Description
Technical field
The utility model relates to the mounting structure of auto parts and components, specifically a kind of electric water pump mounting structure.
Background technique
Along with the pay attention to day by day of people to new-energy automobile, be extensively subject to people's concern as the pure electric automobile that can realize energy-saving and emission-reduction, domestic Ge great automobile vendor is also in positive research and development.Electric water pump is as the essential parts of electric vehicle, for cooling system and the warm air system of car load provide power source.Because the more traditional internal combustion locomotive of electric motor car has the advantage of low noise, low vibration, so that the NVH performance of electric water pump self is exaggerated aspect car load, the vibration of electric water pump and noise directly affect the NVH level of car load.
For this reason, CN 202746255 U disclose a kind of electric water pump fixing device, this fixing device comprises fixing gum cover and water pump mounting bracket, described fixing glue puts and is provided with water pump mounting hole and water pump mounting bracket mounting groove, and described water pump mounting bracket is arranged on fixing glue by water pump mounting bracket mounting groove and puts.This fixing device proposes for lack this problem of water pump fixed structure on vehicle body, and it is simple and reliable for structure, and angle of assembling capable of regulating can meet electric water pump fixing on real vehicle.Its fixing gum cover also has the effect of vibration damping, vibration isolation simultaneously, but rubber belongs to soft material after all, and under the long-time running vibration of water pump, water pump is easily deviate from from fixing gum cover, causes to install and loses efficacy.
Model utility content
The purpose of this utility model is to provide a kind of electric water pump mounting structure, makes the installation of electric water pump in rubber mounting reliable and stable.
The technical solution of the utility model is as follows: a kind of electric water pump mounting structure, comprise electric water pump, rubber mounting and mounting bracket, on rubber mounting, offer water pump mounting hole, one end of electric water pump is arranged in water pump mounting hole and its interference fit, one end of mounting bracket is fixedly connected with rubber mounting, water pump mounting hole place in rubber mounting exterior edge face is provided with retaining ring, the external diameter of this retaining ring is greater than the aperture of water pump mounting hole, and retaining ring is bolted on electric water pump, make the exterior edge face laminating of retaining ring and rubber mounting.
The inwall of described water pump mounting hole is provided with multiple tracks groove along the circumferencial direction in hole.
This programme solve due to electric water pump for a long time in vibrational state by retaining ring and and between rubber mounting, there is loosening problem, arranging of retaining ring stoped rubber mounting de-outward, strengthen the reliability that electric water pump is installed in rubber mounting, ensured the performance of rubber mounting vibration damping, vibration isolation effect.And by the soundness that groove is connected with electric water pump further to increase rubber mounting with adhesive stripe-coating being set at the inwall of water pump mounting hole.
Brief description of the drawings
Fig. 1 is axonometric drawing of the present utility model;
Fig. 2 is explosive view of the present utility model;
Fig. 3 is the axonometric drawing of the utility model with the rubber mounting of mounting bracket.
In figure: 1-rubber mounting; 2-mounting bracket; 4-electric water pump; 5-retaining ring; 10-water pump mounting hole; 13-groove; 51-flange; 52-stiffening rib; 53-bolt through-hole boss.
Embodiment
Below in conjunction with drawings and Examples, the utility model will be further described.
See a kind of electric water pump mounting structure shown in Fig. 1～3, rubber mounting 1 is placed between electric water pump 4 and mounting bracket 2, and the vibration of electric water pump 4 is subject to weakening of rubber mounting 1 and isolates, and can not be delivered on mounting bracket 2.Mounting structure for electric water pump 4 with rubber mounting 1, what this programme adopted is to offer water pump mounting hole 10 in certain thickness rubber mounting 1, one end of electric water pump 4 is arranged in water pump mounting hole 10 and its interference fit, water pump mounting hole 10 places in rubber mounting 1 exterior edge face are provided with retaining ring 5, the external diameter of this retaining ring 5 is greater than the aperture of water pump mounting hole 10, and retaining ring 5 is bolted on electric water pump 4, fitted in retaining ring 5 and the exterior edge face of rubber mounting 1.Adopt retaining ring 5 gear to lean against the exterior edge face of rubber mounting 1, rubber mounting 1 be limited between retaining ring 5 and electric water pump 4, can effectively prevent like this due to electric water pump 4 for a long time in vibrational state and and between rubber mounting 1, occur getting loose,
Further, the inwall of described water pump mounting hole 10 is provided with multiple tracks groove 13 along the circumferencial direction in hole, for coated with adhesive, make between the inwall of electric water pump 4 shells and water pump mounting hole 10 be connected more firm.
Further, the outer edge of described retaining ring 5 is provided with flange 51 outwardly to strengthen the soundness of structure, be evenly distributed with three bolt through-hole boss 53 for being connected with the outer end bolt of electric water pump 4 near inward flange flange place, between bolt through-hole boss 53 and retaining ring outward edge flange, be connected with stiffening rib 52 to increase the intensity of structure.
