Comprises a rotating shaft, a drop-proof cover, a left-joint fork, a long pin, a cross block and a right-joint fork; the rotating shaft is arranged in the groove of the left-section fork, and the anti-release cover is fixed on the left-section fork through a screw to limit the axial movement of the rotating shaft; the left-section fork is hinged with the right-section fork through a long pin and a cross block to form a cross universal joint. The utility model discloses possess advantages such as compact structure, small, solved under the equal volume can transmit big push-and-pull power and can realize the problem of big pivot angle.
Description
Technical Field
The utility model relates to an automobile transmission system technical field specifically is a rotatable big pivot angle universal joint.
Background
The conventional universal joints can be roughly divided into a cross universal joint and a spherical joint universal joint in structure, the cross universal joint can transmit torque and push-pull force, part of the spherical joint universal joint can transmit torque and push-pull force, and part of the spherical joint universal joint can not transmit torque but can transmit push-pull force, but the spherical joint universal joint which can not transmit torque but can transmit push-pull force is generally large in volume, the size of the push-pull force which can be transmitted under the condition of small volume is limited, and the universal joint is not suitable for places with narrow arrangement space.
Disclosure of Invention
The utility model provides a not enough to prior art, the utility model provides a rotatable big pivot angle universal joint possesses advantages such as compact structure, small, has solved under the equal volume can transmit big push-and-pull power and can realize the problem of big pivot angle around moving.
In order to achieve the above object, the utility model provides a following technical scheme: a rotatable universal joint with a large swing angle comprises a rotating shaft, a drop-proof cover, a left-joint fork, a long pin, a cross block and a right-joint fork; the left-joint fork is characterized in that a rotating shaft is arranged in a left-joint fork groove, and the root of the left-joint fork is hinged with the rotating shaft; the anti-release cover is fixed on the left-section fork through a screw to limit the axial movement of the rotating shaft; the left-section fork is hinged with the right-section fork through a long pin and a cross block to form a cross universal joint.
Compared with the prior art, the utility model discloses possess following beneficial effect:
1. according to the rotatable large-swing-angle universal joint, the root of the left-section fork is hinged with the rotating shaft, the left-section fork can rotate freely under the condition of realizing large swing angle orbiting, the size is small, and a specific transmission function can be completed in a narrow space.
2. When the rotating shaft is fixed, the left-section fork can do circular motion around the rotating shaft, and the right-section fork can do circular rotation with a large swing angle without dead angle limitation.
Drawings
Fig. 1 is a structural sectional view of the present invention.
The reference numbers illustrate: 1-rotating shaft, 2-anti-drop cover, 3-screw, 4-left-joint fork, 5-long pin, 6-cross block and 7-right-joint fork.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in FIG. 1, a rotatable universal joint with a large swing angle comprises a rotating shaft 1, a release-preventing cover 2, a screw 3, a left yoke 4, a long pin 5, a cross block 6 and a right yoke 7;
the rotating shaft 1 is arranged in a groove of a left-section fork 4, and the anti-release cover 2 is fixed on the left-section fork 4 through a screw 3 to limit the axial movement of the rotating shaft 1; the left yoke 4 is hinged with the right yoke 7 through a long pin 5 and a cross block 6 to form a cross universal joint.
The utility model discloses a working process:
the rotary shaft 1 of the rotary large-swing-angle universal joint is fixedly connected with a rack of a steering gear box through threads, and the right-section fork 7 is hinged with a vehicle steering joint through a ball joint. When the rotating shaft 1 is fixed, the left yoke 4 can do circular motion around the rotating shaft 1, and the right yoke 7 can do circular rotation with a large swing angle without dead angle limitation.
When the wheels jump up and down along with the fluctuation of the road surface, the universal joint can realize large swing angle rotation, and can also transmit rack force of a steering gear to the wheels to realize steering. The structure can transmit large push-pull force and realize large swing angle orbiting, has small volume and is beneficial to realizing specific transmission action in narrow arrangement space;
the above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are all covered by the protection scope of the present invention.
