Abstract
The utility model relates to a modified multichip wet-type hydraulic clutch, which comprises a plurality group of outer friction plates and inner friction plates, and is characterized in that the alloyed steel friction plates are designed into flat shape, the inner and the outer friction plates are separated by lubricating pressure oil, and lubricating oil film is formed between the friction plates, compared with traditional hydraulic clutches, the shift distance of a piston is shortened about half, as the shift distance of the piston is shortened when the clutch is combined, shock noise is reduced, and reliability and service life of the clutch are improved.
Description
Technical field
The utility model relates to a kind of friction engaging and disengaging gear, particularly a kind of had the mechanical transmission of power of connection and cut off the engaging and disengaging gear that machine power is transmitted by what many groups friction plate was formed.
Background technique
At the mechanical industry transmission field, motor → transmission device → working machine is a kind of general connecting mode.Generally all be provided with one or more sets clutches in the transmission device and come the in running order or halted state of Control work machine.Multi-disc wet type hydraulic coupling then is widely used.
Multi-disc wet type hydraulic coupling generally is made up of (outward) friction plate in the alloyed steel of (outward) spline in outer (interior) friction plate of the copper-base powder metallurgy of outer (interior) spline of multi-group and the band.When interior friction plate and outside friction disc are compacted, the frictional force between friction plate with the transmission of power of motor to working machine; When the friction plate group is in relaxed state, interior outside friction disc slide relative, transmission of power is interrupted.
In the prior art, for guarantee clutch from-close reliable smoothness and do not produce " transfer " phenomenon, generally the friction plate with alloy steel material manufactures basin shape and makes it have certain elasticity.After the piston of pressing friction sheet is backed out, rely on the elastic force of basin shape friction plate that the friction plate component is opened.There is following problem in the hydraulic coupling of this structure:
1, the basin shape friction plate manufacturing process complexity of alloy steel material, its elasticity coefficient instability.
2, basin shape friction plate is compared with smooth friction plate, and the working stroke of piston is long, can produce noise because of impacting in the clutch cohesive process.
3, basin shape friction plate is along with the increase of clutch number of times, and to cause friction plate to separate not thorough thereby elasticity can lose efficacy gradually, causes other faults such as clutch " transfer ", heating.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, by the hydraulic coupling conventional construction is carried out improvement and design, and provides a kind of rational in infrastructure, the multi-disc wet type hydraulic coupling that reliability is high.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of modified model multi-disc wet type hydraulic coupling, it is made up of transmission shaft, interior outside friction disc, piston, driving link, driven member, Returnning spring, on transmission shaft, driving link be connected from motor-car, friction plate is connected with piston, lower end at friction plate is provided with Returnning spring, and described friction plate is plate shaped friction plate.Plate shaped friction plate can shorten the displacement distance of piston, has improved the reliability and the working life of clutch.It is to promote piston pressing friction sheet by pressure oil to realize that driving link is connected with driven member, and it is to promote piston by Returnning spring to realize that driving link separates with driven member.
As preferably, described plate shaped friction plate is plate shaped alloyed steel friction plate, friction plate and outside friction disc in plate shaped alloyed steel friction plate is divided into.Plate shaped alloyed steel friction plate has stable elasticity coefficient, and interior friction plate and outside friction disc all are the use that plate shaped alloyed steel friction plate can cooperate more.
As preferably, described transmission shaft is provided with lubricating oil pipeline, and lubricating oil pipeline connects hydraulic chamber, is provided with lubrication pressure oil in the lubricating oil pipeline, when interior friction plate separates with outside friction disc, between interior friction plate and outside friction disc, form lubricant film with lubrication pressure oil.Lubricant film can play a very good protection, and can make the more optimum running of friction plate.
The utility model is simple in structure, and single between manufacturing process, part precision is easier to be controlled, has eliminated other faults such as the friction plate that causes because of basin shape alloyed steel friction plate elastic failure separates not thoroughly, clutch " transfer ", heating.Simultaneously and since clutch in conjunction with the time piston displacement distance shorten, reduced impact noise, improved the working life of clutch.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a friction plate enlarged view of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: as shown in Figure 1 and Figure 2, described modified model multi-disc wet type hydraulic coupling, be respectively arranged with interior friction plate 6 and outside friction disc 5 by two limits that pass on 1, the lower end of piston is provided with Returnning spring 11, driving link 2 and being connected of driven member 10 are to promote piston pressing friction sheet by pressure oil to realize, driving link be separating of driven member to promote piston by Returnning spring to realize.On transmission shaft 1, also be provided with lubricating oil pipeline 9, lubricating oil pipeline 9 be connected hydraulic chamber, be provided with lubrication pressure oil in lubricating oil pipeline 9, lubrication pressure oil can be connected to hydraulic chamber, and described interior friction plate 6 and outside friction disc 5 are plate shaped alloyed steel friction plate.
During use, when the friction plate separation, driving link 2 rotations, driven member 10 is static; When working pressure oil promoted the mobile from left to right pressing friction sheet of piston 4, driven member 10 rotated synchronously with driving link 2, and piston 4 displacement distance sizes depend on that friction plate can separate fully.Returnning spring 11 can make piston 4 reset.The utility model can shorten the displacement distance of piston 4 about half, washes open by lubrication pressure oil when inside and outside friction plate separates and form lubricant film between friction plate, has reduced the noise that impacts, the working life of having improved clutch.
