A golf car having a hydraulic fluid brake system. The hydraulic fluid brake system is implemented as a disk brake system which is responsive to hydraulic fluid pressure generated from a master cylinder. A brake pedal and associated linkage provides input to a master cylinder to generate a hydraulic fluid pressure to control a brake caliper assembly. The brake pedal has a range of travel, where a first portion of the range defines a service mode of operation and a second portion of the range defines a parking mode of operation. In the parking mode of operation, the brake pedal and linkage engages a detent to maintain application of the brake to provide a parking mode of operation. An accumulator in the brake system provides an input force to maintain hydraulic fluid pressure sufficient to retain a parking mode of operation.

A hydraulic brake system () for a vehicle such as a golf car or the like uses the same brakes () and same brake pedal () for both service braking and park and hold braking. The brakes () are selectively engaged, locked in their engaged position, and released using an integrated control assembly including a brake pedal (), an accelerator pedal (), and a brake pedal locking mechanism (). The brake pedal locking mechanism () is configured to automatically latch the brake pedal () in a locked position thereof and to automatically unlatch the brake pedal () from its locked position upon either subsequent movement of the brake pedal () into an overtravel position or subsequent actuation of the accelerator pedal (). In addition, a hydraulic accumulator () stores part of the energy generated upon brake pedal depression and consequent manual actuation of a master cylinder () of the system to maintain the brakes () in their fully engaged state when the brake pedal () is latched. The stored energy can also be used to help return an applied brake pedal () to its released position, in which case return fluid flow to the master cylinder () is damped to avoid undesirable severe kickback of the brake pedal. The accumulator () preferably comprises a modular spring and retainer assembly that can be preassembled separately from the remainder of the system and subsequently mounted on the system as a unit.

A utility box, of the type found on utility trucks, having a vertically-openable door which stores by resting on the top of the utility box. The door has as upper segment and a lower segment connected by a first hinge; and the upper segment is connected to the utility box top by a second hinge. The lower segment is about twice the height of the upper segment. Because of this construction, the door may be opened and closed nearby another vehicle or structure, since the maximum horizontal extension needed (from the box) to operate the door is about the same as the height of the smaller upper door segment.

A caliper brake assembly adapted to be mounted on a frame or housing in a position to engage each side of a brake disc, the assembly including a pair of bushings mounted on the frame, a one piece caliper housing mounted on the bushings, a brake pad assembly mounted on the bushings on each side of the brake disc, a ball ramp rotor assembly mounted on one side of the caliper housing for moving the brake pads into engagement with the brake disc, a flat spring mounted on the brake pad assemblies to prevent vibration of the brake pad assemblies.

A harness is disclosed that fits over an animal's head, such as a dog, and buckles around his chest behind the front legs. Straps, independent of the harness, are fitted around the dogs front legs and are attached to the leash through four D-rings (two D-rings attached to each side of the harness). The lower D-rings are located in such a position that the leg straps, when pulled back by the person walking the dog, pull straight back or perpendicular to the dogs legs. As the animal tries to walk faster or pull faster than the person walking the dog walks, the straps around the dog's legs pull back perpendicular to the dog's legs preventing the animal from walking faster than the person walking the dog. The harness is designed to restrict the movement of the dogs front legs by the force of the dogs own pulling power. The more the dog tries to pull, the less movement the dog has in his front legs. The dog is literally controlled by his own power and the pace the trainer or owner set for himself, without pain or injury to the dog.

A replaceable cartridge assembly for master cylinder having a housing with a longitudinal bore and an oil inlet connected to the longitudinal bore. The assembly includes a cylinder removably mounted in the longitudinal bore, a pair of seal rings mounted on the cylinder and located on each side of the oil inlet, an axial bore in the cylinder having a fluid outlet at one end connected to the brake system, and a pair of ports connecting the space between the seal rings to the axial bore in the cylinder. A piston in the cylinder has a cup seal around the outside and an O-ring seal spaced from the cup seal. A collar in the end of the axial bore in the cylinder retains the piston in the bore while a spring in the axial bore in the cylinder biases the piston away from the end of the cylinder.

A sealed thrust bearing including a housing having a circular base, an outer cylindrical wall formed around the outer edge of the base, and a cylindrical hub at the center of the base spaced from and coaxial with the cylindrical wall, a thrust bearing positioned in the space between the wall and hub, the thrust bearing including an inner race centered on said hub, a set of ball bearings seated on the inner race, and an outer race centered on the hub and seated on the ball bearings, the outer wall including a collar formed around the outer edge of the wall and a V-shaped ridge on the inside of the outer edge of the collar located in a position to sealingly engage the outer edge of the outer race and an outwardly angled lip around the inside of the hub positioned to sealingly engage the inner edge of the outer race to thereby seal the bearing lubricant within the housing.

Sealed thrust bearing

An electromagnetically actuated drum type brake embodying an improved support for the actuating magnet. The magnet is supported by a lever and when energized effects pivotal movement of the lever to actuate the brake. The support between the lever and magnet permits some floating movement of the magnet so as to accommodate for surface irregularities and relative movement between the magnet and the lever as is necessary to effect brake actuation. The support, however, restricts the degree of relative movement between the magnet and lever to acceptable values while transmitting the actuating force from the magnet to the lever. The support comprises an integral tab formed at the outer end of the lever which extends into an aperture in the magnet with sufficient clearance to permit limited movement in several directions. Rotary movement is, however, not restricted by this connection. The magnet housing also has an integral, outstanding tab that extends through an aperture in the lever to restrict the degree of pivotal movement and transmit the actuating force.

Magnet support for an electric brake

A mechanically actuated, spot type disk brake, having a servo action regardless of the direction of rotation of the associated brake rotor. The brake includes a slidably supported caliper and a pair of brake shoes, at least one of which is mounted for limiting axial, radial and rotary movement. The mechanical actuator comprises a device that moves the brake pad in a radial direction to achieve actuation. A cam construction translates radial movement of the brake pad into axial movement for operating the brake. The same cam construction also translates rotary movement into axial movement for achieving self energization.
