Abstract
The utility model relates to a shunting locomotive, in particular to a shunting locomotive based on a double-shaft extension direct current traction electric motor, which solves the problems of higher cost and complicated installation structure caused by the motor installation mode adopted by an existing shunting locomotive. The shunting locomotive comprises a traction motor, wherein the traction motor is a double-shaft extension direct current traction electric motor, and the arrangement direction of the double-shaft extension direct current traction electric motor is perpendicular to a wheel shaft of the locomotive, motor shafts on two ends of the double-shaft extension direct current traction electric motor are respectively connected with the power input shafts of reduction boxes on two side locomotive wheel shafts through couplings. Bracket bottom plates are symmetrically welded on the upper portion of the casing of the double-shaft extension direct current traction electric motor along the axial direction, a plurality of support reinforcing plates are arranged between the lower surfaces of the bracket bottom plates and the casing in equal distance along the axial direction of the electric motor, and fixed through-holes are arranged between two support reinforcing plates on the bracket bottom plate. The shunting locomotive has simple and reasonable structure, low cost and excellent economic benefits and applicability.
Description
Technical field
The utility model relates to a kind of shunting locomotive, specifically is a kind of shunting locomotive that stretches the stream traction motor based on twin shaft.
Background technology
At present, traction motor generally all is to adopt to roll to embrace or the sliding suspended structure of embracing vertically is installed on the bogie truck of locomotive; Vertical mounting means of certain locomotive traction motor as shown in Figure 1: 6 (1D, 2D, 3D, 4D, 5D, 6D) traction motors vertically are installed on the bogie truck 11 of locomotive, and the locomotive tractive effort is 6 times an every tractive force; When several electrical motor parallel operations, in order to help alleviating the degree of utilization that locomotive axle when moving heavily shifted and improved locomotive adhesive weight, the motor reversed arrangement of two bogie trucks before and after the locomotive, if promptly forecarriage is for just changeing, and the motor of another bogie truck is for reversing.Hauling engine is divided into main-line locomotive and shunting locomotive according to operating range, wherein, shunting locomotive is mainly used in the short range traction, every performance does not have the requirement height of main-line locomotive, therefore, at present with a plurality of traction motors vertically install, the mounting means of parallel operation is for shunting locomotive, mounting structure complexity not only, and cost is higher.
Summary of the invention
The utility model provides a kind of shunting locomotive that stretches the stream traction motor based on twin shaft for the electrical installation that solves existing shunting locomotive employing causes problems such as the shunting locomotive cost is higher, mounting structure complexity.
The utility model is to adopt following technical scheme to realize: the shunting locomotive that stretches the stream traction motor based on twin shaft, comprise the traction motor that is fixed in shunting locomotive truck frame/vehicle frame underframe below, described traction motor is that twin shaft stretches the stream traction motor, and what twin shaft stretched the stream traction motor is provided with direction vertical with locomotive axle (being that twin shaft stretches stream traction motor crosswise fixed below shunting locomotive), twin shaft stretch flow the traction motor two ends motor shaft respectively the power input shaft of the drop-gear box on plunging joint and both sides locomotive axle be connected.
Described twin shaft stretches the intrinsic base-plate that is provided with along the electrical motor axial direction of casing top balanced welding of stream traction motor, along electrical motor axial direction spaced set several bearing ribs are arranged between base-plate lower surface and the casing, offer between two bearing ribs on the base-plate and be used for carrying out the fixed via of bolt with shunting locomotive truck frame/vehicle frame underframe.
Compared with prior art, the utility model is laterally installed twin shaft and is stretched the stream traction motor, by the bilateral transmission of the plunging joint at two ends, drives locomotive operation, when reaching shunting locomotive running under power, installation requirement, reached the purpose that reduces design and manufacturing cost; Simultaneously, mount fixing structure is different to be embraced and the sliding suspended structure of embracing with rolling in the past, adopts and hangs mounting structure, easy for installation, has general applicability on shunting locomotive.
The utility model is simple and reasonable for structure, and cost is low, has good economic benefit and applicability.
