[Prior Art] A motor vehicle that drives a rear wheel by a motor by a transmission mechanism, etc., is known. Please refer to FIG. 1 , which is a cross-sectional view showing the brushless spindle horse I and the electric motor vehicle transmission box installation; generally known that the transmission device 2 乂 the no-shaft motor M is the main power (four) into the drive mechanism 'via the transmission mechanism The power is transmitted to the rear casters, which in turn enables walking = electric motor vehicle's use of the hanger shaft suspension motor Μ on the frame and the hanger struts on the gearbox τ and the hanger struts 2 on the motor μ A heat sink 设置 disposed on the motor housing M2. - the middle motor Μ is stunned by a single rotation axis, and the generated power is thus outputted from the end of the rotating shaft R1 to the inside of the motor cymbal, and the rear side end thereof is supported by the rear bearing B1 press-fitted to the motor rear cover M1. The front position is circumvented on the front end side front sleeve B2 of the motor casing M2, and the front end side is exposed to the outside of the motor and is inserted into the transmission case τ' on the casing T1 of the transmission case τ. There is an outer bearing 扪 to support the exposed front end side of the rotating shaft R1, and the front end side is disposed on the transmission 3 M365603 to drive the 7L piece D, and a connecting member is arranged on the transmission driving element D, and the transmission is connected to the rear side by the linking member The drive element p and the clutch device K are supported by the drive shaft R2. Therefore, the power generated when the motor M rotates is transmitted to the transmission drive element p, the clutch device K, and the drive shaft R2 by the rotation shaft R1. The illustration discloses that the drive drive elements D, P are pulley elements' and the aforementioned linkages are drive belts. Since the above structure is to set the two bearings B1 and B2 in the rear cover and the motor outside the 1VQ and M2, the other bearing B3 is arranged on the transmission case τι, which are formed on different structures, so it is necessary to do it again when combining. Calibration will inevitably produce deviations, and assembly and wear will be performed on the rotating shaft R1. The right calibration error is too large, and deflection vibration is easy to occur during rotation. At the same time, the bearing B3 is pinched, resulting in disassembly and assembly between the motor casing and the transmission case: On the motor JV [the hanger post is placed on the heat sink, the heat dissipation effect of the heat sink is easy now] and the distance between the two hanger pillars is better.

The preferred motorless brushless spindle motor further includes a second bearing disposed adjacent the front end bearing to support the brushless spindle. The above objects and advantages of the present invention are readily apparent from the following detailed description of the embodiments of the invention. Tian Ran's creation allows for 5 M365603 differences on certain parts or arrangements of parts, but the details are turned over. In this manual, detailed explanations are given, and the construction is shown in the drawings. [Embodiment] The technical means by which this creation is used to achieve the above objectives are explained in detail below with the following implementation diagrams, and the rhyme is understood and recognized by the people. Please also refer to the section 5 and the 6' section of the section of the mine. The brushless spindle motor of the electric vehicle of the present embodiment is combined with the transmission case 1G (as shown in FIG. 6), and the brushless spindle motor for the electric vehicle includes a motor casing 2, a rear cover 3, and a brushless spindle 5. - front end bearing 6 and rear end bearing 8. The motor casing 2 has a hollow structure and has a front end 21 and a rear end 22; and a plurality of fin-shaped fins 23 are arranged around the outer periphery of the motor casing 2 to increase the heat dissipating area, thereby improving the heat dissipating effect. The rear cymbal 3 is disposed at the rear end 21 of the motor casing 2, and the rear cover 3 can be combined with the motor casing 2 as a single component, and the rear cover 3 is further provided with a bracket 3. The bracket 31 and the rear cover 3 are integrally formed. Compared with the conventional one, the bracket is integrally formed on the heat sink of the motor casing, and the created bracket does not affect the heat dissipation effect of the heat sink 'and the integrally formed structure can reduce the stress problem' and thereby increase the strength. In addition, since the bracket 31 is disposed at the rear cover 3, the bracket A2 is disposed on the heat sink H (as shown in FIG. 1), and the bracket 31 M365603 of the present invention is driven from the transmission I. The distance between the other brackets on the 4) is lengthened to increase the stability of the vehicle body. In addition, the front end 21 of the motor casing 2 extends outwardly in the axial direction thereof to form a two-member portion 42, and the front end portion 21 is further provided with a plurality of through holes 41 for connecting to the wires W of the controller (as shown in FIGS. 4 and 6). ), through the warp, the wire W is directed toward the motor back cover (as shown in FIG. 1). This creation causes the wire w to exit the front end perforation 41 of the motor casing 2 to prevent the motor from being mounted on the car. Exposed the wires when the body is in the body. ", the brush spindle 5 is inserted into a motor armature 9 in the motor casing 2, and one end (front end side) passes through the center of the front end 21 of the motor casing 2, and the brushless spindle 5 passes through the front end of the motor casing 2. The exposed end of the center of the 21 is connected to a driving element 1〇1 in a gearbox 1 (as shown in FIG. 6, while FIG. 6 shows that the driving element 1〇1 is a pulley); wherein the motor armature 9 Including - stator 91 and rotor 92, the stator % ring is disposed on the inner side wall of the motor casing 2, and the rotor 92 is ringed on the brushless main shaft 5. The front end bearing 6 is disposed in the neck portion 42 to support the brushless spindle The front end side of the fifth end is provided in the rear cover 3 by the bearing 8 to support the rear end side of the brushless spindle $. Since the front end side of the brushless spindle 5 passes through the front end 21 of the motor casing 2 and is driven The driving elements 101 in the case 10 are coupled (as shown in FIG. 6), so when the brushless spindle 5 is rotated to drive the driving elements 1〇1, the brushless spindle 5 is supported by the support of the front end bearing 6 and the rear end bearing 8.

The deflection vibration caused by the pulling force is used to achieve the best stability. Referring to Fig. 2 and Fig. 3, respectively, a perspective view and a cross-sectional view of the embodiment having the three-bearing of the present invention are shown. The spindle motor 1 further includes a second bearing 7. The second bearing 7 is formed with a distance adjacent to the front end bearing 6, so that the front portion of the brushless spindle 5 is in a double bearing support configuration, since the front end side of the brushless spindle 5 is passed through. The front end 21 of the motor casing 2 is coupled to the driving element 101 in the transmission case 10 (as shown in FIG. 4), so that when the brushless spindle 5 is rotated to drive the driving element 101, the front end bearing 6, the second bearing 7, and the rear are The support of the end bearing 8, together with the neck portion 42 provided at the front end 21 of the motor casing 2, is embedded in the casing 102 of the transmission case 10, so that the front end bearing 6 can be adjacent to the driving member 101 to avoid the interlocking member (Fig. Not shown) Rally The deflection vibration caused by the rotation of the brushless spindle 5 is more stable, and the stability is achieved. Further, since the front end bearing 6, the second bearing 7, and the rear end bearing 8 are all installed in the motor casing 2 Compared with the conventional one, one of the bearings is placed in the transmission case, that is, the bearing is set in different structures. This creation can reduce the calibration error of the M365603 less bearing axis during machining, and there is no difference between different structures. The pinning is easy to disassemble and install between the gearboxes.
