Abstract
The utility model discloses a double-freedom-degree hinge disk, and belongs to the technical field of hinge disks. The technical problem to be solved is how to provide the double-freedom-degree hinge disk which can realize the turning function and can also buffer lengthwise torque. According to the technical scheme, the double-freedom-degree hinge disk comprises a front hinge frame, a hinge pin, a rear hinge frame, a turning oil cylinder locating pin and a turning oil cylinder seat. The rear hinge frame is of a Y-shaped structure with the front end forked, a first ball bearing, a second ball bearing, a locating nut and a bearing end cover are sequentially arranged on the circumference of the rear end of the rear hinge frame in a sleeved mode, the outer portion of the first ball bearing and the outer portion of the second ball bearing are sleeved with a bearing locating seat, an annular boss is arranged on the inner circumference of the bearing locating seat to separate the first ball bearing from the second ball bearing, and the bearing end cover is fixed on an end face of the bearing locating seat though a bolt. The double-freedom-degree hinge disk realizes the turning freedom degree, also buffers the lengthwise torque of the front hinge frame and the rear hinge frame, and avoids deformation caused by lengthwise torque.
Description
Technical field
A kind of double freedom hinged disk of the utility model, belong to the hinged disk technical field.
Background technology
Mine car on domestic market hinged disk used adopts welded type single degree of freedom hinged disk mostly, and this kind articulated disk structure is simple, under smooth road conditions, on not impact of locomotive.But when road conditions are poor, have vertical moment of torsion between the body cradle of front and back, at this moment the single degree of freedom hinged disk can't cushion vertical moment of torsion, and therefore the front and back body cradle can be out of shape, and this distortion is difficult to recover and keep in repair.
The utility model content
The utility model overcomes the deficiency that prior art exists, and technical matters to be solved is to provide a kind of double freedom hinged disk that can realize turning function, can cushion again vertical moment of torsion.
in order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of double freedom hinged disk, comprise front body cradle, swivel pin, rear body cradle, steering cylinder locating dowel pin and steering cylinder seat, rear body cradle is the Y-shaped structure of front end bifurcated, hinged by two swivel pins between the front end of front body cradle and rear body cradle, the both sides of rear body cradle are provided with the steering cylinder seat, the steering cylinder locating dowel pin is installed on the steering cylinder seat, be set with successively the first ball bearing of main shaft on the periphery of rear body cradle rear end, the second ball bearing of main shaft, setscrew nut and roller bearing end cap, the bearing positioning seat is sleeved on the outside of the first ball bearing of main shaft and the second ball bearing of main shaft, and being provided with annular boss on the inner headed face of bearing positioning seat separates the first ball bearing of main shaft and the second ball bearing of main shaft, roller bearing end cap is bolted on the end face of bearing positioning seat.
The inside of described rear body cradle has for the hole that transmission shaft is installed, and the two ends in hole are provided with two bearing seats.
The rear end of described rear body cradle has two lubricated hydraulic fluid ports.
Described front body cradle and rear body cradle are cast structure.
The beneficial effect that the utility model compared with the existing technology has is.
1, the utility model had both been realized the turning degree of freedom, and before and after having cushioned again, vertical moment of torsion of body cradle, avoided the distortion that is caused by vertical moment of torsion, thereby increased the service life of hinged disk.
2, front body cradle of the present utility model and rear body cradle are cast structure, have reduced welding deformation, have simplified processing technology, can bear larger varying stress.
3, transmission shaft is arranged in the hole of rear body cradle, has reduced transmission shaft rocking when high-speed operation, the stationarity while having increased the transmission shaft running.
