APPLICANT:

TVS MOTOR COMPANY LIMITED, (an Indian Company)

at: “Chaitanya”, No. 12, Khader Nawaz Khan Road, Nungambakkam, Chennai – 600034, Tamil Nadu, India.

The following specification particularly describes the invention and the manner in which it is to be performed.

TECHNICAL FIELD
[0001] The present invention relates to a mounting assembly for mounting a powertrain of a vehicle and particularly but not exclusively relates to a mounting assembly for mounting a powertrain and having a rod assembly.

BACKGROUND
[0002] Conventional cargo vehicle has a powertrain which produces a high torque to carry heavy loads. Such a powertrain can have an internal combustion engine or an electric motor or both as a source of power. This powertrain is mounted on a vehicle frame with the help of a mounting assembly either in a suspended configuration or in a fixed configuration. In the suspended configuration of the power mounting, robust structural links are required for mounting, wherein the powertrain is suspended on a cradle member mounted on the vehicle frame. In the suspended configuration, the powertrain in its operation tends to produce a high torque which tends to induce a roll and jerks (hereinafter referred to as ‘torsional forces’) in the whole mounting assembly about a rolling axis which passes through the mounting assembly in the vehicle width direction. These torsional forces fatigue in the whole mounting assembly, which may lead to failure of or damage if left unaddressed.
[0003] To address the above problem, the existing solutions provide an engine mounting system which uses single block bushings, fixed to a separate mounting bracket on the bottom surface portion of a cradle member, which compromises the vibration-insulating performance. The single block bushings absorb the torsional forces acting on the mounting assembly during dynamic operations of the powertrain, which may prove to be effective against the torsional force acting in linear directions i.e. vertical or horizontal. However, the same is not sufficiently effective in absorbing the torsional forces acting in the angular direction of the mounting assembly, where the powertrain is supported by left and right engine mounts of the mounting assembly.
[0004] Additional problems also arise during the rolling action of the powertrain, resulting in lower amplitude vibrations at lower frequencies. In certain instances, high amplitude and frequency vibrations are also encountered. This requires an innovative powertrain mounting that not only addresses torsional forces but also enhances overall vibration insulation during engine operation.
[0005] Therefore, to address the above-mentioned problem the present invention proposes a rod assembly of a mounting assembly for mounting a powertrain of the vehicle.

The second housing portion is configured to receive a second bush and rotatably connected to a portion of the vehicle. The rod link is configured to connect the first housing portion and the second housing portion.
[0032] As per another embodiment of the present invention, the first housing portion is larger in size than the second housing portion and a diameter of the first bush is greater than a diameter of the second bush and the first housing portion, the second housing portion and the rod link are formed as an integral piece. The large size of the first housing provides more surface area to the accommodate the first bush and better dampening properties.
[0033] As per another embodiment of the present invention, the first bush and the second bush are configured to mitigate a plurality of transmission forces and a plurality of vibrations generated by the powertrain. In one embodiment the first bush is made up of a softer material to facilitate effective vibration absorption through increased surface area, enhanced flexibility, compliance, resilience, and damping characteristics. These combined attributes enable the torque rod assembly to efficiently mitigate vibrations generated by the powertrain, contributing to improved vehicle performance, comfort, and durability. In one embodiment of the present invention the second bush is made up of a hard material which provide it a structural rigidity and improved longevity of the rod assembly and enable it to withstand the torsional forces acting on it during dynamic load conditions of the power train of the vehicle.
[0034] As per another embodiment, the present invention relates to a mounting assembly for a powertrain of a vehicle, the mounting assembly comprises a cradle-member and a rod assembly. The cradle-member is configured to mount the powertrain via one or more powertrain mountings. The rod assembly is configured to mount the powertrain on a cross-member of the vehicle via a link member of the mounting assembly. Further, the rod assembly comprises a first housing portion, a second housing portion and a rod link. The first housing portion is configured to receive a first bush, where the first housing portion is configured to be rotatably linked to the powertrain via the link member. The second housing portion being configured to receive a second bush and is configured to be connected to one or mounting portions of the cross member.

