Abstract
A device for providing supplementary braking control to a towed vehicle e.g. a caravan when coupled to a towing vehicle comprises means for sensing braking of a towing vehicle e.g. by sensing brake light application; means for activating the towed vehicle brakes e.g. a compressed air diaphragm (44, Fig.4) or an electromagnetic actuator; and means for regulating the degree of braking of the towed vehicle. Regulating the degree of braking is achieved by measuring the degree of braking of the towing vehicle (Db1) e.g. by measuring compression of hitch damper (22, Fig.2), measuring the degree of braking of the towed vehicle (Db2) e.g. by measuring force or pressure exerted by diaphragm, comparing Db1 and Db2, and increasing Db2, if Db1>Db2 and decreasing Db2, if Db1<Db2.
Description
2362693 1 CARAVAN BRAKING DEVICE This invention relates to a device
supplementary to the standard inertia hitch braking system for controlling braking of a towed vehicle when coupled to a towing vehicle which acts directly on the existing braking system whenever the towing vehicle brakes are applied.
Background of the Invention
Many towed vehicles have brakes operating on the 70 year old principle of inertia hitch.
A spring loaded hydraulically damped sliding member (inertia hitch damper) in line with the coupling on the towed vehicle is compressed when the towing vehicle brakes absorb the initial residual momentum of the towed vehicle. This compression acts upon a lever generating a pulling action on a brake rod which in turn applies the towed vehicle brakes. The degree of braking is dependent on the deceleration of the towing vehicle, the weight of the towed vehicle and the amount of compression of the hitch.
As the towed vehicle slows down to just below the speed of the towing vehicle, the increasing distance between the two vehicles extends the inertia hitch damper thus reducing the braking effort applied by the towed vehicle brakes. This mechanism operates until an equilibrium state is achieved with the braking effort of the two vehicles equal. When the towing vehicle releases its brakes and accelerates forward, the inertia hitch damper fully extends and all braking effort in the towed vehicle is removed.
The inertia hitch damper relies on the towed vehicle compressing the damper first in order to activate the brakes. The compression of the damper is often perceived as a push. Conversely, a pulling effect is felt on acceleration. If the two vehicles are not 2 aligned end to end, the lateral force on the towing vel-cle arising from the residual momentum of the towed vehicle can lead to severe instability (snaking) or total loss of control Oack-knifing) when braking heavily, for example, in an emergency or when descending. Snaking can also be induced by the sudden imposition of a side load on the towed vehicle from cross-winds when emerging from a cutting or crossing a bridge, or when being passed by a large vehicle at speed. These problems are exacerbated as the weight of the towed vehicle increases relative to that of the towing vehicle.
SummaLry of the Invention This invention provides a solution to the problem of severe instability or loss of control experienced on heavy braking by drivers of towing vehicles by providing a device which applies a braking force to the towed vehicle brakes when the towing 15 vehicle applies brakes and thus prior to compression of the inertia hitch damper.
Thus, a first aspect of this invention provides a device supplementary to the standard inertia hitch braking system for controlling braking of a towed vehicle when coupled to a towing vehicle comprising:
(i) a means for sensing braking of a towing vehicle; (ii) a means for activating the towed vehicle brakes; and (iii) a means for regulating the degree of braking.
wherein the means for regulating the degree of braking comprises:
(i) a means for measuring the degree of braking of the towing vehicle; (ii) a means for measuring the degree of braking of the towed vehicle; (iii) a means for comparing the degree of braking of the towing vehicle with the degree of braking of the towed vehicle; (iv) a means for increasing the degree of braking of the towed vehicle if the degree of braking of the towing vehicle is greater than the degree of braking of the towed vehicle; and 3 (v) a means for decreasing the degree of braking of the towed vehicle if the degree of braking of the towing vehicle is less than the degree of braking of the towed vehicle.
The meaning of 'a device supplementary to the standard inertia hitch braking system for controlling braking of a towed vehicle when coupled to a towing vehicle' is a device which works alongside the standard braking system controlling braking effort.

Typically, the means for sensing the braking of the towing vehicle comprises a means for sensing the towing vehicle brake light circuit by, for example, electrical connection. Where appropriate, the towing vehicle brake light circuit is preferably Galvanically isolated from that of the supplementary braking control device.
Examples of means for activating the towed vehicle brakes include accumulators and diaphragms, in particular air diaphragms.
The means for activating the towed vehicle brakes may also be linked to the handbrake on the hitch.

Figure 3 is a side elevation (part sectional) of an inertia hitch device without a hand brake; Figure 4 is an under side view of a trailer axle showing an actuator connected to a brake rod by a sliding coupling; and Figure 5 is a schematic view of a wiring loom.
Detailed Description of the Invention
A trailer embodying an A-frame design, shown in Figure 1, comprises a single axle (11) and a standard inertia hitch braking device (12) positioned at the leading edge of the trailer. The inertia hitch device (12), which incorporates a handbrake (13), is connected via a brake rod (14) to two brake cables (15) which each operate a brake (16) housed in each wheel.
The mechanism of the inertia hitch device (12), illustrated in greater detail in Figure 2, comprises a brake rod (14) attached to the lower end of a vertically mounted lever (21), the upper end of which impinges upon an inertia hitch damper of a type typically used in an inertia hitch device (22). A handbrake (23) is attached to the opposing end of the inertia hitch damper (22) and a rubber gaiter (24) fitted around the exposed sliding part of the inertia hitch damper (22) which contains lubricant and additionally protects against dust and dirt.
6 Figure 3 shows an alternative arrangement of inertia hitch device comprising an inertia hitch damper (22) with a ring mounting (3 1) attached to the leading end of the damper.
