WO2018145187A1 - Mechanical coupler for semi-trailer legs - Google Patents

Abstract

A mechanical part for transferring power from one system to another in a semi-trailer leg actuator assembly.

Description

 PATENT

 Title:

 Mechanical coupler for crutches of semi-trailer.

Description

 1: The mechanical part of this application is a coupler specially adapted to be driven by a geared motor and thus directly transfer the power over the manual drive shaft of a semicircle jack lifting system.

2: Allowing the activation of the motorized stand, with the principle easiest and effective today can be decoupled within seconds of the drive shaft of the stand, allowing the use of the axis manually.

3: The idea came to me when I watched a trucker work very hard to activate crutches and in difficult weather conditions. I then looked at the patent applications for motorized crutch, to realize that no product was really viable. So I innovate to finish with an excellent product having as particularity the coupler.

Illustrations:

 The illustration sheet is only for explanation and visual representation of the principle. It does not represent precise details or specific dimensions because the coupler may vary slightly in shape to accommodate different motor group and / or different stand group.

Drawing 1

indicative no: 1 represents an idea of the coupler (1). In this illustration can be perceived a shoulder (2), a pin (3) to transmit the power on the drive shaft, a key (6) to transfer the power of the motorized system on the coupler (1).

Code no: 7 represents a bolt (7) for retaining the coupler (1) in the power system. A restraint segment could also perform this function.

 Code no: 3 represents the release pin (3) which can take other forms but still retains the same function.

Code no: 14 represents a view from inside the coupler (1). This orifice allows the introduction of the coupler (1) on the manual drive shaft (5) which is illustrated in drawing No. 3.

Drawing 2

Figure A

This illustration shows an interior view of a gearbox (11) to which the coupler (1) has been incorporated on a gear so that it becomes an integral part of the gearbox (11). Although it is more effective to incorporate the coupler (1) to the gearbox (11) this does not change its function and claim that it be incorporated or added. Figure B

This illustration shows a motor (10) coupled to a gearbox (11) to which a coupler (1) is installed.

Drawing 3

Code No: 13 represents a semitrailer leg bracket.

Code no: 5 represents the manual training axis

Code no: 8 represents the crank used for the manual operation of the crutch system.

 Dial No: 9 represents the manual system housing.

Code no: 10 represents an example of a motor generating your power for the motorized operation.

Dial No: 11 represents a speed reduction system used to adjust the desired speed of rotation.

Code No: 12 represents the coupler (1) installed or incorporated in a gearbox

(12).

Claims

Claims:  1- Allows the power of a motorized system to be transferred over the axis and not at the end of the manual drive shaft of a semi-trailer crutch system 2- This coupler has the distinction of being disengageable from the drive shaft of the semitrailer stand system
