Problems solved by technology
However, in the process of installing this kind of engine mount, affected by the static imbalance of the power unit, the power unit will deflect relative to the frame under the action of its own weight, which makes the engine mount appear different from the V-shape during the installation process. Problems encountered in the installation of the suspension device, resulting in increased difficulty in the installation of the entire powertrain and reduced installation efficiency

Embodiment Construction
[0030] The embodiment of the installation method of powertrain among the present invention: comprise the following steps:
[0031] Step 1, the suspension device is installed between the power unit and the vehicle frame in a locked state, the suspension device includes a fixing part fixed on the vehicle frame, a floating part fixed on the power unit and a clamp fixed on the fixed The elastic part between the fixed part and the floating part, when the suspension device is in the locked state, the fixed part and the floating part are detachably connected through the connecting part;
[0032] Step 2. After installing the suspension devices between the power unit and the frame, remove the connecting parts from between the fixed parts and the floating parts. The floating parts can float relative to the fixed parts, and the suspension devices are in a floating state .
[0033] The embodiment of automobile among the present invention: as Figure 3~Figure 8 As shown, the automobile i...

The invention discloses a power assembly installation method, a suspending device and a vehicle. The suspending device is installed between a power device and a vehicle frame in a locking state, so that when a power assembly is installed, although the power device can still apply the stress to the suspending device under the static unbalance action, a floating part of the suspending device in the locking state cannot move relative to a fixing frame, the power device is ensured not to move relative to the vehicle frame, and thus when the suspending device which is post-installed carries out installation operation, the position of the power device is consistent with a set position without needing regulation. Therefore, installation of the power assembly can eliminate a procedure of aligning the position of the power device in the process of post-installing the suspending device, and thus the efficiency of power assembly installation is accelerated, and the assembly period of the whole vehicle is also shortened.
Description
technical field [0001] The invention relates to a power assembly installation method, a suspension device and an automobile. Background technique [0002] At present, the powertrain suspension system of passenger cars with retarders generally adopts a six-point arrangement. Two suspension devices are installed at the engine pulley end, flywheel housing, and retarder respectively. Among them, the front suspension The rear mount (at the end of the engine pulley) mostly adopts a V-shaped layout, the rear mount (at the flywheel housing) mostly adopts a horizontal layout, and the auxiliary support (at the retarder) mostly adopts a V-shaped layout. The rear suspension in the form of flat arrangement generally adopts composite structural rubber pads (such as figure 1 As shown), the horizontal suspension device includes a fixed seat 101 fixed on the vehicle frame and a floating seat 102 fixed on the engine, and a block-shaped elastic body 103 is interposed and fixed between the fix...
