Description
Technical field
Motor vehicle spare and accessory parts field is the utility model is related to, more particularly to a kind of bent axle of the external balance shaft of band.
Background technology
When piston often moves up and down once, engine will be made to produce two-time vibration one on the other, so the vibration of engine
Frequency is relevant with the rotating speed of engine.In Theory of Vibration, the vibration of engine is often described using multiple harmonic vibrations, wherein
Vibration frequency and engine speed identical vibrate single order, and frequency is that 2 times of engine speed is second order vibration, successively class
Push away, also vibrated in the presence of three ranks, quadravalence.But vibration frequency is higher, amplitude more than second order can be ignored with regard to smaller.Its single order
Vibration accounts for more than 70% entirely vibrated, is the main source of vibration.
What existing engine was commonly provided with is all the built-in balance shaft that can alleviate single order vibration, and built-in balance shaft can not
Second order vibration is balanced, its counterbalance effect is poor.
Utility model content
Based on this, the purpose of this utility model is, there is provided a kind of bent axle of the external balance shaft of band, it has structure simple
The advantages of list, good damping result, high stability.
A kind of bent axle of the external balance shaft of band, including connecting rod, left crank and right crank；The connecting rod passes through the crankpin
It is connected with the left crank and right crank, rotates and be arranged on a bearing of the crank pin respectively on the left crank and right crank；Also wrap
Balance shaft and a pair of balance gears are included, the balance shaft rotation is arranged at one couple of balance and held, and the pair of balance gear is nibbled
Connection is closed, the right crank is connected by the pair of balance gear with the balance shaft drive.
The bent axle of the external balance shaft of band of the present utility model is by setting external balance shaft by setting balance in outside
Axle, balance make single order vibration and the second order vibration of crank and right crank rotational band, alleviate the vibration of car body, add stabilization
Property.
Further, be arranged with a needle bearing on the crankpin, the connecting rod by the needle bearing with it is described
Bent axle pin connection.
Further, timing gears are provided with the middle part of the left crank.
Further, the free end of the left crank is provided with left woodruff key.
Further, right woodruff key is provided with the middle part of the right crank, one of them described balance gear passes through described
Right woodruff key is fixed on the right crank.
Further, the both ends of the balance shaft rotate and are arranged on the pair of equalizer bearing.
Further, it is provided with the middle part of the balance shaft for balancing the balance portion rotated.
Relative to prior art, the bent axle of the external balance shaft of band of the present utility model is by setting external balance shaft to pass through
Balance shaft is set in outside, and balance makees single order vibration and the second order vibration that crank and right crank rotational band are come, alleviates car body
Vibration, adds stability.The bent axle of the external balance shaft of band of the present utility model has simple in construction, good damping result, stably
The advantages that property is high.
In order to more fully understand and implement, the utility model is described in detail below in conjunction with the accompanying drawings.
Brief description of the drawings
Fig. 1 is the structural representation of the bent axle of the external balance shaft of band of the present utility model.
Embodiment
Referring to Fig. 1, the bent axle of the external balance shaft of band of the present utility model, including connecting rod 1, left crank 2 and right crank 3；

To on equalizer bearing 8, the pair of engagement of balance gear 7 connection, the right crank 3 passes through the pair of balance gear 7 and institute
Balance shaft 6 is stated to be connected.
Be arranged with a needle bearing 8 on the crankpin 5 of the present embodiment, the connecting rod 1 by the needle bearing 8 with
The crankpin 5 connects.
The middle part of the left crank 2 is provided with timing gears 9, and the free end of the left crank 2 is provided with left woodruff key 21.
The middle part of the right crank 3 is provided with right woodruff key 31, and one of them described balance gear 7 is fixed by the right woodruff key 31
On the right crank 3.
The both ends of the balance shaft 6 are rotated and are arranged on the pair of equalizer bearing 8, and the middle part of the balance shaft 6 is set
Have for balancing the balance portion 61 rotated.Balance shaft 6 is arranged on outside when mounted, need not thus take inner space, and
The vibration that brings when rotating of left crank 2 and right crank 3 is balanced by the rotation in balance portion 61, can alleviate single order vibration and
Second order vibration, good effectiveness in vibration suppression is played, increase stability, improve the comfortableness of driver.
Relative to prior art, the bent axle of the external balance shaft of band of the present utility model is by setting external balance shaft to pass through
Balance shaft is set in outside, and balance makees single order vibration and the second order vibration that crank and right crank rotational band are come, alleviates car body
Vibration, adds stability.The bent axle of the external balance shaft of band of the present utility model has simple in construction, good damping result, stably
The advantages that property is high.
Embodiment described above only expresses several embodiments of the present utility model, and its description is more specific and detailed,
But therefore it can not be interpreted as the limitation to utility model patent scope.It should be pointed out that the common skill for this area
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The scope of protection of the utility model.
