Description
Technical field
The utility model relates to a kind of auto parts and components, especially a kind of automobile drive axle differential mechanism.
Background technique
Automobile differential is to be used for distribution of torque between two output shafts, and guarantees that two output shafts might rotate with different angular velocity.Differential mechanism can solve the difference in rotation that left and right wheels produces well in negotiation of bends.Have only when automobile turning or left and right when taking turns the distance of travelling different, or single wheel skids and when trackslipping, differential gear just can have the relative movement of engagement driving.Existing automobile differential is divided into umbrella tooth differential mechanism, wandering star tooth differential mechanism, and what the master gear of umbrella tooth differential mechanism used is bevel type gear, and shock-resistant ability is strong, shortcoming is when rugged travels down, if the wheel-slip of a side, opposite side wheel are not easy with strength, driving force is undesirable; Wandering star tooth differential mechanism is common on the go-anywhere vehicle, wandering star tooth differential mechanism and umbrella tooth differential mechanism are similar, only gear has changed the wandering star tooth into, the transmission accuracy of this differential mechanism is very high, driving force is big, but exist driving force little equally, if the wheel-slip of a side in motion, the opposite side wheel is not easy problem with strength.
Summary of the invention
The purpose of the utility model pin has provided a kind of automobile drive axle differential mechanism, can strengthen the driving force of ransaxle.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: the automobile drive axle differential mechanism, comprise differential casing, the housing two ends are provided with opening, opening is separately installed with and compresses end cap, it is characterized in that: star tooth supporting axle in the middle of being provided with in the described housing, middle star tooth supporting axle is prismatic, the middle part of middle star tooth supporting axle is provided with center hole, be provided with slot on each surface of middle star tooth supporting axle, star tooth in the middle of being equipped with in the slot, the both sides of middle star tooth are equipped with the semiaxis dental star tooth of vertical interlaced engagement, between the relative semiaxis dental star tooth semiaxis tooth is installed, semiaxis dental star tooth and semiaxis tooth are that vertical interlaced is placed, the both sides of star tooth supporting axle in the middle of the semiaxis tooth is distributed in, and an end of semiaxis tooth contacts with middle star tooth supporting axle, the other end is fixed in the axis hole that compresses end cap, described semiaxis dental star tooth, the semiaxis tooth, the rotation direction of middle star tooth is identical.
To further improvement in the technical proposal: star tooth supporting axle is " ten " shape in the middle of described, the transverse axis of middle star tooth supporting axle and the two ends of vertical pivot are respectively equipped with slot, middle star tooth is installed in the slot, is provided with block in the center hole at middle star tooth supporting axle middle part.
To further improvement in the technical proposal: star tooth supporting axle is a pentagonal prism in the middle of described, is provided with slot on each surface of middle star tooth supporting axle, and middle star tooth is installed in the slot.
Beneficial effect:
Using automobile drive axle differential mechanism described in the utility model, is to have utilized turbine, the Worm type kind of drive, has increased spiral angle, has reduced reverse retaining, and the two-way transmission that has increased differential mechanism is interactive; Owing to be to utilize the star tooth to carry out transmission, make wheel of ransaxle land thrust is also arranged, two-wheeled also can differential during turning, can need the place that tractive force is big, road conditions are relatively poor to travel, be applicable to often travel vehicle on relatively poor road of go-anywhere vehicle, engineering truck, wheel dozer or loader, wheeled tractor etc., have the strong advantage of passing ability.
The middle star tooth supporting axle of described differential mechanism is " ten " shape, and the differential mechanism of this structure is applicable to dilly; The middle star tooth supporting axle of described differential mechanism is a pentagonal prism, and the large and small type vehicle of this structure all can be general.

Embodiment
As Fig. 1, Fig. 2, the embodiment one of the utility model automobile drive axle differential mechanism shown in Figure 3, comprise housing 1, housing 1 two ends are provided with opening, opening is separately installed with and compresses end cap 2,3, star tooth supporting axle 4 in the middle of being provided with in the described housing 1, star tooth supporting axle 4 is " ten " shape in the middle of described, the transverse axis of middle star tooth supporting axle 4 and the two ends of vertical pivot are respectively equipped with slot, star tooth 5 in the middle of being equipped with in the slot, the both sides of middle star tooth 5 are equipped with the semiaxis dental star tooth 6 of vertical interlaced engagement, between the relative semiaxis dental star tooth 6 semiaxis tooth 7 is installed, semiaxis dental star tooth 6 is that vertical interlaced is placed with semiaxis tooth 7, the both sides of star tooth supporting axle 4 in the middle of semiaxis tooth 7 is distributed in, one end of semiaxis tooth 7 contacts with middle star tooth supporting axle 4, the other end is installed in the axis hole that compresses end cap 2 or 3, described semiaxis dental star tooth 6, semiaxis tooth 7, the rotation direction of middle star tooth 5 is identical, is provided with block 8 in the center hole at middle star tooth supporting axle 4 middle parts.
As Fig. 4, Fig. 5, the embodiment two of the utility model automobile drive axle differential mechanism shown in Figure 6, comprise differential casing 1, housing 1 two ends are provided with opening, opening is separately installed with and compresses end cap 2,3, star tooth supporting axle 4 in the middle of being provided with in the described housing 1, middle star tooth supporting axle 4 is a pentagonal prism, be provided with slot on each surface of middle star tooth supporting axle 4, star tooth 5 in the middle of being equipped with in the slot, the both sides of middle star tooth 5 are equipped with the semiaxis dental star tooth 6 of vertical interlaced engagement, between the relative semiaxis dental star tooth 6 semiaxis tooth 7 is installed, semiaxis dental star tooth 6 is that vertical interlaced is placed with semiaxis tooth 7, the both sides of star tooth supporting axle 4 in the middle of semiaxis tooth 7 is distributed in, one end of semiaxis tooth 7 contacts with middle star tooth supporting axle 4, the other end is installed in the axis hole that compresses end cap 2 or 3, described semiaxis dental star tooth 6, semiaxis tooth 7, the rotation direction of middle star tooth 5 is identical, is provided with block 8 in the center hole at middle star tooth supporting axle 4 middle parts.
