Abstract
The invention provides a friction entire-driving multi-wheel tractor used for a road-surface accelerating and loading test device, belonging to the test equipment field. The structure comprises a draw bar, a spring, a lower rack, front wheels, middle wheels, rear wheels and an upper rack component, wherein the upper rack component is composed of an upper rack, a hydraulic motor, a driving wheel and a driven wheel; and the driving wheel is driven by the hydraulic motor to rotate. The friction entire-driving multi-wheel tractor is characterized in that when in a short-distance moving, the road-surface accelerating and loading test device falls on the upper rack of the tractor, the driving wheel arranged on the upper rack component is used for driving the front wheels and the middle wheels by friction, at the same time, the middle wheels are used for driving the driven wheel to drive the rear wheels to walk, thereby improving the efficiency of the road-surface accelerating and loading test. The tractor also has the characteristic that when in the free state, the upper rack component is bounced by the spring, the driving wheel and the driven wheel are not contacted with all wheels, and the wheels are in the automatic state to draw the draw bar, therefore, the tractor can be dragged.
Description
(1) technical field
The present invention relates to a kind of testing equipment, specifically a kind of friction entire-driving multi-wheel tractor that is used for road-surface accelerating and loading test device.
(2) background technology
It mainly is to lean on trailer traction that the short distance of existing road-surface accelerating and loading test equipment is moved, complicated operating process, and efficient is lower.
(3) summary of the invention
Technical assignment of the present invention is the deficiency to prior art; A kind of friction entire-driving multi-wheel tractor that is used for road-surface accelerating and loading test device is provided; Can realize better that the short distance of road-surface accelerating and loading test equipment moves, have efficient, energy-conservation, characteristics easily.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of friction entire-driving multi-wheel tractor that is used for road-surface accelerating and loading test device, its structure comprises towbar, spring, lower bearing bracket, front vehicle wheel, middle wheel, rear wheel and upper spider assembly; The upper spider assembly is made up of upper spider and oil motor, driving wheel, engaged wheel, and driving wheel is by the oil motor driven rotary, when the road-surface accelerating and loading test device short distance is moved; Road-surface accelerating and loading test device is dropped on the upper spider assembly, and the upper spider assembly falls on the lower bearing bracket, simultaneously compression spring; The driving wheel of upper spider assembly leans on friction-driven front vehicle wheel and middle wheel; Wheel drives engaged wheel by friction simultaneously, and engaged wheel leans on the friction-driven rear wheel again, during the tractor free state; The upper spider assembly is upspring by spring; Driving wheel, engaged wheel and front vehicle wheel, middle wheel, rear wheel all do not contact, and wheel all is in auto state, and hauling the towbar tractor can be moved in tow.
A kind of friction entire-driving multi-wheel tractor that is used for road-surface accelerating and loading test device of the present invention compared with prior art, the beneficial effect that is produced is:
1) the present invention adopts driving wheel to lean on the whole wheels of friction-driven, realizes that the short distance of road-surface accelerating and loading test device is moved, and has improved test efficiency, has reduced energy resource consumption.
2) during the tractor free state, haul towbar, tractor can be moved in tow, and is simple to operate, practices thrift cost.
(4) description of drawings
The structural representation of Fig. 1 traction state of the present invention.
The structural representation of Fig. 2 free state of the present invention.
Among the figure, 1, towbar, 2, driving wheel, 3, oil motor, 4, upper spider, 5, spring, 6, engaged wheel, 7, lower bearing bracket, 8, rear wheel, 9, middle wheel, 10, front vehicle wheel.
(5) embodiment
Explanation at length below in conjunction with Fig. 1 a kind of friction entire-driving multi-wheel tractor that is used for road-surface accelerating and loading test device of the present invention being done.
As shown in Figure 1; A kind of friction entire-driving multi-wheel tractor that is used for road-surface accelerating and loading test device of the present invention; Its structure comprises towbar 1; Spring 5, lower bearing bracket 7, rear wheel 8, middle wheel 9, front vehicle wheel 10 and upper spider assembly, and the upper spider assembly is made up of upper spider 4 and oil motor 3, driving wheel 2, engaged wheel 6, driving wheel 2 is by oil motor 3 driven rotary.
The above-mentioned friction entire-driving multi-wheel tractor that is used for road-surface accelerating and loading test device; When the road-surface accelerating and loading test device short distance is moved; Road-surface accelerating and loading test device is dropped on the upper spider 4 of tractor, upper spider 4 drops down onto on the lower bearing bracket 7, simultaneously compression spring 5; Be contained in assembly on the upper spider driving wheel 2, lean on friction-driven front vehicle wheel and middle wheel, walk through middle wheel drive engaged wheel 6 and then drive rear wheels simultaneously; Thereby drive whole wheels, move, improve the efficient of test with the short distance that realizes road-surface accelerating and loading test device.
As shown in Figure 2, when tractor was in free state, the upper spider assembly was upspring by spring 5, and driving wheel 2, engaged wheel 6 and whole wheels do not contact, and wheel all is in auto state, hauls towbar 1, and tractor can be moved in tow.
A kind of its processing and fabricating of friction entire-driving multi-wheel tractor that is used for road-surface accelerating and loading test device of the present invention is simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.
