Description

A kind of modified model mechanical type vehicle air throttle

Technical field

The utility model relates to the Intaker controller of automobile internal motor, particularly a kind of modified model mechanical type vehicle air throttle.

Background technique

At present, as the throttle body assembly of the Intaker controller of automobile internal motor, its tb is that an integral aluminum alloy belongs to die castings, is provided with air inlet main passage and idling by-pass in it.Its effect is to adjust the air inlet supply, to adapt to engine start, the performance need under the different operating modes such as idling, acceleration, power character, Economy and the emission performance of assurance motor.On the flange plate of this integral die-cast part structure lightening hole is arranged all, to reduce pore, guarantee tissue density, for the ease of mold design, the lightening hole opening of general design is all on flange surface, the sealing means that has limited to product, secondly, radius structure such as the shape of swing frame rope groove generally is designed to, made things convenient for the calculating of gas pedal stroke like this, but in the process of car steering, the driver wishes more to quicken mild when keeping out, height raised speed comparatively fast at that time, waited the rope groove structure of radius obviously can not satisfy this requirement.

The model utility content

The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of modified model mechanical type vehicle air throttle is proposed, so that body is satisfying the manufacture difficulty alleviate this body weight, to reduce die castings when being convenient to flangeseal, the requirement faster of raising speed when quickening mild, high rotating speed when simultaneously, satisfying the running of motor.

The purpose of this utility model is achieved through the following technical solutions: a kind of modified model mechanical type vehicle air throttle, comprise tb, be installed in throttle plate pin in the tb, be installed in throttle blade, torsion spring, limiting board, swing frame assembly and idle adjusting screw on the throttle plate pin, be installed in sensor, stepper motor on the tb, described tb is provided with the flange plate of not being with lightening hole and independently heats water circulation channel, lightening hole is not set on the flange plate, and the heating water circulation channel is communicated with intake pipe and outlet pipe;

The rope groove of swing frame assembly is for becoming radius structure, and this change radius structure is a starting point with the stay cord pin hole of swing frame assembly, and is big toward radius change counterclockwise.

Described idle adjusting screw is a tapping screw.

Described change radius structure is made up of at least two sections circular arcs.

The bottom surface of described flange plate is along the wide 6～7mm in air outlet, flange surface main passage, the complete plane of thick 5～6mm.

Compared with prior art, the beneficial effects of the utility model show:

1, manufacture cost reduces

Because the flange plate attachment face is a complete plane, there has not been to be provided with the position of lightening hole, so just increased the probability of flange surface generation pore trachoma, but on this product, change lightening hole into the profile loss of weight, should change thin walled structures into by thick and heavy flange plate, promptly reduced raw-material use amount, reduce the probability of flange plate generation pore trachoma again, reduced the waster rate, reduced manufacture cost.

2, improved end product quality

Stay cord dish on the swing frame assembly is designed to become radius structure, promptly form by at least two sections section circular arcs, smooth connection between two sections circular arcs, there is not flex point, the one section radius of arc in front is bigger than normal, next one section radius of arc is less than normal, under the same situation of stroke, the circular arc rotation angle that radius is big is littler, thereby throttle body control air inflow is less, it is big that the little circular arc of breeding radius rotates control air throttle air inflow etc., thus this change radius stay cord dish structure can satisfy quicken when motor supports rotating speed mild, the requirement faster of raising speed during high rotating speed.

3, flange surface is designed to a big plane, can make throttle body satisfy two kinds of different sealing means of plastic air intake manifold and aluminum alloy air inlet manifold simultaneously, has enlarged market.

4, water circulation channel is independently heated in design on the body, the phenomenon of freezing around the throttle blade in the time of can effectively preventing the winter cold start-up.

5, idle adjusting screw is selected tapping screw for use, and tapping screw the time is satisfying in assembling and is easier to staff's operation under the identical usage requirement situation, has accelerated working efficiency, simultaneously, and the inaccuracy of the location when adopting tapping screw can reduce personnel's turn.
