Definitions
- the present invention relates to an electric motorcycle using an electric motor as a drive source, an ATV (All Terrain Vehicle), and a saddle-type electric vehicle including a hybrid type equipped with an engine.
- the present invention relates to the layout of motors and power storage devices.
- the energy density of the secondary battery is still an order of magnitude lower than that of petroleum-based fuels such as gasoline, and a plurality of batteries must be installed to ensure a practical travel distance.
- a straddle-type vehicle such as a motorcycle originally has no space, so it is necessary to devise how to mount a plurality of batteries on the vehicle body.
- a large number of battery cells are arranged in a large battery box arranged so as to be surrounded by a main frame, a down frame and a pivot frame of a vehicle body. Arranged. Since the scooter type electric motorcycle generally has a low output and the electric motor can be small, an in-wheel type electric motor provided integrally with the rear axle is adopted in this type.
- the electric motorcycle described in the same document has a large energy storage disposed close to the upper side of the electric motor as shown in FIG. ing.
- This energy storage is a power storage device in which a large number of batteries are housed in a housing. According to FIG. 2, the energy storage is located behind the electric motor from the rear.
- Patent Document 1 In the scooter type electric motorcycle as in the former conventional example (Patent Document 1), since the mounting position of the heavy battery is low, the handling is easy, but the motor performance is not so high. I can not say.
- Patent Document 2 since a heavy power storage device is mounted above the electric motor, the position of the center of gravity is too high, and it may be difficult to handle.
- the center of gravity of the power storage device at a relatively high position is behind the electric motor at a relatively low position. Since they are lined up, there remains room for the positions of the centers of gravity to be further brought closer to the above-described forwardly rising roll axis.
- the object of the present invention is to devise the layout of the electric motor and the power storage device, both of which are heavy items, while making the center of gravity of each of them closer to the roll axis while appropriately reducing the combined center of gravity of both. It is to improve the balance between good handling and athletic performance.
- the present invention is directed to a straddle-type electric vehicle in which a traveling electric motor is mounted between a front wheel and a rear wheel, and the rear wheel is driven via a power transmission mechanism.
- the power transmission mechanism is disposed in parallel to the motor shaft behind the motor shaft of the electric motor, transmits rotation from the motor shaft, and transmits the rear via a transmission member extending rearward.
- An output shaft for transmitting rotation to the wheel is provided, and the shaft center of the motor shaft is lower than the shaft center of the output shaft.
- the height of the output shaft of the power transmission mechanism is generally determined from the requirements on the vehicle body side.
- a chain or belt endless transmission member
- the height of the output shaft is almost the same as the pivot shaft that supports the front end of the swing arm. It must be the same (or slightly higher).
- the axis of the electric motor on the drive side is generally the same height with respect to the output shaft.
- the axis of the electric motor lower than the output shaft, in other words, by making the mounting position of the electric motor on the vehicle body as low as possible, it is easy to secure the space for arranging the power storage device above the electric motor.
- the position of the electric motor relatively forward is lowered, so that the power storage device can be mounted from the upper side of the power plant to the diagonally front.
- the center of gravity of the power storage device at a higher position is closer to the front than the center of gravity of the power plant at a relatively lower position.
- the roll axis generally extends from the ground contact point of the rear wheel to the upper end and the lower end of the head pipe as viewed from the side of the vehicle body. Is defined within the area between. Therefore, the center of gravity of the power storage device may be positioned in the roll axis area, while the center of gravity of the power plant may be positioned below the lower boundary line of the roll axis area. If it carries out like this, the synthetic gravity center of a power plant and an electrical storage apparatus will become the suitable height of the downward direction of a roll axis.
- the pivot support portion It is good also as a structure which supports a power plant adjacent to the front side. This also makes the center of gravity of the power plant approach the roll axis.
- an input shaft that is arranged in parallel to both the shafts behind the motor shaft of the electric motor and in front of the output shaft with respect to the output shaft is transmitted. It is good also as a gear-type transmission which changes the rotation from the motor shaft transmitted to the said input shaft, and transmits it to the said output shaft by the gear train provided in the said input shaft and the said output shaft, respectively.
