简体中文six.7.2.step 1 With regards to the following the techniques, determine new tolerance level of well-known diaphragm leakage-method of failure (otherwise similar amount of leakages in the sky chamber which has that diaphragm) at which the new vehicle’s vehicle parking brakes become unreleasable. That have a first reservoir program and gives range stress off one hundred psi, no applying of the car’s brake system, and you will, in case your auto is designed to tow a vehicle armed with air brakes, a fifty cubic inches decide to try tank attached to the also have line coupling, present an excellent leakages-types of incapacity of your own preferred diaphragm (or comparable leaks from the sky chamber that has you to diaphragm). Build a vehicle parking braking system app of the ventilation the front likewise have range coupling for the ambiance, and reduce the new demands in all of automobile’s reservoirs so you can no. 6.step 3.2 continue to be actuated and secure the vehicle parking braking system apps with plenty of parking retardation forces meet up with the minimum efficiency given in a choice of 6.step 1 otherwise 6.2. Repeat this procedure having progressively decreasing otherwise expanding account (any enforce) from leakages-particular diaphragm failures otherwise equivalent leakage, to determine the minimal quantity of popular diaphragm leakages-particular inability (otherwise similar number of leaks regarding the air chamber that features one to diaphragm) from which all of the mechanical setting described for the six.3.2 are still actuated and you may secure the vehicle parking braking system applications with enough vehicle parking retardation forces to get to know minimal efficiency specified in a choice of 6.step one otherwise six.dos.
Pressurize the production line by hooking up new trailer’s front side supply range coupling toward also provide line part of the truck shot rig (Shape step 1) for the regulator of your trailer shot rig lay during the one hundred psi, and determine whether or not every mechanical setting regarded in the S5
six.eight.2.2 Within number of common diaphragm leaks-method of inability (otherwise equivalent level of leakage regarding air chamber that has had one diaphragm) calculated for the 6.7.dos.step 1, and using another processes, dictate the latest threshold restriction reservoir leakages price (during the psi for each minute). Which have a first tank program and supply line tension away from a hundred psi, no application of all car’s brakes and, when your auto is designed to tow a vehicle armed with heavens brake system, a great 50 cubic inch sample reservoir attached to the bottom supply range coupling, build a vehicle parking brake software of the ventilation leading supply line coupling towards the environment. Influence the utmost tank leaks rate (from inside the psi per minute), which is the maximum price out of reduction of Hindu dating review air stress of all vehicle’s reservoirs one show after that parking brake app.
S5
6.seven.dos.3 Utilizing the pursuing the procedure, a great leakages-sort of incapacity of your own preferred diaphragm (otherwise comparable leaks from the sky chamber which includes that diaphragm) you to contributes to an optimum reservoir leakage rates that is about three moments the fresh new tolerance limit tank leaks speed computed within the six.7.2.2. Which have a first tank program and supply range pressure away from one hundred psi, zero applying of any of the vehicle’s brakes and you can, when your vehicle was created to tow a car armed with air brakes, an excellent 50 cubic inch sample reservoir connected to the buttocks also provide range coupling, generate a parking braking system application of the ventilation the leading likewise have range coupling towards the conditions. Influence the most reservoir leaks rate (for the psi each and every minute), the restrict rate of reduced amount of heavens pressure of any of the automobile’s reservoirs one to abilities next parking brake app. The amount of popular diaphragm leaks-sorts of failure (otherwise equivalent quantity of leaks on the sky chamber which has had that diaphragm) on the this reservoir leakages speed ‘s the level that is for use in alternative established inside six(b).
eight Emergency brakes getting autos and you will busses. step one, adapts towards the conditions out-of eight.step one as a consequence of seven.step three. Yet not, the new vehicle portion of an automible transporter does not have to meet up with the road test conditions of 7.step 1 and you will eight.3.
