Description
Technical field
The utility model is related to engine clutch field, more particularly to a kind of connection cushion block of clutch fan.
Background technology
Clutch fan connection cushion block major function fixes support clutch fan component, while ensureing clutch fan group
The axially mounted size of part.Because some special whole machines arrange demand, the structural requirement to connecting cushion block is compact to design, while
Also need to subsidiary some special functions.
Existing connection cushion block structure unitary function, it is impossible to meet different whole machine arrangement demands.
The information for being disclosed in the background section is merely intended to increase the understanding to general background of the present utility model, and
It is not construed as recognizing or implying in any form that the information structure has been existing well known to persons skilled in the art
Technology.
Utility model content
The purpose of this utility model is to provide a kind of connection cushion block of simple and reasonable clutch fan, the clutch
The connection cushion block functional diversities of device fan, highly versatile substantially reduces the cost of whole machine, while improve the reliability of whole machine
Property.
To achieve the above object, the utility model provides a kind of connection cushion block of clutch fan, including：Fan shaft is pacified
Dress end, it circumferentially offers multiple and crosses nail, and sets up positioning spigot, and the fan shaft installation end passes through mistake described in bolt-through
Nail is fixed on the front end of fan shaft part；The fan shaft installation end is integrated with the race for driving air conditioner；And
Clutch fan component installation end, it has external screw thread, is screwed for the internal thread with silicon oil clutch fan component and tightened.
Preferably, in above-mentioned technical proposal, it is four for circumferentially opening up to cross nail.
Preferably, in above-mentioned technical proposal, fan shaft installation end circumferentially offers multiple lightening holes, the lightening hole with
Cross nail interval setting.
Preferably, in above-mentioned technical proposal, external screw thread is left hand thread.
Compared with prior art, the utility model has the advantages that：
1st, the connection cushion block and fan shaft part link position of the clutch fan increase the design of positioning spigot, it is ensured that see
Parts installation dimension precision, reduces the unbalancing value of assembly parts；
2nd, the connection cushion block and silicon oil clutch fan component of the clutch fan are tightened using threaded engagement, are met whole
Car installs the requirement of the installation accuracy of the axial distance of end face to fan to body；
3rd, the connection cushion block of the clutch fan is integrated with polywedge bet race, reduces amount of parts and assembling, reduces
Cost.
Brief description of the drawings
Fig. 1 is the main structure diagram of the connection cushion block of clutch fan of the present utility model.
Fig. 2 is the cross section structure diagram of the connection cushion block of clutch fan of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail, it is to be understood that this practicality
New protection domain is not limited by specific embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " including " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other units
Part or other parts.
As depicted in figs. 1 and 2, the connection cushion block of the clutch fan according to the utility model specific embodiment is specific
Including：Fan shaft installation end and clutch fan component installation end, wherein, fan shaft installation end sets up positioning spigot 5, by spiral shell
When bolt penetrates nail and is fixed on the front end of fan shaft part, connection cushion block follows fan shaft part to do rotation fortune at a high speed
Dynamic, positioning spigot 5 ensure that parts installation dimension precision, reduce the unbalancing value of assembly parts.While fan shaft
Installation end is integrated with polywedge bet race, reduces amount of parts and assembling, reduces cost.Clutch fan component installation end with
Silicon oil clutch fan component tightened using threaded engagement, meets the axial distance that vehicle installs end face to fan to body
The requirement of installation accuracy.
Specifically, fan shaft installation end circumferentially offers multiple and crosses nail 3, and sets up positioning spigot 5, by bolt
When penetrating nail and being fixed on the front end of fan shaft part, connection cushion block follows fan shaft part to do high speed rotary motion,
Positioning spigot 5 ensure that parts installation dimension precision, reduce the unbalancing value of assembly parts, meet rotation at a high speed
Parts are for unbalancing value high request after assembling.Preferably, it is four for circumferentially opening up to cross nail 3.Bolt is M10
Bolt.Fan shaft installation end circumferentially offers multiple lightening holes.Preferably, lightening hole is four.Between lightening hole and excessively nail 3
Every setting.
Meanwhile, fan shaft installation end is integrated with polywedge bet race 4, and front end wheel train is two-layer train, and polywedge bet race 4 belongs to
Outermost layer train, drives air conditioner, so as to reduce amount of parts and assembling, reduces cost for fan shaft part.
Arrangement requirement silicon oil clutch fan component is arranged on connection cushion block front end, because vehicle is to fan to body
The axial distance requirement for installing end face is compact, has no idea to use spiral shell between silicon oil clutch fan component and connection cushion block
Bolt added the design of nail (as connection cushion block is connected with fan shaft part) to be fixedly connected, this in order to solve
Arrangement, clutch fan component installation end has external screw thread 1, is screwed for the internal thread with silicon oil clutch fan component stubborn
Tightly, requirement of the vehicle to fan to the installation accuracy of the axial distance of body installation end face is met.
Preferably, external screw thread 1 be designed to it is left-handed, the internal thread of silicon oil clutch fan component be designed to it is left-handed, due to silicon
Oily clutch fan component is turn clockwise (from terms of motor head), fan during Acceleration of starting is operated, fan
The rotary inertia of generation makes screw thread coordinate screw-down torque increasing, but causes wind to prevent engine operating from stopping working immediately
Fan makes Screw assembly fall torque due to the active force clockwise that rotary inertia brings, while requiring to use spiral shell in installing fixation procedure
Line fastening glue.
To sum up, the connection cushion block functional diversities of the clutch fan, highly versatile substantially reduces the cost of whole machine, together
When improve the reliability of whole machine.
The foregoing description to specific illustrative embodiment of the present utility model be in order to illustrate and illustration purpose.These
Description is not wishing to for the utility model to be defined to disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can carry out
It is many to change and change.The purpose of selecting and describing the exemplary embodiment is that explaining certain principles of the present utility model
And its practical application, so that those skilled in the art can realize and utilize a variety of examples of the present utility model
Property embodiment and a variety of selections and change.Scope of the present utility model is intended to by claims and its waits similar shape
Formula is limited.
