Abstract
The utility model relates to a crawler tensioning device of an amphibious special vehicle, and belongs to the field of special vehicles. The crawler tensioning device of the amphibious special vehicle is characterized in that a torsional spring, a spline shaft, a tensioning wheel frame body, a regulating bolt, a tensioning wheel and a tensioning wheel shaft are sequentially connected to ultimately tension a crawler. The crawler tensioning device of the amphibious special vehicle has the benefits as follows: the crawler tensioning device facilitates regulation of a driver, reduces cost and improves the safety and the reliability of the vehicle.
Description
Technical field
The utility model belongs to the special vehicle field, a kind of track takeup of amphibious special vehicle.
Background technology
The construction machinery and equipment crawler belt is commonly used hydraulic tensioning with tightening device at present, and there is leakage of oil in this tensioning mode, adjusts the shortcomings such as inconvenient, that safe reliability is low when applying to amphibious special vehicle.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of mechanical type crawler tensioning of special vehicle special use is provided, and it is easy to adjust, saves cost, and safety, the reliability of vehicle under high-speed travel state is greatly improved.
The utility model for achieving the above object, by the following technical solutions: the track takeup of amphibious special vehicle, comprise torsion spring, castellated shaft, tension wheel support body, adjust bolt, tension wheel, tension wheel shaft, it is characterized in that: the tension wheel support body relies on bolt to be connected with castellated shaft, castellated shaft and torsion spring spline joint, adjust bolt and connect tension wheel shaft and tension wheel support body, tension wheel is bearing on the tension wheel shaft with bearing.
The beneficial effects of the utility model: this tightening device is convenient to the chaufeur adjustment, reduces the safe reliability of cost, raising vehicle.
Description of drawings
Accompanying drawing is schematic diagram of the present utility model.
1. torsion spring 2. castellated shafts 3. tension wheel support bodys 4. are adjusted bolt 5. tension wheels 6. tension wheel shafts
The specific embodiment
As shown in the figure, tension wheel support body 3 relies on bolt to be connected with castellated shaft 2, and castellated shaft 2 is used spline joint with torsion spring 1, adjusts bolt 4 and connects tension wheel shaft 6 and tension wheel support body 3, and tension wheel 5 usefulness bearings are bearing on the tension wheel shaft.
Principle of work
As shown in the figure, torsion spring 1 is connected by castellated shaft 2 with tension wheel support body 3.When tension wheel 5 ran into obstacle in the Vehicle Driving Cycle process, the tension wheel support body rotated around torsion spring, and the torsion spring torsional deflection produces and swings torsional angle, plays buffering and cushioning effect.Regulate to adjust bolt 4 length, tension wheel shaft 6 turned an angle, thereby and the jam nut position that changes tension wheel 5 reach the purpose of tensioned tracks.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment does.
Claims (1)
1. the track takeup of an amphibious special vehicle, comprise torsion spring, castellated shaft, tension wheel support body, adjust bolt, tension wheel, tension wheel shaft, it is characterized in that: the tension wheel support body relies on bolt to be connected with castellated shaft, castellated shaft and torsion spring spline joint, adjust bolt and connect tension wheel shaft and tension wheel support body, tension wheel is bearing on the tension wheel shaft with bearing.
