The utility model provides a highway-railway dual-purpose wheel set device, adopts hydraulic motor drive walking wheel structure, compares motor drive, and the driving force is strong, can stepless speed regulation, and brake performance is better; the H-shaped wheel set is adopted, the wheel set can be controlled to switch without an electric control system or a hydraulic system, and the vehicle can walk on a front track and a flat road surface.
Description
Technical Field
The utility model relates to an urban rail transit technical field is a dual-purpose wheelset device of highway-railway particularly.
Background
At present, in urban rail transit engineering in China, a road and railway dual-purpose equipment running wheel set generally adopts a single wheel set or double wheel set structure. The single wheel group structure adopts steel wheels or tires and can only adapt to the straight track or the flat ground; the function is single, simple structure, and the wheelset is changed complicacy. The double-wheel set structure adopts two sets of running systems of steel wheels and tires, and can realize running operation on a front track and a flat road surface by switching wheel sets; the system has complex structure, slow auxiliary switching and large size of the whole machine.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to solve prior art's not enough, provide a novel dual-purpose wheelset structure of urban rail transit highway and railway, can be applicable to simultaneously the line track of the straight line and the capable operation of walking on the road surface on the peaceful ground, can be used for urban rail construction under the multiple operating mode to equip, simple structure, the wheelset switches more conveniently.
In order to achieve the purpose, the road and railway dual-purpose wheel set device comprises an H-shaped wheel set consisting of a steel wheel and two outer wheels, wherein the H-shaped wheel set is arranged in a bilateral symmetry mode by taking the steel wheel as a center, and the two sides of the steel wheel are provided with wheel rims; and the hydraulic motor is connected and arranged on the clamping plate inside the steel wheel through a bolt, and the other end of the hydraulic motor is fixedly arranged with the wheel shaft.
The utility model discloses still have following preferred technical scheme:
furthermore, the outer wheel adopts a track walking wheel structure, and a rubber wheel sleeve is bonded on the rim of the outer wheel.
Furthermore, the H-shaped wheel set is connected with the wheel shaft through a flange at the end part of the hydraulic motor and is connected with the equipment frame through the mounting base, and the hydraulic motor drives the steel wheel, the outer wheel and the rubber wheel sleeve to rotate.
Beneficial effects of the utility model
The utility model provides an advantage of dual-purpose wheelset device of highway-railway includes but is not limited to:
1. the hydraulic motor is adopted to drive the traveling wheel structure, and compared with motor driving, the driving capability is strong, stepless speed regulation can be realized, and the braking performance is better.
2. The H-shaped wheel set is adopted, the wheel set can be controlled to switch without an electric control system or a hydraulic system, and the vehicle can walk on a front track and a flat road surface.
Drawings
Fig. 1 is a schematic perspective view illustrating a dual-purpose wheel set device for highway and railway according to the present invention;
fig. 2 is an exploded schematic view of an H-shaped wheel set of a road-rail dual-purpose wheel set device according to the present invention;
in the figure: 1. the highway-railway dual-purpose H-shaped wheel set 2, the vehicle frame 3, the mounting base 4, the wheel shaft 11, the outer wheel 12, the steel wheel 13, the rubber wheel sleeve 14 and the hydraulic motor.
Detailed Description
The technical solutions adopted by the present invention are further explained below by means of drawings and examples to help those skilled in the art to better understand the technical solutions adopted by the present invention.
Referring to fig. 1, the utility model discloses a dual-purpose wheelset device of public railway includes H type wheelset, H type wheelset 1 refers to fig. 2, mainly includes steel wheel 12, foreign steamer 11, rubber wheel cover 13, hydraulic motor 14 and constitutes. The two sides of the steel wheel 12 are provided with wheel rims, so that the equipment is prevented from falling off the main track when the equipment travels on the main track; the outer wheel 11 is in accordance with a common track running wheel structure, and a rubber wheel sleeve 13 is bonded on the wheel rim of the outer wheel 11 in order to ensure the running capability on a flat road surface. The integral structure of H type wheelset uses steel wheel 12 to arrange as central bilateral symmetry, passes through bolted connection installation foreign steamer 11 in steel wheel 12 both sides, cladding rubber wheel cover 13 on the rim face of foreign steamer 11, and hydraulic motor 14 installs on the inside cardboard of steel wheel 12 with bolted connection, and the hydraulic motor 14 other end and shaft 4 fixed mounting, and public-railway dual-purpose H type wheelset device 1 passes through the flange at hydraulic motor 14 tip and is connected with shaft 4, can be connected with equipment frame 2 through mounting base 3. When hydraulically driven, the hydraulic motor 14 rotates the steel wheel 12, the outer wheel 11 and the rubber wheel hub 13.
The above, only for the concrete implementation of this utility model, but the scope of protection of this utility model is not limited to this, and any person skilled in this technical field is in the technical scope of this utility model discloses, according to the technical scheme of this utility model and novel design add in equal replacement or change, all should be covered in the scope of protection of this utility model.
