摘要： A vehicle brake monitor assembly for an air disk brake includes a brake actuator having a pushrod projecting from inside a chamber of said brake actuator. The pushrod releasably actuates a lever arm of a caliper thereby moving the disk brake into a braking position when the pushrod is in an extended position and releasing the disk brake from the braking position when the pushrod is in a retracted position. The pushrod includes a pushrod shaft and a contact member biased in a telescoping relationship relative to the pushrod shaft and the lever arm of the caliper abuts the contact member counteracting the bias of the contact member. A sensor is integrated with the assembly proximate the contact member and detects movement of the pushrod relative to the lever arm and to the pushrod shaft.

摘要： The present invention provides a brake actuator assembly including a housing having a generally radial annular flange portion and a cover having a generally radial annular flange portion generally co-axially aligned with the generally radial annular flange portion of the housing. A cup-shaped flexible diaphragm having an outer radial annular rim portion is disposed between the generally radial annular flange portions of the housing and the cover. A retaining element generally surrounds and compresses the generally radial annular flange portions of the housing and the cover against the rim portion of the flexible diaphragm. The rim portion of the diaphragm includes a wedge-shaped edge portion and co-axially aligned flats on opposite sides of the rim portion adjacent to the wedge-shaped edge portion aligning the flange portions of the housing and the cover. In another embodiment, a flexible brake diaphragm includes a cup-shaped flexible diaphragm having an outer radial annular rim portion. The rim portion of the diaphragm includes a wedge-shaped edge portion and co-axially aligned flats on opposite sides of the rim portion adjacent to the wedge-shaped edge portion.

摘要： An improved gasket is designed for use on a complex interface surface between an oil pan and an engine. The gasket is formed as a one-piece molded part and is preferably injection molded from a silicone rubber. The gasket incorporates crush limiters at each bolt hole, and dual spaced sealing beads along the sides, with a circular sealing bead surrounding each bolt hole. The crush limiters control the amount of tightening of the bolts, while the sealing beads accommodate warpage of the oil pan, or undertightening of the bolt. In other features, tabs are disposed on each side of the gasket to accommodate an oil dip stick. The user of the gasket merely removes a cutaway portion associated with one of the tabs to provide a space for passage of the oil dip stick on the appropriate side. In this way, a single gasket can be incorporated into engine configurations having dip sticks on either side. In addition, an end tab is formed on one end of the gasket, and provides a saddle to be positioned outwardly of the engine to properly position the gasket.
摘要翻译：改进的垫圈设计用于油盘和发动机之间的复杂界面上。垫圈形成为一体成型部件，优选由硅橡胶注塑成型。垫圈在每个螺栓孔处均包含破碎限制器，并且沿着侧面具有双重间隔的密封珠，环绕每个螺栓孔的圆形密封珠。挤压限制器控制螺栓的拧紧量，同时密封珠容纳油盘的翘曲或螺栓的拧紧。在其他特征中，凸片设置在垫圈的每一侧以容纳油浸棒。垫圈的使用者仅移除与一个接头相关联的切口部分，以提供用于在适当侧面上通过油浸棒的空间。以这种方式，单个垫圈可以结合到在任一侧上具有浸渍棒的发动机构造中。此外，在垫圈的一端形成端部突片，并且提供一个鞍座以定位在发动机外部以适当地定位垫片。

摘要： A shield for a brake actuator has a bore closely surrounding a piston rod which is welded to a yoke. The shield is formed with a plurality of slits that allow portions of the shield between the slits to bend radially outwardly and allow the yoke to move through the bore. Thus, the invention allows the use of a yoke which is welded to a piston rod, and also allows the use of a shield which closely surrounds the piston rod.

摘要： The present invention provides a tamper-resistant fluid-operated brake actuator having a power spring housed within a head or cap which is attached to a flange case having one or more diaphragms or pistons responsive to changes of fluid pressure within the brake actuator chambers. In one embodiment, the head is attached to the flange case by a substantially continuous curvilinear annular metal retaining member which must be inelastically deformed or destroyed in order to remove the head from the flange case, thus rendering tampering more difficult. In another embodiment, the annular metal retaining member of the present invention is integral with the actuator head and which is metal-spun or the like onto the flange case.

摘要： A method of monitoring lateral force of a coil spring having a body and opposing end coils is disclosed. A fixture includes a base defining a planar surface with a shaft that extends from said planar surface at a normal angle to said planar surface. An axis defined by the coil spring is aligned with the shaft. Angular displacement from the shaft of an end coil is measured, and the angular displacement is correlated with a lateral force value.

摘要： An improved spring brake actuator includes an improved valve housing which incorporates pressure test points into the air supply, and further incorporates an anti-compounding valve. By incorporating the anti-compounding valve and test points directly into the valve manifold, the inventive spring brake actuator reduces the number of separate parts. The anti-compounding valve is operable to insure that there will be no compounding of the braking force.
