Description

Technical Field

[0001] The invention relates to the field of mixer trucks, and in particular to a mixer truck and a driving modification method thereof. Background Art

[0002] Mixer trucks refer to concrete mixer trucks, which are special trucks used to transport concrete for construction. These trucks are usually equipped with energy recovery systems, onboard air conditioning and mixing tops, among which:

[0003] The mixing top is driven by an engine, which consumes a lot of fuel. When the mixer truck is parked on the construction site to perform mixing work or even parked to wait, the engine corresponding to the mixing tank cannot be turned off, and must run at a low and uniform speed to continuously output the power to drive the top to rotate, thus increasing fuel consumption. In response to the above problems, there is a method in the prior art to drive the top to rotate by a motor, so that the driving force for the rotation of the top is no longer dependent on the engine, thereby effectively reducing fuel consumption. However, when the traditional motor is connected to the original reduction box on the mixer truck, there are the following defects:

[0004] First, the traditional motor has a large deadweight and a long axial dimension. Therefore, when the traditional motor is connected to the original reducer on the mixer truck, the outer shell of the original reducer cannot withstand the bending moment and shear force caused by the deadweight of the motor, and is prone to cracking. If necessary, it needs to be redesigned or even replaced with a new reducer outer shell that matches the traditional motor, or a reduction integrated motor is used to completely replace the original reducer.

[0005] Second, even if the traditional motor has an additional support base to bear its own weight, there are still problems of vibration and movement when the upper part changes speed and rotates, and the impact of its own weight cannot be completely eliminated.

[0006] It can be seen that both of the above two technical solutions have the problems of high transformation cost, the need to redesign the motor support, and cumbersome debugging and installation.

[0007] The energy recovery system is to recover the kinetic energy of the vehicle during braking. However, due to the large body and front of the mixer truck, the use of traditional motors as generators will cause bending moment and shear force problems caused by their own weight. Similar to the mixer top, due to the long axial dimension of the drive generator and its heavy weight, the overall length is too long, which also causes the above defects and even shortens the service life.

[0008] The vehicle air conditioner is used to cool the cab on the mixer truck. Currently, all vehicle air conditioners are driven by engines and have high fuel consumption. Summary of the invention

[0009] In order to solve the above problems, the present invention provides a mixer truck and a drive modification method thereof which can effectively reduce fuel consumption, do not require additional support, effectively reduce costs, and are more energy-efficient.

[0028] As a preferred embodiment, the first original shell and the second original shell respectively have a supporting surface, the first original connection end is exposed on the supporting surface corresponding to the first original shell, and the supporting surfaces corresponding to the disc motor and the first original shell are roughly parallel and fit together; the second original connection end is exposed on the supporting surface corresponding to the second original shell, and the supporting surfaces corresponding to the disc motor and the second original shell are roughly parallel and fit together.

[0029] As a preferred embodiment, the disc motor is connected to the supporting surface via a connecting disc.

[0030] As a preferred embodiment, the mixer truck further includes an onboard air conditioner, and the onboard air conditioner includes:

[0049] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0050] like Figure 1As shown, a method for driving a mixer truck is provided, wherein the method is for modifying at least one driving device of the mixer truck, and comprises the following steps:

[0051] (a) removing the oil drive connected to the original connection ends 112a and 112b of the drive device;

[0052] (b) The disk motors 120a, 120b are directly connected to the original connection ends 112a, 112b of the driving device, and the disk motors 120a, 120b are supported by the original housings 111a, 111b of the driving device.

[0053] The drive transformation method is to remove the oil drive (such as a hydraulically driven engine, etc.) on the basis of the original drive equipment of the mixer truck, and replace it with the disc motor 120a, 120b, so as to effectively reduce the oil consumption. And the disc motor 120a, 120b can be directly connected with the original connection end 112a, 112b on the drive equipment, without adding additional structure, so that the transformation process is simpler and the transformation cost is reduced at the same time. In addition, the disc motor 120a, 120b has the characteristics of small axial size and lighter weight, and the disc motor 120a, 120b is directly supported on the original housing 111a, 111b. Compared with the traditional radial motor, the original housing 111a, 111b can bear the bending moment and shear force caused by the dead weight of the disc motor 120a, 120b, and will not deform or crack during long-term operation, so there is no need to add a new support structure, and avoid redesigning the original housing or the reduction integrated motor, effectively reducing the cost, extending the service life, and simplifying the installation and debugging process.

