The floor 22 extends in the front-rear direction (arrow a direction) of the electric vehicle 10. The front wheel 24F is rotatably supported on the front portion of the frame 17 of the vehicle body 16 by a front suspension device not shown. The rear wheel 24R is rotatably supported on the rear portion of the frame 17 on the vehicle body 16. The floor 22 is disposed substantially parallel to the road surface G (ground surface) on which the front wheels 24F and the rear wheels 24R are in contact. As shown in fig. 2, the frame 17 has a1 st cross member 171 and a2 nd cross member 172 extending in the vehicle width direction. The 1 st cross member 171 is disposed between the pair of rear wheels 24R. The 2 nd beam 172 is disposed forward of the 1 st beam 171.
As shown in fig. 2, the drive unit 14 has, for example, a motor 26 and a reduction gear. The motor 26 is a motor rotated by electric power, for example. The drive unit 14 is arranged via the support structure 20 in the region of the rear end 221 of the base plate 22. The drive unit 14 drives the rear wheel 24R. The drive unit 14 is disposed at a substantially central portion in the vehicle width direction (the direction of arrow B) at a rear end 221 of the floor 22. The driving unit 14 is disposed forward of the rear end 161 of the vehicle body 16 (floor 22). The drive unit 14 is disposed between a pair of rear wheels 24R. As shown in fig. 3, the drive unit 14 is disposed so as to protrude downward from the floor 22 in the vehicle height direction (arrow C direction) of the electric vehicle 10. In addition, a driving unit for driving the front wheels 24F may be provided at the front portion of the frame 17 independently of the driving unit 14 for driving the rear wheels 24R.
As shown in fig. 2, the drive unit 14 has a housing 28 with a built-in motor 26 and a reduction gear. The motor 26 is rotatable within the housing 28 by electrical power. The rotation shaft 30 is mounted to the rotation center of the reduction gear. The rotation shaft 30 of the drive unit 14 extends to both sides in the vehicle width direction with respect to the case 28. The rotation shaft 30 is rotated via a reduction gear by driving the motor 26. Further, the drive unit 14 is not limited to a structure having the motor 26 and the reduction gear. The drive unit 14 may be constituted by only the motor 26.
A pair of drive shafts 34 are connected to the ends of the rotation shaft 30 via joints 32. The pair of drive shafts 34 are arranged along the vehicle width direction (arrow B direction) of the vehicle body 16. The rotary shaft 30 and the rear wheel 24R are connected to each other via a drive shaft 34.
The suspension device 18 includes: a pair of trailing arms 361, 362, a torsion beam 38 connecting the pair of trailing arms 361, 362 to each other, and a damper 40 and a spring 42 held by the trailing arms 361, 362.
The pair of trailing arms 361, 362 extend along the front-rear direction (arrow a direction) of the vehicle body 16, and are disposed apart from each other in the vehicle width direction (arrow B direction) of the vehicle body 16. The pair of trailing arms 361 and 362 are disposed on the vehicle width direction inner side with respect to the rear wheel 24R. The distal ends of the pair of trailing arms 361, 362 are supported by the 2 nd cross member 172 of the vehicle body 16 so as to be swingable with respect to the 2 nd cross member 172 of the vehicle body 16. The rear wheel 24R is supported at the rear of the pair of trailing arms 361, 362 in the front-rear direction of the vehicle body 16. By pivoting the front ends of the trailing arms 361 and 362, the rear end sides of the trailing arms 361 and 362 swing in the direction approaching or separating from the floor 22, and the rear wheels 24R are supported swingably in the up-down direction by the trailing arms 361 and 362.
