Abstract

A motor mounting for mounting a D.C. motor in an automobile body structure comprises a casing for the motor. The casing is constituted by a pair of casing halves and one of the casing halves is an integral part of the automobile body structure.

Claims

1. In combination with a vehicle having structural body parts, an improved electrical motor housing assembly supporting an armature and an output shaft comprising:

a panel member having a primary configuration to form a structural portion of the vehicle body and an integral secondary configuration to form a recess that provides a first motor housing part with a first flat rim encircling the recess, the flat rim positioned inward and separate from the periphery of the primary configuration;

a second motor housing part having a complementary configuration to the first motor housing part having a second flat rim complementarily to the first flat rim at the outer edge of the second housing part, and

means for connecting the first and second housing part together for abutment of their flat rims and to locate and position the armature and output shaft whereby the assembling of the panel member to perform its primary configuration function relative to the vehicle body also precisely locates the relative position of the motor and forms an operative portion of the motor housing.

2. The invention of claim 1 wherein the motor includes field magnetic pieces, and the panel member recess has a cavity shape to support the field magnetic pieces.

3. The invention of claim 1 further including a motor transmitting mechanism for transmitting the rotational force of the output shaft to an externally driven member, the panel member recess has a cavity shape to support the motion transmitting mechanism.

4. In combination with a vehicle having structural body parts, an improved electrical motor housing assembly supporting an armature, an output shaft, bearings, field magnet pieces, and contact brushes, comprising:

a panel member having a primary configuration to form a structural portion of the vehicle body and a secondary configuration to form a recess that provides a first motor housing part, the recess being divided into a plurality of separate cavities, each of a configuration to support a portion of the electrical motor parts, such as bearings field magnet pieces and contact brushes;

a second motor housing part having a complimentary configuration to the first motor housing part, and

means for connecting the first and second housing part together to locate and position the armature and output shaft whereby the assembling of the panel member to perform its primary configuration function relative to the vehicle body also precisely locates the relative position of the motor and forms an operative portion of the motor housing.

5. The invention of claim 4 further including a sealing groove positioned on one of the first and second flat rims.

6. The invention of claim 5 wherein the plane of the panel member is approximately in the same plane as the bottom of the recess, and the plane of the first flat rim is approximately parallel and offset from the panel member.

7. A motor mounting in an automobile body structure for a D.C. motor including a motor shaft with an armature and a commutator mounted adjacent each other ont the motor shaft for rotation therewith, a pair of spaced contact brushes slidingly engaged with the commutator for supplying electrical power to the armature through the commutator, at least one pair of field magnet pieces opposite in polarity to each other and encircling the armature, comprising:

a casing for accomodating all of said motor shaft with the commutator and armature thereon,

a holder for holding the contact brushes and said field magnet pieces therein, said casing comprising casing halves, one of said casing halves being an integral part of the automobile body structure and having a shaped cavity subdivided into first, second, third and fourth recesses for accomodating respective portions of the brush holder, field magnet pieces, bearings for the motor shaft and a motion transmitting mechanism for transmitting the rotational force of the motor shaft to an external driven element, the other of the casing halves being constituted by a cover member and having a shaped cavity defined therein for attaching respectively the other portions of the brush holder, field magnet pieces, bearings and the motion transmitting mechanism, said respective cavities being non-symmetrical.

8. In combination with a vehicle having structural body parts, an improved electrical motor housing assembly supporting an armature, an output shaft, bearings, field magnet pieces, and contact brushes, comprising:

a press stamped panel member having a primary configuration to form a structural portion of the vehicle body and a secondary configuration integral with the primary configuration to form a recess having a support wall that provides a first motor housing part, the recess being divided into a plurality of separate cavities, each cavity of a configuration to support a portion of the electrical motor parts, such as bearings, field magnet pieces and contact brushes, at least some of the cavities further providing integral supporting pawls extending from the cavity support wall for positioning some of the motor parts in an operative position, the panel member further providing an integral encircling flat rim section that extends around the peripheral of the secondary configuration with an integral sealing groove positioned on the flat rim section;

a second motor housing part having a complementary configuration to the first motor housing part including a second recess having a plurality of separate cavities, each of a configuration to support a portion of the electrical motor parts, and a second flat rim section encircling the second recess and complementarily to the first motor housing encircling flat rim;

sealing means for the sealing groove, and

means for connecting the first and second housing parts together to locate and position the armature and output shaft and close the sealing groove to seal the motor within, whereby the assembling of the panel member to perform its primary configuration function relative to the vehicle body also precisely locates the relative position of the motor and forms an operative portion of the motor housing.