[0054] The following is a comparison table of radial motors and disc motors at the same power:

[0055]

[0056] Among them, the axial size and weight of the 120kW traditional radial motor are both larger than the 120kW disc motor. Figure 1 , the conventional radial motor is extended in the horizontal direction, and the center of gravity of the conventional radial motor is far away from the original housing 111a, 111b, which makes the motor bending moment larger. The disc motor has a smaller axial dimension, and relative to the conventional radial motor, it is only extended in the vertical direction, so that the center of gravity of the disc motor is closer to the original housing 111a, 111b, which makes the motor bending moment smaller, effectively improving the motor installation stability and reducing the load of the original housing 111a, 111b.

[0057] like Figure 1 , Figure 6 and Figure 7As shown, the driving device can be a stirring upper device 200, an energy recovery system 300 and an air conditioning system 400, etc., so as to change the oil drive to an electric drive to reduce oil consumption. In addition, a disc motor with a small axial size and light weight is adopted, so that no additional support is required, the cost is reduced, and the load of the original housing on the motor is reduced, thereby extending the service life.

[0058] like Figures 1 to 3 As shown, when the driving device is a stirring upper device 200, the stirring upper device 200 includes a first disc motor 120a, a reduction box and a stirring tank 210, the reduction box includes a first original housing 111a, and a first original connection end 112a exposed by the first original housing 111a, the first disc motor 120a is supported on the first original housing 111a, and connected to the first original connection end 112a, the method includes:

[0059] The first disc motor 120 a is supported by a reduction gear box of the stirring upper device 200 , so that the first disc motor 120 a can electrically drive the stirring tank 210 of the stirring upper device 200 .

[0060] The first original shell 111a serves as the shell of the reduction gearbox, the first original connecting end 112a serves as the input end of the reduction gearbox, and the output end of the reduction gearbox is connected to the stirring tank 210. Therefore, when the first disc motor 120a is connected to the first original connecting end 112a, the first disc motor 120a can electrically drive the stirring tank 210 to rotate.

[0061] The first disc motor 120a can be directly connected to the input end of the reducer and supported on the shell surface of the reducer. The mixing upper part 200 is fixed on the chassis 700 of the mixer truck and is located behind the cab 500, wherein the chassis 700 is horizontally arranged, and the mixing upper part 200 is inclined relative to the chassis 700, and of course, the two can also be roughly horizontal. The first disc motor 120a replaces the existing hydraulic engine to reduce fuel consumption, and can directly use the first original connection end 112a on the original drive device for connection without adding additional structures, making the modification process simpler and reducing the modification cost at the same time. Compared with the traditional radial motor, it also ensures the support capacity of the first original shell 111b.

[0062] like Figure 1 and Figure 6As shown, when the driving device is an energy recovery system 300, the energy recovery system 300 includes a second disc motor 120b, a power take-off and an engine 310, the power take-off includes a second original housing 111b, and a second original connection end 112b exposed by the second original housing 111b, the second disc motor 120b is a disc generator, the second disc motor 120b is supported on the second original housing 111b, and is connected to the second original connection end 112b, and the method includes:

[0063] The second disc motor 120 b is supported on a power take-off of the energy recovery system 300 , so that the second disc motor 120 b recovers energy from the engine 310 and charges the battery 440 .

[0064] The second original housing 111b serves as the housing of the power take-off, the second original connection end 112b may be the input end of the power take-off, and the output end of the power take-off is connected to the engine 310, so that the second disc motor 120b can be directly connected to the input end of the power take-off and supported on the housing surface of the power take-off. The second disc motor 120b serves as a generator, is located on the chassis 700, and is arranged behind the cab 500 to replace the hydraulic drive, which not only reduces fuel consumption, but also can directly use the second original connection end 112b on the original drive device for connection, and at the same time ensures the support capacity of the second original housing 111b for the second disc motor 120b, and prolongs the service life.

[0065] To further explain, the power take-off includes a power take-off body, an output shaft and a flange plate which are connected in sequence. At this time, the second disc motor 120b is fixed on the flange plate, that is, the flange plate is the second original housing 111b.

[0066] Continue to refer Figure 6 The energy recovery system further includes a universal joint 320, and the universal joint 320 is connected between the engine 310 and the power take-off.