The trailing arms 361, 362 have the damper receiving portion 44 and the spring receiving portion 46. The damper receiving portion 44 is provided at the rear ends of the trailing arms 361 and 362. The damper 40 is held between the damper receiving portion 44 and the vehicle body 16. The damper 40 is disposed substantially orthogonal to the bottom plate 22 (see fig. 4). The spring receiving portion 46 extends inward in the vehicle width direction from substantially the center of the trailing arms 361, 362. The spring 42 is held between the spring receiving portion 46 and the vehicle body 16. The spring 42 is, for example, a coil spring. The spring force of the spring 42 acts in a direction (vehicle height direction) substantially orthogonal to the bottom plate 22.
During running of the electric vehicle 10, the load input from the road surface G to the rear wheels 24R is absorbed by the springs 42 and damped by the shock absorbers 40.
As shown in fig. 2, the torsion beam 38 is disposed along the vehicle width direction (arrow B direction) of the vehicle body 16. The torsion beam 38 is disposed forward of the drive unit 14. That is, the driving unit 14 is disposed rearward with respect to the torsion beam 38. The torsion beam 38 is disposed rearward of the front ends of the trailing arms 361, 362.
The torsion beam 38 has a pair of connecting portions 481, 482 connected to the trailing arms 361, 362 at both ends thereof. When viewed from the front of the vehicle body 16 shown in fig. 4, the connection portions 481, 482 are arranged at substantially the same height as the central axis of the rear wheel 24R in the vehicle height direction. The height of the connection parts 481 and 482 is not limited to the case of being disposed at substantially the same height as the central axis of the rear wheel 24R. As shown in fig. 2, the torsion beam 38 is connected to the trailing arms 361, 362 at a position rearward relative to the front ends of the trailing arms 361, 362. The connection portions 481, 482 of the torsion beam 38 are attached to the trailing arms 361, 362 from below and fixed by welding or the like. When the pair of trailing arms 361, 362 swings together with the rear wheels 24R during running of the electric vehicle 10, the torsion beam 38 swings with the trailing arms 361, 362.
As shown in fig. 4, the torsion beam 38 has a cross portion 50, and the cross portion 50 is curved in a convex shape upward when viewed from the front of the vehicle body 16. The intersecting portion 50 is provided at a substantially central portion in the extending direction of the torsion beam 38, which is the vehicle width direction of the vehicle body 16. The intersecting portion 50 gradually and gradually bends upward from the pair of connecting portions 481, 482 toward the center in the extending direction. The torsion beam 38 including the intersecting portion 50 is formed in a substantially circular arc shape. The upper surface 501 of the intersecting portion 50 is curved convexly upward so as to face the bottom plate 22. The lower surface 502 of the intersecting portion 50 is concavely curved upward to be recessed. The upper portion of the crossing portion 50 is separated from the floor panel 22 in the vehicle height direction.
As shown in fig. 2, the support structure 20 has a plurality of support members 52. The plurality of support members 52 have a front support member 54 and a rear support member 56.
The front support member 54 is disposed forward of the drive unit 14 in the front-rear direction of the vehicle body 16. The front support member 54 is formed in a plate shape whose plate thickness direction is the vehicle width direction of the vehicle body 16. The front support member 54 extends linearly from the drive unit 14 toward the front of the vehicle body 16. That is, the front support member 54 is formed linearly along the front-rear direction (the arrow a direction) when the vehicle body 16 shown in fig. 2 is viewed in plan. As shown in fig. 3, the rear end 541R of the front support member 54 is connected to the front end of the housing 28 on the drive unit 14 by a bolt 58. The width H of the front support member 54 in the vehicle height direction decreases as going forward from the drive unit 14. The width H of the front support member 54 in the vehicle height direction is largest at the rear end 541R of the front support member 54.
As shown in fig. 2, the width W1 of the front support member 54 is smaller than the width W2 of the drive unit 14 (the width of the case 28) in the vehicle width direction of the vehicle body 16 (W1 < W2). The front support member 54 is disposed and connected in a width region between one end 281 in the width direction and the other end 282 in the width direction of the housing 28 of the drive unit 14 in the vehicle width direction (arrow B direction) of the vehicle body 16.
