Abstract

The invention discloses a car running mode emission testing accelerator control device. The car running mode emission testing accelerator control device comprises an accelerator adjusting lead screw and an accelerator adjusting nut which are in screw-thread fit. The car running mode emission testing accelerator control device is characterized by further comprising a horizontally-arranged base plate and a base plate fixing device for fixing the base plate, the accelerator adjusting nut is arranged above one end of the base plate in an inclined fixing and supporting mode, a long-strip-shaped accelerator pressing plate is arranged below the accelerator adjusting nut, the lower end of the accelerator pressing plate is arranged on the upper surface of the base plate in a rotatable mode, the upper end of the accelerator pressing plate wholly extends out of the base plate in a forwards-inclined mode so as to form a force application end used for being in contact with an accelerator pedal, and the lower end of the accelerator adjusting lead screw is arranged in the mode of facing the upper surface of the accelerator pressing plate so that the accelerator pressing plate can be tightly pressed through the accelerator adjusting lead screw. By means of the car running mode emission testing accelerator control device, manpower can be replaced so as to achieve the accelerator pedaling motion, the accelerator control stability is guaranteed, the testing accuracy is improved, and the integrity of a tested vehicle can be guaranteed. The car running mode emission testing accelerator control device has the advantages of being simple in structure, convenient, rapid, stable and reliable to operate and the like.

Description

technical field [0001] The invention relates to the field of automobile emission test equipment, in particular to an accelerator control device for emission test of automobile working condition method. Background technique [0002] Before the automobile is produced and leaves the factory, it is necessary to carry out the emission test of the vehicle operating condition method to check whether the engine emission can meet the requirements when the vehicle is in different environments. During the emission test of the vehicle working condition method, the vehicle is located in the test environment chamber and is in an overhead state, and the test environment chamber provides different temperature environment simulations. Then it is necessary to depress the accelerator pedal of the vehicle to accelerate the wheels to a certain speed, then stabilize at a certain speed and maintain it for a certain period of time. [0003] In the prior art, the accelerator pedal is generally step...
