Abstract

The utility model discloses a water pump arranging structure for a motorcycle water-cooling engine, comprising a water cooling engine and a water pump assembly; the utility model is characterized in that the water pump assembly positioned in the lower front of the clutch, is arranged in the inner side of the right tank cover of the engine; an included angle Alpha between a connection line of the two axial centers of the water pump and the clutch and the vertical center of the clutch axial center is 0 to 25 degrees; the water pump driving gears arranged in the same shaft as the water pump impeller are meshed with the clutch gears for the water cooling engine. The utility model has the advantages of reasonable arranging structure, large arranging space, compact structure, beautiful profile, being easy for arranging and repairing; thereby the utility model can be run in high rotational speeds variably and the large volume of water of the water pump is output with good cooling effect.

Description

Motorcycle water-cooled formula engine water pump mounting structure
Technical field
The utility model relates to motorcycle engine, and what relate in particular to is the mounting structure of the water pump of motorcycle water-cooled formula motor.
Background technique
The water pump of motorcycle water-cooled formula motor is installed three kinds of modes usually, as shown in Figure 3, a kind of is the A place that water pump complement is installed in motor 1, by crank-driven, the shortcoming of this mounting structure is: the water pump mounting point is near cylinder block, so the structure more complicated, the position is higher, and the lubricating condition of water pump is bad; In addition, be subjected to the oil filter structural limitations, the water yield of pump also is difficult to improve, and causes the cooling effect of motor poor; From the motor outward appearance, make the outward appearance of motor also relatively more mixed and disorderly, installation and maintenance are also inconvenient.
Similar alternative arrangements is the B place that water pump complement is installed in motor 1, drive by oil pump, this mounting structure is owing to be subjected to the restriction of oil pump, rotating speed is lower, make the water yield of pump less, cooling effect is relatively poor, and makes oil pump stressed bigger, also influenced the reliability of oil pump work, its installation and maintenance are same inconvenient.
Also having a kind of mounting type is water pump complement to be installed in the C place and by the clutch teeth wheel drive, though the problem that this mode has avoided above-mentioned dual mode to exist, but because motor C place is commonly used to the installation foot starting drive, as be used for installing water pump and then will cancel the pin starting drive, motor cannot start when causing the electric starter cisco unity malfunction, awkward problem occurs.
The model utility content
The problems referred to above at existing motorcycle water-cooled formula engine water pump mounting structure existence, the purpose of this utility model is to provide a kind of novel motorcycle water-cooled formula engine water pump mounting structure, this novel mounting structure position is reasonable, compact structure, installation, maintenance is convenient, good cooling results.
In order to achieve the above object, the motorcycle water-cooled formula engine water pump mounting structure that the utility model provides, comprise water-cooled engine and water pump complement, water pump complement is installed in the inboard of the right case lid of motor and is positioned at the inferoanterior of clutch, the angle α of the vertical centre in water pump complement and clutch two axle center lines and clutch axle center is 0~25 degree, with the gear of the coaxial mounted water pump driving of water pump vane and the clutch gear engagement of water-cooled engine.
The motorcycle water-cooled formula engine water pump mounting structure that the utility model provides is because water pump complement is installed in water-cooled engine clutch inferoanterior, and by the clutch teeth wheel drive, away from engine cylinder body and avoided the pin starting drive, so this mounting structure position is reasonable, installing space is big, compact structure, the outward appearance novelty, and be convenient to install and maintenance, the rotating speed of water pump is higher and adjustable, make the conveying water yield of pump big, good cooling results.
Description of drawings
Fig. 1 is a motorcycle water-cooled formula engine water pump mounting structure schematic representation of the present utility model;
Fig. 2 is the E-E broken line sectional view of Fig. 1;
Fig. 3 is known motorcycle water-cooled formula engine water pump mounting structure schematic representation.
Embodiment
Below in conjunction with the drawings and specific embodiments motorcycle water-cooled formula engine water pump mounting structure of the present utility model is described further.
Embodiment 1
As Fig. 1 and shown in Figure 3, water pump complement 3 is installed on the right case lid of motor at inferoanterior D place of clutch of water-cooled engine 1, and the angle α of the vertical centre in water pump complement and clutch two axle center lines and clutch axle center 0 spends.In conjunction with shown in Figure 2, water pump complement 3 comprises water pump cover 31, water pump vane 32, bearing, axle 38, outlet pipe 35, intake pipe 33, seal arrangement 37, on the right case lid 11 of motor, there is one groove is installed, seal arrangement 37 grades of water pump complement are inlaid in the groove together with installation sleeve etc., and water pump cover 31 is fixed on the right case lid of motor 11 by three screws 4.The axle 38 of water pump complement is installed in the mode vertical with clutch gear 12.The axle head and the impeller 32 of the water pump complement in the right case lid 11 of motor are coaxially installed with water pump driving gear 39, water pump driving gear 39 and clutch gear 12 engagements.Impeller 32 is positioned at the cavity that water pump cover 31 forms, intake pipe 33 be positioned on the water pump cover 31 and with water pump cover be one, outlet pipe 35 is positioned on the right case lid 11 of motor.This setting-in structure makes whole engine structure comparatively compact, good sealing effect and maintenance, easy for installation.For ease of being connected with the water-in and water-out flexible pipe, there is tapered annular projection 34,36 intake pipe 33 and outlet pipe 35 ends.
Embodiment 2
As Fig. 1 and shown in Figure 3, water pump complement 3 is installed on the right case lid of motor at inferoanterior D place of clutch of water-cooled engine 1, and the angle α of the vertical centre in water pump and clutch two axle center lines and clutch axle center 25 spends.Identical among other structure and the embodiment 1.
Embodiment 3
As Fig. 1 and shown in Figure 3, water pump complement 3 is installed on the right case lid of motor at inferoanterior D place of clutch of water-cooled engine 1, the angle α of the vertical centre in water pump and clutch two axle center lines and clutch axle center is 10 degree, this position belongs to a better position, and it is the most convenient to install and keep in repair.Identical among other structure and the embodiment 1 in the present embodiment.
Embodiment 1,2,3 described mounting points are away from the cylinder block 2 of motor and avoided the mounting point of pin starting drive, so installing space is bigger, install and keep in repair more convenient.Because water pump complement 3 is embedded in the right case lid 11 of motor substantially, so compact structure, outward appearance are novel neat.The running of pump is by the clutch teeth wheel drive, makes its rotating speed higher, and the pump water yield is big and adjustable, has improved the cooling effect of water-cooled.
