PTO proportional to engine speed MECHANICAL PART Description The PTO proportional to engine speed is part of the GPA 20 axle. The PTO proportional to engine speed is manufactured by Gima. The exit shaft of the PTO proportional to engine speed receives the movement from

the primary drive shaft , which then transmits it to the clutch and gears . Speed selection of the PTO proportional with engine speed is performed by yoke and cluster.

Operating laws When activating the PTO proportional to engine speed, the low pressure driving circuit sends oil into the clutch housing. The clutch spring, then the spring washer, are compressed by the piston and the friction disc are pushed

closer gradually to transmit torque. When the command is cancelled, pressure drops at 0 bar. Torque is no longer transmitted.

Description A Clutch housing.

D Gradual lockwasher.

B Movement out hubs.

E Piston.

C Neutral return spring.

F Disc and backplate stack.

The movement enters by the (A) assembly and is transmitted to the (B) hubs via the discs and backplates.

When idle (upper part of the illustration), the spring (C) pushes the piston (E) to the left, hence releasing the clutch discs.

C2.10

During the clutching phase, the piston moves to the right while compressing only the spring (C) until eliminating any play in the disc and backplate stack (scrub point).

The piston continues moving to the right while compressing the (D) washer : this results in a gradual elevation of the presser effort on the clutch discs, softening power take-off movement.

Hydraulic piloting part Description The rear PTO brake (in mode PTO proportional to engine speed or proportional to forward drive) is controlled by the solenoid valve "Y338" , which is of the On/Off type.

The supply hydraulic pressure is sourced from the tractor's hydraulic circuit

Operating laws When commanding the rear PTO brake , for example with the "S114" contact, the driving circuit sends low pressure oil into the brake's piston .

When the command is cancelled, pressure drops at 0 bar.

In this case, the effort on the bearing is zero, and the primary line is no longer slown.

The piston pushes the bearing, which increases its preload, and hence slows the primary line.

Use the kit n°00 0178 310 0 to perform measurements and read then on a computer.

– Actuate the brakes over the entire stroke of the pedals.

The point is to display the curves of the different types of braking (service, brake, trailer hydraulic brake, air brake) to see if the tractor brakes the trailer properly.

– Record pressure, which must be 70 bars for service brakes fitted with "boosters". The trailer hydraulic braking pressure is 140 +/- 5 bars. The trainler air braking pressure is 8 bars.

Note: Following this check, the braking system must be drained (see chapter "C" in the repair folder).

This equipment is optional. Pneumatic braking on the trailer offers several benefits: – High braking capacity.

– Highly responsive braking.

– Use of clean fluid.

– Trailer immobilized in case of breakage of hoses.

The pneumatic elements used in the trailor's braking system are made by Wabco. The tractor's pneumatic braking system adapts to both types of braking systems which can be foundon a trailor.

• A single coupling sleeve = black coupling head.

This is therefore a negative braking system.

C6.4

Arion 630-610 C – 1.2009 – GB

General description This is thus a positive braking system: • Pressure from the yellow coupling head pilots the displacement of the spool in the emergency relay valve.

• A rupture to the hose at the coupling (for example during mechanicla rupture of the coupling between the tractor and the trailor) causes the trailer to stop. The release valve, however, allows the trailer to move in this case by using the compressed air in the reservoir.

Characteristics The pneumatic braking circuit is supplied with compressed air at 8 bar. Trailer braking is proportional to the force on the brake pedals (pedals coupled together).

Pneumatic brake MECHANICAL PART Description 7002p

When the handbrake lever is pulled, the handbrake lever control cable drives the control lever (C) in rotation around its axis . The rod (B) then actuates the pneumatic valve control lever (A). The valve sends into the rest of the circuit the pneumatic signal required for pneumatic trailor braking.

Pneumatic brake

– Check the tank is pressurized.

– If pressure measured on the black coupling head "5003p" is not correct, adjust the control rod by screwing or unscrewing it.

– Look at the pressure gauge "6001p" in the cab.

– Lock the 2 locknuts once the setting is compliant.

The pressure should be 8 bar. If required, start the tractor to inflate the tank.

The pneumatic braking actuation rod (B) is fastened to the handbrake actuation lever (C)(in the first index) and on the control lever of the pneumatic valve (A).

– Connect the pressure gauge "6001p" onto the black coupling head.

Hand brake release: The pressure should be 5 bar.

When the handbrake is set at 2 to 4 notches, pressure must be 0 bars.

The pressure gauge allows monitoring the status of the pneumatic circuit while indicating continuously the value of pressure inside the circuit. The main control valve is controlled mechanically by the handbrake (B) and hydraulically by the brake valve (E) of the tractor. The main control valve informs the rest of the circuit on the status in which the tractor is (braking phase or drive valve).
