The hydraulic transaxle further includes an oil-supply mechanism capable of displacing the locking member to the second position.

A rotation locking device includes a locking module and at least one engaging member. The at least one engaging member is rotatably coupled to the locking module. The locking module is configured to engaging and disengage the at least one engaging member, thereby refraining the at least one engaging member from rotating relative to the locking module.

A brake plate of a fall arrest system is provided for protecting users during a fall. The brake plate comprises a body having a central opening. The central opening defines an inner circumference of the body. The brake plate comprises a plurality of ratchet gear teeth disposed along the inner circumference of the body. Further, the brake plate comprises at least two slots on the body, wherein the at least two slots are disposed diametrically opposite to each other. Each of the at least two slots is curved and extends along a portion of an outer circumference of the body.

Disclosed is an actuator for a parking brake. In accordance with an aspect of the disclosure an actuator for a parking brake includes a motor generating power; a reduction gear portion configured to transmit the power of the motor to a parking portion implementing the parking braking of a vehicle; a locking portion configured to limit rotation of the reduction gear portion; and a housing in which the motor, the reduction gear portion, and the locking portion are accommodated; wherein the locking portion is configured to a lock gear coupled to the reduction gear portion to rotate together, a lever provided to be engaged with the lock gear through a hinge motion, an elastic member elastically supporting the lever toward the lock gear, and an electromagnet member that generates electromagnetic force when the power is applied to separate the lever from the lock gear.

Disclosed is an actuator for a parking brake. In accordance with an aspect of the disclosure an actuator for a parking brake includes a motor generating power; a reduction gear portion including a driving gear rotating in association with a drive shaft of the motor, and a sun gear coupled to the drive gear to rotate together; a housing in which the motor and the reduction gear portion are accommodated; and a locking portion configured to limit rotation of the reduction gear portion; wherein the locking portion is further configured to a pair of locking members configured to restrain and release at least a part of a rotation shaft of the sun gear, a plurality of elastic members supporting each of the locking members in a direction of the rotation shaft of the sun gear, an electromagnet member configured to separate the pair of locking members from the sun gear by generating an electromagnetic force when the power is applied.

A toothed safe braking apparatus for use in robotic joint, comprising an electromagnetic telescoping apparatus (6) and a friction engagement component (10). The friction engagement component (10) is mounted on a shaft (C) of the robotic joint and comprises a brake lock ring gear (1) provided with a first center fitting hole (12), the brake lock ring gear (1) being provided with teeth (11) arranged on the outer circumferential surface thereof, a pretension ring (2) provided with a second center fitting hole (13), and a brake hub (4) provided with a first end surface (14), a second end surface (15), and an outer circumferential surface (16). On a locked position, a working bit (17) of the electromagnetic telescoping appamtus (6) can be engaged with the teeth (11) on the brake lock ring gear (1) of the friction engagement component (10); and, on an unlocked position, the working bit (17) of the electromagnetic telescoping apparatus (6) can be disengaged from the teeth (11) on the brake lock ring gear (1) of the friction engagement component (10). The brake lock ring gear (1) and the pretension ring (2) are arranged in parallel via the first fitting hole (12) and the second fitting hole (13) to be friction engaged on the outer circumferential surface (16) of the brake hub (4).

Axial adjustment device (1), comprising a first disk (2) which is rotatable and axially displaceable both in a first circumferential direction (I) and in a second circumferential direction (II), namely a circumferential direction counter to the first circumferential direction (I), and a second disk (3) which is locked against rotation in the first circumferential direction (I) and is rotatable in the second circumferential direction, wherein the second disk (3) has an activating element (8) on its end side facing away from the first disk (2), and wherein the first disk (2) and the second disk (3) each have, on their mutually facing end surfaces, at least three identically formed depressions (4) which lie opposite one another in each case in pairs and thus form at least three pairs of depressions, wherein a rolling element (5) is arranged in each of the pairs of depressions, wherein the depressions (4) each have a slope in the first circumferential direction (I) from a lower dead centre (6) towards an upper dead centre (7), and an actuation arrangement, comprising such an axial adjustment device.

A swing type wheel locking device includes a wheel axle and a pivoting part. A wheel body has an outer wheel face and an axle hole fitted on the periphery of the wheel axle at a position close to the axle end part. A plurality of positioning concave parts are arrayed in a circle on the outer wheel surface. A swing type wheel locking component is pivoted on the wheel axle and has a pivoting end and a swing section. The pivoting end is pivoted on the pivoting part, so that the swing section can be forced to swing, and by choosing different swing angles, it can be shifted between a locked position and released position. When a clamping convex part of the swing section is at a locked position, it is locked right inside the corresponding positioning concave part. Thus, the wheel body is locked against rotation.
