Abstract
The utility model relates to a toe-in regulating rod. The toe-in regulating rod comprises a long hexagon nut, a long rod body and a short rod body, wherein two ends of the long hexagon nut are respectively in thread connection with the ends of the long rod body and the short rod body, and are respectively locked through a first locking nut and a second locking nut; one section of protection cylinder is formed on the first locking nut through extending upwards; the inner hole diameter of the protection cylinder is slightly greater than the nominal diameter of the end thread of the long rod body; the end thread of the long rod body is totally covered by the protection cylinder; and the second locking nut has the same structure with the first locking nut. The toe-in regulating rod can prevent the rod body thread of the toe-in rod from being corroded.
Description
Technical field
The utility model relates to the member of a kind of automobile four-wheel location, is specifically related to a kind of prenex adjust bar.
Background technology
Along with expanding economy, the raising of people's living standard, automobile has become the essential traffic instrument of people's trip.Yet automobile needs better NVH performance, increasing manned vehicle rear suspension adopts the suspension frame structure of many link-types.In order to regulate toeing-in, part rear overhang rack has adopted the prenex adjust bar of threaded adjusting mode.Adjustable toein control lever as disclosed in CN1994802A, two body of rod terminations of this toein control lever and long hexagonal nut link together, and lock by jam nut, and now, along with the rotation of long hexagonal nut, this toein control lever is by elongated or shorten.
In this toein control lever, the effect of jam nut is after the length of prenex bar is determined, it is loosening to prevent it by the long hexagonal nut of locking, and unclamps after jam nut, can regulate again the position of long hexagonal nut.Although this mode is easy, due to body of rod termination not with the screw thread long term exposure of jam nut junction outside, after the corrosion such as airborne muddy water, greasy dirt, make screw thread destroyed, cause jam nut looseness.Thereby make long hexagonal nut looseness.Toe-in cannot meet the requirements of fixing value.
In sum, traditional toein control lever is not very reliable, need to improve.
Summary of the invention
The purpose of this utility model is to provide a kind of prenex adjust bar that prevents the corrosion of prenex club shaft ends screw.
A kind of prenex adjust bar described in the utility model, comprise long hexagonal nut, stock body and quarter butt body, the two ends of described long hexagonal nut are connected with the ends screw of quarter butt body with stock body respectively, lock by the first jam nut and the second jam nut respectively at the two ends of described long hexagonal nut, on described the first jam nut, extend to form a segment protect cylinder, the diameter of bore of described protection cylinder is slightly larger than the nominal diameter of stock body ends screw, and described protection cylinder covers the screw thread of stock body termination completely; Described the second jam nut is identical with the first locking nut structure.
The utlity model has following advantage:
The utility model has improved locking member; the rear end reality of this locking member provides a kind of proofing dust and protecting for the screw thread of quarter butt body and stock body termination; it can effectively prevent that screw thread is exposed in rugged environment, slows down the speed that screw thread is corroded, and improves the service life of whole prenex adjust bar.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the first locking member in Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Referring to a kind of prenex adjust bar shown in Fig. 1 and Fig. 2, comprise long hexagonal nut 4, stock body 6 and quarter butt body 2, one end of described stock body 6 is connected with drg, and the other end is termination, is connected with the threaded one end of long hexagonal nut 4; One end of described quarter butt body 2 is connected with lining, and the other end is termination, is threaded with the other end of long hexagonal nut 4; The two ends of described long hexagonal nut 4 are respectively by the first jam nut 5 and the second jam nut 3 lockings.The first jam nut 5 as shown in Figure 2, extends to form a segment protect cylinder 52 on described the first jam nut 5, and an end of described the first jam nut 5 is tight lock part 51, and this tight lock part is provided with the negative thread coordinating with stock body 6 ends screws; The other end is for protecting cylinder 52, and the diameter of bore of this protection cylinder is slightly larger than the nominal diameter of stock body 6 ends screws, and the screw thread of stock body 6 terminations is covered completely.Described the second jam nut 3 is identical with the first jam nut 5 structures.On described the second jam nut 3, extend to form one section of second protection cylinder, an end of described the second jam nut 3 is the second tight lock part, and this second tight lock part is provided with the negative thread coordinating with quarter butt body 2 ends screws; The other end is the second protection cylinder, and the diameter of bore of this second protection cylinder is slightly larger than the nominal diameter of quarter butt body 2 ends screws, and the screw thread of quarter butt body 2 terminations is covered completely.
The protection cylinder reality of described locking member 5 provides a kind of proofing dust and protecting for the screw thread of quarter butt body 2 and stock body 6 terminations, and it can effectively prevent that screw thread is exposed in rugged environment, slows down the speed that screw thread is corroded, and improves the service life of whole prenex adjust bar.
