Abstract
The utility model discloses a kind of novel automobile vibration damper external connecting sleeve, comprise external connecting sleeve body, described external connecting sleeve body upper surface is provided with convex tendon.The utility model structure is simple, reasonable in design, increase the fitting area with vehicle body attachment face, decrease the distortion of shock absorber external connecting sleeve and vehicle body attachment face in the use procedure of high strength reverse load, improve shock absorber reliability of service and stability, extend the service life of shock absorber, effectively reduce the fault rate after sale of shock absorber.
Description
Technical field
The utility model relates to a kind of coupling sleeve, particularly relates to a kind of vehicle shock absorber external connecting sleeve.
Background technology
In the design process of shock absorber for vehicle, see Fig. 1, external connecting sleeve assembly comprises external connecting sleeve 1, shock pad 2, interior coupling sleeve and dust collar.Wherein the function of external connecting sleeve 1 is: be 1. fixedly connected bolt 3; 2. mounting plane and vehicle body mounting plane are fitted, and bearing vehicle body is transmitted to the weight of shock absorber; 3. coordinate with shock pad.
After vehicle assembling shock absorber, fit tightly, therefore to external connecting sleeve upper surface planarity requirements higher (being generally 0.2) as the upper surface of the external connecting sleeve be connected with vehicle body and vehicle body end face.The external connecting sleeve of conventional confguration has the following disadvantages: 1. because external connecting sleeve material is SPCC, its processing mode is punch process, and therefore in the course of processing, external connecting sleeve upper surface planeness not easily ensures, and conformability is slightly poor; 2. vehicle body is connected with the external connecting sleeve of shock absorber by attachment bolt, in attachment bolt installation process, utilize external impacts to tighten coupling nut attachment bolt is fixed, due to the external force impact that is hit, after assembling, external connecting sleeve upper surface and vehicle body end face are fitted not tight, reality is that external connecting sleeve upper surface, attachment bolt place and vehicle body end face are fitted, but not the whole upper surface of external connecting sleeve and vehicle body end face are fitted; 3. shock absorber assembling after and vehicle body fit undesirable, external connecting sleeve upper surface, attachment bolt place area of contact is less, in the use procedure of high strength reverse load, attachment bolt place easily deforms, and after using a period of time, attachment bolt place can produce microclearance so that loosen and cause abnormal sound.
Therefore, the direction becoming these those skilled in the art and make great efforts how is solved the problems of the technologies described above.
Utility model content
The purpose of this utility model is just to provide a kind of novel automobile vibration damper external connecting sleeve, can solve above-mentioned the deficiencies in the prior art part completely.
The purpose of this utility model is realized by following technical proposals:
A kind of novel automobile vibration damper external connecting sleeve, comprises external connecting sleeve body, it is characterized in that: described external connecting sleeve body upper surface is provided with convex tendon.
Further, in the middle of described external connecting sleeve body, be provided with assembling circular hole, the external connecting sleeve body outside assembling circular hole be provided with coupling bolt hole, the external connecting sleeve body between assembling circular hole and coupling bolt hole evenly arranges 3 convex tendons.
Further, with assembling circular hole concentric 3 convex tendons are circumferentially evenly set, and described convex tendon is the circular arc convex tendon mated with this circumference.
Further, described convex tendon is the convex tendon adopting Sheet Metal Forming Technology shaping.
Compared with prior art, the beneficial effects of the utility model are: structure is simple, reasonable in design, increase the fitting area with vehicle body attachment face, decrease the distortion of shock absorber external connecting sleeve and vehicle body attachment face in the use procedure of high strength reverse load, improve shock absorber reliability of service and stability, extend the service life of shock absorber, effectively reduce the fault rate after sale of shock absorber.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art external connecting sleeve assembly;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the A-A cross-sectional view in Fig. 2;
Fig. 4 is the partial enlarged drawing at I place in Fig. 3.
Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the utility model is further described.
As shown in Figures 2 to 4, a kind of novel automobile vibration damper external connecting sleeve, comprises external connecting sleeve body 101, and described external connecting sleeve body 101 upper surface is provided with convex tendon 102, and the end face of described convex tendon 102 is the plane parallel with external connecting sleeve body 101 upper surface.
Concretely, assembling circular hole 103 is provided with in the middle of described external connecting sleeve body 101, external connecting sleeve body 101 outside assembling circular hole 103 is provided with 3 coupling bolt holes 104, the external connecting sleeve body 101 between assembling circular hole 103 and coupling bolt hole 104 arranges 3 convex tendons 102.These 3 convex tendons 102 are evenly arranged on the circumference 105 concentric with assembling circular hole 103, and described convex tendon 102 is the circular arc convex tendon mated with this circumference 105.
Described convex tendon 102 can adopt Sheet Metal Forming Technology shaping, and these 3 convex tendons 102 more easily ensure precision and planeness in punch process.After the assembling of vehicle assembling shock absorber, article 3, convex tendon 102 and the upper surface at the attachment bolt place be arranged in coupling bolt hole 104 form 6 places and vehicle body and install the binding face that end face fits tightly, thus increase the area of fitting with vehicle body attachment face, decrease the distortion of shock absorber external connecting sleeve and vehicle body attachment face in high strength, reverse load use procedure, improve the service life of shock absorber.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
