ELECTRONICALLY CONTROLLED PNEUMATIC BRAKE SYSTEM WITH TWO SINGLE-CHANNEL AXLE MODULATORS AND ABS VALVES, AND VEHICLE HAVING A BRAKE SYSTEM OF THIS TYPE
The disclosure relates to an electronically controlled pneumatic brake system for a utility vehicle, including a front-axle brake circuit with a single-channel front-axle modulator for the control of first and second front-axle service brake actuators, wherein first and second front-axle ABS valves are provided; a rear-axle brake circuit with a single-channel rear-axle modulator for the control of first and second rear-axle service brake actuators, wherein first and second rear-axle ABS valves are provided; a braking-value sensor which has an electrical terminal for the provision of an electronic brake demand signal; and a central electronic control unit which receives the electronic brake demand signal and controls the front-axle and rear-axle modulators. Here, it is provided that the central electronic control unit is formed as a structural unit with the rear-axle modulator and/or the front-axle modulator.
ELECTRIC BRAKE DEVICE
An electric brake device has at least three control units: a first diagonal wheel control unit that controls a front-left wheel brake mechanism and a rear-right wheel brake mechanism which are positioned diagonally; a second diagonal wheel control unit that controls a front-right wheel brake mechanism and a rear-left wheel brake mechanism which are positioned diagonally; and a front wheel control unit that controls a front-left wheel brake mechanism and a front-right wheel brake mechanism. Each of the brake mechanisms has a friction-receiving member that rotates together with the wheel; and a friction-applying member that moves while being powered by an electric actuator, and obtains the braking force by pressing the friction-applying member against the friction-receiving member.
CONTROL DEVICE OF BRAKE SYSTEM
A control device of a brake system, according to the present invention, includes, as redundancy, a first control unit for controlling the valve, the motor and the like of a brake system by receiving a sensor unit input, and a second control unit capable of performing the same function as the first control unit when the first control unit malfunctions, and thus the present invention can control the brake system of a vehicle by using the second control unit in an emergency situation in which the first control unit does not normally operate.
Hydraulics Assembly, in Particular for Controlling the Brake Pressure of a Wheel Brake of an Electronically Slip-controllable Brake System of a Motor Vehicle
A hydraulics assembly, in particular for controlling the brake pressure of a wheel brake of an electronically slip-controllable brake system of a motor vehicle, includes a hydraulic block having a recess for receiving a pump element, a line connection for contacting the hydraulics assembly to the wheel brake, channels for providing the pump element with brake fluid, and a hydraulic cavity formed in the interior of the hydraulic block, which cavity is contacted with the recess for the pump element. The cavity includes a riser, which extends from the recess for the pump element in the direction toward the line connection of the hydraulic block and is contacted with the recess for the pump element. The suction line collects gas escaping from the pressure means due to temperature and/or pressure changes and improves the operating noise of the hydraulics assembly.
Hydraulic Block for a Hydraulic Assembly for a Traction Control System of a Hydraulic Vehicle Braking System
Receptacles for a pressure-change damper and for a throttle are provided, at an offset to each other and at an offset to a receptacle for a hydraulic pump, in opposite sides of a hydraulic block for a hydraulic assembly of a traction control system of a hydraulic vehicle braking system, whereby a greater volume of the pressure-change damper and thus better damping are possible.
HYDRAULIC BLOCK OF ELECTRONIC BRAKING DEVICE FOR VEHICLE
A hydraulic block of an electronic braking device for a vehicle includes a first input port and a second input port configured to receive a brake fluid from a main braking system, at least one oil chamber connected to one input port of the first input port and the second input port, a first output port and a second output port configured to discharge the brake fluid to a plurality of wheel brake apparatuses, a first inlet line configured to connect the first input port and the first output port to each other, and a second inlet line configured to connect the second input port and the second output port to each other, a first outlet line bifurcated from the first inlet line, a second outlet line bifurcated from the second inlet line, and a valve mounting unit mounted with a plurality of valves.
Electrical connector for a control unit of a vehicle brake system
An electrical connector is adapted to be retained in a non-conducting housing and electrically connecting a first component to a second component spaced from one another. The connector includes a first end having a first contact portion for electrically communicating with the first component. A second end of the connector has a second contact portion for electrically communicating with the second component. The second end has a cantilevered beam adapted to flex at a knee portion to bias the second contact portion against an electrical contact surface of the second component. An attachment portion is disposed between the first and second ends. The attachment portion includes an engagement portion providing an interference fit with a mating groove of the housing in which the connector is retained.
Hydraulic block for a hydraulic power unit of a hydraulic power vehicle braking system
A cuboidal hydraulic block of a hydraulic power unit of a hydraulic power vehicle braking system for use in a left-hand drive vehicle or a right-hand drive vehicle to be attachable, rotatably by 180° about a horizontal axis, at a splashboard of a motor vehicle. An electric motor of a power brake pressure generator is thus selectively situated on a right or a left side of the hydraulic block.
Piston pump having a helical gear as a power brake pressure generator of a hydraulic vehicle power brake system
A nut of a helical gear of a piston pump of a hydraulic vehicle power brake system. The nut has a plastic body that is covered by a metal sleeve. The plastic body has a through hole having a nut thread.
Electro-hydraulic brake system including isolation valves
An electro-hydraulic brake system comprises a master cylinder block in fluid communication with a reservoir tank containing a brake fluid. The master cylinder block defines a bore and primary and secondary openings. A protrusion extends outwardly from a rear surface of the master cylinder block. A pressure supply unit coupled to a front surface of the master cylinder block and in fluid communication with the reservoir tank for supplying the brake fluid from the reservoir tank. A master cylinder electronic control unit couples to the rear surface and in an abutment relationship with the protrusion. At least one isolation valve disposed on the rear surface, spaced apart from the protrusion and received by the master cylinder electronic control unit, for regulating brake fluid flow from the master cylinder block to the wheel brakes.
