Definitions
- the invention relates to a rail-bound electric traction vehicle, in which an electric traction motor lying parallel to the drive axle drives the latter by connecting the drive axle to the large wheel of a transmission, the pinion of which is connected via an elastic coupling, a cardan hollow shaft surrounding it and a further elastic coupling the rotor shaft is driven directly or via a further gearbox, with the traction motor suspended in the car body via the handlebars.
- Such a locomotive is known from DE-A-26 50 035.
- the oscillating suspension of the transverse drive motor consists in this known arrangement of three rigid links, which are arranged on both sides of the drive motor, and one articulation point on the car body and the other articulation point is arranged on an eye of the drive motor housing below the center line of the drive axis.
- the hinge points are designed as rubber-metal composite joints so that wear is avoided. Since the possible spring travel between the drive axle and the car body is very large, especially because the car body is dependent on the car weight, i.e. H.
- the diameter of the arranged between the pinion of the drive motor and the drive axle, the drive axle with play surrounding the hollow shaft is relatively large in the known traction vehicle in order to absorb all travel at all speeds.
- this has the disadvantage that the distance between the drive axle and the drive motor, i. H. the engine control center, is correspondingly large, so that difficulties in terms of ground clearance occur due to the large wheel that is also required.
- the invention has for its object to avoid these difficulties with an oscillating suspension of the transverse drive motor in the car body.
- a level control is accommodated in the handlebars of a traction vehicle of the type described in the invention. Small spring travel is then taken up by the cardan drive, while larger spring travel is compensated for by the level control.
- the diameter of the cardan hollow shaft can thereby be kept considerably smaller, so that there is enough space to accommodate a large-capacity traction motor for high driving speeds with a small motor center.
- the suspension of the traction motor in the vehicle body designed according to the invention can advantageously be used both with a single-axis drive with a cardan hollow shaft and with a single-axis drive with an intermediate gear and a cardan hollow shaft.
- the two individual masses of the traction motors are combined to form a total mass by the connection via the intermediate carrier. The behavior of this total mass in relation to shocks is more favorable because of the double inertia, which improves driving comfort.
- FIG. 1 shows, partially in section, a schematic plan view of the bogie of an electric locomotive, seen from below the car body.
- 2 shows a longitudinal section along the section line 11-11 in FIG. 1 and
- FIG. 3 also shows a section along the line 111-111 in FIG. 2, the pendulums lying behind the first driving axis not being shown.
- each drive axle 2 located within a bogie 1 are each driven by an electric drive motor arranged parallel to them.
- each drive axle 2 is connected via an elastic coupling formed by links, a cardan hollow shaft 5 surrounding the drive axle 2 with play and a further elastic coupling formed from a rubber ring spring 6 with a hollow shaft 7 surrounding the cardan hollow shaft 5, which carries the large gear (not shown) of a spur gear , in which the pinion of the drive motor 3 engages.
- the electric traction motors 3 of the two drive axles 2 located within the bogie 1 are rigidly connected to one another via an intermediate carrier 8.
- Both electric traction motors 3 are suspended via handlebars 9 in the body 10.
- Two links 9 engage between the driving axle 2 and the front of the bogie 1 lying with their lower pivot point 12 on the gear housing 13 below the center line of the driving axis 2, the other two links 9 lie on both sides of the drive motor 3 and engage with their lower pivot point 14 on the rigid intermediate support 8.
- each link 9 contains a level control 15. This can be designed pneumatically or hydraulically in a manner known per se.
- the level rain 15 balances the large spring travel possible between the body 10 and the drive motors 3.
- the cardan hollow shaft therefore only has to have a relatively small diameter because it has to absorb only relatively small spring travel.
- a link 16 from the traction motors 3 or from the intermediate carrier 8 to the bogie 1 is arranged horizontally on both sides.
