Abstract
The utility model relates to an engine case of motorcycle. The engine case has a withdrawable secondary filter element. The engine case consists a left case (1) and a right case (2). The two cases are fixed together, and both of them are set with a lubricating oil pipe. The left case is set with two independent cavities, including the oil sump tank cavity and the secondary filter cavity (1b), on its front bottom. A secondary filter element is set in the secondary filter cavity (1b), and an end cover is set out the secondary filter cavity (1b). There is oil pipe, which connects with lubricating oil pump, on the right case (2). The oil pump connects with one side of the secondary filter cavity (1b) via the oil pipe on the left case (1). And the oil pipe on the left case (1) is also connecting with the secondary filter cavity (1b), and with the lubricating oil pipe on the right case (2) as well. Meanwhile, the lubricating oil pipe on the right case (2) connects with the oil pipe on the right case cover (11). The oil pipe on the right case cover (11) connects with the oil pipe in the crankshaft (4) within the engine case. Moreover, the oil pipe in the crankshaft (4) connects with the oil pipe in crankpin (5).
Description
Technical field
The utility model belongs to the motorcycle engine field, relates generally to a kind of motorcycle engine housing with replaceable secondary filter filter core.
Background technique
The pedal motorcycle single-cylinder engine casing of 50ml～150ml discharge capacity that present domestic typing is produced has all adopted engine case body structure as shown in Figure 1.Bent axle drives oil pump shaft and rotates when adopting the engine operation of this casing, after lubricant oil comes out from oil pump, send in the centrifugal filtration cavity that constitutes by bent axle 4 and side plate 3 by the oil leab 2a on the right case 2, lubricant oil after centrifugal filtration is in action of centrifugal force, and the oil duct that flows into crank pin 5 lubricates crank pin, bearing and connecting rod 6 hole surfaces.Lubricant oil relies on crankshaft rotating to drive its rotation, under the centrifugal action that the lubricant oil sole mass produces, makes it finish lubricated by crank pin 5 oil ducts inflow connecting rod and bearing.Because this filtrating equipment and crank one belong to disposable non-exchange formula, use filtering function to reduce for a long time, influence the efficient and the life-span of motor, be not easy to the maintenance, repair of motor, need dismantle casing during replacing, effort, time-consuming.
Summary of the invention
The purpose of this utility model provides a kind of motorcycle engine housing of being convenient to the replaceable secondary filter filter core of having of maintenance, repair.
The purpose of this utility model can adopt following technological scheme to realize: it comprises left box body and right case, a left side, right case is fixedly connected, on a left side, right case is provided with oil leab, the oil sump position of the preceding bottom of left box body has oil sump chamber and two separate chamber of secondary filter chamber, the secondary filter filter core is set in the secondary filter chamber, the outer installment of secondary filter chamber has end cap, be communicated with oil duct on the right case that the lubricant oil oil pump is connected oil duct and secondary filter chamber one end by a side on the left box body, secondary filter chamber top left box body is provided with the oil duct that communicates with the secondary filter chamber, it is connected with oil leab on the right case, oil leab on the right case is connected with oil duct on the right case lid, oil duct on the right case lid and the oil duct in the bent axle in the engine housing are communicated with, and the oil duct in the bent axle is communicated with the oil duct of crank pin.
By last structure as can be seen, the utility model has realized secondary filter is placed on the purpose of box house, has dwindled the boundary dimension of motor simultaneously, is convenient to the installation of engine accessory power rating.The essence of having finished lubricant oil by the secondary filter filter core filters journey.The utility model has utilized the chamber of oil sump, secondary filter filter core dismounting and change in the secondary filter chamber can be made it easy to maintenance, repair by the end cap on the left box body.The utility model has improved engine lubrication system, has improved the reliability of component work.
