Description
Technical field
The invention belongs to automobile technical field, be specifically related to a kind of provision for disengagement of lining.
Background technology
Shock absorbing bushing, as the conventional elastic component connecting vehicle control arm and the parts such as subframe or vehicle body, has the impact alleviated road injustice, vehicle acceleration and braking and cause, ensures the characteristic of occupant's comfortableness, control stability.As shown in Figure 1 be the structure of common lining, it comprises axle core and overlaps, and the metal inner pipe 1 that caliber increases successively, rubber tube 2 and metal outer pipe 3, rubber tube 2 and metal inner pipe 1, metal outer pipe 3 is sulfided into one, during use, lining entirety is pressed in the pore as the base of control arm body etc., and the metal outer pipe 3 of lining and pore interference fit, the connection of control arm and the parts such as subframe or vehicle body can be realized like this through the metal inner pipe 2 of lining by connecting rod, when vehicle travels, rubber tube 2 can produce the vibrations of radial elastic deformation opposing from metal inner pipe 1 or control arm body, to make vehicle operating more steady, actually add man-hour, the axial length of described metal inner pipe 1 is greater than the axial length of metal outer pipe 3, to facilitate the layout of connecting rod.
Because lining is in repeated deformation state in vehicle operating, rubber tube 2 is very easily destroyed, and then cause the cushioning ability of lining greatly to decline, therefore need in time the lining of damage to be split out in the pore of base to be changed.At present, if corporate boss adopts violence hammering, baked wheaten cake rubber tube 2 or Special purpose pressing machine to dismantle lining, wherein violence hammering and burn rubber tube 2 can have expendable infringement to the state of control arm undoubtedly, and configure dedicated press not only cost is high, and portability and popularization poor.
Summary of the invention
The object of this invention is to provide a kind of cost and the provision for disengagement of lining easy to use.
For achieving the above object, the technical solution used in the present invention is: a kind of provision for disengagement of lining, lining is fixedly installed in base, it is characterized in that: comprise supporting seat, supporting seat is provided with recess with the end face within the scope of the contact area of base, the diameter of this recess coincide with the external diameter of lining and both positions are corresponding, other one end that base deviates from supporting seat is provided with depression bar, the external diameter of depression bar is less than the pore diameter of base and the end of the rod end of depression bar and lining leans, and actuating unit drives supporting seat and depression bar to move in opposite directions.
The beneficial effect adopting technique scheme to produce is: during use, by one end corresponding layout of one end of base with the recess place of supporting seat, other one end layout corresponding with the rod end of depression bar of base, and guarantee that the same core of supporting seat and lining is arranged, then drive depression bar and supporting seat to form by actuating unit to move in opposite directions, so can effectively lining be taken apart in the pore of base.

Detailed description of the invention
A kind of provision for disengagement of lining, shown in composition graphs 2-5, lining A is fixedly installed in base B, it comprises supporting seat 10, supporting seat 10 is provided with recess 11 with the end face within the scope of the contact area of base B, the diameter of this recess 11 coincide with the external diameter of lining A and both positions are corresponding, other one end that base B deviates from supporting seat 10 is provided with depression bar 20, the external diameter of depression bar 20 is less than the pore diameter of base B and the end of the rod end of depression bar 20 and lining A leans, and actuating unit drives supporting seat 10 and depression bar 20 to move in opposite directions.During use, the lining A damaged in pore for press-in base B, can by one end corresponding layout of one end of base B with recess 11 place of supporting seat 10, other one end layout corresponding with the rod end of depression bar 20 of base B, and guarantee that supporting seat 10 is arranged with the same core of lining A, then drive depression bar 20 to promote lining A and move by actuating unit, namely depression bar 20 and supporting seat 10 form and move in opposite directions, so can effectively be taken apart in the pore of base B by lining A.Structure of the present invention is simple, and processing cost is low, and easy to use, effectively can realize the dismounting of lining A on the parts such as automobile control arm.
As further preferred version: as shown in Figure 2-5, supporting seat 10 and depression bar 20 are pipe fitting and arrange with core with the lining A on base B, metal outer pipe A on the pipe end of depression bar 20 and lining A
3pipe end lean.The depression bar 20 of tubulose is selected not only to save material cost, and the metal inner pipe A of lining A due to prior art routine
1axial length be greater than metal outer pipe A
3axial length, to facilitate the layout of the connecting rod for parts such as connection control arm and subframes, therefore select the pipe end of the depression bar 20 of tubulose to be directly pressed on metal outer pipe A on lining A
3pipe end, can guarantee that lining A can move back completely in the pore of base B and unload out.Concrete, outside dimension metal outer pipe A on lining A of depression bar 20
3internal diameter and external diameter between, to guarantee that the active force of depression bar 20 all acts on metal outer pipe A
3on.
Concrete scheme is, as in Figure 3-5, described actuating unit is jack 30.In the automobile of general car owner and auto repair shop is all configured with jack 30, therefore selects jack 30 to provide power for the movement in opposite directions of supporting seat 10 and depression bar 20, very convenient, and popularization is high.The lining A that what Fig. 3-5 showed respectively is on automobile control arm C is to be removed, unloading process and entirely disassembled three state diagrams, and for the ease of understanding the position relationship of lining A and control arm C, in Fig. 3-5, only show the half of sectional view in right side of lining A, depression bar 20 and supporting seat 10.In addition, because jack 30 provides lifting force upwards, therefore need to arrange a framework 40 as shown in Figure 3 during actual use, supporting seat is arranged on the base of framework 40, the top of jack 30 is subject to the top constraint of framework 40, be subject to the effect of contraction of framework 40 during such jack 30 action, thus supporting seat 10 and depression bar 20 formed move in opposite directions, and then realize the dismounting of lining A.Preferably, the axial length of depression bar 20 is greater than the length of action of lining A and base B, to guarantee in a state of use, the end that when lining A moves back by depression bar 20 completely from the pore of base B, depression bar 20 compresses lining A is still positioned at outside the pore of base B, and then facilitates the top 31 of jack 30 to arrange.As similar technique effect, concrete, as in Figure 3-5, the axial length of depression bar 20 is greater than the metal outer pipe A of lining A
3with metal inner pipe A
1the face height being positioned at same side is poor.
