Abstract
The utility model relates to a speed variator of running driving system of vibroll, which comprises a gear box and a speed reduction device. The input end of the speed reduction device is connected with one sub moving end of the sub moving device in the sub moving box in a transmission connecting manner. The output end of the speed reduction device and the input end of the gearbox are in a transmission connecting manner, and the output end of the gear box and the walking wheel are also in transmission connecting manner. The gear box is a power shifting gear box, and the speed changing control mechanism is a power shifting speed changing control mechanism transferred by the hydraulic pressure.
Description
The utility model relates to a kind of special vehicle, particularly a kind of vibratory roller walking driving system transmission system.
The used change speed gear box of vibratory roller walking driving system transmission system in the routine techniques, its gear shift, the maneuverability pattern that commutation is travelled is a mechanical type, promptly stir shifting slide gear and realize speed change with different gears mesh by shift fork, because vibratory roller operating mode and working environment are very special, its working process is accompanied by the high-frequency vibration that vibrating system brings, this continual high-frequency vibration is to gear shift, the maneuvering system of commutation has proposed very high requirement, facts have proved, traditional mechanical type operating control in use is easy to generate the trip stop phenomenon, even with this mechanical type operating control design, make enough meticulously, also be difficult to resist the influence that high-frequency vibration brings, usually after using one short period, still can produce the trip stop phenomenon.Simultaneously, the mechanical type operating control also exist intrinsic gear mesh process have some setbacks, handle weak points such as inconvenience.
The purpose of this utility model is to overcome weak point of the prior art, and a kind of control comfort is provided, and can not produce the vibratory roller walking driving system transmission system of trip stop phenomenon.
The purpose of this utility model realizes by following approach.
Vibratory roller walking driving system transmission system, comprise change speed gear box, its structural feature is: also include speed reduction gearing, one of them branch moved end of transfer device in speed reduction gearing input end and the auxiliary gear box is in transmission connection, speed reduction gearing mouth and change speed gear box input end are in transmission connection, gear box output end is connected with traction drive, and change speed gear box is a kind of Powershift transmission, and selector gear is a kind of hydraulicdriven power shfit selector gear.
Powershift transmission (also claiming the load shift change speed gear box) is a kind of routine techniques, is applied in usually on the heavy load vehicle, and it comes power between transmitter shaft and gear by several multi-disc friction clutches.When clutch engagement, gear that is connected with this clutch spindle and axle become one.When disengaging of clutch, gear becomes sky and is enclosed within on the axle, and it is disconnected from each other with axle, can not transferring power.Power-transfer clutch adopts hydraulic actuated, thus light than the mechanical type gearshift during gear shift, and satisfy the high requirement of heavy load vehicle to gear shift, speed change smoothness with this.The utility model this change speed gear box of migrating, be to solve high-frequency vibration that the vibratory roller working process followed to easy trip stop problem that selector gear brought, neither there is the working environment of high-frequency vibration in heavy load vehicle, generally can not produce the trip stop problem yet, therefore, compare with the technology of migrating, goal of the invention of the present utility model is all different with it with the invention effect, and, concrete technology constitutes also inequality, the utility model is compared the technology of migrating has increased speed reduction gearing, speed reduction gearing is installed in before the transmission system, not only can obtain final ideal velocity, and can reduce in the power shfit transmission system main by slowing down, between the driven fricting clutch plate initially from, fashionable velocity contrast is with effective minimizing master, from the wearing and tearing between the movable friction plate.
The purpose of this utility model can also realize by following approach.
Speed reduction gearing is installed in the auxiliary gear box.Compact form so more.
Speed reduction gearing is a kind of double-reduction gear device.
In sum, the utility model has following advantage compared to existing technology: effectively overcome the deficiency of mechanical gear shift change speed gear box, made the gear shift, reversing maneuver of vibratory roller running gear convenient, safety, reliably, can not produce " trip stop ".
Accompanying drawing 1 is the scheme drawing of vibratory roller walking driving system in the utility model most preferred embodiment.
Accompanying drawing 2 is auxiliary gear box driving system scheme drawings in the utility model most preferred embodiment.
Below in conjunction with accompanying drawing the utility model is carried out more detailed description.
Most preferred embodiment:
With reference to Fig. 1, vibratory roller walking driving system, its transmission system is made up of auxiliary gear box 2, first transmission shaft 4 and change speed gear box 8, auxiliary gear box 2 is connected by the clutch end of master clutch with diesel engine 1, auxiliary gear box 2 one mouths are in transmission connection with change speed gear box 8 by first transmission shaft 4, change speed gear box 8 mouths then are in transmission connection with drive axle 5 by second transmission shaft 6, finally drive road wheel 7 and travel.
With reference to Fig. 2, auxiliary gear box 2 comprises transfer device and speed reduction gearing, transfer device can be formed with the tooth embedding structure of transfer gear 22 clampings by the gear on the input shaft 21 and near axle head, speed reduction gearing is made up of one-level train of reduction gears 21,23, double- reduction gear group 24,25, and transfer gear 22 is with gear 26 engagements and drive vibratory pump 3 work; Driving dynamics output shaft 27 1 ends are sleeved in the input shaft 21 1 end endoporus by antifriction-bearing box, and like this, driving dynamics is through one-level train of reduction gears 21,23 and double- reduction gear group 24,25 and pass to driving dynamics output shaft 27.Here, gear on the input shaft 21 and tooth embedding structure are respectively two branch moved ends of transfer device.
The model of selected Powershift transmission is ZL30E, 5JA in the present embodiment, is a kind of commercially available prod, and its manufacturer is: Xuzhou Gear Factory.
It is same as the prior art that present embodiment is not stated portion.
