Abstract
The utility model relates to engineering machinery tyre type excavators, particularly to a tyre type forward-backward steering excavator. The tyre type forward-backward steering excavator comprises tyres, a front axle, a rear axle, a frame and a transmission system. The tyres are fixed on the frame after being connected with the front axle and the rear axle, the transmission system is composed of transmission case and a transmission shaft, and steering cylinders are fixed onto the front axle and the rear axle and connected with a steering gearbox through hydraulic pipes. The tyre type forward-backward steering excavator has the advantages of reducing sideslipping during steering, reducing the steering radius to a large extent, improving the steering stability during high-speed movement, achieving cross movement to facilitate parking, avoiding potential risks during application and filling gaps in the tyre excavator industry.
Description
Technical field
The utility model relates to a kind of off-the-road tyre formula excavating machine, particularly before and after a kind of rubber-tyred, turns to excavating machine.
Background technology
At present construction machinery industry wheeled excavator is all the pattern that adopts front-wheel steering, and its turn radius is large, and during turning, trailing wheel produces corresponding angle of slide and easily causes vehicle rotation or break away, and in use has very big inconvenience and potential safety hazard.
Utility model content
The utility model, in order to make up the defect of prior art, provides rubber-tyred front and back a kind of simple in structure, easy to use to turn to excavating machine.
The utility model is achieved by the following technical solution:
Before and after a kind of rubber-tyred, turn to excavating machine, comprise tire, propons, back axle, vehicle frame and driving system, described tire is fixed on vehicle frame after being connected with back axle with propons, described driving system is comprised of transmission gearbox and transmission shaft, and direction cylinder is separately fixed at propons and is connected with steering wheel on back axle and by hydraulic tubing.
Further, on the hydraulic tubing that described back axle is connected with steering wheel, change-over valve is installed.
Further, after described transmission gearbox is fixed on vehicle frame, by transmission shaft, be connected with back axle with propons respectively.
The beneficial effects of the utility model are: the sideslip while having reduced to turn, reduced to a great extent turn radius, when walking at a high speed, increased stationarity when car is turned, can realize horizontal walking is convenient to park, potential safety hazard has been avoided in the use of this car, and be convenient to the use of small space, filled up and taken turns the blank of digging industry.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is that the utility model four-wheel right-hand turning is to schematic diagram;
Accompanying drawing 3 is that the utility model front-wheel is to off hind wheel left-handed turning to schematic diagram;
Accompanying drawing 4 is the utility model schematic diagram of laterally walking.
In figure, 1 tire, 2 propons, 3 vehicle frames, 4 transmission shafts, 5 transmission gearboxs, 6 change-over valves, 7 direction cylinders, 8 back axles, 9 hydraulic tubings.
The specific embodiment
Accompanying drawing 1-4 is a kind of specific embodiment of the present utility model.Before and after a kind of rubber-tyred of this utility model, turn to excavating machine, comprise tire 1, propons 2, back axle 8, vehicle frame 3 and driving system, described tire 1 is fixed on vehicle frame 3 after being connected with back axle 8 with propons 2, described driving system is comprised of transmission gearbox 5 and transmission shaft 4, direction cylinder 7 is separately fixed at propons 2 and is connected with steering wheel on back axle 8 and by hydraulic tubing 9, on the hydraulic tubing 9 that described back axle 8 is connected with steering wheel, change-over valve 6 is installed, after described transmission gearbox 5 is fixed on vehicle frame 3, by transmission shaft 4, is connected with back axle 8 with propons 2 respectively.
Before and after a kind of rubber-tyred of this utility model, turn to excavating machine, during use, Fig. 2 is for beating direction to the right, the deflection to the right simultaneously of front-wheel trailing wheel can not produce rotational force because turning in traveling process, make car smooth running, this kind of state is mainly to use when walking at a high speed, Fig. 3 switches oil circuit by change-over valve 6, trailing wheel deflection left when front-wheel is beaten direction to the right, both counter motions, now turning center is positioned at front and back wheel perpendicular line intersection point, Turning radius is less than front-wheel steering, this state is mainly applicable to small space and turns to, wherein Fig. 3 also has other critical function exactly when platform is turned back to rear side, there is transformation in the car load gear of walking under this state, reverse gear originally becomes advances, forward gear has become reverse gear, realize the function that headstock becomes the tailstock, when Fig. 4 is direction cylinder 7 arrival stroke, tire 1 is in extreme position, now car can laterally be walked or be realized original place and spin.
The utility model is not limited to above-mentioned embodiment, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, within all falling into protection domain of the present utility model.
The technology that the utility model is not described in detail, shape, structure are partly known technology.
