Abstract
The utility model discloses a differential mechanism. The differential mechanism includes a shell which is inserted by a planetary gear shaft; a pin hole is arranged on the shell, and a pin can penetrate through the pin hole so that the planetary gear shaft and the shell are connected; and the inner wall of the end port of the pin hole is provided with a transparent clamping hole. The differential mechanism also includes a fixed cap which is insert into the pin hole after the pin is inserted into the pin hole and is used for preventing the pin from falling off; and the fixed cap is provided with an elastic clamping piece which protrudes outwards and extends into the clamping hole. The differential mechanism provided by the utility model adds the extra fixed cap, uses the elastic clamping piece on the fixed cap to connect the fixed cap and the pin hole on the shell, so as to realize the fast installation or disassembly, and at the same time to prevent the pin from falling off caused by the riveting and pressing of the pin being inadequate. The differential mechanism of the utility model is suitable for various vehicles with the differential mechanism, and is convenient in replacement of the internal planetary gear of the differential mechanism.
Description
Technical field
The utility model relates to a kind of auto parts and components, relates in particular to a kind of differential mechanism.
Background technique
In the differential mechanism of automobile, by planet pin, two relative planetary pinions are installed.Planet pin is inserted on the housing of differential mechanism, is provided with pin hole on housing, by pin, planet pin is connected with housing.In existing structure, often by the interference fit of pin and pin hole or pin riveting is out of shape pin is fixed, be difficult to dismounting.In actual production, may there is the problem that pin riveting is not in place, pin is easily thrown out of, cause the damage of differential mechanism.
Summary of the invention
The technical problems to be solved in the utility model, is to provide a kind of differential mechanism, and it can connect reliably to pin, and can be easy to dismounting.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of differential mechanism, comprise the housing that is fitted with planet pin, on housing, be provided with and can penetrate pin so that the pin hole that planet pin is connected with housing, the inwall of the port of described pin hole is provided with penetrating blocked hole, after being also included in insertion pin, fill in the locking cap for stopping that pin is deviate from pin hole, this locking cap is provided with outside ejection and stretches to the resilient clamp member in blocked hole.
As to restriction of the present utility model, one end of locking cap is provided with a central blind hole, and one end of described pin is inserted in central blind hole.
As another kind of the present utility model is limited, described resilient clamp member is the bending of perk on locking cap, and this bending is obliquely installed.
As to further restriction of the present utility model, the perk angle of bending is 17-23 °.
The utility model also has another kind of restriction, and the below of bending is provided with a groove that holds this bending.
Owing to having adopted above-mentioned technological scheme, compared with prior art, obtained technological progress is the utility model:
Differential mechanism provided by the utility model, increase extra locking cap, utilized the resilient clamp member on locking cap to be connected with the pin hole on housing locking cap, can realize installation or removal rapidly, meanwhile, also avoided the pin riveting pin causing not in place to come off; Resilient clamp member adopts bending, its convenient processing and manufacture, compact structure; Groove is set below bending, can facilitates the installation of locking cap, simplify the structure of pin hole.
The utility model is applicable to, in the various automobiles with differential mechanism, facilitate the replacing of differential mechanism internal planetary gear.
The utility model is described in further detail below in conjunction with Figure of description and specific embodiment.

Fig. 1 is the utility model embodiment's overall structure schematic diagram;
Fig. 2 is I portion enlarged view in Fig. 1.
In figure: 1, housing; 2, planet pin; 3, planetary pinion; 4, pin; 5, blocked hole; 6, locking cap; 7, bending; 8, groove; 9, pin hole.
Embodiment
Embodiment
As shown in Figures 1 and 2, the present embodiment discloses a kind of differential mechanism, on its housing 1, is fitted with planet pin 2, and two planetary pinions 3 are relatively installed on planet pin 2.On housing 1, be provided with a pin hole 9, this pin hole 9 is interior can insert pin 4, thereby planet pin 2 and housing 1 are coupled together.
The said structure of this differential mechanism is identical with existing differential mechanism.
The present embodiment is from the different of prior art:
In the differential mechanism of the present embodiment, also on the inwall of the port of pin hole 9, be provided with a penetrating blocked hole 5, after inserting pin 4, can be again to filling in a locking cap 6 in pin hole 9, for stopping pin 4, deviate from.
On locking cap 6, be provided with a resilient clamp member that can outwards eject, can be deep enough to blocked hole 5 after this resilient clamp member ejects, thus locking cap 6 and housing 1 are fixed.
The resilient clamp member that the present embodiment adopts is the bending 7 of perk on locking cap 6.This bending 7 can directly process on locking cap 6, also can be used as additional part and is fixed on locking cap 6.
The below of bending 7 is provided with a groove 8 that holds this bending 7, and when filling in to pin hole 9, bending 7 is depressed, and is temporarily stored in groove 8, and when bending 7 is alignd with blocked hole 5, it can eject automatically, realizes clamping with blocked hole 5.For the ease of manufacturing, bending 7 is inclined on locking cap 6, and its perk angle is 17 °-23 °.
When locking cap 6 is installed, can directly push it against the inside of pin hole 9; And when taking off locking cap 6, need first to press down bending 7, and make it exit blocked hole 5, now pull back locking cap 6, it can be taken off smoothly.Take off after locking cap 6, pin 4 can exit in pin hole 9, now can dismantle planet pin 2 and planetary pinion 3.
Installation location for the ease of pin 4, can be provided with in one end of locking cap 6 central blind hole, and one end of pin 4 is inserted in central blind hole.Like this, pin 4 can insert easily and locate, and under dismounting, during locking cap 6, can leave certain space so that pin 4 can be taken out easily.
