Detailed Description
Fig. 1 is a side view of a vehicle drive structure according to an embodiment of the present invention. Referring to fig. 1, the driving structure 100 for a vehicle of the present embodiment includes a knuckle 110, an arm 120 and a driving device 130. The knuckle 110 rotatably supports an axle 50 of a vehicle, the axle 50 being, for example, a turning shaft of a wheel of the vehicle, which extends, for example, in a width direction X of the vehicle in a state where the wheel is not steered. The arm 120 is connected to a front side of the knuckle 110 in the front-rear direction Y of the vehicle, and is used to steer the wheel by the knuckle 110, for example. The driving device 130 is disposed on the knuckle 110 and located between the axle 50 and the arm 120, and the driving device 130 is used for driving the brake caliper 60 to actuate so as to apply a braking force to the disc 70 of the wheel. The drive device 130 and the brake caliper 60 are disposed on the front side of the knuckle 110 in the vehicle front-rear direction Y as shown in fig. 1, and are relatively close to the inertial center of gravity of the overall structure shown in fig. 1.
Specifically, the driving device 130 includes a motor 132 and a reduction mechanism 134. The motor 132 is connected to the caliper 60 and drives the caliper 60. The speed reduction mechanism 134 is connected to the motor 132 and serves to reduce the rotation of the motor 132. The reduction mechanism 134 may include a reduction gear. As shown in fig. 1, the motor 132 is located above the speed reduction mechanism 134 in the vertical direction Z of the vehicle. That is, the speed reduction mechanism 134 is located below the motor 132. Accordingly, even if oil (e.g., gear oil) of the speed reduction mechanism 134 drops or flows downward, it does not fall to the motor 132. Therefore, it is possible to avoid adverse effects on the motor 132 due to the oil of the reduction mechanism 134 dropping down to the motor 132.
Further, the knuckle 110 and the arm 120 of the present embodiment are fixed to each other at a fixing point F shown in fig. 1. The driving device 130 is located above the arm 120 in the vertical direction Z of the vehicle, and at least a part of the driving device 130 overlaps the fixed point F between the knuckle 110 and the arm 120 in the vertical direction Z. Fixing the driving unit 130 near the fixing point F between the knuckle 110 and the arm 120 as described above can improve the rigidity of the entire structure.
Further, in the present embodiment, the knuckle 110 has a front wall portion 112 on the front side in the front-rear direction Y of the vehicle, and the front wall portion 112 includes a first wall portion 112a, a second wall portion 112b, and a connecting portion 112 c. The first wall portion 112a extends in the vertical direction Z of the vehicle, the second wall portion 112b extends in the front-rear direction Y of the vehicle, and the connecting portion 112c connects between the first wall portion 112a and the second wall portion 112b to constitute a recess in the front wall portion 112. At least a part of the drive device 130 overlaps the connecting portion 112c in the front-rear direction Y of the vehicle as shown in fig. 1. Accordingly, the drive device 130 can be made to abut compactly against the knuckle 110 at the recess in the front wall portion 112, and the arrangement space occupied by the entire device can be reduced.
The drive device 130 in the vehicle drive structure 100 of the present embodiment is used in, for example, an electronically controlled parking system. This will be specifically described below. Fig. 2 is a schematic view of the driving apparatus of fig. 1 connected to an electronically controlled parking brake unit. Referring to fig. 2, the driving structure 100 for a vehicle of the present embodiment further includes an electronically controlled parking brake unit 140. Electronically controlled parking brake unit 140 includes, for example, a control circuit that applies a braking force to disc 70 of the wheel by driving brake caliper 60 with motor 132. With this arrangement, the user does not have to laboriously operate the parking brake manually.
As described above, in the drive structure for a vehicle of the present invention, the motor is located above the reduction mechanism in the vertical direction of the vehicle. That is, the speed reduction mechanism is located below the motor. Accordingly, even if the oil of the speed reduction mechanism drops or flows downward, it does not fall to the motor. Therefore, it is possible to avoid adverse effects on the motor due to the oil of the reduction mechanism falling down to the motor.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications or substitutions do not depart from the scope of the embodiments of the present invention, and the essence of the corresponding technical solutions is not disclosed.
