Abstract

A suspension system for a leanable vehicle, such as a motorcycle, has a pair of laterally spaced wheels 1 and 2 with hydraulic dampers 18 and 19 associated with the wheels 1 and 2 and control means in the form of a changeover valve 26 selectively operable to cause the dampers 18 and 19 to operate either independently, with line 24 connected to line 25 and line 27 connected to line 28 or simultaneously with line 24 connected to line 27 and line 25 connected to line 28, to alter the operating characteristics of the suspension.

Description

I
Hydraulic damper system This invention relates to suspension systems for a pair of laterally spaced wheels of a leanable vehicle such as a motorcycle type vehicle European patent specifications Nos 01998472 3 and 03253106.3 disclose narrow tracked, leanable, four wheeled vehicles including various suspension locking devices to stabilize the vehicle One of these devices restricts the flow of hydraulic fluid through the suspension dampers. The current invention provides a specific embodiment of this device The present invention provides a suspension system for a leanable vehicle that allows hydraulic dampers associated with a pair of laterally spaced wheels to work selectively either independently or simultaneously to alter the operating characteristics of the suspension.
The invention will now be further described by way of example with reference to the accompanying drawings, in which Fig I depicts the vehicle's rear suspension arrangement comprising a pair of ground engaging wheels I and 2, which are mounted onto swing arms 3 and 4 respectively via stub axles (not shown). Only the free ends of the swing arms 3 and 4 are shown, the other ends are pivoted about an axis that lies substantially parallel to the rotational axis of the wheels I and 2. Connected between one arm of the balance beam 6 and the swing arm 3, via spherical joints 9 and 10 is the connecting rod 7. Similarly, connected between the other arm of the balance beam 6 and the swing arm 4, via spherical joints hand 12, is a connecting rod 8. The balance beam 6 can turn about pivot point 13 fixed to the cross head 14 The cross head 14 can reciprocate on static guide rods 15 and 16. The static rods 15 and 16 are anchored at each end. One end of a suspension spring 17 bears against the cross head 14. The other end of the spring 17 bears against an anchor point.
Housings I 8d and I 9d of the hydraulic suspension dampers 18 and 19 are each located via a swivel joint (not shown) to an anchor point. The piston rod I 8a of the damper 18 is pivoted at one end to the balance beam 6 via swivel joint 22. The piston rod 19a of the damper 19 is pivoted at one end to the balance beam 6 via swivel joint 23.
Thereby, when the wheels 1 and 2 simultaneously hit the same sized bump, as in Fig.2, their upward motion compresses the spring 17 via the cross head 14, balance beam 6, connecting rods 7 and 8, swing arms 3 and 4 In Fig. 2 the dampers 18 and 19 are also activated by the movement of balance beam 6 The balance beam 6 equalises the forces exerted by the spring 17 between the wheels I and 2 ShOuld just one wheel encounter a bump, as in Fig 3, its upward motion compresses the spring 17 via the cross head 14, balance beam 6, connecting rod 7 and swing arm 3. In Fig. 3 the angled balance beam 6 still equalises the forces exerted by the spring 17 on the wheels I and In Figs. 4 and 5 the balance beam 6 turns when the vehicle leans to negotiate a bend By stopping the balance beam 6 from turning the vehicle can be prevented from falling over in the sort of unbalancing event that commonly leads to motorcycle and scooter accidents The balance beam 6 can be stopped from turning by interrupting the flow of hydraulic fluid through the damper housings 18d and 19d Thus automatic or manual control means enables substantially all the independent movement of wheels 1 and 2 to be eliminated by substantially preventing the rotational movement of the balance beam 6 about axis 13 whilst still allowing wheels I and 2 to simultaneously have full suspension movement as in Figs 2, 6, 7 Fig 8 shows the system in the normal independent suspension mode. The damper 18 contains a two-way piston 18b which is fixed to the piston rod 18a. Fixed to the inside of the housing 18d is a damper block 18c. The damper 19 and its components are the same as damper 18 but are identified with the number 19. The two ends of housing 1 8d are interconnected by hydraulic lines 24 and 25 via a hydraulic changeover valve 26 The two ends of housing 1 9d are similarly interconnected via hydraulic lines 27 and 28 This arrangement forms two independent hydraulic circuits as indicated by the two shaded areas A movement in the direction of A by piston rod I 8a or B by piston rod I 9a, via connecting apparatus such as balance beam 6, moves piston I 8b or I 9b respectively to push the hydraulic fluid in the direction of the hydraulic flow arrows.
