Introduction of Parker bus and truck hydraulic system solutions
Introduction of Parker bus and truck hydraulic system solutions
In November 26, 2014, Shanghai BMW exhibition, Parker Hannifin Corporation held a "solution" pike buses and trucks hydraulic system seminar. The chapter Yisheng Dr. speech. The meeting is divided into four main parts: Parker introduction, Parker hydraulic transmission technology, customer experience and Parker third generation hydraulic transmission technology.
Parker introduction
Now, Parker group is divided into 7 groups: aerospace group, fluid connection device group, hydraulic group, instrument and meter group, automation group, sealing material and equipment group, CITS group. Parker powertrain is a global leader in hydraulic transmission technology, headquartered in Columbo, Ohio, USA. The aim of pike company is to solve the most challenging engineering problem in the world. The company has many customers worldwide.
Parker hydraulic transmission technology
Why do you like Parker's hydraulic gearbox so much? 1, the product has no torque converter loss. 2, power density is much higher than electrical products. 3, it can be combined with braking energy recovery: rapid absorption and release of energy. 4, has unique system design allows: more braking energy recovery: 71% hydraulic vs.21% oil and electricity; engine more time running at the best point: automatic transmission. 5, have mature and reliable core technology.
How does Parker's power split gearbox work? In the high speed state, the output coupling power split is used, and the input shaft power is ~100% power transmitted by mechanical transmission.
In acceleration mode, there are two power paths for engine drive. In deceleration mode, energy recovery mode.
What are the advantages of Parker power split structure?
Start stop of vehicle:
1. Maximize energy recovery
2. Optimization of engine operation
3, advanced engine stop function
Long time high speed travel:
1. Stepless speed change allows engine operation optimization
2. Most of the energy is transmitted by efficient mechanical means.
User experience:
In heavy vehicles, 1, more than 150 vehicles serve a number of municipal and private fleets. 2, the normal running time of the fleet is higher than 97%. 3, has accumulated more than 140000 hours and 2000000 kilometers of reliable service.
In medium-sized cars, the advanced engine stop function can shut down the engine under any circumstances: 1, vehicle stop, 2, vehicle deceleration, 3, vehicle acceleration (high pressure accumulator hydraulic exceeds a certain limit).
Customer field test results for Parker hydraulic transmission technology can reduce fuel consumption 35~55%, every year the car can reduce greenhouse gas including CO2, COX, NOX, THC and other emissions 38~55 tons, improve the productivity of 5~15% for customers. The braking system is only changed once in the service life of the vehicle, which greatly reduces the maintenance cost. Parker hydraulic transmissions also bring better start acceleration, new heel, smooth shift, and superior braking performance.
Parker third generation hydraulic transmission technology:
The third generation of products will bring the first cost-effective solution to reduce fuel consumption and exhaust emissions for the bus market.
The third generation applies to the gross vehicle weight up to 19000kg/42000lbs
Engine power and torque up to 300HP/600ft-lb
It can be matched with a variety of fuel type engines with advanced engine stop function
Low cost basic and selectable functions: 1, ultra high performance (2 forward) 2, providing equal forward and backward torque (F-N-R)
Similar to the size of traditional medium sized car transmissions
Only one high-pressure oil pipe is connected with a low-pressure oil pipe and an energy recovery device, and two low pressure oil pipes are connected to the radiator
It is easy to install on different chassis
