To reduce, if not entirely eliminate brake drum howling and squealing when the brakes are applied, a plurality of stabilizing sections are cast on the radially outer surface of the flange. The stabilizing sections are arranged in equally circumferentially spaced apart relation. Each stabilizing section is slotted or notched to form a plurality of circumferentially spaced serrations to increase flexibility.

Abstract: A parking brake for the automatic transmission mechanism of a vehicle so constructed as to affect no adverse influence on the operation of the automatic transmission mechanism even though a change lever is positioned in a parking range while the vehicle is running. The parking brake includes a first roller fixedly disposed to cooperatively rotate with an output shaft; a second roller coaxially movable with the first roller but disposed not to rotate; a restricting unit disposed at a facing surface between the first roller and the second roller to restrict the rotation of the first roller when the first and second rollers are in close adherence; and a driving unit for slidingly moving the second roller according to the selection or non-selection of the change lever to the parking position to couple and detach the first and second rollers.

Abstract: When it has been determined that a termination condition of brake TRC control has been fulfilled, SM valves 50FL and 50FR and a motor 80 are continuously placed in an ON state, and along with this, SR valves 70FL and 70FR are switched off, and furthermore holding valves 46FL and 46FR and pressure-reducing valves 48FL and 48FR of driving wheels are changed from an on-off switching state to an ON state, and termination control is initiated. Because of this, high-pressure brake fluid on the wheel-cylinder 2FL and 2FR side is expelled via the pressure-reducing valves 48FL and 48FR by drive of the motor 80. Consequently, high-pressure brake fluid can rapidly be expelled immediately after brake TRC control, and along with this, oil-shock noise can be alleviated.

Abstract: An ABS sensor bracket made up of two mounting wing plates engaged to a sensor receiver. The sensor receiver is generally cylindrical and is mounted between the wing plates such that the sensor receiver is asymmetric axially relative to the caliper anchor plate. When viewed from the side, there is a shorter end of the sensor receiver jutting out a shorter distance from the wing plates than an opposite longer end of the sensor receiver. In one embodiment, a first end of the sensor receiver has an outer diameter circumference greater than that of the opposite second end. The caliper anchor plate has an outer edge slot for mounting of the ABS sensor brackets. The outer edge slots are generally ‘U’ or ‘V’ shaped. There are mounting holes in the outer radial areas bordering the outer edge slots.

Abstract: A contactless eddy current brake for cars is disclosed. In the brake, two cores are arranged around the edge of a brake disc while being spaced apart from each other at an angle of 90°. Each of the cores is wound with a coil, thus forming an electric magnet. A speed sensor is positioned around the axle, thus sensing revolutions of the wheel. A control unit calculates a DC or AC control current in response to a speed signal output from the sensor, thus outputting an appropriate control current value to the coils. A current amplifier supplies the control current value from the control unit or a current value from a brake pedal to the coils of the cores. The control unit allows a DC current to be supplied to the coils when the car runs at a high speed or allows an AC current with different phases to be supplied to the coils when the car runs at a low speed or is stopped on a slope.

Abstract: A vibration damper for a seat suspension system is disclosed with a shock absorber which dampens seat vibrations when the shock absorber is coupled to the seat suspension system. The shock absorber includes a dampening cylinder housing with a dampening piston slidable therein. The dampening cylinder housing is coupled to one of the vehicle and seat, such as to the floor of the vehicle. An elongated latch engaging member, which may be in the form of a dampening piston rod is coupled to the dampening piston. A latch is shiftable between first and second positions. When in the first position the latch engages the dampening rod, and when in the second position the latch disengages the dampening rod. When engaged to the dampening rod, the latch couples the dampening rod to the other of the vehicle and seat so that the shock absorber applies a dampening force to the seat. Conversely, when the latch disengages the dampening rod, the shock absorber is relieved from applying a dampening force to the seat.

Abstract: A hydraulic shock absorber includes an inner cylinder filled with a working oil, an outer cylinder, and a reservoir defined between the inner and outer cylinders. A piston is slidably disposed within the inner cylinder so as to divide the interior of the inner cylinder into an upper cylinder chamber and a lower cylinder chamber. A piston rod is connected to the piston. A tubular member is disposed between the inner and outer cylinders and has a radial port. A damper mechanism is attached to the outer cylinder so as to control the flow of the working oil to produce a damping resistance. The outer cylinder includes a mounting projection with a substantially flat top surface on which the damper mechanism is secured. A sleeve has one end inserted into the port of the tubular member and the other, flanged end terminating at the top surface of the mounting projection. A first sealing element is secured between the sleeve and the port to provide a seal between the sleeve and the tubular member.

A telescopically adjustable brake rod is disposed within the frame tubes, between the brake lever and the brake device, and includes two parallel rods of which one is interconnected with the brake lever and the other is interconnected with the brake device. An axial longitudinal adjustment of the frame tubes to the desired vertical position synchronously causes a corresponding alteration of the length of the brake rod. At least one device is provided for locking the frame tubes and the parallel rods.

Abstract: An improved magnetorheological fluid damper is provided which closely approximates ideal performance requirements by providing an increased turn-up ratio and improving the linearity of damping force response. The MR damper includes a plurality of concentric annular flow gaps formed between concentrically mounted flux rings positioned on a piston core. By utilizing multiple flow gaps, the present damper increases the overall magnetorheological damping affect thereby creating a higher damping force and an increased tun-up ratio for a given piston size. Alternatively, the present multiple flow gap design permits a given damping force requirement to be achieved with a piston having a significantly reduced length thereby permitting a longer piston stroke. Also, multiple flow gaps permit greater design optimization for controlling damping force linearity.
