Embodiment Construction

[0009] Pre-calculate the rotational speed of the motor main body (2), design Motor reducer (3) reduction ratio, the output shaft is connected to the drive wheel (4), when Motor Body(2) In the case of power supply, the normal output is driven by large torque power Drive Wheels (4) walk, Motor Body(2) At the same time of power failure, motor The electromagnetic power-off brake (1) is activated to achieve wheel braking, and the vehicle will not slide downhill due to gravity on the slope. The overall application of the power-off braking deceleration motor to the drive saves a lot of complicated procedures, which is beneficial to reduce the weight of the vehicle and the complicated design.

Abstract

The invention relates to a method for driving an electric mountain-climbing track car, wherein a power-off braking speed-down motor is used as a driver, so that complex variable speed and speed-down structure problems in other driving ways are solved, and simultaneously, greater climbing toque can be provided, and when driving loses electric power, instant braking can be realized, and therefore, accidents of cars gliding down naturally on a gradient track due to the loss of power are prevented.

Description

technical field [0001] The invention relates to a driving method of an electric mountain-climbing rail vehicle, which belongs to the technical field of transportation tools. Background technique [0002] Existing electric railcars mainly run on flat rails, and the requirements for torque are not very high, and there are not too high requirements for safety when the drive loses power. When the power is lost, the vehicle will slide down due to gravity and slope. This structure is not suitable for climbing on a track with a slope. When running on a track with a slope, it is easy to cause the vehicle to be out of control due to accidental power loss, which will lead to an out-of-control accident on the slope. Contents of the invention [0003] In order to solve the need for large torque drive and safety control in the case of power failure when climbing mountains and slopes, the present invention provides a new method, using a power-off braking deceleration motor as the drive ...
