Determine the maximum tank leakage speed (within the psi a minute), which is the limitation speed away from reduced total of air stress of any of the vehicle’s reservoirs that performance following vehicle parking brake software
S5.six.six.5 The original requirements to have S5.six.6.cuatro are as follows: The new tank program and provide range is actually pressurized to help you 100 psi, utilizing the have range portion of the trailer take to rig (Profile step one).
S22.214.171.124 The exam sequence to possess S5.6.6.cuatro is just as pursue. People solitary leakages sort of inability, in virtually any most other brake system, from an associate designed to have compressed-air otherwise brake water (consistent with the parenthetical words specified in S5.6.step three.1), was brought regarding the brake system. 30 moments pursuing the initiation of such ventilation, the supply range was repressurized toward truck decide to try rig (Shape step one). 30 mere seconds following the initiation of such repressurizing of supply range, the front likewise have range are vented for the conditions. This process is conducted either by the union and you can disconnection of the supply range coupling or by the accessibility a valve strung when you look at the the production range part of the trailer sample rig near the have range coupling.
When your vehicles is designed to pull a motor vehicle equipped with air brake system, a great fifty cubic inch decide to try tank are attached to the buttocks also provide line coupling
S5.6.seven Maximum amount of prominent diaphragm leakages-form of inability/ Similar level of leakages about heavens chamber with which has you to definitely diaphragm. Regarding automobile in which the possibility inside S5.6(b) has been selected, influence the most quantity of well-known diaphragm leakages-variety of inability (or comparable number of leakages from the air chamber that features you to diaphragm) with respect to the steps established during the S5.6.seven.step one due to S5.6.eight.2.step three.
S5.6.seven.step one.step one According to following process, dictate the latest tolerance level of preferred diaphragm leakage-kind of failure (or comparable amount of leakage about air chamber which includes you to definitely diaphragm) at which the new automobile’s vehicle parking brakes getting unreleasable. That have a primary tank system stress out-of one hundred psi, the fresh new engine turned out-of, zero applying of the vehicle’s brakes, and you may, if for example the car is made to pull a car armed with sky brakes, a 50 cubic inch decide to try tank attached to the also have range coupling, expose good leakage-style of failure of one’s popular diaphragm (or similar leakages about sky chamber who has one to diaphragm). Pertain this new parking brakes by making a loan application actuation of your vehicle parking braking system manage. Reduce the demands throughout of your own automobile’s reservoirs to zero, trigger brand new system and enable they so you can sluggish, and allow the latest challenges in the car’s reservoirs to rise up until they stabilize or through to the compressor close-of section try achieved. During the time, make a release actuation of your vehicle parking brake manage, and discover whether all the mechanized setting known in S5.six.step three.dos are actuated and you will secure the vehicle parking braking system programs with enough parking retardation push in order to satisfy minimal results specified either in S5.six.step 1 otherwise S5.6.dos. Repeat this process with more and more coming down otherwise broadening levels (any type of enforce) regarding leaks-type diaphragm disappointments or equivalent leakages, to search for the minimal quantity of prominent diaphragm leakages-method of inability (otherwise similar quantity of leaks from the sky chamber with one to diaphragm) where all mechanized setting referred to during the S5.6.step 3.dos will still be actuated and secure the vehicle parking brake programs with plenty of parking retardation pushes to generally meet the minimum efficiency specified in both S5.six.step najlepsze serwisy randkowe dla geekГіw 1 or S5.6.2.
S5.six.eight.1.dos At the amount of prominent diaphragm leakage-sorts of failure (otherwise similar level of leaks on sky chamber that has had you to definitely diaphragm) calculated inside S5.six.eight.1.step 1, and using the next procedure, influence the newest threshold restrict tank rates (for the psi each minute). That have a primary reservoir program pressure of a hundred psi, the newest engine-turned of, zero applying of all automobile’s brakes and you can, in case the auto was designed to pull an automible equipped with heavens brakes, a beneficial 50 cubic inches test tank connected to the also have line coupling, apply actuation of parking brake control.
