Problems solved by technology
[0006] The technical problem to be solved by the present invention is that the design function of the existing caliper parking brake is not comprehensive enough, that is, when the battery, motor or electronic control system fails, the parking brake force cannot be released, and the vehicle cannot move, resulting in traffic jams. There may be safety technical issues such as major traffic accidents on the highway, so an electronic parking brake device with emergency release function is proposed

Embodiment Construction
[0034] The following is attached figure 1 -5 The technical solution of the present invention is described in detail.
[0035] figure 1 As shown, the present invention provides an electronic parking brake device with an emergency release function, including a drive mechanism provided with a drive motor 3, a planetary gear reduction mechanism, a lead screw nut transmission mechanism and an actuator for releasing the parking brake. Mechanism; wherein: the motor 3 connects the motor shaft and the sun gear 15 of the planetary gear reduction mechanism through gears or belts, and the planetary gears are installed in the planetary ring gear 2 and closed with the planetary gear reducer housing 11.
[0036] The planetary gear reduction mechanism drives the screw nut transmission mechanism to rotate, and the screw nut transmission mechanism moves the nut 6 axially through the rotation of the screw 5 to push the brake piston 7, and the brake piston 7 presses the friction plate to brake t...

The invention relates to an electronic parking braking device with an emergency release function. The electronic parking braking device comprises a driving mechanism, a planetary gear reducing mechanism, a screw rod screw nut transmission mechanism (4) and a parking braking release executing mechanism, wherein the driving mechanism is provided with a driving motor (3). The electronic parking braking device is characterized in that the motor (3) is used for connecting a motor shaft with a sun wheel (15) of the planetary gear reducing mechanism through a gear or a belt, and a planetary gear is arranged in a planetary gear ring (2), is sealed by a planetary gear reducing mechanism casing (11) and is engaged with the planetary gear reducing mechanism casing (11). An inhaul cable mechanism is of a pure mechanical structure, compared with an electronic control system, the electronic parking braking device has the advantages that higher reliability and safety are realized, the operation of the mechanism is simple and convenient, and the braking can be easily relieved in emergency; the emergency braking release function is added, the problem of vehicle moving incapability caused by electronic braking system faults is avoided, and the occurrence of traffic accidents is avoided.
Description
technical field [0001] The invention is applied to a vehicle chassis system, and belongs to the technical field of manufacturing and safety of electronic brake systems for vehicles. Specifically, it relates to an integrated caliper type electronic parking brake device with an emergency release function. Background technique [0002] With the continuous advancement of automobile technology, more and more automobile systems have gradually changed from traditional mechanical control to electronic control. The electronic parking brake system uses electric energy to realize the functions of the traditional parking brake system. [0003] At present, in the technical field of electronic parking brake systems for motor vehicles, most of them use rear caliper integrated electronic parking brakes. The rear caliper integrated electronic parking brake system has comprehensive functions, convenient installation, and compact structure. The development trend of braking system. The power o...
