Description

Novel cross axle universal joint

Technical Field

The utility model relates to the technical field of universal joints, in particular to a novel cross shaft universal joint.

Background

The universal joint is a joint part of a universal transmission device of an automobile driving system, the universal joint is combined with a transmission shaft and is called a universal joint transmission device, the universal joint transmission device is arranged between an output shaft of a transmission and an input shaft of a main speed reducer of a drive axle on a vehicle driven by a front engine and a rear wheel, the transmission shaft is omitted from the vehicle driven by the front engine and the universal joint is arranged between a front axle half shaft which is in charge of driving and steering and wheels.

When the existing cross axle universal joint is used, the rotating angle of the cross axle universal joint is suddenly increased, so that a bearing sleeve is cracked, the bearing is failed, the safe operation of the cross axle universal joint is easily influenced, and the use safety of the cross axle universal joint in a wild environment is reduced.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a novel universal joint pin, which has the advantage of good safety and solves the problems that the rotation angle of the universal joint pin is suddenly increased to crack a bearing sleeve in the use process of the conventional universal joint pin, so that a bearing fails, the safe operation of the universal joint pin is easily influenced, and the use safety of the universal joint pin in a field environment is reduced.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a novel cross axle universal joint, includes cross axle universal joint main part, cross axle universal joint main part includes festival fork one, the spacing protection device of one relative one side fixedly connected with of festival fork, the relative one side of spacing protection device is provided with festival fork two.

Preferably, the mounting plate is fixedly connected to the opposite side of the universal joint spider main body.

Preferably, bearings are arranged on the front side and the rear side of the second joint fork.

Compared with the prior art, the utility model has the following beneficial effects:

the utility model solves the problems that the bearing sleeve is cracked due to the sudden increase of the rotation angle of the universal joint in the use process of the existing universal joint, the bearing is invalid, the safe operation of the universal joint is easily influenced, and the use safety of the universal joint in the field environment is reduced.

In the figure: 1 a cross axle universal joint main body, 2 a fork I, 3 a fork II and 4 a limit protection device.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front", "rear", "both ends", "one end", "the other end", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "provided", "connected", and the like are to be construed broadly, such as "connected", which may be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The universal joint main body 1, the first yoke 2, the second yoke 3, the limiting protection device 4 and the like are all universal standard parts or parts known by those skilled in the art, and the structure and principle of the universal joint main body can be known by those skilled in the art through technical manuals or conventional experimental methods.

Referring to fig. 1-2, a novel universal joint comprises a universal joint body 1, wherein the universal joint body 1 comprises a first joint yoke 2, one side of the first joint yoke 2 opposite to the first joint yoke is fixedly connected with a limiting protection device 4, one side of the limiting protection device 4 opposite to the first joint yoke 3 is provided with a second joint yoke 3, one side of the universal joint body 1 opposite to the second joint yoke is fixedly connected with a mounting plate, and the front side and the rear side of the second joint yoke 3 are respectively provided with a bearing.

During the use, install festival fork 2 at the transmission position through the mounting panel, at the driven in-process of universal joint, festival fork 2 drives the cross and rotates, and the cross drives festival fork two 3 and rotates, and festival fork two 3 rotates on the surface of bearing, and two 3 pivoted in-process spacing protection device 13 of festival fork are spacing to it and prevent its excessive rotation, and the section of thick bamboo fork on the cross universal joint main part 1 is connected festival fork two 3, transmits kinetic energy.
