Below with reference to Fig. 1, describe according to the drive axle 100 for vehicle of the utility model embodiment.
The drive axle 100 for vehicle according to the utility model embodiment, as shown in Figure 1, comprising: housing 1, seal plug 2 and gasket seal 3.
With reference to Fig. 1, on housing 1, there is hydraulic fluid port 11, here, housing 1 can be bevel housing, and housing 1 can be also wheel reduction gear housing, and housing 1 can also be axle housing, and the shape of housing 1 is not done concrete restriction.
With reference to Fig. 1, seal plug 2 is fixed to hydraulic fluid port 11, and seal plug 2 has bar portion 22 and head 21, and the radial dimension of head 21 is greater than the radial dimension of bar portion 22, gasket seal 3 is set in bar portion 22, and the hydraulic fluid port 11 that gasket seal 3 is pressed on housing 1 by head 21 is sentenced sealing hydraulic fluid port 11.
Wherein, the outside dimension D3 of gasket seal 3 is not more than the outside dimension D2 of head 21, that is to say, the outside dimension D3 of gasket seal 3 can equal the outside dimension D2 of head 21, the outside dimension D3 of gasket seal 3 also can be less than the outside dimension D2 of head 21, thereby makes gasket seal 3 there is no exposed parts.Thus, head 21 is after press seal pad 3, and the outward flange of head 21 can not produce impression on gasket seal 3, makes the outward flange of gasket seal 3 in use be always flattened state, and is difficult for producing buckling deformation.
Because gasket seal 3 is difficult for buckling deformation, not easy oil leakage when gasket seal is used for 3 two times.That is to say, drive axle 100 can be pulled down seal plug 2 and gasket seal 3 when using hydraulic fluid port 11, and hydraulic fluid port 11 can be loaded onto seal plug 2 and original gasket seal 3 after finishing using again, and the sealing effectiveness of sealing pad 3 does not subtract.Thus, gasket seal 3 is reusable, and sealing effectiveness is good, oil tight, thereby extends the service life of drive axle 100.In addition aborning, because gasket seal is used not easy oil leakage 3 two times, thereby avoid stopping line problem because hydraulic fluid port 11 leakage of oils cause manufacturing line, and then enhance productivity.
According to the drive axle 100 for vehicle of the utility model embodiment, by the outside dimension D3 of gasket seal 3 being arranged to be not more than the outside dimension D2 of head 21, make gasket seal 3 not be prone to even buckling deformation of impression, thereby extend the service life of gasket seal 3, guarantee the leak tightness of drive axle 100.And gasket seal 3 is reusable, aborning, also can avoids stopping line problem because hydraulic fluid port 11 leakage of oils cause manufacturing line, thereby enhance productivity, and then reduce productive costs and the use cost of drive axle 100.
In embodiment more of the present utility model, as shown in Figure 1, the inner diameter d 3 of gasket seal 3 is greater than the diameter D1 of hydraulic fluid port 11, makes gasket seal 3 there is no interior dew part.Thus, head 21, after press seal pad 3, can not produce impression at hydraulic fluid port 11 places on the inward flange of gasket seal 3, makes the inward flange of gasket seal 3 in use be always flattened state, and is difficult for producing buckling deformation.Thereby further guarantee the sealing effectiveness of gasket seal 3, make gasket seal 3 reusable.
Further, as shown in Figure 1, the outside dimension D3 of gasket seal 3 is less than the outside dimension D2 of head 21, even while making gasket seal 3 slightly biased in installation site, gasket seal 3 is not prone to exposed parts yet.Thus, can further guarantee that the outward flange of head 21 can not produce impression on gasket seal 3, thereby further guarantee the leak tightness of gasket seal 3.
Particularly, as shown in Figure 1, bar portion 22 has external thread structure, and bar portion 22 is threaded io hydraulic fluid port 11, that is to say, the inside face of hydraulic fluid port 11 is flat of thread, the outer peripheral face of bar portion 22 is the flat of thread coordinating with the inner peripheral surface of hydraulic fluid port 11, thereby bar portion 22 and hydraulic fluid port 11 are threaded connection.Thus, easy to connect between seal plug 2 and hydraulic fluid port 11, dismounting easily.
Alternatively, as shown in Figure 1, seal plug 2 is interior hexagonal plug, and seal plug 2 is provided with hexagon blind hole 25, blind hole 25 from the head 21 end face is recessed towards bar portion 22, thereby makes seal plug 2 can use special tool to be arranged on housing 1 as inner-hexagon spanner.
Alternatively, gasket seal 3 is annular arrangement, beyond the flat ring-type that gasket seal 3 is hollow, is enclosed within bar portion 22.Thereby make gasket seal 3 coordinate and the periphery of hydraulic fluid port 11 can be sealed completely with seal plug 2, and gasket seal 3 forms annular arrangement, can make the stressed uniformity of gasket seal 3, be difficult for bending.
Advantageously, seal plug 2 is gyro-rotor, and for example, in the example depicted in fig. 1, head 21 is cylindrical with the outline of bar portion 22.Thus, seal plug 2 processing are very easy to, thereby reduce the tooling cost of seal plug 2.
In specific embodiments more of the present utility model, as shown in Figure 1, head 21 passes through inclined-plane 23 transition with the intersection of bar portion 22, thus, can be convenient to the processing of seal plug 2, and avoid head 21 and excessive the causing of intersection stress of bar portion 22 to damage, and inclined-plane 23 can produce certain positioning action to gasket seal 3.
In the example shown in Fig. 1, in bar portion 22, also there is relief groove 24, the setting of relief groove 24 can be convenient to the flat of thread in machine up bar portion 22.
Alternatively, gasket seal 3 is copper, thus, the shop characteristic of gasket seal 3 is good, easily processing, and the fatigue resistance of gasket seal 3 and toughness good, long service life.
Alternatively, seal plug 3 and housing 1 are steelwork.Thus, the structural strength of seal plug 3 and housing 1 is large, is difficult for destroyed.
In a concrete example of the present utility model, hydraulic fluid port 11 is the oil drain hole of housing 1 or the oil filling port of housing 1.That is to say, the oil drain hole of housing 1 can adopt the seal plug 2 of above-described embodiment and gasket seal 3 to seal, and the oil filling port of housing 1 also can adopt the seal plug 2 of above-described embodiment and gasket seal 3 to seal.Thereby guarantee drive axle 100 at oil drain hole place or the leak tightness at oil filling port place.
According to the vehicle of the utility model embodiment, comprise the drive axle 100 for vehicle according to the utility model above-described embodiment.
According to the vehicle of the utility model embodiment, the gasket seal 3 that seal plug 2 is set and does not expose by the oil drain hole at drive axle 100 or oil filling port place, thus make the gasket seal 3 can Reusability, and drive axle 100 favorable sealing properties.
