Embodiment Construction

[0041] Embodiment of the invention

[0042] A first embodiment of the present invention will be described below with reference to the drawings.

[0043] The example is Figure 1 to Figure 5 As shown, the configuration of the variable wheelbase axle of the trailer 12 includes a cylindrical outer axle 16 with a square section supported on the vehicle body 14 of the trailer 12 through a leaf spring 10, which is telescopic and cylindrical and can slide freely in the axial direction but cannot A rectangular cylindrical inner axle 20, which is rotatably supported in the outer axle 16 and at the end protruding from the outer axle 16, freely rotatably supports the wheel 18, is attached to the outer axle 16 to support the aforementioned outer axle 16. A hydraulic cylinder device 22 for axially driving the inner axle 20 , and a locking device 24 for fixing the position of the inner axle 20 relative to the outer axle 16 in the axial direction.

[0044] The leaf spring 10 is constrained...

Abstract

The invention provides variable-tread axles of trailer, in the state of freely advancing and retreating of inside axle relative to outside axle and in the variable-tread axles, realizing stopping the rotation of inside axle and needing no spline to position vehicle at the same time, in addition, realizing enlarging the widening amount of the tread. It has: the outside axle supported on the bodywork by plate springs, the inside axle supporting the wheel, the hydraulic cylinder device driving the inside axle in the axial direction and the locking device fixing the inside axle..

Description

technical field [0001] The invention relates to an improved wheelbase variable axle whose wheelbase can be widened. Background technique [0002] In conventional trailers, such as semi-trailers used for transporting vehicles, the vehicles to be transported pass between the rear wheels of the trailer and are stacked on a springboard for loading. [0003] Thus, the width of a stackable car is limited by the track of the rear wheels of the trailer. Generally, the maximum width of a stackable car is 170 cm. [0004] In this regard, cars with a width of more than 170 cm were transported by themselves in the past. In recent years, these large cars are expected to be transported by trailers. In addition, high-end cars that are passenger cars themselves also tend to have wider widths. [0005] In this regard, as in the past Figure 14 As shown, a scheme that can widen the track of the rear wheels of the trailer is proposed. [0006] That is, the rear axle 1 is composed of an outer...
