Description
本發明係關於一種電動車驅動裝置，尤其是擁有雙源動力之電動車驅動裝置。The present invention relates to an electric vehicle driving device, and more particularly to an electric vehicle driving device having dual source power.
近年來，基於環保意識抬頭與全球能源危機，全世界皆投入相當大的人力與資源開發新一代之低污染、高效能的運輸工具，相較於傳統倚賴燃油引擎為動力的車輛，電動車本身不僅更具環保，而且也不需擔心與日俱增的石油短缺問題。In recent years, based on the rise of environmental awareness and the global energy crisis, the world has invested considerable manpower and resources to develop a new generation of low-pollution, high-efficiency transportation vehicles, compared to traditional fuel-powered vehicles, the electric vehicle itself. Not only is it more environmentally friendly, it also does not have to worry about the growing oil shortage.
為了使電動車同時符合車輛低速輸出高扭力以及極速的動力性能要求，若不使用變速箱，必須配備更大體積的馬達，然而由於車體足以擺放之空間有限，該大型馬達可能會使車體的空間配置受限，造成其他部件不能座落於最佳配置點；而且過大的負載或特殊的設計，也可能導致馬達與驅動器的技術等級提高，造成整體成本的負擔。In order to make the electric vehicle meet the low-speed output of the vehicle at the same time and the high-speed power performance requirements, if the gearbox is not used, a larger-sized motor must be provided. However, due to the limited space for the vehicle body to be placed, the large-sized motor may cause the vehicle. The space configuration of the body is limited, so that other components can not be located at the optimal configuration point; and the excessive load or special design may also lead to an increase in the technical level of the motor and the driver, resulting in a burden on the overall cost.
習知配用變速箱的電動車之動力系統主要包含一馬達、一變速箱、一行車控制系統及一傳動組件，該行車控制系統主要用於接收使用者下達的指令，再將該訊息傳遞至欲作動的部件，例如當使用者踩踏油門、煞車或排檔時，該指令會傳到該行車控制系統中，該行車控制系統再將該訊息傳到相對應的馬達驅動器或變速箱控制器，以改變馬達轉速或切換變速箱內的齒輪比，再將動力傳遞至傳動組件，使動力順利輸出，讓電動車隨著使用者的指令而動作。習用電動車變速箱有無段變速箱、手排變速箱、以及自動手排變速箱等。無段變速因為換檔過程之滑差，有傳動效率過低的問題。手排變速箱的傳動效率最高，但是駕駛人容易疲勞，因此，自動手排變速箱為不錯的選擇，但是，習用的自動手排變速箱的成本較高，而且因為變速箱的檔位為有限，換檔過程中所造成的扭力空洞將造成駕駛人有不舒適感。The power system of the electric vehicle equipped with the gearbox mainly comprises a motor, a gearbox, a train control system and a transmission component. The driving control system is mainly used for receiving commands issued by the user, and then transmitting the message to the The component to be actuated, such as when the user steps on the throttle, brakes, or gear, the command is transmitted to the driving control system, and the driving control system transmits the message to the corresponding motor driver or transmission controller to The motor speed is changed or the gear ratio in the gearbox is switched, and then the power is transmitted to the transmission assembly, so that the power is smoothly outputted, and the electric vehicle is operated according to the user's instruction. The conventional electric vehicle gearbox has a stepless gearbox, a handgrip gearbox, and an automatic handgrip gearbox. Stepless speed change Because of the slippage of the shifting process, there is a problem that the transmission efficiency is too low. The hand-gear transmission has the highest transmission efficiency, but the driver is prone to fatigue. Therefore, the automatic hand-gear transmission is a good choice, but the cost of the conventional automatic hand-gear transmission is high, and because the gear position of the transmission is limited. The torsion hole caused by the shifting process will cause the driver to feel uncomfortable.
