[0033] By adopting the universal front enclosure structure for left and right steering wheels of the present invention, for a diesel manual transmission vehicle model, firstly, one end of the cab front suspension 2 is installed in the first installation area 11, and the other end is installed in the second installation area 12, so that the first installation area 11, the second installation area 12 and the third installation area 13 are arranged under the premise of ensuring the comfort of the vehicle; and when the front enclosure inner panel 1 is configured as a left-hand steering vehicle, the first installation area 11 is provided with a first assembly component, and the second installation area 12 is provided with a second assembly component; when the front enclosure inner panel 1 is configured as a right-hand steering vehicle, the first installation area 11 is provided with a second assembly component, the second installation area 12 is provided with a first assembly component, and the third installation area 13 is provided with a third assembly component. With such an arrangement, the front enclosure inner panel drawing forming mold for left and right-hand steering vehicles can be universal, and only left-hand steering or right-hand steering is made according to actual needs in subsequent processing, thereby improving the mold sharing rate, reducing the mold development cost, and effectively solving the problem of poor universality of the vehicle front enclosure structure in the prior art. By utilizing the common front enclosure structure for left and right rudder vehicles of the present invention, a set of front enclosure inner panel structures is adopted for both left and right rudder vehicles, and the low wind resistance styling requirements of the whole vehicle are met, while ensuring that the heat dissipation performance and electrical configuration requirements of the whole vehicle are met.

[0034] The cab front suspension 2 is installed on the front wall inner panel 1 and is symmetrical about the center line of the front wall inner panel 1. In order to ensure the comfort of the vehicle, the cab front suspension 2 is extended to the lower edge of the windshield and fixed to the front wall inner panel 1 by bolts. The position of the cab front suspension 2 directly affects the comfort of the whole vehicle. The front wall layout gives priority to the position of the cab front suspension 2, and the cab front suspension 2 is symmetrically arranged at the optimal position for the comfort of the whole vehicle. The other modules are arranged on the principle that the position of the cab front suspension 2 remains unchanged.

[0035] Specifically, the third assembly component includes a fifth mounting structure, and the fifth mounting structure is located in the middle of the front inner panel 1. At the same time, the fifth mounting structure of the left and right rudder vehicles is located at the same position, and both can be used to install the air conditioning module 3. This arrangement further improves the versatility of the front structure of the vehicle.

[0036] In this embodiment, the first installation area 11 includes a first installation beam 111, and the first assembly component includes a first installation structure and a second installation structure located on both sides of the first installation beam 111. The second installation structure is located on the side facing the third assembly component, and the first installation structure is located on the side away from the third assembly component. The first installation structure and the second installation structure are provided to facilitate installation of the vehicle module, and the first installation beam 111 is provided to facilitate installation of the cab front suspension 2.

[0037] Further, similarly, the second mounting area 12 includes a second mounting beam 121, and the second assembly component includes a third mounting structure and a fourth mounting structure located on both sides of the second mounting beam 121, wherein the third mounting structure is located on the side facing the third assembly component, and the fourth mounting structure is located on the side away from the third assembly component. The second mounting beam 121 is provided, which also facilitates the installation of the other end of the cab front suspension 2.

[0038] like Figure 1 As shown, when the front inner panel 1 is configured as a left-hand drive vehicle, the first installation structure can be used for the installation of the wiring harness docking box module 4, the purpose of which is to consider the convenience of connecting the chassis wiring harness to the cab and avoid the wiring harness from being suspended across and affecting the reliability of the whole vehicle; the second installation structure can be used for the installation of the expansion tank module 5, the purpose of which is to reduce the height of the floor from the ground and ensure the heat dissipation performance of the whole vehicle; the third installation structure can be used for the installation of the brake module 6 and the throttle module 7, wherein the brake module 6 includes a brake foot valve and a brake pedal bracket, the brake foot valve is connected to the front inner panel 1 through the brake pedal bracket, wherein the brake pedal bracket is a stamping structure and is fixed to the front inner panel 1 by bolts; the throttle solenoid valve of the throttle module 7 is arranged inside the cab, located on the left side of the brake module 6, and shares the brake pedal bracket with the brake foot valve; the fourth installation structure can be used for the installation of the clutch control module 8, wherein the clutch control module 8 is connected to the front inner panel 1 through the clutch pedal bracket, and the clutch pedal bracket is a stamping structure and is fixed to the front inner panel 1 by bolts.

