Problems solved by technology

[0003] However, at present, most electric vehicles are driven by the front wheels, and the hand brakes all brake the rear wheels. The braking force is relatively small, and the wheels cannot be completely locked.
When an electric vehicle is parked on a slope, use the handbrake, and the vehicle is likely to slide because it is not completely locked; when an electric vehicle starts on a slope, the vehicle has no power at first, and the vehicle may reverse It is very detrimental to driving safety

Abstract

The invention discloses a gear P executing mechanism for a speed reducer of a Plug-in electric automobile. The gear P executing mechanism comprises a gear P motor, a transmission assembly, a pallet, a ratchet wheel and a second elastic component, wherein the transmission assembly comprises a gear shaft, a gear matched on the gear shaft, a driving shaft, a conical driving sleeve and a first elastic component arranged on the driving shaft, a rack connected with one end of the driving shaft, and a supporting seat arranged below the driving shaft, the conical driving sleeve, the first elastic component and the rack; the gear shaft is connected with an output shaft of the gear P motor; one end of the pallet is provided with a ratchet; and the ratchet is meshed with a tooth socket on the ratchet wheel. The gear P executing mechanism has a simple and reliable structure, is convenient to use, has a very good braking effect on the electric automobile, and can be used for greatly enhancing the parking reliability of an electric vehicle.

Description

technical field [0001] The invention relates to a P-gear actuator for a plug-in (external charging type) reducer for an electric vehicle. Background technique [0002] Electric vehicles have great market potential because of their advantages of energy saving, environmental protection and low fuel consumption. More and more people choose to buy electric vehicles. [0003] But most electric vehicles are front-wheel drive mode at present, and its hand brake all is to brake the rear wheel, and the braking force is relatively small, and the wheel cannot be locked completely. When an electric vehicle is parked on a slope, use the handbrake, and the vehicle is likely to slide because it is not completely locked; when an electric vehicle starts on a slope, the vehicle has no power at first, and the vehicle may reverse It is very detrimental to driving safety. Contents of the invention [0004] The purpose of the present invention is to provide a P gear actuator for a plug-in ele...
