Abstract

The utility model relates to a windscreen wipe dedicated for a heavy truck and a large bus. For the windscreen wiper dedicated for the heavy truck and the large bus, two wiper blades are respectively and independently driven by two motors; and the windscreen wiper comprises two reducing gears and a crank mechanism, wherein the two reducing gears are respectively driven by the two motors. In the utility model, the two motors with small power are used for driving a crank of the windscreen wipe through the reducing gears so as to drive the two wiper blades, a long four-bar mechanism is omitted, and the installation space is saved, meanwhile, the defects that the windscreen wiper works unreliably and unstably, and easily causes the locking phenomenon in the prior art can be overcome, so that the reliability and stability of the windscreen wiper are greatly improved.

Description

The special-purpose wiper of heavy duty truck and motor omnibus

Technical field

The utility model belongs to automobile technical field, relates to a kind of wiper, particularly is exclusively used in the wiper of heavy duty truck and motor omnibus.

Background technology

Wiper is one of safety member important on the automobile, and it can effectively remove sleet and dirt on the shield glass, gives one of chaufeur driving vision clearly, guarantees traffic safety.

At present; The wiper of heavy duty truck and motor omnibus by motor, retarder, four-bar linkage, scrape the water arm and several parts of swept area of wiper blade are formed; This wiper is driven two and is scraped water arm and swept area of wiper blade by a motor-driven four-bar linkage, and these two swept area of wiper blades are interlock.But because the operator's compartment of heavy duty truck and motor omnibus is comparatively roomy, and front windshield cambered surface curvature is long, and wiper all is installed in the two ends of operator's compartment; In a motor-driven wiper; The volume of four-bar linkage can become greatly, and designs very longly, and the installation of wiper can take very large space of operator's compartment so on the one hand; Can tie up a lot of bridge instrumentations space, be unfavorable for the integral layout of operator's compartment; The more important thing is that long four-bar linkage can cause wiper work unreliable, unstable, is easy to occur deadlock phenomenon.

Given this, be necessary to the wiper of heavy duty truck and motor omnibus further perfect.

Summary of the invention

The utility model is installed and to be occupied big and unreliable, the instability of working of cab space and be prone to locked problem in order to solve above-mentioned existing heavy duty truck and motor omnibus wiper; And a kind of double-motor stand alone type heavy duty truck and the special-purpose wiper of motor omnibus are proposed, to reduce installing space and to improve its reliability and stability.

The technical scheme of the utility model is following:

The special-purpose wiper of above-mentioned heavy duty truck and motor omnibus comprises motor and two windscreen wiper sheets, and said motor is two, respectively said two the windscreen wiper sheets of individual drive; Said wiper further comprises by separately-driven two speed reduction gearings of these two motors and crank mechanism; Said crank mechanism is made up of crank rocking arm, U type chute rocking arm and windscreen wiper rocking arm, and the clutch end of an end and said speed reduction gearing is hinged, and the other end connects said windscreen wiper sheet; Said crank rocking arm one end is captiveed joint with the power take-off shaft of said speed reduction gearing, and the other end is connected with said U type chute rocking arm; The other end and the said windscreen wiper swing arm of said U type chute rocking arm are hinged, and said U type chute rocking arm has chute, the other end sliding connection of said chute and said crank rocking arm.

The special-purpose wiper of described heavy duty truck and motor omnibus, wherein: said wiper also comprises bracing frame, support frame as described above is connected with said crank mechanism through the jointed shaft of said U type chute rocking arm and windscreen wiper swing arm.

The special-purpose wiper of described heavy duty truck and motor omnibus, wherein: said speed reduction gearing adopts turbine and worm decelerator.

The special-purpose wiper of described heavy duty truck and motor omnibus, wherein: said two motors adopt Single-chip Controlling.

Beneficial effect:

The utility model is owing to adopt two lower-powered motor via reducer structures to drive the Windshield Wiper crank; Drive two windscreen wiper sheets; The structure letter is gathered, and has removed long four-bar linkage, has reduced installing space; Overcome the deficiency that the special-purpose wiper work of medium and heavy truck of prior art and motor omnibus is unreliable, unstable, be easy to occur deadlock phenomenon simultaneously, thereby improved the reliability and stability of wiper greatly.

Description of drawings

Fig. 1 is the heavy duty truck of the utility model and the structural representation of the special-purpose wiper of motor omnibus.

Fig. 2 is the heavy duty truck and the special-purpose rain shaving electrical machine control principle of the motor omnibus figure of the utility model.

The specific embodiment

As shown in Figure 1; The special-purpose wiper of heavy duty truck of the utility model and motor omnibus is made up of the relatively independent driver train of two covers; Comprise that two motors 1 reach by these two motors, 1 separately-driven two speed reduction gearings 2, crank mechanism 3, bracing frame 4 and windscreen wiper sheet 5, promptly a motor 1 drives a windscreen wiper sheet 5.

Be that example specifies the utility model with a cover driver train below:

Speed reduction gearing 2 is a turbine and worm decelerator in the present embodiment, clutch end connecting crank mechanism 3;

Crank mechanism 3 is made up of crank rocking arm 31, U type chute rocking arm 32 and windscreen wiper rocking arm 33; Wherein crank rocking arm 31 1 ends are captiveed joint with the power take-off shaft of speed reduction gearing 2, and the other end is connected with U type chute rocking arm 32; The other end and the windscreen wiper swing arm 33 of U type chute rocking arm 32 are hinged, and this U type chute rocking arm 32 has chute 320, the other end sliding connection of this chute 320 and crank rocking arm 31.

Bracing frame 4 is connected with crank mechanism 3 through the jointed shaft of U type chute rocking arm 32 and windscreen wiper swing arm 33, in order to support crank mechanism 3, and plays fixation.

Windscreen wiper sheet 5 is installed in the front end of windscreen wiper swing arm 33, swings with the swing of windscreen wiper swing arm 33.

Job description:

Motor 1 is after speed reduction gearing 2 slows down, and the crank rocking arm 31 that drives crank mechanism 3 is done the circumference rotation, and crank rocking arm 31 drives U type chute rocking arms 32 and swings up and down around bracing frame 4 tween drive shafts, drives 33 side-to-side movements of windscreen wiper rocking arm, finally drives windscreen wiper sheet 5 and swings.

These two motors 5 adopt micro controller system 6 controls, and principle is as shown in Figure 2, and under the control of micro controller system 6, two windscreen wiper sheets 5 of two motor 1 difference independent drive satisfy the vehicle wiper all functions.

The utility model is owing to adopt two lower-powered motor via reducer structures to drive the Windshield Wiper crank; Drive two wiper sheets; Removed original four-bar linkage, the structure letter is gathered, and has reduced installing space; The special-purpose wiper work of medium and heavy truck of prior art and motor omnibus that overcome simultaneously is unreliable, unstable, be easy to occur the deficiency of deadlock phenomenon, thereby improved functional reliability and stability.

The protection domain of non-so limitation the utility model so use the equivalence techniques variation that the utility model specification sheets and diagramatic content do such as, all is contained in the protection domain of the utility model.