[0067] like Figure 7 As shown, when the driving device is an air conditioning system 400, the method further includes:

[0068] The battery 440 is connected to the compressor 430 of the air conditioning system 400 to provide electric energy for the compressor 430 to operate.

[0069] The battery 440 provides power for the compressor 430 to work, further saving fuel consumption, and the mixing upper body 200 and the air conditioning system 400 are independently electrically driven, so when the air conditioning system 400 is used, the mixer truck can be turned off, which plays a role in energy saving and environmental protection. In addition, the battery 440 can also provide power for the first disc motor 120a, so it can be seen that the battery 440 can simultaneously power the air conditioning system 400 and the mixing upper body 200. Of course, the battery 440 can be powered by an external power supply.

[0070] The air conditioning system 400 may be an original onboard air conditioning system of the mixer truck, or may be an air conditioning system modified from the original onboard air conditioning system.

[0071] In summary, the mixer truck's mixing top 200, energy recovery system 300 and air conditioning system 400 can all be modified using the above-mentioned modification method, that is, on the basis of the original drive device, the disc motor is used to replace the oil drive, and the air conditioning system 400 can be electrically driven, which can save fuel consumption to a large extent. And because the disc motor has small axial dimensions and light weight, there is no need for additional support, which reduces costs, and reduces the load of the original housing on the motor, extending its service life. In addition, in the modification process of replacing the oil drive with the disc motor, the original connection end 112a of the original drive device can be directly used for connection, without the need to add additional structures, making the modification process simpler and reducing the modification cost at the same time, making it more suitable for the electric drive modification of existing fuel mixer trucks on the market.

[0072] like Figure 1 As shown, the original housing 111a, 111b has a supporting surface 1111, and the original connecting ends 112a, 112b are exposed by the supporting surface 1111, and the method includes:

[0073] The disk motors 120a and 120b are connected to the original connection ends 112a and 112b in a manner that they are substantially parallel to and in close contact with the support surface 1111.

[0074] The disk motors 120a and 120b have a small axial dimension, so the two end faces of the disk motors 120a and 120b are parallel and the distance defined between them is small. The end faces of the disk motors 120a and 120b facing the supporting surface 1111 are parallel to the supporting surface 1111, ensuring effective contact support between the two and improving the supporting capacity of the original housings 111a and 111b for the disk motors 120a and 120b.

[0075] like Figure 1 , Figure 4 and Figure 5 As shown, the step (b) further comprises the steps of:

[0076] (b1) providing a connection plate 130, wherein the connection plate 130 has a substantially parallel structural connection surface 131 and a motor connection surface 132;

[0077] (b2) connecting the primary housings 111a and 111b to the structural connection surface 131;

[0078] (b3) Fixing the disk motors 120a, 120b to the motor connection surface 132.

[0079] The connecting plate 130 serves to connect the disc motors 120a, 120b and the original housings 111a, 111b, and ensures a stable connection between the two, preventing the two from separating and affecting the reliability of the motor. The distance between the structural connection surface 131 and the motor connection surface 132 defines the axial dimension of the connecting plate 130. The connecting plate 130 and the disc motors 120a, 120b are both flat structures (i.e., small axial dimensions), thus effectively shortening the distance between the disc motors 120a, 120b and the supporting surface 1111, thereby preventing the motor bending moment from being too large and causing the original housings 111a, 111b to be unable to support the motor. In addition, the outer peripheries of the disk motors 120a, 120b and the connecting disk 130 can be flush to ensure the contact area between the two, so as to enhance the stability of the combination, and the outer periphery of the connecting disk 130 can be located within the area surrounded by the supporting surface 1111, that is, the end surfaces of the supporting surface 1111 facing the disk motors 120a, 120b are effectively contact-supported, thereby enhancing the supporting capacity of the original housing 111a, 111b for the disk motors 120a, 120b.

[0080] The connection plate 130 also has mounting holes 133a and 133b that penetrate the structural connection surface 131 and the motor connection surface 132 and are used for the fasteners to pass through. The fasteners can be bolts, etc., which can be divided into housing bolts for connecting the original housings 111a and 111b, and motor bolts for connecting the disc motors 120a and 120b. Similarly, the mounting holes 133a and 133b can be divided into first mounting holes 133a through which the housing bolts pass, and second mounting holes 133b through which the motor bolts pass. The first mounting holes 133a are located on the abutting surface 1312, and a plurality of the first mounting holes 133a surround the interface portion 1311 in a manner close to the interface portion 1311. A plurality of the second mounting holes 133b are arranged circumferentially and spaced apart in a manner close to the outer circumference of the connection plate 130.