The opposite movement of A or B will cause the hydraulic fluid to move in the opposite direction to the hydraulic flow arrows. In each case the movement of the hydraulic fluid in each housing I 8d or 19d is independent of the other. Positioned on each hydraulic circuit is a hydraulic flow sensor 29 and 30 When these sensors 29 and detect substantially equal flow rates in opposite directions the monitoring control unit 31 signals the solenoid 32 to turn the hydraulic valve 26, via axis 33 by a linkage (not shown) connected between axis 33 and solenoid 32, to the Fig.9 position Fig 9 shows the system of Fig.8 in the simultaneous (non independent) suspension operating mode The simultaneous suspension operation mode is made possible by the position of hydraulic valve 26 which interconnects the housings 1 8d and I 9d via hydraulic lines 24 with 27 and 25 with 28. This forms one hydraulic circuit as shown by the shaded area Therefore, a movement of piston rod 1 8a, in the direction of A, causes piston rod I 9a to replicate the movement of piston rod I 8a as indicated by B This is achieved by the piston I 8b pushing hydraulic fluid through the hydraulic lines 24 and 27, via damper block 18c and valve 26, to the underside of hydraulic piston I 9b, as indicated by the hydraulic flow arrows This simultaneously causes the top side of piston 19b to push hydraulic fluid through thehydraulic lines 28 and 25, via uauipei wocic. niu aiiu vaive ho, LU LIIC UHUCISIUC ui iiyuiauiic piston iou, as iiidmateu by the hydraulic flow arrows The movement of piston rod I 8a in the opposite direction of A will cause piston rod 19a to replicate this movement in the opposite direction to B Likewise, the movement of piston rod 19a in either direction will cause piston rod 1 8a to replicate the movement of piston rod 1 9a Although not depicted there will be appropiate seals between the piston rods 1 8a and I 9a and their respective housings I 8d and I 9d. Likewise, the hydraulic pistons 1 8b and 19b will have fitted to them seals that can act in both directions against the inside of their respective housings 1 8d and I 9d. Also not shown is the apparatus fitted to the damper block lSc and I 9c which controls the hydraulic flow to achieve the desired damping characteristics Within parameters suitable to the application the monitoring control unit 31 would activate and deactivate the hydraulic valve by an electric solenoid, or by another operating means, that is connected to axis 33 of valve 26 by a linkage (the linkage is not shown) The monitoring unit 31 would depend on data received from the hydraulic flow sensors 29 and 30 or/and by a manual signal. Other sensors could be incorporated within the system depending on the needs of the particular application The valve 26 could be manually activated by a lever connected to axis 33. The valve 26 could alternatively be turned to an interim position lying between those shown in Figs 8 and 9 to stop the flow of hydraulic fluid through the valve and thereby eliminate all suspension movement. Depending on the application the dampers 18 and 19 could be connected to the application via one end of each piston rod ISa and I 9a and their respective housings I 8d and I 9d, or both ends of each piston rod I 8a and I 9a and their respective housings I Sd and I 9d Alternatively, the pistons could have different surface areas to each other with the resulting trade-off between power and movement between the two or more pistons. A residual independent suspension movement could be incorporated by either the housings I 8d and 1 9d, or piston rods 1 8a and I 9b, or both being anchored via bushes suspended in rubber, or a similar material The invention is not limited to the vehicle's rear suspension but may also be applied to the vehicle's front suspension. The current invention when applied to both the front and rear suspension could be simultaneously activated by two valves 26 interconnected by one axis 33, perhaps combined in one unit, and operated by one solenoid 32 and one monitoring device 31.
The advantages of the current invention in relation to the vehicle are 1. The independent suspension movement of paired wheels can be locked 2. The total suspension movement of paired wheels can be locked 3 Advantages I & 2 can be mainly achieved with existing equipment which minimizes production costs 4 Due to 3 the addition to the unsprung mass is minimized Due to 3 the addition to the overall mass is minimized 6 Due to 3 the system requires a minimum of space
