Description

Multi type electric parking caliper {Multi type electric parking caliper}

The technical field of the present invention relates to a multi-type electronic parking caliper, and more particularly, to a multi-type electronic parking caliper implemented to correspond to all vehicle types.

The brake of the vehicle is a device that regulates the speed of the vehicle in motion and controls the movement of the vehicle body, and generates 'braking force' by converting the 'kinetic energy' of the vehicle into 'heat energy'. The parking brake has a large caliper parking brake and a drum parking brake, and the caliper parking brake has a hand parking brake, a foot parking brake and an electric parking brake (EPB). The drum parking brakes also have hand parking brakes, foot parking brakes and electronic parking brakes. Among these, attention is focused on the electronic parking brake that can be operated by an electrical signal, and the direction of the future technology has been developed and reviewed accordingly.

In the case of the EPB, when the switch is operated, the brake operation signal is transmitted to the actuator from the EPB electronic control unit (ECU) to which the signals of the brake and the speed sensor are input, and the actuator activates or releases the parking brake. In the case of the rear side EPB of the drum in hat (DIH), these actuators are used to operate the parking brake with an electric signal, which is operated separately from the service brake using the caliper and shares the hydraulic line. As a result, the brake pedal is not affected by the parking operation.

In addition to the EPB of DIH, the EPB can be realized directly in the caliper, and if the EPB is realized directly inside the caliper, the number of parts can be reduced compared to the existing EPB, which is advantageous in terms of cost and weight. It is advantageous that the package construction can be facilitated. However, when the EPB is realized in the caliper, the service brake and the hydraulic line are shared, which directly affects the brake pedal. In other words, when the parking brake is operated, the brake pedal is pushed forward slightly by operating the piston through the electric motor, so that more brake fluid must be supplied into the cylinder, and when the parking release is released, the brake pedal is pushed backward. It gives an unpleasant feeling and anxiety, and the merchandise is greatly reduced.

Korean Laid-Open Patent Publication No. 10-2009-0062629 (published on June 17, 2009) discloses a caliper type electronic parking brake device that realizes an electronic parking brake inside a caliper. According to the disclosed technology, a cylinder is hydraulically filled; In constructing an electronic parking brake on a caliper having a first piston for activating the parking brake and the service brake while moving left and right by hydraulic pressure filled in the cylinder, a second piston is provided opposite the first piston of the cylinder, An electric motor is connected to the second piston, and an EPB control signal for the electric motor is sent to the ESC hydraulic control unit (HCU) to control the brake valve. By eliminating the kick back, it is possible to greatly improve the commerciality of the electronic parking brake, and it can be easily configured with fewer parts, which can greatly contribute to cost reduction.

Korean Patent Laid-Open Publication No. 10-2017-0092198 (published on Aug. 11, 2017) discloses an electronic disc brake, which includes a disk rotating with a wheel, a caliper housing for operating pad plates provided on both sides of the disk, and a caliper. A piston provided in the housing to press the pad plate against the disc, a spindle rotatably installed in the caliper housing to advance and retract the piston, an electric motor for rotating the spindle, and a reduction gear for transmitting the rotational force of the electric motor to the spindle. And an actuator having a device, wherein the reduction device includes a power connection unit directly connected to the electric motor, a first reduction gear unit and a second reduction gear unit for sequentially connecting the power connection unit and the spindle, The reduction gear unit is characterized by consisting of a worm gear. According to the disclosed technology, by using the helical gear as the power connecting unit of the reduction gear and the worm gear as the reduction gear unit, compact size and low noise can be realized, and the first reduction gear unit uses a worm gear with a large reduction ratio. It is possible to prevent the reversal of the actuator spindle when the electric motor is turned off, and the worm wheel of the worm gear and the second reduction gear unit can be provided at the same height to realize a compact size, and also the worm shaft of the first reduction gear unit. By preloading with a seamount that is opened in different directions, it is possible to prevent the shaft out of the engaged gear and worm shaft that may occur during power transmission.

In the conventional technology as described above, in the case of a vehicle using a rear electronic parking (EPB) type brake, when the high-performance brake for tuning is mounted, the parking brake, auto hold and smart cruise functions cannot be used. . In the conventional technology as described above, since the shape, position, and structure of the vehicle link of the electronic parking motor are different for each vehicle type, various motors can be used, and the resistance values of the motor terminals for each vehicle model and manufacturer are different. Therefore, each electronic parking caliper must be implemented for each motor, that is, the electronic parking caliper that can be installed at an angle corresponding to the motor has to be implemented.
