Patent number: 11255390Abstract: A brake caliper is fastened to a stationary brake carrier by two fastening elements such that the caliper can slide axially relative to the brake disc. The fastening elements each have a guide bar fixedly connected to the brake carrier, of which guide bars, one guide bar is guided as a fixed bearing and the other guide bar is guided in a plain bearing, which is designed as a floating bearing having a floating bearing axis. The floating bearing has a guide bush, which reaches around the guide bar and is retained in a caliper bore such that sliding is prevented. A first tubular, variable-length seal is arranged on the end region of the guide bar far from the brake disc, which seals the guide bar from the environment and is fastened on the guide bar and in the guide bush. The first tubular, variable-length seal is clamped on the guide bar by a cap pressed into the guide bar.Type: GrantFiled: October 23, 2019Date of Patent: February 22, 2022Assignee: KNORR-BREMSE Systeme fuer Nutzfahrzeuge GmbHInventors: Rudolf Fischer, Martin Seidl

Patent number: 10031185Abstract: Determining a state of charge (SOC) of a rechargeable battery includes using a first process to determine a first value for the SOC of the battery and using a second process to determine a second value for the SOC of the battery and deriving the SOC as a weighted average of the first value for the SOC and the second value for the SOC. During a charging cycle of the battery an input charge of the battery is determined from an input current flowing into the battery and a charging time. During a discharging cycle an output charge of the battery is determined from an output current flowing out of the battery, a discharging time and an actual capacity of the battery is the sum of the input charge over charging cycles minus the sum of the output charge over discharging cycles.Type: GrantFiled: February 4, 2014Date of Patent: July 24, 2018Assignee: EXIDE TECHNOLOGIESInventors: Rainer Bussar, Gerd Wessels Hoogestraat, Wolfgang Rudolf Fischer, Thomas Hopper, Nicolas Henri Bernard Redon, Olaf Sielemann, Sebastian Zeh
