Abstract
The utility model discloses a steering column assembly for a fork truck, which comprises an upper end steering pipe, wherein an upper end steering shaft is installed in the upper end steering pipe; the front end and the rear end of the upper end steering shaft extend out of the front end surface and the rear end surface of the upper end steering pipe respectively; a universal joint is fixed connected to the front end of the upper end steering shaft; and the upper end steering shaft is provided with a conical surface section on which a conductive ring assembly is fixed. The steering column assembly for the fork truck has the advantages of simple structure, low construction cost, and easiness of installation.
Description
Technical field:
The utility model relates to a kind of column assy, relates to the column assy that a kind of fork truck uses in particular.
Background technology:
Fork-truck steering tubing string assembly is to be used for controlling the device that the fork truck direction is rotated, in the time of use and bearing circle be connected.But the column assy that existing fork truck uses, find that in use it has following weak point: 1) Steering gear in use turns to dumb, the generation of catching phenomenon is arranged, this is because of the bearing of installing in the mounting pipe of upper end and the upper end steering shaft matches, so its processing request is than higher; 2) whole steering column assembly structure more complicated, cost are very high.
The utility model content:
The purpose of this utility model is at the deficiencies in the prior art part, and a kind of fork-truck steering tubing string assembly is provided, and it turns to flexibly, and no clamping stagnation is present, and is simple in structure, cheap.
Technology solution of the present utility model is as follows:
Fork-truck steering tubing string assembly, comprise the upper end steering tube, the upper end steering shaft is installed in the steering tube of described upper end, the front/rear end of upper end steering tube is stretched out in this steering shaft rear and front end, upper end, front end captive joint one universal-joint of described upper end steering shaft, at the upper end steering shaft one conical surface section is arranged, be fixed with a conductive ring assembly on this conical surface section.
Described fork-truck steering tubing string assembly, the front end of described upper end steering tube is welded with bearing carrier ring, and this bearing carrier ring internal fixation has one and the bearing that cooperates of upper end steering shaft.
Described fork-truck steering tubing string assembly, described conductive ring assembly is made of conductive ring and overcoat, and described overcoat is fixed on the conductive ring outer circumference surface.
Described fork-truck steering tubing string assembly is equipped with full needle bearing and center cross on the described universal-joint, universal-joint has a female splines that communicates with its front end face.
Described fork-truck steering tubing string assembly, the front end of described upper end steering shaft is bolted and fixed with nut and spring washer.
The utility model beneficial effect is:
1) fork-truck steering tubing string assembly of the present utility model, it is simple in structure, cheap, installation is easy.
2) front end of upper end steering tube is welded with bearing carrier ring, and this bearing carrier ring internal fixation has one and the bearing that cooperates of upper end steering shaft.By bearing carrier ring being welded on the steering tube of upper end, simplified the processing technology of bearing carrier ring, reduced difficulty of processing, guaranteed the bearing of installation after welding and the concentricity of upper end steering shaft, and then it is flexible to have guaranteed that it turns to.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is this novel middle upper end steering shaft structural representation;
Fig. 3 is the structural representation of this novel middle universal-joint;
Fig. 4 is the structural representation of this novel middle conductive ring assembly.
The specific embodiment:
The following stated is preferred embodiment of the present utility model only, is not that scope of the present utility model is limited.
Embodiment, see accompanying drawing 1～4: fork-truck steering tubing string assembly, comprise upper end steering tube 1, upper end steering shaft 2 is installed in the steering tube of described upper end, the front/rear end of upper end steering tube is stretched out in this steering shaft rear and front end, upper end, is convenient to be connected with other part front end captive joint one universal-joint 3 of described upper end steering shaft like this, at the upper end steering shaft one conical surface section 201 is arranged, be fixed with a conductive ring assembly 4 on this conical surface section.
The front end of described upper end steering tube is welded with bearing carrier ring 101, and this bearing carrier ring internal fixation has one and the bearing 102 that cooperates of upper end steering shaft.By adopting the fixing mode of welding, after bearing carrier ring can being processed, welding has reduced difficulty of processing again, has guaranteed the concentricity of bearing and upper end steering shaft.
Described conductive ring assembly 4 is made of conductive ring 401 and overcoat 402, and described overcoat is fixed on the conductive ring outer circumference surface.
Full needle bearing 301 and center cross 302 are installed on the described universal-joint 3, at universal-joint one female splines that communicates with front end face 303 is arranged, on universal-joint, also be provided with one to the lubricated press injecting type lubricating cup 304 of female splines, lubricated by this lubricating cup lubricating oil of can annotating to female splines, reduce noise and wearing and tearing in the use, increase the service life.
The front end of described upper end steering shaft 2 is bolted and fixed with nut 5 and spring washer 6.
