摘要： A combination hydraulic master cylinder comprising two typically parallel pumps disposed within adjacent compartments within a common body of the combination hydraulic master cylinder. Each pump's piston physically pressurizes hydraulic fluid that has been separately drawn into its respective cylinder and in hydraulic isolation, however the proximate location of the independent pumps allows for convenient operation using one hand on one handlebar with reduced congestion of space rather than the more conventional arrangement of two separate master cylinders. The pistons are actuated mechanically using dedicated levers mounted externally to the cylinders. The levers are adjustable in the manner to which they are disposed to the pistons. One lever is oriented such that it is operable using a finger pull action; the second lever is oriented such that it is operable using a thumb push action.

摘要： A brake system for hydraulically actuating a pair of front wheel brakes and a pair of rear wheel brakes includes a reservoir and a master cylinder fluidly connected to the reservoir and operable to provide a brake signal. A first power transmission unit is in fluid communication with the reservoir, a selected one of the rear wheel brakes, and a first fluid separator corresponding to a selected one of the front wheel brakes. A first electronic control unit is configured to control the first power transmission unit. A second power transmission unit is in fluid communication with the reservoir, the other one of the front wheel brakes, and a second fluid separator corresponding to an other one of the front wheel brakes. A second electronic control unit is configured to control the second power transmission unit.

摘要： A brake control system and method for autonomous vehicle control that includes a first brake pedal connected to a first brake arm, the first brake arm is connected to a first brake shaft, the first brake shaft extends a length between an upper end and lower end and includes a first actuator that expands and contracts in length. The lower end of the first brake shaft is operably connected to a first brake mechanism. An autonomous control system having a controller with microprocessor, memory and instructions is connected and controls operation of the first actuator. When the first brake shaft expands in length the first brake mechanism is engaged by the lower end of the first brake shaft thereby applying the brakes. The first brake mechanism is operable by depressing the first brake pedal in manual operation mode as well as by controlling the first actuator in autonomous operation mode.

摘要： A hydraulic assembly for generating brake pressure for a hydraulic brake system, comprising a housing which is produced from a cast blank, having at least one receiving cavity for receiving a connector piece which is connected to a fluid container and which can be plugged along a plug-in axis (S) into the receiving cavity. The cast blank has, in the receiving cavity, at least one substantially planar surface, the normal vector (N) of which is oriented at an oblique inclination angle (W) with respect to the plug-in axis (S).

摘要： A braking device for a hydraulic motor vehicle braking system having an electromechanically driven booster stage and a ball screw drive. In order to provide a braking device which is of particularly compact, cost-effective and weight-saving construction and has short pedal strokes, and an easily adjustable pedal characteristic curve, at the same time enabling effective direct action in case of failure of the booster stage and comfortable haptic feedback at the pedal during normal operation, the actuating force from a piston rod is introduced into the spindle, wherein the piston rod can be moved axially to a limited extent relative to the spindle and a spring element is inserted in the flow of force of the actuating force between the piston rod and the spindle, which spring is compressed axially when the actuating force is introduced.

摘要： A master cylinder is described. The master cylinder includes a chamber delimited by a piston and supplied from a brake fluid reservoir installed on the top of the master cylinder by an end fitting engaged in a nozzle on the body of the master cylinder. The piston has a nose of reduced section upstream of its skirt guided in the bore hole of the master cylinder and the nozzle is connected to the chamber by a drill hole issuing into the chamber at least partly upstream of the piston in rest position. A valve module is installed in the drill hole to manage communication between the reservoir and the chamber as a function of the position of the piston and the pressure in the chamber with respect to the pressure in the reservoir.

摘要： A brake system has a wheel brake and is operable under a non-failure normal braking mode and a manual push-through mode. The system includes a master cylinder operable by a brake pedal during a manual push-through mode to provide fluid flow at an output for actuating the wheel brake. A first source of pressurized fluid provides fluid pressure for actuating the wheel brake under a normal braking mode. A second source of pressurized fluid generates brake actuating pressure for actuating the wheel brake under the manual push-through mode.

摘要： A master brake cylinder includes a unique mounting arrangement for securing thereof to a firewall of a vehicle and a particular porting arrangement. A cylinder sleeve includes a series of ports that cooperate with movement of the piston allowing for by-passing of the piston at one end position and then movement of the piston past the ports for brake actuation. Additionally a two stage pressure intensifier is provided that is in-line between a master brake cylinder and brake pistons. The intensifier also includes a by-pass position at one end of the movable piston having a differential area between a forward and a rear face of the piston.

摘要： The disclosure relates to a main brake cylinder arrangement for a motor vehicle brake system, comprising: at least one piston, which can be displaced along a displacement axis (V) and, together with a housing arrangement, delimits a pressure chamber; a force input member, which is displaceable according to a brake pedal actuation and is coupled or can be coupled to the piston for common displacement; an elongated position encoder element, which is displaceable according to an actuation of the force input member; a detection unit, which is designed to detect a displacement of the position encoder element; and a receiving region, which is designed to receive the position encoder element at least in part. The ends of the position encoder element are each arranged in a different housing region (F, S), which is arranged in a fluid path between the first and second housing region (F, S).
