Description
SPECIFICATION
Axles
This invention relates to rigid beam axles for the driven wheels of land vehicles, of the type having a hollow rigid oil-filled axle housing incorporating a differential in the central part (not necessarily at the geometric mid-point) of the housing by which the drive of the vehicle engine is transmitted through drive shafts to the wheel hubs journalled on the outer ends of the axle housing, reduction gearing being incorporated in the axle housing to provide a speed reduction between the differential and each wheel hub. Such an axle is referred to herein as an axle of the type specified.
The invention is particularly intended for use with an industrial forklift truck, although if required it could be used with other types of land vehicle.
A major problem with industrial forklift trucks is brake maintenance, as a result of the high wear rate of conventional drum brakes in such vehicles.
An oil-immersed disc brake system acting on the input side of a reduction gear mechanism provides a very efficient vehicle brake with a very small rate of wear as compared with conventional drum or disc brakes acting directly on the wheel hub. Certain off-highway vehicles have been provided with such brakes incorporated in their driven axles. The brakes have been housed in the central part of the axle housing adjacent to the differential, with the reduction gear mechanism located either also in the central part of the axle housing or in the region of the wheel hubs.
However such axle arrangements are not suitable for use with industrial forklift trucks on account of the geometry of the fork, mast and chassis members, etc., which take up most of the available space in the "central" region between the driven wheel hubs.
An object of the invention is to provide an axle of the type specified incorporating oil-immersed disc brakes, which is suitable for use in a forklift truck.
The invention from one aspect comprises an axle of the type specified in which each wheel hub is driven through a reduction gearing having an oil-immersed disc brake acting on its input, each reduction gearing and its associated disc brake being located within the axle housing immediately adjacent to the associated wheel hub. With this arrangement, the reduction gearing and their associated.brakes occupy the regions where in a conventional forklift truck axle the drum brakes would be situated.
According to the present invention from another aspect, an axle of the type specified, particularly although not exclusively for use in a forklift truck, has a reduction gearing for each wheel hub mounted in the respective outer end portion of the axle housing adjacent to the wheel hub, with an associated oil-immersed disc brake also mounted in the respective outer end portion of the axle housing inboard of and adjacent to the reduction gearing and acting on the input thereto.
Preferably each of the disc brakes has a hydraulic actuator whose cylinder is afforded by a part of the outer end portion of the axle housing.
The invention thus enables an axle arrangement to be provided whose "central" portion is relatively compact, housing the differential structure only, leaving adequate space in the central region between the driven wheels for accommodating the chassis members, mast etc.
of a forklift truck. Moreover the arrangement provides easy access to each brake unit, should the need arise, without the necessity for removal of the axle from the vehicle.
In one construction of the invention, each wheel hub is journalled on a spigot projecting from one outer end of the axle housing and is driven by a stub axle extending within the spigot and coupled to the output of the associated reduction gearing, the input of the reduction gearing being coupled to the outer end of a driving shaft whose inner end is coupled to one of the output pinions of the differential, and the disc brake acts directly on the outer end of the driving shaft.
The invention from yet another aspect comprises a forklift truck having a driven axle at its front (fork) end, the axle being of the type specified with each wheel hub carrying a driven ground wheel of the truck and being driven through a reduction gearing having an oilimmersed disc brake acting on its input, each reduction gearing and its associated disc brake being located within the axle housing immediately adjacent to the associated wheel hub.
The invention may be carried into practice in various way, but one specific embodiment thereof will now be described by way of example only and with reference to the accompanying drawing, which is a view in longitudinal section of an oilfilled beam axle for a forklift truck.
In this embodiment the axle 10 is of the fullyfloating type having a rigid hollow housing structure 11 constituting the "beam" of the axle, with a differential 1 2 housed in a casing member 13 forming an enlargement of the central part of the housing. The input spindle 14 journal led in the casing 13 carries the usual coupling 1 5 for connecting it to the rear end of the vehicle propeller shaft, and carries at its other end a bevel pinion 1 6 in mesh with the crown wheel 1 7 of the differential.The differential 1 7 is of conventional construction, comprising a cage 1 8 to which the crown wheel 1 7 is bolted, two pairs of bevel planet pinions 1 9 (one pair only being shown in the drawing) journalled on spindles 20,21 supported perpendicular to one another in the cage 18, and two bevel output pinions 23, 24 in permanent mesh with the four planet pinions 20, 21 on opposite sides thereof, the output pinions 23, 24 being coupled by spine connections 26 respectively to the inner ends of a pair of drive shafts 27 extending in opposite directions from the differential within the axle housing 1 The cage 18 is journalled by bearings 29 in the differential casing 1 3 which is oil-filled, the bearings 29 being of tapered roller form and being provided with screw threaded adjustment rings
30. The shafts 27 are individually rotatable
relatively to the cage 1 8 under the control of the
differential mechanism.
