Abstract
The utility model is to make the oil circuit C on the side of the crankshaft part(right half part) for the prior cylinder body upwards extend a section of extending oil circuit, and an oil hole position D is positioned on the place in the crankshaft cavity on the back corresponding to the extending oil circuit, and the oil hole position D is provided with an oil hole E. The oil hole E makes the extending oil circuit and the crankshaft cavity communicated, and the supplying channel for the lubricating oil is: oil pump-oil circuit C-oil hole E-crankshaft cavity. The utility model is of a scientific design for the oil circuit, easy manufacturing and smooth oiling, which can ensure that the lubrication oil supplies to the part needing to be lubricated for the crankshaft, and the service life of the engine cylinder is prolonged.
Description
The utility model relates to motorcycle engine, especially the motorcycle engine cylinder.
The oil feed line design of existing motorcycle engine cylinder lubricating system is unreasonable, its structure as shown in Figure 3, on cylinder body crank portion limit, be provided with lubricant pipe C, the upper end of oil pipe C is provided with oilhole B and F, wherein oilhole B is the passage that lubricant oil enters the back crankshaft cavity, be provided with corresponding grease channel and connect oilhole B and crankshaft cavity on bearing, the service duct of its lubricant oil is: oil pump (not shown) → oil pipe C → oilhole B → bearing → crankshaft cavity.The major defect of this lubricant oil service duct is: not smooth during lubricant oil process bearing, occur easily stopping up, and can not lubricate the cylinder bent axle when serious, motor is broken down, the working life of shortening cylinder.
The purpose of this utility model is that existing Cylinder of motorcycle lubricant oil supply pipeline is transformed, and makes its unimpeded difficult obstruction, guarantees the lubricated of engine crankshaft, prolongs the working life of cylinder.
The purpose of this utility model realizes by following design:
Oil circuit C on existing cylinder body crank portion (right-hand part) limit is extended upward one section extend oil circuit, the corresponding oil circuit place of extending is provided with the oilhole position in the crankshaft cavity at its back side, the place is drilled with oilhole in the oilhole position, oilhole will extend oil circuit and crankshaft cavity is communicated with, and the supply passage of its lubricant oil is: oil pump → oil circuit C → extension oil circuit → oilhole → crankshaft cavity.
The utility model oil circuit design science is easy to make, and the fuel feeding smoothness can guarantee the position that lubricant oil supply bent axle need lubricate during use, prolong the working life of cylinder.
Example below in conjunction with accompanying drawing is further described the utility model:
Fig. 1 is a configuration diagram of the present utility model;
Fig. 2 is a back side of the present utility model diagrammatic sketch;
Fig. 3 is the bent axle right-hand part comparison diagram of existing Cylinder of motorcycle.
The utility model is to transform to form on the basis of the lubricant oil supply oil circuit of existing Cylinder of motorcycle bent axle right-hand part.As depicted in figs. 1 and 2, oil circuit C on the crank portion limit is extended upward one section extend oil circuit A, the corresponding oil circuit A place of extending is provided with oilhole position D in the crankshaft cavity at its back side, be drilled with oilhole E (E arrow indication is formed by straight tube+transverse tube) at D place, oilhole position, oilhole E will extend oil circuit A and crankshaft cavity is communicated with, and the supply passage of its lubricant oil is: oil pump → oil circuit C → extension oil circuit A → oilhole E → crankshaft cavity.
Claims (1)
1, a kind of Cylinder of motorcycle crank portion, it is characterized in that: the oil circuit (C) on the cylinder body crank portion limit is extended upward one section extend oil circuit (A), the corresponding oil circuit (A) that extends locates to be provided with oilhole position (D) in the crankshaft cavity at its back side, locate to be drilled with oilhole (E) at oilhole position (D), oilhole (E) will extend oil circuit (A) and crankshaft cavity is communicated with.
