Problems solved by technology

[0003] Mechanical braking is to block the motor shaft through mechanical devices to slow it down, such as electromagnetic brakes, electromagnetic clutches and other electromagnetic brakes. After long-term use of electromagnetic brakes, the braking system will fail unexpectedly during driving, and the driver cannot Safe and effective braking of the vehicle, the vehicle will automatically slide due to inertia, which may easily lead to accidents
[0004] Therefore, it is necessary to design a method that can effectively brake the vehicle, decelerate the vehicle, A motor brake deceleration device for new energy vehicles that can effectively brake the vehicle to avoid accidents

Abstract

The invention relates to the field of new energy vehicles, in particular to a motor brake deceleration device for new energy vehicles, including a lower installation box, an upper installation box, a drive assembly and a primary deceleration assembly, etc.; the top of the lower installation box is connected by fasteners The upper installation box is connected in the way, the lower installation box and the upper installation box are jointly provided with a drive assembly, and the lower installation box and the upper installation box are connected with a primary deceleration assembly in a common rotation type. During short braking, the position of the eight-sided mating shaft and the splined sliding sleeve can be switched, thereby changing the direction of power transmission. If the number of teeth is known, the rotation speed of the spline bevel gear shaft will slow down, so as to achieve the purpose of decelerating the car.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a motor braking deceleration device for new energy vehicles. Background technique [0002] As global environmental and energy issues become increasingly prominent, in order to implement the concept of energy saving and environmental protection, more and more users choose electric vehicles for travel. Electric vehicles, as the name implies, are vehicles that are mainly driven by electricity. The braking methods mainly include mechanical braking and electrical braking. [0003] Mechanical braking is to block the motor shaft through mechanical devices to slow it down, such as electromagnetic brakes, electromagnetic clutches and other electromagnetic brakes. After long-term use of electromagnetic brakes, the braking system will fail unexpectedly during driving, and the driver cannot Safe and effective braking of the vehicle, the vehicle will slide automatically due to inertia, whi...
