Abstract

The utility model discloses a shock-absorption connecting flange, which is characterized in that shock absorbers (2) communicated with each other are arranged in an annular inner cavity of an axle sleeve of a driven disc (3) and a cavity between two inner end faces of the driving disc and the driven disc at an interval in a bore of the driving disc (1). When in operation, an output shaft of an engine is elastically connected with a transmission shaft of a heavy-duty automobile fan clutch through the shock-absorption connecting flange. Higher rotation torque is generated when a fan clutch is started by the engine instantly, the shock absorbers communicated with each other between the bore of the driving disc and the axle sleeve of the driven disc and between two inner end faces of the driving disc and the driven disc deform elastically instantly, so that flexible shock absorption function onto instant start of the engine is realized effectively, abrasion and noise due to impact vibration generated by connecting components of the engine and the electromagnetic fan clutch are reduced obviously, and service lives of the engine and the electromagnetic fan clutch are both prolonged.

Description

A kind of bumper and absorbing shock adpting flange

(1) technical field: the utility model relates to power engine output terminal and drive unit flange connecting; Be specifically related to a kind of bumper and absorbing shock adpting flange.

(2) background technique: prior art medium power machine output terminal and drive unit flange connecting are to be rigidly connected as engine output shaft and heavy-duty car fan clutch transmission shaft flange connecting.Because the driving torque that produces during the work of engine output shaft moment startup fan clutch is very big, connected element generation impact endurance test shock wearing and tearing and noise to motor and fan clutch are also bigger, use the working life of having reduced both under the long-term work situation.

(3) summary of the invention: at the deficiency of above-mentioned prior art existence, the purpose of this utility model is to provide a kind of bumper and absorbing shock adpting flange, be intended to reduce the power engine output terminal and be connected impact endurance test shock wearing and tearing and the noise that produces with drive unit, to realize improving both working life.

For achieving the above object, the technical solution of the utility model is to realize like this, sort buffer damping adpting flange is to be in the driving disc hole in the annular cavity and the annular cavity between master and slave Moving plate two interior edge faces that spacing is equipped with the driven disc axle sleeve, is communicated with the bumper and absorbing shock body.

When implementing technique scheme, it is to be made of rubber material that the utility model is selected described bumper and absorbing shock body.

The utility model is by taking said structure, during work, engine output shaft is connected with the transmission shaft elasticity of heavy-duty car fan clutch by the bumper and absorbing shock adpting flange, when motor moment starts fan clutch work and rotates moment of torsion when very big, by the master, the hole of driven disc, between the axle sleeve and main, the immediate elastic deformation that the loop buffer shock reducing structure that is communicated with between driven disc two interior edge faces produces, played flexible buffer cushioning effect effectively to motor moment startup, the connected element that has reduced significantly motor and fan clutch produces impact endurance test shock wearing and tearing and noise, has reached the working life of improving both.

(4) description of drawings: Fig. 1 is a kind of embodiment's of the utility model a sectional view;

Fig. 2 is the left view of Fig. 1.

(5) embodiment: Fig. 1-shown in Figure 2.Sort buffer damping adpting flange, it is to be in driving disc 1 hole in the annular cavity and the annular cavity between master and slave Moving plate two interior edge faces that spacing is equipped with driven disc 3 axle sleeves, injection moulding is communicated with the bumper and absorbing shock body 2 (Fig. 1, shown in Figure 2) that rubber material constitutes.During work, heavy-duty car engine output shaft and driving disc of the present utility model 1 join, and the endoporus of driven disc 3 axle sleeves links to each other with the output shaft of heavy-duty car fan clutch.When motor moment starts fan clutch work and rotates moment of torsion when very big, be communicated with the immediate elastic deformation that the rubber bumper and absorbing shock body 2 that is connected produces between hole by master and slave Moving plate, the axle sleeve and between master and slave Moving plate two interior edge faces, played the effect to the damping of motor moment startup flexible buffer effectively, the connected element that has reduced significantly motor and electromagnetic fan clutch produces impact endurance test shock wearing and tearing and noise.According to different fields of employment, described power engine also can be a motor, and its output terminal is connected with drive unit by the utility model, can realize the good effect of flexible buffer damping equally.

The above only is a preferred implementation of the present utility model.Be noted that for the person of ordinary skill of the art, under the prerequisite that does not break away from the principle of the invention, need not other technical characteristics that the process creative work just can be associated, can also make the modification and the improvement of some kinds of basic identical modes, realize essentially identical function and produce essentially identical effect, as for increasing the connectivity robustness of bumper and absorbing shock body, be provided with projection at the bore area and/or master and slave Moving plate two internal end surfaces of driving disc; Be provided with groove on driven disc axle sleeve surface.These variations should be considered as equivalent feature, all belong within the protection domain of the utility model patent.

Claims

1. bumper and absorbing shock adpting flange is characterized in that: be in driving disc (1) hole in the annular cavity and the annular cavity between master and slave Moving plate two interior edge faces that spacing is equipped with driven disc (3) axle sleeve, be communicated with bumper and absorbing shock body (2).

2. a kind of bumper and absorbing shock adpting flange according to claim 1 is characterized in that: described bumper and absorbing shock body is to be made of rubber material.
