Abstract
The utility model discloses a driving bridge, in particular to a novel driving bridge, wherein a sealing piece on a piston is a Lancaster closure sealing part (1), a wheel side sealing piece in the driving bridge is a Labyrinth sealing ring (2), the outer portion of the Labyrinth sealing ring (2) is provided with a steel sleeve (3), the inner portion of the steel sleeve (3) is provided with hair felt (4), the wheel side of the driving bridge is connected by a bolt (5) and a nut (6), and the steel sleeve (3) is arranged between the bolt (5) and the nut (6). The novel driving bridge has the functions of long life and excellent sealing performance, and increases the strength.
Description
Technical field
The utility model relates to a kind of ransaxle, is specifically related to a kind of novel ransaxle.
Background technique
Ransaxle commonly used at present, its sealing mechanism is used the O RunddichtringO more, and the advantage of this cushion rubber is: the anti-oil that tool is good, anti-water, the characteristic of anti-solvent and anti-high pressure oil, the tool good compression has certain wear-resistant and extending force, and cost is very low.But the structure of this seal ring is used on the parts of this high motion frequency of ransaxle, and wear resistance that it possessed and sealing effect just seem and be not very desirable.
Seal relevant invention with ransaxle before and use the novel improvement that proposes all to be how to install oil sealing or change sealing part structure, as China Patent No. CN99202390.4, the oil sealing bearing that is provided with that proposes in the model utility " vehicle rear bridge shell axle tube oil seal structure " that proposed on 01 02nd, 1999 better uses oil sealing, but the problem of fundamentally resolving easy leakage of oil all useless.
The model utility content
The utility model has overcome the deficiencies in the prior art, and a kind of novel ransaxle is provided, and solves the unfavorable problem of sealing configuration of present ransaxle.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
A kind of novel ransaxle, the Sealing at this piston place are this special envelope Sealing, and the wheel limit Sealing in the ransaxle is a labyrinth seal, labyrinth seal is provided with steel bushing outward, steel bushing inside is provided with felt, and ransaxle wheel limit is that bolts and nuts connect, and steel bushing is arranged between the screw bolt and nut.
Compared with prior art, the beneficial effects of the utility model are:
1, the direct contact piston surface, lower end of this special envelope Sealing, the to-and-fro motion wearing and tearing are little, has certain supporting role, to overcoming piston off-centre certain effect is arranged, the not direct contact movement surface of the O type circle of upper end, avoided wearing and tearing, played good effect to prolonging seal life, sealing effect is stable.
2, the wheel limit Sealing in the ransaxle is a labyrinth seal, and effective barrier functionality is played in the immersion of muddy water dust; The use of labyrinth seal reduces greatly to the processing request on the surface of the hole axle part that is mated, effectively cuts down finished cost and difficulty.Labyrinth seal is provided with steel bushing outward, and steel bushing inside is provided with felt, can effectively stop the immersion of silt.
3, ransaxle wheel limit is that bolts and nuts connect, and has made things convenient for dismounting and maintenance greatly; The use of the steel bushing that uses between the screw bolt and nut both can be used as packing ring, can prevent effectively that again bolt from rotating, big chamfer design can be used in steel bushing inside, makes the chamfering at this position of semiaxis enough big, thereby avoid occurring on the semiaxis step of little chamfering, semiaxis intensity is strengthened.
Description of drawings
Fig. 1 is the utility model piston place sealed structural representation.
Fig. 2 is the wheel limit structural representation in the utility model ransaxle.
Embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated.
In conjunction with illustrated in figures 1 and 2, a kind of novel ransaxle, it is characterized in that: the Sealing at piston place is this special envelope Sealing 1, wheel limit Sealing in the ransaxle is a labyrinth seal 2, the labyrinth seal 2 outer steel bushings 3 that are provided with, steel bushing 3 inside are provided with felt 4, and ransaxle wheel limit is that bolt 5 is connected with nut 6, between bolt 5 and the nut 6 steel bushing 3 is arranged.
Claims (1)
1. novel ransaxle, it is characterized in that: the Sealing at piston place is this special envelope Sealing (1), wheel limit Sealing in the ransaxle is labyrinth seal (2), the outer steel bushing (3) that is provided with of labyrinth seal (2), steel bushing (3) inside is provided with felt (4), ransaxle wheel limit is that bolt (5) is connected with nut (6), between bolt (5) and the nut (6) steel bushing (3) is arranged.
