    摘要： A spring brake actuator is for braking a wheel of a vehicle. The spring brake actuator has an axially elongated housing having a parking brake chamber and a service brake chamber; a main compression spring in the parking brake chamber; a flexible diaphragm in the parking brake chamber; and a pressure plate in the parking brake chamber, the pressure plate located axially between the main compression spring and the flexible diaphragm. The flexible diaphragm has a contoured portion that inhibits radial shifting of the pressure plate with respect to the flexible diaphragm.

    摘要： The invention relates to a clamping and/or braking device with a base element (7) and a force-applying element (17), by means of which the generated clamping and/or braking forces can be transferred to an object (39), as well as at least two adjacent wall sections (3), which each apply force with an end region on the base element (7) and the force-applying element (17), and wherein the two or more adjacent wall sections (3) define an essentially sealed pressure chamber that can be pressurized with pressure or negative pressure, wherein the two or more wall sections (3) each have a bending region (3a), which is resistant to tensile force and nevertheless can be bent elastically so that the bending regions (3a) form an elastic element between the base element (7) and the force-applying element (17).By means of the force-applying element (17), in the unpressurized built-in state of the clamping and/or braking device (1), a predetermined clamping and/or braking force can be exerted on the object (39), wherein the two or more wall sections (3) and their bending regions (3a) are formed, such that when the pressure chamber is pressurized with positive pressure or negative pressure as a result of a change in the curvature of the bending regions (3a), the clamping and/or braking forces transferred by the force-applying element (17) to the object (39) are changed or the force-applying element (17) is moved in the direction towards the base element (7) or away from this element.According to one alternative, the two more adjacent wall sections (3) can also be connected rigidly to the force-applying element (17) and/or to the base element (7).

    摘要： A force balanced brake system for effecting ratio changes in transmission comprising a band brake unit (10) having separate bands (12 and 13) selectively engageable with a reaction drum (5), each with a piston apply lug (16 and 18) and anchor lug (17 and 19). With equal area apply pistons (21 and 41 charged with common pressure, apply and reaction forces are equal and opposite. Side loads are eliminated so the brake drum (5) is only piloted as a rotating component. The system provides freewheeler type shifts without specific one-way devices. The brake band unit (10) provides engine braking during vehicle coast. For freewheeler type shifts, the system is staged in a one-way mode and the torque capacity of the band is regulated to vary in direct relationship with the torque band (10) also reduces to a near zero value allowing the brake drum (5) to turn freely in the direction opposite to previous reactive torque.

    摘要： A hydraulic operating unit for the friction engaging apparatus of a transmission provides a hydraulic operating unit which permits the introduction of a low-pressure working fluid to permit the forceable disengagement of the hydraulic operation unit to work against the fluid which would normally urge the unit into engagement. The effective pressure-receiving area on the releasing side of a hydraulic power servo mechanism is made sufficiently large with respect to the effective pressure-receiving area on the engaging side of the servo mechanism while the piston diameter is kept small in order to save space in the construction of the servo mechanism while at the same time permitting the device to effectively disengage the friction mechanism.

    摘要： The present invention relates to an improvement in a band brake wherein a plurality of rotors and stators provide for braking a rotatable member when a friction lining on the band brake is engageable with the rotatable member. The rotatable member carries an axially extendible assembly which is engageable with the friction lining to provide for extension of the axially extendible assembly. When the assembly is extended, the rotors which rotate with the rotatable member and the stators which are carried by a support housing are moved axially into frictional engagement with each other. The extendible assembly comprises a first element carried by a key on the rotatable member to impart rotation with the rotatable member and permit axial movement relative to the rotatable member, and a second element resiliently connected to the first element. The first element and second element include a cam therebetween such that when the second element engages the friction lining of the band brake, the second element rotates through a limited angle relative to the first element to increase the axial spacing between the elements by the action of the cam. The first element is also engageable with the friction lining to eliminate noise and instability in the action between the elements and the cam. In order to engage the friction lining with the rotatable member, the support housing forms a hydraulic actuator with at least one piston and a pair of links which are pivotably connected to each other cooperate with the friction lining when the hydraulic actuator is operated to contract the friction lining into engagement with the rotatable member.

    摘要： A control valve for a hydraulically actuated steering clutch and steering brake are provided. The valve comprises a valve housing having a plurality of bores therein, right and left hand operating rods and first, second and third spools slidably disposed within said respective bores. The spools are normally urged towards a neutral position where the hydraulic fluid from a hydraulic pressure supply source is discharged, through a drain circuit. The first and third spools are arranged such that when either of the right and left hand operating rods is moved on a predetermined stroke, the hydraulic fluid delivered by the supply source is supplied into either the pressure chamber of a right hand steering clutch or that of a left hand steering clutch, and when the operating rod is moved on a further predetermined stroke, the hydraulic fluid is supplied into either the pressure chamber of a right hand steering brake or that of a left hand steering brake, whereby the steering clutch and the steering brake can be controlled by a common control valve.