[0039] like Figure 2As shown, when the front inner panel 1 is configured as a right-hand drive vehicle, the first mounting structure can be used to install the brake module 6 and the throttle module 7. Similarly, the throttle solenoid valve of the throttle module 7 is arranged on the left side of the front inner panel 1 with the brake module. The throttle module 7 of the left-hand and right-hand drive vehicles is the same; the second mounting structure can be used to install the clutch control module 8, wherein the clutch control module 8 of the left-hand and right-hand drive vehicles is the same. The third mounting structure can be used to install the expansion tank module 5, the purpose is also to reduce the height of the floor from the ground and ensure the heat dissipation performance of the whole vehicle; the fourth mounting structure can be used to install the wiring harness docking box module 4. The wiring harness docking box module 4 of the left-hand and right-hand drive vehicles is a mirror image relationship. In order to meet the electrical configuration requirements of the whole vehicle and ensure the low wind resistance of the whole vehicle, the wiring harness box adopts a conformal design method to make full use of the layout space and ensure that the clearance between the wiring harness box and the cab CAS (Class-A-Surface, A-class curved surface, is a professional term used in automobile design to describe high-quality appearance surfaces) surface maintains a clearance of more than 20mm.

[0040] It should be noted that in order to ensure the large rounded corner shape of the cab CAS, the brake foot valve of the right-hand drive vehicle needs to be rotated downward by 5° to ensure that the foot valve and the pipe bundle have a clearance of more than 20 mm with the CAS.

[0041] In this embodiment, the first mounting structure or the third mounting structure has a mounting pedal bracket, and the brake module 6 and the accelerator module 7 are both connected to the mounting pedal bracket. This arrangement further improves the versatility of the front structure of the vehicle.

[0042] This embodiment also provides a vehicle, including an air conditioning module 3, a brake module 6, a throttle module 7, a clutch control module 8, an expansion water tank module 5, a wiring harness docking box module 4 and a front enclosure structure common to left and right rudders in the above scheme, wherein the air conditioning module 3, the brake module 6, the throttle module 7, the clutch control module 8, the expansion water tank module 5 and the wiring harness docking box module 4 are all installed on the front enclosure inner panel 1. The vehicle of the present invention makes the front enclosure inner panel drawing forming die of left and right rudder vehicles universal for diesel manual transmission vehicles, and only makes it into left rudder type or right rudder type according to actual needs during subsequent processing, thereby improving the mold sharing rate, reducing the mold development cost, and effectively solving the problem of poor universality of the front enclosure structure of vehicles in the prior art. Using the front enclosure structure common to left and right rudders of the present invention, a set of front enclosure inner panel structures is adopted for left and right rudder vehicles, and the low wind resistance styling requirements of the whole vehicle are met, while ensuring that the heat dissipation performance and electrical configuration requirements of the whole vehicle are met.

[0043] Specifically, the volume of the expansion water tank module 5 is 14L-16L. In order to ensure the heat dissipation requirements of the whole vehicle and meet the low wind resistance shape of the cab, the expansion water tank is designed to follow the CAS surface of the cab. At the same time, the expansion water tank module 5 uses the front opening to extend part of the structure of the expansion water tank module 5 into the cab, making use of the space inside the cab. In this solution, the volume of the expansion water tank module 5 is set to 15L, which can not only ensure the heat dissipation requirements of the whole vehicle, but also meet the low wind resistance shape of the cab.

[0044] Specifically, the wiring harness docking box module 4 has a plurality of connectors. According to the EE (electronic and electrical) configuration requirements of the entire vehicle, the wiring harness docking box module 4 is guaranteed to have at least 15 connectors.
