933,581. Controlling lateral canting. DAIMLER-BENZ A.G. April 4, 1962 [April 7, 1961], No. 13037/62. Class 108(2). A vehicle roll stabilizer for each pair of wheels comprises a divided transverse torsion bar the inner ends of the parts 7, 8 of which are interconnected by a fluid pressure servo-motor, for producing differential rotation of the torsion bar ends to reduce body roll, and is characterized by the provision of locking means releasable by fluid pressure only when the fluid pressure is adequate to operate the motor. The motor casing 4, Fig. 2, has two radial walls 15 (Fig. 4) and is splined to torsion bar part 7 and rotor 13 has two radial vanes 13<SP>1</SP> and forms the inner end of torsion bar part 8. The opposite pairs of chambers 16-19 formed between the vanes 13<SP>1</SP> and walls 15, are interconnected. Provided in the rotor 13 and separated by wall 3, Fig. 3, are two aligned peripheral grooves, the ends 43a, 43b of which are engaged by radial pins 46, 47 in bores in casing 4. To rotate rotor 13 clockwise relative to casing 4 chambers 17, 19 are connected to a fluid pressure source and chambers 16, 18 are connected to exhaust. Pin 46 prevents rotation until it is raised from groove 43 against the bias of spring 48 by fluid pressure communicated through bores 58, 60, 62 in the rotor from chamber 17. Fluid from the outer end of bore 50 escapes through passage 55 (Fig. 2) and chamber 16 to exhaust. The angle of rotation is limited by abutment of pin 47 with wall 3. To permit anticlockwise rotation of rotor 13 pin 47 is raised by pressure fluid communicated through bores 59, 61, 63 acting on the lower end of pin 47. The bias of springs 48 is adjustable by threaded plugs 49. The operation of the servomotor 4 may be controlled by the steering or be dependent upon centrifugal force on the vehicle and the vehicle wheels may be air sprung. Reference has been directed by the Comptroller to Specification 895,095. |
