Description
(1) technical field:
The utility model relates to a kind of clutch, hydraulic pressure reverse clutch particularly, and the utility model also relates to the multifunctional tractor that uses this clutch.
(2) background technique:
Existing hydraulic pressure reverse clutch generally all aims at large-scale Machinery Design, so complex structure, cost is higher, and in, small engineering machinery, as in, in the microtractor (power is 15 to 80 horsepowers tractor), generally all be to use mechanical clutch, and no matter be normal engagement type, still the unusual mechanical clutch of engagement type, at engage a gear, when gear shift and commutation, all must step on main clutch earlier, cut off engine power, realize engage a gear by gearbox again, gear shift and commutation, therefore, the mechanical clutch effort that operates, loaded down with trivial details, work efficiency is low, and wearing and tearing are very fast, working life is short.For this reason; the applicant has designed a kind of hydraulic pressure reverse clutch that is fit to medium and small engineering machinery and the use of medium and small tractor farm machinery such as (comprising crawler and wheeled); this hydraulic pressure reverse clutch not only has the function of ordinary clutch; also has commutation function; the machine of this hydraulic coupling is installed, no matter is starting or shuts down, advance or fall back; as long as make it just can realize that in corresponding position it is free and relaxed to operate with the handling reversing rotary valve.In addition; because this hydraulic pressure reverse clutch has commutation function; therefore, be fitted with the tractor of hydraulic pressure reverse clutch, the reverse gear mechanism of its transmission case and corresponding gear all can be cancelled; this has just simplified the project organization of transmission case; when operating machines, no matter be to switch to by advancing to retreat, still advance by retreating to switch to; all need not shut down gear shift, but easily and apace realize by the hydraulic pressure reverse clutch.Existing hydraulic coupling has lot of superiority with respect to mechanical clutch, but also has following defective:
1) oil circuit complexity, interface is many, and manufacturability is poor:
Existing hydraulic pressure reverse clutch working oil trend is: from handling rotary valve, pipeline, transit joint 10 enter in the clutch housing 11, and------flow cover 9---the flow pipe 17 in the driving shaft 1---is in the clutch operating cylinder 2 for engage a gear oil pipe (engage a gear oil circuit 12).
1. wherein the engage a gear oil pipe is oversize, and its two ends are connected with interface respectively with between transit joint 10 and the flow cover 9, and this interface is difficult to adjust and installation when assembling, jointing seal ring easy oil leakage again during work.
2. in order when assembling, to make flow cover 9 that certain degree of regulation can be arranged, so that align with engage a gear oil pipe port, the flow cover must be fitted on the clutch front cover in the mode of floating, this structure makes and have bigger wearing and tearing between flow cover 9 and the driving shaft 1 forever when work, thereby causes seal failure between driving shaft 1 and the flow cover 9.
3. the oil duct of joining of driving shaft 1 is provided with flow pipe 17, join oil duct and wherein between the flow pipe 17 with O RunddichtringO 13 sealing, this structure processing and assembling are all difficult, easily shear O RunddichtringO 13 during assembling, make it to lose efficacy, cause system's leakage of oil, make the working pressure deficiency or do not have working pressure machine cisco unity malfunction at all.
2) cylinder body 2 is two elements that separate with driving shaft 1, therefore:
1. quality of fit is poor between cylinder body 2 and the piston 6.
There is friction when 2. working between cylinder body 2 and the piston 6 always.
3. rely on the sealing of O RunddichtringO 7 unreliable between cylinder body 2 and the piston.
3) back clutch gear 3 relies on spline assembling transmission with driven shaft 4, the assembling link is many, complex structure, poor work stability, and this structure makes the spacing that 10mm is only arranged between two running in bearingss 5 of driven shaft 4, causes the poor stability of driving shaft 1 and driven shaft 4 high speed rotary motions.
4) the O RunddichtringO between driving shaft 1 and the piston 6 makes the frictional force between driving shaft 1 and the piston 6 too big, therefore required return spring 8 more (generally needing 30 little springs), so complex structure, and the assembling link is many.
5) rely on two pin one sides to be located by connecting between clutch housing and the motor body, make that the concentricity between clutch driving shaft and the engine output shaft is poor, the stationarity of motion, poor reliability, working life is short.
