Abstract

The utility model provides a novel exhaust brake valve free of damaging engine, which comprises a valve body, a valve door, a valve door shaft, a cylinder and a push rod, wherein the valve door is supported in inner cavity of the valve body by the valve door shaft, the cylinder is connected with the manipulation end of the valve door shaft by the push rod, the valve door shaft is arranged eccentrically in the valve body. In the utility model the valve door and the valve door shaft adopts eccentric structural arrangement in the valve body, when braking, the valve door can be closed, when the backpressure of engine is high up to a certain value, a certain rotary torque can be generated as the upper and lower portions of the valve door are subjected to different pressures, thereby opening the valve door of the exhaust brake valve, after two torques reach balance, the backpressure can be always stabilized at appropriate value, so as to reduce the abrasion of engine resulted from ultrahigh backpressure, thereby prolonging service life of engine, simultaneously the utility model can effectively utilize the engine to absorb kinetic energy of the engine so as to realize continuous brake.

Description

Not damaged motor novel exhaust brake valve

Technical field

The utility model relates to a kind of not damaged motor novel exhaust brake valve.

Background technique

At present, in the car load braking system, except skidding, also often adopt the exhausting waste gas pipeline that kills engine, make motor set up back pressure, the kinetic energy that utilizes motor to absorb motor realizes continuing the complemental brake system of braking.The exhaust braking valve that the exhausting waste gas pipeline that kills engine is commonly used, what wherein valve and valve shaft adopted in valve body is symmetric arrangement, adopt this structural configuration, if exhaust braking valve good braking effect, just motor absorbs under the effective situation of the kinetic energy of motor, can in motor, produce sizable back pressure, this back pressure generally can reach more than the twice of engine back pressure specified value, can produce big influence to the parts of motor in this case, be very easy to damage motor, influence the life-span of motor.

Summary of the invention

The utility model provides a kind of not damaged motor novel exhaust brake valve, can effectively solve because engine back pressure is excessive, and caused motor is impaired, reduces the problem of engine life.

For solving the problems of the technologies described above, the technical solution of the utility model is as follows: comprise valve body, valve, valve shaft, cylinder, push rod, valve is supported on by valve shaft in the inner chamber of valve body, and cylinder is connected with the manipulatable end of valve shaft by push rod, and wherein valve shaft adopts arranged off-centre in valve body.

Beneficial effect:

Use not damaged motor novel exhaust brake valve described in the utility model, valve and valve shaft adopt eccentric structure to arrange in valve body, can be when braking, the valve of exhaust braking valve kills engine, engine back pressure is high during to numerical value definitely, owing to the pressure that the valve top and the bottom are suffered is different, can produce running torque definitely, thereby open the valve of exhaust braking valve, after two kinds of moments reached balance, back pressure can be stabilized on the suitable numerical value always like this, and it is impaired to reduce the too high caused motor of back pressure, prolong the working life of motor, simultaneously all right more efficient use motor absorbs the kinetic energy of motor and realizes continuing braking.

Fig. 2 is a valve inner structural representation of the present utility model.

Embodiment

The utility model not damaged motor novel exhaust brake valve comprises valve body 1, cylinder 4, push rod 5 as shown in Figure 1.

The valve inner of model utility not damaged motor novel exhaust brake valve comprises valve 2, valve shaft 3 as shown in Figure 2, and valve 2 is supported on by valve shaft 3 in the inner chamber of valve body 1, and valve shaft 3 is along the radial arrangement of the inner chamber of valve body 1; Valve shaft 3 adopts eccentric structure to arrange that promptly the inner chamber axis of the axis of valve shaft 3 and valve body 1 is non-intersect, and suitable distance is arranged between the two axial lines in valve body 1.

Use not damaged motor novel exhaust brake valve described in the utility model, during braking, the valve of exhaust braking valve kills engine, engine back pressure is high during to numerical value definitely, owing to the pressure that the valve top and the bottom are suffered is different, can produce running torque definitely, when the moment of moment greater than cylinder and rocking arm generation, thereby open the valve of exhaust braking valve, back pressure is stabilized on the suitable numerical value always.

Claims

1. not damaged motor novel exhaust brake valve, comprise valve body, valve, valve shaft, cylinder, push rod, valve is supported on by valve shaft in the inner chamber of valve body, and cylinder is connected with the manipulatable end of valve shaft by push rod, it is characterized in that: described valve shaft adopts arranged off-centre in valve body.
