Abstract: An example assembly comprises: a brake shaft comprising gear teeth formed on a circumferential portion of the brake shaft, wherein the brake shaft is substantially constrained from moving in a longitudinal direction along a longitudinal axis of the brake shaft; and a brake gear that is rotatably coupled to a drive shaft of a motor, wherein the brake shaft is rotatable about the longitudinal axis between (i) a first position at which the gear teeth of the brake shaft are disengaged from the brake gear, thereby allowing the brake gear and the drive shaft to rotate, and (ii) a second position at which the gear teeth of the brake shaft engage the brake gear, thereby precluding the brake gear and the drive shaft from rotating due to the brake shaft being constrained from moving in the longitudinal direction.

Abstract: An example brake assembly comprises: a brake disk; an outer brake caliper disposed on a first side of the brake disk; an inner brake caliper disposed on a second side of the brake disk such that the brake disk is interposed between the outer brake caliper and the inner brake caliper; a mounting plate disposed adjacent to the inner brake caliper, wherein the mounting plate is coupled to the inner brake caliper and the outer brake caliper, and wherein the mounting plate comprises a slot; and a brake actuation lever pivotably coupled to the mounting plate and disposed through the slot of the mounting plate to interface with the inner brake caliper, wherein rotation of the brake actuation lever causes the inner brake caliper to move toward the outer brake caliper, thereby squeezing the brake disk between the inner brake caliper and the outer brake caliper.

Abstract: A hydraulic system includes one or more hydraulic subsystems that have a source of additional flow for supplying an auxiliary system. The hydraulic system may include one or more actuator systems, a boost system, and a further hydraulic system, such as a steering system. The source of additional flow for supplying the auxiliary system may include: sizing the boost system for providing both full boost function and auxiliary function, sizing the steering system for providing both full steering function and auxiliary function, utilizing available flow from an unused actuator function, and/or utilizing a selector manifold for actively selecting the source of auxiliary flow based on the flow and pressure demands of the respective hydraulic systems. Such a hydraulic system enables flow to be available to an auxiliary function regardless of the flow requirements for the actuator functions and/or other vehicle functions, while also minimizing interactions and flow disruptions to the various hydraulic subsystems.
