chen, consisting of a framework and a one provided with wheels and a structure equipped as load hollow handles for pulling and pushing the same. Such vehicles are used in particular in the road cleaning service, so that the necessary tool, like broom, shovel, scratches etc. are constant, to the hand and furthermore a load hollow is available for wastes and Kehricht. The available invention placed itself to the task to improve such vehicles which can be used particularly for the cleaning service with traffic surfaces both handling-moderately and effect-moderately substantially. This succeeds according to invention by the arrangement of an insertable, drive by electric motors and an adjustable and if necessary ascertainable Bremsvorrichtung. In many ranges for persons and materials handlings electric vehicles are in use. The usual advantages of such vehicles are to a large extent admit (exhaust-free, noiselessly, simply in the operation and maintenance). From the multiplicity of the electric vehicles offered today particularly those became generally accepted, which were designed particularly for a certain area of application. This was thus reached straight by the available invention. The vehicle can be pushed both händisch or pulled or it can also a drive by electric motors be connected, if larger loads are present or are a larger upward gradient to be overcome. The work of the employment personnel is substantially facilitated thereby. The employment personnel can connect the drive by electric motors after own discretion or move the vehicle however by hand. Furthermore it is suggested that the drive by electric motors with two wheels of the framework is domable and at the framework at least a further, a guidable and preferably not propelled wheel is arranged. Thus an optimal power transmission of the drive to the underground is made possible, in addition, permitted a perfect steering element on closest area. It can take place thus a rotation practically on the place as before with the two-wheeler hand cars. Furthermore the balance is to be held for no more as with the past two-wheeler hand cars. It is void thus also raising and setting the vehicle off. Naturally the operation smoothness is still improvable, as the possibility exists now to use wheels running in ball bearings and supplied with pneumatic tires. In order to make a perfect handling possible of the vehicle both for the hand enterprise and with the employment with a drive by electric motors, it is suggested that handles as is trained guidance handle, which is bringable with the Bremsvorrichtung and with a switching mechanism for the drive by electric motors in effect connection at the same time. It knows with for the hand enterprise the planned handles thus direct also the controlling and/or circuit of the drive and also the Bremsvorrichtung to be made. In this connection it is meaningful, if as guidance handle the trained handles with an interruption switch for the electric circuit of the drive in effect connection stands. It can thus by simply releasing handles the drive by electric motors to be switched off. If additionally it is then still planned that as guidance handle the trained handles at the same time with the interruption switch for the electric circuit of the drive and with the Bremsvorrichtung in effect connection stands, then by simply releasing handles switched off the drive by electric motors and uses the Bremsvorrichtung directly. Like that also a large security and the avoidance of accidents are possible. An arrangement is furthermore favourable, with which a for example three speed main switch is assigned to the drive by electric motors. Thereby several speed ranges of the drive by electric motors can be preselected clearly and easily recognizably. An optimal function is ensured by the fact that the main switch and the interruption switch are located with one another in effect connection. Thus the possibility is creative that probably pre-setable is switched on the drive the by electric motors that the current supply handles however however only when closing the interruption switch, thus with low pressure as guidance handle the trained, becomes effective. A further design detail lies in the fact that the braking force of the Bremsvorrichtung is adjustable. Thus the necessary braking force can be stopped to the given situation. Straight one in this connection is favourable it, if the Bremsvorrichtung is applicable both with hand enterprise and with the employment of the drive by electric motors also during the movement of the vehicle. Thus for example additionally also into action with work on one easily or strongly the Bremsvorrichtung can go and thus to the accident prevention contribute dropping road. An optimal possibility for the current supply of the drive is seen in the fact that at the framework batteries are arranged for the supply of the drive by electric motors. It is ensured thereby also a pollution free construction. The employment of a 12-Volt-Gei-Trockenbatterie is favourable in this connection. So that also with a simple construction and a good effectiveness of the drive for the vehicle can be attained, it is suggested that the wheels are connected with the drive by electric motors by a differential gearing, chain wheels and link chains. Thus simple constructional means are assigned, which besides essentially maintenance-free and are störungsunanfällig despite the constant dust load. A meaningful construction is seen in the fact that the drive by electric motors is integrated in the housing taking up the differential gearing. Thereby also the space requirement can be kept accordingly small. Also the weight question places itself naturally with vehicles which can be moved also by hand. Straight one by the measures according to invention can be created here an optimal solution. Further characteristics according to invention and special advantages are still more near described in the