Abstract
The utility model discloses a transmission system for an agricultural three-wheeled transportation vehicle, which is characterized in that a motor 1 is transversely arranged on a vehicle frame and is in V-shaped flexible coupling with the vehicle frame; transmission shafts 3 are respectively movably coupled with a connecting disk 2 and a connecting flange 41; the connecting disk 2 is fixedly coupled with a flywheel of the motor together; the connecting flange 41 is fixedly coupled with a clutch together. Because adopting the transmission system, the agricultural three-wheeled transportation vehicle has high transmission efficiency, good reliability and small vibration and noise.
Description
The utility model relates to the transmission system of transport vehicle, especially relates to the transmission system of agricultural with three-wheel transporter.
In the past, the three-wheeled farm transport vehicle type of drive mainly contained two kinds, i.e. belt-driving pattern and belt+chain gear pattern.The characteristics of belt-driving pattern: engine power vertically arrange and with the vehicle frame rigid attachment, driving engine is passed to connected rear axle by 3-4 root V-shape belt, drives wheel.Subject matter is that driving efficiency is low, and belt weares and teares easily, and the operator's compartment vibration is moving bigger, and traveling comfort is poor.The characteristics of belt+chain gear pattern: driving engine arranges that vertically with the vehicle frame rigid attachment, engine power is passed to power-transfer clutch and change speed gear box by belt, gives diff, back axle by chain gear again, and drive wheels.Subject matter is that the transmission system link is more, and driving efficiency is low and the chain noise is big, and belt and chain are consumable accessory, and the reliability of transmission system is reduced.
Goal of the invention of the present utility model provide a kind of driving efficiency height, good reliability, vibration and noise little be used for Power Train on the agricultural three-wheel transporter.
To achieve these goals, the utility model provides a kind of transmission system of agricultural three-wheel transporter, main by the single cylinder diesel engine that is installed on the vehicle frame, torque transfer, connected rear axle is formed, described connected rear axle is by power-transfer clutch, change speed gear box, diff, left and right sides semiaxis and drg are formed, described driving engine is connected with connected rear axle by torque transfer, its characteristics are that described driving engine is horizontally placed on the vehicle frame and connect with the vehicle frame V-type is flexible, described torque transfer is by terminal pad, transmission shaft and butt flange are formed, terminal pad, butt flange connects with transmission shaft employing activity, described terminal pad and engine flywheel are fixedly connected, and described butt flange and power-transfer clutch are fixedly connected.
Above-mentioned transmission system, its characteristics are that flexible connection of described V-type is by screw bolt and nut engine holding frame, pad and rubber damper and vehicle frame to be fixedly connected.
Above-mentioned transmission system, its characteristics are that the power take-off shaft of described change speed gear box is vertical with the takeoff output direction of principal axis of described diff.
Above-mentioned transmission system, its characteristics are that described terminal pad, butt flange adopt spider to connect with transmission shaft.
Above-mentioned transmission system, its characteristics are that the profile of tooth of the final reduction gear of described change speed gear box is helicon tooth or hyperbola profile of tooth.
Adopt the Power Train of said structure, realized the shaft drive of single cylinder diesel engine power, become driving engine and connect into V-type is flexible, greatly reduce the vibration and the noise of driving engine with the vehicle frame rigid attachment; In addition, driven off by shaft driving efficiency is obviously high and reliably good than chain-driving and belt-driving, and Transmission is not fragile.
Following structure accompanying drawing further specifies embodiment of the present utility model
Fig. 1 is a kind of shaft drive draw bail scheme drawing of agricultural three-wheel transporter
Fig. 2 is Figure 1A-A direction cutaway view
Fig. 3 is a kind of shaft drive agricultural three-wheel transporter connected rear axle structural representation
In Fig. 1, Fig. 2 and Fig. 3, an embodiment of the present utility model implements on a kind of single cylinder diesel engine three-wheeled farm transport vehicle.Its transmission system, mainly form by single cylinder diesel engine 1, flywheel 11, terminal pad 2, transmission shaft 3, butt flange 41, power-transfer clutch 4, change speed gear box 5, diff, left and right sides semiaxis and drg, single cylinder diesel engine 1 is horizontally placed on the vehicle frame, be fixedly connected with bolt, pad and rubber damper 7 and nut carriage and vehicle frame 6, thereby realized that single cylinder diesel engine 1 connects with the V-type of vehicle frame 6 is flexible single cylinder diesel engine 1.Flywheel 11 on terminal pad 2 and the single cylinder diesel engine 1 is fixedly connected, butt flange 41 is fixedly connected with power-transfer clutch 4, the two ends of transmission shaft 3 connect with terminal pad 2, butt flange 41 respectively, and connecting mode adopts spider to connect, thereby has realized shaft drive.The power take-off shaft 51 of change speed gear box 5 is vertical with power take-off shaft 53 directions of described diff.The final reduction gear 52 of change speed gear box 5 adopts the helicon gear or adopts hyperbolic gear, to realize commutation function.
After adopting above-mentioned embodiment, this three-wheeled farm transport vehicle has possessed following distinguishing feature:
1, adopts the shaft drive mode, improved driving efficiency and reliability thereof;
2, driving engine has realized that with vehicle frame the V-type supporting flexible is connected, and has reduced noise and vibration to a great extent, has improved ride comfort.
3, the most parts of later-model connected rear axle and existing connected rear axle can be general, and gear can adopt " 3+1 ", also can adopt " 4+1 ", and final reduction gear adopts screw bevel gear or hyperbolic gear, stable drive, reliable.
