Abstract

FIELD OF THE INVENTION The invention relates to railway transport and relates to the construction of carriages for high power rail vehicles. The goal is to reduce weight, reduce the base, simplify the design when implementing a high value of the coefficient of gi. A locomotive multi-axle bogie consists of a rigid flat frame 1 made of longitudinal and transverse box-section girders with a symmetric arrangement of a pivot assembly and support-returning units relative to its center, wheel pairs 2, elastically connected with the frame by the leads 3 and spring suspension 4. Traction engines 5 with double-flow gearboxes 6 are located above the axles of the wheel pairs (with the vertical central line). The motors are rigidly fixed on the crossbeams of the frame, the gearboxes are flanged to the engine cores. The braking transmission of the carriage type is located in the cross-wheel space along the longitudinal axis of the carriage. The torque developed by the engines, through the gearbox 6 and the cardan drive containing the hollow shaft with plate clutches connecting it with the driven gear of the gearbox and the wheel wheel of the wheelset, is transmitted to the wheelsets 2. The symmetry of the frame and equipment located on it reduces the action of inertial forces and contributes to an increase in the coefficient of gi. The use of a vertical arrangement of the drive train allows to maximally bring together the wheel sets, as well as reduce the cross-section of the frame elements and reduce its weight. 3 il. i a C oc Cr C a a puz.

Description

This invention relates to railway transport and concerns the construction of carriages for a high-capacity rail vehicle.

It is not carried out by dampers of 17 oscillations.

The torque developed by the traction motors 5 is transmitted through the two Purpose of the invention - weight reduction 5 flow gearboxes 6 and cardan drives reduce the base, simplifying the design when implementing a high value of the thrust coefficient.

FIG. 1 shows the proposed trolley, side view; in fig. 2 - the same, top view; in fig. 3 is a section A-A in FIG. one.

The multi-axle bogie consists of a rigid frame I, which unites four wheel pairs 2, a spring elastically connected with the frame 10

mechanisms, each of which includes a hollow shaft 8 with plate couplings 9 and 10, one of which is connected to the driven gear of the gearbox, and the other with the wheel disk of wheel pair 2. The vertical load is perceived by four combined supports providing rotation and carts relative to the body, as well as in pairs balanced

the drive allows you to complete the frame of a simple box-shaped cart with maximum symmetry. Rigid fastening of engines to the frame beams makes it possible to obtain fasteners mounted on the adjacent 20 gauges, perceiving all types of loading and intermediate beams. Gearboxes 6 fixings with all frame elements, due to the enclosures on the engines, the bis frame is not directly connected. Torque is transmitted from the controller to the wheelsets through the hollow shaft 8 of the cardan drive through the plastic sleeves 9 and 10.
