Description
Technical field
It is used for Throttle Opening Control the present invention relates to a kind of accelerator control device tested for motor vehicle emission, more particularly to one kind
The bottom plate fixing device of device.
Background technology
, it is necessary to carry out vehicle working condition method emission testing before automobile production is dispatched from the factory, to detect that vehicle, in varying environment, starts
Can machine working displacement reach requirement.Automobile is located in experimental enviroment storehouse and in built on stilts shape during vehicle working condition method emission testing
State, experimental enviroment storehouse provides different temperature environment simulations.Then need to step on vehicle accelerator pedal that wheel is accelerated into one
It is stable constant and to maintain the regular hour in a certain speed after constant speed degree.
Throttle is trampled in general manually operation in the prior art, but it is artificial trample the throttle time it is longer when, can cause to trample
Less stable, force fluctuation is larger, produces error.Particularly experimental enviroment storehouse carries out especially serious during hot environment simulation.
And accurate data are needed in vehicle R＆D process data acquisition, fluctuation of service can cause gathered data inaccurate.Therefore completely
Manual operation tramples throttle and just seems extremely difficult, and fluctuation will occur in maintenance process in vehicle rotating speed to be come again.Sometimes for
Repetition test, takes a lot of work, laborious and test data distortion.
China's number of patent application 200920095038.6 once disclosed a kind of refueling accelerator pedal mechanical control device, by silk
Bar, fixing nut and adjusting knob composition, fixing nut are arranged on screw mandrel, and adjusting knob is arranged on the end of screw mandrel.Pass through
The rotation number of turns of adjusting knob and screw mandrel stroke are linear relationships, can accurately be controlled by changing the rotation number of turns of regulation
Accelerator open degree.
In the device of above-mentioned patent, the control to gas pedal can be realized by coordinating by feed screw nut, but the device is to set
It is placed on vehicle chassis dynamometer and uses, it is impossible to be directly used in vehicle interior and use, simultaneously because vehicle working condition method emission testing
Shi Buneng destroys vehicle self structure, therefore the device cannot be directly used to the behavior method discharging experiment of vehicle.
In order to solve the above problems, applicant devises a kind of vehicle behavior method emission testing accelerator control device, including
Throttle adjustment screw mandrel and throttle adjustment nut that mutual screw thread coordinates, it is characterized by, in addition to a horizontally disposed bottom plate
With the bottom plate fixing device for fixing bottom plate, the oblique fixed support of the throttle adjustment nut is arranged above bottom plate one end,
The throttle pressing plate of a strip is provided with below throttle adjustment nut, throttle pressing plate lower end is rotatably arranged in bottom plate upper table
Face, throttle pressing plate upper end is integrally extendable diagonally forward to be gone out bottom plate and to form force side for contacting gas pedal, and the throttle is adjusted
Rectify under section screw mandrel and throttle pressing plate upper surface is set and be can be used in compress throttle pressing plate.
So the device is in use, can replace artificial realization to trample throttle action, it is ensured that Throttle Opening Control stability, carry
High test accuracy.The throttle pressing plate for rotating connection which provided lower end and bottom plate exerts a force to gas pedal, being capable of preferably mould
(it is heelstrike fulcrum that people's pin tramples throttle to be also to the effect that anthropomorphic pin is trampled, and is rotated by tiptoe to going down and tramples gas pedal
Force), it is ensured that the reliability of experiment.
But how wherein, bottom plate fixing device be set, make it have it is simple in construction, complete bottom plate fix operation is very easy
Fast, good fixing effect, and will not damage the effect of vehicle self structure, the problem of as needing further to be considered.
The content of the invention
For above-mentioned the deficiencies in the prior art, the technical problems to be solved by the invention are：How a kind of structure letter is provided
It is single, complete bottom plate quick, good fixing effect of fixing that operation is very easy, and will not damage vehicle self structure be used for throttle control
The bottom plate fixing device of device processed.
In order to solve the above-mentioned technical problem, present invention employs following technical scheme：
A kind of bottom plate fixing device for accelerator control device, it is characterised in that the bottom plate fixing device includes one
Individual to be hinged the quadric chain constituted by four interlinking lever ends, a pair of diagonal formed of quadric chain are used for and automobile driver seat
The abutment end abutted with bridge, is provided with quadric chain and supports for controlling diagonal folding angle and then can adjust two
Connect and a clamping screw is additionally provided with the angle adjustment mechanism of end distance, quadric chain, clamping screw is integrally vertically set
