Abstract
The present invention discloses a caterpillar band drive device, belonging to an engineering machine, comprising a body, a motor speed reducer (1), a speed-reducing differential mechanism (3) for the back axle of a car, and a thrust wheel (10). The body is provided with driving wheels (7), guiding wheels (15), a trolley beam (9), and a caterpillar band (11). The motor speed reducer is connected with the speed-reducing differential mechanism for the back axle of a car through a drive shaft, and the driving wheels are arranged on the main shaft of the body. The present invention is characterized in that the output end of the speed-reducing differential mechanism for the back axle of a car is provided with a spline shaft with a small gear wheel (4), and the main shaft of each driving wheel is provided with a big gear wheel (5); the small gear wheel and the big gear wheels are mutually engaged; the front of the body and the back of the body are provided with two pairs of guiding wheels and two pairs of driving wheels. The present invention which uses the speed-reducing differential mechanism for the back axle of a car and uses the engagement among the small gear wheel and big gear wheels has the advantages of simple and reliable drive structure, low cost, small contact area pressure ratio, and positive using effect on the application of plenty of engineering machines.
Description
[technical field]
What the present invention relates to is a kind of caterpillar driving device that is used for construction machinery and equipment.
[background technology]
At present, the driving that is applied to the various crawlers body of construction machinery and equipment generally all is to adopt low-speed big torque motor or drive with the large speed ratio retarder of special use, a kind of prevailing caterpillar driving device, it is that drive wheel is directly installed on the retarder of large speed ratio, the caterpillar driving device of this structure, its structure more complicated, the cost height, and this caterpillar driving device both sides have only a crawler belt respectively, the crawler body grounding pressure is big, be trapped in wherein easily when causing crawler body on soft soil foundation, to walk, and when retarder is damaged, keep in repair cumbersome.
[summary of the invention]
In view of the problem that known technology exists, the object of the present invention is to provide a kind of simple in structurely, be suitable on weak soil, walking, and caterpillar driving device with low cost.
For achieving the above object, the present invention adopts following scheme to finish: a kind of caterpillar driving device, include body, motor speed reducer, automotive rear axle speed-reducing diff and caterpillar wheel, drive wheel is installed on the body, guide wheel, chassis beam and crawler belt, described motor speed reducer is connected with the automotive rear axle speed-reducing diff by transmission shaft, described drive wheel is installed on the main shaft of body, it is characterized in that the mouth of described automotive rear axle speed-reducing diff is equipped with the castellated shaft of band miniature gears, on the main shaft of drive wheel, big gear wheel is installed, described miniature gears and big gear wheel are meshing with each other, and the front and back of described body are equipped with two pairs of guide wheels and drive wheel.
Tightening device is equipped with at the middle part of described guide wheel.
The adapter shaft of described body caterpillar wheel is provided with bolster, and this bolster and described chassis beam constitute two T-shape structures.
The present invention adopts automotive rear axle speed-reducing diff in the known technology as accessory, deferent segment at the automotive rear axle speed-reducing diff is equipped with band miniature gears castellated shaft, this miniature gears and the big gear wheel engagement of installing on the drive wheel main shaft, its structure is very simple, and after adopting this device, moment of torsion is very big, can drive the crawler body walking effectively, because its simple structure, and these parts can purchase everywhere, have also just reduced cost of manufacture of the present invention; The front and back of body are equipped with two pairs of guide wheels and drive wheel, that is to say and take two crawler travels, increase crawler body, the grounding pressure of crawler body is reduced, be more suitable on soft soil foundation, walking ground-surface area of contact.
[description of drawings]
The present invention has following accompanying drawing:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the side portion structure scheme drawing of Fig. 1 of the present invention;
Fig. 3 shows structural representation for Fig. 2 of the present invention along cuing open of A-A.
[specific embodiment]
Accompanying drawing has been represented structure of the present invention and embodiment thereof, further describes each relevant details of embodiment below more in conjunction with the accompanying drawings.This caterpillar driving device, include body 16, motor speed reducer 1, automotive rear axle speed-reducing diff 3 and caterpillar wheel 10, drive wheel 7 is installed on the body 16, guide wheel 15, chassis beam 9 and crawler belt 11, described motor speed reducer 1 is connected with automotive rear axle speed-reducing diff 3 by transmission shaft 2, described drive wheel 7 is installed on the main shaft 6 of body 16, described automotive rear axle speed-reducing diff 3 the two ends mouth be equipped with the band miniature gears 4 castellated shaft (not marking among the figure), on the main shaft 6 of drive wheel 7, be installed with big gear wheel 5, form a device that is equivalent to drop-gear box, described miniature gears 4 is meshing with each other with big gear wheel 5, the front and back of described body 16 are equipped with two pairs of guide wheels 15 and drive wheel 7, in order to reduce the grounding pressure on crawler belt 11 chassis, the middle part of described guide wheel 15 is equipped with tightening device, this tightening device is a top fork, that is to say jack 14 is set on push rod 13, pitch with jack crawler tensioning by described top, add Upper gasket on the both sides of 15 of guide wheels then, make crawler belt 11 keep tensioning state, in order to prevent that push rod 13 breaks away from guide wheel 15, in the jack 14 of top fork, insert latch, push rod is remained on certain position; The adapter shaft of described body caterpillar wheel 10 is provided with bolster 17, and this bolster 17 constitutes two T-shape structures with described chassis beam 9, to keep the stability of chassis beam 9; Described motor speed reducer 1 promptly is installed on the crossbeam 12 of chassis beam 9.When the present invention works, the power of motor speed reducer 1 enters the automotive rear axle speed-reducing device by transmission shaft 2, be transferred to the castellated shaft of automotive rear axle differential gear two mouths by the screw bevel gear in the automotive rear axle speed-reducing device, miniature gears 4 on the castellated shaft drives two big gear wheels 5 on the main shaft 6, the other end of main shaft 6 is fixed with two link blocks 8, link block respectively on the power transmission drive wheel 7, and drives crawler belt 11 walkings by the pin on it and bolt (not shown).The present invention is simple in structure, and is with low cost, is particularly suitable for being applied on the piling equipment.