As shown in fig. 2, the front support member 54 intersects with the intersection 50 of the torsion beam 38 when viewed from a plan view in a vehicle height direction orthogonal to the front-rear direction of the vehicle body 16 and orthogonal to the vehicle width direction. As shown in fig. 4, the intersection 50 is curved upward with respect to the front support member 54 and separated when viewed from the front of the vehicle body 16. The front support member 54 is separated from the intersection 50 in the vehicle height direction.
As shown in fig. 2, the front end 541F of the front support member 54 is fixed to the vehicle body 16 forward of the torsion beam 38. The front end 541F of the front support member 54 is supported by the bracket member 60 provided on the lower surface of the 2 nd cross member 172. The front end 541F of the front support member 54 is inserted into the center portion of the elastic member 62 in the bracket member 60 and held. The vibration of the front end 541F of the front support member 54 is absorbed and relaxed by the elastic member 62.
The rear support member 56 is disposed rearward of the drive unit 14 in the front-rear direction (arrow a direction) of the vehicle body 16. The rear support member 56 is disposed between a rear end 161 of the vehicle body 16 (floor 22) and the drive unit 14.
The rear support member 56 has: the lever member 64, a connecting member 66 connecting the lever member 64 and the driving unit 14, and a plurality of fixing portions 68 provided at both end portions of the lever member 64. The lever member 64 is formed in an axial shape and is disposed along the vehicle width direction (arrow B direction) of the vehicle body 16. The lever member 64 is disposed substantially parallel to the rotation shaft 30 of the drive unit 14. The length of the lever member 64 in the vehicle width direction is longer than the width W2 of the drive unit 14 (the width of the case 28). Further, the length of the lever member 64 is not limited to the case of being longer than the width W2 of the driving unit 14.
The connecting member 66 is connected to a longitudinal center portion of the lever member 64. The connecting member 66 extends forward relative to the lever member 64. As shown in fig. 3, the connection member 66 is connected to the rear end of the housing 28 of the drive unit 14 via a bolt 70. The fastening direction of the bolts 70 is the vehicle width direction of the vehicle body 16. Accordingly, the lever member 64 of the rear support member 56 is connected to the rear end of the drive unit 14. The fastening direction of the connecting member 66 is not limited to the vehicle width direction of the vehicle body 16. The connection member 66 may also be fastened to the rear end of the driving unit 14 in the front-rear direction.
The plurality of fixing portions 68 fix the lever member 64 to the floor 22 of the vehicle body 16. The plurality of fixing portions 68 are, for example, a pair of fixing portions 681 and 682 disposed at both end portions of the lever member 64. Next, a case where the rear support member 56 has a pair of fixing portions 681, 682 will be described. The pair of fixing portions 681, 682 are separated in the longitudinal direction (arrow B direction) of the lever member 64 through the lever member 64. The pair of fixing portions 681 and 682 are fixed by the fastening member 74 in a state of abutting against the mounting portion 72 provided on the lower surface 223 of the bottom plate 22. The fixing direction of the fixing portions 681, 682 is the up-down direction (arrow C direction) orthogonal to the extending direction (arrow B direction) of the lever member 64. The fixing portions 681, 682 are fixed toward the bottom plate 22 by the fastening member 74.
The present embodiment has the following effects.
As shown in fig. 2, the electric vehicle 10 has a vehicle body 16, a drive unit 14, a suspension device 18, and a support structure 20, wherein the drive unit 14 is mounted to the vehicle body 16 and has an electric motor 26 driven by electric power; the suspension device 18 connects a pair of trailing arms 361, 362 supported by the vehicle body 16 and separated in the vehicle width direction of the vehicle body 16 to each other by a torsion beam 38 extending in the vehicle width direction; the support structure 20 supports the drive unit 14 to the vehicle body 16. The drive unit 14 is disposed rearward of the torsion beam 38, and the support structure 20 has a front support member 54, and the front support member 54 is disposed forward of the drive unit 14 in the front-rear direction (arrow a direction) of the vehicle body 16. The front support member 54 has a width W1 smaller than the width W2 of the drive unit 14 in the vehicle width direction (arrow B direction) of the vehicle body 16. The front support member 54 extends from the drive unit 14 toward the front of the vehicle body 16, intersects the torsion beam 38, and is fixed to the vehicle body 16 on the front side with respect to the torsion beam 38.
