Plate stroke (realizes throw of lever) in hand brake.The main braking cylinder is used as when external force manipulates is used for hydraulic brake pressure
Rated value setting side, the hydraulic brake pressure do not utilize the main braking cylinder to generate, but utilizes external energy, for example sharp
It is generated with hydraulic pump.The main braking cylinder when for example by closing seperating vale outer force braking or will be with the vehicle system
Dynamic system hydraulically separates, and brake fluid is expressed in the pedal travel simulator when manipulating the main braking cylinder.
The piston and piston spring that pedal travel simulator usually has cylinder and can move in the cylinder, the piston
Spring is resisted using the manipulation of the motor vehicle braking system of main braking cylinder and loads the piston in a return direction.The pedal row
Journey simulator will be connect or hydraulically when external force manipulates a motor vehicle braking system with main braking cylinder, which is grasping
Vertical to be at that time expressed to brake fluid in the cylinder of the pedal travel simulator, thus the piston resists the spring of the piston spring
Power and moved in the cylinder on the forward stroke direction contrary with the backhaul.
Summary of the invention
The pedal travel simulator of feature according to the present invention, with claim 1 has resilient frictional element, such as
The disk or body that elastomer is constituted, in the cylinder of the pedal travel simulator, which is especially arranged in the work
Between plug and the piston spring.Under any circumstance, the resilient frictional element is in piston stroke all in stroke direction
It is moved in the cylinder, wherein the stroke of the friction element can have the length different from the piston stroke.Preferably,
The resilient frictional element is connect with the piston, with the piston motion and implements stroke identical with the piston.
By the piston to the pressure-loaded of the resilient frictional element, the resilient frictional element is compressed in the stroke direction,
Thus the resilient frictional element is expanded transverse to the stroke direction.Pressure-loaded refers herein to be applied by the piston
The power being added on the surface of the friction element.
The shape and size of the resilient frictional element are so mutually coordinated with the cylinder of the pedal travel simulator, so that the elasticity
Friction element is when it is expanded transverse to the stroke direction from the internal side for being pressed against the cylinder.The side of the cylinder is the one of the cylinder
A or multiple inner surfaces, the inner surface stretch in the stroke direction and preferably in the stroke direction with can
Mobile mode guides the piston.The friction element can stick on this in inside in a manner of unsupported and is undeformed
At the side of the cylinder of pedal travel simulator.In this case, make the friction element by compressing friction element raising
Power from the internal side for being pressed against the cylinder.Preferably, when the resilient frictional element is unsupported and undeformed, which rubs
Wiping element does not stick on or not at the cylinder at the cylinder or only at one week internal side position.In this case,
When the resilient frictional element is compressed, it is just clinged at the cylinder in inside.Under any circumstance, when the elasticity is rubbed
When wiping element by compressing the side for being pressed against the cylinder from inside, which all generates makes in two stroke directions
Move the friction of the friction element and the piston stroke.The friction is improved with the pressure-loaded by the piston,
The pressure-loaded compresses the resilient frictional element.
By the resilient frictional element, pedal travel simulator according to the present invention has dynamic lag, that is to say, that
The hydraulic pressure that the piston is loaded in the cylinder of the pedal travel simulator is bigger than in backhaul in forward stroke.Due to
When pressure is higher it is described compression and therefore friction it is bigger, therefore, when the hydraulic pressure in the cylinder in the pedal travel simulator more
Gao Shi, the pressure difference between forward stroke and backhaul are bigger.
