Abstract
A tow stabilizer device intended to distribute part of the load at the end of a tow frame on a level with the swivel joint of the coupling to the front and rear wheels of the towing vehicle and to the wheels of the tow frame while eliminating the swaying and rolling effects. The stabilizer includes a leaf spring or spring leaf at one end thereof articulated on a jaw and kept articulated in a vertical line with the support axis of the coupling's swivel joint. The jaw is braked in its lateral displacements by means of friction disks. The other end of the spring is connected by a screw jack to a crosspiece which is attached to the arms of the tow frame by flexible connections. Each of the flexible connections rest on a hinged bracket which is positioned on arms permitting the swerving of the assembly of the crosspiece and the spring leaf.
Claims11
A tow stabilizer for a tow frame for coupling to a towing vehicle, said vehicle having a coupling attached thereto for connection with said tow frame, comprising:
- spring means including first and second ends, said spring means extending along a substantially horizontal axis of the tow frame relative to the vehicle roadway;
- clamping means including means for connection to said towing vehicle, said clamping means including an axle having an axis which is substantially parallel to the roadway, and extending in a direction transversely to the horizontal axis of said tow frame, said clamping means including locking pins and apertures for receiving said locking pins;
- said first end including means pivotally connecting said spring means with said axle for movement in a vertical plane relative to said clamping means, said spring means being positioned between said locking pins, and said locking pins controlling the amount of movement of said spring means in the vertical plane;
- said clamping means being pivotally mounted about a vertical axis and including friction means, said friction means braking the pivotal displacements of said clamping means;
- a pair of arms connected together at one end thereof and with said coupling, the other end of said arms extending in a plane substantially parallel to the roadway and diverging from said coupling;
- a crosspiece, flexible connections connecting said crosspiece with the other end of said arms;
- and
- a rigid tension member connected with the center of said crosspiece and second end of said spring means and connecting said spring means with said arms by means of said flexible connections with said arms forming said tow frame to distribute the tensile stress produced over each of said shaft arms.
A tow stabilizer for a tow frame for coupling to a towing vehicle, said vehicle having a coupling attached thereto for connection with said tow frame, comprising:
- spring means including first and second ends, said spring means extending along a substantially horizontal axis of the tow frame relative to the vehicle roadway, said spring means including a spring element oriented to a defined vertical position
- clamping means for connection of said spring means to said towing vehicle, said clamping means including engageable means operatively associated with said coupling;
- said first end including means pivotally connecting said spring means with said clamping means in a vertical plane relative to said defined vertical position;
- said clamping means including wedges which immobilize said spring element in said defined vertical position;
- a pair of arms connected together at one end thereof and with said coupling, the other end of said arms extending in a plane substantially parallel to the roadway and diverging from said coupling;
- a crosspiece, flexible connections connecting said crosspiece with the other end of said arms;
- and,
- a rigid tension member connected with the center of said crosspiece and said second end of said spring means and connecting said spring means with said arms by means of said flexible connections with said arms forming said tow frame to distribute the tensile stress produced over each of said shaft arms.
