Abstract
The invention discloses a hydraulic chain tensioner device. The structure is as follows: a tensioner fastening seat and a sprocket chamber are fastened and connected through threads, the forefront end of the tensioner fastening seat abuts against a plunger, and the plunger is arranged in a plunger bushing; a check valve and a return spring are sequentially arranged between the plunger and the plunger bushing, and the return spring is arranged in an oil storage chamber of the plunger bushing; a tensioner fastening seat oil chamber is communicated with a plunger oil chamber, and a transverse oil duct and a longitudinal oil duct are arranged in the tensioner fastening seat oil chamber; and a guide plate contacts the outer end of the plunger bushing and is fixed with the sprocket chamber through bolts, and a chain is arranged in a guide plate positioning groove. The device adopts sprocket drive, so the engine has the advantage of simple structure and compact layout. The tensioner can ensure the smooth sprocket drive, and has proper tension for the chain. The hydraulic chain drive can obviously reduce the noise. The invention is especially suitable for overhead camshaft engines, and has high popularization value.
Description
Technical field
The invention belongs to engine component, be specifically related to a kind of device of hydraulic chain tensioner parts.
Technical background
Along with the continuous lifting of automobile industry each side technology, the power of motor also constantly increases, and the purpose of the technological improvement of doing, and is to improve car load transmission performance and simplified structure.At present, the driving structure of motor adopts belt transmission and gear transmission more, and the belt transmission noise is little, but causes belt slippage easily, and pulley speed can not be rotated by desirable velocity ratio, thereby reduces the transmission efficiency and the power of motor.Mostly the used gear of gear transmission is helical gear, and its machining accuracy is high, except that increasing cost, because gear is comparatively thick and heavy, has therefore increased the weight of motor, and meanwhile rotational noise is also bigger.In addition, a certain amount of gap to be reserved between the belt tensioner of mechanical rigid structure and the chain at present, also bigger noise will be produced during chain work.Thereby the existing technological deficiency of engine-driving structure to present sprocket wheel and chain transmission the present invention proposes the hydraulic chain belt tensioner, and when guaranteeing chain tensioner degree, the noise that the sprocket wheel running is produced obviously reduces.
Summary of the invention
The purpose of this invention is to provide a kind of hydraulic chain tension device device.
The present invention realizes through following technological scheme: hydraulic chain tension device device has: the fastening seat of tension device, sprocket wheel chamber, plunger, plunger bushing, check valve, Returnning spring, guide plate, bolt, snap ring and seal washer etc.The fastening seat of tension device is connected through screw threads for fastening with the sprocket wheel chamber, and the fastening seat of tension device is close to plunger foremost, and plunger places in the plunger bushing.Be provided with check valve and Returnning spring between plunger and the plunger bushing successively, and Returnning spring places in the reservoir compartment of plunger bushing.The fastening seat of tension device oil pocket is communicated with the plunger oil pocket, is provided with horizontal oil duct and vertical oil duct in the fastening seat of the tension device oil pocket.Guide plate contacts with the plunger bushing outer end, and guide plate is fixed through bolt and sprocket wheel chamber, and chain places in the guide plate locating slot.Its working principle is that guide plate one end is fixed, and an end movable (contact with piston) utilizes the oil pressure of lubricant oil to promote guide plate and produces displacement, the pressure of hydraulic pressure tensioner valve is acted on the chain, thereby make the chain tensioner, and the degree of its tensioner makes things convenient for adjustable.On the basis that guarantees the chain reliably working, the noise that reduces sprocket wheel and chain simultaneously and produced.
Characteristics of the present invention and beneficial effect be, adopts sprocket driving to make that engine structure is simple, compact in design.Tension device can guarantee that sprocket driving is smooth-going, has the suitable tensioner degree of chain, and the hydraulic chain transmission is reducing noise obviously, and the present invention is specially adapted to the motor of camshaft overhead, has very high promotional value.
Description of drawings
Fig. 1 is the principle of the invention and structural representation, also is that Fig. 2 AA is to sectional drawing.
Fig. 2 is a principle of the invention structure embodiment schematic representation.
Embodiment
Below in conjunction with accompanying drawing and through specific embodiment principle of the present invention and structure are described further.Hydraulic chain tension device device (like Fig. 1), its structure is: the fastening seat 1 of tension device is fastenedly connected through screw thread 3 with sprocket wheel chamber 2 (empty frame part among Fig. 1), and the fastening seat of tension device is close to plunger 4 foremost, and plunger places in the plunger bushing 5.Be provided with check valve 6 and Returnning spring 7 between plunger and the plunger bushing successively, and Returnning spring places in the reservoir compartment 8 of plunger bushing.The fastening seat of tension device oil pocket is communicated with plunger oil pocket 9, is provided with horizontal oil duct 10 and vertical oil duct 11 in the fastening seat of the tension device oil pocket.Contact with the plunger bushing outer end to plate 12, guide plate is fixed (like Fig. 2) through bolt 13 and sprocket wheel chamber, and chain 14 places in the guide plate locating slot, and this chain is used for the drive cam shaft sprocket wheel.Plunger is provided with snap ring 15, is provided with seal washer 16 between fastening seat of tension device and the sprocket wheel chamber.
During engine operation, plunger bushing forms interior slip along plunger and sprocket wheel chamber under the effect of oil pressure, and the effect of snap ring is the range that limits plunger bushing.Guide plate only right-hand member is fixed, and promptly the guide plate left end does not fixedly contact with the plunger bushing front end.Tension device chain when assembling just has certain pre-tightness, and when motor is started working, along with the increase of rotating speed and load, motor main oil gallery internal pressure raises, and main oil gallery lubricant oil is circulated.Horizontal stroke, the vertical oil duct of lubricant oil in the fastening seat of tension device oil pocket gets into the plunger oil pocket in the main oil gallery; When pressure reaches certain value; Check valve (moving to right) is opened, and lubricant oil can get into the reservoir compartment in the plunger bushing, and plunger bushing produces displacement to the right under the effect of oil pressure; Make guide plate compress chain, guarantee the transmission power of sprocket wheel thus.When the main oil gallery internal pressure descended, the check valve return that under the effect of Returnning spring, (moves to left) was closed the reservoir compartment in the plunger bushing, can make the reservoir compartment of plunger bushing keep certain internal pressure like this, guarantees the tensioner degree of chain with this.
