Kusiyana kwa Ntchito — Mbuye Amapanga Kupanikizika, Kapolo Amakutembenuza
Silinda yayikulu ya clutch ndi silinda ya kapolo ya clutch ndi zigawo ziwiri zosiyana za hydraulic zomwe zimagwira ntchito zosiyanasiyana. Silinda yayikulu imayikidwa mbali ya injini ya firewall, yolumikizidwa mwachindunji ndi chogwirira cha clutch pedal. Woyendetsa akakanikiza pedal ya clutch, chopondera chomwe chili mu silinda yayikulu chimakankhira pistoni yoyamba patsogolo, ndikukakamiza madzi a hydraulic (madzi a brake kapena mafuta amchere, kutengera zomwe wopanga galimotoyo wanena) kudzera mu chitoliro cha clutch kupita ku silinda ya kapolo. Silinda ya kapolo imayikidwa pa nyumba ya belu la gearbox, ndipo kuthamanga kwa hydraulic kukalowa mu silinda ya kapolo, kumakankhira silinda ya kapolo ya clutch pushrod motsutsana ndi foloko yotulutsa clutch, yomwe imachotsa clutch disc.
Dayamita ya bore ya master cylinder nthawi zonse imakhala yayikulu kuposa dayamita ya bore ya slave cylinder mu awiri ofanana bwino - master cylinder bore nthawi zambiri imakhala 20-26 mm, ndipo slave cylinder bore nthawi zambiri imakhala 16-22 mm. Chiŵerengero cha bore (master bore ÷ slave bore) chimatsimikizira mphamvu ya hydraulic leverage. Pa galimoto ya DAF CF kapena XF series, chiŵerengero cholondola cha bore ndi 1.25:1 mpaka 1.35:1. Pa IVECO Stralis kapena S-Way, chiŵerengero cholondola ndi 1.15:1 mpaka 1.25:1. Wogula fleet akayitanitsa master cylinder yokhala ndi bore ya 24 mm ndi slave cylinder yokhala ndi bore ya 18 mm (chiŵerengero 1.33:1) pa IVECO S-Way yomwe imafuna chiŵerengero cha 1.20:1 idzapanga pedal yomwe imamva yolemera 18% kuposa zomwe OE imanena - oyendetsa fleet adzadandaula za kutopa kwa miyendo paulendo wautali.
Kufananiza Bore-Stroke — Gawo Limodzi Lofunika Kwambiri
Kuphatikiza kwa bore-stroke kuyenera kutsimikiziridwa kwa silinda ya master ndi ya slave musanayike oda ya bulk. Master cylinder stroke ndi mtunda womwe piston imayendera mkati mwa master cylinder bore pamene clutch pedal yatsekedwa mokwanira - nthawi zambiri iyi ndi 25-42 mm pakugwiritsa ntchito magalimoto olemera. Slave cylinder stroke ndi mtunda womwe piston ya slave imayendera kuti ikankhire foloko yotulutsa clutch - nthawi zambiri ndi 12-20 mm. Kusuntha kwamadzimadzi kwa master cylinder (bore area × stroke) kuyenera kufanana kapena kupitirira pang'ono kufunikira kwamadzimadzi kwa silinda ya slave.
Ndakonza dongosolo la batch kuchokera kwa wogulitsa magalimoto aku Europe yemwe adalamula ma clutch master cylinders 200 okhala ndi stroke ya 22 mm bore × 30 mm, ophatikizidwa ndi ma slave cylinders 200 okhala ndi stroke ya 18 mm bore × 16 mm. Kusamutsa kwa master cylinder kunali π × (11 mm)² × 30 mm = 11,404 mm³. Chofunikira cha slave cylinder chinali π × (9 mm)² × 16 mm = 4,072 mm³. Kusamutsa kwa master cylinder kunali nthawi 2.8 kuposa chofunikira cha slave cylinder - chiŵerengerochi chinali mkati mwa mulingo wovomerezeka (2.5:1 mpaka 3.5:1) wa truck model, ndipo batch idavomerezedwa pambuyo pa mayeso ogwirizana pa galimoto yachitsanzo. Lamulo lomwe ndimagwiritsa ntchito: kusamutsa kwa master cylinder kuyenera kukhala nthawi 2.8–3.2 kuposa kusamutsa kwa slave cylinder ya pair yogwirizana bwino pa heavy truck clutch system yokhala ndi hydraulic release bearing, ndi nthawi 2.0–2.5 pa system yokhala ndi mechanical clutch release fork.
