Abstract
The utility model provides a horizontal four-stroke engine with an easily detachable engine oil filtering screen for motorcycles; on the engine, a filter chamber for engine oil is composed of an upper wall, a lower wall, a left wall, a right wall, a left wall, a right wall, an inner side wall and an outer side wall and is arranged at the bottom of a tank body of a right crankshaft; an oil inlet is arranged on the inner side wall; an oil outlet on the upper wall is communicated with the oil-in cavity of an engine oil pump; a barrel type filtering screen with a washer is arranged at the outer surface of an oil inlet; an oil drain screw nut is arranged on the lower wall; a spring is arranged between the oil drain screw nut and the washer. The barrel type filtering screen of the engine can be taken off by releasing the oil drain screw nut, and then cleaned or replaced. Since disassembly and assembly are easy, users can regularly clean or replace the filtering screen; the engine oil can stably enter the engine oil pump so that the friction components on the engine obtain long-term and good lubrication; thus, the service life of the engine is extended.
Description
Technical field
The utility model provides a kind of improved motorcycle horizontal four stroke engine.
Background technique
On the horizontal four stroke engine of existing motorcycle, in the machine oil filter chamber of right crankcase bottom flat filter screen is installed.This filter screen is closed in the engine body, is difficult for taking out.After long-time the use, impurity in the sump can be blocked filter screen, make machine oil not enter oil pump through the oil pump oil suction chamber smoothly, friction means such as cylinder body, camshaft, piston, piston ring, valve can not obtain effectively lubricating, thereby its wearing and tearing have been accelerated, reduced the working life of motor greatly, can cause the damage of motor when serious.Only after whole right crankcase cover is taken off from right crankcase, flat filter screen could be taken off and clean or change, very inconvenience.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of horizontal four stroke engine of motorcycle of quick detachable machine oil filter screen is provided, and cleans or changes easily the machine oil filter screen is taken off, thereby improve motor working life.
The utility model is to realize like this, the horizontal four stroke engine of the motorcycle of quick detachable machine oil filter screen, on described motor, the machine oil filter chamber that is made of upper wall, lower wall, Zuo Bi, You Bi, madial wall and outer side wall is arranged at the right crankcase bottom, filler opening is arranged on the madial wall, and the oil outlet on the upper wall communicates with the oil pump oil suction chamber, and the outside of filler opening is equipped with the barrel type filtering net of belt washer, the nut of draining the oil is installed on the lower wall, and draining the oil has spring between nut and the packing ring.
Adopt the horizontal four stroke engine of motorcycle of said structure,, just the barrel type filtering net can be taken off, clean or change, whole right crankcase cover need not be taken off from right crankcase by backing out the nut of draining the oil.Because dismounting, easy for installation, the user can regularly clean or change filter screen, and machine oil can stably enter oil pump, makes the friction means on the motor obtain long-term good lubrication, thereby has improved the working life of motor.
Description of drawings
Fig. 1 is the schematic representation of the right crankcase partial structurtes in the utility model.
Fig. 2 is its A-A sectional drawing.
Among the figure, the 1-nut of draining the oil, 2-spring, 3-barrel type filtering net, the right wall of 4-, 5-upper wall, 6-oil outlet, 7-oil pump oil suction chamber, 8-packing ring, 9-madial wall, 10-left side wall, 11-filler opening, 12-lower wall, 13-right crankcase, 14-outer side wall.
Embodiment
The embodiment who provides below in conjunction with accompanying drawing illustrates structure of the present utility model.
As shown in drawings, the horizontal four stroke engine of motorcycle of the quick detachable machine oil filter screen of the utility model, on described motor, right crankcase (13) bottom has by upper wall (5), lower wall (12), left side wall (10), right wall (4), the machine oil filter chamber that madial wall (9) and outer side wall (14) constitute, filler opening (11) is arranged on the madial wall (9), oil outlet (6) on the upper wall (5) communicates with oil pump oil suction chamber (7), the outside of filler opening is equipped with the barrel type filtering net (3) of belt washer (8), the nut of draining the oil (1) is installed on the lower wall (12), and draining the oil has spring (2) between nut and the packing ring (8).
Oil outlet tilts to communicate with the oil pump oil suction chamber.
During use, machine oil enters the machine oil filter chamber from filler opening, after oil outlet enters the oil pump oil suction chamber, by oil pump machine oil is delivered to each lubricant housings through the barrel type filtering net filtration.
When dismantling the barrel type filtering net, can earlier the nut of draining the oil be backed out, spring will take out from the screw on the lower wall (drain oil) together with the barrel type filtering net, can clean or change filter screen easily.During installation, with the outside of spring housing at the barrel type filtering net, send the machine oil filter chamber to, make packing ring be positioned at the outside of oil outlet, then, the nut of draining the oil screwed on again gets final product.
It is external to remove right crankcase, and other structure of the motor of the utility model is identical with the horizontal four stroke engine of existing motorcycle.
Claims (1)
1, the horizontal four stroke engine of the motorcycle of quick detachable machine oil filter screen, it is characterized in that, on described motor, right crankcase (13) bottom has by upper wall (5), lower wall (12), left side wall (10), right wall (4), the machine oil filter chamber that madial wall (9) and outer side wall (14) constitute, filler opening (11) is arranged on the madial wall (9), oil outlet (6) on the upper wall (5) communicates with oil pump oil suction chamber (7), the outside of filler opening is equipped with the barrel type filtering net (3) of belt washer (8), the nut of draining the oil (1) is installed on the lower wall (12), and draining the oil has spring (2) between nut and the packing ring (8).
