Abstract
The utility model relates to an ejector rod type water-cooled engine with a balancing shaft. The engine comprises a left crankcase and a right crankcase, a crankshaft and a balancing shaft positioned on the left and right crankcase, an oil pump positioned on the right crankcase and a water pump positioned on the right crankcase cover. The crankshaft is equipped with a balanced drive gear, the balancing shaft is equipped with a balanced driven gear, the balanced drive gear is engaged to the balanced driven gear, and the oil pump shaft is equipped with an oil pump gear for engaging to the balanced driven gear on the balancing shaft. The axis of the water pump shaft is in the same line of the axis of the balancing shaft and ends of the shafts are connected. When the engine operates at the idle speed, the cooling water pump still works normally, and the cooling water circulates well in the engine, so the engine obtains reliable cooling. Meanwhile, the utility model omits the chain wheel and chain on the original crankshaft and oil pump shaft, reduces the parts and components of the engine, and so reduces the manufacturing cost of the engine to a certain extent.
Description
Technical field
The utility model relates to a kind of water cooled engine of post rod type band trunnion shaft.
Technical background
In the water cooled engine of motorcycle post rod type band trunnion shaft, the other trunnion shaft that is equipped with of its bent axle, the balance driving gear engagement of installing on one balance driven gear and the bent axle is installed on it, make bent axle drive the trunnion shaft rotation, to eliminate the single order vibrations of motor by balance driving gear and the balance driven gear that is meshed.Cover at right crankcase cooling waterpump is installed, make the cooling water circulation with cooled engine.Oil pump is installed on right crankcase, sprocket wheel is housed respectively on machine oil pump shaft and the bent axle, bent axle rotates by sprocket chain band engine oil pump shaft.Machine oil pump shaft and water pump spindle are located along the same line, and its axle head links to each other, and the moving water pump spindle of machine oil pump shaft rotating band is rotated.The motor of this kind structure is when motor is in idling mode, because machine oil pump shaft rotating speed is lower, and make that the rotating speed of water pump spindle is low, because what the cooling waterpump of motor adopted is single suction low pressure centrifugal pump, when the water pump spindle rotating speed is low, the water pump cisco unity malfunction makes cooling water carry out normal circulation in the cooling water passage of motor, easily causes engine cooling bad and influence the service behaviour of motor; And the sprocket wheel chain is installed on bent axle and machine oil pump shaft, has been increased the component of motor, increased the manufacture cost of motor to a certain extent.
The model utility content
Technical problem to be solved in the utility model provides a kind of water cooled engine of post rod type band trunnion shaft, makes motor also can obtain good cooling when idling mode, simplifies the internal structure of motor simultaneously.
The water cooled engine of post rod type band trunnion shaft described in the utility model, comprise left and right crankcases, be installed in bent axle and trunnion shaft on the left and right crankcases, and be installed in the oil pump on the right crankcase and be installed in the water pump that right crankcase covers, the balance driving gear is installed on the bent axle, the balance driven gear is installed on the trunnion shaft, the engagement of balance driving gear and balance driven gear is meshed with balance driven gear on the trunnion shaft in that oil pump gear is installed on the machine oil pump shaft; Water pump spindle axis and trunnion shaft axis are located along the same line, and its axle head is continuous, make trunnion shaft drive water pump spindle and rotate.
Bent axle drives the trunnion shaft rotation by balance driving gear mounted thereto and the balance driven gear that is installed on the trunnion shaft, and trunnion shaft drives the water pump spindle rotation that is connected with its axle head, simultaneously, the balance driven gear on the trunnion shaft by with the machine oil pump shaft of its engagement on oil pump gear drive the machine oil pump shaft and rotate.
The water cooled engine of post rod type band trunnion shaft described in the utility model, because its cooling waterpump is directly driven by trunnion shaft, and trunnion shaft rotating ratio machine oil pump shaft when engine idle is fast, so when motor is in idling mode, cooling waterpump still can proper functioning, thereby guarantee that cooling water can carry out good circulation in motor, motor is cooled off reliably; Simultaneously,, saved sprocket wheel and chain on former bent axle and the machine oil pump shaft, reduced the component of motor, reduced the manufacture cost of motor to a certain extent because the machine oil pump shaft is driven by the balance driven tooth on the trunnion shaft.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is described in further detail.
Fig. 1 is the arrangement schematic representation of bent axle, trunnion shaft and water pump spindle of the water cooled engine of post rod type band trunnion shaft described in the utility model;
Fig. 2 is that the position of the utility model balance driving tooth, balance driven tooth and oil pump tooth concerns schematic representation.
Embodiment
As shown in Figure 1 and Figure 2, the water cooled engine of this post rod type band trunnion shaft comprises left and right crankcases 8,11, is installed in bent axle 10 and trunnion shaft 9 on the left and right crankcases 8,11, and be installed in the oil pump 6 on the right crankcase 11 and be installed in the water pump 3 that right crankcase covers, balance driving gear 1 is installed on the bent axle 10, balance driven gear 4 is installed on the trunnion shaft 9, balance driving gear 1 and 4 engagements of balance driven gear are meshed with balance driven gear 4 on the trunnion shaft 9 in that oil pump gear 5 is installed on the machine oil pump shaft 7; Water pump spindle 2 axis and trunnion shaft 9 axis are located along the same line, and its axle head is continuous, make trunnion shaft 9 drive water pump spindles 2 and rotate.
Bent axle 10 rotates and drives balance driving gear mounted thereto 1 rotation, balance driving gear 1 drives and the balance driven gear 4 that is installed on the trunnion shaft 9 of its engagement rotates, rotate thereby drive trunnion shaft 9, trunnion shaft 9 drives the water pump spindle 2 that is connected with its axle head and rotates; Simultaneously, the balance driven tooth 4 on the trunnion shaft 9 drives and the oil pump gear 5 that is installed on the machine oil pump shaft 7 of its engagement rotates, and rotates thereby drive machine oil pump shaft 7.
