In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art: when the drive assembly is placed on the suspension assembly, the flywheel housing of the engine in the drive assembly has a large bending moment, which in turn causes the flywheel housing to be easily damaged under the action of the large bending moment, affecting the service life of the flywheel housing. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] To this end, a first aspect of the present invention provides a drive system.

[0005] A second aspect of the present invention provides a vehicle.

[0006] In view of this, the first aspect of the present invention proposes a drive system for a vehicle, the drive system comprising: a drive mechanism, the drive mechanism comprising an engine, a gearbox and a motor, the engine comprising a body and a flywheel housing, one end of the flywheel housing is connected to the body, the other end of the flywheel housing is connected to the gearbox, and the gearbox is connected to the motor; a suspension mechanism, the suspension mechanism is used to be arranged on a frame of the vehicle, the suspension mechanism comprises a first suspension component, a second suspension component and a third suspension component, the first suspension component is connected to the flywheel housing, the second suspension component is connected to the gearbox and the motor, and the third suspension component is connected to the body.

[0007] The present invention provides a drive system that can be used for vehicles, specifically, hybrid engineering vehicles. The drive system includes a drive mechanism, which can be used to drive the vehicle to move. The drive mechanism includes an engine, a gearbox and a motor, wherein the output shafts of the gearboxes of the engine and the motor are connected to the input shaft of the gearbox, and the output shaft of the gearbox can be connected to the wheel axle of the vehicle to drive the wheel axle of the vehicle. That is, the drive mechanism can provide driving force through the engine or the motor, that is, the drive mechanism is a hybrid power mechanism.

[0008] Furthermore, the engine includes a body, and the output shaft of the body is connected to a flywheel. At the same time, the engine includes a flywheel housing, and the flywheel housing cover is arranged outside the flywheel to protect the flywheel. In addition, one end of the flywheel housing is connected to the body of the engine. Furthermore, one end of the gearbox of the drive mechanism is connected to the other end of the flywheel housing, and the motor of the drive mechanism is connected to the other end of the gearbox at the same time, thereby realizing the connection between the engine, the gearbox and the motor, that is, realizing the integrity of the drivable mechanism structure.

[0009] Furthermore, the drive system also includes a suspension mechanism, which is used to be arranged on the frame of the vehicle, and the drive mechanism is arranged on the suspension mechanism to support the drive mechanism, thereby ensuring the stability of the drive mechanism on the frame of the vehicle. Specifically, the suspension mechanism includes a first suspension component, a second suspension component and a third suspension component, and the first suspension component is connected to the flywheel housing, the second suspension component is connected to the gearbox and the motor, and the third suspension component is connected to the body of the engine. That is, the middle part and the front and rear parts of the drive mechanism are supported by the first suspension component, the second suspension component and the third suspension component respectively, thereby ensuring the bearing capacity of the suspension mechanism and improving the stability of the drive mechanism.

[0010] Furthermore, the first suspension system is connected to the flywheel housing of the engine, that is, the flywheel housing is directly placed on the first suspension system, so as to avoid the self-gravity of the drive mechanism and the flywheel housing of the engine causing bending moment on the flywheel housing. At the same time, the second suspension assembly and the third suspension assembly respectively support the engine body, the gearbox and the motor, that is, the drive mechanism is supported at both ends of the flywheel housing of the engine, so as to reduce the parts at both ends of the flywheel housing under the action of gravity, which causes the flywheel housing to generate a large bending moment. Specifically, according to the weight of the drive mechanism, the size of the drive mechanism and the position of the overall center of gravity of the drive mechanism, the position of the second suspension assembly and the third suspension assembly can be adjusted so that the bending moment generated by the flywheel housing of the engine is zero, thereby ensuring the service life of the flywheel housing to the greatest extent.

[0011] It is understandable that when the driving mechanism includes both an engine and a motor, the overall weight of the driving mechanism is relatively large. Therefore, by configuring the suspension mechanism to include a first suspension component, a second suspension component, and a third suspension component, the driving mechanism is supported simultaneously in the middle and front and rear parts of the driving mechanism, thereby achieving weight dispersion of the driving mechanism on the suspension mechanism, thereby increasing the bearing capacity of the suspension component and ensuring the stability between the heavier driving mechanism and the vehicle frame.

[0012] The drive system provided by the present invention includes a drive mechanism and a suspension mechanism. By setting an engine and a motor, the output of the hybrid power of the drive mechanism can be achieved, thereby improving the driving performance of the drive system. Further, by setting the suspension mechanism as a first suspension component, a second suspension component and a third suspension component, the drive mechanism can be supported at the middle and front and rear parts of the drive mechanism at the same time, achieving the weight distribution of the drive mechanism on the suspension mechanism, thereby improving the load-bearing capacity of the suspension component. At the same time, the first suspension component is set to be connected to the flywheel housing of the engine, so that the self-gravity of the drive mechanism and the flywheel housing of the engine can be avoided to cause bending moment on the flywheel housing. Further, the second suspension component and the third suspension component located on both sides of the first suspension component are matched, so as to reduce the large bending moment of the flywheel housing caused by the gravity of the parts at both ends of the flywheel housing, avoid the flywheel housing from being damaged due to excessive bending moment, and improve the service life of the flywheel housing.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0061] According to a first aspect of the present invention, Figure 1As shown, a driving system 100 is proposed, which is used for a vehicle. The driving system 100 includes a driving mechanism 102 and a suspension mechanism 114, wherein the suspension mechanism 114 is used to support the driving mechanism 102. The driving mechanism 102 includes an engine 104, a gearbox 106 and a motor 108. The engine 104 includes a body 110 and a flywheel housing 112. One end of the flywheel housing 112 is connected to the body 110, and the other end of the flywheel housing 112 is connected to the gearbox 106. The gearbox 106 is connected to the motor 108. The suspension mechanism 114 is used to be arranged on the frame of the vehicle. The suspension mechanism 114 includes a first suspension component 116, a second suspension component 118 and a third suspension component 120. The first suspension component 116 is connected to the flywheel housing 112, the second suspension component 118 is connected to the gearbox 106 and the motor 108, and the third suspension component 120 is connected to the body 110.

