All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The power system of the present invention is described below with reference to fig. 1 to 4.

The power system provided by the utility model comprises an engine 100, an oil pump 200 and a gearbox 300, wherein the engine is used as a core power source, one end of the engine is provided with a first output shaft, and the other end of the engine is provided with a second output shaft. The first output shaft is in direct drive connection with the oil pump 200 for providing hydraulic oil to the pumping system. The first output shaft is directly connected with the oil pump 200 in a transmission mode, intermediate power transmission mechanisms such as a gearbox, a universal joint, a transmission shaft and a transfer case can be omitted, and energy loss in the transmission process is reduced. The second output shaft is connected with the gearbox 300 and used for outputting power to the chassis for the chassis to walk.

In the prior art, the first output shaft of the engine 100 is used for connecting with the fan 604 of the heat sink 600, and in the present application, the heat sink 600 is shifted to other positions for connecting with the oil pump 200.

In an embodiment of the present invention, the oil pump 200 is connected to the first output shaft through the first clutch coupling 400, and the first clutch coupling 400 can connect and disconnect the first output shaft to and from the oil pump 200.

In one embodiment of the present invention, a second clutch coupling 500 is disposed between the transmission case 300 and the second output shaft, or may be a clutch, for connecting and disconnecting the second output shaft to and from the transmission case 300.

In one embodiment of the present invention, the power system provided by the present invention further comprises a heat sink 600. The heat sink 600 in the prior art is only used for dissipating heat of the engine 100, and only includes an intercooling system 601 and a water cooling system 602, which are connected to the first output shaft of the present application. The heat sink 600 of the present invention is used to dissipate heat from the engine 100 and the hydraulic oil.

Since the position of the first output shaft is occupied by the oil pump 200, the heat sink 600 in the present invention may be disposed on the chassis.

The heat dissipation device 600 of the present invention includes an engine heat dissipation body, a hydraulic oil heat dissipation body, and a fan 604, and dissipates heat to the engine 100 and the hydraulic oil in an air cooling manner.

The engine radiator comprises an intercooling system 601 and a water cooling system 602.

The function of the intercooling system 601 is to reduce the intake air temperature of the engine 100. Typically made of an aluminum alloy material. The conventional intercooling system 601 may be classified into an air cooling type and a water cooling type according to a cooling medium. The intercooling system 601 provided by the utility model adopts an air cooling type.

The intercooling system 601 is used for cooling the pressurized air discharged from the supercharger, the pressure of the air is increased and the temperature of the air is increased after the air passes through the supercharger, and the temperature of the pressurized air can be reduced through cooling of the intercooling system 601, so that the air density is improved, the charging efficiency is improved, and the purposes of improving the power of a diesel engine and reducing emission are achieved.

When compressed at a high rate, the air may generate a high amount of heat, thereby reducing the expansion density of the air and also causing damage to the engine 100 due to excessive temperatures. To achieve higher volumetric efficiency, it is necessary to cool the hot air prior to injection into the cylinder. The principle of the radiator is similar to that of a water tank radiator, high-temperature and high-pressure air is dispersed into a plurality of fine pipelines, and normal-temperature air flows through the pipelines at high speed, so that the aim of cooling is fulfilled, and the temperature of the air can be reduced from 150 ℃ to about 50 ℃. Since this heat dissipation system is located between the engine 100 and the turbocharger, it is also referred to as a central cooling system, abbreviated as intercooling system 601.

The water cooling system 602 functions to reduce the temperature of the coolant of the engine 100, and thus, the temperature of the engine 100. The water cooling system 602 is composed of a water inlet chamber, a water outlet chamber, and a radiator core. The coolant of engine 100 flows through the radiator core, and the air passes through the outside of the radiator core. The hot coolant dissipates heat to the air to become cold, and the cold air absorbs heat dissipated by the coolant to become warm.

The hydraulic oil radiator comprises an oil cooling system 603, and the oil cooling system 603 is used for engineering machinery using hydraulic oil as a force transmission medium, such as a concrete delivery pump. The oil cooling system 603 is mainly used for a loop of the oil pump 200. During operation, high-temperature oil flows through the oil cooling system 603, and performs efficient heat exchange with cold air forcibly flowing in the heat exchanger, so that the oil temperature is reduced to the working temperature to ensure that the oil pump 200 can continuously operate normally, and the operation can be smoothly performed.

In an embodiment of the present invention, since the first output shaft is occupied by the oil pump 200, the heat sink 600 needs to be driven by another power device, the power device in this embodiment is the hydraulic motor 605, the hydraulic motor 605 is connected to the oil pump 200, the oil pump 200 drives the hydraulic motor 605 to operate, and further drives the fan 604 of the heat sink 600 to operate, so as to provide cooling air for the inter-cooling system 601, the water cooling system 602, and the oil cooling system 603.

In an embodiment of the present invention, the oil pump 200 may use a gear pump or a vane pump.

The utility model also provides a chassis, which comprises a chassis main body and the power system, wherein the power system is arranged on the chassis main body. The chassis has the same advantages as the power system described above because of the power system described above.

The utility model also provides a pumping machine, which comprises the chassis and the pumping system, for example, the pumping machine can be a concrete pump truck, and comprises the pumping system and the chassis.

The chassis is used for driving the whole concrete pump truck to run, and a gearbox 300 in a power system on the chassis is in transmission connection with a running system of the chassis and used for driving the concrete pump truck to run. An oil pump 200 in the power system is connected to the pumping system for providing power to the concrete.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
