Patent number: 11274697Abstract: Collapsible discs move towards or away from each other in embodiments of the disclosed technology by changing the angle of flanges which connect the two discs together. The flanges connect to each respective disc by way of one a fixed connection to one disc and a slidable connection to the other. The flanges slide into portals in the bottom disc and then extend along and into a hollow space therein the bottom disc. The flanges have a tip or multiple tips which is/are wider than a rest of an elongated length thereof which frictionally holds the flanges, and therefore, the discs in places until the discs are rotated causing the flanges to be pulled out from or pushed into the portals. This, in turn, causes the discs to move closer together or become further apart in embodiments of the disclosed technology.Type: GrantFiled: March 15, 2019Date of Patent: March 15, 2022Inventor: Ikey Srour

Patent number: 11161488Abstract: An EH braking system including a brake valve operably connected to a brake and a brake pressure sensor. A calibration event for the EH braking system where the compliance calibration time is measured from when the brake valve is operated at full activation to when the brake pressure sensor senses the pressure starts to build in the brake circuit. The compliance calibration time is the time it takes to fill the compliance volume of the brake(s). The compliance calibrated fill time is used during a normal braking event wherein the brake valve will be operated to a full activation condition for duration of the compliance calibration time. After the calibrated fill time has elapsed, the brake valve will be operated at the desired operator command of the brake pedal. This results in quicker fill times of the brake and better brake system response.Type: GrantFiled: October 30, 2019Date of Patent: November 2, 2021Assignee: DEERE & COMPANYInventor: Scott R. Stahle

Patent number: 11148653Abstract: The present invention relates to a method for avoiding excess pressures in a pressure medium circuit of an electronically slip-controllable braking system in the event of a decline of an intrinsic elasticity of the braking system and an electronically slip-controllable braking system. Electronic control units, ascertain a setpoint value for a delivery volume of the pressure generator of these braking systems and convert it into an activation signal for the drive of the pressure generator. In dependence on the prevailing elasticity of the pressure medium circuit, a pressure gradient is established, using which the pressure in the pressure medium circuit changes over time. The ascertainment of an activation signal for the drive of the pressure generator by the electronic control unit is based on the established pressure gradient.Type: GrantFiled: July 16, 2019Date of Patent: October 19, 2021Assignee: Robert Bosch GmbHInventors: Bertram Foitzik, Daniel Frank