[0062] The present invention provides a drive system 100, which can be used for vehicles, specifically, can be used for hybrid engineering vehicles. The drive system 100 includes a drive mechanism 102, and the drive mechanism 102 can be used to drive the vehicle to move. Among them, the drive mechanism 102 includes an engine 104, a gearbox 106 and a motor 108, wherein the output shafts of the engine 104 and the gearbox 106 of the motor 108 are connected to the input shaft of the gearbox 106, and the output shaft of the gearbox 106 can be connected to the wheel axle of the vehicle to drive the wheel axle of the vehicle. That is, the drive mechanism 102 can provide driving force through the engine 104, and can also provide driving force through the motor 108, that is, the drive mechanism 102 is a hybrid power mechanism.

[0063] Further, the engine 104 includes a body 110, and the output shaft of the body 110 is connected to a flywheel. At the same time, the engine 104 includes a flywheel housing 112, and the flywheel housing 112 is covered on the outside of the flywheel to protect the flywheel. In addition, one end of the flywheel housing 112 is connected to the body 110 of the engine 104. Further, one end of the gearbox 106 of the drive mechanism 102 is connected to the other end of the flywheel housing 112, and the motor 108 of the drive mechanism 102 is connected to the other end of the gearbox 106 at the same time, thereby realizing the connection between the engine 104, the gearbox 106 and the motor 108, that is, realizing the integrity of the structure of the drivable mechanism 102.

[0064] Further, the drive system 100 also includes a suspension mechanism 114, which is used to be arranged on the frame of the vehicle, and the drive mechanism 102 is arranged on the suspension mechanism 114 to support the drive mechanism 102, thereby ensuring the stability of the drive mechanism 102 on the frame of the vehicle. Specifically, the suspension mechanism 114 includes a first suspension component 116, a second suspension component 118 and a third suspension component 120, and the first suspension component 116 is connected to the flywheel housing 112, the second suspension component 118 is connected to the gearbox 106 and the motor 108, and the third suspension component 120 is connected to the body 110 of the engine 104. That is, the middle part and the front and rear parts of the drive mechanism 102 are supported by the first suspension component 116, the second suspension component 118 and the third suspension component 120 respectively, thereby ensuring the load-bearing capacity of the suspension mechanism 114 and improving the stability of the drive mechanism 102.

[0065] It is understandable that when the drive mechanism 102 includes both the engine 104 and the motor 108, the overall weight of the drive mechanism 102 is relatively large. Therefore, by configuring the suspension mechanism 114 to include a first suspension component 116, a second suspension component 118, and a third suspension component 120, the drive mechanism 102 is supported simultaneously in the middle and front and rear parts of the drive mechanism 102, thereby achieving weight dispersion of the drive mechanism 102 on the suspension mechanism 114, thereby increasing the bearing capacity of the suspension component and ensuring the stability between the heavier drive mechanism 102 and the vehicle frame.

[0066] Furthermore, the first suspension system is connected to the flywheel housing 112 of the engine 104, that is, the flywheel housing 112 is directly placed on the first suspension system, so as to avoid the self-gravity of the drive mechanism 102 and the flywheel housing 112 of the engine 104 causing bending moment on the flywheel housing 112. At the same time, the body 110 of the engine 104, the gearbox 106 and the motor 108 are supported by the second suspension component 118 and the third suspension component 120 respectively, that is, the drive mechanism 102 is supported at both ends of the flywheel housing 112 of the engine 104, so as to reduce the large bending moment of the flywheel housing 112 caused by the gravity at both ends of the flywheel housing 112. Specifically, according to the weight of the drive mechanism 102, the size of the drive mechanism 102 and the position of the overall center of gravity of the drive mechanism 102, the positions of the second suspension assembly 118 and the third suspension assembly 120 can be adjusted so that the bending moment generated by the flywheel housing 112 of the engine 104 is zero, thereby ensuring the service life of the flywheel housing 112 to the greatest extent.

[0067] The drive system 100 provided by the present invention includes a drive mechanism 102 and a suspension mechanism 114. By providing the engine 104 and the motor 108, the output of the hybrid power of the drive mechanism 102 can be achieved, thereby improving the driving performance of the drive system 100. Further, by providing the suspension mechanism 114 with a first suspension component 116, a second suspension component 118, and a third suspension component 120, the drive mechanism 102 can be supported at the middle and front and rear parts of the drive mechanism 102 at the same time, achieving the weight distribution of the drive mechanism 102 on the suspension mechanism 114, thereby improving the bearing capacity of the suspension component. At the same time, the first suspension component 116 is configured to be connected to the flywheel housing 112 of the engine 104, so as to avoid the self-gravity of the driving mechanism 102 and the flywheel housing 112 of the engine 104 causing bending moment on the flywheel housing 112. Furthermore, the second suspension component 118 and the third suspension component 120 located on both sides of the first suspension component 116 are cooperated to reduce the large bending moment of the flywheel housing 112 at both ends of the flywheel housing 112 under the action of gravity, thereby avoiding damage to the flywheel housing 112 due to excessive bending moment, and improving the service life of the flywheel housing 112.
