The Hydraulic Steering Control Units consists of a rotary and a rotary meter. Via a steering column the steering unit is connected to the steering wheel of vehicle. When the steering wheel is turned, oil is directed from the steering system pump via the rotary valve and rotary meter to the cylinder ports L or R (depend on the direction of turn). The rotary meter the oil flow to the steering cylinder in proportion to the angular rotation of the steering wheel. The is used in steering low speed and heavy duty vehicles, such as engineering machinery、forklift、tractor、combine harvester and hydraulic rudder of ships. The advantages of the hydraulic steering control units;·Low cost, reliable.
·No load reaction on the steering wheel comfortable.
·Manual operation the steering wheel the pump doesn't work.·Low control torque, continuous operation.
·According to the system, different function and pressure level valves available.
- BHR1,BHR2,BHR3,BHR5 Hydraulic steering control units ( SCU)，new design, better performance.Widely applied to low speed and heavy loadvehicles E.g.construction machinary.forklift,tractor,harvester and helm contrlo etc.
BHR5 series is load sensing hydraulic steering control unit, it can be used with YXL priority valve for the load sensing hydraulic system. Characteristics:
.With good pressure compensation to the change of steering load.
. The flow and pressure of steering unit keep prior, steering function is reliable.
.The steering circuit and other circuits work independently of each other , thereby increasing the efficiency of the system ;.With high steering sensitivity, quick response, staring function is good in cold condition.
- BPB1,BPB2,BPB3,BPB5 Hydraulic steering control units(SCU) has similar structure with BHR1,BHR2,BHR3,BHR5,connecting dimension a little different,according to most European and US standard.
BPB5 series is load sensing hydraulic steering control unit, it can be used with YXL priority valve for the load sensing hydraulic system. Characteristics:
·With good pressure compensation to the change of steering load;
. The flow and pressure of steering unit keep prior, steering function is reliable;
. The steering circuit and other circuits work independently of each other , thereby increasing the efficiency of the system ;·With high steering sensitivity, quick response, staring function is good in cold condition.
- BPBS1,BPBS2,BPBS3 series hydraulic steering units has similar dimension with BPB1,BPB2,BPB3with relief valve,suction valve,inlet check valve integrated,and different valves can be assembled freely,compact,more convenient,according to European and US standards.
- BPBS5,BPBS5E,BPBS5L,BPBS5T,BPBS5TE series load sensing hydraulic steering control units are an important element in the load sensing steering system.Together with fixed displacement pump, various displacement pump with constant pressure or load sensing pump (variable displacement pump with flow，pressure joint compensated)supplying oil, it can make up different loading sensing hydraulic steering systems. BPBS5、BPBS5E、BPBS5L series load sensing steering control units adopt modulary mounting type, which can be used withVLSA* type priority valve via modulary mounting.
BPBS5T、BPBS5TE series load sensing steering control units adopt pipe mounting type, which can be used with DYXL, YXL type priority valve.
BPBS5E、BPBS5TE load sensing steering control units has EL electrical control port, and it is connected with L or R line. EL port is equipped with and electro-hydraulic relay to achieve hydraulic control system.
BPBS5L load sensing steering control units has LL electrical control port, and it is connected with LS line, LL port is equipped with and electro- hydraulic relay to achieve hydraulic control system.
