Problems solved by technology
In the prior art, due to the complex shape of the powertrain and the connection surfaces of the connecting parts of the connecting bracket are located on the same plane, only a small plane can be found on the powertrain to connect with the connecting bracket, so the stress is relatively concentrated. In the case of emergency braking of the vehicle, over a pit, etc., due to the action of inertia, the connecting bolts are easily damaged by force, which may easily cause the suspension bracket to fail

Embodiment Construction
[0009] A powertrain connection bracket, the upper part of the bracket body 10 has a suspension connection part 11 that is matched with the suspension bracket 1, and the lower part of the bracket body 10 has an overall body connection part 12 that connects the powertrain body. There are connection holes between the upper and lower end surfaces of 11 to pass through bolts for connecting the suspension bracket 1. The connecting part 12 of the overall body includes connecting units located at high and low positions, and bolts are arranged between the upper and lower end surfaces of the connecting units. Holes, the groove wall 15 and the bottom of the groove formed by curved ribs between the suspension connection part 11 and the overall body connection part 12 are connected to each connection hole and / or bolt connection hole, and the groove wall 15 and the bottom of the groove are connected to each other. The opening of the enclosed area points downwards.

The invention provides a power assembly connection bracket, the upper part of the bracket body has a suspension connection part that is matched and connected with the suspension bracket, the lower part of the bracket body has an assembly body connection part that connects the power assembly body, and the suspension connection part There are connection holes between the upper and lower end faces to connect the bolts for connecting the suspension brackets. The connection part of the total body includes connecting units located at high and low positions. Bolt connection holes are set between the upper and lower end faces of the connecting units. Between the connecting part and the connecting part of the main body, the groove wall and groove bottom made of curved ribs are connected to the connection holes and / or bolt connection holes, and the opening of the area surrounded by the groove wall and the groove bottom points Down. In the above scheme, the high and low dislocation connection units reduce the stress concentration and effectively reduce the stress relief of the connecting bolts, which effectively improves the structural strength of the connecting bracket. itself weight.
Description
technical field [0001] The invention relates to the technical field of automobile powertrain, in particular to a suspension bracket of a gearbox. Background technique [0002] The suspension system can effectively control and reduce the vibration transmission of the powertrain, improve the ride quality of the car, and reduce the shaking of the engine. The suspension system is also the connecting part between the powertrain and the body, and plays a supporting role in the powertrain. The connecting bracket of the powertrain is an important supporting part in the powertrain suspension system, and the connecting bracket of the powertrain is used to connect the powertrain and the suspension. [0003] The connecting bracket of the power assembly is connected with the power assembly through bolts, and generally there are 3-4 connecting parts between the connecting bracket and the power assembly. In the prior art, due to the complex shape of the powertrain and the connecting surf...
