Abstract
The invention discloses a drive connecting member of a vacuum pump by pressing a camshaft sprocket structure. The drive connecting member is structurally characterized in that a drive joint main body consists of a hexagonal fastening end and a bolt section. The lower end face of the hexagonal fastening end is a vacuum pump shaft locating surface and also provided with a vacuum pump drive keyseat, and a vacuum pump shaft locating hole is arranged at the center of the bottom of the drive keyseat. The vacuum pump shaft locating hole is arranged at the center of the bottom of the drive keyseat, and the center of the bolt section is provided with a lubricant channel and a lubricant micropore. The drive connecting member is taken as a fastening member of a sprocket and a camshaft and also as the connecting member of the drive between the vacuum pump and the camshaft. The drive connecting member of the vacuum pump changes the traditional arrangement of the vacuum pump, namely the camshaft directly drives the vacuum pump. The invention provides a novel way for the drive connection structure of the vacuum pump, makes the space peripheral member arrangement of an engine be optimized, in particular improves the engine with too many belt pulleys and a rather narrow generator rear side, and also provides a novel structure design.
Description
Technical field
The invention belongs to engine part, be specifically related to a kind of link that utilizes the work of camshaft actuated vacuum pump.
Background technique
Along with the increase of automobile function, motor also must develop to compact structure, power direction powerful, that save fuel oil.Especially compact structure, annex occupy all kinds of motors in little space, become one of main target of design.Make the engine structure compactness that two kinds of methods generally be arranged: at first under the situation that satisfies the engine performance requirement, to reduce peripheral element as far as possible; Secondly, the motor outward appearance is set rationally, comprises the design of cylinder body, cylinder cap and the rational deployment of peripheral components.Its intermediate pump is as one of indispensable parts of motor, occupy certain volume in the external engine space, at present it is provided with dual mode: (1) passes through belt drives, be that vacuum pump and generator, air compressor, the moving main shafts such as pump that change are set to a rotational plane and drive with belt pulley is unified, this has strengthened the girth of belt train undoubtedly; (2) vacuum pump is installed in the rear side of generator, directly drives vacuum pump by generator shaft.Owing to reduced by a train, so belt train girth also can shorten relatively.But generator and the coaxial setting of vacuum pump must make entire length increase, because the generator ear end face need be reserved the vacuum pump space.The present invention proposes to adopt camshaft to drive vacuum pump, and this problem is resolved.
Summary of the invention
The objective of the invention is, provide a kind of and drive the link device by the vacuum pump that compresses the camshaft sprocket structure.
Below in conjunction with accompanying drawing structural principle of the present invention is described.The structure composition that vacuum pump drives link comprises: six side fastening ends, vacuum pump axially locating surface of contact, vacuum pump drive pin slot, lubricant oil micropore, bolt section and vacuum pump shaft positioning hole.For vacuum pump provides the principle of power source be: camshaft sprocket is connected by chain with crankshaft sprocket, and engine crankshaft is passed to camshaft with power by two sprocket wheels, and the effect that drives link is with camshaft and ingenious connection of vacuum pump (axle).Therefore make the technological scheme of engine structure compact design be: vacuum pump drives link and is made of six side fastening ends and bolt section two-part, and the lower end surface of six side fastening ends is as the locating face that is connected with the vacuum pump shaft; Bolt section and sprocket wheel and camshaft are fastening.The concrete connection of vacuum pump is (vacuum pump) drive pin slot that relies on lower end surface, six side fastening ends to be provided with, and drive pin slot bottom center is provided with vacuum pump shaft installing and locating hole, for the lubricated link center that drives is provided with grease channel.The front end that drives link bolt section is provided with the lubricant oil micropore, and the lubricant oil micropore is positioned at vacuum pump shaft hole centre line.The present invention has changed the original layout general layout of aforementioned vacuum pump, promptly directly drives vacuum pump by camshaft.
Description of drawings
Fig. 1 is a stereochemical structure schematic diagram of the present invention.
Fig. 2 is the invention process illustration.
Embodiment
Below in conjunction with accompanying drawing and by embodiment structure of the present invention is further described.The structure that vacuum pump drives link is: constitute driving link body by six side fastening ends 1 and bolt section 5, the lower end surface of six side fastening ends 1 is a vacuum pump shaft locating face 2.Be provided with vacuum pump drive pin slot 3 in 1 lower end surface, six side fastening ends, drive pin slot bottom center is provided with vacuum pump shaft positioning hole 6, and the bolt center is provided with grease channel.The front end of bolt section 5 is provided with lubricant oil micropore 4, and lubricant oil micropore 4 is positioned at vacuum pump shaft positioning hole 6 center lines.Driving link body total length is 50mm; Wherein bolt section 5 external thread lengths and external diameter are M14 * 18.5; Lubricant oil micropore 4 apertures and the degree of depth are Φ 1 * 5mm; Vacuum pump shaft positioning hole 6 apertures and the degree of depth are Φ p8 * 10mm.
The bolt section 5 that drives the link body is passed sprocket wheel 8 and is connected with camshaft 9 and tightens; The axle of vacuum pump 7 is inserted in the vacuum pump shaft positioning hole 6, and the driving pin embedding of vacuum pump is crouched in the drive pin slot 3 of going into the drive sub body.Drive link and have two effects: one is the fastening piece as sprocket wheel and camshaft, and another is the link as transmission between vacuum pump and the camshaft.The engine crankshaft sprocket wheel is connected by chain with sprocket wheel on the camshaft, and to the sprocket wheel on the camshaft, so the rotation of camshaft drives vacuum pump run-in synchronism by driving link (driving pin) to crankshaft sprocket, drives vacuum pump work with power transmission.The effect of vacuum pump shaft positioning hole is to prevent that the vacuum pump diameter of axle to play, can guarantee the vacuum pump shaft balancing; The seat surface of vacuum pump shaft locating face and vacuum pump driving pin is fitted, and prevents vacuum pump shaft axial float.Lubricating oil in the cylinder cap enters in the vacuum pump drive pin slot by the vacuum pump axially locating hole and the oilhole of drive sub body, plays the effect of lubricated cooling vacuum pump shaft and vacuum pump driving pin and drive pin seat and vacuum pump axial locating surface surface of contact.
Characteristics of the present invention are that simple in structure, the effect of stationary cam axle sprocket wheel had both been played in the little easy installation of volume, can drive vavuum pump work by drive pin slot again. This device has been for the design of the drives structure of vavuum pump has supplied new on-link mode (OLM), makes that the peripheral element layout is optimized between engine air. Even adopt the present invention by belt drives, can reduce by a belt pulley, the belt entire length is shortened; If driven by generator shaft, this device also can shorten the length that generator shaft and vavuum pump axially are connected. Particularly for the more and generator rear side of belt pulley quantity very narrow and small engine improve, new structural design is provided.
