Caterpillar 140K mota grader chigadzirwa cheCaterpillar Co., Ltd. Yakasanganiswa neCaterpillar C7 injini, simba rekuchinja kufambisa uye mutoro unonzwa hydraulic mudziyo, unogona kupedzisa basa rekuyera zvakanaka uye nekukurumidza.Iyo Katsi 140K Mota Grader inokwidziridza kudzoka kwako pakudyara nekuunza kugadzirwa kwakanyanya uye kusimba.Iyo Katsi C7 injini, yakananga-drive powershift transmission uye mutoro-inonzwa hydraulics inoshanda pamwe chete kuti ive nechokwadi chesimba uye nemazvo anodiwa kuti basa riitwe.
1. Injini dzeKatsi C7 ACERT dzinosangana neUS EPA Tier 3/EU Danho IIIA yakaenzana emission standards kana Tier 2/Stage II yakaenzana emission standards zvichienderana neakananga nyika miyero.Injini inobatanidzwa ne powershift countershaft transmission nokuda kwepamusoro kuendesa simba pasi.
2. Electronic throttle control inobatsira kuwedzera kubereka kuburikidza nekugadzirisa simba uye torque kuti isangane nezvinodiwa zvesimba zvekushandisa.High blade angles, yakagadziridzwa moldboard curvature uye yakafara huro clearance inobvumira zvinhu kuti zvitenderere zvakasununguka padivi peblade kuti iwedzere kushanda zvakanaka.Pa-inoda hydraulic mafeni anogadzirisa otomatiki kumhanya kuti aenderane nezvinodiwa zvekutonhodza, kuwedzera simba rekufambisa pasi nekuvandudza kushanda kwemafuta.Injini isina basa yekuvhara chimiro inowanikwa inodzima injini mushure menguva yakatarwa, kuchengetedza mafuta uye kubatsira kuderedza kuburitswa.
3. Proportional Priority Pressure-Compensating (PPPC, Proportional Priority Pressure-Compensating) inopa kutonga kwakanakisisa, kusimbiswa kwekushanda uye kushanda kwepamusoro kwekutakura mitoro ye hydraulic systems.Iyo inosarudzika otomatiki shanduko yekufambisa inovandudza kusununguka kwekushanda uye inowedzera kugadzirwa nekubvumira kutapurirana kuchinjika otomatiki mugiya rakakwana.Rocker maoko uye control switch zviri mukati mekusvika nyore.Yakapupurirwa yakajairwa kudzora inopa indasitiri-yakajairwa kudzora mapatani uye kunzwa kune chaiyo yekucheka kumucheto kufamba.
4. Mapfekero anoiswa naironi ane tsinga anowedzera torque inotenderera uye anowedzera hupenyu hwechikamu.Brass moldboard slide kupfeka mitsetse iri pakati peiyo blade inomisikidza gungano uye moldboard uye inochinjika nyore uye inotsiviwa.Nzvimbo yeruboshwe yebasa iri padyo nepasi kuti ikurumidze kugadzirisa uye kuve nechokwadi chekugadzirisa nguva yenguva.
5. Mushandi anogona kunyatsoona moldboard mudzi uye tandem matai, kuvandudza zvibereko uye kushanda kuchengeteka.Iyo blade lift accumulator inobata mitoro inobatwa ne moldboard nekubvumira blade kuti ifambe yakatwasuka.
6. Mabhureki akaiswa pagumbo rimwe nerimwe re-double-gumbo set, uye nzvimbo yose yebhureki ndiyo yakakura mumhizha, saka simba rekugadzirisa rinovimbika zvikuru.Yakajairwa denderedzwa dhiraivha inotsvedza clutch inodzivirira iyo yekudhirowa, denderedzwa uye moldboard kubva kune inovhundutsa mitoro kana blade ikasangana nezvinhu zvakaoma-kufamba.Iyo yepasi-level injini yekudzima switch inobvumira chero munhu ari pedyo kuti avhare injini munjodzi.
