Abstract
The present invention discloses a liquid pressure control device (1) for load responding brake. This liquid pressure control device (1) comprises valve mechanisms (5) and (6) for reducing liquid pressure from a brake master cylinder and transmitting reduced liquid pressure to rear wheel brake cylinders, these operations being performed by opening/closing valves with a pair of plungers (3) and (4) which respond to loads independently of each other by the liquid pressure from the brake master cylinder, and a load sensing mechanism (11) for moving the pressure reducing operation starting points of the valve mechanisms (5) and (6) by applying loads to the plungers according to the movable load amount of a vehicle. A recessed section (14b) is formed in a portion of an equalizer (14) brought into contact with a load sensing lever (13), and a buffer member (19a) made of an elastic material is fixed in this recessed section (14b). During non-operation, the equalizer (14) and the load sensing lever (13) are kept away from each other by the buffer member (19a). During operation, by pressing and deforming the buffer member (19a) with the load sensing lever (13), direct contact is made between the equalizer (14) and the load sensing lever (13). Thus, hitting sounds produced from the load sensing mechanism can be prevented at the time of a sudden brake operation or brake non-operation during traveling of the vehicle, and the durability of the used buffer member can be improved.
