Assignee:

Delphi Technologies, Inc. - Troy MI

International Classification:

B60Q 100

US Classification:

340454, 340452, 3404501

Abstract:

The present invention provides a sensor system for detecting lining wear and fluid level in a dry interface corner actuator for a single wheel brake including a reservoir assembly. The reservoir assembly includes a reservoir for containing fluid for the actuator and a sensor assembly positioned in the reservoir having a single set point to indicate both low reservoir fluid level and a need for brake lining replacement.

International Classification:

B60T 1722

US Classification:

60534, 60545, 92 5 R

Abstract:

A brake master cylinder-sensor system and method are provided. The system includes a master cylinder, a piston slidably positioned in the master cylinder, a magnet positioned on the piston, and a sensor disposed on the master cylinder. A change of piston linear position causes a linear change in a magnetic field position sensed by the sensor, and a brake control signal proportional to the change of piston linear position is generated. A method of operating a brake master cylinder-sensor system includes applying a brake pedal force, changing a piston linear position within a master cylinder, determining a change in a linear magnetic field position proportional to the change of the piston linear position, and generating a brake control signal based on the change in the linear magnetic field position.

US Classification:

60589, 60562

Abstract:

A vehicle braking system master cylinder that can handle pressure pulses within the brake fluid of a vehicle braking system without the destruction of components internal to a master cylinder. A vehicle braking system master cylinder that allows for component subassembly external to the master cylinder and is self-aligning when assembled. Finally, a vehicle braking system master cylinder that allows for variable travel of the primary piston and the secondary piston within the master cylinder and greater fluid flow in the vehicle braking system.

US Classification:

525191, 525240

Abstract:

Disclosed herein is a composition substantially free of polyethylene, wherein the composition includes a thermoplastic material having certain specified mechanical properties, and about 2 wt. % to about 25 wt. % (based on the total weight of the composition) of an olefin mixture that consists essentially of a 30:70 to 70:30 weight ratio of a homogeneous ethylene-alpha olefin interpolymer and a propylene-based elastomer having at least 75 wt. % units derived from propylene and about 10 wt. % to about 25 wt. % units derived from a Cor a Calpha olefin. The specified olefin mixture unexpectedly imparts to the overall composition mechanical properties (such as impact strength, for example) heretofore unattainable. These mechanical properties can be expected to be tailored to suit the end-use expected of the composition.

International Classification:

B60T013/74

US Classification:

303/003000

Abstract:

A brake pedal feel emulator that produces a pedal characteristic not unlike conventional vacuum boosted or hydraulic brake systems. The system includes a master cylinder, a first and second piston slidably carried in the master cylinder, a gas-filled bellows emulator and a spring emulator operably attached to the master cylinder, and a reservoir carrier near the master cylinder. When a brake force is manually applied, a gas within gas-filled bellows compresses thereby generating a first stage of emulator travel. Once a pre-load force is surpassed, a coil spring within the spring emulator compresses thereby generating, along with the gas-filled bellows, a second stage of emulator travel. The two stages of emulator travel comprise a characteristic rate of pedal travel versus pedal force.
