The lower any equivalents done of essence or change, are regarded as belonging to protection domain of the present utility model.
As shown in figure 1, this utility model provides a kind of mobile concrete trucd mixer time sharing drive system, this biography
Dynamic system mainly include electromotor 1, fluid torque-converter 2, power transmission shaft, change speed gear box 4, mechanical clutch 5, clutch control handle 7,
Steer drive front-axle 6, steering drive back axle 8, clutch flexible axle 9, and wherein power transmission shaft has at three and uses, including total power transmission shaft
31, front propeller shaft 32, inter-axle shaft 33.
Specifically annexation is：Electromotor 1 is fixed on vehicle frame, and its delivery outlet is connected by flywheel with fluid torque-converter 2,
The outlet of fluid torque-converter 2 is connected by total power transmission shaft 31 with change speed gear box 4, and change speed gear box 4 is fixed on vehicle frame；The rear side of change speed gear box 4
It is connected with the connector of the front end of inter-axle shaft 33 by flange, inter-axle shaft 33 is again after the connector of rear end drives with steering
Bridge 8 connects, therefore the outfan of change speed gear box 4 drives the acquirement of back axle 8 to be connected by inter-axle shaft 33 with turning to；The front side of change speed gear box 4
It is bolted between flange on flange and mechanical clutch 5, the other end of mechanical clutch 5 is by flange and driving front
The connector connection of the rear end of axle 32, as shown in Figure 2；Front propeller shaft 32 is connected again by the connector of front end with steer drive front-axle 6
Connect, therefore the outfan of change speed gear box 4 is obtained with steer drive front-axle 6 by mechanical clutch 5 and front propeller shaft 32 and is connected；Machinery
A clutch flexible axle 9 is connected with clutch 5, the flexible axle other end is connected on clutch control handle 7, realizes vehicle traction
Power transmission and the cut-out of system.Forward and backward, front end specifically described herein, rear end, front side, rear side etc. are all according to car body front and back
Position definition.
In this utility model, mechanical clutch 5 is a critical component, and driving in conversion installed in realization for it serves pass
Key act on, as shown in Fig. 2 it be arranged between change speed gear box 4 and front propeller shaft 32, then can cut off or connect change speed gear box 4 with it is front
Driving-chain between power transmission shaft 32；If it is arranged between change speed gear box 4 and inter-axle shaft 33, change can be cut off or connected
Driving-chain between fast case 4 and inter-axle shaft 33.
System described in this utility model is the walking that the mode combined by hydraulic drive and machine driving controls vehicle,
Used as power source, timesharing converts the working method for driving and is electromotor 1：
1) when run into the big road surface of running resistance or it is very high to the off-the-road requirements of vehicle when, clutch control handss
Handle 7 is lifted and pulls clutch flexible axle 9 so that the two friction plates separation inside mechanical clutch 5, now, power passes through electromotor
1 exports to fluid torque-converter 2, and the power of fluid torque-converter 2 is delivered to change speed gear box 4 by total power transmission shaft 31, and change speed gear box 4 is to back axle
The part of transmission imparts power to turn to and drives back axle 8 by inter-axle shaft 33, is finally embodied in the walking of trailing wheel；Although
Change speed gear box also to front axle drive, but now change speed gear box 4 to the part of driving front be first delivered to mechanical clutch 5 when, by
Friction plate inside clutch is now in released state and (makes machinery by the pull-up clutch flexible axle 9 of clutch control handle 7
Friction plate inside clutch 5 is separated), mechanical clutch 5 is released state with front propeller shaft 32 and steer drive front-axle 6, because
This cannot continue to transmit power to propons, and power is cut off by the effect of clutch, can only realize the function of rear wheel drive.
2) when travelling on the preferable road surface of driving conditions, by driver's manual manipulation clutch control handle
7 so that handle is depressed, so as to pass through clutch flexible axle 9 so that the friction chip bonding inside mechanical clutch 5, now, power
When being exported to fluid torque-converter 2 by electromotor 1, the power of fluid torque-converter 2 is delivered to change speed gear box 4 by total power transmission shaft 31,
The part that change speed gear box 4 is driven backward imparts power to turn to and drives back axle 8 by inter-axle shaft 33, is finally embodied in trailing wheel
In walking；At the same time, because change speed gear box 4 is partially transferred to mechanical clutch 5 to driving front, and now clutch internal friction
Piece is in engagement state, so power will be passed to front propeller shaft 32 so as to continue to be passed to steer drive front-axle 6 by clutch
Graduating power, is finally embodied in that front-wheel is good to be gone on, to realize the function that four-wheel drives simultaneously.
Therefore, show as the characteristics of this utility model by the simple (general portion on vehicle of clutch control handle 7
Part) operation so that mechanical clutch 5 causes driving front so as to solve in engagement or detached state under different road conditions
Axle produces negative torque, the problem of engine power loss is caused so as to produce parasitic power so that behaviour of the vehicle in driver
The function of time sharing is realized under control, the power loss in the case of AWD is reduced, the work(of electromotor can be effectively played
Rate, improves engine power utilization rate.By above-described embodiment it can also be seen that, this utility model simple structure, flexible operation, plus
Work is easy to assembly, low cost.
Certainly above-described embodiment is that mechanical clutch 5 is arranged on the side being connected with steer drive front-axle 6, because
This can only limit propons driving, and this type is applied to back axle full working scope and drives vehicle.If conversely, complete for propons whole wheel drive car
, want to control rear bridge driven in some operating modes, mechanical clutch 5 can be arranged on drive back axle 8 to be connected with turning to completely
Side, now can control back axle work or do not work.So so-called time sharing is exactly, in different driving cycles
Under, the pattern that is operated alone of back axle or propons, or forward and backward bridge whole drive pattern can be individually opened, drive pattern exists
It is operated alone in front and back and converts between full drive pattern in front and back, time-sharing operation.
