摘要： A brake booster provides additional boost capacity without unduly increasing booster size and weight by providing a vacuum pump connected so as to add its additional vacuum capacity to that of the normal vacuum source when activated in response to sensed approaching run-out. The additional vacuum is provided by connecting the vacuum pump in a second conduit between the vacuum source and the booster vacuum chamber in parallel with a first conduit connecting the vacuum source directly with the booster vacuum chamber, with check valve means in the first and second conduits preventing substantial vacuum loss from the vacuum chamber. Approaching run-out is signaled by a sensor responsive to a vacuum level in the working chamber; and control means are responsive to a predetermined low value of the sensed vacuum level in the working chamber to activate the vacuum pump and thus increase the vacuum level in the vacuum chamber over that produced by the vacuum source, whereby a greater pressure differential is available across the booster diaphragm before run-out is encountered. An optional sensor responsive to vacuum level in the vacuum chamber enables the vacuum pump to be additionally used for backup of the vacuum source while still providing the functionality of the invention in most cases. The venting of the vacuum pump to the vacuum source reduces released noise which might otherwise require bulky noise filter apparatus.

摘要： A vacuum booster for a vehicle brake system provides a working pressure valve seat on a valve member axially movable with respect to an input member. A rotary electric motor within the booster has an output shaft coupled through rotary to linear motion conversion apparatus to move the valve member with its working pressure valve seat relative to the input member. The combination of elements is designed as a drop-in replacement for a standard air valve member. The motion conversion apparatus provides much greater mechanical force than a linear solenoid; and this allows a more straightforward design of the valve arrangement, particularly the use of a high friction seal such as a simple "O"-ring in a groove. In further contrast to a linear solenoid, it further provides positive control of the working pressure valve seat position and an extended range of travel with constant force throughout the range. A magnet may be mounted on the nut adjacent a stationary magnetic sensor mounted on a circuit board associated with the motor to provide a signal of the position of the nut for the accurate positioning of the working fluid valve seat. A retaining clip normally used to prevent axial withdrawal of the input member from the power piston may be advantageously used to circumferentially engage an extension of a portion of the input member to prevent its rotation.

摘要： A variable pitch screw driver system includes a rotatable drive nut powered by a motor actuator. A base screw having a fixed pitch extends through the drive nut and is linearly translatable in response to rotation of the drive nut. The base screw carries a pin that follows a secondary helical screw. Linear translation of the base screw is altered by tracking of the pin along the helical screw such that rotation of the base screw is selectively effected simultaneously with rotation of the drive nut resulting in an effective variable pitch of the screw driver. Linear translation of the base screw effects linear translation of a piston at a variable rate.

摘要： A single-operation valve assembly useful in such braking system applications, as well as others, includes a flow passage and a valve member located within the flow passage at a first position in which the valve member prevents fluid flow from an upstream side of the valve member to a downstream side of the valve member. The valve member and flow passage are configured for movement of the valve member from the first position along the flow passage to a second position along the flow passage when a pressure difference between the upstream side of the valve member and the downstream side of the valve member exceeds a threshold level. The valve member and the flow passage are also configured for free flow of fluid along the flow passage in either direction when the valve member moves to the second position. Thus, in a braking system circuit the subject valve assembly does not interfere with fluid flow in the circuit after the valve member has been blown to the second position.

摘要： The invention provides an electric brake caliper that includes a caliper housing have a rotor channel adapted to receive a rotor therein, where the rotor channel has a first axial surface adapted to seat an outer brake pad thereon. The brake caliper also includes a piston assembly mounted to the housing on an axial side of the rotor channel opposite that of the outer brake pad. The piston assembly includes: (a) a piston nut, reciprocatable towards and away from the rotor channel, where the piston nut is adapted to seat an inner brake pad thereon, (b) a cylindrical screw threaded into the piston nut, where the screw includes a coaxial, cylindrical bore extending therein, and (c) a planetary gear train positioned within the cylindrical bore of the screw, where the planetary gear train includes a motor-driven, central sun gear, at least one coaxial tube ring gear and at least one planetary pinion operatively engaged between the sun gear and the tube ring gear and carried on a revolving carrier, where the revolving carrier includes an output shaft extending therefrom, coaxial with, and coupled to the screw. The planetary pinion is axially slidable with respect to the tube ring gear such that any returning force applied by the inner brake pad against the planetary gear train of the piston assembly will be borne primarily by the tube ring gear, and thus, will not substantially adversely affect the operation of the planetary pinion and associated sun gear.

摘要： A vacuum brake booster provides a braking speed of application enhancement by increasing the air valve opening when a vehicle operator applies braking force quickly and forcefully. This is accomplished with a two part air valve which is normally expanded axially to a normal length by an internal spring but which may be shortened to open the air valve by a greater amount when the brake pedal input force is sufficient to move the air valve axially against another spring into contact with a shoulder of the power piston. The internal spring has a much higher preload than the other spring so that the booster operates with a fully axially expanded air valve in normal, low force brake activation. Once the air valve axially engages the power piston, however, the increase in air valve opening is immediate and substantial with any further increase in braking force. The air valve has an air valve input element having a pin projecting radially outward into an opening in a side wall of an air valve output element surrounding the air valve input element so as to axially engage a side of the opening to limit expansion of the air valve by the spring and thus define the normal axial length of the air valve.
摘要翻译： 当车辆操作员快速有力地施加制动力时，真空制动助力器通过增加空气阀开度来提供应用增强的制动速度。 这是通过两部分空气阀实现的，该空气阀通常通过内部弹簧轴向膨胀至正常长度，但是当制动踏板输入力足以使空气阀轴向移动时，该空气阀可以被缩短以将空气阀打开更大的量 抵抗另一个弹簧与动力活塞的肩膀接触。 内部弹簧具有比另一个弹簧高得多的预载荷，使得增压器在正常的低力制动器启动中用全轴向膨胀空气阀进行操作。 然而，一旦空气阀轴向接合动力活塞，空气阀开度的增加是立即的，并且随着制动力的任何进一步增加而是显着的。 空气阀具有空气阀输入元件，该空气阀输入元件具有径向向外突出到围绕空气阀输入元件的空气阀输出元件的侧壁中的开口中，以便轴向地接合开口的一侧以限制空气的膨胀 阀由弹簧限定，从而限定了空气阀的正常轴向长度。
