Abstract
The invention relates to an integrated lower crankcase of an engine. The left side of an integrated lower crankcase (1) is provided with two lubrication pump oil pumping channels, two lubrication pump oil compressing channels, a lubrication pump oil return channel and a lubricant cavity; two lubricant collecting grooves are arranged in the middle and respectively arranged in fort of and behind the integrated lower crankcase (1); the right side of the integrated lower crankcase (1) is provided with two cooling backwater channels, two cooling water inlet channels, a lubrication oil filter connecting channel and a main lubrication oil channel connector, wherein an engine oil pump (16) is connected with the lubrication pump oil pumping channels, the lubrication pump oil compressing channels and the lubrication pump return oil channel; an engine oil filter (17) is connected with the lubrication oil filter connecting channel; a heat exchanger is connected with the cooling backwater channels and the cooling water inlet channels. According to the invention, the integrated lower crankcase has compact structure, small volume, large power density, simple pipe connection and is convenient to install and maintain.
Description
Technical field
The invention belongs to engine art, be specifically related to the integrated lower crankcase of a kind of motor.
Background technique
Development along with power technology, high power density diesel engine has become the recent tendency of power development, and high power density is high compact overall structure types to the requirement of motor general structure, this just requires motor when general arrangement, arrange compact as far as possible, the similar component of partial function adopt integrated design, reduce the existence of wasted space simultaneously, improve summation watt rating as far as possible.At present general diesel engine overall setup is loose, annex is arranged and various pipeline does not have unified design and tissue, directly cause the motor overall dimension bigger, summation watt rating is less, pipeline connects complicated, connection and sealing station are numerous, and accessibility and maintenance are relatively poor, can not satisfy the designing requirement of high power density motor Highgrade integration.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned deficiency, and a kind of compact structure is provided, and volume is little, and specific power is big, and pipeline connects simple, and installation, maintenance is the integrated lower crankcase of motor easily.
Technological scheme of the present invention: the integrated lower crankcase of a kind of motor, it comprises integrated form lower crankcase, oil pump, oil strainer, heat exchanger, the integrated form lower crankcase is an overall structure, the left side of integrated form lower crankcase is provided with two lubricating pump oil pumping passages, two lubricating pump pressure oil passages, a lubricating pump drainback passage and a lubricant reservoir, and two lubricating pump oil pumping passages and two lubricating pump pressure oil passages are symmetrical arranged; The centre is provided with two Lubricants collection grooves, lays respectively at the front and back of integrated form lower crankcase; The right side is provided with two cooling water backwater channels, two cooling water intake tunnels, a lubricating oil purifier connecting passage and a lubricant oil main oil gallery connection mouth, and two cooling water backwater channels and two cooling water intake tunnel symmetrical chiasmas are provided with; Oil pump is connected with lubricating pump oil pumping passage, lubricating pump pressure oil passage, lubricating pump drainback passage, and oil strainer is connected with the lubricating oil purifier connecting passage, and heat exchanger is connected with cooling water backwater channel, cooling water intake tunnel.
The present invention compared with prior art has following beneficial effect: 1, compact structure, volume is little, specific power is big, the oil pumping passage and the pressure oil passage of the lubricant oil of lubricating pump are set on lower crankcase, the lubricant oil collection groove, the design of integrated form, volume reduces greatly, taking out, inhaling and can make lower crankcase become dry sump by lubricant oil collection groove and lubricating pump; 2, pipeline connects simple, in lower crankcase, the Lubricants of motor and cooling liquid flow by the internal path in the lower crankcase, the quantity of crankcase seals structure is greatly reduced, prevented that effectively Lubricants is leaked to external environment condition, guaranteed the safe and reliable of engine working process thus and since lower crankcase integrated lubricating oil pipeline and cooling water pipeline, reduced the crankcase cost of production; 3, installation, maintenance is convenient, and the auxiliary system component can be pre-assembled on the lower crankcase when assembling, can be assembled on the motor with lower crankcase, have improved the assembling and the maintenance of motor complete machine.
