Abstract
The invention discloses a recyclable self-return middle shaft brake which comprises a housing and a piston mounted in the housing, wherein return springs are arranged at the two sides of the piston in the housing; when the piston is pushed to move by air pressure from entering air, the return springs are compressed; when no air pressure pushes the piston, the return springs push the piston to move downwards. By adding the return springs, the self-return function of the middle shaft brake is reached; multiple layers of friction materials are bonded with the front end of the piston, so that the service life of the middle shaft brake is prolonged, the recycling function is reached, and the maintenance cost is reduced greatly. The piston return problem is solved very well, the recycling function is added, and the use cost and maintenance cost are reduced greatly.
Description
[technical field]
The invention belongs to transmission technology field, relate to a kind of reusable edible self-return intermediate shaft brake.
[background technology]
The most many heavy truck mating asynchronous device change speed gear box have the phenomenon beating tooth shelves are hung in starting when, hold
Easily cause starting gear and the back gear premature breakdown of variator, reduce its service life；Intermediate shaft brake
Effect is the rubbing action by friction pulley, can reduce rapidly power shaft and the rotating speed of one grade of gear of variator
Difference, reaches conveniently to hang the purpose of shelves.Intermediate shaft brake common on market has two shortcomings, and one is to return
Position, two is that service life is short.
[summary of the invention]
It is an object of the invention to the shortcoming overcoming above-mentioned prior art, it is provided that a kind of reusable edible self-return
Intermediate shaft brake.
For reaching above-mentioned purpose, the present invention is achieved by the following technical solutions:
A kind of reusable edible self-return intermediate shaft brake, including housing and the work that is installed in housing
Plug, the both sides of housing inner carrier are provided with return spring, piston is promoted by air inlet air pressure when, return bullet
Spring is compressed, and when piston promotes without air pressure, descent of piston is promoted by return spring.
The present invention is further improved by:
The front end of described piston arranges multiple layer frictional material layer, and the part setting of return spring is installed in piston both sides
There is compound gasket；Housing is stretched out in the front end of piston, a length of H stretched out, by adjusting the thickness of compound gasket,
Ensure that length H that piston nose is stretched out immobilizes.
On the bonding piston of described compound gasket.
Described friction material layer is bonded in the front end of piston.
The cambered surface of depression centered by described friction material layer.
Compared with prior art, the method have the advantages that
The present invention meets the function of brake self-return by increasing return spring, the most bonding in piston nose
Multiple layer frictional material, reaches the function increasing the service life and recycling, and also greatly reduces maintenance simultaneously
Cost.The present invention the most well solves the problem of piston return, increases the function recycled, pole simultaneously
Big reduces use and maintenance cost.
[accompanying drawing explanation]
Fig. 1 is the overall structure schematic diagram of the present invention；
Fig. 2 is the structural representation of inventive piston.
Wherein: 1-housing；2-piston；3-return spring；4-compound gasket；5-friction material layer.
[detailed description of the invention]
Below in conjunction with the accompanying drawings the present invention is described in further detail:
Seeing Fig. 1 and Fig. 2, the present invention includes housing 1 and the piston 2 being installed in housing 1, housing 1
The both sides of inner carrier 2 are provided with return spring 3, piston 2 is promoted by air inlet air pressure when, and return spring
3 are compressed, and when piston 2 promotes without air pressure, return spring 3 is by descending for piston 2 promotion.Before piston 2
Hold bonding multiple layer frictional material layer 5, and the part of piston 2 both sides installation return spring 3 is provided with compound gasket
4, the cambered surface of depression centered by friction material layer 5；Housing 1 is stretched out in the front end of piston 2, a length of H stretched out,
By adjusting the thickness of compound gasket 4, it is ensured that length H that piston 2 front end is stretched out immobilizes.
Return function:
As it is shown in figure 1, return spring 3 is loaded on housing 1, when piston 2 is promoted up by air inlet air pressure
Wait, return spring is compressed, when piston 2 without air pressure promote after, return spring elastic force by descending for piston 2 promotion,
Ensure that piston 2 front end and slip gear sharp separation, reduce the friction between piston 2 front end and slip gear,
Increase its life-span；
Recycling function:
As in figure 2 it is shown, at the front end of piston 2 bonding multiple layer frictional material layer, disappear at ground floor friction material layer
After having consumed, be continuing with the friction material layer of the second layer, by that analogy, can be recycled for multiple times, simultaneously whenever
After friction material layer thickness reduces, highly H changes, so increasing compound gasket 4, is combined by adjustment
The thickness of pad, it is ensured that highly H immobilizes, meanwhile, after friction material layer is all exhausted,
Can be by the way of recovery, its friction material layer the most bonding, this part can be reused, add it
Recycling property, directly lost efficacy with original part compared with, saved maintenance cost greatly.
For new intermediate shaft brake, its self-return effect of return spring, without manual operation, warp
After use after a while, braking effect reduces or lost efficacy, and piston 2 leading portion ground floor friction material weares and teares
Lost efficacy, when thickness reduces, took out a compound gasket, it is ensured that its extension elongation H is constant, thus brake can
To be continuing with, until after multi-disc friction layer material is completely worn out, then from new adhesive friction layer, other parts
Can be continuing with, reach the effect recycled.
Above content is only the technological thought that the present invention is described, it is impossible to limit protection scope of the present invention with this, all
It is the technological thought proposed according to the present invention, any change done on the basis of technical scheme, each fall within this
Within the protection domain of bright claims.
