Description
Technical field
The utility model relates to a kind of parts of hauling engine, particularly a kind of public iron dual-purpose tractor truck railway back axle.
Background technology
No matter be automobile or track train, some the time, can need tractor truck to spur, the tractor truck that has various railroad hauling cars and on-highway motor vehicle to use at present, but the tractor truck that on-highway motor vehicle uses can not travel in orbit, and railroad hauling car often can not travel at highway, particularly railroad hauling car is after finishing traction work, need return along track, take track like this, make the level of resources utilization of rail not high, a kind of public iron dual-purpose tractor truck can travel at highway, it also can travel in orbit simultaneously, and when public iron dual-purpose tractor truck travelled in orbit, rail wheel worked, when public iron dual-purpose tractor truck when highway travels, rail wheel is inoperative, answers hoisting depth, built on stilts.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and a kind of public iron dual-purpose tractor truck railway back axle is provided.It can make the back rail wheel of public iron dual-purpose tractor truck promote or reduction.
The technical solution of the utility model is: a kind of public iron dual-purpose tractor truck railway back axle, it comprises driving system and elevator system.
Described driving system comprises: rail wheel, rail wheel rear axle, dust boot, nut, bearing, dust ring, two rail wheels are installed in two ends of rail wheel rear axle, the outside, center of rail wheel is equipped with nut, the nut outside is equipped with dust boot, the center of rail wheel is equipped with bearing, and the center inside of rail wheel is equipped with dust ring.
Described elevator system comprises: oil cylinder axle, back fork, copper sheathing, oil cylinder, back fork set pin, oil cylinder set pin, the oil cylinder axle is positioned at the middle and lower part of back fork, there is back fork set pin the upper end of back fork, there is copper sheathing the upper end of back fork set pin, the lower end of oil cylinder is connected on the fork of back by the oil cylinder axle, there is the oil cylinder set pin upper end of oil cylinder, and the lower end of back fork is fixed on the rail wheel rear axle.
The utility model compared with prior art has following characteristics: by the activity of oil cylinder, rail wheel is promoted or the reduction height.
Below in conjunction with the drawings and specific embodiments detailed construction of the present utility model is further described.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is the left view of accompanying drawing 1.
The specific embodiment
As shown in drawings: a kind of public iron dual-purpose tractor truck railway back axle, it comprises driving system and elevator system.
Described driving system comprises: rail wheel 4, rail wheel rear axle 5, dust boot 6, nut 7, bearing 8, dust ring 9, two rail wheels 4 are installed in two ends of rail wheel rear axle 5, the outside, center of rail wheel 4 is equipped with nut 7, nut 7 outsides are equipped with dust boot 6, the center of rail wheel 4 is equipped with bearing 8, and the center inside of rail wheel 4 is equipped with dust ring 9.
Described elevator system comprises: oil cylinder axle 1, back fork 2, copper sheathing 3, oil cylinder 10, back fork set pin 11, oil cylinder set pin 12, oil cylinder axle 1 is positioned at the middle and lower part of back fork 2, there is back fork set pin 11 upper end of back fork 2, there is copper sheathing 3 upper end of back fork set pin 11, the lower end of oil cylinder 10 is connected on the fork 2 of back by oil cylinder axle 1, there is oil cylinder set pin 12 upper end of oil cylinder 10, and the lower end of back fork 2 is fixed on the rail wheel rear axle 5.
Principle of work of the present utility model and using method are: when oil cylinder 10 shrinks, can drive rail wheel 4 moves to the upper right side, thereby raise the position of rail wheel 4, make rail wheel 4 deorbits, when oil cylinder 10 elongations, the below is mobile left can to make rail wheel 4, thereby reduce the position of rail wheel 4, rail wheel 4 is coincide in orbit, by the activity of oil cylinder 10, rail wheel 4 is promoted or the reduction height.
