Abstract
The invention provides a blimp of an automobile engine cylinder cover. The blimp is characterized in that a blimp body (2) is installed above a cylinder cover (1), the whole cylinder cover (1) is covered by the blimp body (2), and a lining (3) is arranged between the blimp body (2) and the cylinder cover (1). The blimp of the automobile engine cylinder cover is further characterized in that a hollow cavity (5) which is provided with reinforcing ribs (4) is formed in one end of the blimp body (2). The blimp of the automobile engine cylinder cover is capable of achieving the effects of sound insulation and noise reduction and avoiding generation of sympathetic vibration of the blimp body and the engine.
Description
Technical field
This invention relates to a kind of automobile panel, particularly a kind of sound-insulating cover of cylinder cover of automobile engine that can sound insulation and noise reduction.
Background technique
On motor car engine top; attractive in appearance and do not allow foreign matter fall into engine interior for product; generally all can add tectum structure; this tectum structure plays the effect of protection engine interior foreign; but strengthen because vibrations can cause noise during vehicle operating, noise stains the travelling comfort that can affect vehicle complete vehicle.Present existing engine cylinder cap major part does not possess the function of sound insulation and noise reduction, thereby and the cylinder head of minority band sound-insulating cover can produce the effect that resonance have a strong impact on sound insulation and noise reduction with motor.
Summary of the invention
For above deficiency, the purpose of this invention is to provide a kind of sound-insulating cover that can effectively reduce the cylinder cover of automobile engine of noise pollution, be the hollow shape chamber that increases on the sound-insulating cover body with stiffening rib, can effectively reduce the resonance of sound-insulating cover body and motor, improve the effect of noise reduction.
Technological scheme of the present invention is achieved in the following ways: the sound-insulating cover of cylinder cover of automobile engine, comprise the sound-insulating cover body that is arranged on the cylinder head top, described sound-insulating cover body wraps whole cylinder head, be provided with liner between sound-insulating cover body and cylinder head, it is characterized in that: also be provided with the hollow shape chamber with stiffening rib on described sound-insulating cover body.
The top-down material of described liner is followed successively by polypropylene, rubber, felt and nonwovens, with the effect that improves sound insulation and noise reduction and play heat insulation effect.
It is inboard that described liner is fixedly mounted on the sound-insulating cover body.
Beneficial effect: the present invention compared with prior art can play the effect of sound insulation and noise reduction effectively, and can avoid sound-insulating cover body and motor to produce resonance, thereby effectively improves the effect of noise reduction.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is stiffening rib enlarged view of the present invention.
Fig. 3 is the structural representation of liner of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of sound-insulating cover of cylinder cover of automobile engine, comprise the sound-insulating cover body 2 that is arranged on cylinder head 1 top, sound-insulating cover body 2 is wrapped in whole cylinder head 1, be provided with liner 3 between sound-insulating cover body 2 and cylinder head 1, sound-insulating cover body 2 one ends are provided with the hollow shape chamber 5 with three stiffening ribs 4.
Being known by Fig. 2, is stiffening rib enlarged view of the present invention.Increase the resonance that hollow shape chamber 5 with stiffening rib 4 can reduce sound-insulating cover body 2 and motor effectively on sound-insulating cover body 2, thereby improve the effect of noise reduction.
Being known by Fig. 3, is the structural representation of liner of the present invention.Described liner 3 is fixedly mounted on sound-insulating cover body 2 inboards by the pad of blooming, and the top-down material of liner 3 is followed successively by polypropylene 3-1, rubber 3-2, felt 3-3 and nonwovens 3-4.Further improve the effect of sound insulation and noise reduction and play heat insulation effect.
Claims (3)
1. the sound-insulating cover of cylinder cover of automobile engine, it is characterized in that: comprise the sound-insulating cover body (2) that is arranged on cylinder head (1) top, described sound-insulating cover body (2) wraps whole cylinder head (1), be provided with liner (3) between sound-insulating cover body (2) and cylinder head (1), it is characterized in that: described sound-insulating cover body (2) one ends are provided with the hollow shape chamber (5) of band stiffening rib (4).
2. the sound-insulating cover of cylinder cover of automobile engine according to claim 1, it is characterized in that: the top-down material of described liner (3) is followed successively by polypropylene (3-1), rubber (3-2), felt (3-3) and nonwovens (3-4).
3. the sound-insulating cover of cylinder cover of automobile engine according to claim 1 is characterized in that: described liner (3) is fixedly mounted on sound-insulating cover body (2) inboard.
