Abstract
The invention discloses an auxiliary tool for chassis power testing of a four-wheel-drive vehicle. The auxiliary tool comprises a frame body, wherein two rectangular cavities are formed in the frame body; the two rectangular cavities are mutually parallel and are symmetric about the axis of the frame body; a plurality of mutually-parallel rollers are installed in the frame body, and the axis of each roller is mutually vertical to the axis of the frame body; a roller braking mechanism is also arranged on the frame body. When the chassis of the four-wheel-drive vehicle needs to be tested, firstly, the roller braking mechanism is used for braking the rollers so as to enable the rollers to be in a state of no rotation, the front wheels or the rear wheels of the four-wheel-drive vehicle roll onto the rollers, any two rollers support the wheels of the four-wheel-drive vehicle, then the braking mechanism is loosened, and the testing can be conducted. During testing, the wheels rotate under the driving of an engine and are used as driving wheels for providing power for the rollers, and rollers rotate, at the moment, the wheels are in a realest simulation motion state, and the power testing can be conducted on a single wheel.
Description
Technical field
The present invention relates to a kind of aid, specifically refer to the aid of a kind of 4-wheel driven car chassis power test.
Background technology
Vehicle testing technique is from auto repair derives from technology out, is accompanied by the development of automotive engineering by auto repair.In auto repair process in early days, mainly to find vehicle failure and do to repair targetedly by experienced maintenance personal, pass by " hoping (soon) " that people often say (for example: by observing automobile appearance or vehicle running state failure judgement), " hear (ear is listened) " (such as: by running sounding failure judgement such as engines), " ask (inquiry) (for example: by inquiry drive personnel's vehicle service condition or phenomenon failure judgement), (for example: by hand, touch and experience temperature " cut (hand is touched) ", vibration, the phenomenon failure judgement such as pressure) mode.Along with the progress of dynamo-electric observation and control technology progress, particularly computer technology of modern times, vehicle testing technique is develop rapidly also.People can rely on various advanced persons' instrument and equipment at present, and automobile is carried out to not dissection test, and safety, rapid, reliable.Safety and environmental protection detects and to refer to automobile is carried out to the detection that carry out regular and irregular safe operation and environmental protection aspect; Object is in not disintegration of automobile situation, to set up safety and public hazards monitoring system, guarantees that vehicle has satisfactory outward appearance appearance and good security performance, and the environmental of restricting vehicle moves it under safety, efficient and low pollution operating mode.Combination property detects and refers to the detection of automobile being carried out to regular and irregular combination property aspect; Object is in not disintegration of automobile situation, operational vehicle is determined to its ability to work and technology status, find out fault or hidden danger position and reason, maintenance vehicle is carried out to quality supervision, set up quality supervision system, guarantee that vehicle has good security, reliability, dynamic property, economy, exhaust gas purification and noise pollution, to create larger economic benefit and social benefit.
4-wheel driven car be exactly before and after the automobile of differential linkage four-wheel drive because engine power reaches four tires, so four-wheel all can be had an effect, so 4-wheel driven car cross-country ability is superior, also can handle a situation with ease in hillside, beach, mud ground, desert in the wild.Common two drive when wherein one driving wheel-slip, and other driving wheel also can run out of steam, and at this moment, just car can not travel, if car is four-wheel drive, two so other wheels still can be brought into play tractive force.Therefore 4-wheel driven car cross-country ability is superior, and also can handle a situation with ease in hillside, beach, mud ground, desert in the wild, and this indomitable hard style of sending has obtained liking of many car fans.The chassis power of 4-wheel driven car is measured by dynamometer machine at present, because four wheels of 4-wheel driven car are all connected with engine, all driving wheels, therefore, need to measure the powertrace of each wheel, while conventionally testing, be to adopt the wheel hanging of not testing, the mode of tested wheel for testing, so in test process, there is certain problem, in the time of unsettled, to utilize other the instrument that holds or lifting device to act on car body, easily car body is caused to damage, simultaneously, the accurate parameter of tester running status due to tilting of car body, easily distortion.
Summary of the invention
The object of the present invention is to provide the aid of a kind of 4-wheel driven car chassis power test, change the method for testing of current 4-wheel driven car chassis power test, reach the object of true measurement chassis power.
Object of the present invention is achieved through the following technical solutions:
The aid of a kind of 4-wheel driven car chassis power test, comprise framework, framework has two rectangular cavitys, two rectangular enclosures are parallel to each other and are symmetrical about the axis of framework, a plurality of cylinders that are parallel to each other are all installed in each framework, the axis of cylinder is mutually vertical with the axis of framework, is also provided with the arrestment mechanism of cylinder in framework.Framework adopts existing shaped steel to be welded, it is rectangular parallelepiped on the whole, surface is rectangle, shorter axis of symmetry both sides at rectangle are distributed with two rectangular enclosures, a plurality of cylinders are installed in cavity, cylinder distributes in the same horizontal line, the cylinder of the same side is parallel to each other, the cylinder of both sides is symmetric, arrestment mechanism is also installed in framework, arrestment mechanism can be all passable for common existing any mechanical braking structure, its effect is the rotation of index drum, make state or the on-position of cylinder in can freely rotating, when needs are tested 4-wheel driven car chassis, first utilize arrestment mechanism by drum braking, make its state in not rotating, the front-wheel of 4-wheel driven car or trailing wheel are rolled on cylinder, by any two cylinders, the wheel of 4-wheel driven car is carried out to supporting function, then arrestment mechanism is unclamped, just can test, during test, wheel rotates under the drive of engine, and provide power as driving wheel for cylinder, cylinder rotates, now in the most real skimulated motion state, can carry out power test to single wheel.
Described cylinder is cylindrical, in its outer setting, has the emery that one deck is wear-resisting.Further, as a further improvement on the present invention, adopt at the wear-resisting emery of cylinder arranged outside, form wearing layer, increase the friction factor between wheel and cylinder, prevented that wheel breaks away with respect to cylinder in rotation process, kept the stability of its test.
On the surface of described framework, be provided with the anti-skid structure that protrudes from framework.Further, as a further improvement on the present invention, front and back at 4-wheel driven car test process, conventionally need people to walk in framework, by the surface in framework, anti-skid structure is set, can guarantee that tester does not slip injured, concretely, can adopt the form of welding checkered plates on framework, the anti-skid structure that utilizes checkered plates surface to protrude, has the simple feature of processing.
The present invention compared with prior art, has following advantage and beneficial effect:
The aid of a kind of 4-wheel driven car of 1 the present invention chassis power test, when needs are tested 4-wheel driven car chassis, first utilize arrestment mechanism by drum braking, make its state in not rotating, the front-wheel of 4-wheel driven car or trailing wheel are rolled on cylinder, by any two cylinders, the wheel of 4-wheel driven car is carried out to supporting function, then arrestment mechanism is unclamped, just can test, during test, wheel rotates under the drive of engine, and provide power as driving wheel for cylinder, cylinder rotates, now in the most real skimulated motion state, can carry out power test to single wheel,
