The shift fork is fixedly installed in shift fork axle by screw.
The front end of the cylinder block is installed, and the end of spring arranges steel ball, steel
Ball under the action of the spring, is withstood in the bulbous recess opened up in shift fork axle.
The cylinder block is bolted on variator bonnet housing.
The shift fork axle is fixedly mounted with piston by nut.
Compared with prior art, this utility model has the advantages that：
This utility model controls conjunction gear and retarder passive tooth by the switching gas of the two-way gas manipulating cylinder of manipulation
The combination and disconnection of wheel, the idling loss of Retarder when can avoid completely normally driving a vehicle, car load fuel economy are good.Compare
Current general flow-disturbing pin, wet clutch and helical spline set technology, the utility model simple structure, technology maturation are reliable
Property it is high, manufacturing cost is low, and suit large area to popularize use.After conjunction gear and retarder driven gear disconnect, retarder turns
Son stops operating, and reduces the mechanical wear of retarder body, extends the replacement cycle of the service life and oil product of oil sealing, greatly
Extend greatly service life and the maintenance period of retarder, and completely no idling loss.
