摘要： Dual master cylinders are arranged to apply hydraulic pressure to a single set of vehicle brakes through a double check valve and single brake fluid conduit. A first of the master cylinders is actuated by compressed air in response to manipulation of an operator's service brake control, while the second master cylinder is actuated to a lesser extent by compressed air responsive to an operator's retarder control. A modulatable emergency brake control may independently and simultaneously actuate both master cylinders together with a third master cylinder coupled to separate brakes. Thus, braking capacity remains available if the service brake system or the retarder brake system or both should fail, or if the emergency system should itself fail while either the service system or the retarder system remains functional. Upon a significant lowering of emergency system air pressure, a warning is given to the operator who may then initiate controlled emergency braking until the air pressure reaches a predetermined minimum at which point all three master cylinders are automatically actuated and the brakes cannot be released until emergency system operating pressure is restored. Further means are present to warn of incipient failure of other parts of the system, and means are provided for optionally inactivating a portion of the vehicle brakes when not needed which means is overrideable by the emergency system described above. Further means speed response of the system to actuation and release of brake controls and provide for rapid automatic purging of air from the hydraulic portion of the system.
摘要翻译：双主缸设置为通过双止回阀和单个制动液管道将液压压力施加到单组车辆制动器上。响应于操作者的行车制动控制的操作，第一主缸由压缩空气致动，而响应于操作者的减速器控制，第二主缸在较小程度上由压缩空气致动。可调制的紧急制动控制可以独立地并且同时致动主缸与连接到单独的制动器的第三主缸。因此，如果行车制动系统或减速器制动系统或两者都应该失效，或者当服务系统或减速器系统保持功能时应急系统本身都会失效，则制动能力仍然可用。在应急系统空气压力显着降低的情况下，向操作者发出警告，然后操作人员可以启动受控的紧急制动，直到空气压力达到预定的最小值，此时所有三个主缸都被自动启动，并且制动器在紧急情况下不能释放系统工作压力恢复。存在用于警告系统其他部件的初始故障的另外的手段，并且提供了用于在不需要时可选地使一部分车辆制动器失活的装置，这种装置可由上述紧急系统覆盖。进一步意味着系统对制动控制器的致动和释放的速度响应，并提供从系统的液压部分快速自动吹扫空气。

摘要： A strain-limiting fastening apparatus for containing a source of potential energy in entrapped relation between a pair of axially separable members includes a plurality of fasteners securable to one of the members for substantially axially holding the other member thereto in opposition to the source of potential energy, and a plurality of stops on the other member for limiting the degree of maximum axial adjustment of an individual fastener to a predetermined incremental amount until all of the fasteners have been adjusted to this amount, to thereby limit the degree of cocking of the other member during the assembly or disassembly thereof in order to minimize unequal loading of the fasteners by the source of potential energy.

摘要： An outer bearing race is mounted in a bore defined in a support member and an inner bearing race is universally mounted in the outer race to form a ball and socket connection therebetween. An annular retainer is secured in the bore on each side of the outer race to retain an annular lip seal therebetween. A flexible lip of the seal extends radially inwardly into sealing contact with a convex spherical surface formed on the inner race.

摘要： A control system for a spring-applied service brake which can also be used as a parking brake. Pressure from the vehicle hydraulic system is normally used to release the brakes. In the event of a loss of the primary pressure from the hydraulic system, the control system switches automatically to use of secondary pressure from the vehicle compressed air system to release the brakes, while maintaining the ability of the operator to apply the brakes by normal operation of the service and parking brake controls.
