Description
Technical field
The utility model belongs to automobile technical field, relates to a kind of timing chain tension device of motor.
Background technique
In recent years, along with the development of high-speed chain drive technology, timing chain transmission becomes one of main kind of drive of timing system.Along with improving constantly of engine performance, chain wear becomes one of principal mode of chain inefficacy, especially under high rotating speed high load, the chain beat causes its serious wear, thereby make the engine noise aggravation, this has not only reduced motor NVH performance and service life of chain, and mechanical loss is increased, when serious even the phenomenon such as chain eccentric wear fracture occurs, this will cause motor normally to move.And in the design of present most of motor, chain and motor are with the life-span, and this just need to consider the replacing of engine maintenance and chain.
The disclosed patent of Chinese patent literature for example, a kind of correct time chain driving system of motor [notice of authorization number: CN201496113U], the described chain tension rail of this patent is poor to the guidance capability of chain, timing chain is when motion, particularly when high engine load is moved, amplitude swing can occur, and timing chain cover and engine cylinder-body clash into easily, wear and tear.The chain tension rail of this patent adopts single plastic production to form, and is difficult to guarantee its wear resistance and tensioning dynamics.
Summary of the invention
The purpose of this utility model is the problems referred to above that exist for existing technology, and a kind of timing chain tension device of motor is provided, and technical problem to be solved in the utility model is to improve the stability of timing chain operation.
The purpose of this utility model can realize by following technical proposal: a kind of timing chain tension device of motor, this tension device comprises tensioning rail, it is characterized in that, the lean both side edges of face of described tensioning rail and timing chain is provided with and can alleviates the chain baffle plate that timing chain rocks, and described timing chain is through between the two chain baffle plates.
Tensioning rail arranges the chain baffle plate, the chain baffle plate is limited in timing chain between the two chain baffle plates and moves, the guidance capability of tensioning rail is just stronger like this, even when high engine load is moved, timing chain can not produce significantly yet and rock, with regard to having avoided timing chain to bump, wear and tear because rocking with timing chain cover and engine cylinder-body, make the timing chain operation more stable, longer service life like this.
In the timing chain tension device of above-mentioned a kind of motor, described tension device also comprises chain tightener, contact with the chain tightener both side edges at position of described tensioning rail has the chain tightener baffle plate, and described chain tightener comprises plunger, and described plunger is between two chain tightener baffle plates.During the motor operation, the chain tightener baffle plate can prevent effectively that plunger from rocking, and so just can make chain tightener remain on suitable state, and timing chain just is not easy to become flexible, and can reduce the number of times of adjusting chain tightener.
In the timing chain tension device of above-mentioned a kind of motor, described tensioning rail comprises outer panel and the side inner panel that leans with timing chain, have some buckles on the described outer panel, described side inner panel has the quantity draw-in groove identical with buckle, and described outer panel and side inner panel are assembled together by being connected of buckle and draw-in groove.Tensioning rail is divided into outer panel and side inner panel, is convenient to adopt different materials according to the difference in functionality of tensioning rail different parts, be conducive to prolong the whole service life of tensioning rail, also reduce the cost that the segment plate wearing and tearing are changed.Side inner panel and outer panel are by being clasped easy installation and removal.
In the timing chain tension device of above-mentioned a kind of motor, described side inner panel two ends have snap fit, and the two ends of described outer panel are embedded in the snap fit.So just having strengthened the join strength of side inner panel and outer panel, is that they are not easy mutual disengaging.
In the timing chain tension device of above-mentioned a kind of motor, described chain baffle plate and chain tightener baffle plate all are connected as a single entity with outer panel.
In the timing chain tension device of above-mentioned a kind of motor, described outer panel is made with material PA66-GF50, and described side inner panel is made with material PA66.PA66 is nylon 66 namely, and this material shock resistance is good, intensity is high, wear resistance good, can be good at tackling friction and the impact that timing chain produces side inner panel; PA66-GF50 is that its intensity is higher, can realize the tensioning of timing chain in the hightension situation at the glass fibre of the basis of PA66 adding 50%.
In the timing chain tension device of above-mentioned a kind of motor, described side inner panel is sandwiched between the two chain baffle plates.The chain baffle plate can also limit the transverse shifting of side inner panel, makes side inner panel be connected connection with outer panel more stable.
In the timing chain tension device of above-mentioned a kind of motor, described side inner panel lateral margin has flange, and the width of described chain baffle plate is greater than the height of flange.So just can timing chain be limited between the two chain baffle plates well.
In the timing chain tension device of above-mentioned a kind of motor, described chain baffle plate extends to part that timing chain and tensioning rail lean all between two chain baffle plates along corresponding lateral margin.So that timing chain is limited, make timing chain reach the most steady state on a large scale like this.
In the timing chain tension device of above-mentioned a kind of motor, the lean both side edges of part position of side of described tensioning rail and timing chain has the chain baffle plate.Easily rock or rock relatively severe position at timing chain the chain baffle plate is set, so just can reach stablize timing chain in saving material, weight reduction.
Compared with prior art, the utility model has increased chain baffle plate and chain tightener baffle plate at tensioning rail.The chain baffle plate makes the guidance capability of tensioning rail just stronger, even when high engine load is moved, timing chain can not produce significantly yet and rock, so just avoided timing chain to bump, wear and tear because rocking with timing chain cover and engine cylinder-body, make the timing chain operation more stable, longer service life; The chain tightener baffle plate makes timing chain be not easy to become flexible.Tensioning rail is divided into bi-material to be made, and has improved the adaptive capacity of tensioning rail, increases the service life, and reduces replacement cost.
