Abstract
The invention is a detecting method and device of tail gas charge for an all-time four-wheel driven vehicle, including the steps: supporting rear drive wheels on double rollers by the hoister of a chassis work tester; supporting front drive wheels on a bracket by an auxiliary hoister. The device includes chassis work tester, auxiliary hoister and front wheel bracket; the rear drive wheels are supported by double rollers on the chassis work tester; the front drive wheels are supported by the front wheel brackets; as the vehicle starts up, the rear drive wheels drive the rollers on the chassis work tester to rotate and the front drive wheels races on the bracket. As compared with existing techniques, it implements simple working conditions detection for an all-time four-wheel driven vehicle and largely improves reality and comparability of discharge detection for this kind of vehicle.
Description
Technical field
The present invention relates to maintenance, the checkout equipment of vehicle, the ground that relates in particular to support vehicle connects the car device, particularly relates to the ground that cooperates Vehicular exhaust to detect usefulness and connects car method and device.
Background technology
The tail gas of modern motor vehicle emission is a principal element of urban atmospheric pollution, and vehicle exhaust detects the important means that also just becomes the control urban atmospheric pollution, generally all will carry out compulsory maintenance and maintenance to the vehicle that exhaust emission exceeds standard with up to standard.Existing tail gas pick-up unit can detect the vehicle of front-wheel drive or rear wheel drive, vehicle to four-wheel drive, must pluck the joint element between front-wheel and trailing wheel, make it be transformed into rear wheel drive or front wheel drive car just can detect, can only use idling or double idle method to detect the automobile of full-time four-wheel drive.So-called idling is not stepped on the gas with a lower speed rotation after being meant engine ignition, and a kind of duty of other drive disk assembly of not transmission automobile, the difference of double idle and the idling oiling that is to step on the gas, but still drive transmission part not, these two kinds of methods all can not truly reflect the pollution level to atmosphere.Prior art can't (be called for short: full-time four-wheel drive vehicle) carry out the detection of simple and easy operating condition method, simple and easy operating condition method refers to quicken the simulated condition method or the short operating condition method of transient state detects to the vehicle of rear bridge driven before whenever being.
Summary of the invention
The technical problem to be solved in the present invention is to avoid above-mentioned the deficiencies in the prior art part, and proposes a kind of detection method and device that can quicken simulated condition method or the short operating condition method emission detections of transient state to full-time four-wheel drive vehicle.
The technical scheme that the present invention solves the problems of the technologies described above employing is, proposes a kind of full-time four-wheel drive vehicle emission detections method, and comprise step: the lifting jack with chassis dynamometer props up rear drive sprocket on twin-roll; With auxiliary lifting device front driving wheel is propped up on support; When vehicle take-offs, the cylinder that described rear drive sprocket drives on the chassis dynamometer rotates, and front driving wheel dallies on support.
The technical scheme that the present invention solves the problems of the technologies described above employing also comprises, proposes a kind of full-time four-wheel drive vehicle emission detections device, comprises chassis dynamometer, auxiliary lifting device and front-wheel support; The rear drive sprocket of vehicle is supported by the twin-roll on the described chassis dynamometer; The front driving wheel of vehicle is supported by described front-wheel support; When vehicle take-offs, the cylinder that its rear drive sprocket drives on the chassis dynamometer rotates, and its front driving wheel dallies on support.
Compare with prior art, adopt the inventive method and device, changed and to have used idling or double idle method to detect the situation of full-time four-wheel drive vehicle exhaust emissions originally, thereby the simple and easy operating condition method that has realized full-time four-wheel drive vehicle detects, and makes this car type automobile produce very much progress aspect the authenticity of discharging detection, the comparability.

Fig. 3 is the structural representation of another embodiment of the full-time four-wheel drive vehicle emission detections of the present invention device.
Embodiment
Below in conjunction with the embodiment shown in the accompanying drawing invention is described in further detail.
Full-time four-wheel drive vehicle emission detections method of the present invention as described in Figure 3 and device, described method comprises step: with the lifting jack of chassis dynamometer with 12 of rear drive sprockets on twin-roll 22; With auxiliary lifting device 30 with 11 of front driving wheels on support 40.And described device comprises chassis dynamometer, auxiliary lifting device 30 and front-wheel support 40; The rear drive sprocket 12 of vehicle 10 is supported by the twin-roll on the described chassis dynamometer 22; The front driving wheel 11 of vehicle 10 is supported by described front-wheel support 40; When vehicle 10 started, the twin-roll 22 that its rear drive sprocket 12 drives on the chassis dynamometer rotated, and its front driving wheel 11 dallies on support 40.
Described testing process comprises: detected automobile 10 is opened to chassis dynamometer, its rear drive sprocket 12 is placed on the lifting jack of 22 on two cylinders, this moment, its front driving wheel 11 was sitting on the front-wheel lifting jack 30, the lifting jack of chassis dynamometer falls subsequently, and rear drive sprocket just falls and puts on two cylinders 22.Lift on the front-wheel lifting jack 30 at this moment, make front driving wheel 11 break away from ground 50, then support 40 is filled under the fixed mount of propons, 30 times backwardnesss of front-wheel lifting jack, front driving wheel 11 just is set on the support 40.When automobile 10 starts, its rear drive sprocket 12 drives that twin-roll 22 rotates on chassis dynamometers, and front driving wheel 11 is placed in idle running on the support 40.At this moment, this automobile can carry out normal stable state or the short operating condition method emission detections of transient state.
Existing as shown in Figure 1 common detection scheme for the vehicle of four-wheel drive, is worked as start, and vehicle will leave from the measurement stand, thereby this stand can not be used for the emission detections of full-time four-wheel drive vehicle.
As shown in Figure 2, can be with one with the support 40 shown in cylinder 21 alternate figures 3 of front driving wheel 11 rotations, but there are some differences in two kinds of technical schemes, promptly adopt Fig. 2 scheme, existing common detection scheme shown in Figure 1 relatively, will drive a servo-actuated cylinder 21 rotation, thereby automobile 10 will consume a part of wheel power more more, and cause the automobile harmful gas discharge value that records bigger than normal; And employing Fig. 3 scheme, compare with existing common detection scheme shown in Figure 1, because this moment, 11 of front driving wheels were done uncharge idle running, need not consume wheel power, thereby its testing result and conventional sense, be that existing standard is just the same, so just changed the situation that the emission detections of present full-time four-wheel drive vehicle can only use idling or double idle to detect, can realize the exhaust emissions level of full-time four-wheel drive vehicle and the emission level of common vehicle are carried out fair contrast on a kind of detection method.
