Abstract
The utility model discloses a shock absorption adjusting screw rod, which comprises a screw rod. One end of the screw rod is a threaded end, and the other end of the screw rod is a cylindrical end. The threaded end of the screw rod is wrapped by a plastic coating layer of which the outer surface has a toothed structure with a semicircular section. The shock absorption adjusting screw rod is simple in structure and convenient to use and mount, the problem of large transverse gap of the conventional design is solved, shock is reduced, gearshift comfort is improved, and tooth alignment phenomena are reduced.
Description
Technical field
The utility model relates to the automobile equipment field, particularly a kind of damping adjusting screw rod.
Background technique
Automobile guy cable divides the engage a gear drag-line, clutch cable, brake line definition: be used for pulling and change Transmission gear, clutch, the steel wire cable of brake.
Act on behalf of pull bar and handle machine run speed or tractive force such as changing lathe, automobile, tractor, the device of goods or door lock is by different the forming of many diameter; Usually be contained in engine and carburetor, fuel pump, closure, speed changer, clutch is on the wheel hub.
Development along with society, automobile has become the main traffic tool of people, in the manual transmission gear shift car of present most of engine behind front wheels, it need to adopt the gear shifting rotary arm of gear shift pulling cable operation speed changer, to change Transmission gear, because manual gear is more, therefore necessarily require the gear shift pulling cable stroke very accurate, otherwise can cause the gear shift dislocation, thereby the important content of each automobile factory's research is how accurate adjustment selects the gear shift pulling cable stroke.
At present, when automobile gear shifting inhaul cable is connected with gearbox, owing to making and assembly error, even if cause both also to reduce can not be assembled together or the be assembled together comfort property of gearshift, so often adopt adjustable mechanism during assembling shifting drag-line.
Existing damping adjusting screw rod complex structure, use inconvenient, lateral clearance is excessive, during gearshift loud, the easy generation of vibrations to the tooth phenomenon.
The model utility content
The technical problems to be solved in the utility model provides a kind of simple in structure, easy to use, high a kind of damping controlling mechanism of gearshift comfort level.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of damping adjusting screw rod comprises screw rod, and an end of described screw rod is threaded end, and the other end of described screw rod is cylindrical end; Described screw flight end is enclosed with plastic clad
Preferably, the outer surface of described plastic clad is tooth-shape structure.
Preferably, described tooth-shape structure is comprised of the complex root tooth bar
Preferably, the cross section of described tooth bar is semicircle.
By technique scheme, the beneficial effects of the utility model are:
The utility model is simple in structure, easy to use, solved intrinsic each tooth-shape structure lateral clearance excessive, reduced vibrations, the travelling comfort when having improved gearshift, reduced the tooth phenomenon, be convenient to install.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the utility model structural representation.
Numeral and the represented corresponding part title of letter among the figure:
10, screw rod 20, threaded end 30, cylindrical end 40, plastic clad 50, tooth bar
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to shown in Figure 1, a kind of damping adjusting screw rod of the utility model comprises screw rod 10, and an end of screw rod 10 is threaded end 20, and the other end of screw rod 10 is cylindrical end 30, and the threaded end 20 of screw rod 10 is enclosed with the plastic clad 40 that is complementary with the threaded end worm structure.
The outer surface of the utility model plastic clad is tooth-shape structure, and tooth-shape structure is comprised of complex root tooth bar 50, and the cross section of tooth bar 50 is semicircle.
Between each tooth bar 50 of the utility model plastic clad distance less than the distance between threaded end 20 each screw thread bar, the precision when it uses is high.
The utility model is when cooperating with retainer because the effect of semicircle tooth bar 50, its reduced when using to the tooth phenomenon.
The utility model assembly precision is high, processing cost is low, it is convenient to install.
Above demonstration and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
