201127663 VI. Description of the Invention: [Technical Field] The present invention relates to an electric vehicle, and more particularly to an electric vehicle having a plurality of gear positions. [Prior Art] Conventional electric motor vehicles can be divided into rotary drum motors according to the transmission mode.

A direct-drive electric vehicle that is a driving source and a non-direct-drive electric vehicle that is usually equipped with a speed reduction mechanism and is usually located in the center of the vehicle. The advantage of the former is that the occupied space is small (the space occupied by the transmission box is not considered), and the power loss is small, and the disadvantage is that the climbing ability is poor. Non-direct-drive electric vehicles with relatively good climbing ability can be divided into the following designs: fixed reduction ratio, two-stage centrifugal automatic transmission, and stepless speed change. The shortcoming of the above first design is that it cannot meet the high and low speed requirements; the helmet speed is better than the two-stage shift. Of course: the motor power is more effectively applied, but the transmission efficiency is poor, resulting in poor cruising ability. Moreover, it is known to be equipped with a multi-stage variable speed mechanism. The electric motor car needs to cooperate with the one-way clutch device, so that when the vehicle is pushed or pushed backwards, it will encounter considerable resistance from the motor. The improvement of this & electric vehicle design is not very ideal [invention] The main purpose of the present invention is to provide a gear type electric vehicle, 俾201127663 can solve the conventional electric vehicle climbing ability is poor, can not balance high and low speed Performance, and poor transmission efficiency. To achieve the above object, a gear type electric vehicle of the present invention includes a main power motor 'a shifting mechanism' and a shifting mechanism. The shifting mechanism includes an input shaft, an output shaft, a plurality of input shaft gears, and a plurality of output shaft gears, wherein the plurality of input shaft gears mesh with the plurality of output shaft gears to form a plurality of slots. The shifting mechanism includes a shifting drum and a myocardium. Set the number: Μ ° and shifting 豉, and according to the rotation of the shifting drum, the displacement and drive corresponding: the gear of the shifting mechanism is engaged or not engaged with the adjacent gear, so that the shaft is divided into multiple buildings. - Pass power to the output shaft. In addition, only one single gear position is established during the same day, and when the multiple gears and corresponding gears are not stuck, the input shaft does not transmit power to the output shaft when it is adjacent to the gear, which is: slot 0 - by the above mechanism Design, high and low speed performance of electric vehicles

i empty == drought improvement, but also better. The § § ́ rider can easily push the vehicle forward and backward. Gear = one fork is available =: the first fork is connected to a plurality of power outputs. The one fork is connected to the plurality of input shaft gears. The plurality of wheel axle gears may include a wheel and a second input shaft gear. The input shaft is occluded into the shaft gear, the plurality of gears, and the fourth corresponding meshing first input _ the output shaft is the first output shaft gear corresponding to the name 4 201127663 two input shaft gears, the third output shaft gear corresponding to the third spray The input shaft gear and a fourth output shaft gear are correspondingly engaged with the fourth input shaft gear. The output shaft gear is coupled to the first fork and synchronously rotated relative to the output shaft and: slidable; the third input shaft gear is coupled to the second dial and rotates synchronously with respect to the input shaft and is axially slidable. The first input shaft gear rotates synchronously with respect to the input two; the fourth output shaft gear rotates synchronously with respect to the output shaft; the second input shaft gear and the fourth input (four) wheel are both