However, in the instructions, each upper axle support part of the axle support parts is connected to the rear frame by welding, which is prone to failure and expensive
[0006] Moreover, in the prior art, each upper axle support member of the axle support member is welded to the rear frame, so it is difficult to ensure that the paired center pin sockets are positioned concentrically with each other
In order to improve the concentricity of the center pin socket of the welded upper shaft support part, it is necessary to set a bush made of rubber in the center pin socket, because the rubber is relatively expensive, so the cost of the shaft support structure in the prior art just increased
[0007] Moreover, in the existing structures disclosed in the above-mentioned documents, the strength of the bonding point between the upper shaft support member and the rear frame is insufficient.
That is to say, it is difficult to ensure that the existing shaft support structure has a high enough strength

Embodiment Construction
[0019] Hereinafter, an axle support structure of an industrial vehicle according to a preferred embodiment of the present invention will be described with reference to FIGS. 1 to 4 . The following description will use a forklift as an example of an industrial vehicle.
[0020] FIG. 1 is a side view of a forklift 1 according to the preferred embodiment of the present invention. As shown in FIG. 1, the forklift 1 includes a counterweight 21 at the rear of the vehicle. The counterweight 21 is made of a cast iron block, the external shape of which is adapted to form the rear of the vehicle, with grooves to accommodate the rear wheel 2, a rear axle beam 3 to be described in detail later and shown in Figures 2 and 3 Heavy-represented shaft support components. It should be noted that FIG. 2 is a partially enlarged schematic view of a cross section of the rear axle beam along the longitudinal direction at the central portion in the region II surrounded by the dotted frame in FIG. 1 ...

An axle supporting structure for supporting an axle beam for an industrial vehicle includes a center pin, a pair of axle supporting units and a counterweight. The center pin protrudes from the axle beam. Each axle supporting unit has formed therethrough an insertion hole in which the center pin is inserted. The axle supporting unit has an upper axle supporting member and a lower axle supporting member which is detachably connected to the upper axle supporting member. The pair of axle supporting units is spaced from each other in a traveling direction of the vehicle. The center pin is rotatably supported between the pair of axle supporting units. The upper axle supporting members of the axle supporting units are cast in the counterweight.
Description
technical field [0001] The present invention relates to an axle support structure for an industrial vehicle which is rotatably supported on a center pin of an axle beam located between a pair of axle support members which are mutually in the direction of travel of the industrial vehicle Spaced arrangement, the present invention also relates to an industrial vehicle having the structure. Background technique [0002] In a balance forklift, the axle beam is usually supported in such a way that the beam can rotate or swing around the center pin in a rolling surface, so as to improve the stability of the vehicle when driving on rough roads. The center pin of the rear axle beam is inserted into the hole on the pair of axle support parts, and the pair of axle support parts are spaced apart from each other and located on the front and rear sides of the rear axle beam respectively, so that the rear axle beam can be supported by the pair of axle support parts. rotatably supported. ...
