Abstract
The invention discloses a steering gear for a motor vehicle. The steering gear comprises a steering shell, a sector steering gear, a steering shaft, a steering gear shaft and a steering rack. The steering rack is arranged on the steering shaft. The steering shaft is provided with a concave part. The steering rack is arranged on the concave part. The depth of the concave part is larger than the tooth height of the steering rack. The steering gear for the motor vehicle is simple in structure and high in safety.
Description
Technical field
The present invention relates to a kind of steering gear, particularly a kind of motor turning device.
Background technology
Steering gear is requisite part in motor vehicle fittings, present most of steering gear all utilizes tooth sector and steering rack engaged transmission to realize direction transmission, turn in housing owing to tooth sector and steering rack are arranged on, their engagement situation cannot be observed, likely because of motor vehicle driver ovdersteering, the meshing gear of tooth sector and steering rack can be mutually disengaged, make to turn to out of hand, cause the situation of causing danger.
Summary of the invention
The goal of the invention of the present invention is in that: for above-mentioned Problems existing, it is provided that a kind of motor turning device that can limit steering gear steering angle.
The technical solution used in the present invention is such that a kind of motor turning device, including turning to housing, fan-shaped tooth sector, steering spindle, tooth sector axle and steering rack, steering rack is arranged in steering spindle, described steering spindle is provided with a concave shaped portion, steering rack is arranged in concave shaped portion, and the degree of depth of concave shaped portion is more than the tooth depth of steering rack.
The invention has the beneficial effects as follows: simple in construction, high safety.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Labelling in figure: 1 for turning to housing, 2, fan-shaped tooth sector, 3, steering spindle, 4, tooth sector axle, 5, steering rack, 6, concave shaped portion.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
In order to make the purpose of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1, a kind of motor turning device, including turning to housing 1, fan-shaped tooth sector 2, steering spindle 3, tooth sector axle 4 and steering rack 5, steering rack 5 is arranged in steering spindle 3, described steering spindle 3 is provided with a concave shaped portion 6, steering rack 5 is arranged in concave shaped portion 6, and concave shaped portion 6 degree of depth is more than the tooth depth of steering rack 5；During the work of motor turning device, fan-shaped tooth sector 2 engages with steering rack 5, rotates fan-shaped tooth sector 2 and just by driving steering spindle 3 to move to a direction with the meshed transmission gear of steering rack 5, can realize turning to of motor vehicles with this；Owing to steering rack 5 is provided in the concave shaped portion 6 of steering spindle 3, when fan-shaped tooth sector 2 engages in a direction transmission process with steering rack 5, fan-shaped tooth sector 2 finally will with one end step touching of concave shaped portion 6 in steering spindle 3, after touching, fan-shaped tooth sector 2 is withstood by one end step of concave shaped portion 6, cannot be further continued for rotating, it is achieved thereby that the steering angle of motor turning device is limited, do not have and turn to too quickly and turn to unsafe condition out of control, substantially increase the safety of motor turning device, and simple in construction.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent replacement and improvement etc. made within the spirit and principles in the present invention, should be included within protection scope of the present invention.