The axle housing 11 comprises, in addition to the central differential casing member 13, a pair of oil-filled tubular housing members 35 secured by bolts 36 to opposite sides of the differential casing 1 3 and supporting the wheel hubs at their outer ends, each housing member having a groove 35A for mounting it on the vehicle suspension or chassis. Thus each housing member 35 has a bellhousing 37 bolted to its outer end by bolts 38 and an integral spigot projects outwardly from the bellhousing, on which spigot a wheel hub 42 is journalled by a pair of wheel bearings 43 of tapered roller form. Each of the hubs 42 is provided with a coaxial stub axle 44 extending inwardly within the spigot 39 and driven from the respective drive shaft 27 through an epicyclic
reduction gearing generally indicated at 41.Each
of the reduction gearings 41 comprises a ring gear
45 secured within the interior of the bell-housing
37 with its teeth directed inwardly and meshing with a set of planet pinions 46 journalled on bearing pins 47 of a planet carrier assembly 48 which is coupled to the stub axle 44 by means of a spline connection 49. The planet pinions 46 are also in permanent mesh with a sun gear 50 formed on or carried by the outer end of the drive shaft 27 which extends within the oil-filled housing member 35. Thus each wheel hub 42 is driven by the drive shaft 27 with a speed reduction provided by the epicyclic gear 41, whose reaction member is afforded by the bellhousing 37 forming a part of the rigid axle housing
11. Oil seals 52 are provided between the hub 42 and the bell-housing 37.
The step-down ratio provided by each of the reduction gear mechanisms 41 will be determined in accordance with the design requirements of each case, but in an exemplary axle for an industrial forklift truck, having a primary step-down ratio of 3.6:1 provided at the pinion 16 and crown wheel
17 of the differential, a secondary reduction ratio of 5.6:1 in each of the gear mechanisms 41 has been found suitable, giving an overall final drive speed reduction of 20.3:1 between the vehicle
propeller shaft and the driven road wheels.
Also mounted in each of the bell-housings 37 is an oil-immersed disc brake generally indicated at
60 and acting between the bell-housing and the outer end of the respective drive shaft 27. The brake 60 comprises a set of brake discs 61, each formed with a radially-slotted central aperture engaged in a spline formation 64 on the drive shaft 27 so that the disc 61 can slide axially along the shaft 27 but are coupled to it for rotation therewith. Interposed between the discs 61 are a set of annular brake rings 64 having radial slots in their outer peripheries which are engaged in internal splines 65 in the bell-housing 37 so that the brake rings 64 are angularly fixed with respect to the bell-housing but are free to slide axially therein.The sets of co-operating discs 61 and rings 64 can be frictionally clamped in the axial
direction against an abutment ring 67 to operate
the brake, by means of a hydraulic actuator 70
housed in the outer end of the respective housing
member 35. The actuator 70 comprises an
annular piston 71 which slides in, and is sealed
against coaxial internal cylindrical surfaces 72,
72A machined dn the wall of the housing member
35. An annular pressure chamber 73 is formed
between a radial face 74:of the housing member
35 and a:radial flange 75 on-the annular piston
71, and an inlet recess 76 in the wall of the housing member 35 communicates with the pressure chamber-73.The recess 76 is closed by a bored screw plug 77 carrying a nipple 78 for the attachment of a hydraulic pressure fluid line (not shown) for the admission of fluid pressure to the chamber 73 to act on the rear circumferential face of the piston flange 75 so as to force the piston 71 against the stack of brake discs and rings 61,74 when it is required to apply the brake for braking the drive shaft 27 on the input side of the
reduction gearing 41 and hence to brake the
hub 42.
The disc brake 70 and likewise the reduction gearing 41 at each end of the axle are immersed in the oil filling the housing members 35 and casing
13, and it will be seen that these two sets of mechanisms are located in the outer end portions of the axle housing 11 at each end thereof, adjacent to the wheel hubs, with the brakes inboard of the reduction gearing, and the brakes with their hydraulic actuators, and the reduction gearings, occupy much of the region of the axle which in known forklift truck axles would be occupied by conventional drum brakes. With this arrangement the central differential casing 13 can be of compact design and dimensions, leaving adequate space for the chassis members, mast and fork mechanism of the truck centrally between the driven wheels. The brake mechanisms are selfcompensating for wear, and are easily accessible for maintenance if required simply by the removal of the respective bell-housing 37 complete with wheel hub, and without any need for the removal of the complete axle assembly from the vehicle.
