Description

The motor engine suspension gear

The engine suspension gear of the pedal-type motor bike (scooter) of the relevant a kind of novelty of the utility model refers to the motor engine suspension gear of holding mat suspension gear and vehicle frame to link together before a kind of engine especially.

The function of engine suspension gear is that engine and vehicle frame are directly combined.In order to absorb the vibration of engine, known structure often adds a rubber pad and reduces vibration.The motor bike of being produced in the market, its suspension gear is to withstand the frame reinforcement sheet with one or more rubber pads, one in front and one in back limits the start scope of entire mechanism, to guarantee that vibration that engine is produced reaches vehicle frame and minimizes.But this kind design can increase the difficulty of work in combination, and height of rubber washer also is hard to keep.Simultaneously, because of it need guarantee the micro-precompressed of rubber pad and reinforcing chip making on precision, assembling speed also so slower.Moreover the known overhung construction of this kind also can't prevent effectively that engine from making many connecting rods irregular movement.By the shortcoming and the problem of aforementioned every conventional construction, produced: how a kind of engine suspension gear that can simple and easyly assemble promptly is provided, can prevents that engine from making many connecting rods irregular movement, and make assembling speed also therefore very fast the demand of technique improvement in this respect.

Therefore, the main purpose of the utility model is to eliminate above-mentioned shortcoming, provide a kind of can simple and easy assembling and can prevent that engine from making the engine suspension gear of the pedal-type motor bike (scooter) of many connecting rods irregular movement.

According to motor engine suspension gear of the present utility model, it directly is attached on the vehicle frame, and suspention locks an engine in it down, includes:

One engine point of suspension is in order to lock to the hitch point of engine;

One bracing frame, it is to be connected to this engine point of suspension, and in order to lock this engine suspension gear on this vehicle frame;

It is characterized in that:

The a certain side of this bracing frame is provided with one first pipe, and a built-in rubber bush is in wherein, and is attached on one of this vehicle frame side; Another side at this bracing frame then is provided with second pipe of a built-in rubber bush and the 3rd pipe of a built-in elasticity start stop part, and lock this second pipe to another side of this vehicle frame, simultaneously, this second pipe and this first pipe constitute a centre of gration, make this engine suspension gear can do the trace rotation in view of the above, and the elasticity start stop part in the 3rd pipe can be used as the start scope of the whole engine suspension gear of restriction and the amount of compression of this elasticity start stop part is exactly little momentum of doing of entire mechanism.

Below in conjunction with accompanying drawing structure of the present utility model, characteristics and advantage are explained detailedly.

In the accompanying drawing

Fig. 1 is the block diagram of the engine suspension gear of known pedal-type motor bike (scooter).

Fig. 2 is the block diagram of the rubber bush that adopts of the utility model.

Fig. 3 is the scheme drawing of locomotive engine suspension gear main structure of the pedal-type motor bike (scooter) of the utility model.

Plan sketch when Fig. 4 is the engine suspension gear drl engine of the utility model and vehicle frame.

The engine suspension gear of known pedal-type motor bike (scooter) as shown in Figure 1, is that engine and vehicle frame are combined, and it is total system success or failure key in design with the shockproof effect.Suspension gear 10 is to withstand frame reinforcement sheet 12 with rubber 11, one in front and one in back limits the start scope of entire mechanism, to guarantee that vibration that engine is produced reaches vehicle frame and minimizes.This kind design need be guaranteed rubber and the precompressed of reinforcing chip trace on the making precision, assembling speed is therefore slower.

The utility model provides a kind of motor engine suspension gear of novelty, main system provides an integration rubber bush 20 of setting up for this engine suspension gear, the suspension gear main structure 30 that cooperates the utility model again is fixed on the frame reinforcement sheet engine, to replace rubber sheet gasket.Rubber bush 20 itself is to be formed by iron pipe and building rubber compound, so its shockproof effect is excellent.Aspect assembling, as long as lock on the frame reinforcement sheet with screw.Its purpose is to limit engine start scope, prevents that engine from making many connecting rods irregular movement.Whole suspension gear has good shockproof effect to the vibration of engine manufacturing, can reduce vibration and reach vehicle frame, and prevent that the rider from feeling under the weather because of vibration.

The engine suspension gear of the utility model is the engine and the vehicle frame combining mechanism of motor bike.This mechanism comprises integration rubber bush (Fig. 2) and main structure (Fig. 3) two major parts.The structure of integrating rubber bush as shown in Figure 2, skin be iron pipe 21, internal layer also is an iron pipe 23, the centre is with rubber 22 connections.Outer iron pipe 21 main functions are pressed in the main structure iron pipe for pressing to join.The iron pipe 23 of internal layer can lock screw, and as locating and supporting this main structure, intermediate rubber 22 can absorb the vibration that is caused by engine, makes the vibration that reaches vehicle frame reduce to minimum as far as possible.

As shown in Figure 3, suspention main structure 30 is by descending swing pipe 32, connecting strap 33, left and

right bracing frame

34,35 and go up connecting leg 36 to combine.Following swing pipe 32 is attached to the engine point of suspension with a long screw, and it is the centre of gration start that engine is put with this.Left and

right bracing frame

34,35 combines with iron plate and pipe, and there is a pipe 31 on the left side, the right have two pipes 31 ', 37, whole suspension gear with pipe 31,31 ' among the heart be centre of gration, do the trace rotation.Last connecting leg 36 is for connecting left and right both

sides bracing frame

34,35, and connecting leg 36 materials can be the iron pipe, with welding manner both

sides bracing frame

34,35 is combined into one, and the below links together with connecting strap 33 and following pipe 32, constitutes whole suspension gear.When assembling, pipe 31,31 ' in be press-fitted rubber bush 20, and with screw pass through pipe 31,31 ', lock respectively on the and arranged on left and right sides of vehicle frame 41, swing pipe 32 is then in order to locking the point of suspension to engine, and makes engine be the centre of gration start by this point.One of principal character of the utility model promptly is to set up a rubber bush 20 in pipe 37, as the usefulness of further shock-absorbing and restriction start scope.Because the engine suspension gear of the utility model system directly is locked on the vehicle frame, establish a rubber bush 20 can be reached shock-absorbing and restriction start scope simultaneously in pipe 37 effect, and the assembling of integral body is also more simple effectively.

The combination view of engine 43 and vehicle frame 41 as shown in Figure 4, when rear shock absorber 42 was compressed, engine 43 following pipes 32 were for the center rotates, and then with pipe 31,31 ' be the center, work is micro-to be rotated suspension gear 30.But 37 restriction systems in center are made momentum, and its inner rubber amount of compression little momentum of doing that is exactly total system.

Though explain orally the feature and the advantage of the utility model with reference to above-mentioned preferred embodiment, be not to separate the protection domain that limits the utility model in fact with these.Ripe personage in this skill can be that various variations and modification are done in aforementioned preferred embodiment according to the attached claims in back, and this kind changes and modification must be regarded as in the scope of patent protection that the utility model is asked.
