Description
Technical field
The utility model belongs to the technical field of communications and transportation, is specifically related to a kind of parallel hydraulic servo steering system.
Background technology
At present, in car load driving process, there is the safety problem of some control aspects in the hydraulic power-assisted steering parallel system of hybrid power bus.On the one hand, meet engine off condition when low vehicle speeds, control engine off, then control to start electric hydraulic power-assisted steering; On the other hand, when needing engine to start when the pure electrical travelling of vehicle is sailed, control assist motor and shut down, then start the engine.Because power-steering closedown and unlatching have certain response time, steering swivel system in parallel is without power steering during both switch, and there is great potential safety hazard, easily causes serious traffic accident, even car crash.
Utility model content
For solving the deficiency of above-mentioned prior art, the purpose of this utility model is to provide a kind of safety switching apparatus of hydraulic power-assisted steering.
Invention thinking of the present utility model shows as: save the switching time that power steering is closed and opened, safer, convenient, fast.
A kind of parallel hydraulic servo steering system, comprise conventional hydraulic servo steering system oil circuit and electric hydraulic power-assisted steering system oil circuit, and the steering box be connected, steering oil reservoir, described conventional hydraulic servo steering system oil circuit comprises oil pump for engine, described electric hydraulic power-assisted steering system oil circuit comprises electric-motor pump, described oil pump for engine one end is connected with steering oil reservoir by T-pipe joint with described electric-motor pump one end, the described oil pump for engine other end is connected with steering box by T-pipe joint with the other end of described electric-motor pump, check valve A is respectively arranged with between the other end of the described oil pump for engine other end and described electric-motor pump and T-pipe joint, check valve B.
Described electric hydraulic power-assisted steering system oil circuit also comprises the frequency converter that one end is connected with described electric-motor pump.
The described frequency converter other end is connected with electric power distribution cabinet.
Described electric power distribution cabinet is also connected with high voltage power battery and electric machine controller, and described electric machine controller is connected with entire car controller.
During utility model works, should before engine off, first started by electric-motor pump, electric-motor pump reaches to be expected after rotating speed, again by engine off, when needing start the engine, first by engine starting, to be shut down by electric-motor pump when driving engine reaches certain rotating speed again.Meanwhile, the electric machine controller moment is detected, if send breakdown signal to entire car controller by CAN when breaking down, and vehicle control unit controls engine starting.So guarantee power steering reliability service in the process of moving.
The beneficial effects of the utility model:
1, control is simple, steering swivel system is safe and reliable.
2, engine power is saved.
3, oil consumption is reduced.
