The driving shaft body is characterized in that a locking device, a conical roller bearing and a spiral spring are arranged on the main shaft body in a sleeved mode, a bearing seat with a protruding edge is arranged on the outer ring of the conical roller bearing in a sleeved mode, a limiting device is arranged on the inner side of the bearing seat with the protruding edge and the side surface attached to the outer ring of the conical roller bearing, the locking device and the limiting device are distributed on the two sides of the conical roller bearing, and the locking device and the bearing seat with the protruding edge are connected through a locking device bolt. The driving shaft body of the motor vehicle is high in bearing capacity and high in stability.
Description
Technical field
The present invention relates to a kind of parts of self-propelled vehicle, relate in particular to a kind of driving axis body of self-propelled vehicle.
Background technology
Axle drive shaft is the vitals connecting between change-speed box and drive axle, in the prior art, axis body consists of fixed end Hooke's coupling, axis body and sliding-end Hooke's coupling mostly, even if the heavily loaded axis body of part also can be provided with roller bearing structure, but being generally cylindrical roller bearing is that simple axial compression coordinates with the bearing seat with bead, ubiquity coro bearng very easily produces the shortcoming of play in high-speed operation process, has affected to a certain extent load-carrying capacity and the stability of axis body.
Summary of the invention
Technical matters to be solved by this invention is: provide a kind of stability strong, the driving axis body of the self-propelled vehicle that load-carrying capacity is large.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of driving axis body of self-propelled vehicle, comprise Hooke's coupling, axis body, described Hooke's coupling is connected with described axis body one end, it is characterized in that: on described axis body, be set with latching device, tapered roller bearing and coil spring, described tapered roller bearing outer ring sleeve is equipped with the bearing seat with bead, the side of the described bearing seat with bead inner side, laminating tapered roller bearing outer ring is provided with inhibiting device, described latching device and inhibiting device distribute and are positioned at tapered roller bearing both sides, and described latching device is connected by latching device bolt with the bearing seat with bead.
Described Hooke's coupling one end is connected with the first flanged disc, and described axis body one end is provided with the second flanged disc matching with the first flanged disc, and the first flanged disc is connected by bead bolt with the second flanged disc.
Between described tapered roller bearing and coil spring, be set with position limitation protection body.
Between the left side wall of described latching device and tapered roller bearing outer ring, be provided with oil sealing.
Described Hooke's coupling welds mutually with the first flanged disc.
The described bearing seat with bead inner side is radially extended circular ring type boss and is formed described inhibiting device.
Compared with prior art, the beneficial effect that the present invention has is:
1,, due to latching device of the present invention, lock and coordinate with tapered roller bearing by latching device bolt with the bearing seat of bead, effectively avoided coro bearng in high-speed operation process, very easily to produce the defect of play, so stability is strong.
2, the flange connection due to axis body of the present invention and Hooke's coupling substitutes traditional integral type Forging Technology, install, dismantle, so load-carrying capacity is large.
Accompanying drawing explanation
Fig. 1 is the structural representation of the driving axis body of a kind of self-propelled vehicle of the present invention.
In figure, be labeled as: Hooke's coupling 1, bead nut 2, the first flanged disc 3, the second flanged disc 4, bead bolt 5; latching device 6, latching device bolt 7, tapered roller bearing 8, position limitation protection body 9, axis body 10; oil sealing 11, coil spring 12, with the bearing seat 13 of bead, inhibiting device 14.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
As shown in Figure 1; a kind of driving axis body of self-propelled vehicle; comprise Hooke's coupling 1, axis body 10; described Hooke's coupling 1 is connected with the bead bolt 5 of the second flanged disc 4 by the first flanged disc 3 with axis body 10; on described axis body 10, be set with successively latching device 6, tapered roller bearing 8, position limitation protection body 9 and coil spring 12,9 pairs of tapered roller bearing 8 inner rings of position limitation protection body carry out spacing setting.Described tapered roller bearing 8 outer ring sleeves are equipped with the bearing seat 13 with bead; the right side wall of described bearing seat 13 inner sides with bead, laminating tapered roller bearing 8 outer rings is provided with the axial motion inhibiting device 14 of restriction described tapered roller bearing 8 outer rings, and described inhibiting device 14 can be the structures such as limit baffle ring, spacing jump ring, position limitation protection body, caging bolt and oil sealing.As preferably, the inhibiting device 14 that the present embodiment provides is the described radially extended circular ring type boss in bearing seat 13 inner sides with bead.Described latching device 6, with the bearing seat 13 of bead, by 7 lockings of latching device bolt, coordinate, the axial motion of restriction tapered roller bearing 8 outer rings, eliminates axis body 10 endplays, improves drive shaft assembly stability in use.
Between described latching device 6 and tapered roller bearing 8, be provided with oil sealing 11, latching device 6 carries out axial compression by 7 pairs of oil sealings of latching device bolt 11, play the effect of restriction tapered roller bearing 8 outer ring axial motions, and prevent that impurity from entering in the bearing seat 13 with bead.
Described Hooke's coupling 1 and the first flanged disc 3 sequence welding, described axis body 10 one end are provided with the second flanged disc 4 matching with the first flanged disc 3, the first flanged disc 3 is connected by bead bolt with the second flanged disc 4, has strengthened axis body 10 load-carrying capacitys, makes axis body bring into play better performance.When axis body 10 and Hooke's coupling 1 need to be dismantled, unclamp bead nut 2, just can realize each isolation of components, easy accessibility.
Those of ordinary skill in the art will be appreciated that, above embodiment is only for the present invention is described, and be not used as limitation of the invention, as long as within the scope of connotation of the present invention, to the variation of the above embodiment, modification, all will drop within the scope of claim of the present invention.
