six.7.dos.1 With respect to the pursuing the process, determine the new threshold level of common diaphragm leakages-style of failure (otherwise comparable amount of leaks on heavens chamber that features you to diaphragm) at which the new car’s vehicle parking brakes getting unreleasable. That have an initial reservoir system and provide line pressure regarding a hundred psi, zero applying of the vehicle’s brake system, and, if for example the automobile is designed to pull a car armed with air brake system, a great 50 cubic inch attempt tank linked to the supply line coupling, expose an effective leakage-kind of inability of your prominent diaphragm (otherwise comparable leakage throughout the heavens chamber that features one diaphragm). Make a parking braking system app because of the venting leading supply line coupling into atmosphere, and relieve brand new demands in all of your car’s reservoirs so you can zero. 6.step three.2 are actuated and you may secure the vehicle parking braking system programs with sufficient parking retardation pushes to fulfill minimal overall performance given in either 6.step 1 otherwise six.dos. Do this procedure having more and more coming down or increasing profile (any enforce) regarding leakages-kind of diaphragm failures otherwise comparable leaks, to search for the minimal number of popular diaphragm leaks-kind of failure (otherwise comparable level of leaks throughout the air chamber which has one to diaphragm) at which all the technical setting labeled from inside the six.step three.dos continue to be actuated and you will hold the parking braking system software with sufficient vehicle parking retardation forces to satisfy minimal show given in either six.step 1 or six.dos.
Pressurize the production line from the hooking up the newest trailer’s side likewise have range coupling with the also have line portion of the trailer try rig (Profile 1) towards the regulator of trailer test rig lay at the one hundred psi, to discover whether all technical function labeled into the S5
188.8.131.52 Within amount of preferred diaphragm leakages-particular incapacity (otherwise equivalent quantity of leakages regarding air chamber with one diaphragm) determined inside six.7.dos.step one, and making use of next process, influence the new endurance restriction reservoir leaks speed (in the psi a minute). Which have an initial reservoir system and provide line tension away from 100 psi, no application of the vehicle’s brake system and you can, if for example the automobile was created to pull a car or truck equipped with heavens brake system, a good 50 hornet ne demek cubic inches decide to try reservoir connected to the rear supply range coupling, build a vehicle parking braking system software from the ventilation the front have line coupling toward atmosphere. Influence the most tank leakage price (during the psi a minute), the restrict speed from decrease in air pressure from any of the car’s reservoirs you to definitely abilities next vehicle parking brake app.
six.7.2.step 3 By using the following the techniques, a great leakage-variety of failure of preferred diaphragm (or similar leaks on heavens chamber which has one to diaphragm) you to results in a max tank leakages rate that is three times the fresh new threshold limitation reservoir leaks rates computed for the 184.108.40.206. With a primary tank system and supply line tension off a hundred psi, no applying of some of the automobile’s brakes and, if the car is made to tow a motor vehicle equipped with heavens brakes, a good fifty cubic inches shot tank linked to the rear likewise have range coupling, generate a parking brake software of the ventilation leading have line coupling to the environment. Determine the maximum tank leakage speed (during the psi for each minute), the maximum rates regarding reduction of sky pressure of any of the vehicle’s reservoirs that efficiency upcoming parking braking system software. The level of well-known diaphragm leakages-type of inability (otherwise similar level of leakage on sky chamber that features you to diaphragm) of that it tank leaks rate ‘s the top that is for usage underneath the alternative set forth for the 6(b).
7 Disaster brakes for automobiles and buses. 1, adapts to the requirements of eight.step one compliment of 7.step three. But not, the new truck percentage of a vehicle transporter shouldn’t have to meet with the drive conditions regarding seven.step 1 and you can 7.3.
