Embodiment
To make the technical problems to be solved in the utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And specific embodiment is described in detail.
There is provided a kind of circulating ball the problem of extreme position is also easy to produce noise for existing steering gear for the utility model
Formula steering assembly and automobile.
As shown in figure 1, embodiment of the present utility model provides a kind of recirculating ball-type steering assembly, including：Steering gear
Steering gear piston 2 is provided with housing 1, the steering gear housing 1；The two ends of the steering gear piston 2 are elastic with first respectively
The elastic spacing device 4 of limiter 3 and second is in contact, and the first elastic spacing device 3 is fixedly installed at the steering gear housing
On body 1；The first end of the second elastic spacing device 4 is in contact with the steering gear piston 2, the second elastic spacing device 4
The second end be connected with a steering gear screw rod mounting seat 5, the steering gear screw rod mounting seat 5 is fixedly mounted on the steering gear
In housing 1；Steering gear screw rod 6 is installed, the steering gear screw rod 6 passes through described second in the steering gear screw rod mounting seat 5
Elastic spacing device 4, is plugged in the inside of the steering gear piston 2, with the threaded engagement of steering gear piston 2.
Recirculating ball-type steering assembly described in above-described embodiment of the present utility model passes through in ball-and-nut steering gear or so
End face increase elastic device, by the device be arranged on ball-and-nut steering gear left and right end face, when enter in steering procedure limit by row position
When putting, elastic device shifts to an earlier date and piston contact, slows down the translational speed of piston, so also slow down the speed of steering wheel rotation,
This also causes speed of the valve port of rotary valve when opening to slow down, and liquid stream is instantaneously reduced by flow velocity during the valve port of steering gear rotary valve,
Improve the problem of liquid stream is by the generation liquid stream noise of steering gear valve port；Simultaneously the elastic device also to extreme position when have prompting
Effect, the i.e. velocity of rotation close to extreme position steering wheel decline, and hand-power increase, have prompting to steering extreme position
Effect.
Wherein, the first elastic spacing device 3 and the second elastic spacing device 4 include a check ring 7 and a limit
Position spring 8, the limit spring 8 is positioned close to the side of the steering gear piston 2.
Wherein, the check ring 7 on the first elastic spacing device 3 is fixedly mounted on the steering gear housing 1, described
Check ring 7 on second elastic spacing device 4 is fixedly mounted in steering gear screw rod mounting seat 5.
Wherein, the limit spring 8 is arranged in the check ring 7, is interference fitted with the check ring 7.
Wherein, the steering gear screw rod 6 is rotated, and drives the steering gear piston 2 back and forth to be transported in the steering gear housing 1
It is dynamic.
The first elastic spacing device 3 and the second elastic spacing device 4 described in above-described embodiment of the present utility model are wrapped
A check ring 7 and a limit spring 8 are included, the check ring 7 and the limit spring 8 are interference fitted, and the spacing bullet
The setting of the compression stress of spring 8 can carry out the selection of different-diameter spring according to vehicle demand, specifically depending on vehicle own situation,
It is described in the rotation process of steering gear screw rod 6 by increasing elastic device in the end face of the left and right of steering gear piston 2 two
Steering gear screw rod 6 drives steering gear piston 2 to move, when close to extreme position, the limit spring 8 and the steering gear piston
2 are contacted the translational speed for slowing down the steering gear piston 2 progressively, with the decrement increase of the limit spring 8, institute
The translational speed for stating steering gear piston 2 stops when being reduced to extreme position, and valve port of rotary valve of steering gear is opened during this
The time length of side, can cause liquid stream to be unlikely to produce the noise of hydraulic pressure when flowing through the valve port of rotary valve, improve steering gear extreme position
When hydraulic pressure noise situation, in addition steering gear close to during extreme position due to piston translational speed reduce, so for
The strike note of extreme position stopping means can also be cut down, while also functioning to protective effect, the i.e. limit to the part of steering gear
The moving resistance of piston during position is increased, and driver plays the speed reduction in direction, points out driver to turn to extreme position,
By the structure for the extreme position for optimizing steering gear, increase elastic device, the noise of liquid stream when improving steering gear extreme position
Strike note and the transmission of impact with extreme position.
Embodiment of the present utility model additionally provides a kind of automobile, including the recirculating ball-type steering described in above-described embodiment
Assembly.
Recirculating ball-type steering assembly and automobile described in above-described embodiment of the present utility model in circulating ball by turning to
Device left and right ends increase elastic device, improve steering gear extreme position when steering gear extreme position when liquid stream noise and strike note
Sound, the device pass through steering gear left and right end portions increase elastic device so that when steering gear is diverted to extreme position the structure with
The end contact of steering gear piston 2, because spring is denatured so that steering gear is dropped close to translational speed during extreme position
Low, as spring is gradually compressed, the translational speed of piston is with gradually reducing, so the device is by extending contact time
Come the opening time of the valve port that improves steering gear rotary valve, so that when liquid flows through rotary valve when improving the extreme position of steering gear
The possibility of raw noise, liquid stream is slowed down by the speed of valve port, and abnormal sound eliminates the satisfaction for adding customer, while to turning
Certain protective effect can be also played to the extreme position of device, the reliability of product is added, the structure is intended to increase by end face
Plus buffer unit improves steering gear or so end face elastic device structure, when improving steering gear extreme position the noise of liquid stream and
The strike note of extreme position and the transmission of impact.
Described above is preferred embodiment of the present utility model, it is noted that for the ordinary skill of the art
For personnel, on the premise of principle described in the utility model is not departed from, some improvements and modifications can also be made, these improvement
Protection domain of the present utility model is also should be regarded as with retouching.
