ABSTRACT:
A clutch pedal operated rod to the brake lever in a transmission brake system for tractors and the like is formed of two spaced longitudinally aligned rod lengths connected by a coupling for transmitting force therebetween through a fluid medium. The coupling is secured to the end of one length and slidable receives a spring loaded piston head on the aligned end of the other length. The piston head is in fluid seal engagement with the coupling and separates such coupling into an upper and lower chamber with a fluid supply disposed in the upper chamber in non-operating position. A fluid conduit exteriorly of the coupling communicates with both chambers. Depression of the clutch pedal effects relative movement of the piston head against the fluid supply in the upper chamber where the fluid acts as a solid member under pressure to transmit force to the brake operating rod for stopping the transmission. The entrapped fluid under pressure from the piston head flows through the conduit at a rate controllable by an adjustable needle valve from the upper chamber to the lower chamber as the force exerted on the brake rod effects stoppage of the transmission and at the completion of such flow, the force transmitting connection between the aligned brake lever operating rod lengths is terminated by the exhaustion of the fluid supply in the upper chamber so that with the clutch pedal depressed and the transmission stopped, there is no pressure on the transmission or the gears and the gears can be easily and smoothly shifted. Release of the clutch pedal effects relative movement of the piston head away from the upper chamber towards and into the lower chamber to a predetermined degree sufficient to effect the flow of the fluid supply through the conduit back to the upper chamber for the next actuation of the brake.
