Abstract
The utility model provides a fixing structure of a differential planet gear shaft, belonging to the technical field of automobile differential. The problem that a positioning pin is easy to cut and disconnect when a differential is in circular motion in the prior art is solved. In the fixing structure of the differential planet gear shaft, the differential comprises a shell and a planet gear shaft, wherein through holes for installing the planet gear shaft are arranged at the two symmetrical sides of the shell, and the outer side of the shell body, on which the through holes are arranged, is connected with retaining strips which are covered on the through holes for blocking the planet gear shaft. In the utility model, as a positioning pin fixing structure in the prior art is omitted, the intensity of the planet gear shaft is increased, and the structure is simplified.
Description
Technical field
The utility model belongs to the automobile differential technical field, relates to a kind of fixed structure of differential spider pinion shaft.
Background technique
At present, be fixed with circular cone driven tooth wheel disc on the differential casing, penetration hole is offered in the both sides of symmetry on housing, and planet pin is installed in penetration hole, be provided with the positioning hole of vertical penetration hole at a side penetration hole place, the installing and locating pin is fixed planet pin one end in positioning hole.When the differential mechanism of this structure is made circular movement, planetary pinion is because of being subjected to the influence of centrifugal force, the locating stud that is attached thereto then is subjected to the influence of shearing force, make locating stud be sheared disconnection easily, thereby deviate from differential casing, and the locating stud of deviating from can break gear even can be stuck in gear and cause the situation of difficult of turning.
Summary of the invention
There is above-mentioned problem in fixed structure at existing differential spider pinion shaft of the present utility model, a kind of fixed structure of differential spider pinion shaft is provided, this fixed structure can be fixed on the star gear shaft in the differential casing, and when fracture takes place planet pin, can not deviate from differential casing, have advantage simple in structure, that processing is easy to assembly.
The utility model is realized by following technical proposal: a kind of fixed structure of differential spider pinion shaft, differential mechanism comprises housing and planet pin, on the both sides of housing symmetry, offer the penetration hole that planet pin is installed, it is characterized in that, all be connected with on the hull outside at described penetration hole place and be covered in the catch that is used to stop planet pin on the penetration hole.
The utility model is by being provided with catch on housing, and catch covers on the penetration hole outside, like this, is sheared at planet pin and has no progeny because stopping of catch and can not deviate from housing prevents that the planet pin of deviating from from breaking gear.
In the fixed structure of above-mentioned differential spider pinion shaft, the chunk that adds with shell body wall thickening is set between described catch and the hull outside, the end of above-mentioned planet pin is passed and is added chunk and withstand on the catch.By adding chunk the hole depth of penetration hole is strengthened, like this when fracture takes place planet pin, because planet pin one end of fracture is positioned at the bigger hole of hole depth, planet pin can be not immediately be deviate from outwards.
In the fixed structure of above-mentioned differential spider pinion shaft, the end of described planet pin is provided with collar, and this collar is at catch and add between the chunk.By collar the planet pin of disconnection can not inwardly be deviate from, because catch and collar, the planet pin of disconnection also can work on.
In the fixed structure of above-mentioned differential spider pinion shaft, described catch and add chunk by being bolted on the housing.
Compared with prior art, the fixed structure of this differential spider pinion shaft is by being provided with catch on housing, makes to be sheared at planet pin to have no progeny because stopping of catch and can not deviate from housing prevents that the planet pin of deviating from from breaking gear; And the chunk that adds with shell body wall thickening is set between catch and hull outside, and by adding chunk the hole depth of penetration hole is strengthened, prevent that the star gear shaft that disconnects from deviating from can be not outwards.The utility model increases the intensity of planet pin owing to saved locating stud fixed structure of the prior art, and structure obtains simplifying, and has only set up catch and added chunk, and it is low, reasonable in design to improve cost.
Description of drawings
Fig. 1 is the schematic representation of the fixed structure of this differential spider pinion shaft.
Among the figure, 1, housing; 2, planet pin; 3, penetration hole; 4, catch; 5, add chunk; 6, collar; 7, bolt.
Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1 be the fixed structure of differential spider pinion shaft, differential mechanism comprises housing 1 and planet pin 2, on the both sides of housing 1 symmetry, offer the penetration hole 3 that planet pin 2 is installed, planet pin 2 is installed in penetration hole 3, all is consolidated with the catch 4 that is covered on the penetration hole 3 on housing 1 outside at penetration hole 3 places.Between the catch 4 and housing 1 outside, be provided with housing 1 wall thickening added chunk 5, the end of planet pin 2 is passed and is added chunk 5 and withstand on the catch 4, the end of planet pin 2 is provided with collar 6, and this collar 6 is at catch 4 and add between the chunk 5 catch 4 and add chunk 5 and be fixed on the housing 1 by bolt 7.
By catch 4 is set on housing 1, makes to be sheared and have no progeny because stopping of catch 4 and can not deviate from housing 1 prevents that the planet pin of deviating from 2 from breaking gear at planet pin 2; And the hole depth of penetration hole 3 is strengthened by adding chunk 5, and the end of planet pin 2 is provided with collar 6, prevents that the star gear shaft 2 that disconnects from deviating from can be not outwards.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
