Description
Technical field
The invention belongs to technical field of engines, specifically, is a kind of new design about cooling engine for motor cycle water charging pump mounting type.
Background technique
Fig. 1, Fig. 2 is respectively the structural representation and the mounting type figure of existing cooling engine for motor cycle water charging pump, water pump is mainly by water pump body 1 as can be seen from Figure, water pump cover 2, water pump spindle 3, impeller 4 and water pump gear 5 are formed, water pump is installed in the crankcase right side and covers, by crank-driven (also useful oil pump or clutch teeth wheel drive), attachment face between water pump body 1 and the right case lid is perpendicular to the shaft axis of water pump spindle 3, connecting bolt is with water pump cover 2 during assembling, water pump body 1 sockets fixing with right case lid, because water pump gear 5 is bigger than water pump body 1 external diameter, after wanting earlier water pump to be installed to earlier on the right case lid of motor during assembling, be installed on the motor with right case lid again, install inconvenient.Equally,, after earlier water pump to be pulled down together with right case lid, again water pump is separated from right case lid,, existed inconvenient problem equally to keep in repair accordingly if water pump breaks down when needing repairing.
In addition, because the water outlet and the water outlet 8 of pump chamber 6 misplace each other, the water that comes out from pump chamber 6 needs twice change direction could flow out water pump, the flow resistance of current is big, the water velocity that enters engine cylinder-body is low, makes the cooling effect of motor poor so on the one hand, on the other hand the water pump so the long-term work under high speed conditions of having to, make the lost of life of water pump easily, reliability reduces.
Summary of the invention
The objective of the invention is provides a kind of water pump that is installed on the engine cylinder body in order to overcome above-mentioned deficiency, makes the installation of water pump and keeps in repair more convenient.
For achieving the above object, the water pump that is installed on the motorcycle water-cooled engine cylinder block provided by the invention, have water pump body, water pump cover, water pump spindle, impeller and water pump gear, water pump cover is installed on the water pump body end face to form pump chamber, being connected with pump chamber of water pump into and out of water channel, the attachment face that matches with engine cylinder-body on the described water pump body is parallel to the shaft axis of water pump spindle, is used for the center line of the bolt hole that links to each other with engine cylinder-body on the water pump body perpendicular to described attachment face.
Water pump among the present invention is installed on the engine cylinder-body, and water pump gear is driven by timing chain.The casing that will hold water pump gear is assemblied in the connection bearing that forms water pump one end on the water pump body, like this water pump just can the integral body realization and engine cylinder-body between dismounting, install and keep in repair very convenient; Or above-mentioned casing all-in-one-piece is arranged on the engine cylinder-body, only need on casing, to be provided with a case lid bigger slightly than water pump gear, open case lid when installing and keeping in repair water pump gear is carried out dismounting, compare with the mounting structure of existing cooling engine for motor cycle water charging pump, operate also to make things convenient for, much laborsaving.In addition, this mounting type can make the cooling water channel direct and on the engine cylinder-body of the water outlet on the water pump communicate, and need not connect component such as water pipe clip, has reduced cost.
Above-mentioned water pump body preferably is set with the bearing that is housing structure corresponding to an end of water pump gear, and water pump gear is positioned at the cavity of this bearing, also is provided with the bolt hole that links to each other with engine cylinder-body on the bearing.Bearing is connected with engine cylinder-body with water pump body is whole, thereby realizes the dismounting of water pump integral body.
As further improvement, above-mentioned water outlet is craspedodrome passage and the radially waterexit end that is right against impeller.Flow into the water of pump chamber under the centrifugal action of impeller from inlet channel, be thrown out of from the radially waterexit end of impeller, flow into straight then in the water outlet, current need not change direction in water outlet, be directly inputted in the cooling water chamber in the engine cylinder-body, thereby resistance is little.
The technique effect that the present invention obtains is: the installation of water pump and keep in repair more conveniently, and the water velocity that enters cylinder body under the identical condition of water pump vane rotating speed is fast, and the cooling effect of motor is better, low cost of manufacture.