[0081] In the step (b2), after the connection plate 130 is connected to the original housing 111a, 111b by using the structural connection surface 131, the housing bolt is passed through the first mounting hole 133a and screwed to the original housing 111a, 111b to tie the connection plate 130 and the original housing 111a, 111b together. The connection method between the original housing 111a, 111b and the structural connection surface 131 includes, but is not limited to, threaded connection, sleeve connection, clamping connection or spline connection, etc.

[0082] In step (b3), after the disk motors 120a, 120b are fixed to the motor connecting surface 132, the motor bolts are passed through the disk motors 120a, 120b until they are screwed into the second mounting holes 133b to tighten the connection between the disk motors 120a, 120b and the connecting disk 130.

[0083] The first mounting hole 133a can be a countersunk hole, so that the housing bolt can be inserted into the first mounting hole 133a from the motor connecting surface 132 to the structural connecting surface 131 to tie the connecting disk 130 and the original housing 111a, 111b together, and the housing bolt is hidden in the first mounting hole 133a to prevent the housing bolt from protruding outward and affecting the fit between the disc motor 120a, 120b and the motor connecting surface 132.

[0084] like Figure 1 As shown, the disc motors 120a, 120b include motor housings 121a, 121b and flanges 122a, 122b, wherein the flanges 122a, 122b are disposed on the end surfaces of the motor housings 121a, 121b connected to the original housings 111a, 111b. The disc motors 120a, 120b are connected to the connection disc 130 by means of the flanges 122a, 122b.

[0085] like Figure 4 and Figure 5 As shown, the structural connection surface 131 has an interface portion 1311 and an abutting surface portion 1312, and then the step (b2) includes:

[0086] The original housings 111 a and 111 b are screwed into the interface portion 1311 and fit onto the abutting surface portion 1312 .

[0087] The interface portion 1311 is located at the center of the structural connection surface 131, and the abutting surface portion 1312 is roughly annular and surrounds the interface portion 1311. When the original housings 111a and 111b are connected to the structural connection surface 131, the interface portion 1311 of the connecting disk 130 is threadedly connected to the original housings 111a and 111b until the abutting surface portion 1312 and the original housings 111a and 111b fit. The abutting surface portion 1312 is concave to form a plurality of grooves 13121, which can be used to reduce the weight of the connecting disk 130, and the connecting disk 130 has a small axial dimension, so as to avoid the weight of the connecting disk 130 affecting the supporting capacity of the original housings 111a and 111b for the disc motors 120a and 120b.

[0088] like Figure 4 and Figure 5 As shown, the motor connection surface 132 has a stopper portion 1321 and a receiving surface portion 1322, and the disc motors 120a and 120b include flanges 122a and 122b, and then the step (b3) includes:

[0089] The flanges 122 a and 122 b are embedded in the stopper portion 1321 and attached to the receiving surface portion 1322 .

[0090] The stop portion 1321 is located at the center of the motor connecting surface 132, and the receiving surface portion 1322 is roughly annular and surrounds the stop portion 1321. When the disc motors 120a and 120b are correspondingly connected to the motor connecting surface 132, the flanges 122a and 122b on the disc motors 120a and 120b are first embedded in the stop portion 1321 until they fit the receiving surface portion 1322.

[0091] In summary, the mixer truck's mixing top 200, energy recovery system 300 and air conditioning system 400 can all be modified using the above-mentioned modification method, that is, on the basis of the original drive device, the disc motor is used to replace the oil drive, and the air conditioning system 400 can be electrically driven, which can save fuel consumption to a large extent. And because the disc motor has small axial dimensions and light weight, there is no need for additional support, which reduces costs, and reduces the load of the original drive device housing on the motor, extending its service life. In addition, in the modification process of replacing the oil drive with the disc motor, the original connection end 112a on the original drive device can be directly used for connection, without the need to add additional structures, making the modification process simpler and reducing the modification cost at the same time, making it more suitable for the electric drive modification of existing fuel mixer trucks on the market.

[0092] like Figures 1 to 3 , Figure 6As shown, the mixer truck comprises:
