Example five:

in a specific embodiment, the engine (corresponding to the engine 170 in the present application) and the transmission (corresponding to the transmission 180 in the present application) are combined into a rigid body through the connection mechanism 100 between the engine and the transmission, so that the bending moment of the flywheel housing is zero; meanwhile, the position of the rear suspension (equivalent to the first suspension 150 in the application) of the engine is moved backwards, and the distance between the front suspension (equivalent to the second suspension 160 in the application) and the rear suspension is increased, so that the load distribution of the suspension is uniform, and the large-tonnage power assembly is favorably born. The connecting mechanism 100 is designed into a bridge structure, and has the advantages of simple structure, low cost, high bearing capacity, convenient installation and disassembly and wide application range. The connecting bridge 110 is connected to the engine mount (corresponding to the second mount 130 in the present application) and the transmission mount (corresponding to the first mount 120 in the present application) by a highly rigid rubber mount, and the impact load of the rear mount can be reduced. Each part and the connection thereof in the embodiment are firm and firm, and can effectively carry out bearing and vibration isolation.

As shown in fig. 1 and 3, a front suspension bracket (corresponding to the suspension bracket 162 in the present application) of the front suspension system is fixed to the engine front suspension mounting hole by a bolt, a front suspension bracket (corresponding to the second bracket 166 in the present application) is welded to the vehicle frame, and the front suspension bracket are connected by a front suspension cushion (corresponding to the second cushion 164 in the present application) to perform a load-bearing and vibration-isolating function at the front end of the powertrain system.

Specifically, the front suspension bracket may be composed of a vertical plate, a bottom plate, and a reinforcing rib, and fixed to the engine by bolts. The front suspension bracket can be composed of a vertical plate, a bottom plate and reinforcing ribs and is fixed with the frame in a bolt or welding mode. The front suspension cushion can be made of natural rubber and is fixed with the front suspension bracket and the front suspension bracket through bolts. The engine bracket may be composed of a flywheel housing bracket (corresponding to the third bracket 140 in this application), a cylinder block bracket (corresponding to the second bracket 130 in this application), and connected by bolts. The connecting bridge 110 is composed of a vertical plate (equivalent to the mounting plate 114 in the present application), a bottom plate (equivalent to the connecting plate 112 in the present application), a connecting plate, and a rib plate (equivalent to the first reinforcing plate 116 in the present application), forms a bridge structure, and is connected to the rear suspension and the rubber suspension through bolts.

As shown in fig. 1 and 3, a rear suspension bracket (corresponding to the first bracket 154 in the present application) of the rear suspension system is welded to the vehicle frame, and is connected to the powertrain through a rear suspension cushion (corresponding to the first cushion 152 in the present application), so as to perform a load-bearing and vibration-isolating function at the rear end of the powertrain.

Specifically, the rear suspension bracket can be composed of a vertical plate, a bottom plate and a reinforcing rib and is fixed with the frame through bolts or welding modes. The rear suspension cushion can be made of natural rubber and is fixed with the rear suspension bracket and the front suspension bracket through bolts.

As shown in fig. 1 and 2, the cylinder bracket and the flywheel housing bracket of the connecting mechanism 100 are fixed to the rear suspension mounting hole of the engine by bolts, and the cylinder bracket and the flywheel housing bracket are connected together by bolts, so that the bearing capacity of the brackets is enhanced; the cylinder body support is of an I-shaped structure, and the bearing capacity of impact load generated by sudden acceleration and sudden braking of the whole vehicle is improved. The transmission bracket of the connecting mechanism 100 is fixed to the transmission through a bolt, the flywheel housing bracket and the transmission bracket are connected with the connecting bridge 110 through a rubber suspension (corresponding to the first elastic member 126 and the second elastic member 148 in the present application), and the connecting bridge 110 is connected with the rear suspension cushion.

Specifically, the cylinder bracket may be composed of a bottom plate (corresponding to the second back plate 132 in the present application), a vertical plate (corresponding to the second connecting plate 134 in the present application), and a rib plate (corresponding to the second reinforcing plate 136 in the present application), form an i-beam structure, and be fixed to the cylinder by bolts. The flywheel housing bracket can be composed of a vertical plate (equivalent to the third back plate 142 in the present application), a bottom plate (equivalent to the third connecting plate 146 in the present application) and a reinforcing rib, and is fixed with the flywheel housing through a bolt. The gearbox bracket can be composed of a vertical plate (equivalent to the first back plate 122 in the present application), a bottom plate (equivalent to the first connecting plate 124 in the present application) and a reinforcing rib, and is fixed with the gearbox through a bolt. The rubber suspension can be made of natural rubber and is connected with the flywheel shell bracket and the gearbox bracket through bolts.

Because the rigidity of the rubber suspension is high, the engine and the gearbox form a rigid body through the connecting mechanism 100, and the bending moment of the flywheel shell is zero; meanwhile, the rubber suspension plays a role in buffering impact load of the power assembly and protects the rear suspension cushion.

The connecting mechanism 100 moves the rear suspension cushion of the engine backwards, increases the distance between the front suspension cushion and the rear suspension cushion, enables the front and rear suspension loads to be distributed uniformly, and can carry out bearing and vibration isolation of a large-tonnage power assembly.
