An adjustable pressure simulator apparatus (40) for a brake-by-wire vehicle brake system includes: a damper body enclosing a first cylinder and a second cylinder in fluid communication with each other and at least partially filled with fluid, where the first cylinder houses a first piston, and the second cylinder houses a second piston; the first cylinder accommodates a first piston subjected to the thrust of the fluid and biased by a first resilient means that resists the thrust exerted by the fluid (until reaching a first primary end stop), and wherein the second cylinder accommodates a second piston subjected to the thrust of the fluid and biased by a second resilient means that resists the thrust exerted by the fluid (until reaching a second primary end stop), the second elastic device resists the thrust exerted by the fluid (until reaching the secondary end stop), and the first elastic device and the second elastic device have different rigidities to cause displacement of the second piston only after reaching a predetermined stroke of the first piston under the thrust of the fluid.

    一种用于线控制动型车辆制动系统的可调节压力模拟器装置(40)包括:缓冲器本体,缓冲器本体对第一缸体和第二缸体进行围封,第一缸体和第二缸体彼此流体连通并至少部分地填充有流体,其中,第一缸体容置第一活塞,第一活塞经受所述流体的推力作用并被第一弹性器件偏置,第一弹性器件抵抗由所述流体施加的所述推力作用(直到到达第一初级端部止挡件),其中,第二缸体容置第二活塞,第二活塞经受所述流体的推力作用并被第二弹性器件偏置,第二弹性器件抵抗由所述流体施加的推力作用(直到到达次级端部止挡件),其中,第一弹性器件和第二弹性器件具有不同的刚度,以在所述流体的推力作用下仅在达到第一活塞的预定冲程之后才引起第二活塞的移位。
