Abstract

The utility model discloses a location structure of model car transmission shaft, transmission shaft and turn to between the external member equipment and have rubber dirt proof boot and metal sleeve, the ball seat of transmission shaft front end has well emptying aperture and concave space, and well emptying aperture and concave space have a perfect understanding each other, be equipped with the inner space in turning to the external member, the inner space outer fringe is equipped with the perforation, wears to be equipped with the locating pin in the perforation, and the ball seat of transmission shaft front end is being put into in the inner space that turns to the external member, and the locating pin penetrates to concave space after running through the perforation, metal sleeve must overlap and put in locating pin both ends outer fringe, and the rubber dirt proof boot overlaps on turning to the external member in the axis of rotation simultaneously. Can prevent in locating pin both ends outer fringe that the locating pin from taking place to drop in the motion by metal sleeve system cover, the dirt proof boot can let the grease fill a performance lubrication action, and then can not produce high fever when operateing at a high speed to protective oil fat is infected with by dust can by this, and can reach reducing wear and increase of service life and conveniently tear open and trade the maintenance efficiency.

Description

The locating structure of model car power transmission shaft

Technical field

This utility model is related to a kind of positioning component, especially a kind of locating structure of model car power transmission shaft.

Background technology

Press, about the power transmission shaft positioning architecture in model car, that is, refer to the connection positioning between power transmission shaft a and steering external member b, System is hubbed at by the pin joint seat a1 of the be in u shape in power transmission shaft a front end turns to external member b, wherein in the pin joint seat a1 of u shape and assemble There is sleeve piece c, so that the extension b1 of steering external member b two relative position must be pivoted (such as in crosswise with the pin joint seat a1 of power transmission shaft a First and second figure)；Due to being to need grease to slide with profit between power transmission shaft a and steering external member b, think and running up Shi Buhui produces hyperpyrexia.

But be exposed in car body with such assembling morphology system, so that coated between power transmission shaft a and steering external member b Oils and fatss become easily infected by dust, both losses will be caused in the course of time, thus between the two produce gap and produce and rock, Virtually just consume driving force, furthermore be only to be worn by alignment pin d to position between power transmission shaft a and steering external member b, so that Under the vibrations situation of quick motion for a long time, alignment pin d will be caused may to get loose, and need whole group part to change, this It is a burden on funds really for user.

Utility model content

Therefore, applicant just develops this case utility model, and files an application.Wherein

The purpose of this utility model, is to provide a kind of locating structure of model car power transmission shaft, means by power transmission shaft and steering The locator of connection between external member, by when power transmission shaft is with turning to external member and being pivoted, and by a metal sleeve and dirt-proof boot Under cladding, you can prevent alignment pin from will not fall off at the volley, and oils and fatss can be allowed to fill part performance lubrication, and can protect Oils and fatss will not be infected with by dust, is to reach minimizing abrasion and increase the service life and conveniently replaced maintenance effect.

The purpose of this utility model, is to provide a kind of locating structure of model car power transmission shaft, including power transmission shaft and turning sleeve Part, is assembled with a dirt-proof boot and metal sleeve, the ball seat tool of described power transmission shaft front end between described power transmission shaft and steering external member A hollow hole and one in array is had to be in horizontal dented space, this hollow hole and dented space are to connect, and this dirt-proof boot is same When be placed on power transmission shaft and turn to external member on；

The purpose of this utility model, is to provide a kind of locating structure of model car power transmission shaft, the circle of described power transmission shaft front end Ball seat is placed in the inner space turning to external member, and alignment pin penetrates empty to the depression of ball seat after running through the perforation turning to external member Between, metal sleeve is nested with the outer rim at alignment pin two ends, is to arrest limit alignment pin two ends cannot move outward to form metal sleeve；

The purpose of this utility model, is to provide a kind of locating structure of model car power transmission shaft, wherein, penetrates in alignment pin and turns To the ball seat of external member and power transmission shaft and being nested with after the outer rim of alignment pin two ends by metal sleeve, it is able to grease and will again Dirt-proof boot is given to be nested with and is being turned to external member, and oils and fatss so can be protected to be not exposed to dust contamination.

Specific embodiment

First, respect shown in the detailed description please refer to such as Fig. 3, Fig. 4 and Fig. 5: a kind of this case model car power transmission shaft it Locating structure, be power transmission shaft 1 and turn to external member 2 between be to be assembled with a dirt-proof boot 3 and metal sleeve 4, wherein in power transmission shaft 1 The ball seat 11 of front end have one be in upright arrangement hollow hole 111 and be in horizontal dented space 112, make hollow hole 111 and recessed Sunken space 112 is to connect, in power transmission shaft 1 and be arranged with the dirt-proof boot 3 that a quality of rubber materials is made, and metal sleeve 4 be in Empty shape, is provided with an inner space 21, internally space 21 outer rim system is provided with several perforation 211, for alignment pin in turning to external member 2 2a wears.

Be power transmission shaft 1 front end ball seat 11 insert turn to external member 2 inner space 21 after, obtain and worn by an alignment pin 2a Enter to turn to the dented space 112 of the perforation 211 of external member 2 to ball seat 11, afterwards alignment pin 2a two is enclosed within by a metal sleeve 4 End outer rim, after giving oils and fatss o more immediately, obtains and for dirt-proof boot 3 to turn to external member 2 (as Fig. 6 and Fig. 7) to being nested with.