[0035] As per another embodiment of the present invention, the mounting assembly comprises a link member configured to connect the powertrain with the rod assembly and comprises one or more link mounting portions and one or more device mountings. In one embodiment of the present invention the link member is joined with the powertrain via methods including but not limited to welding, screw joined and cast formed etc. The one or more link mounting portion are rotatably connected to the first housing portion. Therefore, when the torsional forces starts to act on the mounting assembly and start a rolling action, the second housing portion allow the link member to have an angular displacement and simultaneously stores the torsional forces through the first bushing. Hence, when the torsional forces are no longer in play the first bushing smoothly allows the link member to return to its original orientation, thereby enabling a comfortable operation of the mounting assembly. The one or more device mountings are configured to mount one or more components of the vehicle via one or more mounting members. In one aspect of the invention the one or more components of the vehicle includes an exhaust device of the vehicle.
[0036] As per another embodiment of the present invention, the cradle-member comprises one or more powertrain mountings, one or more tank mountings and one or more sleeves. The one or more powertrain mountings are configured to mount the powertrain. The one or more tank mountings are configured to mount a tank unit of the vehicle. In an embodiment of the present invention the one or more tank mountings may be used for mounting a fuel tank, a de-gas tank, a coolant and a lubricant oil tank etc. The one or more sleeves are linked to a frame of the vehicle via the one or more dampers of the mounting assembly. In an embodiment of the present invention the one or more dampers are sandwiched between the one or more sleeves and the frame. In another embodiment of the present invention, the one or more dampers mounted on the frame via methods including but not limited to welding, by screw means etc.
[0037] As per another embodiment of the present invention, an air intake system, is positioned in close to the cradle member. This configuration is to optimize space utilization within the vehicle while ensuring efficient airflow through the air intake system. The cradle member is carefully engineered to maintain a sufficient dynamic clearance with the air intake system, ensuring that there is ample space for airflow without any obstruction or interference. This clearance is essential for optimizing the performance and efficiency of the air intake system.
[0038] As per another embodiment of the present invention, a carburettor is positioned very close and above the cradle member. This configuration is intended to facilitate ease of serviceability, allowing for convenient access to the carburettor while the powertrain remains installed in the vehicle at a ground level.
[0039] As per another embodiment of the present invention, the first bush enables a first predetermined angular displacement (?1) of the mounting assembly along a rolling axis (X-X’) generated from operations of the powertrain and the second bush enables the first housing to have a second predetermined angular displacement (?2) along an axis (Y-Y’). The rolling axis (X-X’) is indicative of an axis along the width of the vehicle and the axis (Y-Y’) is an axis vertical to the rolling axis (X-X’).
[0040] In an embodiment the first bush is made up of a soft material which is capable of absorbing torsion forces and vibrations generated during the operations of the powertrain. Therefore, in a dynamic load situation the first bush absorbs the torsional forces and enable the mounting assembly to have a controlled angular displacement (?1) along a rolling axis measured with a horizontal surface which may be road. In another the second bush is made up of hard material which is capable of withstanding the torsional loads and vibrations acting on the mounting assembly during dynamic load conditions, this construction of the second bush allow it to provide a robust link between the power train and a frame of the vehicle.
[0041] As per another embodiment of the present invention, the first housing portion is configured to be displaced for a predetermined distance (D) along a vertical axis (Y-Y’). In dynamic load conditions the powertrain induces a rolling toque which tends to rotate the mounting assembly along a rolling axis (X-X’), in this situation second bush allows the rod assembly to pivot along a vertical axis (y-Y’) and since the first housing portion is rigidly linked with the second housing portion, the first bushing is displaced vertically for a predetermined displacement (D). The above-mentioned parameters such as the first predetermined angular displacement (?1), the second the predetermined angular displacement (?2) and the predetermined displacement may vary based on characteristics such as load capacity, engine displacement, power output etc. of the powertrain. For example the first predetermined displacement (?1) will be greater for a powertrain having an engine displacement of 500 cubic centimeter than for an engine displacement of 300 cubic centimeters.
[0042] As per another embodiment of the present invention, the cradle-member comprises one or more bends to accommodate the powertrain. The one or more bends may be of varying characteristics, which can be configured to accommodate the powertrain of varying sizes.