following description on the basis the designs. Show: Fig. 1 a side view of the vehicle; Fig. 2 a plan view on the vehicle; Fig. 3 a front view from the operating side of the vehicle; Fig. 4 a cut after the line Iv-lV in Fig. 2; Fig. 5 an opinion of the subrange of the vehicle from above in direction of arrow V in Fig. 4; Fig. 6 a cut after the line Vl-Vl in Fig. 2; Fig. 7 an opinion of the subrange of the vehicle from above in direction of arrow V in Fig. 6. With in the designs represented vehicle for the cleaning service of traffic surfaces is a structure 4 provided framework 5 and one equipped with wheels 1, 2 and 3 and one for example as load hollow handles 6 for pulling and pushing the vehicle 17. The substantial characteristics at this vehicle lie in the arrangement of an insertable, drive by electric motors 7 and a if necessary ascertainable Bremsvorrichtung 8. The drive by electric motors 7 is domable with the two wheels 1 and 2 of the framework 5. At the framework 5 at least a further, guidable and preferably not propelled wheel 3 is arranged. Both as the propelable wheels 1 and 2 and the wheel 3 planned for steering element can be implemented aluminum wheels with spokes. In the wheel hubs of the propelled wheels 1 and 2 block brakes are inserted or alternatively - if hydraulic disc brakes are used - brake disks installs. The framework 5 can be formed for example from LeichtprofiI Formrohren. On the operating side of the vehicle 17 a plate 9 can be developed, on which the Bremsvorrichtung 8 also handles and 6 is installed. Those handles 6 is trained as guidance handle, which is bringable at the same time with the Bremsvorrichtung 8 and with a switching mechanism for the drive by electric motors in effect connection. The drive by electric motors 7 is connected by a differential gearing 10, chain wheels 11 and 12 as well as link chains 13 with the wheels 1 and 2. The drive 7 is favourably in the differential gearing 10 integrated. As power source a 12-Volt-GelTrockenbatterie serves 14, which can be fastened for example in a guard to the plate 9 implemented as framework plate. By the arrangement of the battery in a guard this is impact-secured accommodated wetterund. The drive 7 is over a three speed main switch 15 to be switched on. Depending upon choice of the stages for example a driving speed is reached by two, four or six StundenkiIometern. By an interruption switch 16 the drive 7 is switched off, an integrated electromagnetic clutch remains however in function. When switching the main switch off the drive axles are switched to free-wheel. With as guidance handles the implemented handles 6 several functions are made possible. Those handles for pushing or pulling and for steering the vehicle 17 is used. On the right side 6 is installed a prop 18 with a brake discharge 19 handles. On the left side a prop 20 with 16 is inserted to an attack 22 and the interruption switch. In the hand enterprise the brake is with more depressed handles 6 exonerative. When releasing 6 the vehicle 17 handles by effect of a tension spring 23 is fully in-braked. When connecting the drive by electric motors 7 the main switch 15 is switched on. Now handles 6 depressed, the interruption switch 16 closes the current circle and the vehicle 17 is put with relieved brakes into operation. When releasing the electric circuit handles 6 by the discharge of the interruption switch again is interrupted and the vehicle again fully in-braked. The braking action can be stopped through tricks of a link body 24 depending upon area and transportation load more strongly or more weakly. On roads with downward gradient the brake load can - in particular with hand enterprise. thus to be adjusted that the vehicle 17 handles 6 with more depressed also depending upon downward gradient and load remains such in-braked that a desired driving speed without händisches holding back can be kept. In the case of use of the drive by electric motors 7 on roads with downward gradient the driving speed is regulated after adjusted stage of the main switch 15 automatically, probably used in the majority of the employments (depending upon area) the hand enterprise. Only with heavy loads or on roads with upward gradients, e.g. also with underpasses or transfers, the drive by electric motors 7 is switched on. This makes possible also the use of smaller batteries with according to fewer weights, since the assignment is shortened. The Bremsseile or appropriate pressure oil hoses on use of hydraulic brakes and the Stromkabel are fastened appropriately in sleeves to the form pipes of the framework 5 or are into the form pipes of the framework 5 moved. The structure 4 implemented as load hollow can likewise be manufactured from aluminum plate with reinforcement grooves. Further also one can be planned mechanically or hydraulically working tilting device. The vehicle 17 can be equipped also with an electrical lighting 25, which independently of the main switch 15 directly of the battery 14 over a light switch 26 in enterprise can be taken. With the measures according to invention straight for a special area of application can become a vehicle creative, which is optimally effective both for the hand enterprise and with employment of the drive by electric motors and represents a substantial relief for the operating personnel. In the context of the invention various constructional details can be solved in different way, without leaving the basic concept of the available invention. A further important objective with the vehicle according to invention was the reaching of a small total weight as well as a simple operation possibility. Beyond that special value is put on an execution in terms of safety, so that also to the accident prevention can be contributed. Under adherence to these targets it is also reached that a low-priced vehicle can be created, which can be used in smaller municipalities or enterprises economically justifiablely.