As shown in Figure 4, a brake rod (14) is connected via a brake rod extension (4 1) and a sliding coupling (42) to an output shaft (43) of an air diaphragm (44) (not previously shown in Figure 1). The said air diaphragm (44) is attached to the axle (11) with an axle bracket (45) through which pass two brake cables (15) terminating at an equalising bar (46). The brake rod (14) passes through the centre of the aforementioned equalising bar (46) and is attached thereto such that movement of the brake rod (14) in the direction of the arrows as shown results in an equal movement of the equalising bar (46). The air diaphragm (44) is activated by an air compressor (not shown) optionally sited on the trailer. As an alternative to the sliding coupling (42) shown in Figure 4, a positive join coupling such as a screw coupling may be used.
When using the inertia hitch device (12) alone, deceleration of the towing vehicle compresses the inertia hitch damper (22) which acts upon the lever (21) pulling the brake rod (14) forward. The equalising bar (46) is pulled forward in harmony with the brake rod (14) so pulling upon the brake cables (15) activating the wheel brakes (16).
When the braking system is fitted with an air diaphragm (44), according to the invention, the initial mechanism of braking no longer involves compression of the inertia hitch damper (22). On operation of the air diaphragm (44), the output shaft (43) of the air diaphragm (44) pushes against the brake rod extension (41) so pushing the brake rod (14) and the equalising bar (46) to which it is connected. The lateral movement of the equalising bar (46) pulls the brake cables (15) activating the wheel brakes(16). This lateral movement of the brake rod (14) pulls the upper part of the lever (21) away from the inertia hitch damper (22). Thus the wheel brakes (16) are activated without compression of the inertia hitch damper (22).
For operation of the air diaphragm (44), a compressor switch circuit is connected to the towing vehicle brake light circuit in such a manner that the compressor is switched on when the towing vehicle brakes are applied. The power requirement for the 7 compressor is typically 5 amperes at 12 volts drawn either from a trailer- borne battery or directly form the towing vehicle electrical circuit. Activation of a pressure release solenoid valve on the compressor by, for example, a single short electrical pulse generated when the towing vehicle brake lights are turned off, releases the wheel brakes (16).
An alternative to an air diaphragm and compressor is the use of an electromechanical actuator connected to the towing vehicle brake light circuit in a similar manner as the air diaphragm and compressor combination and which when activated, 10 operates the wheel brakes (16) in a manner.
In order to regulate the amount of braking effort, the compressor is controlled by two sensors. The first sensor is located in, on, or near the inertia hitch device (12) and measures the degree of compression of the inertia hitch damper (22). A two part sensor comprising a magnet (25) and a magnetic field sensor (26) is shown in Figure 2. The magnetic field sensor (26) produces a voltage output which is proportional to the distance between itself and the magnet (25). By placing one component of the sensor, either the magnet (25) or the Hall effect device (26), on the sliding part of the inertia hitch damper (22), and the other on a nonsliding part of the inertia hitch device (12), compression of the inertia hitch damper (22) can be monitored by a proportional change in the voltage output of the magnetic field sensor (26) as it approaches the magnet (25).
An alternative device for measuring the linear displacement of the inertia hitch damper (12) is a rectilinear potentiometer (29) which produces a voltage output proportional to its degree of compression.. By attaching one end of the potentiometer (29) to the trailer chassis (27) and the other to a bracket (28) hanging perpendicular to the handbrake (23), the degree of compression of the inertia hitch damper (22) is directly measured. Other devices which can measure the linear displacement of the inertia hitch damper and can be fitted to the trailer in a similar way include opto- digital and mechanically-driven rotating potentiometers.
8 The second sensor (not shown) generates a signal which is proportional to the braking effort applied by the air diaphragm (44), more particularly the force or pressure exerted by the air diaphragm output shaft (42) on the brake rod extension (41).
The supplementary braking device operates in the following manner:
(a) Application of the towing vehicle brakes relays a signal to the compressor; (b) The compressor pressurises the air diaphragm (44) such that a predetermined amount of force is applied to the wheel brakes (16) sufficient to prevent compression of the inertia hitch damper (22) under gentle braking; (c) The voltage outputs of the first and second sensors are compared; (d) If comparison of the voltage outputs of the two sensors indicates that the degree of braking of the towing vehicle is greater than the degree of braking of the towed vehicle, then the amount of force applied to the wheel brakes (16) is increased; (e) If comparison of the voltage outputs of the two sensors indicates that the degree of braking of the towing vehicle is less than the degree of braking of the towed vehicle, then the amount of force applied to the wheel brakes (16) is decreased by opening the pressure release solenoid valve on the compressor; (f) A signal is relayed to a compressor controller which opens the pressure release solenoid valve releasing the trailer wheel brakes (16) when the towing vehicle brakes are released.
A typical wiring loom linking all the components of the supplementary braking device of the invention, shown schematically in Figure 5, has at its centre a control unit 9 (5 1) connected to the towing vehicle low voltage circuit (52) and/or an optional trailer low voltage circuit (53). The control unit receives signals from the first (54) and second sensors (55) and the towing vehicle brake light circuit (56). The control unit (5 1) relays signals to activate (57) or deactivate (58) the compressor (which in turn pressurises or 5 depressurises the air diaphragm (44)).
The output from the first sensor (54) can be used to pulse width modulate the compressor motor so varying the motor speed and thus air diaphragm (44) pressure.
It will be understood that the foregoing is merely exemplary of an embodiment of the invention and that modifications can be made without departing from the true scope of the invention as defined in the accompanying claims.