[0054] Figures 1 and 2 are taken together for discussion. A rod assembly (300) of a mounting assembly (200) is disclosed. The mounting assembly (200) (shown in Figure 5(b)) is used for mounting a powertrain (400) of a vehicle (100) (shown in Figure 10). When the powertrain (400) is mounted using the mounting assembly (200), the rod assembly (300) forms one part of the mounting assembly (200), whereby the rod assembly (300) enables a connection between the powertrain (400) and a cross member (103) of the frame (101) of the vehicle (100). The rod assembly (300) is configured to mitigate the torsional forces and vibrations from the powertrain (400). The rod assembly (300) comprises a first housing portion (301), a second housing portion (302) and a rod link (305). The first housing portion (301) is configured to receive a first bush (303) and is also configured to be rotatably connected to the powertrain (400). The second housing portion (302) is configured to receive a second bush (304) and rotatably connected to a portion of the vehicle (100). The rod link (305) is configured to connect the first housing portion (301) and the second housing portion (302). In this embodiment, the first housing portion (301) and second housing portion (302) are substantially configured in a circular profile to accommodate the first bush (303) and the second bush (304). However, the housing portions (301, 302) can also be configured in other shapes as well.
[0055] The first housing portion (301) is larger in size than the second housing portion (302) and accordingly diameter of the first bush (303) is greater than a diameter of the second bush (304). Further, the first housing portion (301), the second housing portion (302) and the rod link (205) are formed as an integral piece. The large size of the first housing provide more surface area to the accommodate the first bush (303). The first bush (303) and the second bush (304) are configured to mitigate a plurality of transmission forces and a plurality of vibrations generated by the powertrain. In one embodiment the first bush (303) is made up of a softer material to facilitate effective vibration absorption through increased surface area, enhanced flexibility, compliance, resilience, and damping characteristics. These combined attributes enable the torque rod assembly to efficiently mitigate vibrations generated by the powertrain, contributing to improved vehicle performance, comfort, and durability. In one embodiment of the present invention the second bush (304) is made up of a hard material which provide it a structural rigidity and improved longevity of the rod assembly (300) and enable it to withstand the torsional forces acting on it during dynamic load conditions of the power train (400) of the vehicle (100).
[0056] As shown in Figure 2 (a) to 8, a mounting assembly (200) for a powertrain (400) of a vehicle (100) is disclosed. The mounting assembly (200) comprises a cradle-member (201) and the rod assembly (300). The cradle-member (201) is configured to mount the powertrain (400) via one or more powertrain mountings (205). In an embodiment, the powertrain (400) may include but not limited to an internal combustion engine, an electric motor, and a hybrid drive of the internal combustion and electric motor. The rod assembly (300) is configured to mount the powertrain (400) on a cross-member (103) of the vehicle (100) via a link member (202) of the mounting assembly (200). As shown in Figure 5 (a) and 5 (b), the link member (202), on its one end, is connected to the crankcase (401) of the powertrain (400) with the rod assembly (300). On the other end, the link member (202) is rotatably connected to the rod assembly (300) via one or more link mounting portions (203).
[0057] The rod assembly (300) comprising the first housing portion (301), the second housing portion (302) and the rod link (305) along with the cradle member (201) provides three point mountings to suspendedly mount the powertrain (400). The first housing portion (301) has an inner surface which is circular in profile in one embodiment that receives a first bush (303). The first housing portion (301) is configured to be rotatably connected to the powertrain (400) via the link member (202). The second housing portion (302) is configured to receive a second bush (304) and is configured to be connected to one or mounting portions (106) of the cross member (103). The one or more mounting portions (106) are disposed in the middle of the cross member (103). During the cranking of an engine of the powertrain (400) a rolling torque is produced which tends to roll the whole mounting assembly (200) along a roll axis (X-X’) (shown in Figure – 6). The link member (202) of the mounting assembly (200) is configured to connect the powertrain (400) with the rod assembly (300). The link member (202) comprises one or more link mounting portions (203) and one or more device mountings (204). The one or more link mounting portion (203) are rotatably connected to the first housing portion (301).
