Abstract
The utility model relates to a driving axle vent pipe structure of a shovel loader which is characterized in that the vent pipe is composed of a vent pipe body, a connecting nut and a pipe joint; Adopting the tapered clamping-nesting type structure, the utility model is dispensed with the need to rotate the vent pipe body during installation and dismantling, thus avoiding the difficulties in installation and maintenance from the interference of the rotary radius and the frame lateral plate due to rotation; meanwhile, the direction of the bending end of the vent pipe body can be selected freely.
Description
Technical field
The utility model relates to a kind of loader drive axle bite type permeability cell structure, can be used for loader drive axle assembly, is specifically designed to balance drive axle inner and outer air pressure, freely selectes the dismounting angle of permeability cell, maintenance convenient for assembly.Belong to the loader technical field.
Background technology
Wheel loader is a kind of Engineering Work machine that shovels the material shipment, be widely used in the infrastructures such as city, traffic, water conservancy, be called as " multi-functional mechanical ", permeability cell is positioned at loader drive axle axle housing top, its major function is the balance bridge inner and outer air pressure, be made up of ventilative body, nut etc., for rainproof and dustproof, ventilative body is designed to curved shape.As shown in Figure 1, 2, be former loader drive axle permeability cell structural representation, form by six square nuts 1, permeability cell 2, permeability cell 2 is contained in earlier on the drive axle axle housing 3, is installed on the vehicle frame Side plate 4 of loader with drive axle axle housing 3, because permeability cell 2 is very approaching with vehicle frame Side plate 4 again, if need maintenance, the radius of gyration of permeability cell 2 just is easy to be subjected to vehicle frame Side plate 4 to interfere, and can't disassemble, and avenged a grievance by the user.
Summary of the invention
The purpose of this utility model provides a kind of loader drive axle bite type permeability cell structure that makes things convenient for installing/dismounting.
For realizing above purpose, the technical solution of the utility model provides a kind of loader drive axle bite type permeability cell structure, it is characterized in that, is made up of ventilative body, attaching nut and union, and ventilative body is connected with union by the attaching nut.
Described ventilative body one end becomes bending, plays rainproof anti-gray effect, and it is horn-like that the other end becomes, and tapering is 70-80 °; Described attaching nut's one end becomes inner cone, and tapering is 70 °-80 °, places outside the ventilative body horn mouth, and the other end is an internal thread; Described union one end is 70 ° of-80 ° of outer cones, external screw thread thereafter and attaching nut's screw-internal thread fit, and the other end is that external screw thread is connected with the drive axle axle housing.
The utility model adopts bite type taper fit structure with union, attaching nut, ventilative body three, by the turn attaching nut, make three's the fastening or separation of tapering, when the dismounting permeability cell, only need swivel joint and attaching nut just permeability cell can be installed or removed, do not cause radius of gyration and the collision of vehicle frame Side plate and do not need to rotate ventilative body, the bending end of ventilative body is towards can freely selecting maintenance convenient for assembly simultaneously.
The advantage of the utility model structure is: when the dismounting permeability cell, only need swivel joint and attaching nut's outer six sides just permeability cell can be installed or removed, do not cause radius of gyration and vehicle frame Side plate to interfere and do not need to rotate ventilative body, the bending end of ventilative body is towards can freely selecting simultaneously.
The utility model has the advantages that and make things convenient for installing/dismounting.
Description of drawings
Fig. 1,2 former loader drive axle permeability cell structural representations;
Fig. 3 is the utility model loader drive axle bite type permeability cell structural representation;
Fig. 4 is the utility model loader drive axle bite type permeability cell vertical view.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
Shown in Fig. 3,4, be the utility model loader drive axle bite type permeability cell structural representation, described loader drive axle permeability cell is made up of ventilative body 5, attaching nut 6 and union 7.
During installation, screw on drive axle axle housing 3 with the external screw thread of instrument with union 7 one ends earlier, the body 5 bending ends of will breathing freely then place needed orientation, screw attaching nut 6 with instrument at last.
During dismounting, attaching nut 6 is unscrewed earlier, and then union 7 unscrewed from drive axle axle housing 3 take off with instrument.
Since do not need to rotate ventilative body 5, the problem of avoiding ventilative body 5 radius of gyration and vehicle frame Side plate 4 to interfere, and the curved end of ventilative body 5 is towards can freely selecting simultaneously.
The utility model permeability cell structure is except that being used for the loader drive axle, also applicable to similar places such as other engineering machinery, building machinery, load-carrying vehicles.
