By mounting the transmission assembly and the engine crank shaft in the same box body, an engine can be directly connected with the transmission assembly via the belt pulley, so that a middle transmission device in the engine and a transmission can be omitted, power speed can be changed via the transmission assembly before inputting power, and the engine achieves the effect of automatic transmission. Therefore, failure rate of motor vehicles is reduced, energy utilization ratio is increased, energy is saved, noise pollution is decreased and environmental protection is realized.
Description
Technical field
The utility model relates to a kind of motor from speed change gear.
Background technique
The motor and the speed changer of ordinary motor vehicle are two independently members, at motor vehicle interiors, the two is independent, be installed separately in two casings, be connected by centre driving components such as gear, connecting rod, chain, clutches between motor and the speed changer, the power that motor produces is not directly passed to speed changer, but passes to speed changer indirectly by driving component in the middle of baroque.
Though motor and speed changer are separated from each other, independent structure of installing is convenient to maintenance and change component, but because the existence of middle driving component, motor vehicle can have following shortcomings: 1. motor vehicle need bigger installing space, to be used for that middle driving component is installed, it is smaller and more exquisite to make that motor vehicle are difficult to design; 2. driving component in the middle of many then means to have more numerous parts, out of order probability when having strengthened the motor vehicle operation; 3. owing to there is middle driving component, then the path of power transmission is longer, and motor vehicle can extraneoas loss fall more energy when operation; 4. owing to there is middle driving component, motor vehicle can produce more noise pollution when operation.
The model utility content
Technical problem to be solved in the utility model provides a kind of motor from speed change gear.
The technical scheme in the invention for solving the technical problem is: this motor is equipped with transmission assembly and engine crankshaft from speed change gear in its casing, the engine power output terminal of described engine crankshaft stretches out casing, the speed changer power intake of described transmission assembly stretches out casing, connects by belt wheel between the engine power output terminal of engine crankshaft and the speed changer power intake of transmission assembly.
Compared with prior art, the beneficial effects of the utility model are: 1. the utility model is installed in motor and speed changer in the middle of the same casing, make between motor and the transmission assembly and directly be connected to become possibility by belt wheel, driving component in the middle of being saved makes motor and speed changer be integral structure; Because motor directly is connected by belt wheel with transmission assembly, power is exported by speed changer clutch end 122, and thus, power has just carried out speed change by transmission assembly 12 before output, makes motor reach effect from speed change.2 because the utility model has saved middle driving component with respect to prior art, thereby makes motor vehicle only need to be connected with transmission assembly, reduces the out of order probability of motor vehicle greatly.3. saved middle driving component owing to the utility model with respect to prior art, thereby saved installing space, it is smaller and more exquisite to make that motor vehicle can design.4. because the utility model adopts motor and speed changer to be installed in the integral structure of same casing, save middle driving component, made that the transfer route of power is shorter, improved energy utilization ratio, saved the energy, more environmental protection.5. because the utility model has adopted motor and speed changer to be installed in the integral structure of same casing, save middle driving component, reduced noise pollution, protected environment.
Description of drawings
Fig. 1 is the structural representation of the utility model motor from speed change gear.
Among the figure, 1. first engine crankshaft bearing, 2. engine crankshaft, 3. crank, 4. casing, 5. second engine crankshaft bearing, 6. connection belt, 7. driving pulley flat key, 8. driving pulley locking nut, 9. driving pulley, 10. driven pulley, 11. driven pulley flat keys, 12. transmission assembly, 13. driven pulley locking nuts, 21. engine power output terminals, 121. the speed changer power intake, 122. speed changer clutch ends.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
As shown in Figure 1, the utility model is installed in transmission assembly 12 and engine crankshaft 2 in the same casing 4.Wherein, be connected to form by bearing between each of transmission assembly 12 and the casing 4 and be slidingly matched.Be separately installed with first engine crankshaft bearing 1 and second engine crankshaft bearing 5 on two relative inwalls of casing 4, engine crankshaft 2 forms with casing 4 by first engine crankshaft bearing 1 and second engine crankshaft bearing 5 and is slidingly matched.The engine power output terminal 21 of engine crankshaft 2 and the speed changer power intake 121 of transmission assembly 12 all stretch out casing 4, and, connect by belt wheel between the engine power output terminal 21 of engine crankshaft 2 and the speed changer power intake 121 of transmission assembly 12: promptly engine power output terminal 21 forms a fixed connection by driving pulley flat key 7 and driving pulley 9, and driving pulley locking nut 8 is fastened on driving pulley 9 on the engine power output terminal 21 of engine crankshaft 2; Driven pulley 10 is fixedlyed connected with the speed changer power intake 121 of transmission assembly 12 by driven pulley flat key 11, driven pulley locking nut 13 is fastened on movable belt pulley 10 on the speed changer power intake 121, thereby driven pulley 10 and transmission assembly 12 integral body are formed a fixed connection; 10 of driving pulley 9 and driven pulleys are connected by belt 6.
During the utility model work, motor flows to bent axle 2 by crank 3 with power, bent axle 2 flows to driving pulley 9 by engine power output terminal 21 with power, driving pulley 9 flows to driven pulley 10 by connecting belt 6 with power, driven pulley 10 flows to speed changer power intake 121 with power, after transmission assembly 12 speed changes, the utility model finally outputs power by speed changer clutch end 122.Because motor of the present utility model and transmission assembly 12 are installed in the same casing, motor directly is connected by belt wheel with transmission assembly 12, power is by 122 outputs of speed changer clutch end, thus, power is before output, just carried out speed change, made motor reach effect from speed change by transmission assembly 12.
To sum up, in the prior art, motor is directly to be connected with middle driving component by belt wheel, motor vehicle then are connected with transmission assembly 12 with middle driving component simultaneously, the power transmission path of this Placement is long, and middle driving component damages easily, causes motor vehicle to be out of order easily.And the utility model design is unique, by motor and transmission assembly 12 are installed in the same casing, make between motor and the transmission assembly 12 and directly be connected to become possibility by belt wheel, driving component in the middle of being saved thus, thereby make motor vehicle only need to be connected, reduce the out of order probability of motor vehicle greatly with transmission assembly; And, because motor of the present utility model directly flows to power transmission assembly 12, make power transmission line short, improved energy utilization ratio thus, saved the energy, promote environmental protection.In addition, in the prior art, motor and speed changer are the independent components that is installed separately in two casings, and installing space is huge, can't be applicable to small-sized motor vehicle; The utility model motor is then saved installing space greatly from speed change gear, applicable to the smaller and more exquisite motor vehicle of design.Moreover, the utility model motor is the structure of a sealing from speed change gear on the whole, has reduced noise pollution, has protected environment.
