Abstract
The utility model relates to a differential cross axle. The differential cross axle comprises a middle connection body. A through hole is formed in the center of the middle connection body, four planet gear shafts are uniformly distributed on the side wall of the middle connection body, and a locating hole is formed in the other end, opposite to one end connected with the middle connection body, of each planet gear shaft. The differential cross axle is characterized in that the outer surfaces of the planet gear shafts are coated with wear-resistant layers. By adopting the technical scheme, the outer surfaces of the planet gear shafts are coated with the wear-resistant layers, and therefore the stable performance of a differential is guaranteed.
Description
Technical field
The utility model relates to a kind of differential spider.
Background technique
Differential mechanism is the main part of ransaxle, when car is turned, the radius of turn of two wheels is different, need a wheel to hurry up, one a little slower, realize the two-wheeled different rotating speeds, must realize by differential mechanism, a cross axle is arranged in differential mechanism, cross axle has generally comprised the middle part union body, union body central position, middle part is provided with through hole, be evenly distributed with four planet pins on the union body sidewall of middle part, four planet pins and middle part union body are welded and fixed, described four planet pins are respectively used to install planetary pinion, planet pin is provided with positioning hole with respect to it with the other end that the middle part union body is connected an end.
But, the differential spider of this structure, when planet pin is used, its surface abrasion is large, and long-time the use, make the performance of differential mechanism be affected.
Summary of the invention
The purpose of this utility model: in order to overcome the defect of prior art, the utility model provides a kind of differential spider, and it is by the wearing layer be coated with on the planet pin outer surface, thereby can guarantee the differential mechanism stable performance.
The technical solution of the utility model: a kind of differential spider, include the middle part union body, union body central position, middle part is provided with through hole, be evenly distributed with four planet pins on the union body sidewall of middle part, planet pin is provided with positioning hole with respect to it with the other end that the middle part union body is connected an end, it is characterized in that: on the outer surface of described planet pin, be coated with wearing layer.
Adopt technique scheme, by the wearing layer be coated with, thereby can guarantee the differential mechanism stable performance on the planet pin outer surface.
Further setting of the present utility model: described wearing layer adopts titanium carbide.
Adopt above-mentioned further setting, titanium carbide is typical transition metal carbide, and its crystalline structure has determined that it has good wear-resisting property.
Further setting more of the present utility model: described middle part union body and planet pin are wholely set, and are provided with circular-arc junction surface between described middle part union body and planet pin.
Adopt above-mentioned further setting again, middle part union body and planet pin are wholely set, and make processing convenient; The circular-arc junction surface arranged, can reduce the stress between middle part union body and planet pin, prevents this place's fracture.
Further setting of the present utility model: described planet pin is provided with groove with respect to it with the other end that the middle part union body is connected an end.
Adopt above-mentionedly further to arrange, the groove of setting, in the time of can preventing from installing, the planet pin installation personnel of damaging, safer.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model specific embodiment;
The sectional view that Fig. 2 is the utility model specific embodiment.
Embodiment
As shown in Figure 1, 2, a kind of differential spider, include middle part union body 1, union body 1 central position, middle part is provided with through hole 11, be evenly distributed with four planet pins 2 on union body 1 sidewall of middle part, planet pin 2 is connected an end with middle part union body 1 the other end with respect to it is provided with positioning hole 21, is coated with wearing layer 3 on the outer surface of described planet pin 2.Described wearing layer 3 adopts titanium carbide.Titanium carbide is typical transition metal carbide, and its crystalline structure has determined that it has good wear-resisting property, therefore, by the wearing layer 3 be coated with, thereby can guarantee the differential mechanism stable performance on planet pin 2 outer surfaces.
Described middle part union body 1 is wholely set with planet pin 2, is provided with circular-arc junction surface 4 between described middle part union body 1 and planet pin 2.In the utility model specific embodiment, described middle part union body 1 is integrated with planet pin 2 cold forgings.
In the utility model specific embodiment, described planet pin 2 is connected an end with middle part union body 1 the other end with respect to it is provided with groove 22, the groove 22 of setting, and in the time of can preventing from installing, planet pin 2 installation personnel of damaging, safer.
Claims (2)
1. a differential spider, include the middle part union body, union body central position, middle part is provided with through hole, be evenly distributed with four planet pins on the union body sidewall of middle part, planet pin is provided with positioning hole with respect to it with the other end that the middle part union body is connected an end, be coated with the wearing layer that titanium carbide is made on the outer surface of described planet pin, it is characterized in that: described middle part union body and planet pin are wholely set, and are provided with circular-arc junction surface between described middle part union body and planet pin.
