Vehicle double disc brake - has brake pads demountable with taking off brake housing fitted to hub heat insulation

The brake arrangement consists of a rotary open brake housing whose opposing faces are the braking surfaces. Brake pads produce braking pressure acting in opposing directions, and are demountable without having to take off the brake housing. The housing is fitted with a number of extrusions meshing with corresponding splines, on the outer circumference of the hub. On the surface opposite the friction surface of the brake disc, ribs are provide. During rotation these act as ventilating vanes for removing heat generated during braking. The seating of the housing on the hub by extrusions resting in splines serves to restrict the flow of heat to the hub and the bearings.

Antiskid braking for vehicle driven axle - with clutch to block differential action on uneven grip road

The driven axle is retarded by a retarder (2) in the transmission line and has wheel speed monitors on each driven wheel. The difference in wheel speeds is monitored during retarder action and when the difference in wheel speed exceeds a programmed value the differential action of the differential is progressively blocked. A clutch (15) blocks the differential action and is controlled by a processor (13). The driven wheels can thus take upto half the braking force, on the wheel with most grip. If the blocked axles starts to skid, then the processor reduces the retarder action. ADVANTAGE - Improved stability, improved safety.

Increasing stability of multi-axle mobile construction machinery, e.g. excavators and crane vehicles

The method is for increasing the stability of multi-axle mobile construction machinery, where the engine (15) drives a gearbox (6) and one or more wheels (5) through drive shafts (9) and differentials (16). At least some of the drive train elements are mechanically tensioned against play in the gearing. Between each wheel and the relevant axle is an epicyclic gearbox (22 to 25) and wheel braking is by multiple disk brakes on the axles. Each axle individually is mechanically tensioned. The tensioning is done by first releasing the brakes on one of the driven axles, followed by running the machine until the gearing play is taken up by the rotation of each unbraked wheel, and then reapplying the brakes.

Part-lined disc brake with brake disc and brake shoe on each side

The thickness of both brake shoes when new is uneven in relation to the peripheral direction of the brake disc. When the brake shoes are applied, the outer edge parts of the brake linings of the shoes rest against the brake disc and face each other on the same level.The brake shoes can each be pressed from both sides by a brake piston. The surfaces of the brake pistons facing the brake shoes are stepped or slope towards the brake disc. When the brake shoes are pressed, the outer edges of the friction linings of the brake shoes rest against the brake disc and face each other on the same level ...

Fully lined disc brake - two symmetrical housing halves with inner and outer ring fixing method

A disc brake operating mechanism fits between two rings which support the linings and slide axially. The two housing halves (4, 5) have wheel bolts (3) with nuts (2) of a spherical bolt type. These fit on the outer edge or on both sides of the hub or axial flange (61). The wheel side housing section can be readily removed after wheel removal for brake ring (10, 11) change. Each housing half has an inner circular disc (41, 51) for connection to the hub. There is also a pair of outer rings (43, 53). The pairs of rings are fixed together and the resultant cylindrical or conical shape provides the required bending stiffness. Radial hollow ribs (42, 52) stiffen the inner circular disc.

Balanced brake reaction system - is for independent suspension and has reaction forces and support strut force acting through single point

The balanced brake reaction system for an independent suspension has the damper strut (5) braced on the support arm (7) on a ball and socket joint (6) while the brake callipers (11) are mounted on a lever pivoted about the axle (2). One end of the support arm is linked to the lever by a strut (9) angled so that its line of action passes through the point (A) through which the wheel loading and the brake reaction pass. The reaction and load forces pass through the same joint and are balanced. This ensures that the lateral reaction force on the upper mounting of the wheel support is zero, enabling simple mountings to be used.

Parking brake for disc brake assembly - overcomes necessity for mechanical application when fluid operation is used

Normal air or hydraulic type disc brakes require mechanical means to apply and hold them in the parking sense. This both increases weight and requires more space. This brake has brake shoes mounted on oscillating arms. A spring operated mechanical device is connected to these arms ending to release the brake. The parking brake is applied by fluid means, the force overcoming the springs. The max. radius of the disc is employed to minimise the force required. The brake then remains locked and is released by a simple and light mechanical arrangement.

Hydrostatic transmission for small vehicle - with hydraulic brake to stop gear shaft for gear change

The mass produced small vehicle has a combustion engine which drives a fluid flywheel. This in turn drives a single speed gear bos, which has the facility for reverse and neutral settings. In order to provide a simple gear change control the main shaft (4) of the gear box is braked during gear change. The gear brake operates from the hydraulic brakes of the vehicle, but at a lower pressure than is required to apply the wheel brakes. A pressure control system isolates the gear change brake from the wheel brakes when a set pressure is exceeded.

PORTAL BRAKING SYSTEM

A braking system for a portal lift assembly includes a shaft operably connected to a vehicle power source and effective to directly or indirectly rotate a wheel of the vehicle upon rotation of the shaft about its axis, a piston positioned along the shaft and effective for applying an axial force along the axis of the shaft, a fluid channel fillable with a non-compressible fluid and effective to apply a hydraulic force to the piston when pressure is applied to fluid in the line, a pressure plate positioned along the shaft and effective for applying an axial force along the axis of the shaft in response to the application of an axial force by the piston. A clutch pack is positioned between the pressure plate and the piston, and includes two sets of clutch plates radially surrounding the shaft. The first set of clutch plates is connected to the shaft in a manner effective to cause those clutch plates to rotate about the axis of the shaft when the shaft rotates. The second set of clutch plates is prevented from rotating about the axis of the shaft. Members of the first set of clutch plates are interspersed between members of the second set of clutch plates, so that when the clutch pack is sufficiently compressed by axial forces applied by the piston and the pressure plate, the first set of clutch plates is forced against the second set of clutch plates so that friction forces between members of the first set of clutch plates and members of the second set of clutch plates slow and may subsequently stop the rotation of the shaft. 1.
