Filed:

Apr 21, 1983

Appl. No.:

6/487542

Inventors:

Richard T. Hendrickson - South Bend IN

Assignee:

The Bendix Corporation - Southfield MI

International Classification:

F15B 910
B60T 1300

US Classification:

91519

Abstract:

A brake apparatus 10 having a master cylinder 16 with a flange 24 connected to a first shell 56 of a booster 18 and a stationary firewall 71 of a vehicle. A first wall 70 located between the flange 24 and first shell is connected to a piston 38 in the master cylinder 14. A second wall 144 located between the first shell 56, flange 24 and a second shell 121 is linked to the first wall 70 by a plurality of bolts 180 that pass through the flange 24. A valve 102 in response to an input controls the development of a pressure differential across the first and second walls 70 and 144. This pressure differential creates a force such that the first wall 70 pushes piston 38 while the second wall 144 pulls the first wall 70 to pressurize fluid in the master cylinder 16. Since the flange 24 fixes the master cylinder 16 to a stationary firewall 71, measurable axial deflection is eliminated and the entire input is used to operate valve 102 and effect a brake application.

International Classification:

F15B 13044

US Classification:

13759617

Abstract:

The combination solenoid valve and shuttle valve (60) with self-cleaning orifice (92) comprises a shuttle valve (50) which is slidingly and sealingly received at an end (40D) of the solenoid valve (40). The shuttle valve (50) includes a stepped interior opening (54) which includes an insert (55) providing a shuttle valve seat (91) opposite a self-aligning solenoid valve seat assembly (94) of the solenoid valve (40). The valve seat (91) of the shuttle valve (50) includes an orifice (92) which extends from an end opening (70) of the insert and communicates with an insert passage (63) at an outer radial portion of the insert (55). An opposite radial side of the insert (55) includes a port (67) which communicates with a longitudinal passage (66) of the insert (55). Disposed within the longitudinal passage (66) is a brake-master cylinder check valve (59), and a stabilization check valve (58) adjacent a filter element (80) which permits communication with the insert passage (63). The shuttle valve (50) includes an end passage (64) having a pump check valve (57) and which communicates with an interior cavity (65) of the insert member (55).

International Classification:

F16D 2306
B60K 1734
B60B 2702

US Classification:

192 53E

Abstract:

A remotely controlled manual hub clutch assembly includes an axle and a wheel hub rotatably mounted on a vehicle housing. A pair of relatively movable coupling portions provide an engageable and disengageable driving connection between the axle and the wheel hub. The vehicle operator may engage and disengage the coupling members by moving a linkage connected to a movable one of the coupling members. A synchronizer prevents engagement of the coupling members until the rotation speeds of the wheel hub and the axle are substantially equalized so that the hub clutch can be engaged or disengaged while the vehicle is in motion. A non-rotating sleeve surrounds the axle and acts as a linkage to operate the coupling members.

International Classification:

US Classification:

Abstract:

A leveling device is attached to a vehicle to assist in maintaining a body assembly at its preferred height even when added weight is installed in the body assembly of the vehicle. The leveling device includes a housing which is connected to either the body assembly or a wheel mounting assembly and a piston which is movably supported in the housing extends therefrom to connect with the other of the body assembly and the wheel mounting assembly. The piston cooperates with the housing to substantially define a pair of chambers and a passageway within the piston connects the chambers with each other. A pressure source, such as a vacuum or low pressure air pump, is in communication with the passageway and a first valve normally closes communication between the pair of chambers and the pressure source. A control member carries a second valve and cooperates with the first valve, when the body assembly is moved toward the wheel mounting assembly beyond a normal travel distance, in order to open one of the chambers to the pressure source. As a result a pressure differential is established across the piston so as to oppose movement of the body assembly toward the wheel mounting assembly.

International Classification:

B60G 1700

US Classification:

280711

Abstract:

An automatic load-leveling pump is adapted for use with an air adjustable shock absorber to maintain a substantially constant vehicle height despite changes in vehicle loading. The pump includes a housing connected to the vehicle axle and a pump piston connected to the vehicle frame. A feedback device slides within the housing in response to air pressure and includes a cylinder, which, together with the pump piston, encloses a compression chamber. The feedback device moves in response to air pressure to control the compression ratio of the compression chamber.

International Classification:

B60T 1546
B60T 1110
H01H 3538

US Classification:

303 84A

Abstract:

A differential pressure switch includes a housing which carries a switch assembly which is actuated by movement of a differential pressure responsive piston slidable within the housing. The piston shifts in response to pressure differentials between the pressure levels in the chambers defined between the ends of the piston and the corresponding ends of the housing. The piston includes a pressure responsive stop that responds to pressure levels above a predetermined pressure level to engage the housing to thereby prevent shifting of the piston and actuation of the switch assembly regardless of the pressure differential across the piston, thereby limiting operation of the pressure switch to pressure levels below the predetermined maximum pressure level.
