Device for fixing a ventilated brake disk axially on the hub of a motor vehicle wheel

An axial fixing device for axially fixing an annular brake disk on a wheel hub of a motor vehicle, the annular brake disk having the same axis of rotation as the hub and including radial ventilation ducts regularly distributed about its periphery. According to the invention, the hub has axial guide pieces in relief, or "lugs", for co-operating with fluting in an inner peripheral edge of the disk to center the disk, to lock it angularly, and to guide it axially relative to the hub, each lug of the hub having a radial through channel for co-operating with a corresponding ventilation duct of the disk, and the disk is held axially in the hub with play by axial holding means disposed between the disk and the hub.

Lightweight reinforced brake drum and method for making same

The invention provides a lightweight brake drum (10) comprising a lightweight, tubular inner member (14) having a reinforcement wrapping retention pattern (e.g., groove) cast in the exterior surface thereof, a length of reinforcement material (e.g., wrapped wire, cable, mesh, fibers, etc.) (16) in communication with a reinforcement retention pattern (e.g., a groove around the inner member) (14), the drum including an outer shell (18). The inner member (14) and the outer shell (18) are made of lightweight materials. Single, or multiple layers of reinforcement material (e.g. wrapping) are applied (e.g., wrapped) around the inner member (14) to support and inhibit expansion of the inner member (14). Because the reinforcement material (16) provides support against expansion, the inner member (14) and the outer shell (18) can be made of lightweight materials. In preferred embodiments, a bonding layer (66) is applied to the exterior surface of the inner member prior to application of the reinforcement material thereon. In preferred embodiments the reinforcement material comprises a low-impedance material such as copper along with another material that has good tensile strength characteristics (e.g., steel, composite fibers, Basalt-fibers, etc.). Preferably, the inner member comprises at least one material selected from the group consisting of a aluminum-based metal matrix composite (MMC) with a particulate reinforcement, ceramic matrix composite (CMC), and carbon graphite foam.

Rotor and exciter ring

A rotor assembly with a cylindrical body having a radial disc that is perpendicularly aligned with a hub of a vehicle and an exciter ring through which a sensor detects rotation of the radial disc. The exciter ring is concentrically installed within the cylindrical body to define a gap between a flange thereon and the radial disc. Reluctance sections on the flange are axially aligned with the sensor to generate a signal indicative of rotation. Friction members engage the radial disc and generate thermal energy that is conducted a mounting flange. Thermal energy level may cause the rotor assembly to expand and change the alignment of the radial disc from perpendicular and non-perpendicular with respect to the hub. The gap allows the radial disc and exciter ring to independently move such that the reluctance sections remain axially aligned with the sensor and sensed information is an accurate indication of rotation.

Brake caliper including heat pipes

A brake caliper including a caliper body and heat pipes at least partially embedded within the caliper body. The caliper body includes spaced inboard and outboard portions. In addition, at least one of the portions includes piston bores. The caliper body further includes a connector between the inboard and outboard portions whose spacing permits brake pads and a periphery of a brake rotor to be received between the inboard and outboard portions. Also, the brake caliper includes pistons disposed in the piston bores to press the brake pads against the periphery of the brake rotor when brake fluid moves the pistons and the brake pads toward the brake rotor. As the brake pads heat the brake caliper, the heat pipes transfer heat away from the piston bores thereby cooling the brake caliper and brake fluid in, around, or near the piston bores.

Circuit for supplying ear-microphone bias power for ear/microphone in mobile terminal

Disclosed is a circuit for supplying ear-microphone bias power in a mobile terminal that reduces power consumption due to unnecessary ear-microphone bias when the terminal is in a sleep mode with an ear / microphone being connected to the terminal through an ear-microphone line. The ear / microphone has a call switch connected to the ear-microphone line. The circuit receives first and second powers through first and second power input terminals, respectively. The first power is supplied when the terminal is not in the sleep mode, whereas the second power having a voltage lower than that of the first power is supplied also in the sleep mode. The circuit supplies ear-microphone bias power, based on the first power, to the ear-microphone line when not in the sleep mode, and supplies power for detecting a switching operation of the call switch, based on the second power, to the ear-microphone line in the sleep mode.

Manufacturing method of high-strength light bi-metal brake drum and high-strength light bi-metal brake drum thereof

A manufacturing method of a high-strength light bi-metal brake drum includes the following steps: (a) blanking steel plates; (b) punching; (c) spinning, spinning an external edge of a semi-finished product obtained from the former step to be a cylindrical outer ring having a plurality of convex rings; (d) roll spinning, forming uniformly distributed inwards concave parts on an inner wall of the convex ring of the semi-finished product through roll spinning; (e) casting, casting a iron casting lining in the semi-finished product by a centrifugal casting method; (f) heat treatment, eliminating inner stress and enabling the iron casting lining to achieve a rigidity demanded by the brake drum; (g) processes of finish machining and the like. The bi-metal brake drum manufactured by the method can directly transmit a brake moment between the iron casting lining and a steel housing, fixing pieces, such as a bolt or a rivet and the like, are unnecessary for assembling the outer ring and the lining of the brake drum, and service life of the brake drum is prolonged; simultaneously, an originally designed structure combination of a drum disc, the lining and a thin wall of the outer ring is not changed, so that phenomena of crack caused by too thick drum wall and too much temperature difference are reduced, and braking conditions are improved.

A brake drum has its strength elevated in its disk portion. The brake drum is formed from a composition having ceramics dispersed in a matrix. The disk portion has a high ceramic content and thereby a high strength. The brake drum has a disk portion and a cylindrical portion. The disk portion has a first ceramic content by volume and the cylindrical portion has a second ceramic content by volume that is less than the first ceramic content by volume as a result of the application of a higher compression ratio to the disk portion.

Vehicle wheel structure

A drum brake for braking a wheel disposed on the inside in the radial direction of an electric motor. The drum of the drum brake and an electric motor are disposed separate from each other, and thus wear powders of a brake shoe do not adhere to a permanent magnet of the electric motor. As a result, the wear powders do not adversely influence the performance of the electric motor, and the performance of the electric motor is maintained. The electric motor and the drum brake are disposed concentrically, so that the width of the wheel is reduced. Thus, a small and compact wheel is realized.
