Background

The shock absorber suppresses the shock when the spring absorbs shock and then rebounds and the impact from the road surface, and is widely used for automobiles. The damping of the vibration of the frame and the vehicle body can be accelerated to improve the driving smoothness of the vehicle. The connection mode of the lifting lug and the frame of the common automobile shock absorber is that rubber is filled in the lifting lug hole or a joint bearing is used, so that the universal rotary connection effect is achieved. But with the road condition jolt degree increase, the rubber deformation is serious or the joint bearing is not wear-resisting, so that the shock absorber lifting lug is not durable.

In order to realize the above-mentioned purpose, the utility model provides a fixed pivot formula universal joint for automobile shock absorber ware, including first rotatory axle sleeve, second rotation axis and the mount pad of shaft coupling, the first articulated portion of mount pad is articulated with first rotatory axle sleeve, first rotatory axle sleeve and frame fixed connection, the articulated portion of second of mount pad articulates there is the second rotation axis, first rotatory axle sleeve with contained angle between the second rotation axis is 90, the both ends of second rotation axis are articulated with the mounting groove lateral wall of installation pole, the cross-section of mounting groove is the U type, the second articulated portion is in one end in the mounting groove is the arc.

Preferably, the first hinge part is circular in cross section, two sides of the first hinge part are connected with a fixing ring, and the fixing ring is hinged with the first rotating shaft sleeve.

Preferably, the frame is connected with the first rotating shaft sleeve through a bolt, and mounting holes connected with the bolt are formed in two ends of the first rotating shaft sleeve.

Preferably, one end of the mounting rod, which is far away from the mounting groove, is connected with a shock absorber.

Therefore, the utility model adopts the above structure a fixed pivot formula universal joint for automobile shock absorber ware, the bumper shock absorber can be followed first rotation axis and second rotation axis and independently rotated for the shaft coupling has great angle compensation ability, and the lug incorruptibility increases increase of service life.

The technical solution of the present invention is further described in detail by the accompanying drawings and examples.

Fig. 1 is the utility model relates to a car bumper shock absorber is with fixed pivot formula universal joint looks section, fig. 2 is the utility model relates to a car bumper shock absorber is with fixed pivot formula universal joint (not drawing frame, first rotation axis, first rotatory axle sleeve and solid fixed ring) side section-view, as shown in the figure, a car bumper shock absorber is with fixed pivot formula universal joint, including the first rotation axis 1, the second rotation axis 2 and the mount pad 3 of shaft coupling. The first hinge part 4 of the mounting base 3 is hinged with a first rotating shaft sleeve 10, a first rotating shaft 1 hinged in the first rotating shaft sleeve 10 is fixedly connected with the frame 5, and the second hinge part 6 of the mounting base 3 is hinged with a second rotating shaft 2. The included angle between the first rotating shaft 1 and the second rotating shaft 2 is 90 degrees, and two ends of the second rotating shaft 2 are hinged with the side wall of the mounting groove 8 of the mounting rod 7. The section of the mounting groove 8 is U-shaped, and one end of the second hinge part 6 in the mounting groove 8 is arc-shaped. The mounting seat 3 drives the mounting rod 7 to rotate along the first rotating shaft 1, the mounting rod 7 can rotate along the second rotating shaft 2, and the mounting rod 7 can independently rotate along the first rotating shaft 1 and the second rotating shaft 2. The shock absorber moves along with the installation rod 7 after being connected, so that the effect of universal rotation is achieved. The mounting base 3 is connected with the frame 5 through the first rotating shaft 1, and then the connection of the shock absorber and the frame 5 is realized. The arc structure of the second hinge part 6 is arranged so that the mounting rod 7 is not jammed when rotating along the second rotating shaft 2.

The first hinge part 4 is circular in section, the first rotary shaft sleeve 10 is connected with the two sides of the first hinge part 4 through a fixing ring 9, and the fixing ring 9 is hinged with the first rotary shaft 1. The first hinge portion 4 is shaped so that the mount 3 does not get jammed when rotated along the first rotation axis 1. The arrangement of the fixing ring 9 and the first rotary sleeve 10 prevents the mount 3 from being displaced when rotating along the first rotary shaft 1.

The frame 5 is connected with the first rotating shaft 1 through bolts, and mounting holes connected with the bolts are formed in two ends of the first rotating shaft 1.

The end of the mounting rod 7 far away from the mounting groove 8 is connected with the shock absorber.

Therefore, the utility model adopts the above structure a fixed pivot formula universal joint for automobile shock absorber ware, first rotation axis and second rotation axis independent rotation can be followed to the bumper shock absorber for the shaft coupling has great angle compensation ability, and the lug incorruptibility increases increase of service life.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention and not to limit the same, and although the present invention is described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: the technical solution of the present invention can still be modified or replaced by other equivalent means, and the modified technical solution can not be separated from the spirit and scope of the technical solution of the present invention.