再者，由於一般習知電動車之馬達的配置數量均僅為一組，該電動車於行駛時，倘若遇到該馬達損壞停擺，則該車將失去主要動力來源，無法繼以行進，導致該電動車之容錯驅動特性及可靠度不佳，讓使用者無法繼續使用或自行前往維修。Moreover, since the number of configurations of the motor of the conventional electric vehicle is generally only one set, when the electric vehicle is running, if the motor is damaged and the swing is stopped, the vehicle will lose the main power source and cannot continue to travel. The fault-tolerant drive characteristics and reliability of the electric vehicle are not good enough for the user to continue to use or to go to the repair.
本發明之主要目的係提供一種電動車之驅動裝置，該驅動裝置具有高彈性的空間配置。The main object of the present invention is to provide a driving device for an electric vehicle having a highly elastic space configuration.
本發明之次要目的係提供一種電動車之驅動裝置，該驅動裝置具有降低整體成本的特性。A secondary object of the present invention is to provide a driving device for an electric vehicle having characteristics that reduce overall cost.

該控制系統5之作動方式如第1圖所示，使用者踩踏油門時，該指令會傳送到整車控制器51，該整車控制器51可內建計算程式，根據使用者踩踏油門的深度與車速，決定並控制該變速箱3之檔位以及該二馬達1、2之動力輸出分配量，讓該二馬達1、2操作於最佳效率之操作點，然後將該資訊傳遞至二馬達驅動器11、21，由該二馬達驅動器11、21分別驅動該對應之第一馬達1與第二馬達2，使該車之總輸出功率為該二馬達1、2的輸出總合。因此，該二馬達1、2皆為該電動車之主要動力系統，透過該二馬達的聯合帶動，可順利推進設有本發明之驅動裝置的電動車。The operation mode of the control system 5 is as shown in FIG. 1. When the user steps on the throttle, the command is transmitted to the vehicle controller 51, and the vehicle controller 51 can have a built-in calculation program according to the depth of the user stepping on the throttle. And the vehicle speed, determining and controlling the gear position of the gearbox 3 and the power output distribution amount of the two motors 1, 2, allowing the two motors 1, 2 to operate at an operating point of optimum efficiency, and then transmitting the information to the two motors The drivers 11, 21 drive the corresponding first motor 1 and second motor 2 by the two motor drivers 11, 21, respectively, so that the total output power of the vehicle is the sum of the outputs of the two motors 1, 2. Therefore, the two motors 1 and 2 are the main power systems of the electric vehicle, and the electric vehicles provided with the driving device of the present invention can be smoothly advanced by the joint driving of the two motors.
該整車控制器51可透過換檔驅動器31驅動該換檔致動器32，令該換檔致動器32作動並自動換檔，使該變速箱3改變其輸出扭力，以達到該電動車同時符合低速輸出高扭力以及極速的要求，若該變速箱3如本實施例中為無離合器之自動手排變速系統時，當欲使該有限檔位之變速箱3換檔時，該整車控制器51可令第二馬達2停止動力輸出，進行電子調速功能，使變速箱3能順利換檔，同時，增加第一馬達1的輸出動力，以填補第二馬達2所需輸出的動力。The vehicle controller 51 can drive the shift actuator 32 through the shift drive 31, and the shift actuator 32 is actuated and automatically shifted, so that the gearbox 3 changes its output torque to reach the electric vehicle. At the same time, it meets the requirements of low-speed output high torque and extreme speed. If the gearbox 3 is a clutchless automatic hand shifting system in this embodiment, when the gearbox 3 of the limited gear is to be shifted, the whole vehicle The controller 51 can stop the power output of the second motor 2, perform an electronic speed control function, enable the gearbox 3 to smoothly shift, and increase the output power of the first motor 1 to fill the power required for the output of the second motor 2. .
