Abstract:
The present invention provides a power gear-shifting transmission and an engineering machinery. The power gear-shifting transmission comprises a clutch shaft assembly (1). The clutch shaft assembly (1) comprises a clutch shaft (11), a housing gear (12) arranged on the clutch shaft (11), a clutch disc (13) arranged within the housing gear (12), and a gear-shifting piston (14) arranged at one end of the clutch disc (13). The gear-shifting piston (14) is pushed by a clear hydraulic medium introduced via a fluid supply passage (3); the clean hydraulic medium is supplied by a hydraulic system (2). The engineering machinery comprises the power gear-shifting transmission.
