In this disc brake, a pair of brake pads has recesses in the outer peripheral surfaces thereof. A pad spring has a first pressing section extending axially and provided to a base, the first pressing section pressing, toward the trailing side, a first section to be pressed which is provided on the trailing-side side surface of side surfaces which form the recess of a brake padand which are raised outward in the radial direction of a rotor. Also, the pad spring has a second pressing section extending axially and provided to the base, the second pressing sectionpressing radially inward on the bottom surface of the recess of each of the pair of brake pads, the bottom surface being a second section to be pressed which is provided on an outer peripheral section.

Land vehicles and methods of operating land vehicles are disclosed. A land vehicle includes a frame structure, a plurality of wheels, and a brake system. The frame structure includes a front cage that at least partially defines an operator cabin and a rear compartment positioned rearward of the front cage in a longitudinal direction. The plurality of wheels are supported by the frame structure. Each of plurality of wheels is sized to permit direct integration of an electric motor therein.

A floating disc brake assembly having a disc brake rotor secured to a mounting assembly, such as a hat or a hat with a retention ring structured and arranged to fit within retention ring flanges of a plurality of rotor mounting tabs uniformly distributed about the mounting assembly. A method of uniformly transferring braking forces from a rotor of a brake assembly about a wheel hat component of the brake assembly and a kit of parts are also provided.

An elliptically interfacing gear assisted braking system may include an input shaft with a coupled input gear, a wobble plate, a rotor with a reaction gear, and an actuated brake mechanism, or brake. The input shaft may define an axis of rotation and the wobble plate may have a wobble axis disposed at a non-zero angle relative to the rotation axis. A set of face teeth disposed on one surface of the wobble plate may partially mesh with the input gear, and a set of wobble teeth on an opposite surface of the wobble plate may partially mesh with the reaction gear. Rotation of the input shaft may thereby cause rotation of the wobble plate and rotor. The brake may mate with the rotor and when actuated, slow the rotor with respect to the input shaft. Rolling contact forces between the surfaces of the wobble teeth and reaction teeth may then induce nutation in the wobble plate, thereby dissipating rotational energy.

A linkage structure of a reluctance unit and a brake unit and an exercise machine having the linkage structure are provided. The exercise machine includes a main body, having a resistance wheel and a control unit; a linkage member, connected with the control unit; a reluctance unit, corresponding to the resistance wheel and connected with the linkage member; and a brake unit, corresponding to the resistance wheel and connected with the linkage member. The control unit controls the motion of the linkage member so that the linkage member drives the reluctance unit to move between a reluctance position and a release position, and the linkage member drives the brake unit to move between a brake release position and a brake position.

An electric brake (1) with an electric motor. An electromechanical actuating unit is provided which has a planetary rolling contact gear unit (6) by means of which a rotating movement of the electric motor is translated into an axial movement of an actuating element (7). A brake shoe (8) is coupled as a brake element to the actuating element (7).

A bell for brake disc with integrated drum-in-hat auxiliary brake. The bell (2) includes an annular flange (5) configured to be coupled to a braking band (4) of a brake disc (1), and a drum (6) coupled coaxially to the annular flange (5), wherein the drum (6) accommodates or is configured to accommodate an auxiliary brake (7). The annular flange (5) and the drum (6) are separate elements joined together. The annular flange (6) has at least one recess (13). The drum (6) comprises a cylindrical body (14) and an auxiliary annular flange (15) positioned on a peripheral edge of the cylindrical body (14). The recess (13) has an annular shape coaxial with a common symmetry axis (X-X) and houses the auxiliary annular flange (15).
