Abstract: An actuator unit for a hydraulic brake mechanism on two-wheelers, comprising a housing fastened to the handlebar, a brake cylinder being arranged substantially perpendicular to the handlebar in the housing, a piston movable in it and a brake lever acting on the piston at an intermediate portion remote from either end of the lever, the lever being mounted at one end thereof to rotate relative to the housing, wherein the brake lever is mounted adjustably movable with respect to an axis substantially at an end of the lever, the axis being unchangeable in position but rotatably mounted to the housing, the adjustment option being provided for by the adjustment mechanism, wherein the lever, the adjustment mechanism and the axis rotate together relatively to the housing upon operation.

Abstract: A brake pedal crash safety device for a vehicle in which a brake pedal arm is rotatably mounted to a first vehicle body component and has a first locking element, shaped as a circle-sector and having its geometrical center at a center of movement of the brake pedal arm. A second locking element is mounted to a second vehicle body component. The second locking element is mounted a predetermined distance from the first locking element. The predetermined distance is constant and has a predetermined amount of allowable movement therebetween for a brake pedal arm position. A crash force applied to a front of the vehicle displaces the first vehicle body component toward the second vehicle body component and the predetermined amount of allowable movement between the first and second locking elements will be closed, irrespective of a current pedal position, thereby preventing further rotation of the brake pedal arm through interlocking first and second locking elements.

A shifter piston is disposed within the interior of the shifter housing and is movable in first and second directions. The shifter piston defines first and second chambers within the interior of the shifter housing. The fluid port communicates with the first chamber, and the opening communicates with the second chamber. The shifter piston includes a passageway that provides communication between the first and second chamber defined within the interior of the shifter housing. A shift actuator is supported on the shifter piston for movement therewith and extends through the opening provided in the shifter housing.

Abstract: A bicycle brake operating device is provided with a handlebar bracket, a brake lever, an operation unit and a detection device. Rotation of the operation unit is detected by the detection device. The operation unit is arranged so that it does not readily hinder a braking operation. The operation unit also arranged so that it us not readily damaged when the bicycle falls over.

Abstract: The actuator has a gear unit with a gear housing and a motor unit with a motor housing and an internally located rotor with a drive shaft, and a cylindrical bearing housing on the drive side. The bearing housing protrudes, along with a bearing and the drive shaft ducted therein, into an opening in the gear housing. The motor housing is flange-mounted, along with a drive shaft mounted therein, to the gear housing. The outside of the bearing housing and the inside of the opening in the gear housing have been geometrically mutually harmonized such that clamping points and tension-free places will form between them when the actuator has been assembled. The pretensioning force resulting therefrom produces a permanent frictional engagement between the outer circumference of the bearing and the bearing support or the bearing shell located opposite it. The operating life of an actuator of such type is increased.

Abstract: A spring damper for absorbing vibration of a double coil spring is made of elastic material and composed of a cylindrical body, outer-wall convex portions, and inner-wall convex portions. The spring damper is arranged in an annular space formed between an outer coil spring and an inner coil spring of the double coil spring, so that the outer-wall convex portions push the outer coil spring in a radial outward direction and the inner-wall convex portions push the inner coil spring in a radial inward direction. Longitudinal ends of the cylindrical body are prevented from being hooked by spring wires of the outer or inner coil spring, when the double coil spring is expanded and compressed.

Abstract: A reduction in the size of a housing for containing a magnetic sensor is provided for a throttle device for a vehicle in which the turning amount of a throttle grip is detected by use of the magnetic sensor. An extension part of the throttle grip is provided at its outer periphery with an enlarged diameter part for holding magnets of the magnetic sensor. A right switch box is provided with Hall sensors of the magnetic sensor, and the enlarged diameter part and each of the Hall sensors are opposed to each other in the axial direction of a right handle bar. The throttle grip is urged toward the throttle full-closing position by a grip urging mechanism. The throttle full-closing position is maintained by only an urging force exerted from the grip urging mechanism.

Abstract: An electronically controlled floor mounted pedal assembly with a position sensor includes a base. A control arm is pivotally mounted to the base member at a control arm pivot axis, and a pedal arm is pivotally mounted to the base member at a pedal arm pivot axis. The control arm free end is positioned adjacent an inner surface of the pedal arm. A friction generating member mounted on the control arm free end contacts a pedal arm friction member positioned on the inner surface of the pedal arm to generate frictional hysteresis force. A spring positioned between the base member and the control arm free end initially biases the control arm against the pedal arm. A position sensor supported on the base member about the control arm pivot axis senses angular rotation of the control arm about the control arm pivot axis as the pedal arm rotates about the pedal arm pivot axis.

Abstract: A steering column assembly includes a first jacket defining a first bore and a second jacket defining a second bore aligned with the first bore prior to collapse of the first jacket and the second jacket. A jacket connector extends through the bores to interconnect the first jacket and the second jacket. The jacket connector includes a pre-determined shear resistance, above which the jacket connector is sheared to permit telescopic movement between the first jacket and the second jacket. Accordingly, in response to an axial load greater than the pre-determined shear resistance of the jacket connector being applied to one of the first jacket and the second jacket, the jacket connector shears, permitting the telescopic movement. The jacket connector includes a pin defining a pin bore. The pin bore defines a cross sectional area, with the pre-determined shear resistance depending upon the cross sectional area of the pin bore.

Abstract: A porous insert for a gearbox or transmission which retards fluid motion and flow within the device when it is subjected to rapid acceleration. The insert may be fabricated of any porous material such as open cell plastic foam, a porous ceramic or sintered metal and is shaped to conform to and is installed in a bottom rear region of the transmission housing. The insert retards motion of the fluid during rapid acceleration, preventing pump starvation and permitting a smaller charge of fluid to be placed in the gearbox or transmission.

Abstract: An eccentric bottom bracket for a bicycle. The eccentric bottom bracket includes opposing first and second members. The first member and the second member each include a body and a flange. Each body is sized and shaped to penetrate an opening of a bottom bracket shell of a bicycle. Each flange is sized and shaped to prevent complete admittance of the member into the bottom bracket shell. Each body also has a bearing guide with an axis that is parallel to but offset from a center axis of the bottom bracket shell when that body is fit into the bottom bracket shell. The eccentric bottom bracket also includes a tightening assembly for selectively applying a compressive force between the body of the first member and the body of the second member. The compressive force secures the first member and the second member to the bottom bracket shell.
