Abstract
The utility model discloses a connecting and combining structure of a rear axle housing trivet and a vehicle frame of an electric-transmission mining dump vehicle. The connecting and combining structure comprises a hollow hinge pin, a spacing ring, a sealing ring, an oscillating bearing, a bearing support, an end cover flange, a flat disc, a bolt, a vehicle frame thrust frame and the rear axle housing trivet. The bearing support is fixed on the rear axle housing trivet. The oscillating bearing is installed on the bearing support. The end cover flange is installed on the bearing support and fixed on the bearing support through the flat disc and the bolt. The hollow hinge pin is arranged in the oscillating bearing. Two ends of the oscillating bearing are fixed on the vehicle frame thrust frame. The vehicle frame thrust frame is connected with the rear axle housing trivet. The spacing ring and the sealing ring are arranged between the bearing support and the vehicle frame thrust frame. The connecting and combining structure of the rear axle housing trivet and the vehicle frame of the electric-transmission mining dump vehicle has the advantages of being simple in structure, easy to implement and capable of prolonging the service life of the oscillating bearing, preventing the rear axle housing trivet from fractures caused by free rotation generated between the rear axle housing trivet and the vehicle frame, and providing stable and reliable support for the electric-transmission dump vehicle.
Description
Technical field
The utility model relates to the unitized construction that is connected of the moving quarry tipper rear-axle casing tripod of a kind of fax and vehicle frame, belongs to the connection structure field.
Background technology
On electronic quarry tipper, the rear-axle casing tripod is one of key structure in the dumping car assembly with the unitized construction that is connected of vehicle frame, and whether the size of its intensity and sealing well will directly influence the useful service life of dumping car; The road surface operating mode badly can make the rear-axle casing tripod bear bigger twist moment, can make the fracture of rear-axle casing tripod when intensity is not all right, and closed type is bad will directly to influence the service life of oscillating bearing.Therefore, tripod and vehicle frame is connected unitized construction and must has enough intensity and good sealing property.
Be connected by oscillating bearing, bearing pin mode between rear-axle casing tripod on the existing quarry tipper and the vehicle frame, and be used for oscillating bearing on the large-tonnage quarry tipper because the excessive sealing arrangement that often do not carry, owing to directly exposing, it in bad working environment, does not have dustproof effect even perhaps have the oscillating bearing of hermetically-sealed construction yet, thereby shortened the service life of oscillating bearing, generation is small between causing rear-axle casing and vehicle frame being connected freely rotates, and finally causes the tripod fracture.
Summary of the invention
Problem at above-mentioned prior art existence, the utility model provides the be connected unitized construction of the moving quarry tipper rear-axle casing tripod of a kind of fax with vehicle frame, it is simple in structure, be easy to realize, can prolong the service life of oscillating bearing, avoid tripod because of and vehicle frame between produce freely to rotate and rupture, move dumping car for fax reliable and stable support be provided.
To achieve these goals, the technical solution adopted in the utility model is: the unitized construction that is connected of the moving quarry tipper rear-axle casing tripod of a kind of fax and vehicle frame, comprise hollow bearing pin, spacer ring, seal ring, oscillating bearing, bearing brackett, the end cap flange, plate, bolt, vehicle frame thrust frame and rear-axle casing tripod, described bearing brackett is fixed on the rear-axle casing tripod, oscillating bearing is installed on the bearing brackett, load onto the end cap flange, and by plate and bolt the end cap flange is fixed on the bearing brackett, be provided with hollow bearing pin in the oscillating bearing, the two ends of hollow bearing pin are fixed on the vehicle frame thrust frame, the vehicle frame thrust frame is connected with the rear-axle casing tripod, is provided with spacer ring and seal ring between bearing brackett and the vehicle frame thrust frame.
The beneficial effects of the utility model are: by on hollow bearing pin, the oscillating bearing two ends are provided with spacer ring and seal ring, seal ring can play dustproof effect, thereby the service life of the oscillating bearing that improves, in conjunction with spacer ring, can guarantee can freely not rotate and end float misalignment between vehicle frame thrust frame and the rear-axle casing tripod, the situation of avoiding rupturing because of rotation takes place, for the moving dumping car of fax provides reliable and stable support; Simple in structure, be easy to realize.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, hollow bearing pin, 2, spacer ring, 3, seal ring, 4, oscillating bearing, 5, bearing brackett, 6, the end cap flange, 7, plate, 8, bolt, 9, the vehicle frame thrust frame, 10, the rear-axle casing tripod.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the unitized construction that is connected of the moving quarry tipper rear-axle casing tripod of a kind of fax and vehicle frame, comprise hollow bearing pin 1, spacer ring 2, seal ring 3, oscillating bearing 4, bearing brackett 5, end cap flange 6, plate 7, bolt 8, vehicle frame thrust frame 9 and rear-axle casing tripod 10, described bearing brackett 5 is fixed on the rear-axle casing tripod 10, oscillating bearing 4 is installed on the bearing brackett 5, load onto end cap flange 6, and by plate 7 and bolt 8 end cap flange 6 is fixed on the bearing brackett 5, be provided with hollow bearing pin 1 in the oscillating bearing 4, the two ends of hollow bearing pin 1 are fixed on the vehicle frame thrust frame 9, vehicle frame thrust frame 9 is connected with rear-axle casing tripod 10, is provided with spacer ring 2 and seal ring 3 between bearing brackett 5 and the vehicle frame thrust frame 9.
During concrete the connection, can earlier oscillating bearing 4 be installed on the bearing brackett 5 that is fixed on the rear-axle casing tripod 10, end cap flange 6 fixing joint bearings 4 are installed again, and with plate 7, bolt 8 end cap flange 6 are fixed on the bearing brackett 5; Again hollow bearing pin 1 is inserted in the oscillating bearing 4, and load onto spacer ring 2 and seal ring 3 successively at the two ends of hollow bearing pin 1, the rear-axle casing tripod that will have hollow bearing pin 1 at last is installed on the vehicle frame thrust frame 9, just vehicle frame thrust frame 9 and rear-axle casing tripod 10 can have been linked together.Easy installation and removal, seal ring is equipped with at oscillating bearing 4 two ends, can play dustproof effect, thereby the service life of the oscillating bearing that improves, add spacer ring 2 simultaneously, guarantee can freely not rotate and end float misalignment between vehicle frame thrust frame 9 and the rear-axle casing tripod 10, the situation of avoiding rupturing because of rotation takes place, for the moving dumping car of fax provides reliable and stable support.
