Description

A kind of built-in balance chain electromotor

Technical field

This utility model is related to a kind of built-in balance chain electromotor.

Background technology

Motorcycle engine is exactly to light the fuel mixture entering in cylinder to make its produced heat energy that burns be changed into Mechanical energy, and power is passed to by drive mechanism by motor cycle rear wheel from bent axle and is changed into the machinery of vehicle driving dynamics.

Existing built-in balanced engine is CG series, and air distribution system adds for helical teeth cam combination, lower shake-changing arm and push rod Formula structure, gear transmission noise is big, tooth vibrates big, multilevel transmission structure complexity easy break-down during being engaged, and foot steps on startup Foot is hindered in motivation resistance great Yi bounce-back.It is that helical teeth is driven and high-speed cruising is (at a high speed up to 11000r/ between bent axle and formal cam Min), helical teeth difficulty of processing is big, and casing crankshaft hole center is ensured with the position degree difficult processing at convex center-wheel arbor center, bent during assembling Axis helical teeth is extremely difficult with the fit clearance of cam helical teeth to be controlled and inefficiency.During operation, cylinder head noise is big, vibrate bigger than normal, foot The resistance of start is big.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of cylinder head noise little, and vibration is little, and the foot resistance of start is little Built-in balance chain electromotor.

For solving the above problems, this utility model adopts the following technical scheme that：

A kind of built-in balance chain electromotor, including cylinder body, bent axle, chain tooth, timing sprocket and chain, described chain tooth It is arranged on bent axle, described bent axle, chain tooth and timing sprocket be located at cylinder body, in cylinder head, described bent axle chain tooth and timing chain Wheel is connected by chain, and described timing sprocket one end is provided with cam, described cam connecting rocker arm, and described rocking arm connects valve, Gear ratio between described bent axle chain tooth and timing sprocket is 1: 2.

Preferably, the number of teeth of described chain tooth is 17-22.

Preferably, the number of teeth of described timing sprocket is 34-44.

Preferably, described chain is chip chain.

Preferably, the piece number of described chip chain is 5-9.

Preferably, described chip chain length saves for 96-106.

Preferably, described rocking arm includes into rocking arm and row's rocking arm, described valve includes inlet valve and exhaust valve.

The beneficial effects of the utility model are：The drive mechanism of bent axle to valve simply and is driven accurately, and centre did not had Many auxiliary work-piece transmissions decrease the probability that valve actuating mechanism breaks down.Overcome helical teeth between CG Series Crankshaft and timing cam The transmission big problem of resistance, thus foot is stepped on lighter during startup, also will not hinder foot because bounce is big.Little gram of chain drive noise Take CG Series Crankshaft and be driven the big problem of complicated noise to cylinder head.Chain drive engine luggine is little to be driven than CG Series Gear Vibration is significantly little and engine mildness is smooth.

Fig. 2 is a kind of left view perspective view of built-in balance chain electromotor of this utility model.

Specific embodiment

As depicted in figs. 1 and 2, a kind of built-in balance chain electromotor, including cylinder body 1, bent axle 2, chain tooth 3, timing chain Wheel 4 and chain 5, described chain tooth 3 is arranged on bent axle 2, and described bent axle 2, chain tooth 3 and timing sprocket 4 are located in cylinder body, institute State chain tooth 3 and timing sprocket 4 is connected by chain 5, described timing sprocket 4 one end is provided with cam 6, described cam 6 connects Rocking arm 7, described rocking arm 7 connects valve 8, and the gear ratio between described chain tooth and timing sprocket is 1: 2.

The number of teeth of described chain tooth 3 is 17-22.

The number of teeth of described timing sprocket 4 is 34-44.

Described chain 5 is chip chain.

The piece number of described chip chain is 5-9.

Described chip chain length saves for 96-106.

Described rocking arm 7 includes into rocking arm and row's rocking arm, and described valve 8 includes inlet valve and exhaust valve.

The above, specific embodiment only of the present utility model, but protection domain of the present utility model does not limit to In this, any change or replacement expected without creative work, all should cover within protection domain of the present utility model.
