Abstract:
An accelerator module actuated by the driver's foot for controlling the output of a driving engine or motor of a motor vehicle employs a friction element for generating a friction hysteresis for the purpose of achieving a comfortable driving feel. Support of the pedal lever is completely independent of the generation of the friction hysteresis, resulting in a particularly favorable, especially stable, and play-free support of the pedal lever, and the brake insert for generating the friction hysteresis is particularly easy to manufacture.
Abstract:
The present invention is a two-piece bicycle crank set comprising of two monolithic, thin-wall continuous tubular members. Each tubular member includes a crank arm and a one-half portion of a crank axle, where the crank arm and the portion of the crank axle form a continuous thin-wall tubular shape. The two tubular members are coupled precisely midway between two bearing sets within a bracket shell of a bicycle. The coupling connecting the two tubular members can include an outer sleeve, an inner sleeve, two exteriorly tapered and internally threaded bushings and a threaded stud. Turning the threaded stud positions the bushings to expand the inner sleeve, whereby the crank axle portions of the two tubular members are secured within the inner sleeve and the outer sleeve by the expanding inner sleeve. Alternatively, an interference fit coupling connects the two tubular members, and includes a mortise member and a tenon member. The tenon member fits into and interlocks within the mortise member to secure the first tubular member to the second tubular member. The interference fit coupling can further include an attachment bolt and a separation bolt to facilitate assembly and disassembly of the coupling.
Abstract:
An adjustable brake and throttle pedal assembly for a vehicle which includes a throttle pedal arm and support arm pivotally mounted to a bracket. An electronic throttle control unit is mounted to the bracket at the pivot point of the pedal arm assembly. A first adjustment drive mechanism extends in a space formed between the support arm and throttle pedal arm. The adjustable brake and throttle pedal assembly also includes a brake pedal arm mounted to the bracket. A second adjustment mechanism is operatively attached to the brake pedal arm. The second adjustment mechanism is operatively connected to the first adjustment mechanism, to cooperatively position the throttle pedal arm and the brake pedal arm at a selected position between a retracted position and an extended position.
Abstract:
A bicycle crank arm apparatus includes an axle having a first end portion and a second end portion, wherein the first end portion has an outer peripheral surface and a threaded inner peripheral surface; an axle bolt having a threaded outer peripheral surface screwed into the threaded inner peripheral surface of the first end portion of the axle; a crank arm having an axle mounting boss defining an opening for receiving the first end portion of the axle therein, wherein the axle mounting boss includes a first fastener for tightening the axle mounting boss around the first end portion of the axle; and wherein the crank arm boss is positioned axially inwardly of the axle bolt.
Abstract:
An adjustable control pedal for a motor vehicle includes an upper arm, a lower arm supported by the upper arm and operatively connected to the upper arm for selected movement relative to the upper arm, and a drive assembly operatively connected to the lower arm to selectively move the lower arm relative to the upper arm. A hall-effect sensor is located adjacent a drive screw and cooperates with a ring magnet rotatable with the drive screw to detect motion information. A controller receives the motion information and activates an electric motor upon initialization of the controller to move the lower pedal arm in a first direction until a first mechanical stop is engaged and establish a home stop position and to move the lower pedal arm in the other direction until a second mechanical stop is engaged and establish a travel stop position.
Abstract:
A device for the electromotive regulation of an actuating device of an automotive vehicle including an electromotive adjusting device for at least one actuating member and a control unit that is electrically connected thereto, which, in turn, is connected to electric switching device, and that at least one actuation detection means that is connected electrically to the control unit is provided to monitor an actuation of the actuating member so that in the case of a safety-critical condition an electric signal which locks the electromotive regulation can be sent from the control unit, or the energization of the electromotive adjusting device can be interrupted. The present invention prevents an electromotive regulation to take place at an inappropriate time, that means during safety-critical conditions, e.g., during a brake application or when the vehicle is moving.
Abstract:
A locationally adjustable actuator is provided having a force input to a rod operatively associated with an automotive vehicle control. The actuator includes two parallelogram linkages which link an actuator pedal to a rod link which is pivotally connected with a rod which provides an automotive vehicle control input. The parallelogram arrangement is furthermore connected with a slider which is linearly adjustable with respect to the vehicle. Movement of the slider causes the actuator pedal to be linearly adjusted.
Abstract:
A release arrangement for a hydraulically actuated clutch in a motor vehicle has an energy accumulator connected with a hydraulic system. The energy accumulator is connected with a pedal via a kinematic arrangement which adapts the pedal forces to the pedal path. It is possible to adapt the boosting force characteristic to the required pedal force curve in a very precise manner. This leads to a boosting force that possibly increases the depressing force, but primarily increases the force in the boosting area following the dead center of the kinematic arrangement. The characteristic of the boosting force curve over the pedal path can be adapted to the respective operating system in the motor vehicle without major structural alterations.
Abstract:
A method and system for providing vehicle control to a driver utilizes an accelerator pedal position and other various inputs. A powertrain control module uses the accelerator pedal position and the other various inputs to give the driver a combination of speed and torque control. In operating a vehicle at speeds ranging from zero to forty-five miles per hour, the powertrain controller provides the driver with torque control by mapping pedal position to electronic throttle angle according to a plurality of predetermined acceleration functions. In operating the vehicle at speeds greater than forty-five miles per hour, the powertrain controller provides the driver with speed control by mapping the electronic throttle angle according to a plurality of predetermined speed functions. Upon receiving other various inputs, the powertrain controller switches control from one form to the other.
Abstract:
A brake pedal mechanism (4) for motor vehicles with a pedal block(5), which is fastened to the body of the motor vehicle and accommodates a mount (18) for the pivot axis (17) of a rotatably mounted actuating pedal (6).
