Abstract
The utility model discloses a motorcycle engine rock arm type suspension damping device which comprises a bracket, a vehicle connecting frame and a cushioning bush. In this device, the outer end of the bracket which is used to suspend the engine is connected with the engine through a suspended axle and a bearing. The inner end is connected with the connecting frame of the vehicle frame through the bush. The cushioning casing is limited by the cushioning bush fixed on the vehicle frame. The other end of the connecting frame of the vehicle frame connects with the vehicle frame through the bush. The bracket and the connecting frame of the vehicle frame of the device can rotate relatively around the bush. A rock arm device which is altogether composed by the bracket and the connecting frame of the vehicle frame can rotate relatively around the bush of the connecting frame end of the vehicle frame and the engine suspended axle. The cushioning bush limit which is fixed on the vehicle frame has limitation function to its rotating. Thus the vibration of all directions produced by the running of the engine can be dispersed and transferred and then be absorbed by the cushioning bush.
Description
One, technical field
The utility model relates to a kind of motor bike hanging vibration reduction device, particularly a kind of driving engine is fixed on motor cycle engine rocker-arm hanging vibration reduction device on the vehicle frame.
Two, background technology
The hanging position of motor cycle engine and hang all have bigger influence to rigidity of frame, intensity, vibration etc.When driving engine being installed in the past, generally all be to pass the engine suspension hanger with bolt driving engine is fixed on the vehicle frame, at this moment, be in the state of being rigidly connected between the driving engine of motor bike and the vehicle frame, though this connection mode helps the raising of vehicle frame rigidity, but simultaneously the vibration that produces during engine running is directly passed to vehicle frame, cause the vibration of Finished Motorcycle of motorcycle, all can produce adverse influence to the traveling comfort of occupant's driving, the service life and the safety performance of motor bike, the noise that causes because of vibration simultaneously also pollutes to surrounding environment.Therefore, influence for the vibration that reduces driving engine, some motor bike manufacturers take to increase vibration damping gum cover supporting engine in the engine installation hanger, or between vehicle frame and driving engine, adopt simple link span and the combined connection mode of vibration damping gum cover, damping of vibrations has been played in these measures to a certain extent, but effect is still not ideal enough.
Three, summary of the invention
1, goal of the invention: for addressing the above problem, the utility model provides a kind of motor cycle engine rocker-arm hanging vibration reduction device that vibration is directly passed to can effectively reduce engine running the time vehicle frame.
2, summary of the invention: a kind of motor cycle engine rocker-arm hanging vibration reduction device described in the utility model, it is characterized in that: it comprises two supports that match, driving engine is hung axle, bearing, first bolt, first fixed hub, the first link span sleeve pipe, second bolt, second fixed hub, the second link span sleeve pipe, connecting panel, buffer ferrule and buffering lining, between the outer end of two supports, be fixed with driving engine and hang axle, hang a two ends at driving engine the bearing that is used to connect driving engine is installed, first bolt passes the inner end of two stands and first fixed hub between two stands, and the three fixed, outside first fixed hub, be with the rotating first link span sleeve pipe; Second bolt passes second fixed hub and is fixed on the vehicle frame, is with the rotating second link span sleeve pipe outside second fixed hub, and the second link span sleeve pipe is connected with the first link span sleeve pipe by connecting panel; Two stands roughly midway location be respectively equipped with buffer ferrule, buffer bush is installed in the buffer ferrule, an end of buffer bush is fixed on the vehicle frame.
Driving engine is hung axle and is fixed on two structures between the support outer end and can is: adopt the 3rd bolt to pass the through hole of support outer end and the driving engine between two supports and hang axle and the three is fixed.For the ease of regulating the installation site of driving engine, i.e. the position of the driving engine bearing hanging on the axle to be installed is hung at driving engine between the support of axle and both sides and is fixed with boss respectively.
In order to improve the rotating property between the rotatable parts, further improve the ability that absorbs vibration simultaneously, between first fixed hub and the first link span sleeve pipe, be provided with first loose bush, between first loose bush and the first link span sleeve pipe is flush fit, and is free-running fit between first fixed hub.This first loose bush can be provided in a side of the short lining made from two plastics at the first fixed hub two ends.
Based on same reason, between second fixed hub and the second link span sleeve pipe, be provided with second loose bush, be flush fit between second loose bush and the second link span sleeve pipe, and be free-running fit between second fixed hub.Second loose bush can be provided in a side of the short lining made from two plastics at the second fixed hub two ends.
Described buffer bush comprises inner covering and elasticity external bushing two parts, and the elasticity external bushing is enclosed within the outer rim of inner covering, and the 4th bolt passes inner covering one end of inner covering is fixed on the vehicle frame.Elasticity external bushing preferably cross sectional shape is the rubber bush of conical boss shape, its vibration damping, vibration absorption ability the best.
Principle of work: the outer end that is used to hang the support of driving engine hangs axle by driving engine and bearing links to each other with driving engine, the support inner end then links to each other with metal first fixed hub, and first loose bush that is made of plastics and be enclosed within the first link span sleeve pipe of its outer rim and first fixed hub between can rotate mutually; The version of second fixed hub, second loose bush and the second link span sleeve pipe as hereinbefore, just second fixed hub is to be fixed on the frame of motorcycle, the first link span sleeve pipe and the second link span sleeve pipe are fixed by connecting panel and are constituted a vehicle frame link span, in addition, the buffer bush that is enclosed within the buffer ferrule on the support is fixed on the vehicle frame equally.The support of this device can relatively rotate around the fixed hub that is connected them respectively with the vehicle frame link span, their common rocker arrangements of forming can relatively rotate around the bearing that fixed hub and driving engine are hung on the axle again, and the buffer bush that is fixed on the vehicle frame can rotate position-limiting action to these, the vibration of all directions that produce during like this by engine running all can be decomposed by this rocker structure and shifted and absorbed by buffer bush, thus reach reduce effectively vibration that driving engine produces to the transmission of vehicle frame, reduce the purpose of noise.
3, beneficial effect: the present invention compared with prior art, its remarkable advantage is: the vibration of all directions that produce during engine running all can be decomposed transfer by the rocker structure of being made up of described each parts, and absorb by buffer bush, thereby the vibration that has effectively reduced the driving engine generation has reached the purpose that reduces noise simultaneously to the vehicle frame transmission.Buffer bush is to be installed on the vehicle frame after passing buffer ferrule, and in the prior art cushion rubber is installed in the engine suspension hanger, cushion rubber must be subjected to the restriction of hanger size, position, then can arrange more suitable position on demand in the utility model, design more suitable dimension and select actv. material more.In addition, when re-engining or vehicle frame, only need be changed a little some size of each parts of the present utility model and can be fit to and different driving engines or vehicle frame connection, greatly reduce the difficulty and the cost of product improvement remodeling.The utility model is widely used in various motor cycle enginees.
