The pedal block is a rigid part of the body, with a pedal body (2) and with an actuating surface (3). The pedal body (2) has at least one inner metal core (8) and a plastic jacketing (9) surrounding the metal core (8).

Abstract: A propelling transmission control apparatus for a working vehicle having a hydrostatic stepless transmission comprises a variable displacement type hydraulic pump (35), a change speed control mechanism (80) for converting a displacement of a control device (55) to a control displacement for varying a swash plate angle of the hydraulic pump, a fixed displacement main hydraulic motor (36) and a variable displacement auxiliary hydraulic motor (37) connected in series to the hydraulic pump. A common output shaft receives rotational output from both motors. A control piston (35) varies the swash plate angle of the auxiliary hydraulic motor, is connected to a pressure oil supply line (39) for supplying both hydraulic motors with pressure oil, and is operable to vary the swash plate angle of the auxiliary hydraulic motor (37) such that the auxiliary hydraulic motor (37) has an increased volume with a pressure increase applied to the control piston (38).

Abstract: A pedal mechanism 20 requires a friction mechanism for producing the force hysteresis in the pedal to ensure the correct, desirable pedal ‘feel’. A pedal arm 18 is pivoted in a housing 24. Friction is produced with a piston 28,128 which is urged by resetting springs 30,32,130,132 into frictional contact with a friction pad 36,136 which is fixed in the housing. Relative angular movement between the pedal 18 and the pad 36,136 when the pedal is depressed causes the point of contact between the pad and the piston 28 to move relative to the housing 24. This movement is resisted by friction between the pad and the piston, and by the springs which have to be compressed to allow the movement to take place. The same springs provided a restoring force to return the pedal to its initial position when it is released.

Abstract: An assisting apparatus for using power from a rotating member to assist the operation of a bicycle transmission includes a mounting unit and an input transmission member coupled to the mounting unit, wherein the input transmission member moves to at least a first input position, a second input position and a third input position. An output transmission member is coupled to the mounting unit, wherein the output transmission member moves to at least a first output position, a second output position, and a third output position corresponding to the first input position, the second input position and the third input position of the input transmission member, respectively. A rotating member engaging member moves between a rotating member engaging position and a rotating member disengaging position, and a motion transmitting mechanism is provided for transmitting motion from the rotating member engaging member to the output transmission member.

Abstract: Automatic neutral finder apparatus for a motorcycle transmission, for automatically locating and positively engaging the transmission's neutral position. A preferred embodiment of the apparatus includes a shifter cam rotatable about an axis through predetermined rotational displacements for effecting gear shifts and having a neutral position; a stop indexed to the neutral position of the cam; a plunger actuable for engaging the stop to stop rotation of the cam when the cam is at its neutral position; and a circuit associated with the plunger and including a switch operable by the motorcycle operator for actuating the plunger to engage the stop. The plunger is further actuable for disengaging the stop, and the switch is preferably operable by the motorcycle operator for actuating the plunger to disengage the stop.

Abstract: Some automobiles have mechanisms for adjusting the height of accelerator and brake pedals, and any clutch pedal, so that drivers large and small can adjust the pedals to the best height. All pedals are adjusted by a single reversible electric motor having a shaft connected directly or by a flexible shaft to the adjusting mechanisms. If any fault develops in any mechanism, the pedals may not be adjusted to the same height, which is hazardous to the driver. A safety switching system detects any serious misalignment of the pedals and de-energizes the motor. The system comprises separate switches which are operable by adjustment of the pedals, and are electrically connected in series with the power supply circuit for the motor. When the pedals are aligned, the bridging contactors of the switches are aligned and are effective to maintain the electrical continuity of the motor circuit. Each contactor has three contact sliders which successively engage staggered tabs on contact strips for the respective pedals.

Abstract: A motorcycle shifting arrangement is connected to the transmission of the motorcycle for shifting the transmission between a higher gear and a lower gear. The motorcycle includes an original shifting structure having an original shift pedal pivotally mounted on an original pivot shaft coupled to the transmission at a location adjacent a foot rest attached to a bottom portion of the motorcycle. A supplementary shifting structure is constructed and arranged to permit alternative shifting of the motorcycle while the motorcycle operator has his or her legs in a raised, extended position resting upon a highway peg attached to a supporting structure at a forward location of the motorcycle.

Abstract: A shift control system includes a shift pedal (13), a first linkage mechanism (16, 18, 19, 20) for transmitting a downward displacement of the shift pedal to the stepless transmission to change a shift position of the stepless transmission, a retaining mechanism (30, 40, 41, 42) for producing a retaining position corresponding to the shift position to retain the shift position of the stepless transmission, and a shift lever (26) for setting the retaining position retained by the retaining mechanism. A second linkage mechanism (34, 35, 36) is provided for transmitting of an operating displacement of the shift lever to the shift pedal to displace the shift pedal to a depressed position corresponding to the retaining position set by the shift lever and retained by the retaining mechanism. The shift lever, retaining mechanism and second linkage mechanism are attachable and detachable independently of the first linkage mechanism.

Abstract: A motorcycle transmission shifter assembly including a cam drum having at least two pins extending therefrom, and a shift mechanism engageable with the pins. The shift mechanism includes a tooth that is operable to engage a first one of the pins to rotate the drum in a first direction and a stop that is operable to engage a second one of the pins to prevent over-rotation of the drum in the first direction. Preferably, the shift mechanism includes a shift pawl and a shift lever and the stop is mounted on either the shift pawl or the shift lever. Additionally, the shift mechanism can include a second stop mounted on the other of the shift pawl or the shift lever, the second stop being operable to engage a third one of the pins to prevent over-rotation of the drum in a second direction.
