The mechanical type air throttle body of automobile internal engine aspirating system mainly be housed in the throttle plate pin in the tb by warp beam and be installed on the throttle plate pin, the throttle blade that is arranged in the body air-flow main passage consists of.Throttle blade links to each other with gas pedal in the operator cabin by swing frame, wire rope and lever, the driver is by the pin accelerator pedal, draw turn swing frame, swing frame draws the trochanter air valve shaft to control the throttle blade aperture, thereby the area of gas-entered passageway in the change closure, regulate the air inflow of motor, reach under each operating mode of motor the requirement to air mass flow.When ambient temperature was low, the phenomenon of freezing appearred in the main passage of throttle body and by-pass, caused throttle blade to open difficulty, can't regulate air input of engine by air; The single torsion spring of installing on the throttle plate pin of traditional motor, the driver is when trampling the aperture of gas pedal adjusting joint bulla, and the moment of torsion of single torsion spring can not satisfy the throttle blade aperture can free adjustment, increases the difficulty that air input of engine by air is regulated.
The model utility content
The purpose of this utility model is to overcome the shortcoming of prior art, the improved mechanical type air throttle body that provide a kind of compactness rational in infrastructure, cost is low and engine performance stable, the throttle body functional reliability is high.
The purpose of this utility model is achieved through the following technical solutions: a kind of improved automobile-used mechanical type air throttle body, it comprises body, throttle plate pin, throttle blade and swing frame assembly, the two ends of throttle plate pin are installed on body interior by bearing, throttle blade is installed in the middle part of throttle plate pin, be positioned on the throttle plate pin of throttle blade one side axle sleeve and swing frame assembly also are installed successively, torsion spring A is contained on the inner ring of axle sleeve, and torsion spring B is contained on the outer ring of axle sleeve; One side of body is installed with stepper motor and position transducer, and position transducer links to each other with throttle plate pin, and the opposite side of body also is equipped with intake pipe, outlet pipe and support.
Offer annular groove on the described throttle plate pin, be provided with collar in the annular groove, the width of annular groove is slightly larger than the thickness of collar.
Described swing frame assembly is comprised of swing frame and rope support, and the swing frame assembly is fixedly mounted on the throttle plate pin by nut, also is fixed with limiting board between swing frame assembly and the nut.
Described body one side also is provided with adsorption tube.
Described bearing is grease-added needle bearing.
The utlity model has following advantage:
1, pass through architecture advances on the body, increased the support mounting point, reduced body design difficulty and cost of material, by the machining mode machining support tapped hole is installed, the tapped hole position dimension guarantees good, has improved the conformity that support is installed.Support Design is exquisite, and guaranteed performance when satisfying user's usage requirement greatly reduces design difficulty and the materials of support, has saved cost.
2, intake pipe, body interior passage and outlet pipe form water circulation channel, utilize hot water heating, body main passage and by-pass freeze and the throttle blade unlatching difficulty of appearance and the problem that stepper motor can't be worked when preventing low temperature, have improved the functional reliability of throttle body.
3, at throttle plate pin collar is set, collar is pressed in the bearing hole by bearing, can effectively control vertically play of throttle plate pin, thereby avoid because of the bad problem of throttle blade clamping stagnation return, the position of adjusting collar by controlling organization of axial clearance remains that the throttle body return is good.
4, utilize the assembling of inside and outside torsion spring to solve the product torsion problem, improved the travelling comfort of driver when trampling gas pedal.
5, bearing adopts grease-added needle bearing, and stable performance, good can solve the problem of closure clamping stagnation effectively.
6, swing frame assembly has the low and good stability of cost, for the initial assembling of producer and later maintenance provide great convenience.
