Abstract: A brake pedal emulator extends and connects between a support structure and a brake pedal pivotally engaged to the support structure at an axis. The brake pedal emulator includes a rotational damping device operatively connected to the brake pedal for driven rotation as the brake pedal moves about the axis.

Abstract: An anticollision decelerating and emergency brake apparatus of automobile is disclosed. The objects of the invention is realized by the following: an anticollision decelerating and an emergency brake apparatus of automobile constituted by clutch (1), a energy-storage assembly (2), a brake force transmission assembly (3), a combined solenoid valve assembly (4), a housing (5), a variable diameter assembly (6), a reset mechanism (7), and so on. The apparatus of the invention will auto brake to effective prevent and avoid traffic accident, and the damage degree can be minimized.

Abstract: A gear mechanism for a brake system can be coupled on the inlet side to an actuating drive of the brake system via a drive shaft which can be driven rotationally by the actuating drive. The gear mechanism can be coupled on the output side to a brake unit of the brake system via an output shaft. The brake unit has at least one brake. The gear mechanism has a first and a second gear train having different transmission ratios. Furthermore, the gear mechanism is configured in such a way that, in order to apply the brake, only the first gear train and, in order to release the brake, only the second gear train of the gear mechanism transmits a drive torque of the actuating drive to the output shaft. The transmission ratio of the second gear train is greater than the transmission ratio of the first gear train.

Abstract: A motorcycle having a speed control rotary throttle grip and a pivoted brake lever both mounted on a steering handlebar, is provided with a split clamp ring surrounding the throttle grip and movable to releasably clamp the throttle grip against rotation from a preset position of cruising speed. A catch pin supported by one section of the split clamp ring is movable with the other section of the clamp ring to releasably secure the sections together. The catch pin is movable either manually by physical force or automatically by movement of the brake lever during braking of the motorcycle speed. Manual force may be applied to move a clamp lever, while automatic operation is achieved by movement of the brake lever into engagement with the clamp lever.

Abstract: A hand-controlled accelerator for automobiles including an inner tubular member formed with a spiral projection on an outer surface thereof and an enlarged base at a lower end thereof, an accelerating cable having an upper end fastened in the base, a brake cable having an upper end fastened in the base, an intermediate tubular member in which is fitted the inner tubular member, a handle having a tubular neck at a lower portion thereof, an outer tubular member in which is fitted the intermediate tubular, and an annular ring-like member having two opposite threaded holes in each of which is arranged a steel ball, a spring having an end bearing against the steel ball, and a screw bearing against another end of the spring, whereby the hand-controlled accelerator for automobiles can prevent the driver from mistakenly depressing the accelerator pedal when desired to apply brake.