更詳言之，當欲使該有限檔位之變速箱3換檔時，整車控制器51可令該變速箱3內之該換檔致動器32作動，推動換檔撥叉，使原有檔位的齒輪組的主動齒輪與被動齒輪脫離，並後再透過目標檔位齒輪組的同步機構，使主動齒輪與被動齒輪接合。在此一換檔過程中，該第二馬達2將停止輸出動力，並啟動電子調速功能，使該變速箱3之 目標檔位的主動齒輪與被動齒輪具有相近的轉速後才推動機械同步機構，進行入檔的動作，如此，電子同步加上機械同步機構共同發揮作用，以便能在最短的時間內在沒有習用離合器的情況下，完成平順的換檔動作，使換檔更加容易迅速。惟該換檔過程中，該第二馬達2將暫時無法為該電動車提供動力。此時，作為該電動車另一主要動力之第一馬達1會持續作動，並且根據整車控制器51的命令，適度增加輸出動力，以填補該變速箱3換檔時所造成的扭力空洞，減少駕駛人在該車的換檔過程中所產生之不舒適感。待該變速箱3內已順利切換檔位後，整車控制器51會再次分配該二馬達的動力輸出，讓該二馬達1、2操作於最佳效率之操作點。More specifically, when the gearbox 3 of the limited gear is to be shifted, the vehicle controller 51 can activate the shift actuator 32 in the gearbox 3 to push the shift fork. The driving gear of the gear set of the gear position is disengaged from the driven gear, and then the synchromesh mechanism of the target gear gear set is passed to engage the driving gear with the driven gear. During this shifting process, the second motor 2 will stop outputting power and activate the electronic speed control function to make the gearbox 3 After the driving gear of the target gear has a similar speed to the driven gear, the mechanical synchronizing mechanism is pushed to perform the shifting operation. Thus, the electronic synchronizing and the mechanical synchronizing mechanism work together so that the clutch can be used in the shortest time. In the case, the smooth shifting action is completed, making the shifting easier and faster. However, during the shifting process, the second motor 2 will temporarily be unable to power the electric vehicle. At this time, the first motor 1 which is another main power of the electric vehicle will continue to operate, and according to the command of the vehicle controller 51, the output power is moderately increased to fill the torque cavity caused by the gearbox 3 shifting. Reduce the driver's discomfort during the shifting process of the car. After the gear position has been smoothly switched in the gearbox 3, the vehicle controller 51 will again distribute the power output of the two motors to operate the two motors 1, 2 at the operating point of optimum efficiency.
請參閱第2圖所示，其係本發明之第二實施例，本實施例中另外設有一差速器6，該差速器6之一端連接於該傳動軸44，且該差速器6之另一端則供連接至另一傳動軸45，以便透過該傳動軸45結合於另一車輪，該差速器6之設置位置在此並不設限，較佳可如第二實施例中，將該差速器6與該變速箱3透過該傳動組件4互相結合，使該差速器6、變速箱3及傳動組件4之齒輪組能互相囓合牽動，以求機構配置與空間安排更為容易，使整體結構緊湊並使體積最小化。藉此，可使該第一馬達1及第二馬達2的動力同時傳送至該差速器6，並在該電動車進行轉彎時藉由該差速器6使該二傳動軸44、45可具有不同轉速，達成使車體順暢轉彎之目的。Referring to FIG. 2, which is a second embodiment of the present invention, a differential 6 is additionally provided in the embodiment. One end of the differential 6 is connected to the transmission shaft 44, and the differential 6 is provided. The other end is connected to the other drive shaft 45 so as to be coupled to the other wheel through the drive shaft 45. The position of the differential 6 is not limited thereto, and is preferably as in the second embodiment. The differential 6 and the transmission 3 are coupled to each other through the transmission assembly 4, so that the gears of the differential 6, the transmission 3 and the transmission assembly 4 can be meshed with each other, so as to achieve more arrangement and space arrangement. Easy to make the overall structure compact and minimize volume. Thereby, the power of the first motor 1 and the second motor 2 can be simultaneously transmitted to the differential 6 , and the two transmission shafts 44 and 45 can be made by the differential 6 when the electric vehicle performs a turning. With different speeds, the goal is to make the car body smoothly turn.
