Description
Technical field:
The present invention relates to a kind of electric power-assisted steering tubular column assemblies.
Background technique:
Raising with auto parts and components development level and consumer to the handling demand of automobile, it is more and more riding
Vehicle starts to carry electric boosting steering system, on the one hand such structure can reduce integral vehicle cost, can be improved on the other hand
The steering behaviour of vehicle, so being widely applied rapidly.
The place nevertheless, such structure also comes with some shortcomings, if structure is more complicated, assembly occupied space is larger,
It is difficult to arrange at the beginning of design, and components are more heavy, it is more difficult in assembly, influence production capacity promotion.
Summary of the invention:
The present invention provides a kind of electric power-assisted steering tubular column assembly, in the case where not influencing components performance, by excellent
Change structure to improve the assembly process process of components.
The technical solution adopted in the present invention has: a kind of electric power-assisted steering tubular column assembly, including input shaft, upper bush,
Lower sleeve, assist motor, ECU, pull block, injection molding pin, upper mounting bracket, lower mounting bracket, torque sensor, deceleration mechanism,
Section fork and cross axle, the assist motor are connected with the input terminal of deceleration mechanism, and input shaft and section fork are connected to speed reducer
The output end of structure, input shaft is used and is molded, including enjoyable cooperation side is respectively adopted in upper and lower part, upper bush and lower sleeve
Formula is installed on the upper and lower part of input shaft, and upper mounting bracket and lower mounting bracket, which respectively correspond, is fixed on upper bush and lower sleeve
On, upper mounting bracket with pull between block using injection molding pin be connected, cross axle with save pitch is connected, ECU is installed on assist motor,
Torque sensor is installed in deceleration mechanism.
Further, the upper mounting bracket is all made of punching press with lower mounting bracket and is made.
Further, the torque sensor is non-contact torque sensor.
Further, the deceleration mechanism is turbine worm reducer structure.
Further, the power of the assist motor is 400w, rated speed 1300rpm, rated current 3.0Nm.
The invention has the following beneficial effects: the configuration of the present invention is simple, convenient for assembly.
Detailed description of the invention:
Fig. 1 is cross-sectional view of the present invention.
Fig. 2 is structure of the invention figure.
Specific embodiment:
The present invention will be further described below with reference to the drawings.
Such as Fig. 1 and Fig. 2, a kind of electric power-assisted steering tubular column assembly of the present invention, including input shaft 1, upper bush 2, lower sleeve
3, assist motor 4, ECU5, pull block 6, injection molding pin 7, upper mounting bracket 8, lower mounting bracket 9, torque sensor 10, speed reducer
Structure 11, section fork 12 and cross axle 13, assist motor 4 are connected with the input terminal of deceleration mechanism 11, and input shaft 1 and section fork 12 connect respectively
Connect the output end in deceleration mechanism 11, input shaft 1 is using being molded, including top 111 and lower part 112, upper bush 2 and traps
The upper and lower part that enjoyable fit system is installed on input shaft 1 is respectively adopted in cylinder 3, and upper mounting bracket 8 and lower mounting bracket 9 are distinguished
Correspondence be fixed on upper bush 2 and lower sleeve 3, upper mounting bracket 8 with pull between block 6 using injection molding pin 7 be connected, cross axle 13
It is connected with section fork 12, ECU5 is installed on assist motor 4, and torque sensor 10 is installed in deceleration mechanism 11.
