    A vehicle load sensing arrangement comprises an input arrangement to which is applied the force of a road spring and a control valve which may, for example, be a pressure reducing valve, having a movable valve member. A control spring acts in opposition to the road spring and together with a force-reduction arrangement serves to reduce the road spring force so that only a proportion of the road spring force is applied to the valve member the remainder being applied to the sprung part of the vehicle. To reduce the load and size of the control spring, and to thereby reduce the required installation space, the control spring is arranged between the valve member and the force-reduction arrangement and acts against the force transmitted by the force-reduction arrangement, so that the effective force acting on the valve member is the difference between the proportion of the road spring force transmitted by the force-reduction arrangement and the force of the control spring.

    The invention relates to devices for adjusting the pressure in the brake systems of vehicles depending on the axle load,
    The purpose of the invention is to increase the effectiveness of brake pressure regulation.
    The drawing shows a device for sensing a vehicle's load, a slit.
    The device contains a pressure regulator 1 having a housing 2 with an inlet 3, connected to the master brake cylinder, and an outlet port 4, connected to the brakes of the rear wheel of the vehicle. Stepped pa6o4jH Valve element 5 is mounted tightly slidable in the bore 6 in the housing and has a valve head 7 that is engaged with one side of the valve seat 8 to interrupt the connection between the inlet and the outlet
    In normal operation, element 5 is subjected to an upward axial force. Fluid from the inlet 3 passes through the valve head 7 to the outlet hole until the switching pressure is reached, at which the pressure force on the element 5 exceeds the axial force to move the valve head 7 from the seat 8 and does not close the valve. A further increase in entrance corpus. Gasket 17 prevents access of dirt and moisture to housing 2,
    The housing part 10 has a stepped through hole 18, in the lower part of which, being a hole of a larger diameter, there is a block 19 made of rubber or other elastic material that contacts its bottom surface with the plate 20. The plate 20 has a notch 21 in which the ball is installed I) 5. With its upper surface, the block 19 engages with a cylindrical bucket-like. Transmitting force element.
    15 22. The lower end of the rod 23 enters the element 22 and is in contact with its lower part, and the upper end enters the notch 24 of the element 5 The transmitting force element 22 moves downward
    20, of the aid of the control spring 25 placed between the support surface of the upper part 9 of the body and the seat 26 which engages with the upper end of the force transmitting element 22,
    25 During operation, the spring force 13 is transmitted through a cut. Cup-shaped support surface 14 and the ball 16 to the rubber block 19. The block 19 enters a portion of the hole 18 having a smaller
    30 diameter, and acts as a force reducer transmitted to the element 22, transmitting a force that is proportional to the force of the spring displacement of the element 5, to change the flow between the inlet and outlet openings.
    The housing 2 is made of two parts 9 and 10, fastened with the help of a tubular holding element 11, and is attached to the frame 12 of the sprung part of the vehicle.
    us ,. this proportion depends on
    foot pressure causes a reciprocating pos. the cross sections of the sections are holes 8. The rest of the force
    the barriers 13 are transmitted through the body 2 to the frame 12 of the vehicle. The effective axial force is applied by the rod 40 and thus to the valve element 5, the axial force being the difference between, the force directed to and being applied to the force-transmitting element 22, and the force 4S Right down and applied by the control spring 25 . Upper part of spring I3 springs
    is installed against the cup-shaped support surface 14, at the upper end of which there is a circular elastic shock absorber, 15, the inlet of the PDS engages with the frame 12 of the vehicle and specifies the lateral direction of the support surface 14. At the base of the support surface 14 there is a surface in contact with the ball 16 which is held by a rubber gasket .1.7 attached to the bottom of the bottom 10
    This axial force, which determines the operating characteristics of the regulator 1, thus depends on 50 the force of the spring 13, which, in turn, depends on the load of the vehicle and on the pre-stress of the control spring 25.
    Due to the fact that the control spring 25 resists only a part of the force of the spring 13, it may be less, which leads accordingly. STV skinny benefits.

    enclosures. Gasket 17 prevents access of dirt and moisture to housing 2,
    The housing part 10 has a stepped through hole 18, in the lower part of which, representing a hole of a larger diameter, is located. a block 19 of rubber or other elastic material that contacts its lower surface with the plate 20. The plate 20 has a recess 21, in which the ball I) 5 is installed. With its upper surface, the block 19 engages with a cylindrical bucket-like. Transmitting force element.
    22. The lower end of the rod 23 enters the element 22 and is in contact with its lower part, and the upper end enters the notch 24 of the element 5 The transmitting force element 22 moves downward
    the aid of the control spring 25 placed between the support surface of the upper part 9 of the body and the seat 26 which engages with the upper end of the force transmitting element 22,
    During operation, the force of the spring 13 is transmitted through the cut cup-shaped support surface 14 and the ball 16 to the rubber block 19. The block 19 enters the portion of the hole 18 having a smaller
    diameter, and acts as a force reducer transmitted to the element 22, transmitting a force that is proportional to the spring force. The specified axial force that determines the operating characteristics of the regulator 1, thus, depends on 50 spring force 13, which, in turn, - the speed depends on the load of the vehicle and on the prestressing of the control spring 25.
    Due to the fact that the control spring 25 provides resistance only to a portion of the force of the spring 13, it may be less, which brings about corresponding meager advantages.