According to this structure, when the electric vehicle 10 is traveling, the load in the front-rear direction generated by the drive unit 14 at the time of acceleration and deceleration of the vehicle can be effectively received by the front support member 54. Therefore, the support structure 20 receiving the load in the front-rear direction can be simplified and reduced in weight compared to a structure using a front support member having a width W2 larger than the driving unit 14. Accordingly, the manufacturing cost of the electric vehicle 10 can be reduced.
The front support member 54 is disposed in a width region between one end 281 and the other end 282 of the drive unit 14 (the case 28) in the vehicle width direction, and therefore, in the vehicle width direction of the vehicle body 16, a position close to the center of gravity of the drive unit 14 can be supported by the front support member 54. Accordingly, the load generated when the electric vehicle 10 travels can be effectively alleviated by the front support member 54.
The torsion beam 38 has a crossing portion 50 crossing the front support member 54 in a plan view from a vehicle height direction orthogonal to the front-rear direction of the vehicle body 16 and to the vehicle width direction, and as shown in fig. 4, the crossing portion 50 is separated from the front support member 54 and is formed to be convexly curved upward.
According to this structure, by bending the intersection 50 of the torsion beam 38 upward, the front support member 54 and the torsion beam 38 can be effectively intersected in a plan view. Accordingly, the support structure 20 can be compactly constructed, and the installation space of the vehicle body 16 can be effectively used. By bending the torsion beam 38 upward, the roll center at the time of rolling the vehicle body 16 can be increased, and the steering stability can be improved.
The support structure 20 includes a rear support member 56 disposed rearward of the drive unit 14, and the rear support member 56 includes a plurality of fixing portions 681 and 682 for fixing to the vehicle body 16, and is fixed to the vehicle body 16 by the plurality of fixing portions 681 and 682. According to this structure, when a large load is generated at the time of acceleration and deceleration of the electric vehicle 10 due to the driving torque of the driving unit 14, the load acting in the vehicle width direction (left-right direction) can be received by the rear support member 56 fixed by the plurality of fixing portions 681, 682, and the load can be effectively relaxed. Since the mounting pitch P between the fixed point of the front support member 54 to the vehicle body 16 and the fixed point of the rear support member 56 to the vehicle body 16 can be ensured in the front-rear direction of the vehicle body 16, a large load due to the driving torque of the driving unit 14 can be effectively alleviated. When the electric vehicle 10 accelerates, noise and vibration of the drive unit 14 can be suppressed from being transmitted to the vehicle body 16.
As shown in fig. 3, the width H of the front support member 54 in the vehicle height direction decreases as it goes forward from the drive unit 14. According to this structure, the drive unit 14 can be supported more reliably by extending the front support member 54 in the front-rear direction of the vehicle body 16. Therefore, the front support member 54 can have sufficient load-bearing performance. Since the width H in the vehicle height direction of the front side of the front support member 54 can be reduced, the support structure 20 can be made lightweight and compact.
As shown in fig. 2, the front support member 54 is formed linearly in the front-rear direction when the vehicle body 16 is viewed in plan, and therefore, the front support member 54 is easy to form, and the manufacturing cost can be reduced and the workability of assembly can be improved. The load in the front-rear direction generated in the drive unit 14 at the time of acceleration and deceleration of the vehicle can be more effectively received by the front support member 54.
The front support member 54 is formed in a plate shape, and the plate thickness direction of the front support member 54 is the vehicle width direction of the vehicle body 16. Accordingly, the front support member 54 can be realized at low cost.
