日产(NISSAN)载重车采用双管路气压制动系。本文介绍其组成、主要元件的结构和工作、调整方法及修理标准。一、制动系的组成和工作图1及图2分别为日产载重及牵引车的制动系组成简图。空气压缩机产生的压缩空气贮存在贮气筒中。气压调节器使贮气筒中的气压保持在5.5～7公斤/厘米~2的范围内。当踩下制动踏板时,制动控制阀中的上阀和下阀的开启程度对应于制动踏板踩下的程度。此时,压缩空气自制动控制阀进入继动阀,推动膜片而使继动阀中的进气阀开启(参看
Nissan (NISSAN) truck with double-pipe air brake system. This article describes its composition, the structure and work of the main components, methods of adjustment and repair standards. First, the composition and work of the braking system Figure 1 and Figure 2, respectively Nissan truck and the braking system components diagram. Compressed air from the air compressor is stored in the air reservoir. The pressure regulator keeps the air pressure in the cartridge within the range of 5.5 to 7 kg / cm2. When the brake pedal is depressed, the opening degree of the upper valve and the lower valve in the brake control valve corresponds to the degree of depression of the brake pedal. At this point, the compressed air from the brake control valve into the relay valve, push the diaphragm so that the relay valve in the intake valve open (see
