The utility model discloses a rotary valve type integral power steering device for automobiles, belonging to automobile steering system. The rotary valve type integral power steering device realizes power steering by screw bolts, recirculating ball nuts, a geared sector, an upper cover and a rotary valve which are arranged inside a shell. With the advantages of reasonable design, advanced technology, compact structure, small size, easy manufacturing, low cost, large output torque and favorable returnability, the utility model is applied to various automobiles and other transport vehicles whose steering shaft load is smaller than 10 ton.
Description
The utility model belongs to a kind of automobile steering valve integral power deflector in the automotive steering, is applicable to that steering shaft load is less than various automobiles and other transport vehicle of 10 tons.
At present, in China's auto trade, load carrying ability below 10 tons bogie and the deflector of uses such as motorcoach, trackless trolley car generally all be to follow the deflector of bad shot nut type.This deflector is backward in technique, poor performance, navigating mate operation effort.In addition, also having small part is separated type or semi-integral power steering device.This deflector also belongs to structure and falls behind, poor-performing and cost height, and volume is big.
In recent years, China had introduced external power steering technology.Introduce U.S. TRW Ltd. (US) One Space Park, Redondo Beach CA 90278 U.S.A. steering valve power steering technology as Second Automobile Works, Chongqing heavy motor vehicle originating firm is introduced West Germany ZF company side valve type power and is shifted to the device technology.But the power steering complex structure of introducing, difficulty of processing is big, and the manufacturing cost height is incompatible with China current auto-industry technical merit.
In order to satisfy the demand of China's auto trade to power steering, solve the existing shortcoming of above-mentioned deflector, need a kind of power steering that is suitable for the current auto-industry technical merit of China.The utility model is exactly for realizing the deflector of a kind of automobile steering valve of this purpose design-calculated integral power.
The utility model is by installation screw rod (2) in housing (1), follows bad shot nut (3), tooth fan (4), and loam cake (7) and rotary valve (33) are realized power steering.
Concrete technical characterictic is:
One end of screw rod (2) is porose vertically, make it to play the effect of rotary valve valve body (8), four holes are arranged on the garden side face of valve body (8), its mesopore (14), (15) be fuel feed hole, hole (16), (17) be fuel return hole, hole (16) have back leakage groove (22) on (27), (23), have the oil groove (18) that leads to the B chamber between hole (16) and hole (14), have the oil groove (19) that leads to the B chamber between hole (15) and hole (17), have the oil groove (20) that leads to the A chamber between hole (16) and hole (15), have the oil groove (21) that leads to the A chamber between hole (14) and hole (17), valve body (8) axial end has two positive stop lug boss (24).
Spool (10) matches with valve body (8), spool (10) one end garden side faces have eight oil ducts (25) and wherein have oil groove (26) on four oil ducts, other end garden side face has spline (29), and the shaft shoulder (27) has two concave stations (28) to match with valve body (8) positive stop lug boss (24).
Spacer (5) is enclosed within on the valve body (8), the through hole (29) of spacer (5) garden side face and the hole (14) of valve body (8), (15) communicate, the through hole (30) of spacer (5) garden side face and the oil groove (20) of valve body (8), (21) phase through hole (29) and hole (30) not at grade, the vertical axis in two holes differs 45.
Torsion bar (11) inserts in the spool (10), pin (9) is fixed together an end of torsion bar (11) and spool (10), pin (6) is fixed together the other end of torsion bar (11) and valve body (8) and spacer (5), has one section diameter thinner than bar both ends in the middle of the torsion bar.The effect of torsion bar is when cancellation external force, leans on the distortion elasticity of itself that spool (10) is automatically reset.
Protecgulum (7) porose (12), (13), its mesopore (12) is a fuel return hole, an end connects the fuel tank (not shown), and the oil groove (22) of the other end and valve body (8), (23) communicate; Hole (13) is a fuel feed hole, and an end connects the oil pump (not shown), and the other end communicates with the hole (29) of spacer (5).When the automobile straight-line travelling, enter hole (14) from the oil of oil pump by hole (13), (15), and then again through via hole (16), (17) and back leakage groove (22), (23) get back to fuel tank.When motor turning, torsion bar (11) rotates together with spool (10) and elastic deformation takes place, at this moment the oil from oil pump enters hole (30) and oil groove (20) by hole (13), (21) arrive the A chamber, perhaps enter oil groove (18) by hole (13), (19) arrive the B chamber, thereby realize that promoting to follow bad shot nut (3) with fluid power finishes the motor turning task.In order to limit the stroke of recirculating ball nut (3), on housing (1) and protecgulum (7), position-limited lever (31) is installed, (32).Position-limited lever is connected A by backing down check valve (34) (35), and off-load is realized in B two chambeies.
Major advantage of the present utility model is: owing to adopt rotary value type integral power steering unit, thus reasonable in design, advanced technology, compact conformation, volume is little, handling ease, low cost of manufacture, output torque is big, and returnability is good, work safety, use and maintenance is convenient.
