Description
Frein pour trains routiers, notamment pour trains routiers
automobiles.
Le présent perfectionnement est relatif à un frein pour
trains routiers, notamment pour trains routiers automobiles, décrit
dans le brevet principal N[deg.] 444. 447, qui comporte une soupape commandée par l'effort au timon, montée sur la remorque, et un organe
de commande qui,lors d'une variation de pression provoquée depuis
le tracteur, en vue de freiner la remorque, dans la conduite raccordée entre le tracteur et la remorque, ouvre une d rivation contournant la soupape commandée par l'effort au timon et relie dans ce
cas le cylindre de frein de la remorque, par la d rivation, au réservoir de fluide sous pression monté sur la remorque. Quand dans ce
frein la soupape commandée par l'effort au timon est conformée <EMI ID=1.1>
avec l'atmosphère déjà pour des efforts rolativanent faibles exercés sur le timon, il peut advenir - par exemple quand le train routier descend une côte avec le frein du tracteur desserra - que

Brake for road trains, in particular for road trains
automobiles.
This improvement relates to a brake for
road trains, in particular for automobile road trains, described
in main patent N [deg.] 444. 447, which comprises a valve controlled by the drawbar force, mounted on the trailer, and a member
control which, during a pressure variation caused from
the tractor, in order to brake the trailer, in the pipe connected between the tractor and the trailer, opens a bypass bypassing the valve controlled by the drawbar effort and connects in this
in the case of the trailer brake cylinder, through the bypass, to the pressurized fluid reservoir mounted on the trailer. When in this
brake the valve controlled by the drawbar force is conformed <EMI ID = 1.1>
with the atmosphere already for low rolativanent forces exerted on the drawbar, it can happen - for example when the road train goes down a hill with the brake of the tractor released - that
<EMI ID = 2.1>
the brake cylinder of the trailer would be in communication with the atmosphere, so that "we could not brake the ronoroue or at least operate only insufficient braking despite the available
<EMI ID = 3.1>
pressurized fluid from the tank of the ranorque without any use.
To overcome this drawback, the member transmitting the movements of the control member, provided to control the bypass, is given to the valve shutter of this bypass, a shape such that the direct communication between the cycle.
<EMI ID = 4.1>
aroitc of the rod 45 passes through a seal 46 and a chamber 47. L :: rod is drilled axially to a certain depth on the side of its right end and communicates with it by <EMI ID = 5.1>
with the atmosphere. The chamber 47 is connected by a wire orifice and an adjacent conaui 52, to the compressed air tank of the trailer.
<EMI ID = 6.1>
the hole 51 as the bore of the rod 45.
In the housing 40 is further provided a chamber 55 or!
<EMI ID = 7.1>
flexible F6. To the right side of the flexible diaphragm 56 is fixed
<EMI ID = 8.1>
the right end is upstream of a supper disc 61.
<EMI ID = 9.1>
<EMI ID = 10.1>
connected the brake cylinder of the r-morque, not shown.
The hollow spindle 60 has a longitudinal bore 65
