Description
Technical field
The utility model relates to a kind of auto pump, and more particularly, it relates to a kind of water pump casing for vehicle.
Background technique
In the cylinder body of motor car engine, there is the water channel of many Cooling Water circulations, radiator with being placed in automotive front, is commonly called as water tank, is connected by water pipe, form a large water circulation system, at the upper water-out mouth of motor, a water pump is housed, is driven by fan belt, hot water in engine cylinder-body water channel is pumped, cold water is pumped into.A thermostat is also had on the side of water pump, when automobile just starts and cold car time, do not open, make cooling water without water tank, only at motor Inner eycle, be commonly called as short circle, when the temperature of motor reaches more than 95 degree, just open, in-engine hot water is pumped to water tank, cold wind during automobile front driving blows over water tank, takes away heat, this wherein water pump play vital effect.
And for auto pump, its weight should be alleviated as much as possible, and cost-saving, reduce energy consumption, ensure higher intensity again simultaneously.
At present, application number be 201220131837.6 Chinese patent disclose a kind of water pump casing for vehicle, it comprises pump shaft hole and spiral case, the mounting surface of housing is plane, its periphery has shell bores, and pump shaft hole outer wall circumferential distribution has stiffening rib, and is connected to the outer wall of spiral case.Although this pump case improves the intensity of the pump housing by the stiffening rib being arranged on pump shaft hole outer wall, cost-saving, but it is well-known, the pump housing works in automobile engine cylinder-body, its working strength and temperature variation are all comparatively large, and not only will ensure the intensity at pump shaft hole place, the intensity of its entirety is also very important, particularly mounting hole is at galloping, is easy to the phenomenon occurring crumbling during pump working.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of housing bulk strength good water pump casing for vehicle.
For achieving the above object, the utility model provides following technological scheme: a kind of water pump casing for vehicle, comprise for installing the pump shaft hole of pump shaft, the spiral case of watering cycle, described pump shaft hole forms boss to housing extension, the mounting surface of described housing is plane, the circumferential distribution of described housing has mounting hole, and the outer wall circumferential distribution of described boss has stiffening rib and is connected to the outer wall of spiral case, and described stiffening rib extends to mounting hole always from the outer wall of spiral case and is connected as one with mounting hole.
By above-mentioned setting, the maximum pump shaft hole of working strength ensure that its intensity due to the effect of the stiffening rib of its periphery, thus the wall thickness at pump shaft hole place can be alleviated, cost-saving, by stiffening rib being connected to volute outer wall and extending to mounting hole place, also ensure that the intensity of spiral case simultaneously, prevent spiral case from bursting apart, the more important thing is that stiffening rib and mounting hole are connected as one, greatly strengthen the intensity of mounting hole, effectively prevent mounting hole from collapsing angle, the overall generation damaged, corresponding for water pump casing for vehicle key position is connected as a single entity by stiffening rib, can not only effectively prevent it from damaging, and improve the intensity of housing entirety.
Preferably, described casing peripheral is distributed with outwardly lug, and described mounting hole site is on lug.
By above-mentioned setting, lug is not directly connected with spiral case, and mounting hole site can ensure when mounting hole surprisingly bursts apart on lug, can not have influence on sealing and its bulk strength of spiral case, ensures that auto pump still can normal operation.
Preferably, the lug away from side, pump shaft hole is provided with projection, and described projection is wrapped in the sidewall of mounting hole.
By above-mentioned setting, because its intensity of lug away from pump shaft hole place is poor, and it extends out separately, and the mounting hole on it very easily crumbles due to the effect of torsion or vibrations, therefore utilizes projection to comprise the sidewall of mounting hole, ensures the intensity of mounting hole.
Preferably, described housing is also provided with spilled water hole, described spilled water hole is connected with stiffening rib.
By above-mentioned setting, support the bearing grease lubrication of pump shaft, therefore to prevent cooling liquid from leaking into lubricating grease and cause lubricating grease emulsification, also to prevent the leakage of lubricating grease simultaneously, spilled water hole is between seal cage and bearing, once there be cooling liquid to leak through water seal, can release from spilled water hole, destroy bearing lubrication to prevent cooling liquid from entering bearing bore and cause parts corrosion, bulk strength simultaneously in order to not allow lofty the arranging of spilled water hole affect housing, it be connected with stiffening rib, namely stiffening rib is wrapped in spilled water hole, ensures the intensity of spilled water hole and housing.
Compared with prior art, the beneficial effects of the utility model are: corresponding for water pump casing for vehicle key position is connected as a single entity by stiffening rib, can not only effectively prevent it from damaging, and improve the intensity of housing entirety.

Embodiment
For making the object of the utility model embodiment, technological scheme and advantage clearly, the utility model being done describe clearly and completely further below with reference to accompanying drawings.Obviously, described embodiment is section Example of the present utility model, instead of whole embodiments.Based on described embodiment of the present utility model, the every other embodiment that those of ordinary skill in the art obtain under without the need to the prerequisite of creative work, belongs to the scope of the utility model protection.
Water pump casing for vehicle as shown in accompanying drawing 1,2, comprise for installing the pump shaft hole 2 of pump shaft, the spiral case 3 of watering cycle, described pump shaft hole 2 forms boss 4 to housing 1 extension, the mounting surface of described housing 1 is plane, the circumferential distribution of described housing 1 has mounting hole 5, outer wall 10 circumferential distribution of described boss has stiffening rib 6 and is connected to the outer wall 11 of spiral case, and described stiffening rib 6 extends to mounting hole 5 outer wall from the outer wall 11 of spiral case always and is connected as one with mounting hole 5.The maximum pump shaft hole 2 of working strength ensure that its intensity due to the effect of the stiffening rib 6 of its periphery, thus the wall thickness at pump shaft hole 2 place can be alleviated, cost-saving, by stiffening rib 6 being connected to the outer wall 11 of spiral case and extending to mounting hole 5 place, also ensure that the intensity of spiral case 3 simultaneously, prevent spiral case 3 from bursting apart, the more important thing is that stiffening rib 6 and mounting hole 5 are connected as one, greatly strengthen the intensity of mounting hole 5, effectively prevent mounting hole 5 from collapsing angle, the overall generation damaged, corresponding for water pump casing for vehicle 1 key position is connected as a single entity by stiffening rib 6, can not only effectively prevent it from damaging, and improve the intensity of housing 1 entirety.
