Electronic Parachute Deployment System
An electronic parachute deployment system includes an electronic actuator, a control module, a deployment actuator, and a release mechanism. A parachute is positioned on a payload device, such as a racecar, to slow or stop the payload upon receipt of an electronic deployment activation signal. The electronic deployment signal is verified, including determining proper voltage and source. The deployment system includes multiple redundancies including mechanical deployment redundancy, remote deployment redundancy, and power supply redundancy. The control module responsible for monitoring deployment includes indicators and sensors to indicate a status, operation, or mode relative to the operability of the payload device, relative to components of the release mechanism, and relative to the parachute deployment.
SYSTEM AND METHOD OF BRAKING FOR A PATIENT SUPPORT APPARATUS
A patient support apparatus includes a base having a length and including a plurality of caster wheels enabling movement of the patient support apparatus across a floor surface. An auxiliary wheel support structure is secured to the base and rotatably supports at least one non-castered auxiliary wheel. A drive mechanism including a motor may be configured to drive the auxiliary wheel. A braking system including at least one brake member may be configured to apply a braking force to decelerate the auxiliary wheel and is movable between a first position wherein the at least one brake member is disengaged from the auxiliary wheel and a deployed position wherein the at least one brake member is frictionally engaged with the auxiliary wheel to restrict rotation of the auxiliary wheel. The braking system may be configured to synchronize the braking forces applied to first and second auxiliary wheels.
WORK VEHICLE
A work vehicle includes a parking brake lever, right and left braking arms, and an intermediate link mechanism configured to couple the parking brake lever and each of the braking arms. The intermediate link mechanism includes a support shaft configured to rotate, left and right coupling units that are coupled to the support shaft and configured to rotate each of the braking arms in response to a rotational movement of the support shaft, and a cable mechanism having a control cable. The cable mechanism is configured to rotate the support shaft via the control cable in response to a rotational movement of the parking brake lever.
Cable routing system of bicycle and stem thereof
A cable routing system of a bicycle, including a stem having a receiving space and an engaging hole communicating with the receiving space, a frame, a fork, an expander, and at least one cable. A head tube of the frame has a top portion having an upper mounting hole and a bottom portion having a lower mounting hole. The fork sequentially passes through the lower mounting hole, the upper mounting hole, and the engaging hole to be connected to the stem. The expander is disposed in a steering tube of the fork and has at least one cable passage communicating with the receiving space and the engaging hole. The cable extends into the steering tube from outside by passing through the receiving space and the cable passage. An end of the cable is connected to a bicycle controller, and another end thereof is connected to a bicycle component.
Linear actuator
Linear actuator comprising an electric motor (2) which through a transmission (3) drives a spindle unit, where the spindle unit comprises at least one spindle (4) with a spindle nut (5), where the spindle (4) is equipped with a bearing (8). In connection with the spindle unit there is an adjustment element (6), typically tubular. In order to retain the adjustment element (6) in a given position when the power supply for the electric motor (2) is interrupted, a brake (11) comprising a spring (15) and a cylindrical element (12) is provided. The cylindrical element (12) has a threaded pin (12a) on which a nut (13) is arranged, and where the spring (15) is positioned around the cylindrical element (12) between one side of the nut (12) and a stop (14) on the cylindrical element (12) such that the spring (15) presses the nut (13) with its other side against a contact surface (16). The brake power is thus generated by the nut rubbing against the contact surface with its one side. It is thus an alternative brake construction having a simple construction and where the spring only exerts a compressive force. The brake power can be adjusted to the spring power, and the friction between the nut and the contact surface and finally the thread pitch on the nut.
SYNCHRONOUS BRAKING DEVICE FOR FRONT AND REAR WHEELS OF BICYCLES
A synchronous braking device for front and rear wheels of bicycles is revealed. A left brake cable and a right brake cable which are operated by a left brake lever and a right brake lever respectively are connected to a synchronous driving integration mechanism. No matter users squeeze the left brake lever, the right brake lever, or both the left and the right brake levers at the same time, a front brake cable and a rear brake cable are driven synchronously. Thereby a brake installed on a front wheel and a brake set on a rear wheel are further driven to brake at the same time. Thereby the rider's safety during riding is ensured.
CABLE-COUPLED BY-WIRE CONTROL SYSTEM
A cable-coupled by-wire control of a vehicle control function traditionally activated by driver manipulation of a pedal is achieved though the agency of a Bowden cable having a first end fastened to the driver pedal, and a second end coupled to a by-wire actuator. The by-wire actuator has a pulley on which the second end of the cable is fastened, an electric motor coupled to the pulley to permit by-wire activation of the vehicle control function by rotation of the pulley in a direction to pull on the pedal with the cable. A relief chamber of the actuator radially outboard of the pulley accommodates slack in the cable within the actuator caused by driver manipulation of the pedal during by-wire activation of the control function.
Lawn Care Vehicle Brake System with Improved Brake Cable Actuation
A riding lawn care vehicle (10) includes first and second drive wheels (32), a steering lever (34), a brake assembly (110), and a mechanical brake linkage assembly (120) including a cable tensioner (250). The brake assembly (110) may be operably coupled to at least one of the first and second drive wheels (32) to enable brakes to be selectively applied to the first and second drive wheels (32) based on a position of the steering lever (34). The cable tensioner (250) may be configured to activate the brake assembly (110) relative to the at least one of the first and second drive wheels (32) in response to the steering lever (34) being moved outwardly to an outboard position. The mechanical linkage assembly (120) may be configured to provide a greater amount of rotation of the cable tensioner (250) than a magnitude of rotation of the steering lever (34) when the steering lever (34) is moved from the inboard position to the outboard position.
Parking brake unit of double hinge type
The present invention relates to a double hinge type parking brake device which is constituted by a plurality of connection members having each gear formed on an outer peripheral surface while excluding a connection cable connecting a parking brake lever and a parking cable operating shaft for operating a parking cable to maintain an initial installation state instead of stretching the connection cable when the connection cable is used for a long time, thereby facilitating post management.
