Abstract
The utility model relates to a locomotive traction pin device, which comprises a traction shaft (1). The utility model is characterized in that a traction block (3) made of MC nylon materials is directly sleeved at the bottom end of the traction shaft (1), and pressure plates (4) fixedly connected with the traction shaft (1) are disposed on the bottom end surfaces of the traction shaft (1) and the traction block (3). Compared with the prior art, the locomotive traction pin device has the advantages of few parts, light weight, simple overall structure, simple processing, easy installation, good self-lubrication effect and low manufacturing costs.
Description
Technical field
The utility model relates to a kind of locomotive traction pin assembly.
Background technology
Bogie truck on the locomotive is divided into two kinds of forms, and a kind of is two-axis, and another kind is a triple axle.The mode of traction of the bogie truck of diaxon all is the structure that adopts towing pin usually; comprise axis of traction; bottom at axis of traction is with lining; outside lining, be with nyliner; be with guiding piece outside nyliner, guiding piece is positioned at the traction frame inboard, during work; the radical function of guiding piece is whole tractive forces and a braking force of bearing locomotive, bears the impact that locomotive operation causes.The towing pin device shortcoming of existing this structure is: complex structure, processing difficulties and weight are very big, and total mass is generally more than 253 kilograms, and the number of parts of whole device reaches more than 20, the manufacturing cost height.
Summary of the invention
The purpose of this utility model provides that a kind of part is few, in light weight, integral structure is simple, good processing, easily install, locomotive traction pin assembly that self-lubricating effect is good, overcome the deficiencies in the prior art.
Locomotive traction pin assembly of the present utility model, it comprises axis of traction 1, it is characterized in that: directly be set with the guiding piece 3 of MC nylon material in the bottom of axis of traction 1, be provided with the pressing plate 4 of captiveing joint with axis of traction 1 at the bottom face place of axis of traction 1 and guiding piece 3.
Locomotive traction pin assembly of the present utility model is provided with backstop 2 between the pillow block of the upper surface of described guiding piece 3 and axis of traction 1.
Locomotive traction pin assembly of the present utility model, the described bolt that is fixedly connected as connects.
Locomotive traction pin assembly of the present utility model has compared with prior art that part is few, in light weight, the simple advantage of integral structure, good processing, easily install, self-lubricating effect is good, low cost of manufacture.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment;
Fig. 2 is the main cross-sectional schematic of guiding piece;
Fig. 3 is a schematic top plan view shown in Figure 2.
The specific embodiment
As shown in Figure 1, 2, 3: 1 is axis of traction, is processed with pillow block in the bottom of axis of traction 1, and is set with backstop 2, and backstop 2 leans against the pillow block place.Guiding piece 3 directly is sleeved on the bottom axle of axis of traction 1, is provided with pressing plate 4 at the bottom face place of axis of traction 1 and guiding piece 3, and with at least two bolts 5 pressing plate 4 is fixed on the termination of axis of traction 1, is used for the guiding piece axial limiting.In order to prevent to come off, on the end cap of each bolt 5 processing porose, and in the hole, be installed with steel wire 6, overcome the revolution of bolt 5, to guarantee the fixing of pressing plate 4.Be processed with groove 7 on the endoporus side of guiding piece 3, the material of guiding piece 3 is the MC nylon that self-lubricating effect is good and machinability is good.
Claims (3)
