Apparatus including a brake control assembly having a brake fluid accumulator assembly. The brake fluid accumulator assembly includes a brake fluid orifice, at least one brake-fluid-accumulating piston bore, a controllable bi-directional motor, and at least one piston. The brake fluid orifice is fluidly connectable to a brake apply master cylinder and is fluidly connectable to a wheel brake. The at-least-one brake-fluid-accumulating piston bore is fluidly connected to the brake fluid orifice. The motor has a first motor driving direction and an opposite second motor driving direction. The at-least-one piston is each positioned in and slidable within a corresponding brake-fluid-accumulating piston bore and is each movable by the motor, in the first motor driving direction, to move in compression within the corresponding brake-fluid-accumulating piston bore.

A compact controlled braking system including a hydraulic control unit having a first housing and a motor positioned within the first housing and an electronic control unit connected to the hydraulic control unit, the electronic control unit having a second housing, wherein at least a portion of the motor is received within the second housing.

Compact controlled braking system

An apparatus and method are provided for operating a pump-less rear wheel anti-lock brake system of a vehicle using speed sensors on at least one front and one rear wheel, to provide a true dynamic rear proportioning (DRP) function, and to significantly enhance braking performance in rear wheel anti-lock mode through better management of the volume of pressurized fluid supplied by the master cylinder using rear pressure control (RPC).

Rear pressure control and dynamic rear proportioning in a vehicle brake system

An electro-hydraulic brake system containing four isolation piston assemblies each of which is comprised of a cylinder, a piston, and a pair of hydraulic lines. The cylinder has only two apertures, and the piston is disposed in the cylinder. The first hydraulic line communicates between a wheel brake and a first side of the piston through one of the apertures. The second hydraulic line communicates between an accumulator and a second side of the piston through the other of the apertures. The system components are arranged in a compact, easy to manufacture package.

Electro-hydraulic braking system having isolation pistons

Master cylinder pressure of either or both of the primary and secondary braking circuits is sensed by a pressure sensor or sensors mounted in a manifold which is installed directly on a brake pressure modulator housing when the modulator is manufactured. The pressure sensors receive power and are grounded through the electronic control unit which is an integral component of the modulator; accordingly, the sensors do not require external electrical connections other than those already provided on the modulator. Since the sensing manifold is installed and tested for leaks when the modulator is manufactured and before the modulator is shipped to the vehicle assembly plant, assembly operations in addition to those required in installation of the modulator in the vehicle braking system are not required.

Brake pressure modulator with pressure sensor manifold

A solenoid coil attachment mechanism includes a coil assembly with a wire end that projects from the coil assembly and an extending elongated leg that includes a latching mechanism. A carrier has a wall with an opening receiving the leg of the coil assembly and has a wire guide that is funnel shaped, has an open end and receives the end of the wire. A circuit board is attached to the carrier and the wire end is soldered directly to the circuit board.

Solenoid coil attachment mechanism

A solenoid actuated valve includes a first subassembly that carries a coil having its terminal pins attached to a structure such as a circuit board or lead frame. A second subassembly is provided for mating with the first subassembly and carries the valve body. The first subassembly has a solenoid spool including the coil, and a case surrounding the spool. An end plate is suitably locked to the case. A bias spring is provided between the spool and the end of the case. The spool assembly is designed to be freely floating both radially and axially within the coil case and end plate, as restricted by the bias spring. This permits proper location of the coil case to the hydraulic valve body assembly.

Solenoid coil positioning assembly

A single shear joint is provided which includes a conical ferrule establishing a nesting means of engagement with controlled embedment between a link and a mating component.

A drum brake is provided which in a preferred embodiment includes a backing plate having an anchor at a first end, first and second brake shoes pivotally mounted with respect to the anchor, a nonrotative nut mounted for linear motion with respect to the backing plate, a first apply lever pivotally mounted with respect to the nut and with respect to the first brake shoe, a second apply lever pivotally mounted with respect to the backing plate and with respect to the secondary brake shoe, a first strut pivotally mounted with the first and second brake shoes, a power screw threadably engaged with the nut for translating the nut, and an electric motor torsionally associated with the power screw for turning the same.

Electric drum brake

A vehicle braking actuated traction control system is provided which includes a bored frame fluidly connected with a master cylinder and a wheel brake. A spring biased plunger with a sealing head slidably mounted within the bore isolates the bore from the master cylinder by axial movement of the plunger in a first direction. A piston operatively associated with the plunger is sealably slidably mounted within the bore for creating a variable control volume in the bore in fluid communication with the wheel brake. The piston is connected with the plunger via a spring which biases the plunger away from the piston. A nut is fixably connected with the piston and a drive screw threadably engaged with the piston is reversibly powered by an electric motor which is responsive to the signals given by a controller which is cognizant of a vehicle wheel condition. Upon the appropriate signal the drive screw will power the piston to a position to cause the plunger to isolate the wheel brake from the master cylinder and thereafter modulate the pressure within the wheel brake as commanded by the controller during a traction control cycle.

Traction control modulator

An integrated anti-lock braking (ABS)/traction control (TC) braking system is provided which includes a controller cognizant of a rotational condition of a wheel, a master cylinder, an actuator with a bore, the bore having a first fluid connection with a master cylinder and space therefrom a second fluid connection with a brake, a first normally open solenoid valve for isolating the master cylinder from the wheel brake when the controller places the system in an ABS or TC mode, and a hollow primary piston mounted within the bore along first, second and third spaced sealed peripheries having a first port connecting the interior of the primary piston with its exterior between the first and second sealed peripheries and communicating with the second fluid connection of the bore. The primary piston also has a second port fluidly connecting an end of the primary piston most adjacent to the bore first fluid connection with the interior of the primary piston and the primary piston having a check valve mounted within the second port and the primary piston has a third sealed periphery generally adjacent the bore first fluid connection. A secondary piston is mounted within the primary piston movable in a direction towards the bore first fluid connection to pressurize the brake and movable in an opposite direction to release the pressure within the brake, the secondary piston has an extreme position with respect to the primary piston wherein the secondary piston opens the check valve and further movement of the secondary piston causes the pistons to move in unison pressurizing the wheel brake. A reversible motor connected with a gear train, drive screw and nut moves the secondary piston in response to signal give by the controller.

Integral ABS and traction control having an electric modulator

A fishing pole holder is provided and consists of a bracket attached to an elongated post having a pointed end adapted to be inserted into the ground near a body of water so that a portion of a fishing pole can be inserted and supported between the bracket and the post. A built-in flashlight is carried by the post for illuminating for night fishing. A mechanism carried on the post can visually indicate a hooked fish by flashing the flashlight when the fish pulls the fishing pole.
