Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.Should be understood that, embodiment described herein, only for instruction and explanation of the utility model, is not limited to the utility model.
The utility model provides a kind of engine assembly, as in Fig. 1, include air compressor 1 and fuel pump 2 in this engine assembly, wherein, the pump shaft 21 of fuel pump 2 is connected to the bent axle 11 of air compressor 1, to drive the pump shaft 21 of fuel pump 2 to rotate by the bent axle 11 of air compressor 1.
The engine assembly that the utility model provides, be connected with the bent axle 11 of air compressor 1 by the pump shaft 21 of fuel pump 2, rotation is driven by the bent axle 11 of air compressor 1, like this, it is fixing on the engine that fuel pump 2 and air compressor 1 are connected to form an entirety, this technological scheme is different from the technological scheme of prior art intermediate fuel oil pump 2 by timing gear (or sprocket wheel) system drive of motor, compared to existing technology, in the engine assembly that the utility model provides, the layout of air compressor 1 and fuel pump 2 makes the structure of engine assembly compacter, occupy little space, be conducive to arrangement.
In the embodiment that the utility model provides, as shown in Figure 1-Figure 3, pump shaft 21 end of fuel pump 2 is provided with key 211, bent axle 11 end face of air compressor 1 is provided with the keyway 111 matched with key 211, wherein, key 211 is the projection of approximate hydraulic steering gear adopting cross piece shape, the shape of keyway 111 and the form fit of key 211, key 211 can be plugged in keyway 111, realize the connection of pump shaft 21 and bent axle 11, air compressor 1 and fuel pump 2 are fixed on the engine simultaneously, like this, fuel pump 2 pump shaft 21 is driven to rotate when the bent axle 11 of air compressor 1 rotates.
Can respond fast under the driving of air compressor 1 for making fuel pump 2, higher to the requirement on machining accuracy of key 211 and keyway 111, key 211 is less with the matching gap of keyway 111, thus key 211 and keyway 111 can fasteningly be plugged in together, like this, air compressor 1 is when starting, and the pump shaft 21 of fuel pump 2 can start fast with bent axle 11, and the impulsive load that fuel pump 2 is operationally subject to is little.
But because key 211 is little with the matching gap of keyway 111, and key 211 and keyway 111 can produce certain coaxiality error in manufacturing process, and therefore both may exist the phenomenon that assembling is difficult or cannot assemble when assembling.For addressing this problem, in present embodiment, as shown in Figure 2, pump shaft 21 end of fuel pump 2 is provided with bar blocks 212, the length direction of this bar blocks 212 is perpendicular to the axis of pump shaft 21, key 211 is set in this bar blocks 212, gap is provided with between key 211 and two ends of bar blocks 211, in assembly process, key 211 slightly can slide back and forth along the length direction of bar blocks 212 (as the direction of arrow in figure), to compensate the coaxiality error produced in manufacture process, realize the assembling of key 211 and keyway 111.
In present embodiment, as shown in Figure 5, the bottom of air compressor 1 is provided with oil sump 12, under normal circumstances, oil sump 12 is arranged at the bottom symmetrical of bent axle 11, but, oil sump 12 can produce with the structure on motor 1 when air compressor 1 is assemblied on motor 3 interferes, air compressor 1 is assemblied in structural representation on motor 3 as shown in Figure 4, for avoiding interfering, oil sump (12) below bent axle 11 away from the side of motor 3, namely oil sump 12 is to the side skew certain distance away from motor 1, oil sump 12 is relative to bent axle 11 eccentric setting in other words.As in Fig. 5, the perpendicular distance of the both sides of the edge on oil sump 12 is longitudinal and the vertical center line of bent axle 11 is respectively L1 and L2, L1 is greater than L2, oil sump 12 offsets to the direction away from motor 3 in the bottom of bent axle 11, then oil sump 12 can not produce with the structure on motor 3 and interfere, and does not affect the installation of air compressor 1 on motor 3.
The utility model is another embodiment also provide a kind of vehicle, and this vehicle includes engine assembly described in the utility model.
Below preferred implementation of the present utility model is described by reference to the accompanying drawings in detail; but; the utility model is not limited to the detail in above-mentioned mode of execution; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
It should be noted that in addition, each concrete technical characteristics described in above-mentioned embodiment, in reconcilable situation, can be combined by any suitable mode, in order to avoid unnecessary repetition, the utility model illustrates no longer separately to various possible compound mode.
In addition, also can carry out combination in any between various different mode of execution of the present utility model, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
