Abstract
The utility model discloses a universal joint which comprises a first joint, a second joint and a universal joint pin. Two ends of the universal joint pin are connected on the first joint, and the other two ends of the universal joint pin are connected on the second joint. The first joint and the second joint are both formed by a connecting end face and two connecting lugs. The connecting end face and the two connecting lugs of each joint are formed by punching integrally. The connecting lugs are connected with two ends of each connecting end face of each joint to form a U shape. The universal joint does not require the step of machining through a milling machine, the joints are formed by punching directly, connecting rods are riveted or welded on the joints, operation is simple and convenient, and machining cost is reduced.
Description
Technical field
The utility model relates to a kind of universal-joint spindle.
Background technique
Universal-joint spindle also claims universal joint, refers to utilize device such as ball-type realizing the axle power output of different direction, and it also is on the automobile one very vitals.Universal-joint spindle English name universal joint is the parts of realizing the varied angle transmission of power, is used for needing to change the position of transmission axial direction, and it is " joint " parts of the universal driving device of automobile driving system.
Existing modal, most popular universal-joint spindle is produced as Xiangshan He Pu space Xiang machine tool accessory factory, the connection joint of this universal-joint spindle processes two engaging lugs by steel pipe through milling machine, and then at steel pipe boring assembling miscellaneous part, or be connected with miscellaneous part.This complex manufacturing, the processing cost height.
The model utility content
Technical problem to be solved in the utility model provides a kind of universal-joint spindle, and this universal-joint spindle production technology is simple, easy to process.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of universal-joint spindle, comprise that first connects joint, second connection joint and the cross axle, the two ends of described cross axle are connected first and connect on the joint, it is connected on the second connection joint at two ends in addition, it all is to constitute by connecting end face and two engaging lugs that the described first connection joint, second connects joint, and described connection end face and two engaging lugs are formed by whole punching press, and the two ends that described engaging lug is connected the connection end face form the U font.
Described cross axle comprises first bearing pin and second bearing pin, and the two ends of described first bearing pin are connected first and connect on the joint, and described second bearing pin radially crosses first bearing pin along first bearing pin, and its two ends are connected second and connect on the joint.
Be arranged with metal ring on described first bearing pin, described second bearing pin along first bearing pin radially cross first bearing pin time, also radially cross metal ring along metal ring.
Being shaped as of described connection end face is circular or square.

The utility model does not need through the milling machine processing steps, connects joint and directly is stamped to form, and connecting rod is riveted or is welded on and connects on the joint, and is simple to operation, reduces processing cost.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, universal-joint spindle comprises that first connects joint 1, second connection joint 2 and the cross axle, described cross axle comprises first bearing pin 5 and second bearing pin 6, the two ends of described first bearing pin 5 are connected first and connect on the joint 1, described second bearing pin 6 radially crosses first bearing pin 5 along first bearing pin 5, and its two ends are connected second and connect on the joint 2.
It all is to constitute by connecting end face 3 and two engaging lugs 4 that the described first connection joint 1, second connects joint 2, described connection end face 3 and two engaging lugs 4 are formed by whole punching press, being shaped as of described connection end face 3 is circular or square, and engaging lug 4 is connected the two ends that connect end face 3 and forms the U font.
Connect end face 3 and be connected with connecting rod, riveted joint or welding between described connection end face 3 and the connecting rod, described connecting rod can be scavenger valve bar, four angle head bars etc., connects the connection end face riveted joint of joint or welds four angle head bars 9 as first riveted joint of connection end face or the welding oil return valve rod 8, the second that connects joint 1.
In order to strengthen the intensity of first bearing pin 5, in addition, limit second bearing pin 6 along the scope of the radial motion of first bearing pin 5 scope that radially swings of first bearing pin 5 (namely along), be arranged with metal ring 7 on first bearing pin 5, described second bearing pin 6 along first bearing pin 5 radially cross first bearing pin 5 time, also radially cross metal ring 7 along metal ring 7.
In addition, the shape of engaging lug 4 can be set to convex shape, and the wider portion of convex shape engaging lug 4 can be used for the range of movement that restriction connects joint, also can increase the intensity of engaging lug 4.
Above-described embodiment limits the utility model never in any form, and every employing is equal to replaces or technological scheme that the mode of equivalent transformation obtains all drops in the protection domain of the present utility model.
