A brake lock system for a pumpjack brake apparatus comprises a latch handle lever pivotally mounted at a location on a pumpjack, a countershaft rotatably mounted on the pumpjack, latch handle linkage, and control linkage that transitions movement and force of the latch handle lever to a latch arm with a latch dog for pivoting the latch arm to insert the latch dog in a notch in the pumpjack brake apparatus. The latch handle, latch handle linkage, control linkage, and latch arm have dimensions that provide a mechanical advantage of the latch handle lever over the latch arm.

Detectable indicia are provided on the interior circumferential rim of the brake hub-drum adjacent to, and spaced apart from, the backing plate of the brake. A sensor is mounted on the backing plate to detect wheel speed and/or other operating conditions detectable from the motion and/or relative location or condition of those indicia. The number of indicia used and the indicia spacing along the interior circumferential rim is selected as needed for a given type of sensor and/or a given application. In the case of a speed sensor, the indicia can be a series of notches in the rim along the entire interior circumferential rim, resembling a series of teeth into that rim. The width of those teeth can be formed wide enough to accommodate movement of the hub-drum relative to the backing plate and/or the sensor, without loss of system functionality, according to the sensing tolerances of a given sensor being used in a given application.

A device for manually and/or electromotively adjusting or securing a first vehicle part and a second vehicle part relative to each other is provided. The device comprising an adjustment part which has a joint for pivotable arrangement on the first vehicle part, wherein the adjustment part is to be arranged on the first vehicle part in such a manner that, when the vehicle parts are adjusted relative to each other, the adjustment part moves relative to the second vehicle part, an output element which is to be arranged on the second vehicle part, is operatively connected to the adjustment part and is drivable in order to move the adjustment part relative to the second vehicle part, a shaft connected to the output element, and a flexible force transmission element which is fastened at a first end and at a second end to the adjustment part.

The present invention relates to a mechanical energy transfer system that comprises a moving member that imparts energy to an engaging member as a friction force is applied to the moving member. The moving members may be rotating plates/disks, belts, or drums/cylinders. Upon engagement of the moving members by the engaging members, movement is transferred to the engaging members. Movement transfer may occur through the application of any frictional force, such as a magnetic force or a mechanical force.

What is disclosed is a self governing speed control device for controlling the rotation speed of a sprinkler turbine. The device has a housing that houses a viscous fluid. An axle extends into the housing and is configured to rotate in the housing. The axle is fixedly attached to a primary drum that rotates with the axle. One or more hinge pins extends from the primary drum. A brake shoe is positioned on the hinge pin. The hinge pin passes into a slot in an actuation drum configured to rotate on the axle. The brake shoe is configured to expand and contract based on the speed of rotation of the axle in relation to the speed of rotation of the actuation drum.

A drum brake apparatus is provided for a vehicle air braking system. The drum brake apparatus comprises a wheel drum having a first interior chamber. The drum brake apparatus also comprises a drum brake assembly disposed in the first interior chamber of the wheel drum and mounted on inboard side of the wheel drum. The drum apparatus further comprises a brake drum adapter mounted on outboard side of the wheel drum and providing a second interior chamber in which an electric drive motor can be disposed. The drum brake apparatus also comprises a wheel hub disposed in the second interior chamber of the brake drum adapter and to which a wheel rim can be mounted.

A brake assembly having a non-braking configuration and a braking configuration includes a brake shoe having a brake lining coupled thereto. An actuator is coupled to the brake shoe, the actuator movable along an actuation path between a neutral actuator position and a braking actuator position. An actuator distance between the neutral actuator position and the braking actuator position increases over time in response to a reduction in thickness of a brake lining installed on the brake shoe. Moving the actuator from the neutral actuator position to the braking actuator position past a predetermined actuation distance causes a ratchet mechanism to advance to a next sequential ratchet position, which in turn moves the neutral actuator position of the actuator a predetermined distance away from the minimum actuator position. A sensor is coupled to the ratchet mechanism for detecting the sequential ratchet position of the ratchet mechanism.

An omni-wheel may include a shaft, a plurality of rollers, and a braking device. The plurality of rollers may be circumferentially arranged about the shaft and arranged radially outward from the shaft. The braking device may include a fluid-filled bladder and a plurality of braking pads. The fluid-filled bladder may be circumferentially arranged about the shaft. The plurality of braking pads may be arranged between the fluid-filled bladder and the plurality of rollers. The fluid-filled bladder may expand radially outward when pressurized, displacing the plurality of braking pads radially outward to contact the plurality of rollers, preventing rotation of the rollers.
