Description
Technical field
The utility model relates to a kind of stop mechanism of a kind of diesel engine high-pressure fuel oil injectionpump.
Background technique
Existing diesel engine of vehicle is mainly manually three kinds of (steel wire cable), pneumatic and electronic parking modes with the parking mode of oil pump, its free state tilts 20 ° to the speed regulator right-hand member under enclosure interior resets the effect of torsion spring or solenoid valve, stop mechanism is inoperative, motor is in starting or normal working, when needs stop by mechanism actions such as backguy or solenoid valves, shutdown handle is that the revolution center of circle pulls to illustrated vehicle stop state position with the shutoff spindle, 20 degree promptly are tilted to the left, the oil pump fuel cut-off, motor quits work, and reaches the parking requirement.
Existing stop mechanism is easy to cause leakage of oil after oil pump uses a period of time, the main positions of leakage of oil is that interference is press-fitted the seal ring position at position and axle two ends, reason is parking linkage structure quick actions such as electromagnet, between housing and the parking lining momentum very the holocaust interference cause loosening and cause leakage of oil, the seal ring at two ends causes that also big shutoff spindle premature wear of frictional force causes that handle sends out heavy and oil leakage phenomenon owing to be two, and the loaded down with trivial details workload of processing technology is big.
The model utility content
Technical problem to be solved in the utility model provides a kind of stop mechanism.
The technological scheme that the utility model solves the problems of the technologies described above is as follows: a kind of stop mechanism, it comprises shutoff spindle and housing, described shutoff spindle is connected on the housing, shutoff spindle is provided with the parking return spring, the parking lining Spielpassung of shutoff spindle one end is pressed in the hole of housing one end, be equipped with sealing configuration between parking lining and housing and the shutoff spindle, the other end of shutoff spindle is provided with the lining that silently stops, the lining Spielpassung of silently stopping is pressed in the hole of the housing the other end, the end face of described shutoff spindle and silently stop and be provided with positioning boss between the lining.
Further, the sealing configuration between parking lining and the shutoff spindle is the oil sealing of band skeleton, and the sealing configuration between parking lining and the housing is the O RunddichtringO.
Further, silently stop and be provided with the O RunddichtringO between lining and the housing.
Further, shutoff spindle is by being arranged on the setting sleeve axially locating of housing inner chamber, and this setting sleeve is arranged between parking lining and the parking return spring.
Further, parking lining and silently stopping is equipped with between lining and the housing adjusts pad and split washer, and described adjustment pad is arranged between housing and the split washer.
Further, the diameter of the parking lining and the lining that silently stops is 14.98mm～14.993mm, and the diameter with the parking lining and the corresponding hole of lining of silently stopping on the housing is 15mm～15.027mm.
The beneficial effects of the utility model are: solve sealing leakage of oil problem effectively; The flywheel moment of shutdown handle tails off, and alleviates the working resistance of shutdown handle; Improved manufacturing efficiency.
Description of drawings
Fig. 1 is the utility model structural representation.
In the accompanying drawing, the list of parts of each label representative is as follows:
1, housing, 2, shutoff spindle, 21, the parking lining, 22, the lining that stops silently, 3, the parking return spring, 4, oil sealing, 5, the O RunddichtringO, 6, setting sleeve, 7, split washer, 8, adjust pad, 9, positioning boss.
Embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.
As shown in Figure 1, a kind of stop mechanism, it comprises shutoff spindle 2 and housing 1, described shutoff spindle 2 is connected on the housing 1, shutoff spindle 2 is provided with parking return spring 3, parking lining 21 Spielpassung of shutoff spindle 2 one ends are pressed in the hole of housing 1 one ends, be equipped with sealing configuration between parking lining 21 and housing 1 and the shutoff spindle 2, the other end of shutoff spindle 2 is provided with the lining 22 that silently stops, lining 22 Spielpassung of silently stopping are pressed in the hole of housing 1 the other end, the end face of described shutoff spindle 2 and silently stop and be provided with positioning boss 9 between the lining 22, this boss 9 plays the axial limiting effect.
Sealing configuration between parking lining 21 and the shutoff spindle 2 is the oil sealing 4 of band skeleton, and the sealing configuration between parking lining 21 and the housing 1 is an O RunddichtringO 5, and sealing effect is better.
Silently stop and be provided with O RunddichtringO 5 between lining 22 and the housing 1.
The diameter of the parking lining 21 and the lining 22 that silently stops is 14.98mm～14.993mm, diameter with the parking lining 21 and the lining 22 corresponding holes of silently stopping on the housing 1 is 15mm～15.027mm (millimeter), and the parking lining 21 and lining 22 Spielpassung of silently stopping are pressed in the corresponding hole, housing 1 two ends.Compared with prior art, increase the diameter of parking lining 21, guaranteed sealing area.
Adopt the structure of the lining 22 that silently stops, shutoff spindle 2 is not exposed, solved the problem of shutoff spindle 2 at this side leakage oil.
Compared with prior art, the side that shutoff spindle 2 is installed the lining 22 that silently stops, shutoff spindle 2 cooperates the seal ring of contact to be reduced to one by 2, the surface friction drag of two rubber seal is reduced to one, the revolution friction torque of handle will significantly reduce, and reduce the working resistance (shutdown handle is installed in a side that is provided with on the shutoff spindle with the parking lining) of shutdown handle.
Because parking lining 21 changes into and housing 1 Spielpassung, just no longer need and be pressed into the logical operation of grinding of two stomidiums behind the parking lining originally like that, improved the up-to-standard rate of production, number of spare parts also is adjusted into 10 types 12 by 14 original of 10 kinds of models, wherein two is standard piece, reduced cost, efficiency of assembling also gets a promotion simultaneously.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
