Abstract

The utility model relates to a vehicle half-shaft drawing device, for drawing lower half shaft, wherein a disc 1 is engaged with the head of the half shaft, while another side of the disc 1 is arranged with a shaft 4 sheathed with an inertia hammer 3 and a limiting disc 5, the disc 1 is arranged with a plurality of holes radial shaped as bars relative to the mounting bolts of the shaft head. The disc of the drawing device is arranged on the head of the half shaft, which can be taken off via repeated operation of the inertia hammer, with saved time, saved force and high safety.

Description

The automobile axle shaft dismounting apparatus

(1) technical field:

The utility model relates to the automobile axle shaft dismounting apparatus.

(2) background technology:

Propeller-shaft travels by the two-semiaxle driving of back axle symmetry.Because of semifloating axle shaft and fully floating axle have a very big difference textural.So-called semifloating axle shaft has two effects: (1) bearing load; (2) transmit torsion.Semiaxis is to be connected with back axle by a cylinder radial bearing.During the bearing assembling, inside and outside diameter all has a magnitude of interference.Which kind of semiaxis no matter, the resistance of the magnitude of interference is very big when pulling semiaxis, all is to tear open outward with hand or crowbar usually, so not only waste of manpower but also dangerous.

(3) utility model content:

Technical problem to be solved in the utility model is at the problem that exists in the background technology, and the automobile axle shaft dismounting apparatus of a kind of both laborsaving safety is provided.

The invention for solving the technical problem can reach by following technical solution: contain the bolt of installing on semiaxis and the spindle nose on the automobile, the utility model matches with semiaxis spindle nose in the automobile axle disk, the opposite side of this disk is equipped with axle, is with inertia hammer and position-arresting disk on the axle; Have on the disk with the semiaxis spindle nose on the corresponding radially bar shaped of hold-down bolt several holes.

In such scheme, have on the disk with the semiaxis spindle nose on corresponding 4,5 or 6 the bar shaped holes radially of bolt of installing.10 bar shaped radial holes that also can have the bolt installed with the semiaxis spindle nose to be involutory on the disk, wherein the circumferential width in two holes is greater than the width in all the other holes.By the above dismounting apparatus that constitutes, wherein disk is loaded in the automobile axle on the semiaxis spindle nose, overcomes the resistance of the magnitude of interference and take off under the effect repeatedly of inertia hammer, can reach design goal.

The utility model is compared with the above-mentioned background technology can have following beneficial effect: most vehicles of repairing are compact car.The vehicle of producing has very big variation on the semiaxis structure now, and the semiaxis of former compact car mostly is the full-floating structure.Existing majority is the semi-floating structure.So when repairing this position, semiaxis pulls the comparison difficulty.Because multiple semifloating axle shaft is an one with the tire bolt together all.According to this structure, this dismounting apparatus terminal pad is loaded on the semiaxis spindle nose, acts on repeatedly several times and can pull out semiaxis with inertia hammer on the dismounting apparatus.Use this instrument, save the labour, reduce the breaking-up of accessory in repair procedures.

(4) description of drawings:

Accompanying drawing 1 is the utility model erection plan;

Accompanying drawing 2 is Fig. 1 disk 1 planar views.

(5) specific embodiment:

Below in conjunction with the drawings and specific embodiments will the utility model is described in further detail:

Shown in accompanying drawing, contain the bolt of installing on semiaxis and the spindle nose on the automobile, the utility model matches with semiaxis spindle nose in the automobile axle has disk 1, the opposite side of this disk 1 that axle 4 is housed, and is with inertia hammer 3 and position-arresting disk 5 on the axle 4; Have on the disk 1 with the semiaxis spindle nose on the corresponding radially bar shaped of hold-down bolt several holes 7.

In such scheme, can have on the disk 1 with the semiaxis spindle nose on corresponding 4 bar hole (7,9,12,15) or 5 bar hole (7,8,11,13,16) or 6 bar holes (7,8,10,12,14,16) radially radially radially of hold-down bolt; Each radially the circumferential distance of bar hole 7 greater than the diameter of hold-down bolt on the semiaxis spindle nose; The diameter of axle of axle 4 and disk 1 coupling end 2 is greater than the aperture of inertia hammer 3; Axle 4 can be with dish (1,5) and is threaded.Can have on the disk 1 and the semiaxis spindle nose, last hold-down bolt be involutory 10 is bar hole (7 to 16) radially, and the circumferential width of its mesopore (8,16) is greater than the width in all the other holes.Available like this have the dish in 10 holes to replace above-mentioned multiple dish, and the hole of two big circumferential width (8,16) are convenient for assembly, can satisfy the insertion of different number bolts on the spindle nose.Axle 4 afterbodys are handles 6.During work, inertia hammer 3 is reciprocating between coupling end 2 and position-arresting disk 5 under external force, under the effect of force of inertia, can take off and disk 1 bonded assembly semiaxis.
