Abstract
The utility model relates to an automobile driving axle differential lock assembly, and aim to provide an automobile driving axle differential lock assembly with an improved structure. According to the automobile driving axle differential lock assembly, not only is a mounting hole not required to be formed in one end of a piston rod, but also the number of parts required is low, the structure is simplified, and the cost is reduced. The automobile driving axle differential lock assembly comprises a spring, a shift fork, the piston rod, an O-shaped ring, a bushing, a seal liner, a cylinder cover, a gasket, a pressure switch and a sliding engagement sleeve; one end of the piston rod penetrates through the shift fork, is sleeved with the spring, and extends into a main reducer casing; the outer wall of the sliding engagement sleeve is connected with the shift fork; the O-shaped ring, the bushing, the seal liner, the cylinder cover, the gasket and the pressure switch are connected in sequence at the other end of piston rod; and a bolt penetrates through the seal liner and the cylinder cover and is then connected with the main reducer casing. The automobile driving axle differential lock assembly is characterized by further comprising an adjusting washer, the inner diameter of the adjusting washer is corresponding to the shaft diameter of the piston rod, and the adjusting washer is arranged between the shift fork and the piston rod.
Description
Technical field
The utility model relates to a kind of automobile assembly structure, relates in particular to a kind of automobile drive axle differential lock assembly structure.
Background technique
The medium and heavy truck ransaxle of prior art differential lock adopts following structure, as shown in Figure 1, this structure mainly comprises: spring 1, shift fork 2, piston rod 4, hexagon nut 11, double-screw bolt 12, O type circle 5, switch plunger 15, liner 7, cylinder head 8, packing ring 9, pressure switch 10 and the engagement cover that slides.One end of piston rod 4 passes shift fork 2 back cover upper springs and is deep in the bevel housing, the outer wall that the engagement of sliding is overlapped is connected with shift fork, the other end of piston rod 4 is equipped with hexagon nut 11 and double-screw bolt 12, O type circle 5, lining 6, liner 7, cylinder head 8, packing ring 9 and pressure switch 10 are installed afterwards successively, pass through bolton at last.Owing to slide the engagement cover need and differential casing between keep about 0.5mm the gap, this gap is regulated by rotating double-screw bolt 12, this is regulated needs the part of prepackage more, double-screw bolt and nut are installed are needed in advance an end processing mounting holes at piston rod, not only waste time and energy, and needing part more, cost is higher.
The model utility content
At deficiency of the prior art, the utility model aims to provide a kind of automobile drive axle differential lock assembly of architecture advances, not only need not at piston rod one end processing mounting holes, and required part is less, shortens axial distance, reduces and adjusts difficulty, simplified structure reduces cost.
In order to address the above problem, this kind automobile drive axle differential lock assembly comprises: spring, shift fork, piston rod, O type circle, lining, liner, cylinder head, packing ring, pressure switch and slip engagement cover; One end of piston rod is deep in the bevel housing after passing shift fork and overlapping upper spring, the outer wall that the engagement of sliding is overlapped is connected with shift fork, the other end of piston rod is connected with O type circle, lining, liner, cylinder head, packing ring and pressure switch in turn, bolt is connected with bevel housing after passing liner and cylinder head, this automobile drive axle differential lock assembly is characterised in that: comprise that is also adjusted a packing ring, the internal diameter of this adjustment packing ring is corresponding with the diameter of axle of piston rod and be arranged between shift fork and the piston rod.
Preferably, described adjustment packing ring is that internal diameter is that 15～30mm, thickness are the steel packing ring of 0.1～3mm.
The beneficial effects of the utility model are: this differential lock assembly replaces to the adjustment packing ring with hexagon nut and double-screw bolt, not only reduced part, reduced cost, also need not in addition to offer attachment hole in the piston rod end in advance, reduced cost of labor and improved the bulk strength of this device.
Description of drawings
Fig. 1 is the structural representation of automobile drive axle differential lock assembly of the prior art;
Fig. 2 is the structural representation of automobile drive axle differential lock assembly of the present utility model;
Fig. 3 is the decomposition texture schematic representation of automobile drive axle differential lock assembly of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
In conjunction with Fig. 2 and Fig. 3, this kind automobile drive axle differential lock assembly, it mainly comprises: spring 1, shift fork 2, adjustment packing ring 3, piston rod 4, O type circle 5, lining 6, liner 7, cylinder head 8, packing ring 9, pressure switch 10 and the engagement cover 13 that slides.Be inserted in earlier on one end of piston rod 4 and adjust packing ring 3, be deep in the bevel housing after passing shift fork 2 and overlapping upper spring 1, the hand piston rod is motionless until pressing, the outer wall that meshes cover 13 that slides is connected with shift fork, make and mesh the slit that keeps about 0.5mm between cover and the differential casing, if do not reach requirement, replaceable suitable adjustment packing ring, adjusting packing ring here, can to adopt internal diameter be that 15～30mm, thickness are the steel packing ring of 0.1～3mm.Afterwards, the other end of piston rod 4 is connected with O type circle 5, lining 6, liner 7, cylinder head 8, packing ring 9 and pressure switch 10 in turn, bolt 14 passes liner 7 and is connected with bevel housing with cylinder head 8 backs, and this device is fastened on the bevel housing.