[0058] During the rolling of the mounting assembly (200), the link member (202) starts to rotate along with it, thereby rotating the first bush (303). The configuration of the first bush (303) is such that the first bush (303) absorbs the torsional forces and vibrations generated during rolling of the mounting assembly (200) and rotate along a vertical axis (Y-Y’) via the second bush (304). Thereafter, when the powertrain (400) is turned off, the forces absorbed by first bush (303) and the second bush (304) allows the whole mounting assembly (200) to return to its original state in a smooth manner. The one or more device mountings (204) are configured to mount one or more components (105) of the vehicle (100) via one or more mounting members (209). In an embodiment the one or more components may be an exhaust device such as but not limited to catalytic convertor.
[0059] As shown in Figure 5(b), the cradle-member (201) comprises one or more powertrain mountings (205), one or more tank mountings (206) and one or more sleeves (207). The one or more powertrain mountings (205) are configured to mount the powertrain (400). The one or more powertrain mountings (205) are located in the middle of the cradle member (201). In an embodiment, the powertrain (400) is suspended on the one or more powertrain mountings (205). The one or more tank mountings (206) are configured to mount a tank unit of the vehicle (100). As per an embodiment, the tank unit may include but is not limited to a fuel tank, a coolant tank, a lubrication oil tank, a de-gas tank, a pressure reducer apparatus etc. In another aspect of the invention, where the vehicle (200) is an electric vehicle and the powertrain (400) comprises an electric motor, it is possible that the one or tank mountings (206) are configured to mount other components such as tool kits, storage units, or other components relevant to the electric vehicle. The one or more sleeves (207) are linked to a frame (101) of the vehicle (100) via the one or more dampers (208) of the mounting assembly (200). The one or more dampers (208) which is sandwiched between the one or more sleeves (207) of the cradle member (201) and a cradle mounting (107, shown in Figure 9), contribute in absorbing the torsional forces acting on the mounting assembly (200) during the operation of the powertrain (400) and provides a cushioning effect to the mounting assembly (200), thereby making the operation of the vehicle (100) smooth and comfortable. The one or dampers (208) may be made of conventionally known materials such as rubber, plastic or other known polymers with properties to absorb vibrations. Further, the cradle-member (201) comprises one or more bends (201A, 201B) to accommodate the powertrain (400). These one or more bends (201A, 201B) can vary based on the characteristic and configuration of the powertrain (400), and may be used for mounting powertrains which are different shape, size and characteristics. For example in one embodiment the one or more bends (201A, 201B) may be configured to mount and internal combustion engine and in another embodiment the one or more bends (201A, 201B) may be configured to mount an electric motor. Further the bend configuration of the cradle member (201) allows for an easy access of the one or more components (105) of the vehicle (100).
[0060] As shown in Figure 7, the first bush (303, shown in figure 1) enables a first predetermined angular displacement (?1) of the mounting assembly (200) along a rolling axis (X-X’) generated from operations of the powertrain (400) and the second bush (304) of the second housing portion (302) enables the first housing (301) to have a second predetermined angular displacement (?2) along an axis (Y-Y’). The rolling axis (X-X’) is indicative of an axis along the width of the vehicle (100) and the axis (Y-Y’) is an axis vertical to the rolling axis (X-X’). During the operation of the powertrain, the first predefined angular displacement (?1) and the second predefined angular displacement (?2) may be directly proportional to the amount of rolling torque generated by the powertrain. For example, a value of the first predefined angular displacement (?1) and the second predefined angular displacement (?2) generated by a powertrain (400) with a bigger engine, for example, an engine with a displacement of 1000 cubic centimeters, will be greater than a value of the first predefined angular displacement (?1) and the second predefined angular displacement (?2) generated by an engine with a smaller displacement, for example, 350 cubic centimeters.. Therefore, the configuration of the rod assembly (300) may vary based on the torque output of the powertrain (400).
[0061] The first housing portion (301) is configured to be displaced for a predetermined distance (D) along a vertical axis (Y-Y’) during the operations of the powertrain (400).
