Abstract
The utility model discloses a bottom-mounted automobile engine balancer. The engine-driven wheel hub assembly comprises a shell (1), wherein a positioning pin (2) connected with an engine is arranged at the top of the shell (1), a mounting hole (3) is formed in the shell (1), a wheel hub (4) is arranged at one end of the shell (1), and the wheel hub (4) is rotatably connected with an idler wheel (5); the other end of the shell (1) is provided with a cavity (6), a balance block (7) is arranged in the cavity (6), and a balance shaft (8) is arranged on the balance block (7). Because the bottom-mounted automobile engine balancer of the utility model is arranged at the bottom of the automobile engine, the mutual position between the balance block and the crankshaft in the engine can be conveniently adjusted, and the best effect of offsetting the vibration generated when the crankshaft of the engine works is achieved; in addition because the utility model discloses be located the engine below, can improve the lubricated effect between balanced axle and the shaft hole, reduce the wearing and tearing between balanced axle and the shaft hole, prolong the life of balancer.
Description
Technical field
The utility model relates to a kind of engine balance apparatus, particularly a kind of bottom type motor car engine balace weight.
Background technique
Along with improving constantly of human scientific and technological level, people also propose high requirement to the power performance and the travelling comfort of automobile thereupon.But along with the increase of automobile power, the vibration of motor car engine is aggravation thereupon also, for the vibration that reduces to produce when motor car engine is worked, balace weight need be installed on motor.The working principle of balace weight is to produce the vibration of rightabout vibration when offsetting engine operation when relying on balace weight work.Traditional balace weight is assemblied in the side of motor car engine, because the trunnion shaft rotating speed height of balace weight (be at least engine crankshaft rotating speed 2 times), and eccentric equilibrium block is housed on the trunnion shaft, and there is bigger vibration in self when the trunnion shaft high speed rotating.Owing to influenced by the wobbler action power of equilibrium block, influence the relative positional accuracy requirement of equilibrium block and engine crankshaft; Need the lubricating requirement that Injection Pump guarantees motor and balace weight be installed separately on motor, will increase the input power chain of Injection Pump simultaneously, the structure relative complex.If lubrication system can not satisfy the above requirement, can make the balace weight premature failure because of lubricated insufficient serious wear that causes between trunnion shaft and the axis hole, influence the working life of balace weight.
The model utility content
The purpose of this utility model is, provides a kind of simple in structure, is installed in the bottom type motor car engine balace weight of car engine motor spindle.It can better offset the vibration that produces when engine crankshaft is worked, and improves the lubrication effect of balace weight, prolongs the working life of balace weight.
The technical solution of the utility model.A kind of bottom type motor car engine balace weight.Comprise housing, case top is provided with the locating stud that is connected with motor, and housing is provided with mounting hole, and housing one end is provided with wheel hub, and wheel hub and idle pulley are rotationally connected; The housing the other end is provided with cavity, is provided with equilibrium block in the cavity, and equilibrium block is connected with trunnion shaft, and cavity is provided with end cap.
In the above-mentioned bottom type motor car engine balace weight, described wheel hub is rotationally connected through needle bearing and idle pulley.
In the aforesaid bottom type motor car engine balace weight, described housing is provided with two mounting holes, and two mounting holes are connected with engine oil pump assembly on the automobile.
In the aforesaid bottom type motor car engine balace weight, described two mounting holes are rotationally connected through the transmission shaft at needle bearing and engine oil pump assembly two ends respectively.
In the aforesaid bottom type motor car engine balace weight, described idle pulley respectively with crankshaft gear and engine oil pump assembly one end transmission shaft on driving gear engagement.
In the aforesaid bottom type motor car engine balace weight, the trunnion shaft on the described equilibrium block is connected with driven gear on the engine oil pump assembly the other end transmission shaft.
Compared with prior art, because bottom type motor car engine balace weight of the present utility model is installed in the bottom of motor car engine, can adjust the mutual alignment between the bent axle in equilibrium block and the motor easily, vibrative effect when reaching best counteracting engine crankshaft work; Because the utility model is positioned at the motor below, the mounting point with oil pump merges on the balace weight simultaneously, and uses available dynamic source on the balace weight, makes mechanism simple in addition; Because balace weight places the bottom of motor, be in the engine sump tank, therefore the major part of balace weight is immersed in the lubricant oil of motor, and the oil return of other lubricating oil path of motor is the bottom of flow direction engine all, so the lubrication system of the balace weight of bottom type is relatively fully with reliable, can improve the lubrication effect between trunnion shaft and the axis hole, reduce the wearing and tearing between trunnion shaft and the axis hole, prolong the working life of balace weight.
