Definitions
- the present invention relates to the field of automotive assembly, and more particularly to a suspension mounting bracket for use in powertrain installation on an automated production line using an AGV trolley. Background technique
- the Automated Guided Vehicle is widely used.
- the front-mounted transverse power-generating car adopts the left and right suspension arrangements.
- the AGV trolley can only lift the powertrain upwards according to the Z-direction of the whole vehicle. Therefore, in order to effectively position the powertrain when it is lifted, the powertrain must have a positioning stud parallel to the Z-direction (body height direction) of the vehicle.
- the gearbox is placed on the AGV trolley, the cushioning cushion assembly is first installed on the body sheet metal, and the suspension mounting bracket is fastened to the cushioning cushion assembly. After the AGV trolley is in place, it is lifted.
- the powertrain allows the positioning stud to pass through the locating hole on the suspension mounting bracket.
- the positioning stud can be parallel to the Z direction of the vehicle in the early stage of design.
- the new model uses a mature gearbox, due to factors such as the angle between the drive shaft and the layout space, the original positioning stud of the gearbox has an angle ⁇ (ie, not parallel) with the Z direction of the vehicle, which will cause the AGV car to lift.
- ⁇ ie, not parallel
- the powertrain is upgraded, it is difficult for the positioning stud to pass through the positioning hole, which is difficult to assemble.
- the object of the present invention is to solve the problem that the positioning stud has an angle with the slanting direction when the mature gearbox is used, so that the positioning stud is difficult to pass through the locating hole when the AGV trolley lifts the powertrain, which causes difficulty in assembly.
- the present invention provides the following technical solutions:
- a suspension mounting bracket comprising:
- the bracket body has a gearbox connecting portion and a damper cushion connecting portion;
- the gearbox connecting portion is provided with a gearbox positioning hole, and a side surface of the damper cushion connecting portion is recessed to form a positioning groove and a damper cushion connecting plate, the positioning slot is closed at one end and the other end is closed, the damper cushion connecting plate is provided with a damper cushion mounting hole, and the symmetry axis of the positioning slot and the gearbox locating hole There is an angle between the central axes.
- the bracket body is a cast integrally formed piece.
- the open end of the positioning groove is V-shaped.
- the suspension mounting bracket further includes a baffle and a nut, and the other side of the damper cushion connecting portion opposite to the positioning slot is recessed to form a nut limiting slot, and the damper cushion connecting plate Located between the positioning slot and the nut limiting slot, the baffle has at least one pair of nut clamping plates, and the nut clamping plate defines a hole, the nut clamping plate clamping the nut, the baffle After being mounted on the damper cushion connecting portion, the nut is located in the nut limiting slot, and the threaded hole of the nut, the hole between the nut clamping plate, and the damper cushion mounting hole Through.
- the width of the nut limiting slot satisfies the following inequality:
- W is the width of the nut limiting groove
- D1 is the distance between the opposite sides of the nut
- D2 is the diagonal length of the nut.
- the nut is a square nut.
- the baffle is a stamped one-piece.
- the angle between the axis of symmetry of the positioning groove and the central axis of the gearbox positioning hole is equal to the angle ⁇ .
- the positioning groove is oriented toward the slanting direction, that is, the suspension mounting bracket converts the non-twisted parallel assembly of the positioning stud into the locating groove.
- Parallel assembly eliminates the need to change the gearbox housing without adding transition brackets, which reduces design cycle times and reduces production costs.
- the V-shaped positioning groove opening facilitates the entry of the aluminum core of the cushioning cushion assembly into the positioning groove during assembly.
- the fastening effect by the nut and the screw is better, and the baffle clamping nut is mounted on the shock absorbing pad connecting portion, and the nut is located in the nut limiting groove, so that the suspension mounting bracket and the shock absorbing cushion When the assembly is connected, the nut does not follow the screw rotation during the tightening of the screw, and the fastening is more convenient.
- the width of the nut limiting groove is larger than the distance between the opposite sides of the outer contour of the nut, the nut has a certain adjustment margin in the nut limiting groove under the clamping of the baffle, thereby avoiding processing errors,
- the assembly error causes the threaded hole of the nut, the hole between the nut splint, and the mounting hole of the damper cushion to be incapable of penetrating, which is convenient for assembly.
- the width of the nut limiting groove is smaller than the distance between the diagonal lines of the outer contour of the nut, even if the screw is deformed by tightening the screw with a large torque, the rotation limit of the nut by the nut limiting groove is not affected.
- the square nut is used to facilitate the tightening of the bolts, to prevent the connection from being loosened, and to improve the reliability of the connection.
- bracket body is integrally formed by casting, and then the hole is opened, which is convenient to process and has low cost.
- baffle is stamped and formed with the same advantages.
