This structure, will consider the installation position of stepper motor in design, and the angle between by-pass intake duct and air outlet channel is large as far as possible, and both joints need seamlessly transit, and have not allowed cusp.In this integral die-cast part, die casting will go out meet the idle speed bypass road of usage requirement, the difficulty that manufactures and designs of die casting mould is strengthened.Meanwhile, die castings adds man-hour, and bending by-pass place easily forms trachoma, pore and produce waste product.
Model utility content
The purpose of this utility model is the shortcoming overcoming prior art, provide a kind of to reducing costs, improve product performance, improve the integrated type of assembly stability and change split type vehicle air throttle.
The purpose of this utility model is achieved through the following technical solutions: a kind of integrated type changes split type vehicle air throttle, it comprises tb, throttle plate pin, throttle blade, swing frame assembly, torsion spring, position transducer, stepper motor, idling valve seat and idle adjusting screw, throttle plate pin is arranged on tb by bearing, one end extension of throttle plate pin is stretched out outside tb, torsion spring and swing frame assembly are installed successively stretching out on the throttle plate pin outside tb, position transducer and stepper motor are arranged on tb, throttle blade is arranged on throttle plate pin by Self-locking screw, tb is provided with water circulation channel on throttle blade position, tb is provided with idling valve seat and idle adjusting screw, tb and idling valve seat constitute idle speed bypass road jointly, idle speed bypass road comprises intake duct and air outlet channel, and intake duct and air outlet channel are rectangular-shaped, tb is also provided with tongue piece near idle speed bypass road place.
Described water circulation channel comprises an intake pipe and an outlet pipe.
Described idle adjusting screw is arranged on swing frame assembly place.
Described tongue piece is arranged on air outlet channel place.
The utility model has the following advantages:
1, throttle body assembly adopts split-type structural, decreases the design difficulty of mould; By-pass intake duct and air outlet channel are directly pumped into, and do not need machining, avoid the generation of pore, sand holes; The suction port of by-pass and formation right angle, air outlet, can effectively reduce, along stroke pressure loss, to avoid uttering long and high-pitched sounds; A tongue piece in air outlet channel outlet port, by-pass, can effectively reduce the carbon distribution of by-pass and stepper motor; Idling valve seat separates die casting with body, and what reduce mould manufactures and designs difficulty, provides product performance.
2, bearing adopts needle bearing, and cost is low, stable performance.
3, adopt plastics swing frames assembly, cost is low, good stability, for the initial assembling of producer and later maintenance provide great convenience.
4, flange surface is designed to a large sealing strip, can meet the plastic air intake manifold sealing means different with aluminum alloy air inlet manifold two kinds by throttle valve body simultaneously, expand market.
