Abstract: The brake control apparatus sets a target deceleration (1) in accordance with an amount of operation of the brake pedal. It calculates another target deceleration (2) on the basis of the target deceleration (1). In this calculation, limit values of deceleration increasing and decreasing gradients with respect to the target deceleration (1) are set on the basis of the target deceleration (1), and then the target deceleration (2) is obtained by correcting the target deceleration (1) on the basis of the established deceleration increasing and decreasing gradients. Accordingly, the deceleration increasing/decreasing gradient becomes small when braking is gentle. This makes it possible to curb an abrupt change in brake force to achieve smooth brake control. Further, the deceleration increasing/decreasing gradient becomes larger when braking is abrupt. Accordingly, it is possible to create a great change in brake force to provide a high response.

Abstract: A control system for controlling a brake system of a braked vehicle during a turn, the vehicle having four wheels. The control system is configured to selectively modify a brake pressure applied to each of the wheels by the brake system. The control system is configured to receive a driver input relating to a brake pressure sought to be applied. The control system includes a controller for monitoring a slip status of each of the four wheels during a turn. The controller is configured to direct the brake system to independently increase, decrease, or hold the brake pressure applied to each of the four wheels based at least in part upon slip status of each respective wheel. The controller is configured to direct the brake system to modify the brake pressure applied to each of the wheels such that the brake pressure applied to a given wheel of the four wheels is always equal to or less than the brake pressure sought to be applied.

Abstract: A column unit includes a fixed upright tube with a bottom upright-tube end and a top upright-tube end and a telescopic tube axially displaceably guided in the upright tube. A cylinder of a pneumatic spring is axially displaceably guided in the telescopic tube. A piston rod projecting out of the cylinder of the pneumatic spring has a free end fastened on the upright tube proximate the bottom upright-tube end. A carry-along stop of the cylinder of the pneumatic spring allows the telescopic tube to be carried along out of the upright tube when the pneumatic spring is moved axially. A securing element limits an axial movement of the telescopic tube out of the upright tube. The securing element is arranged on the upright tube and abuts the outer cylindrical lateral surface of the telescopic tube with radially inwardly directed resilient prestressing.

Abstract: A vibration damper includes a damping element and a pneumatic spring, where the damping element has a container tube, a fastening part, and a piston rod, and where the pneumatic spring consists of a spring bellows acting as a roll bellows, an outer tube connected to the mass whose vibrations are to be minimized, and a roll-over tube carrying a roll-over profile. The spring bellows forms one boundary of an elastic space filled with a pressurized gas, whereas the roll-over tube seals off the gas space from the container tube and is attached thereto. A stamped and formed support ring, which supports the roll-over tube on the container tube and serves to suppress tilting movements, is installed between the container tube and the roll-over tube.

The cable disengagement prevention configuration allows a cable end fitting (28) to pass through a gap between the brake lever (18) and the brake shoe (11) only when rotating the brake lever (18).

Abstract: A motor-driven disk brake having a caliper containing a piston for pressing a brake pad, a rotary actuator and a rotary-to-rectilinear motion converting mechanism for transmitting rotation of the rotary actuator to the piston after converting it into rectilinear motion. The piston is driven in response to rotation of the rotary actuator to press the brake pad against a disk rotor, thereby generating braking force.

The brake releasing mechanism has an urging device for generating a torque in the direction for returning the piston in response to the rotation of the rotating member in the direction for advancing the piston.

Abstract: A wheel bearing assembly is provided which can suppress brake judder. A film is disposed between the brake rotor-mounting surface of the wheel mounting flange and an abutment surface of a brake rotor to fill a gap therebetween to suppress the deformation of the brake rotor. Also, by concentrating the contact force between the wheel-mounting flange and the brake rotor when a disc wheel of the wheel is tightened to the hub bolts to a portion near the hub bolts, the contact between the wheel-mounting flange and the brake rotor on the surfaces between the hub bolts is suppressed so that undulation of the flat surfaces between the hub bolts will not cause deformation of the brake rotor.

The auxiliary vibration-damping member has a constricted portion formed at a longitudinal central portion thereof and having a smaller cross-section than any other part of the auxiliary vibration-damping member.

Abstract: An improved airspring assembly includes a collapsible support member disposed within the pressurizable chamber of an airspring having a flexible sidewall. The support member is configured such that it extends and collapses along a longitudinal axis of the chamber responsive to pressurization and depressurization of the chamber, respectively. The support member also is configured such that it retains a substantially rigid outer perimeter, thereby restricting movement of the chamber's flexible sidewall toward the longitudinal axis when the chamber is depressurized. The support member also is configured such that it does not interfere with the full stroke of the airspring.

Abstract: In a method for regulating the driving stability of a vehicle pressures for individual brakes of the vehicle are determined in dependence on several input quantities so that the driving stability is enhanced by brake interventions at individual wheels. To enhance the driving stability of a vehicle, it is determined during stable driving performance whether in view of a highly dynamic steering maneuver there is a tendency to a subsequent unstable driving performance, and in this case brake pre-intervention will occur already when the vehicle exhibits a stable driving performance.

Abstract: An impact absorber for a vehicle includes an outer body including a cavity having an axis, and an inner body situated partially within the cavity for relative movement into the cavity when the absorber is subjected to an impact. The inner body has at least one lateral protrusion. A number of deformable units are located in the outer body at different positions along the cavity. The deformable units partially protrude into the cavity for successive engagements and deformations, one unit after another unit, along the cavity, by the protrusion of the inner body moving into the outer body, thereby absorbing the energy of an impact in different stages. Each deformable unit includes a rigid ball protruding into the cavity and a deformable plate fixed behind the ball.
