Abstract
A water pump cover of a water-cooling motorcycle engine is provided, wherein a water outlet pipe (3) of a water pump is also arranged on a cover body (1), besides arranging a water inlet pipe (2) of the water pump on the cover body (1), and the water inlet pipe (2) and the water outlet pipe (3) are integrated with the cover body (1). After adopting the water pump cover of the utility model, the assembly structure of the water pump on a right crankshaft case cover is simplified as no needing to process mounting holes of a water outlet way and the water outlet pipe on the right crankshaft case cover, which not only greatly simplifies the assembly technology of the water pump, but also avoids water leakage, is more convenient for detaching in maintenance, and increases the quality reliability of the water pump.
Description
Technical field
The utility model relates to the pump part on the cooling motorcycle engine water, especially water pump cover.
Background technique
At present, the common assembling structure of cooling motorcycle engine water charging pump is as shown in Figure 1: mainly the water pump complement of being made up of water pump spindle 4, water pump body 5, water pump vane 6 and oil sealing, water seal is installed on the right crankcase cover 7, the intake pipe 2 of water pump, outlet pipe 3 are separately positioned on water pump cover 8 and the right crankcase cover 7, the outlet pipe 3 of water pump and right crankcase cover 7 be for dividing a body structure, and it is fixing during assembling to be that interference fit is pressed into.There is following defective in this structure:
1, right crankcase covers the water outlet that communicates with pumping line the inner need to be set, and the outlet pipe pilot hole accuracy of manufacturing that pumping line and right crankcase cover has relatively high expectations, relatively require great effort during assembling, thereby technology cost height;
2, different because of the material of pumping line and right crankcase cover, the quality problems of leaking appear in expansion coefficient difference at high temperature easily in the use;
3, in a single day occur leaking, the right crankcase cover that normally will have water pump complement during maintenance carries out integral replacing, maintenance is complicated, the cost height.
The model utility content
The purpose of this utility model provides a kind of water pump cover of cooling motorcycle engine water, leaks, keeps in repair complexity and the high problem of cost easily with the water pump that solves on the existing cooling motorcycle engine water.
For achieving the above object, the water pump cover of cooling motorcycle engine water described in the utility model, except the intake pipe that is provided with water pump on lid, the outlet pipe of water pump also is arranged on the lid.
The intake pipe and the outlet pipe of water pump all are arranged on the lid of water pump cover, need not to cover the mounting hole that processes water channel and outlet pipe, simplified water pump, reduced the hidden danger of quality that leaks at the assembly structure that right crankcase covers at right crankcase.
As a kind of preferred embodiment, it between intake pipe and outlet pipe and the lid overall structure of casting forming, so not only can reduce water pump assembly technology cost greatly, and avoided leaking of intake pipe and outlet pipe mounting hole place, mounting or dismounting are easier during maintenance, have improved the reliability of water pump.
Further, above-mentioned intake pipe is connected in the central authorities at lid top, and outlet pipe is connected in the end near lid.After water pump complement was assemblied on the motor, the water intake on the lid was over against the center of water pump vane, and water outlet is over against the tangential direction of water pump vane.During work, water enters over against the water pump vane center that the tangential direction from water pump vane is thrown out of behind the pump chamber, can reduce energy loss like this, raises the efficiency.
The technique effect that the utility model is obtained is: can significantly reduce the assembly technology cost of whole water pump on motor, avoid the quality problems of leaking, operational safety height.
Description of drawings
Fig. 1 is traditional assembly structure schematic representation of cooling motorcycle engine water charging pump;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the plan view of Fig. 2;
Fig. 4 is the assembly structure schematic representation of the utility model on cooling motorcycle engine water;
Among the figure: 1. lid; 2. intake pipe; 3. outlet pipe; 4. pump shaft; 5. water pump body; 6. water pump vane; 7. right crankcase cover; 8. water pump cover; 9. pump chamber.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As Fig. 2, shown in Figure 3, a kind of water pump cover of cooling motorcycle engine water, except the intake pipe 2 that is provided with water pump on lid 1, the outlet pipe 3 of water pump also is arranged on the lid 1, and intake pipe 2 and outlet pipe 3 is the overall structure of casting forming with lid 1.Owing to need not to cover the mounting hole that processes water channel and outlet pipe at right crankcase, simplified the assembly structure that water pump covers at right crankcase, so not only can reduce the assembly technology cost of water pump greatly, and avoid leaking, mounting or dismounting are easier during maintenance, have improved the reliability of water pump.
As shown in Figure 4, lid 1 inner side surface is a concave arc shape, and the concave arc shape die cavity of lid 1 constitutes the part of water pump pump chamber 9, and intake pipe 2 is connected in the central authorities at lid 1 top, and outlet pipe 3 is connected in the end near lid 1.Lid 1 is after water pump complement is assemblied on the motor, water intake on the lid 1 is over against the center of water pump vane 6, water outlet is over against the tangential direction of water pump vane 6, during work, water enters pump chamber 9 back tangential direction from water pump vane 6 and is thrown out of over against water pump vane 6 centers, can reduce energy loss like this, raise the efficiency.
