Embodiment Construction

[0040] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0041] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0042] This embodiment relates to a differential limited-slip locking mechanism based on electronic parking. This mechanism is generally used to realize the escape of the vehicle when one or some wheels of the vehicle slip and the vehicle falls into a slipping predicament. The differential limited-slip locking mechanism as a whole includes a brake caliper arranged at the driving wheel of the vehicle (that is, the wheel that is driven to rotate by the output power of the engine, thereby realizing the vehicle's travel), and a power wheel arranged at the brake caliper. The unit and the execution unit that transmits the power of the power unit to realize the locking of the brake caliper on t...

Abstract

The invention provides a differential slip limiting locking mechanism based on electronic parking and a vehicle slip escape method. The differential slip limiting locking mechanism based electronic parking comprises brake calipers arranged on two driving wheels in at least one pair of driving wheels on a vehicle and a differential mechanism connected in series between the two driving wheels; and the differential slip limiting locking mechanism also comprises a signal acquisition unit located on the vehicle and used for collecting vehicle operating condition signals, a lock switch capable of sending out an on or off signal, power units arranged at the brake calipers, execution units receiving output power of the power units to drive the brake calipers to lock brake discs and a control unitconnected with the lock switch, the signal acquisition unit and the power units. The differential slip limiting locking mechanism based on electronic parking can be combined with an electronic parkingtechnology, provides a differential slip limiting locking structure which is low in cost and conducive to popularization, and has good practicability.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to an electronic parking-based differential limited-slip locking system. The invention also relates to a vehicle skidding and escape method based on the electronic parking differential speed limit slip locking mechanism. Background technique [0002] When the car is running on a curve, there will be a speed difference between the inner and outer wheels. At this time, a differential must be used to adjust, but the differential also has a big disadvantage, that is, when any of the driving wheels slips, The differential will continuously transmit power to the idling wheels without resistance, causing the wheels to be unable to get out of trouble. In order to prevent the weakness of the wheels from slipping and being unable to get out of trouble, the differential lock is applied, but the locking and disengagement of the differential lock will affect the stability of the vehicle. For ...
