Horsepower dozer steering clutch in above-mentioned flatrack, described gear friction plate comprises multiple external tooth friction plate and multiple inner blade, and together, external tooth friction plate engages their interfolded with external tooth hub, and inner blade engages with internal tooth hub.
Horsepower dozer steering clutch in above-mentioned flatrack, described ring-type pressing plate is connected by steady brace with annular piston.
Horsepower dozer steering clutch in above-mentioned flatrack, described ring flange and internal tooth hub are tight by locking lock.
Horsepower dozer steering clutch in above-mentioned flatrack, also comprises lock plate in formation, described lock plate is abutted against the side of fitting nut and is connected with ring flange by lock bolt.
Horsepower dozer steering clutch in above-mentioned flatrack, is provided with sealing-ring between described annular piston and internal tooth hub.
The utility model utilizes dish spring and ring-type pressing plate pressing friction sheet, not only avoid the detrimentally affect performance of steering clutch caused owing to pressure is uneven, improve transmission efficiency and the work-ing life of clutch coupling, and reduce the assembly difficulty of clutch coupling, eliminate the accident potential in assembling and maintenance process.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is tradition flatrack dozer steering clutch structural representation;
Fig. 2 is structural representation of the present utility model.
Figure mark as follows: 1, thru-bolt; 2, locking pad; 3, pressure dish; 4, locating sleeve; 5, little spring; 6, big spring; 7, motion-work wheel; 8, follow-up pulley; 9, external tooth friction plate; 10, inner blade; 11, wear ring; 12, piston. 13, locking pin; 14, fitting nut; 15, lock bolt; 16, packing ring; 17, plate is locked; 18, ring flange; 19, dish spring; 20, steady brace; 21, external tooth hub; 22, pressing plate; 23, internal tooth hub; 24, sealing-ring; 25, joint bolt.