non-synchronous with respect to the input shaft, and the output shaft Both the gear and the second output shaft gear are synchronously rotated with respect to the output shaft non-speed drum. The shifting mechanism disc change mechanism can be located in the - box body, and the main power motor and the shift motor are all fixed to the box body. This type of body configuration can effectively benefit the speed tank space. The main power motor, or the slot motor, can be electrically connected to an electronic component and controlled by it. Next to the shifting drum, there may be (4) a residual sensor system (4) connected to the electronic control unit to transmit the gear position information as the basis for electronic control. Erping

An output sprocket can be coaxially attached to the output shaft to transmit rotational power to the wheel through the chain transmission. A beak can be set beside the fork, and a pre-force is applied to the shifting mechanism to enable the shifting mechanism to safely perform the shifting action. [Embodiment] ^ Reference FIG. ' is a block diagram of a motor vehicle power and transmission system. The actual example is - electric motor car, its power and transmission system architecture includes - electronic # system unit 2 - main power Ma Xian, - shifting mechanism τ, - changing mechanism ^ 201127663 a shifting motor 18, a chain gear set p, and one wheel %. The electronic control unit 21 is electrically connected and controls the main power motor 丨丨 and the shift motor 丨8, the main power motor 11 is coupled to the shifting mechanism Τ, the shifting motor 18 is coupled to the shifting mechanism G, and the shifting mechanism is coupled to the chain gear The set ρ, the chain gear set ρ is coupled to the wheel W, wherein the chain gear set ρ includes a sprocket 17 (shown in Figure 2) and a chain (not shown) spanning the sprocket 17. The shifting mechanism G functions to establish one of the plurality of shifting modes G of the shifting mechanism G, so that the shifting mechanism T can transmit the motor power according to the established specific gear position. The shifting mechanism and the shifting mechanism <3 are all located in a casing (7), and the main power motor 11 and the shifting motor 18 are fixed to the casing 1 to be a one-piece device, so that the utilization of the narrow space is more efficient. Referring to Figures 2 and 3', there is a side view of the electric motor vehicle and its cross-sectional circle. In detail, the shifting mechanism τ includes an input shaft 2, an output shaft 13, four input shaft gears 121 to 124, and four output shaft wheels 131 to 13 and a main power motor 11 coupled to the input shaft 12 The power is directly transmitted, and the coaxial sprocket 17 of the coaxial sleeve is output on the output shaft B. The four input shaft gears 121 to 124 and the four output shaft gears 131 to 134 are mutually corresponding and combined to form four gear ratios, that is, the four (four) position mode is that the four (four) position shift mode is still required to pass through the shifting machine" In order to truly establish the ability to transmit the dynamic mechanism, when it fails to establish the available position, it is in the second place: the neutral mode that can transmit power. The unsuccessful idea is that the input shaft/output The gears of the shaft with respect to the input shaft/output shaft η must be rotated by the stepping shaft, and the other is the asynchronous rotation 201127663 (ie, freely rotating). The input vehicle is also coupled with the gears on the output shaft. It must be synchronously rotated with respect to the axis to which it is attached, and the other is non-synchronous. The shifting mechanism G includes a shifting drum 14', a shifting shaft 20, and two dials 15, 16, and the shifting drum 14 is coupled to one. The shifting motor 18 is driven by the shifting motor 18. The two dials 15, 16 are respectively slidably disposed on the shifting drum 14 with their ends embedded in the sliding grooves 141, 142 of the shifting drum, and are supported by the shifting fork shaft 20. 14 rotation, two dials 15, and 16 will be driven in the chutes 141, 142 to produce displacement.

