[0034] The embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0035] like Figure 1 and Figure 2 As shown, the power system 100 of this utility model embodiment includes an engine 1, a gearbox 2, an intake device 3, and an exhaust gas treatment box 4. The engine 1 and the gearbox 2 are arranged sequentially along the length direction of the power system 100. The engine 1 is provided with a first output end 11 that is in transmission cooperation with the gearbox 2 on the side near the gearbox 2, and the extension direction of the output shaft of the first output end 11 is parallel to the length direction of the power system 100. The intake device 3 and the exhaust gas treatment box 4 are located on the same side of the engine 1 and are arranged at intervals along the length direction of the power system 100.
[0036] Specifically, the length direction of the power system 100 is the front-to-back direction, which is also the front-to-back direction of the entire transport vehicle and frame 200. The width direction of the power system 100 is the left-to-right direction. The output shaft of the first output end 11 of the engine 1 and the input shaft of the gearbox 2 share the same shaft, or the output shaft of the first output end 11 of the engine 1 and the input shaft of the gearbox 2 are connected by a coupling. The power output by the engine 1 can be directly transmitted to the gearbox 2, avoiding the need to set other transmission equipment between the engine 1 and the gearbox 2, and reducing the loss in the power transmission process. Setting the intake device 3 and the exhaust gas treatment box 4 on the same side of the engine 1 can reduce the size of the engine 1, the intake device 3 and the exhaust gas treatment box 4 in the width direction of the power system 100, which is convenient to avoid affecting the overall center of gravity of the mixer transport vehicle when the power system 100 is installed.
[0037] The power system 100 of this utility model embodiment optimizes the layout position, simplifies the power transmission path of the power system 100, shortens the space occupied by the power system 100 during layout, thereby eliminating the influence of the power system 100 on the width direction of the mixer truck, and ensuring that the mixer truck has good passability when driving in the roadway.
[0038] In some embodiments, such as Figure 1 and Figure 2 As shown, it includes a heat dissipation device 5, which is located on the side of the engine 1 away from the gearbox 2. The engine 1 has a second output end 12 corresponding to the heat dissipation device 5, and the heat dissipation device 5 is driven to the second output end 12.
[0039] The cooling device 5 is placed on the side of the engine 1 away from the gearbox 2 to avoid increasing the width of the power system 100 by installing the cooling device 5. At the same time, it is convenient to connect the cooling device 5 to the second output terminal 12, so that the engine 1 can deliver power to the cooling device 5.
[0040] In some embodiments, the heat dissipation device 5 includes a heat dissipation fan, the input shaft of which is connected to the output shaft of the second output terminal 12, and the axis of the input shaft of the heat dissipation fan is parallel to or coincides with the axis of the output shaft of the second output terminal 12.
[0041] Specifically, the input shaft of the cooling fan and the output shaft of the second output terminal 12 of the engine 1 are the same shaft, or the input shaft of the cooling fan and the output shaft of the second output terminal 12 of the engine 1 are connected by a coupling. This ensures the operation of the cooling fan when the engine 1 is rotating, avoids setting other transmission devices between the cooling fan and the engine 1, reduces the overall space occupied by the power system 100, and facilitates the installation of the power system 100.
[0042] In some embodiments, such as Figure 1 As shown, the side of the air intake device 3 closest to the engine 1 and the side of the exhaust gas treatment box 4 furthest from the gearbox 2 do not exceed the side of the heat dissipation device 5 away from the gearbox 2. That is, when the length of the heat dissipation device 5 and the engine 1 in the longitudinal direction is fixed, the position of the air intake device 3 and the exhaust gas treatment box 4 in the longitudinal direction is restricted to reduce the size of the power system 100 in the longitudinal direction, so as to reduce the length of the entire mixer truck.
[0043] In some embodiments, the top surface of the exhaust gas treatment box 4 does not exceed the top surface of the air intake device 3. By limiting the height of the exhaust gas treatment box 4, the spatial position of the air intake device 3 and the exhaust gas treatment box 4 during installation is ensured, further reducing the space occupied by the power system 100 during overall installation.
[0044] In some embodiments, such as Figure 1 and Figure 2 As shown, a transmission rod 21 is provided on the side of the gearbox 2 away from the engine 1. The other end of the transmission rod 21 is provided with a transfer case 6. A first drive rod 61 and a second drive rod 62 are provided on the transfer case 6. The other end of the first drive rod 61 is connected to the front drive axle, and the other end of the second drive rod 62 is connected to the rear drive axle 63.
[0045] When engine 1 is operating, the speed output of engine 1 is adjusted by gearbox 2, and then the transmission rod 21 connected to gearbox 2 transmits the power to transfer case 6. The power is further transmitted to front drive axle and rear drive axle 63 by first drive rod 61 and second drive rod 62 on transfer case 6, so that the tires on front drive axle and rear drive axle 63 are all drive wheels.
[0046] In some embodiments, such as Figure 1 As shown, two rear drive wheels 64 are respectively provided at both ends of the rear drive axle 63, and the engine 1, intake device 3 and exhaust gas treatment box 4 are all located between the outer end faces of the two rear drive wheels 64.
[0047] When installing the power system 100, the outer sides of the two rear drive wheels 64 determine the end face positions of the frame 200 and the body of the mixer truck in the left and right directions. By placing the engine 1, the air intake device 3 and the exhaust gas treatment box 4 between the outer end faces of the two rear drive wheels 64, it is possible to prevent the engine 1, the air intake device 3 or the exhaust gas treatment box 4 from extending out of the frame 200 and the body, thus ensuring the overall width dimension of the mixer truck.
[0048] In some embodiments, such as Figure 1As shown, there is a set distance between the output shaft of the first output end 11 and the second drive rod 62, and the air intake device 3 and the exhaust gas treatment box 4 are located on the side of the second drive rod 62 away from the engine 1.
[0049] By limiting the position of the first output end 11, the problem of the center of gravity of the power system 100 shifting in the left and right directions, which may be caused by the air intake device 3 and the exhaust gas treatment box 4 being located on the same side of the engine 1, is solved, thus ensuring the stability of the center of gravity and the operational reliability of the power system 100 and the mixer truck as a whole.
[0050] In some embodiments, the gearbox 2 is located on the side of the rear drive axle 63 opposite to the front drive axle, ensuring that there is a set distance between the front drive axle and the rear drive axle 63, so as to reserve space for the installation of the mixing tank 300 and avoid interference between the power system 100 and the mixing tank 300 during installation.
[0051] The following describes a concrete mixer truck according to an embodiment of the present invention.
[0052] like Figure 3 and Figure 4 As shown, the concrete mixer truck of this utility model includes a frame 200, a mixing tank 300 and a power system 100 of any of the above embodiments. The mixing tank 300 and the power system 100 are mounted on the frame 200. The engine 1 is provided with a third output end, which is connected to the mixing tank 300 for driving the mixing tank 300 to rotate.
[0053] The concrete mixer truck of this utility model simplifies the power delivery path and reduces the impact of the power system 100 on the size of the concrete mixer truck in the width direction by setting the power system 100, while ensuring good passability of the concrete mixer truck when traveling in the tunnel.
[0054] In some embodiments, such as Figure 3 and Figure 4 As shown, it includes a cab 400, which is located at the front of the frame 200. The engine 1 and the gearbox 2 are located at the rear of the frame 200. By setting the cab 400 and the engine 1 and gearbox 2 at the front and rear ends of the frame 200, it is convenient to adjust the overall center of gravity of the mixer truck and ensure the stability of the mixer truck during travel.
