Embodiment 1

[0027] see figure 1 , present embodiment 1 is suitable for the combined transmission of automobiles and locomotives driven by electric power, including a bracket 4 supporting the output shaft 2 of the motor 1, a driving gear 3 mounted on the output shaft of the motor in the bracket, and the axis of the bracket is parallel to the axis of the output shaft of the motor The rear end stretches out the active magnetic induction body shaft 6 outside the bracket, the driven gear 5 which is mounted on the active magnetic induction body shaft in the bracket and meshes with the driving gear, and has a layer of magnetic induction coil mounted on the active magnetic induction body shaft 7-1 The active magnetic induction body 7, the first end coaxial with the axis of the active magnetic induction body is supported in the active magnetic induction body and the second end is supported on the dial 11 driven by the servo motor (or hydraulic pressure) The driven permanent magnet coil shaft 9, th...

Embodiment 2

[0037] see figure 2 , present embodiment 2 is basically the same as embodiment 1, and the difference is that the gear ratio of the driving gear and the driven gear is 1:2.5, the magnetic induction coil on the active magnetic induction body is two layers, and the inner and outer rings of the driven permanent magnetic coil Permanent magnets 12 are all housed on the outer walls. The transmission realizes a small body position and a large torsion energy. It adopts Changan Yidong EV, pure electric vehicle, permanent magnet synchronous motor, maximum power of 90KW, maximum torque of 280NM, vehicle weight of 1610Kg, cruising range of 200Km, and maximum speed of 140Km per hour.

[0038] With this transmission scheme:

[0039]For the design of fuel vehicles, as long as the quality of the vehicle, the required power, the torque required for starting (hill start), sufficient traction and top speed can be matched, the corresponding power and transmission can be matched. The tonnage st...

Embodiment 3

[0046] see figure 2 , the present embodiment 3 is basically the same as embodiment 2, the difference is that the gear ratio of the driving gear and the driven gear is 1:2.5, and the heavy-duty truck is calculated with this transmission.

[0047] The fuel heavy truck is 290, with a total loading mass of 14 tons. Currently installed is a 290 hp diesel engine. Equivalent to 217KW. Torque of 420NM.

[0048] A 115KW permanent magnet motor is used, with a peak torque of 850NM, a speed of 2500-4500 and this transmission (the transmission is equipped with a fixed permanent magnet brake ring) to form a truck transmission. Gear ratio 1:2.5, fork speed 1:3.7. The diameter of the tire is 1.10m. The calculation is as follows: the car is changed to electricity. Calculated according to the motor parameters and the design parameters of the transmission, the modified truck torque is 2125NM. It is 1.37 times the torque of the first gear of the fuel vehicle, and the load is 2125÷130=16.0...

Abstract

The invention discloses an automobile and locomotive combined transmission suitable for electric power pushing. The combined transmission comprises a support, a driving gear, a driving magnetic induction body shaft, a driven gear, a driving magnetic induction body, a driven permanent magnet ring shaft and a driven permanent magnet ring, wherein the support is used for supporting an output shaft ofa motor, the driving gear is located in the support and arranged on the output shaft of the motor, the driving magnetic induction body shaft is arranged on the support, the axis of the driving magnetic induction body shaft is parallel to the axis of the output shaft of the motor, furthermore, the rear end of the driving magnetic induction body shaft extends out of the support, the driven gear islocated in the support, arranged on the driving magnetic induction body shaft and is meshed with the driving gear, the driving magnetic induction body is arranged on the driving magnetic induction body shaft and provided with at least one layer of magnetic induction ring, the driven permanent magnet ring shaft is coaxial to the driving magnetic induction body shaft, the first end of the driven permanent magnet ring shaft is supported in the driving magnetic induction body, furthermore, the second end of the driven permanent magnet ring shaft is supported on a driving disc, the driven permanentmagnet ring is arranged on the driven permanent magnet ring shaft and cooperates with the magnetic induction rings on the driving magnetic induction body to sleeve the driven permanent magnet ring shaft or exit, and the gear ratio of the driving gear to the driven gear is 1:1-6. According to the automobile and locomotive combined transmission suitable for electric power pushing, the effects of speed change, torque increase, being energy-saving, being good in stability and being safe are achieved.

Description

Technical field: [0001] The invention relates to a transmission, in particular to a combined transmission suitable for electric vehicles, locomotives and the like. Background technique: [0002] The structures of power transmission devices of automobiles and locomotives currently in use are summarized as follows: [0003] 1. Motor + clutch + gear transmission + fork speed + tire. [0004] 2. Motor + reducer + fork speed + tires. [0005] 3. Motor + reducer + tire. [0006] The above-mentioned first two structures are complicated. The latter consumes energy, has poor stability, and is unsafe. [0007] Also do not have the transmission that is suitable for the automobile of electric drive, locomotive at present. Traditional transmissions are not suitable for electric vehicles and locomotives and have been canceled. According to authoritative sources, it is not that the automobiles and locomotives suitable for electric propulsion do not need transmissions but do not have ...