The first input shaft gear 121 , the second input shaft gear 122 , the third wheel input shaft gear 123 , and the fourth input shaft gear 124 are sequentially disposed on the input shaft 12 , and the first input shaft gear 121 is opposite to the input shaft 12 . Synchronously rotating, the second input shaft gear 122 and the fourth input shaft teeth 124 are all asynchronously rotated with respect to the input shaft 12, and the third input shaft gear 123 is coupled to the second shift fork 16 and rotates synchronously with respect to the input shaft 12 and Axial slidable. The first output shaft gear 131, a second output shaft gear 132, a third output shaft gear 133, and the fourth output shaft gear 134 are sequentially disposed on the output shaft 13, the first output shaft gear 131 and the third output shaft. The gears 133 are all asynchronously rotated with respect to the output shaft 13, and the second output shaft gear 132 is coupled to the first shifting fork 15 and is synchronously rotatable with respect to the output shaft 13 and axially slidable, and the fourth output shaft gear 134 is opposite to the output. The shaft 13 is in synchronous rotation. The shifting operation process of the electric vehicle of the present invention will be described below. The beginning of the shifting drum (four) Μ zero Μ 'In this state, the position of the first _ dial and 15 is the same, the connected: the output shaft gear 132 does not lightly match the adjacent first output shaft gear 131 and the third round output shaft The teeth are arranged such that the 16-position input shaft gear 丨 23 is not coupled to the adjacent 201127663 second input shaft gear 122 and the fourth input shaft gear 124. At this time, the power cannot be transmitted from the input shaft 12 to the output shaft 13, and is empty. When the shift motor 18 drives the shift drum 14 to rotate to a first angle, the first dial 15 is moved to couple the second output shaft gear 132 to which it is coupled to the adjacent first output shaft gear 131'. The dial 16 is moved so that the third input shaft gear 123 to which it is connected is not coupled to the positions of the adjacent second input shaft gear 122 and the fourth input shaft gear 124. In other words, it must be the same: time only single-clamping is established. Therefore, in the design of multiple dials, only one gear can be coupled to perform the coupling action. At this time, the power transmission path is the first input shaft gear 121, the output shaft gear m, the second output shaft gear 132, and the output (4), which are the first type of position. The shifting motor 18 drives the shifting drum 14 to rotate to a second angle, and the shifting (10) is moved to the second output shaft gear 132 to which it is coupled to the third output shaft gear 133 adjacent to the first output shaft gear 133, The two input shaft gears 123 are not constrained to the position of the adjacent second input shaft gear 122 and the fourth input shaft gear 124. At this time, the power transmission path is sequentially the third input (four) wheel 123, the third output shaft gear (1), and the second output shaft gear 132. When the two shifting motors 18 drive the shifting drum 14 to rotate to the third angle, and the second:: again! 5 moves to the second round of the shaft gear 132 to which it is connected. - The output shaft gear 131 and the third output shaft gear (1) are moved to a position where the H-axis gear 123 201127663 connected thereto is engaged with the adjacent second input shaft gear 122. At this time, the 'power transmission path is the third input wheel gear 123, the second input shaft gear 122, and the second output shaft gear 132'. , is the third gear. When the shift motor 18 drives the drum 14 to rotate to the fourth angle and the first fork 15 is still located such that the second output shaft gear 132 to which it is connected does not engage the adjacent first-output shaft gear 131 With the third round shaft gear 133, the second shift fork 16 is moved to a position where the third input shaft gear 123 to which it is coupled faces the adjacent fourth input shaft gear 124. At this time, the power transmission path is the third input shaft gear 123, the fourth input shaft gear 124, the fourth output shaft gear 134, and the output shaft 13 in the order of the fourth gear position. In the case where the shifting mechanism G is driven by a motor, the advantage of cooperating with the electronic control unit (ECU) 21 is that an automatic shifting function can be obtained. For example, when the electric vehicle wants to be upgraded to a higher speed gear position at a certain gear speed, the ECU 21 first controls the main power motor u to slow down, then controls the shift motor 18 to switch the gear position, and finally the main power motor 丨The speed is increased back, which also makes the shifting process smooth. : In addition to being driven by a motor, the shifting mechanism can of course be designed as a manual using a linkage mechanism. It can be seen from the above that the electric vehicle of the present invention can obtain the amplified torque only by the small motor driving source, and also has the multi-stage gear shifting characteristic, and pushes forward or backward by manpower because it does not need to be equipped with the one-way clutch device. When the vehicle is assisted, it will not encounter the considerable 201127663 impedance force from the motor as long as the gear is switched to neutral. In addition, the shifting drum u is provided with a play position sensor 19 which rotates the phase to obtain the clamp information. Each set of 15, 16 side planting ^ a ridge 22, 23 to give a pre-force 'can ensure that the change of the agency G safely change the floor action. The above-described embodiments are merely examples for the convenience of the description, and the scope of the claims is intended to be limited to the above-mentioned embodiments.
