Abstract

A mechanical work sampling system (10) is for the operation of extensions articulated in vehicular applications. The system is susceptible of being applied on a tracked vehicle (30) and includes at least a supporting arm (40) and a secondary track (22; 23) associated to the supporting arm. The supporting arm (40) is configurable in rotation configuration within which it rotates with respect to a first end (41) through a sampling of work from the main propulsor of the tracked vehicle (30).

Claims

1. A mechanical work sampling system for the operation of extensions articulated in vehicular applications;

the system being configured for use with a tracked vehicle;

said system comprising;

at least a supporting arm and a secondary track associated to said supporting arm;

said supporting arm being configurable in a rotation configuration within which said supporting arm rotates with respect to a first end through a sampling of work from a propulsor of said tracked vehicle;

a pulley adapted for being coupled to an end of said supporting arm;

wherein said pulley comprises a truncated conical section and wherein said supporting arm has on an end a body ending with a truncated conical section;

said truncated conical section of said pulley and said truncated conical section of said body being adapted for mutually coupling in use.

2. The system according to claim 1, wherein said supporting arm comprises another configuration within which said supporting arm is fixed with respect to said tracked vehicle.

3. The system according to claim 1, wherein said supporting arm comprises a second end opposed with respect to said first end;

said system further comprising a first and second wheel, positioned respectively upon said first and second end and upon which is installed said secondary track.

4. The system according to claim 1, wherein said truncated conical section of said pulley and said truncated conical section of said body are respectively of male and female type or of female and male type.

5. Tracked vehicle, comprising a mechanical work sampling system for the operation of extensions articulated in vehicular applications according to claim 1.

6. The tracked vehicle according to claim 5, configured for the overcoming steps and ramps, comprising a pair of main tracks each one installed on at least a pair of wheels, and wherein for each wheel of said pair of wheels of each of said main tracks is installed said work sampling system.

7. The tracked vehicle according to claim 5, configured for moving on ground, and wherein said supporting arm of said system, in said rotation configuration, varies an angle between said supporting arm and said ground.
