Abstract

The utility model relates to a passenger and freight car back car wheel which comprises an inner side rim, an outer side rim, an inner side tyre, an outer side tyre and a hub, an inner side spoke which is connected with the inner side rim to form a whole body and an outer side spoke which is connected with the outer side rim to form a whole body are fixedly connected with the hub through bolts, a half shaft is connected with the hub through a half shaft end cover, a cyclone plate is arranged at the outer end of the outer side rim and clings to the end surface of the outer side rim, a port of the outer side rim is covered, the cyclone plate is provided with an air inlet, and an orientation of the air inlet is consistent to a rotation direction of the passenger and freight car back car wheel in the forward running process. With the adoption of the passenger and freight car back car wheel, in the forward running process of a passenger and freight car, the half shaft, the hub and the spokes can be cooled.

Description

A kind of passenger and freight car rear wheel

Technical field

The utility model relates to automobile component, particularly the rear wheel of passenger and freight car.

Background technology

Consider that from heavy duty each side of the rear wheel of passenger and freight car is formed by inside and outside two wheels arranged side by side.Specifically; The passenger and freight car rear wheel comprises inboard wheel rim, outside wheel rim, inboard spoke, outside spoke, inside tire, outside tire and wheel hub, and inboard spoke and inboard wheel rim combine as a whole, and outside spoke and outside wheel rim combine as a whole; The medial and lateral spoke is fastenedly connected through bolt and wheel hub; Semiaxis is connected with wheel hub through the semiaxis end cap, and near the position of wheel rim, the edge circumferentially offers breather port on the spoke of medial and lateral.Passenger and freight car in the process of moving; The temperature of semiaxis, wheel hub and spoke is higher; Though it is outwardly open and outside being exposed to that wheel hub is positioned at wheel rim internal cause wheel rim port, because most air-flows can not get in the wheel rim, so make semiaxis, wheel hub and spoke can not obtain good cooling.

Summary of the invention

The purpose of the utility model provides a kind of passenger and freight car rear wheel, to overtake in the process, can make semiaxis, wheel hub and spoke obtain good cooling at passenger and freight car.

The said passenger and freight car rear wheel of the utility model; Comprise inboard wheel rim, outside wheel rim, inside tire, outside tire and wheel hub; The inboard spoke that combines as a whole with inboard wheel rim, the outside spoke that combines as a whole with outside wheel rim are fastenedly connected through bolt and wheel hub, and semiaxis is connected with wheel hub through the semiaxis end cap, is provided with the applying of cyclone plate and outside wheel rim end face in the outer end of off-side wheel rim; The ventilation inlet port is hidden; Cyclone plate is circular sheet metal component, offers ventilation inlet on it, ventilation inlet towards the hand of rotation in the process is consistent to overtake at vehicle with the passenger and freight car rear wheel

In the off-side wheel rim, be provided with mounting bracket, mounting bracket is fixed on semiaxis end cap or the outside spoke, and said cyclone plate is fixed on the mounting bracket, thereby makes cyclone plate on the passenger and freight car rear wheel, obtain secure fixation.

At passenger and freight car to overtake in the process; Since offer on the cyclone plate opening towards with the consistent ventilation inlet of passenger and freight car rear wheel hand of rotation; Air-flow will pour in the outside wheel rim of passenger and freight car rear wheel through ventilation inlet; And the breather port from the spoke of the outside flows out, and makes the air in the wheel rim of the outside be in the flow at high speed state, thereby the heat that semiaxis, wheel hub and spoke produce is taken away.

The said passenger and freight car rear wheel of the utility model is at passenger and freight car to overtake in the process; Because the air in the wheel rim of the outside is in the flow at high speed state all the time; Thereby the heat that semiaxis, wheel hub and spoke produce is taken away, so can make semiaxis, wheel hub and spoke obtain good cooling.

The specific embodiment

Like Fig. 1, Fig. 2 and shown in Figure 3; This passenger and freight car rear wheel is made up of inside and outside two wheels arranged side by side; Comprise inboard wheel rim 5, outside wheel rim 6, inboard spoke 11, outside spoke 9, inside tire 3, outside tire 1 and wheel hub 7, it be one that inboard spoke 11 joins 5 with inboard wheel rim, and outside spoke 9 and outside wheel rim 6 combine as a whole; Medial and lateral spoke 11,9 is fastenedly connected through bolt and wheel hub 7, and semiaxis 4 is connected with wheel hub 7 through semiaxis end cap 8.In off-side wheel rim 6, be provided with mounting bracket 12, mounting bracket 12 is fixed on the semiaxis end cap 8.Be provided with cyclone plate 2 in the outer end of off-side wheel rim 6 and fit with outside wheel rim 6 end faces, cyclone plate 2 is fixed on the mounting bracket 12, and wheel rim 6 ports in the outside are hidden.Like Fig. 4, Fig. 5 and shown in Figure 6; Cyclone plate 2 is circular sheet metal component, offers 13, eight ventilation inlets of eight ventilation inlets 13 with the mode of punching press on it and is evenly arranged on the cyclone plate 2 along circumferentially being radial; This ventilation inlet 13 is as the air louver on the metal case of some electric equipment; Ventilation inlet 13 towards the hand of rotation in the process is consistent to overtake at vehicle with the passenger and freight car rear wheel,, can air be poured in the wheel rim 6 of the outside from this ventilation inlet 13 to overtake in the process at vehicle.

Described mounting bracket 12 also can be fixed on the spoke 9 of the outside.
