry, in, heavily card and road transport vehicle have entered the high speed development stage, in, heavily card and road transport vehicle be to high bearing capacity, high performance requirements and the long as far as possible mileage number future development of guaranteeing.The breather pipe using at present exists following not enough: 1, under severe service conditions, easily produce oil impregnate, oil leakage phenomenon; 2, dust-proof effect is poor, and fault rate is high, and the mileage number of guaranteeing is few; 3, easily cause that lubricating oil runs off, dust pollutes, cause vehicle bridge driving system to damage, increase and use car maintenance cost.
Utility model content:
The purpose of this utility model is the deficiency that overcomes above-mentioned technology, and a kind of automobile drive axle breather is provided; Mainly solve the problem that under existing breather pipe bad working environments, lubricating oil oil leak pollutes, fault rate is higher and the mileage of guaranteeing is short.
The technical solution of the utility model is: a kind of automobile drive axle breather, it comprises breather pipe body and end cap, its special character is, in described breather pipe body, establish stepped hole, breather pipe body coordinates with end cover clearance, and by the fixing end cap of the boss on breather pipe body, the termination that breather pipe body coordinates with end cap is provided with air channel.
Compared with the prior art a kind of automobile drive axle breather described in the utility model has following good effect: 1, under severe service conditions, can effectively prevent oil impregnate, leakage of oil; 2, good dustproof effect, failure rate is low, the mileage of guaranteeing is longer; 3, reduce and use car maintenance cost.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is breather pipe pipe structure schematic diagram of the present utility model;
Fig. 3 is the birds-eye view of Fig. 2;
Fig. 4 is end cover structure schematic diagram of the present utility model.
The specific embodiment:
For Comprehension and Implementation better, below in conjunction with accompanying drawing, provide specific embodiment and describe a kind of automobile drive axle breather of the utility model in detail; Illustrated embodiment is only for explaining the utility model, not for limiting scope of the present utility model.
Embodiment 1, referring to Fig. 1,2,3,4, according to design, need to be processed into breather pipe body 1 and end cap 2; Breather pipe body 1 inside is provided with 2 stepped holes 11, in order to reach reducing object, when high vehicle speeds lubricating oil splash is to breather pipe body 1 bottom, when the inner generation of tube wall oil film, because high vehicle speeds can produce at the breather pipe mouth of pipe place negative pressure, make oil film increase, touch stepped hole 11, oil film reducing, because surface tension deficiency just can be broken, lubricating oil flows down along breather pipe tube wall, prevents oil leakage; There is air channel 12 termination that breather pipe body 1 matches with end cap 2, prevents airtightly, reaches the object of ventilation; Breather pipe body 1 and end cap 2 free-running fits, in order to reach ventilation and dustproof effect, the negative pressure that in the time of can reducing to run at high speed, mouth of pipe place produces simultaneously, prevents oil leakage, and by the fixing end cap 2 of the boss 13 on breather pipe body 1.
