Description
Technical field
The present invention relates to throttle plate pin technical field, specially a kind of throttle plate pin with axial positioning structure.
Background technique
In throttle body, throttle plate pin is usually provided with axial direction positioning device, for controlling the phase of throttle plate pin installation
To position, to limit shaft axial movement value.Currently, the axial customization of throttle plate pin, mainly pacifies in one end of throttle plate pin
Gasket and retaining ring are filled, the other end installs torsional spring；Meanwhile slot is provided on throttle plate pin, positioning pin is provided in slot, this is fixed
Position pin is cylindrical type, and one end of which is fixed on ontology axis hole, the other end is protruded into slot；To pass through the cooperation of gasket and retaining ring,
And the cooperation of positioning pin and slot limits relative position and the axial float of throttle plate pin installation.
But in order to guarantee the strength and stability of resin gasket, the thickness of resin gasket is usually all thicker to be not less than
1mm, to cause in assembly to be higher to space requirement；Also, after being used for a long time, resin gasket can make its axis because of aging
It is weak to bearing capacity, cause it is easily-deformable after axially loaded, air throttle occur clamping stagnation or it is stuck situations such as.Although the surface of retaining ring applies
It is covered with antirust paint, but during throttle plate pin rotation, after split washer and resin gasket friction, easily leads to the anti-of its surface
Rust paint grinds off and gets rusty；To influence the normal work of throttle body.In addition, it is fixed to carry out throttle plate pin by positioning pin and slot
Position, not only assembly construction are more troublesome, and also can generate friction because of the axial transmission of throttle plate pin between positioning pin and slot,
Easily cause the abrasion of throttle plate pin and positioning pin, be also easy to cause air throttle occur clamping stagnation or it is stuck situations such as, therefore a kind of band
There is the throttle plate pin of axial positioning structure to come into being.
Summary of the invention
For realize it is above-mentioned prevent door-hinge axial float and occur clamping stagnation or it is stuck, improve stability, increase the service life purpose,
The invention provides the following technical scheme: a kind of throttle plate pin with axial positioning structure, including axis body, the inside of the axis body
It is fixedly connected with hollow channel, the two sides of hollow channel are connected with compressed spring, and compressed spring is far from hollow channel
One end is connected with positioning mechanism, and the internal activity of hollow channel is connected with rotary sleeve, and the positioning mechanism includes support frame,
The two sides of support frame are fixedly connected to exhaust pipe, and the internal activity of support frame is connected with position-limiting tube, the upper end activity of position-limiting tube
It is connected with idler wheel, the lower end of position-limiting tube is fixedly connected with latch.
The beneficial effects of the present invention are:
1. by the suitable position that axis body is mounted on to throttle body, when its work, air-flow can be flowed into hollow channel,
And through rotary sleeve change flow to, enable its flow into the airflow channel of hollow channel two sides, compressed spring under the blowing of air-flow into
Row is shunk, and pushes the position-limiting tube in positioning mechanism, and position-limiting tube generation is pushed, and connects the idler wheel of the upper end with throttle body
Touching, so that the axial force for absorbing air-flow is changed into axial shear force, and air-flow power is bigger, the contact force of idler wheel and door body is bigger,
To achieve the effect that prevent door-hinge axial float and clamping stagnation or stuck phenomenon occur.
2. driving idler wheel mobile by air-flow, when needing that intake is adjusted, the elastic force of compressed spring is adjusted,
And then change its contact area with latch, after the contact area of the two becomes smaller, enter in positioning mechanism from airflow channel
Air quantity will reduce, furthermore when enter axis body air quantity it is larger when, can be flowed through into the air-flow in positioning mechanism through grip block
And be discharged from exhaust pipe, and the diameter of exhaust pipe is greater than the diameter of grip block, therefore air-flow can generate pressure difference therebetween,
That is the air pressure of grip block is small, and the air pressure of exhaust pipe is big, so squeezing grip block, and then clamps it to position-limiting tube, can
It prevents pair of rollers door body from generating biggish extruding force, and is damaged to, improve stability to reach, increase service life
Effect.
Preferably, the surface activity of the compressed spring is connected with airflow channel, has between airflow channel and hollow channel
Some a certain distance in order that preventing axis body air pressure inside excessive, and are damaged to.
Preferably, the two sides of the axis body are fixedly connected to bearing, and bearing is to connect convenient for it with throttle body.
Preferably, the two sides of the position-limiting tube are connected with grip block, and grip block is expanding material, ability expansive force by
Effects of air pressure.
Preferably, the position-limiting tube is hollow design, and is in the same center line with compressed spring, design in this way be for
When preventing from axial force being changed into axial shear force, and bring it about offset.
Preferably, support frame as described above is cambered design, and the top of support frame is fixedly connected with fixture block.
Preferably, the position-limiting tube is elastic material, and has certain elastic contractile force, and elastic force is less than compressed spring
Elastic force.
Preferably, the quantity of the positioning mechanism is two, and symmetrically placed centered on hollow channel.
