Description
Technical field
The utility model belongs to driving bridge for engineering machinery field, specifically, particularly relates to a kind of loader-digger hydraulic differential and locks.
Background technique
At present, the differential lock that loader-digger ransaxle uses generally adopts pin-type load differential lock and castellated differential lock, its role is to when tyre slip, and that improves loader passes through performance.For the loader that rotating speed is lower, especially castellated differential lock, the sensitivity of locking and differential is lower, and when radius of turn is larger, differential mechanism is still in locking state, reduces the working life of gear and spline.Also occurred hydraulic type differential lock in recent years, but its oil circuit is positioned on differential casing, requires higher to processing and casting.Therefore, design a kind of structure simple, convenient processing and manufacture, the hydraulic differential lock that locking and differential function can control flexibly becomes the active demand of engineering machinery field.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defect, provides a kind of compact structure, cost of production low, easy to maintenance, can according to actual conditions, and the loader-digger hydraulic differential controlling ransaxle differential and locking function is flexibly locked.
Described loader-digger hydraulic differential is locked, comprise housing and piston cap, be provided with the piston ring and piston rod that cooperatively interact in piston cap, shift fork is socketed on piston rod, internal tooth casing and external tooth cover are connected with differential carrier and semiaxis respectively, and shift fork is fixed in the groove of external tooth cover.
Internal tooth casing is connected with differential carrier and semiaxis preferably by spline respectively with external tooth cover.
The end of differential carrier is provided with groove, and internal tooth casing is fixed respectively by baffle ring, back-up ring and rolling bearing in the two ends of differential carrier.
Housing and piston cap are located on bracket.
Compared with prior art, the beneficial effects of the utility model are:
1, internal tooth casing and external tooth cover are connected with differential carrier and semiaxis respectively, effectively make use of the inner space of axle housing, make main transmission structure compacter;
2, the utility model cost of production is low, realize locking and differential by controlling the connection of semiaxis and differential carrier and disconnection, because internal tooth casing is fixing on the differential housing, external tooth cover is stuck on shift fork, even if take out semiaxis, external tooth cover also can not drop to inside axle housing, and more for convenience, reliability is high for maintenance and assembling; The internal spline again only needing semiaxis to aim at external tooth cover during assembling can complete assembling.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, loader-digger hydraulic differential lock comprises housing 1 and piston cap 4, housing 1 and piston cap 4 are located on bracket 8, the piston ring 5 and piston rod 3 that cooperatively interact is provided with in piston cap 4, shift fork 2 is socketed on piston rod 3, internal tooth casing 12 is connected with differential carrier 13 and semiaxis 9 respectively by spline with external tooth cover 11, shift fork 2 is fixed in the groove of external tooth cover 11, the end of described differential carrier 13 is provided with groove, and internal tooth casing 12 is fixed respectively by baffle ring 17, back-up ring 16 and rolling bearing 14 in the two ends of differential carrier 13.
The utility model when mounted, is installed in the main driving assembly 19 of ransaxle 18, and one end of shift fork 2 is connected with piston rod 3 by pin 7, and the other end of shift fork 2 is fixed on by annular spring 10 in the groove of external tooth cover 11; Sensor installation in piston cap 4, makes operator can judge that whether differential lock function is normal according to signal, more hommization.
Working principle of the present utility model is: hydraulic oil enters between piston cap 4 and piston ring 5 by (returning) mouth that enters in piston cap 4, the confined space formed by rectangular seal produces certain pressure, make piston ring 5 promote piston rod 3 vertically, piston rod 3 drives external tooth cover 11 to produce axial motion along the supermedial spline of semiaxis 9 by shift fork 2.When external tooth cover 11 and internal tooth casing 12 engage, semiaxis 9 is as a whole with differential carrier 13 one-tenth, and semiaxis 9 is identical with differential gear 15 rotating speed, thus make there is no differential between the semiaxis of both sides, the moment of torsion of motor transmission is evenly distributed on two semiaxis, effectively improve loader-digger in wet-skid road surface wheel-slip, lose the defect of tractive force; When hydraulic oil fuel cut-off, under the effect of spring 6, promote piston ring 5 reset, and then drive external tooth cover 11 to be separated with internal tooth casing 12, locking function is lost, recovers differential function.
