200420039065.9 the deficiency of technology is: driving engine and change speed gear box direct connection also are arranged in the top of drive axle, engine location is higher, weight is concentrated relatively, causes on the one hand that the tractor truck height dimension is big, center of gravity is higher, makes load be difficult to rectangular distribution again on the one hand.200420039064.4 the deficiency of technology is: adopt transmission shaft to be connected between driving engine and the change speed gear box, increased length dimension when reducing highly.
Because existing power drive exists driving engine and change speed gear box direct connection and is arranged in the top of drive axle, engine location is higher, weight is concentrated relatively, causes on the one hand that the tractor truck height dimension is big, center of gravity is higher, makes load be difficult to rectangular distribution again on the one hand; Adopt transmission shaft to be connected between driving engine and the change speed gear box, increased the deficiency of length dimension when reducing height, have significant limitation during use, it is even to satisfy the carrying of aircraft towing engine installation four-wheel, the requirement that center of gravity is low, length dimension is little.
Summary of the invention
In order to overcome the top that existing power drive exists driving engine and change speed gear box direct connection and is arranged in drive axle, engine location is higher, weight is concentrated relatively, causes on the one hand that the tractor truck height dimension is big, center of gravity is higher, makes load be difficult to rectangular distribution again on the one hand; Adopt transmission shaft to be connected between driving engine and the change speed gear box, increased the deficiency of length dimension when reducing height, the purpose of this utility model is to provide a kind of power drive of aircraft towing use, this device is taked driving engine and tor-con, change speed gear box is set up in parallel, driving engine is connected with coupler, coupler is connected with transfer trunk, transfer trunk is connected with tor-con, transfer trunk is by the transmission shaft input change speed gear box of two ends band universal-joint, driving engine reduction height is arranged in parallel near the body gravity with change speed gear box, satisfy the carrying of aircraft towing engine installation four-wheel evenly, center of gravity is low, the requirement that length dimension is little.
The technical scheme that the utility model technical solution problem is adopted is: a kind of Airtow power transmitting means, be provided with driving engine, change speed gear box, transmission shaft and vehicle bridge, and it is characterized in that: driving engine and change speed gear box, tor-con are set up in parallel; The flywheel of driving engine is connected with coupler, coupler is connected with transfer trunk, and transfer trunk is connected with tor-con, and tor-con is connected with last transmission shaft, last transmission shaft is connected with change speed gear box, change speed gear box by the forerunner after moving axis, rear drive shaft drive forwards bridge, rear driving axle outputting power respectively.
The two ends of last transmission shaft, drive axle, rear drive shaft are universal-joint, and middle is that castellated shaft is connected with spline housing and scalable adjusting.Driving engine is an intermediate arrangement, is arranged in the body gravity place.The power transmission of driving engine and change speed gear box is exported through the power conversion case.Arranged apart before and after tor-con and the change speed gear box, the middle transmission shaft that adopts connects.
The beneficial effects of the utility model are: owing to adopted driving engine and change speed gear box to be arranged in juxtaposition, reduced car body front and back size, reduced the car load height, it is even to reach distribution of load on distribution of load, and makes full use of the car body zone line, easy to maintenance.Solved the technical deficiency that center of gravity is higher, height dimension is excessive, increase power need increase height or increase length of aircraft towing power system configuration; Midship engine makes distribution of load more even, and the various pipelines of hydraulic efficiency pressure system, electric system are conveniently arranged and keeped in repair; Elastomeric coupler has reduced the impact of change speed gear box and the noise of operator's compartment.The utility model can be used for the aircraft towing transmission.
