摘要： SUMMARY
The present invention concerns the implementation of production processes based on sheet metal molding, for the manufacture of some mechanical elements.
Among the mechanical elements that are very rarely made by sheet metal molding there are some pieces that are commonly defined as mechanical "arms".
A mechanical "arm" is an elongated mechanical element in which, typically, in correspondence with the two heads, there are holes, designed to couple this mechanical "arm" to other elements of a more complex mechanism. In particular, the mechanical "arms" used to transfer a movement, or a force, from one point of a mechanism to another, have non-negligible mechanical resistance requirements, they are relatively large, and have complex shape characteristics to be obtained through sequences of cuts and folds.
The present invention, while accepting the use of more complex molds than those normally used, aims to indicate a new production method that can be applied for the production of a number of mechanical "arms", even when their shape requires a greater thickness than that obtainable from cutting a single sheet metal and, above all, when requirements of mechanical resistance and precision of the holes are required, such that the known technique is still oriented towards production methods other than sequences of cuts, folding, drawing, i.e. processes of sheet metal molding.
These objectives can be achieved through a production method which involves manufacturing a mechanical "arm" starting from an initial flat piece of sheet metal, suitably shaped, so as to present a symmetry with respect to its longitudinal axis. The method then uses a special mold composed of a decomposable matrix and a pair of punches.
This special mold allows you to make the edges of the holes on the heads of the "arm" being processed, when the semi-finished product is already folded: this allows you to control the dimensions of these holes with excellent precision.
Furthermore, the method benefits from the dismantling of the matrix of the mold, to be able to free the "arm" from the matrix itself, even after the holes have been trimmed, preventing it from getting stuck inside the "arm".

摘要： An electric wheel system (1000) comprises: an electric wheel part (100) including a motor (20) and an inverter (10); a first arm which connects the bottom side of the electric wheel part and a vehicle body; and a second arm which connects the top side of the electric wheel part and the vehicle body. A motor housing (24) includes a first arm connecting part (25) connected to the first arm and a second arm connecting part (26) connected to the second arm. The inverter is disposed at a position overlapping a line segment connecting the first arm connecting part and the second arm connecting part. The motor housing includes a first fan-shaped area (1) with a central angle of 120° centered on the rotation axis of a rotor and a second fan-shaped area (2) with a central angle of 240° centered on the rotation axis of the rotor. The first arm connecting part is disposed in the first fan-shaped area disposed on the bottom side of the motor housing. Electrical connecting parts (15U, 15V, 15W) between the inverter and the motor are disposed in the second fan-shaped area disposed on the top side of the motor housing.

摘要： A suspension arm (1) includes a main body (2). The main body (2) includes a curved portion (2a) curved along a longitudinal direction and has a closed section. The main body (2) includes an inner side wall (2i), an outer side wall (2o), a first side wall (21), and a second side wall (22). The inner side wall (2i) corresponds to an inner side of a curve of the curved portion (2a). The outer side wall (2o) corresponds to an outer side of the curve of the curved portion (2a). The first side wall (21) connects one side edge of the inner side wall (2i) and one side edge of the outer side wall (2o). The second side wall (22) connects the other side edge of the inner side wall (2i) and the other side edge of the outer side wall (2o) and faces the first side wall (21). A thickness (ta) of the inner side wall (2i) is larger than a thickness (tb) of the outer side wall (2o). In sectional view of the main body (2) perpendicular to the longitudinal direction, each of a length of the first side wall (21) and a length of the second side wall (22) is longer than each of a length of the inner side wall (2i) and a length of the outer side wall (2o).
