Abstract
The utility model discloses a shell structure of an automobile steering device. The shell structure of the automobile steering device is formed by a first shell body (1), a second shell body (2) and a connecting shaft (3) arranged between the first shell body (1) and the second shell body (2) in a press fitting mode. A rack shell (2a), a rack shell (2b) and an adjusting screw installation hole (2c) are arranged on the second shell body (2), wherein the axes of the rack shell (2a) and the rack shell (2b) are perpendicular to each other. The rack shell (2a) and a connecting shaft (3) are arranged coaxially, the rack shell (2b) is arranged above the rack shell (2a), and the adjusting screw installation hole (2c) is arranged right in front of the rack shell (2a). Anti-rotating blocks (4) are fixedly sleeved on the first shell body (1) and the second shell body (2), the periphery of each anti-rotating block (4) is formed by an upper plane (4a), a rear plane (4b), a lower plane and a front cambered surface (4c) in a surrounding mode, and the anti-rotating blocks (4) are made of aluminum alloy. Due to the fact that the anti-rotating blocks are arranged on the shell bodies of the steering device, the shell structure of the automobile steering device effectively solves the problem of the rotating of the shell bodies of the steering device, is simple in structure, ingenious in conception, and easy to achieve.
Description
Technical field
The utility model relates to the automobile steering device part, is specifically related to a kind of pinion and-rack automobile steering device housing structure.
Background technology
Rack and pinion steering gear generally includes steering gear housing, gear, tooth bar, adjustment screw and tooth bar guide block, and the deflector gear meshes with steering rack in the lower end that turns to main shaft.When the rotation bearing circle, the gear in the deflector just rotates, and the tooth bar in the drive deflector moves towards the direction of rotating of steering wheel.The action of steering gear rack by steering gear rack termination and steering track rod termination, is delivered on the track arm, thereby turns a wheel.In deflector, steering gear housing is used for support and fixed gear wheel, tooth bar.
Automobile steering device housing structure as shown in Figure 1, by the first housing 1, the second housing 2 and be arranged on the first housing 1 and the second housing 2 between adapter shaft 3 press-fit and form, be respectively installed with gum cover 5 on the first housing 1 and the second housing 2.Be provided with tooth bar shell 2a, gear hub 2b and set screw mounting hole 2c on the second housing 2, three's axis is mutually vertical.Tooth bar shell 2a and adapter shaft 3 coaxial settings, gear hub 2b be positioned at tooth bar shell 2a directly over, set screw mounting hole 2c is positioned at the dead ahead of tooth bar shell 2a.For preventing steering gear housing rotation, below the second housing 2, be extended with fixed installation journal stirrup 2d, be bolted carry out spacing.It is one-body molded by mould with the second housing 2 that journal stirrup 2d is installed, and the Design of Dies difficulty is large, and installation journal stirrup 2d in use easily deforms, and it is unreliable to locate.
The utility model content
The utility model aims to provide a kind of automobile steering device housing structure, can prevent housing rotary.
For this reason, a kind of automobile steering device housing structure that the utility model provides, by the first housing, the second housing and be arranged on the first housing and the second housing between adapter shaft press-fit and form, be provided with the orthogonal tooth bar shell of axis on the second housing, gear hub and set screw mounting hole, described tooth bar shell and the coaxial setting of adapter shaft, gear hub be positioned at the tooth bar shell directly over, the set screw mounting hole site is in the dead ahead of tooth bar shell, key is: described first, on the second housing respectively fixed cover Anti-rotary block is housed, the periphery of described Anti-rotary block is by upper plane, back plane, lower plane and front arc surround, and described Anti-rotary block is made by aluminum alloy.
Be preferably, the interior thickness of described Anti-rotary block with economical with materials, reduces cost less than two ends thickness.
Beneficial effect: by being set with Anti-rotary block at steering gear housing, efficiently solve the problem of steering gear housing rotation, simple in structure, be skillfully constructed, easy to implement; Anti-rotary block and housing are distinguished moulding, greatly reduce the difficulty of processing of housing, have reduced the manufacturing cost of steering gear housing; Anti-rotary block has utilized the installation site of former gum cover, and gum cover no longer is set, and compares the structure before improving, and does not need to install by screw, and is quick and easy for installation, time saving and energy saving.
Description of drawings
Fig. 1 is the structure before improving.
Fig. 2 is the structure after improving.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the utility model is described in further detail:
A kind of automobile steering device housing structure as shown in Figure 2 is comprised of the first housing 1, the second housing 2 and adapter shaft 3 etc.Adapter shaft 3 is arranged between the first housing 1 and the second housing 2, and the first housing 1 and the second housing 2 are fitted in the two ends of adapter shaft 3.
Be provided with the orthogonal tooth bar shell of axis 2a, gear hub 2b and set screw mounting hole 2c on the second housing 2, be respectively applied to install tooth bar, gear and set screw.Tooth bar shell 2a and adapter shaft 3 coaxial settings, gear hub 2b be positioned at tooth bar shell 2a directly over, set screw mounting hole 2c is positioned at the dead ahead of tooth bar shell 2a.On the first housing 1 and the second housing 2 respectively fixed cover Anti-rotary block 4 is housed, when arranging, Anti-rotary block 4 is positioned on the former steering gear housing position that gum cover is installed, and the periphery of Anti-rotary block 4 is surrounded by upper plane 4a, back plane 4b, lower plane and front arc 4c, and Anti-rotary block 4 is made by aluminum alloy.Be preferably, the interior thickness of Anti-rotary block 4 is less than two ends thickness.
Claims (2)
1. automobile steering device housing structure, by the first housing (1), the second housing (2) and be arranged on the first housing (1) and the second housing (2) between adapter shaft (3) press-fit and form, be provided with the orthogonal tooth bar shell of axis (2a) on the second housing (2), gear hub (2b) and set screw mounting hole (2c), described tooth bar shell (2a) and the coaxial setting of adapter shaft (3), gear hub (2b) be positioned at tooth bar shell (2a) directly over, set screw mounting hole (2c) is positioned at the dead ahead of tooth bar shell (2a), it is characterized in that: described first, the second housing (1,2) on respectively fixed cover Anti-rotary block (4) is housed, the periphery of described Anti-rotary block (4) is by upper plane (4a), back plane (4b), lower plane and front arc (4c) surround, and described Anti-rotary block (4) is made by aluminum alloy.
