Abstract
The utility model discloses a novel built-in differential lock, which comprises a cylinder outer end cover, a bush, an O-shaped sealing ring, a piston shaft, a return spring, a shifting fork, a reducer shell and an engaging sleeve, wherein the cylinder outer end cover and a gasket are fixedly arranged on the reducer shell; the O-shaped sealing ring is arranged on the piston shaft; the piston shaft is arranged in a cylinder hole of the reducer shell and is connected with the shifting fork; a fork opening end of the shifting fork is connected with the engaging sleeve; the engaging sleeve is sleeved at the tail end of the piston shaft; and the return spring is positioned in the cylinder hole on the reducer shell and is sleeved on the top of the piston shaft. The types of assembly parts are reduced, the assembly structure is simple and compact, and assembling processes are simplified; and moreover, the structure of the differential lock is optimized, most of the structure is arranged in the reducer shell, and the differential lock occupies a small space and is hardly collided.
Description
Technical field
The utility model relates to a kind of differential lock, especially relates to the employed built-in differential lock of main reducing gear on a kind of automobile, belongs to automotive field.
Background technique
Ransaxle is one of important big assembly on the automobile, and the effect of differential lock is when a driving wheel skids, and differential carrier and semiaxis locking are integral, and makes the moment of left and right wheels identical.Because the torsional interaction such as grade of differential mechanism has improved the situation that vehicle gets into a difficult position because any one wheel loses adhesion.It is thus clear that the function of differential lock and rigidity directly have influence on the Security of passing through performance and going of vehicle.At present, the differential lock that is adopted is an external structure, and it is big not only to take up space, and assembling component kind is more, and assembly process is comparatively complicated, and in assembling and vehicle driving process, might be collided with.
The model utility content
Deficiency to the existing technology existence; The utility model technical problem to be solved is; A kind of novel built-in differential lock is provided, has solved problems such as present part main reducing gear component assembly process is complicated, rigidity is not enough, it is big to take up space, be prone to collided with outward, reduced manufacture cost.
For solving the problems of the technologies described above, the technological scheme that the utility model is taked is, a kind of novel built-in differential lock, and it comprises cylinder outer end cap, lining, O RunddichtringO, piston shaft, return spring, shift fork, retarder shell and engagement cover; Be fixed with cylinder outer end cap and gasket on the said retarder shell; Said piston shaft is provided with the O RunddichtringO, and piston shaft is installed in the cylinder-bore of retarder shell; Said piston shaft is connected with shift fork, and the intersection end of shift fork is connected with the engagement cover; Said engagement cover is enclosed within the tail end of piston shaft; Said return spring is positioned at the cylinder-bore on the retarder shell, is placed in the top of piston shaft.
Optimize, above-mentioned novel built-in differential lock, its cylinder outer end cap is provided with pressure switch.
Through improvement, the utlity model has following advantage and good effect to original structure:
1. reduced the kind of Assembly part, the assembly structure compact is simplified assembly process;
2. optimized the differential lock structure, most of structure has been installed on subtracts in the shell, the little and difficult quilt that takes up space collides with.
Description of drawings
Below in conjunction with accompanying drawing and embodiment to the utility model further explain;
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1, the utility model is a kind of novel built-in differential lock, and it comprises cylinder outer end cap 1, lining 2, O RunddichtringO 3, piston shaft 4, return spring 5, shift fork 6, retarder shell 9 and engagement cover 7; Be fixed with cylinder outer end cap 1 and gasket 8 on the said retarder shell 9; Said piston shaft 4 is provided with O RunddichtringO 3, and piston shaft 4 is installed in the cylinder-bore of outer 9 shells of retarder; Said piston shaft 4 is connected with shift fork 6, and the intersection end of shift fork 6 is connected with engagement cover 7; Said engagement cover 7 is enclosed within the tail end of piston shaft 4; Said return spring 5 is positioned at the cylinder-bore on the retarder shell 9, is placed in the top of piston shaft 4.Cylinder outer end cap 1 is provided with pressure switch 11.Engagement is sleeved on the middle part spline of semiaxis.Directly driving shift fork by piston shaft during work makes the engagement cover be connected with the difference shell.The utility model sealing combination device has carried out architecture advances to present main reducing gear differential lock; With simple in structure; Anti-colliding with; Reliability is high, is easier to the design starting point of the assembling and the maintenance of main gearbox assembly, has confirmed last design proposal through the means of calculation of finite element strength and actual tests checking.
Traditional main reducing gear differential lock is made up of cylinder block, pressure switch, piston, O shape circle, declutch shift shaft, shift fork return spring, shift fork, fluting flush end Cock screw, hexagon nut.Being characterized in that declutch shift shaft, shift fork return spring install to subtracts in the shell, and cylinder assembly is assembled on the retarder shell.Promote Cock screw by piston and promote declutch shift shaft, drive shift fork again and carry out work.This differential lock component kind is more, and assembling is complicated, takes up space big and be prone to be collided with.
Referring to Fig. 1, traditional differential lock assembling component kind is more, and assembly process is complicated, and it is big to take up space, and is prone to collided with, and the reliable operation performance is low.
Referring to Fig. 1, the utility model is simplified design of part, has simplified assembly process, makes the differential lock structure very compact, reduces arrangement space, and prevents to collide with, and improves the reliable operation performance, has stronger use value.
Certainly, above-mentioned explanation is not to be the restriction to the utility model, and the utility model also is not limited to above-mentioned giving an example; Those skilled in the art; In the essential scope of the utility model, the variation of making, remodeling, interpolation or replacement all should belong to the protection domain of the utility model.
Claims (2)
1. a novel built-in differential lock is characterized in that: comprise cylinder outer end cap, lining, O RunddichtringO, piston shaft, return spring, shift fork, retarder shell and engagement cover; Be fixed with cylinder outer end cap and gasket on the said retarder shell; Said piston shaft is provided with the O RunddichtringO, and piston shaft is installed in the cylinder-bore of retarder shell; Said piston shaft is connected with shift fork, and the intersection end of shift fork is connected with the engagement cover; Said engagement cover is enclosed within the tail end of piston shaft; Said return spring is positioned at the cylinder-bore on the retarder shell, is placed in the top of piston shaft.