- Such a gear-type transmission can be compactly configured with a space between the input shaft and the output shaft. Furthermore, if the driven gear on the input shaft that meshes with the drive gear on the motor shaft is partially overlapped with the electric motor in a side view of the vehicle body, and the layout is such that the input shaft is as close to the motor shaft as possible, The distance between the transmission and the electric motor is also reduced. If the power plant as a whole is miniaturized in this way, the position of the electric motor that is relatively forward in the power plant approaches the rear pivot support, and this also causes the center of gravity of the power plant to approach the roll axis. It will be.
- the vehicle body frame includes a main frame portion extending rearward from the head pipe and a pair of left and right down frame portions extending downward from the front end portion of the main frame portion, at least one of the left and right down frame portions.
- the lower part may be positioned on the outer side in the vehicle width direction than the power storage device.
- the power storage device is less likely to receive a direct impact from the road surface. If projections are provided on the upper portions of the left and right down frame portions so as to project outward in the vehicle width direction from the power storage device, it is further difficult to receive an impact from the road surface.
- the torsional rigidity of the vehicle body frame can be integrally secured by the central main frame portion and the pair of left and right down frame portions.
- the main frame part itself may be composed of a frame member divided into left and right, and the power storage device may be mounted so as to be surrounded by this. Also in this case, the impact applied to the power storage device when the vehicle rolls over can be reduced.
- the straddle-type electric vehicle mounts a power plant composed of an electric motor and a power transmission mechanism as close as possible to the center of the vehicle body in a state of lowering the front, so that the power storage device is mounted obliquely forward from above.
- a power plant composed of an electric motor and a power transmission mechanism as close as possible to the center of the vehicle body in a state of lowering the front, so that the power storage device is mounted obliquely forward from above.

Abstract
Description
図1は、本発明の第1の実施形態に係る電動二輪車1(電動車両)の主に車体フレームやパワープラント、車輪等の主要部について示す右側面図であり、図2は、同様にして前方から見た正面図である。図1に示すように電動二輪車1は、操舵輪である前輪2と駆動輪である後輪3とを備えている。前輪2は、各々略上下方向に延びる左右一対のフロントフォーク4の下端部に回転自在に支持されており、一方、フロントフォーク4の上部は上下一対のブラケット4aを介してステアリング軸(図示せず)に支持されている。
次に、図1及び図4を参照して、本実施形態の電動二輪車1における走行用モータ20(パワープラント40)やバッテリ50のレイアウトについて詳しく説明する。まず、一般的に二輪車のように車体が傾動するものでは、その重心位置が高くなると取り回しが容易ではなくなる一方で、重心位置が低すぎると旋回時の軽快感が損なわれる。すなわち、二輪車は旋回しながら傾動するので、車体の動的な旋回中心線(ロール軸線)は水平にはならず、後輪の接地点から前方斜め上方に向かうように規定される。そして、このロール軸線から重心位置が離れるほど車体の旋回時の慣性モーメントが大きくなってしまうからである。
図5には変速装置の構造を簡略化した変形例を示す。この変形例の変速装置130において歯車列135は、前記実施形態の歯車列35に比べて歯車の数が少なく、例えば2段階に変速するものである。こうして歯車の数が少ない分、クラッチシャフト31や出力シャフト34の長さを短縮して、パワープラント140の寸法及び重量を削減することができる。但し、スプロケット36の位置は後輪3のスプロケットの位置に対応して決まるので、図示のように後輪3の、即ち車体の中心線C(一点鎖線で示す)よりも左側が重くなってしまう。これについては、図示は省略するが、例えばバッテリ50を右側が重くなるように左右非対称に配置したり、或いは走行用モータ20の重心を車体中心線Cの右側に配置したりすればよい。
図6、7には、本発明の第2の実施形態に係る電動二輪車101を示す。両図はそれぞれ上述した第1実施形態の図1、2に相当する。なお、この第2実施形態の電動二輪車101は、車体フレームやパワープラントの構造が第1の実施形態とは異なっており、これに伴いバッテリ51(蓄電装置)の搭載の仕方も異なっている。以下では、その異なる部分を説明し、同一の部材には同一の符号を付してその説明は省略する。
上述した第1及び第2の実施形態の説明は例示に過ぎず、本発明、その適用物又はその用途を制限するものではない。例えば第1の実施形態では蓄電装置であるバッテリ50を、左右2個ずつ搭載しており、第2の実施形態ではバッテリ51を左右4個ずつ搭載しているが、バッテリ50,51の個数は左右同数でなくてもよい。
