Abstract
The utility model discloses a universal joint fork head which comprises a pair of universal joint forks (1), and a connecting shaft (2) and a cross shaft (3) which are connected with the universal joint forks (1). One end of the connecting shaft is an inclined surface (4), and a threaded rod (5) penetrates through the connecting shaft (2) to be connected with the universal joint forks (1). By adopting the technical scheme, the universal joint fork head only needs to replace a fractured drive shaft under the condition that the drive shaft is fractured, needs not to replace the whole universal joint drive device greatly lowers production cost, reduces loss, relatively wins benefits for a vehicle owner, is more convenient and quick when in repairing and replacing the fractured drive rod, saves time, and has simple structure and high intensity.
Description
Technical field
The utility model belongs to the technical field of universal drive shaft device, and more particularly, the utility model relates to a kind of jaw of universal joint.
Background technique
Universal drive shaft is connected with cross axle by universal-joint fork at present, and universal-joint fork and transmission shaft are welded; Because transmission shaft is to be welded to connect with whole axle and universal-joint fork, vehicle especially the load-carrying vehicle heavy burden greatly, in rugged travels down of jolting, the transmission shaft power easy-rupturing that is hit.Just must change whole transmission shaft and universal joint once crack conditions takes place, lose very greatly, waste very much.
The model utility content
Problem to be solved in the utility model provides a kind of universal joint jaw, its objective is to change whole transmission shaft and universal joint behind drive shafts fracture, has saved cost, has significantly reduced loss.
To achieve these goals, the technological scheme taked of the utility model is:
This universal joint jaw provided by the utility model comprises coupling shaft and cross axle that a pair of universal-joint fork links to each other with it, and described coupling shaft one end is the inclined-plane, and threaded stem is arranged in the coupling shaft.
For making the utility model more perfect, more detailed and concrete technological scheme below also further having proposed, to obtain best practical effect, realize goal of the invention better, and improve novelty of the present utility model and creativeness:
The inclined-plane of described coupling shaft one end has a certain degree.
The angle on described inclined-plane is 45 °.
Described threaded stem one end is a spline, and another part is a screw thread; Threaded stem stretches out outside the coupling shaft.
It is that spline is connected with universal-joint fork that described threaded stem passes coupling shaft, and fixes with jump ring.
Described universal-joint fork is cast, and two convex bodys are arranged in its hub portion, and two convex bodys be arranged in parallel, and the surface is the plane.
The utility model adopts technique scheme, under the situation of drive shafts fracture, only needs to change the transmission shaft of fracture, needn't change whole card gear, greatly reduces cost, has reduced loss, has got interests for the car owner comparatively speaking; And, saved the time repairing more convenient and quicker on the replacing fracture transmission shaft; Simple in structure, the intensity height.
Description of drawings
Below expressed content of the accompanying drawing of this specification and the mark among the figure are made brief description:
Fig. 1 is a structural representation of the present utility model.
Be labeled as among the figure:
1, universal-joint fork, 2, coupling shaft, 3, cross axle, 4, the inclined-plane, 5, threaded stem, 6, hub portion, 7, convex body, 8, spline.
Embodiment
Contrast accompanying drawing below, by description to embodiment, to effect and working principle, the manufacturing process of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present utility model, technological scheme had more complete, accurate and deep understanding to help those skilled in the art.
As the structure of the present utility model that Fig. 1 expresses, be a kind of universal joint jaw, comprise coupling shaft 2 and cross axle 3 that a pair of universal-joint fork 1 links to each other with it.
In order to solve the problem that exists at the described present known technology of this specification background technique part and to overcome its defective, realize saving cost, the technological scheme that replacing makes things convenient for goal of the invention, the utility model to take is:
This universal joint jaw provided by the utility model has threaded stem 5 in the described coupling shaft 2, and coupling shaft 2 one ends are inclined-plane 4.
The above-mentioned universal joint jaw that the utility model provides, its coupling shaft 2 is connected with transmission shaft (not drawing among the figure); Transmission shaft one end center hole only need process internal thread, and the end face of threaded end is processed into the inclined-plane; Threaded stem 5 matches with the transmission shaft internal thread, and linear state matches with the inclined-plane of transmission shaft on the inclined-plane 4 of coupling shaft 2.During assembling, earlier threaded stem 5 is screwed in the transmission shaft, the inclined-plane 4 that makes coupling shaft 2 then fits in linear state with the inclined-plane of transmission shaft, at this moment with the other end spline 8 of threaded stem 5 with after the spline of universal-joint fork 1 matches, fix to get final product with jump ring.
Adopt technique scheme, assembling is simple, changes convenient and swiftly, for the car owner has saved cost, has got interests and time.
Be the concrete exemplifying embodiment that the utility model provides below, for those skilled in the art's reference and selecting for use when implementing the utility model:
Embodiment one:
The angle on the inclined-plane 4 of coupling shaft 2 one ends described in the utility model is 0 °-90 °.
The angle on inclined-plane 4 can be greater than 0 ° of scope less than 90 °, and the inclined-plane of the inclined-plane 4 of coupling shaft 2 and the transmission shaft scope that can cooperate is with big like this.
Embodiment two:
The angle on inclined-plane 4 described in the utility model is 45 °.
It is optimal angle that the angle on inclined-plane 4 is 45 °, at this moment matches with transmission shaft, and the torsion that is subjected to distributes the most even; One root timber material cuts from miter angle, and can be used as two inclined-planes is the axle use of miter angle, has saved material, has reduced waste.
Embodiment three:
Threaded stem 5 one ends described in the utility model are spline 8, and another part is a screw thread; Threaded stem 5 stretches out outside the coupling shaft 2.
Threaded stem 5 one ends are made spline 8, be convenient to be connected, and adopt the spline attachment security reliable with universal-joint fork 1; Another part is made screw thread, and convenient and transmission shaft assembles, and coupling shaft 2 and transmission shaft are fixed, and limits its slip and comes off.
Embodiment four:
Threaded stem 5 described in the utility model passes coupling shaft 2 and universal-joint fork 1 for spline is connected, and fixes with jump ring.
The same embodiment three is described; Simple in structure, easy to process, assembling is quick.
Embodiment five:
Cast at universal-joint fork 1 described in the utility model, have 7, two convex bodys 7 of two convex bodys to be arranged in parallel in its hub portion 6, the surface is the plane.
