Abstract
The utility model relates to the field of automobile engines, in particular to the field of water pumps. The water pump is as follows: a belt wheel is arranged on a shaft neck of a water pump shaft, which extends to the outer side of a pump body, a fixing hole is arranged on the pump body positioned beside the water pump shaft at the end, a gap part corresponding to the fixing hole is arranged on the belt wheel, and a connecting part penetrates the gap part and the fixing hole so as to constitute detachable plug-in mounting and fit and constitute axial limiting fit with the belt wheel. Due to the adoption of the technical scheme, when a fan clutch is mounted or detached, the connecting part is inserted in the fixing hole and a through hole, thereby fixing the belt wheel, simultaneously preventing the rotation of the water pump shaft relative to the pump body and facilitating the mounting of the fan clutch.
Description
Technical field
The utility model relates to the motor car engine field, is specifically related to the water pump field.
Background technique
The fan clutch of motor car engine charging pump is by being threaded on the water pump spindle, and when installation and removal, the housing of the relative water pump of water pump spindle meeting relatively rotates, and is uncontrollable, brought very big difficulty to installation and removal, causes inefficiency.
Summary of the invention
The purpose of this utility model provides a kind of water pump of being convenient to the installation and removal of water pump fan clutch.
For achieving the above object, the utility model has adopted following technological scheme: a kind of water pump, the axle journal that water pump spindle extends to the pump housing outside is provided with belt wheel, be positioned on the pump housing of this end water pump spindle side fixed hole is set, belt wheel is provided with and the corresponding vacancy of fixed hole portion, link runs through vacancy portion and fixed hole, constitutes dismountable plug-in mounting cooperation and constitute axial limiting with belt wheel to cooperate.
Owing to adopt above technological scheme, when the fan clutch installation or removal, link is inserted in fixed hole and the through hole, prevented when having fixed belt wheel that the relative pump housing of water pump spindle from rotating, and is convenient to the installation of fan clutch.
Description of drawings
Fig. 1 is the structural representation of water pump;
Fig. 2 is that the A-A of Fig. 1 is to sectional view;
Fig. 3 is the structural representation that the water pump of link is installed;
Fig. 4 is the structural representation of the pump housing.
Embodiment
A kind of water pump, the axle journal that water pump spindle 10 extends to the pump housing 20 outsides is provided with belt wheel 30, be positioned on the pump housing 20 of these end water pump spindle 10 sides fixed hole 21 is set, belt wheel 30 is provided with and the corresponding vacancy of fixed hole 21 portion 31, link 50 runs through vacancy portion 31 and fixed hole 21, constitute dismountable plug-in mounting cooperation and constitute axial limitings and cooperate with belt wheel 30, during the installation and removal fan clutch, link 50 is placed in vacancy portion 31 and the fixed hole 21, prevented that belt wheel from rotating with respect to the pump housing 20, prevented that further water pump spindle 10 from the pump housing 20 relative rotation taking place, fixed water pump spindle 10, be convenient to the installation and removal of fan clutch, during normal working link 50 taken out, do not influence the proper functioning of water pump.
Further, the axle journal of described water pump spindle 10 is provided with flange plate 40, and belt wheel 30 is connected as a single entity with flange plate 40, and flange plate 40 is provided with and the corresponding vacancy of fixed hole 21 portion 41.Belt wheel 30 and the concrete Placement of flange plate 40 can be that the card of flange plate 40 adopts bolt to be connected with the web of belt wheel 30, because the present compactness more that engine structure is required, cause many Water-pump belt wheels 30 to influence the installation of bolt of water, need to remove earlier belt wheel 30, reinstall belt wheel 30 again after being installed to water pump on the cylinder body, link 50 is inserted in vacancy portion 31,41 and the fixed hole 21, make belt wheel 30 fixing, be convenient to the installation of belt wheel 30 with respect to flange plate 40.
Further again, described fixed hole 21 is opened in boss 22 places on the pump housing 20, guarantees to simplify when the link 50 and the pump housing 20 have enough junction surfaces the structure of the pump housing 20, and material is saved in weight reduction.
The axis of the axis of described fixed hole 21 and water pump spindle 10 parallels, and adopts this structure to be convenient to fixed processing hole 21 and vacancy portion.
Described link 50 is the cylinder backing pin, because the cylinder backing pin is a standard piece, need not other processing, saves user cost.
The side of described water pump spindle 10 axially symmetry two fixed holes 21 are set, make the fixing more firm of link 50.
Further, described vacancy portion 31,41 is a through hole, and the diameter of axle of aperture and link 50 matches, and is convenient to processing when satisfying usage requirement.
