Electric motor assembly for a motor vehicle and brake
An electric motor assembly for a motor vehicle and brake has an engine cartridge with a stator connected to an engine casing. The engine cartridge also has a rotor connected to a wheel shaft. The assembly also has a disc of a disc brake connected to the wheel shaft. The assembly also has a disc brake caliper arranged astride the disc and connected to the engine casing.
1. An electric motor assembly for a motor vehicle and brake comprising:
an engine cartridge comprising a stator connected to an engine casing;
said engine cartridge further comprising a rotor connected to a wheel shaft;
said assembly further comprising a disc of a brake disc connected to said wheel shaft;
wherein said assembly further comprises a disc brake caliper positioned astride said disc and connected to said engine casing;
said assembly comprises a fork in one piece with said engine casing;
said wheel shaft forms an inner bearing race; and
said inner bearing race is joined to a wheel bearing; and
said engine casing is keyed onto said wheel bearing.
2. The assembly according to claim 1 , wherein
said disc brake disc is placed parallel or coplanar with said fork of a motor vehicle and facing said engine cartridge; and
said disc brake disc is placed between said fork and said engine cartridge.
3. The assembly according to claim 1 wherein:
the assembly comprises a first half-caliper firmly connected to, or in one piece with said fork or said engine casing;
said assembly further comprising an associable opposite second half-caliper associated with said first half-caliper so as to place said caliper astride the brake disc.
4. The assembly according to claim 1 wherein:
said engine casing comprises a support plate keyed on said wheel bearing;
said engine casing further comprises a stator housing attached circumferentially to said support plate; and
said stator housing comprises stator windings and stator laminations arranged circumferentially on it.
5. The assembly according to claim 4 wherein:
said rotor comprises a rotor ring to which permanent magnets are associated facing said stator windings and stator laminations; and
said rotor ring is attached to said wheel shaft; and
said wheel shaft comprises a first wheel flange to which said rotor ring and a facing second rotor flange is attached, to which said disc brake disc is connected.
6. The assembly according to claim 5 wherein:
said assembly comprises a bearing cartridge wherein said bearing cartridge comprises:
an inner bearing race comprising said first wheel flange to which said rotor ring is connected and suitable to be connected to a hub of a wheel, and
said inner bearing race comprises a second wheel flange to which said disc brake disc is connected; and
said bearing cartridge comprises an external bearing race onto which said support plate is keyed.
7. The assembly according to claim 1 wherein:
said engine casing comprises a support plate to which a stator housing is connected and thereby supported, sealing so as to close the casing on a sealing flange of the rotor; and
said engine casing supports said disc brake caliper; and
said engine casing is keyed on a wheel bearing placed on said wheel shaft.
8. The assembly according to claim 1 wherein:
said engine cartridge is connected to a wheel of a motor vehicle via an inner race bearing made on said wheel shaft.
9. The assembly according to claim 1 , wherein said wheel shaft is supported to rotate about said engine casing.
10. The assembly according to claim 1 , wherein said rotor comprises a rotor sealing flange and in which said stator housing is facing and sealed to said rotor sealing flange.
