Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment: a kind of stable type vehicle rear-axle housing, as depicted in figs. 1 and 2, including rear axle housing body 1, in rear axle housing body 1
Middle part be equipped with disengaging oilhole 2, disengaging oilhole 2 be equipped with sealing block 11, for operator to the oil liquid in vehicle rear-axle housing into
Row rapidly and thoroughly replacement operation.
In view of in existing production technology, the oil liquid discharge in automobile rear axle housing 1 is not thorough, set in the rear axle housing body 1
There is oil-guide device 3, oil-guide device 3 includes semi circular shells 4 identical with 1 inner wall shape of rear axle housing body and fixes company with semi circular shells 4
The oil pipe 5 connect, oil pipe 5 are threaded through in disengaging oilhole 2, internal cavities of the oil liquid section store under normal condition in semi circular shells 4
In, it is injected and is discharged by oil pipe 5.The inner wall of semi circular shells 4 is equipped with and refuses oil reservoir 15 (as shown in Figure 4), can ensure oil liquid
Can be quick in discharge process, reduce absorption residual, after oil liquid completes sufficiently releasing under its gravity,
Operator can be cleared up manually by the work of oil-guide device 3.
It is equipped with a pair of of sliding block 6 in the side wall of oil pipe 5, the inner wall of disengaging oilhole 2 is equipped with the sliding slot 7 slid for sliding block 6, disengaging
The one end of oilhole 2 inside rear axle housing body 1 is equipped with annular groove 8, while being equipped with locking in the other end of disengaging 2 internal chute 7 of oilhole
Slot 9.Under normally locking closed state, 6 inlay card of sliding block goes back spiral shell on the oil inlet outside side wall of oil pipe 5 in locking slot 9
Line is connected with latch segment 10, locking can be fixed to the position of semi circular shells 4 by the locking extruding of latch segment 10.It is passing in and out
Oilhole is additionally provided with sealing ring 14 on 2 aperture, facilitates the stabilization locking effect for ensureing latch segment 10, improves sealing performance.
When operator needs to carry out the cleaning of 4 inner wall of semi circular shells adherency oil liquid, latch segment 10 is unscrewed, so that sliding block 6
It can produce out of locking slot 9,7 carry out along the chute along 5 radial slippage of oil pipe, so that the sliding block 6 on oil pipe 5 slides into annular groove 8
Point, so as to realize circumferential rotation, the effect by rotating centrifugal force will be adsorbed on the oil liquid of 4 inner wall of semi circular shells from its table
Emaciated face is from finally by the discharge of 5 part of oil pipe.Since sliding repeatedly may bring the abrasion of 6 part of sliding block, in the side of sliding block 6
Wall is equipped with wear-resistant block 18 (as shown in Figure 3), can enhance the wear-resisting property between sliding block 6 and sliding slot 7 etc., and reducing abrasion may
The excessive fit clearance of bring is additionally provided with oblique angle 19 (as shown in Figure 3) at the both ends of sliding block 6, facilitates assist operators and exist
It is smoothly transferred to annular groove 8 and 9 part of locking slot in slipping, realizes effective guide effect, so that rotational slip acts
It is more convenient reliable.
As depicted in figs. 1 and 2, it is contemplated that opposite rotation may occur between semi circular shells 4 for rear axle housing body 1, cause
Oily 3 part of device it is unstable.It is equipped with oil guide groove 12 in the inner wall of rear axle housing body 1, the outer wall of semi circular shells 4 is equipped with and oil guide groove 12
Mating guide block 13, the process that can be locked in latch segment 10 by the cooperation between oil guide groove 12 and guide block 13
In, it ensures sufficient locking effect, reduces the relative rotation being likely to occur.It can be assisted between oil guide groove 12 and guide block 13 simultaneously
Oil liquid rapid accumulation between semi circular shells 4 and rear axle housing body 1 is penetrated into, and is flowed down along slot to quick.
Platform block 16 is equipped on the end wall of rear axle housing body 1 simultaneously, the side wall of semi circular shells 4 is embedding equipped with contradicting with platform block 16
Block 17 is cooperated by the conflict of platform block 16 and abaculus 17, helps further to ensure supporting between semi circular shells 4 and rear axle housing body 1
Touch closed and abundant degree, it helps reduce the situation that oil liquid penetrates into gap, ensure the stabilization lubricating and wear-resisting under working normally
Effect.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
