Abstract
The utility model relates to a drive device of a front drive axle of a tractor. The drive device of the front drive axle of the tractor comprises a transfer case, transmission shafts and an overrunning clutch, the overrunning clutch is arranged between the transfer case and the front drive axle, and the transfer case, the overrunning clutch and the front drive axle are connected through the transmission shafts. The drive device of the front drive axle of the tractor can also use an electric-hydraulic control clutch, the electric-hydraulic control clutch is arranged between the transfer case and the front drive axle, the transfer case, the electric-hydraulic control clutch and the front drive axle are connected through the transmission shafts, and the control unit of the electric-hydraulic control clutch is respectively connected with a front axle input shaft rotating speed sensor and a rear axle input shaft rotating speed sensor. According to the drive device of the front drive axle of the tractor, the overrunning clutch or the electric-hydraulic clutch is arranged between the transfer case and the front drive axle, so that the transfer case only can drive the front drive axle through the transfer case transmission shaft when the tractor goes forward and rear wheels slip by a certain degree, when the rear wheels do not slip or the slip rate is low, even if the transfer case is located at a four-wheel drive state, the transfer case does not drive the front drive axle, and accordingly the energy consumption is lowered.
Description
Technical field
The utility model relates to a kind of actuating device of front drive axle of tractor.
Background technology
The auxiliary gear box of existing agricultural traction engine and front driving axle are directly by transmission shaft connection for transmission, front and back drive wheel diameter differs large and adopts front-wheel steering, conventionally compared with trailing wheel linear velocity slightly hurry up, there is parasitic horsepower in driving system to front-wheel linear velocity in the time of four wheel drive.
Utility model content
Technical problem to be solved in the utility model is: a kind of actuating device of front drive axle of tractor is provided, in the time of four wheel drive, avoids unnecessary front and back wheel parasitic horsepower, reduce energy consumption.
The utility model solves the technical scheme that its technical matters adopts: a kind of actuating device of front drive axle of tractor, comprise auxiliary gear box, transmission shaft and overriding clutch, overriding clutch is arranged between auxiliary gear box and front driving axle, between auxiliary gear box and overriding clutch, connect by transmission shaft, between overriding clutch and front driving axle, be connected by transmission shaft.
Auxiliary gear box only at trailing wheel in the time advancing middle skidding, by the automatic engagement of overriding clutch, automatically drive front driving axle, non-slip once trailing wheel, by the automatic centrifugation of overriding clutch, auxiliary gear box no longer drives front driving axle, and front driving axle is in servo-actuated state.
A kind of actuating device of front drive axle of tractor, comprise auxiliary gear box, transmission shaft and electric hydraulic control clutch, propons input shaft rotating speed sensor and back axle input shaft rotating speed sensor, electricity hydraulic control clutch is arranged between auxiliary gear box and front driving axle, between auxiliary gear box and electric hydraulic control clutch, connect by transmission shaft, between electricity hydraulic control clutch and front driving axle, be connected by transmission shaft, the control unit of electric hydraulic control clutch is connected with propons input shaft rotating speed sensor and back axle input shaft rotating speed sensor respectively.
The control unit of electricity hydraulic control clutch is according to front and back wheel speed discrepancy, judge whether trailing wheel skids, and in the time that rear wheels slip rate acquires a certain degree, control electric hydraulic control clutch engagement, auxiliary gear box drives front driving axle,, controls electric hydraulic control clutch and separates lower than setting value once rear wheels slip rate, make auxiliary gear box no longer drive front driving axle, front driving axle is in servo-actuated state.
The beneficial effects of the utility model are: by overriding clutch or electric hydraulic control clutch are set between auxiliary gear box and front driving axle, make auxiliary gear box only in the time advancing and rear wheels slip just drive front driving axle by auxiliary gear box transmission shaft to a certain extent time, do not skid or when the rate of skidding is lower at trailing wheel, even if auxiliary gear box is in four wheel drive state, auxiliary gear box can not drive front driving axle yet, avoid unnecessary front and back wheel parasitic horsepower, reduced energy consumption.
