The oil cylinder inner diameter uses the same-diameter inner pore and the process is simple and the assembly is convenient. The clutch control device has features of high separation, joint control precision and reliability of the clutch.
Description
Technical field
The utility model relates to a kind of control gear, relates to the control gear of the pushing-type hydraulic controlled clutch that a kind of automotive transmission uses in particular.
Background technique
Domestic electric control mechanical type automatic speed variator clutch control mechanism is divided into pushing-type and pull-type two kinds from control structure, is divided into two kinds of Electric Machine Control and hydraulic controls on the control types again.The Electric Machine Control mode is divided into two kinds of feed screw nut or worm and gears again, and what these two kinds of structures all adopted is pushing-type control, because its complicated mechanical driving mechanism makes the precision of transmission and reliability be affected.The specification of Chinese patent CN200620125478.8 and CN200610098178.X discloses a kind of clutch actuating mechanism and hydraulic cylinder assembly of pull-type hydraulic control in detail, but big from its cylinder sleeve difficulty of processing of manufacture view, precision is difficult to guarantee, assembling is inconvenient.And cylinder cavity is stepped, and for the hydraulic controlled clutch of pushing-type, control gear does not also have better solution.
Summary of the invention
The purpose of this utility model is in order to solve complex structure in the prior art, to make difficulty, assembling inconvenience and the not high problem of control accuracy, the clutch control device that a kind of separation of clutch is provided, has used in conjunction with control accuracy and the high automotive transmission of reliability.
The technical solution of the utility model is: be made up of oil cylinder, piston and push rod, it is characterized in that: described cylinder cavity is that secondary piston and back piston are equipped with in the inner chamber two ends with the diameter inner chamber, and the cylinder cavity in forward and backward two-piston neutral position is provided with snap ring; The appropriate location of oil cylinder is provided with reverse endoporus, and non-contact displacement transducer is housed in it.
In order further to realize above-mentioned purpose, said forward and backward piston is provided with the y-type seal ring that cooperates with cylinder cavity, and y-type seal ring places in the groove of forward and backward piston.
The ear end face of described back piston is provided with a globule, and front-end face is provided with an endoporus; The front-end face of described secondary piston is provided with spherical inner hole and links to each other with the bulb of push rod end, and ear end face is provided with cylindrical boss, and magnet ring, plastics spacer ring and spring are housed on the boss, and the other end of spring is contained in the endoporus the inside of back piston.
The utility model is than the advantage of prior art: the oil cylinder internal diameter adopts with the diameter endoporus, is convenient to processing and detection; Change the sealed at both ends form of single piston in the prior art, adopt two independently pistons, the centre is flexible coupling with spring, can guarantee the rigidity of piston like this, is convenient to processing again, more can be flexible coupling by spring, eliminates clutch play effectively; Utilize the elasticity function of spring, more can effectively guarantee the quick separation and the slowly combination of clutch; Adopt non-contact displacement transducer, help improving the control accuracy and the reliability of clutch fluid pressure-controlled.

Embodiment
The utility model is made up of oil cylinder 5, piston and push rod 1, oil cylinder 5 inner chambers are with the diameter inner chamber, and secondary piston 6 and back piston 12 are equipped with in the inner chamber two ends, have annular groove on the cylinder cavity in forward and backward piston 6,12 neutral positions, snap ring 11 is housed in this annular groove, and it is spacing to be used for piston.
The appropriate location of forward and backward piston 6,12 is provided with groove, and groove is provided with the y-type seal ring 7 that cooperates with cylinder cavity.The ear end face of back piston 12 is provided with a globule, and front-end face is provided with an endoporus.The front-end face of secondary piston 6 is arranged to the endoporus of a taper and dribbling shape, link to each other with the bulb of push rod 1 end, ear end face is provided with cylindrical boss, and magnet ring 8, plastics spacer ring 9 and spring 10 are housed on the boss, and the other end of spring 10 is contained in the endoporus the inside of back piston 12.Push rod 1 two ends are set as bulb, the front end bulb links to each other with spherical pore on the clutch separation rocking arm, and the rear end bulb links to each other with the spherical inner hole of secondary piston 6, also is provided with taper on push rod 1, dust-proof cover 3 and dish-shaped back-up ring 4 are housed on the taper, are fixed in the cylinder cavity by back-up ring 2.The appropriate location of oil cylinder 5 is provided with reverse endoporus, and the non-contact displacement transducer 15 of dry-reed or magnetic group formula is housed in it, realizes the accurate control of clutch position with magnet ring 8 actings in conjunction on the piston 6.Non-contact displacement transducer 15 end faces adopt O-ring seals 13 sealings reaching the effect of dustproof and waterproof, and fixing by two screws 14.
Its working principle is the push rod 1 that connects the clutch separation rocking arm, under the effect of clutch diaphragm spring, promotes secondary piston 6 to the right, and pressure spring 10 drives back piston 12 again and moves right, and clutch is in the state of normal combination.When hydraulic oil by advance/after oil outlet 16 entered oil cylinder, hydraulic oil acted on back piston 12 rear ends, and back piston 12 is moved to the left, and under the double action of hydraulic oil and spring 10, promoted secondary piston 6, push rod 1 is moved to the left, and realizes the quick separation of clutch.When hydraulic oil by advance/when oil outlet 16 is discharged oil cylinders, under the return effect of clutch diaphragm spring, move right by push rod 1 drive secondary piston 6, spring 10, back piston 12, under the double action of hydraulic oil and pressure spring 10, realize the slow combination of clutch.
