Description

A kind of guider of the sky rail bogie of car

Technical field

A kind of guider of the empty rail bogie of car is the utility model is related to, for the empty rail bogie of car, belongs to machine Car technical field.

Background technology

Empty rail vehicle is a kind of suspension type monorail city railway train, the guider of its bogie should can be real well The now running guiding of the suspension type rail bogie of car and stabilization.

At home, the research and development of suspended rail vehicle are still in the starting stage.

Utility model content

The goal of the invention of the utility model is：For above-mentioned problem, there is provided a kind of sky rail bogie of car Guider.

The technical solution adopted in the utility model is such：

A kind of guider of the sky rail bogie of car, including guiding axis, wheel hub, directive wheel and guide sleeve, the guiding Axis is arranged in guide sleeve by a pair of of taper roll bearing vertical rotating, the taper roll bearing outer ring and inner ring under it is upper End face is born against on the ladder end face of guide sleeve endoporus and guiding axis, the lower face of inner ring by the baffle ring on guiding axis, Packing ring and nut realize axial restraint, are resisted against in upper tapered roller bearing internal ring upper surface on the ladder end face of guiding axis, Outer ring lower face is resisted against on the ladder end face of guide sleeve endoporus, and guiding axis upper end stretches out guide sleeve and detachable connection wheel Hub and directive wheel.

Above-mentioned technical proposal utilizes the technologies such as the ladder end face of guiding axis, the ladder end face of guide sleeve endoporus, bearing, nut Feature carries out guiding axis axial restraint, and no matter this guider is positive installation or reverse mounted, is not all influenced.

Preferably, a sealing ring is set between baffle ring and guide sleeve endoporus, above upper taper roll bearing A sealing ring is socketed also on guiding axis.

The effect of sealing ring is to form a clean closed environment, prevents dust from entering, bearing is protected, prolong Its long service life.

Preferably, the directive wheel is divided into the inner ring of metal material manufacture and the outer ring of elastomeric material manufacture.It will be oriented to Wheel is divided into inner ring and outer ring, when serious wear needs replacing maintenance, outer ring is only needed to change, so as to effectively save expense.

Preferably, the wheel hub is socketed on guiding axis, medial surface is resisted against on ladder end face, and lateral surface passes through locking Nut check.

Preferably, detachable connection is realized by bolt between the directive wheel and wheel hub.

In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are：

1st, either positive installation or it is reverse mounted can, therefore can be installed on empty rail bogie of car top and The side of lower part, realizes the guiding and stabilization of empty rail vehicle；

2nd, whole guider is simple in structure and compact, adapts to working environment narrow and small in sky rail；

3rd, it is detachable connection between directive wheel, wheel hub and guiding axis, easy to change and safeguard.

Embodiment

Below in conjunction with the accompanying drawings, the utility model is described in detail.

Embodiment：

As shown in Fig. 2, a kind of guider of the sky rail bogie of car, including guiding axis 31, wheel hub 37,38 and of directive wheel Guide sleeve 39, the guiding axis 31 are arranged in guide sleeve 39 by a pair of of 35 vertical rotating of taper roll bearing, the circle under 35 outer ring of taper roller bearing and the upper surface of inner ring are born against on the ladder end face of 39 endoporus of guide sleeve and guiding axis 31, interior Axial restraint is realized in the lower face of circle by the baffle ring 34 on guiding axis 31, packing ring 33 and nut 32, in upper taper roller axis Hold 35 inner ring upper surfaces to be resisted against on the ladder end face of guiding axis 31, outer ring lower face is resisted against the stepped end of 39 endoporus of guide sleeve On face, 31 upper end of guiding axis stretches out guide sleeve 39 and detachable connection wheel hub 37 and directive wheel 38.

One sealing ring 36 is set between 39 endoporus of baffle ring 34 and guide sleeve, above upper taper roll bearing 35 also A sealing ring 36 is socketed on guiding axis 31.

The directive wheel 38 divides the inner ring for metal material manufacture and the outer ring of elastomeric material manufacture.

The wheel hub 37 is socketed on guiding axis 31, and medial surface is resisted against on ladder end face, and lateral surface passes through locking nut Locking.
