Abstract
A hydraulic power assisted steering gear of an automobile, which comprises a dynamical steering gear, a hydraulic oil pump and an oil storing device, wherein, the dynamical steering gear, the hydraulic oil pump and the oil storing device are communicated through oil pipes; the pipes communicating with the dynamical steering gear, the hydraulic oil pump and the oil storing device are connected in series with oil coolers. The hydraulic power assisted steering gear is used for transportation mechanisms such as automobiles, and the like. Compared with the prior art, the hydraulic power assisted steering gear can control and prevent the excess temperature rise of hydraulic oil, improve the operation reliability of a device, ensure the running safety and extends the service lives of the oil pump and the steering gear at the same time.
Description
Technical field
The utility model relates to the Transport Machinery technical field, especially a kind of device that auxiliary power is provided for the deflector of Transport Machinery such as automobile by hydraulic efficiency gear.
Background technology
Existing hydraulic pressure assisted steering device is mostly by oil pipe bonded assembly power steering, hydraulic oil pump, oil chamber be contained in their in-to-in hydraulic oil and constitute.Hydraulic oil provides power through hydraulic oil pump pressurization back to power steering.Be contained in this automobile hydraulic electric power steering device on the Transport Machinery such as automobile when working long hours, when especially long-time high load capacity is worked, the energy of hydraulic oil pump input and the heat transmission of mechanical engine can make the hydraulic fluid temperature in the hydraguide raise, should the oil temperature when serious can be up to more than 90 degrees centigrade, at this time the hydraguide mode of operation is damaged, delivery pressure can take place and descend in hydraulic oil pump under the oily temperature mode of operation of height, flow reduces, the phenomenon of fuel feeding not even, power steering usefulness is weakened even lost efficacy, driving turns to the effort that becomes, even is difficult to turn to by manpower, therefore can produce traffic safety hidden danger.
Summary of the invention
The utility model provides a kind of automobile hydraulic electric power steering device, and it mainly solves prior art too high problem of its hydraulic oil temperature rise when long-time, high capacity work.
In order to address the above problem, the technical scheme that the utility model adopted is: include the power steering, hydraulic oil pump and the oil chamber that are communicated with by oil pipe, be connected with oil cooler on the pipeline that is communicated with described oil chamber, described power steering and described hydraulic oil pump.
In the technique scheme, described oil cooler can be the heat exchanger that is externally connected with cooling fins at oil pipe, also can be at the heat exchanger of oil circuit through the hollow cooling fins, this cooling fins is equipped with cooling fan outward, described oil cooler can also be the heat exchanger that oil pipe passes coolant storage tank, this coolant storage tank can be located on the outer wall of described oil chamber, and described oil cooler can be connected between described oil chamber and the described power steering.
Owing to adopt technique scheme, the utility model compared with prior art, the beneficial effect that has is: owing to be connected with oil cooler on the pipeline that is communicated with described oil chamber, described power steering and described hydraulic oil pump, make hydraulic oil after the subcooler cooling, resupply hydraulic oil pump, can control and prevent the excessive rising of hydraulic oil temperature, improve the device reliability of operation, guarantee traffic safety, can also prolong the service life of oil pump and direction machine simultaneously.
