Description
Technical Field
The utility model relates to a universal joint technical field specifically says a take rzeppa universal joint of differential lock.
Background
The universal joint is the important part in the vehicle system, undertakes the important task of transmission, and present rzeppa universal joint does not have differential lock structure itself, for example the high-efficient big pivot angle constant velocity drive shaft assembly technical scheme of a novel variation that publication number CN202560865U discloses, and it includes transmission shaft (1), and the one end of transmission shaft (1) links to each other its characterized in that with first rzeppa universal joint (2): the other end of the transmission shaft (1) is connected with a second ball-cage universal joint (3), the second ball-cage universal joint (3) comprises a bell-shaped shell (31), an outer spline (311) connected with a differential is arranged on the bell-shaped shell (31), and a groove (5) matched with a clamping steel wire (4) for a shaft is arranged at the end part of the outer spline (311). According to the technical scheme, the outer spline (311) connected with the differential is arranged on the outer shell (31), so that the function of the differential lock cannot be realized by the conventional ball-cage universal joint.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that, overcome prior art's defect, provide a ball cage universal joint of taking differential lock, come to realize the differential lock function to a certain extent through a simple improvement.
Compared with the prior art, the utility model provides a take ball cage universal joint of differential lock, including the body, the body includes along bell-shaped shell and the transmission shaft that the axial set up according to the preface, and the left end of bell-shaped shell is the opening setting, and bell-shaped shell circumference evenly is equipped with the differential tooth, and each differential tooth constitutes the ring gear.
As an improvement, differential teeth are uniformly arranged on the right end of the outer shell in the circumferential direction, and the diameter of the gear ring formed by the differential teeth is smaller than that of the right end of the outer shell.
As an improvement, the right end of the bell-shaped shell is provided with an annular step, each annular step is provided with each differential gear, and the right end of each differential gear exceeds the annular step towards the right side.
As an improvement, a tooth groove is arranged between adjacent differential teeth, the tooth groove is in an inverted trapezoid shape from the right end view of the bell-shaped shell, the narrow end of the inverted trapezoid is positioned on the inner side, and the wide end of the inverted trapezoid is positioned on the outer side.
As an improvement, the tooth groove comprises a radial end surface, an axial wall surface and two side surfaces of adjacent differential teeth, and the radial end surface is obliquely arranged towards one side of the left end of the outer shell.
After adopting above-mentioned structure, compare with prior art, the utility model has the advantages of it is following: the utility model discloses a bell shell circumference evenly is equipped with the differential tooth, and each differential tooth constitutes the ring gear, consequently increases the differential lock function on the rzeppa universal joint, realizes the differential lock function to a certain extent through a simple improvement, reduces automobile parts quantity, alleviates automobile weight.

Detailed Description
The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The underlying principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the invention.
The following is a more detailed description of the present invention:
fig. 1 is a schematic perspective view of a rzeppa universal joint with a differential lock, which includes a body, the body includes an outer shell and a transmission shaft, the outer shell and the transmission shaft are sequentially arranged along an axial direction, and a left end of the outer shell is provided with an opening.
The utility model discloses improve ball cage universal joint to having the differential lock function to a certain extent, bell housing circumference evenly is equipped with differential tooth 1 promptly, and each differential tooth 1 constitutes the ring gear.
In this example, the right end 3 of the bell housing is uniformly provided with differential teeth 1 in the circumferential direction, and the diameter of the gear ring formed by each differential tooth 1 is smaller than that of the right end 3 of the bell housing. The aforesaid improve and also can say that locate the big terminal surface of rzeppa universal joint with the position of differential tooth 1 to keep away from the left end of the bell-shaped shell that the opening set up, design the back like this, be convenient for process, and ensure that other performances of rzeppa universal joint are not influenced.
As shown in fig. 1, the right end 3 of the bell housing is annular stepped, the annular stepped being provided with each differential tooth 1, the right end of each differential tooth 1 exceeding the annular stepped to the right. The function of the differential lock is realized, the differential gear 1 is strengthened, and the strength and the transmission capacity of the differential gear 1 are ensured.
As shown in fig. 2, a tooth space 2 is formed between adjacent differential teeth 1, and the tooth space 2 is shaped like an inverted trapezoid when viewed from the right end 3 of the bell-shaped housing, with the narrow end of the inverted trapezoid located on the inner side and the wide end of the inverted trapezoid located on the outer side. After the design, the teeth are convenient to engage, so that the function of a differential lock is achieved, and the starting capability and the bad road passing capability of the vehicle on a low-adhesion road surface are improved.
As shown in fig. 3, the tooth groove 2 includes a radial end surface 4, an axial wall surface 5, and two side surfaces of adjacent differential teeth 1, and the radial end surface 4 is disposed obliquely toward the left end side of the outer race. The design is favorable for realizing better combination/separation of the differential gear 1, thereby being favorable for realizing the function of the differential lock.
In understanding the present invention, if necessary, the above structure can be understood together with other drawings, and detailed description is omitted here.
The above description is only an illustrative embodiment of the present invention, and therefore all equivalent changes or modifications made by the structure, features and principles of the present invention are included in the protection scope of the present invention.
