Abstract
The utility model discloses a heavy shock absorber which comprises a lower base connected with a vehicle bottom frame and an upper base connected with the bottom of a cargo compartment. The lower base is provided with a guide sleeve, a guide column matched with the guide sleeve in use is further arranged on the lower portion of the upper base, a screw penetrates through the top of the upper base, a nut is arranged on the position, on the top of the upper base, of the screw, a check ring is movably disposed on the position, below the upper base, of the screw, the check ring is disposed at the bottommost end of the screw through the nut, a shock-absorbing spring is arranged in the guide sleeve and is connected with the check ring, the guide sleeve and the guide column are oval, and the two sides of the guide sleeve and the two sides of the guide column are respectively provided with an observation opening. The heavy shock absorber is simple in structure and remarkable in shock absorbing effect and can prevent spring torsion caused by weight of the shock absorber.
Description
Technical field
The utility model relates to a kind of heavy damping device, belongs to mechanical field.
Background technique
The cargo vehicle of China once once take medium truck as main, " lacking heavily few light ".In recent years, this situation changes.Total trend is the output that the output of light truck has substantially exceeded medium truck, and heavy motor truck output proportion is also progressively increasing.And heavy motor truck is also more and more subject to the attention of manufacturing enterprise and industry.
Vibration damper on cargo vehicle is one of very important parts.It is mainly the damping to cargo vehicle institute's loading and automobile itself, vibration damper on cargo vehicle is all more common at present, weight due to cargo vehicle itself and institute's loading, tend to cause the spring distortion on vibration damper, the effective damping effect that vibration damper is reached, thus driver's safety affected.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of heavy damping device, and this apparatus structure is simple, and damping effect is remarkable, can avoid vibration damper to cause spring distortion because of weight.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of heavy damping device, it comprises lower that is connected with mounting, with the seat of honour being connected with loading space bottom, described lower is provided with guide sleeve, below the seat of honour, be also provided with a directional post being used in combination with guide sleeve, top, the described seat of honour is installed with a screw rod, on the screw rod at top, the seat of honour, be provided with a nut, on the screw rod of below, the described seat of honour, be movably equipped with a back-up ring, and back-up ring is located on screw rod by nut at screw rod lowermost end, in described guide sleeve, be provided with a damping spring, this damping spring is connected with back-up ring.
Described guide sleeve and directional post are shaped as ellipse, and have an observation panel in the both sides of guide sleeve and directional post.
The diameter of described observation panel is less than the diameter of damping spring.
The both sides of described lower are also respectively equipped with one for fixing fixing threaded hole.
The beneficial effects of the utility model are: by guide sleeve and directional post, damping spring is protected; thereby when the pressing down of weight; can not make damping spring occur twisted phenomena, thereby improve the whole using effect of damping device, the working life of yet having improved damping spring simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model plan view;
Fig. 3 is the cross-sectional structure schematic diagram of the utility model guide sleeve and directional post.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1-2, a kind of heavy damping device, it comprises lower 1 that is connected with mounting, with the seat of honour 2 being connected with loading space bottom, lower seat 1 is provided with guide sleeve 100, below the seat of honour 2, be also provided with a directional post 200 being used in combination with guide sleeve 100, 2 tops, the seat of honour are installed with a screw rod 3, on the screw rod 3 at 2 tops, the seat of honour, be provided with a nut 4, on the screw rod 3 of 2 belows, the seat of honour, be movably equipped with a back-up ring 5, and back-up ring 5 is located on screw rod 3 by nut 40 at screw rod 3 lowermost ends, in guide sleeve 100, be provided with a damping spring 6, this damping spring 6 is connected with back-up ring 5.The both sides at lower seat 1 and the seat of honour 2 are also respectively equipped with one for fixing fixedly spiral shell 101,201 holes.
As shown in Figure 3, guide sleeve 100 is ellipse with leading 200 to post shapes, and has an observation panel 102,202 in the both sides of guide sleeve 100 and directional post 200.The diameter of observation panel 102,202 is less than the diameter of damping spring 6.
In the utility model; by guide sleeve 100 and directional post 200, damping spring 6 is protected, thereby when the pressing down of weight, can not make damping spring 6 occur twisted phenomena; thereby improved the whole using effect of damping device, the working life of also having improved damping spring simultaneously.
More than show and described basic principle of the present utility model, 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 in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
