Description
Technical Field
The utility model relates to an automobile parts technical field, specificly relate to a novel steering drive shaft support.
Background
In the field of commercial vehicles, a steering transmission shaft fixing bracket mainly plays a role in keeping a transmission shaft stable, so that the transmission of steering wheel torque is guaranteed, and the steering transmission shaft fixing bracket is a necessary part for realizing steering. The fixing mode of the steering transmission shaft fixing support is very important for the overall arrangement of the steering transmission shaft, and whether the arrangement reasonably and directly affects the reliability of the support. Therefore, the design of the steering transmission shaft support needs to consider not only the arrangement relationship between the transmission shaft and the vehicle body, but also the structural form of the transmission shaft fixing support and the requirements on strength and cost.
At present, a steering transmission shaft fixing type adopts a die-casting aluminum structure, a steering lower transmission shaft is fixed on a chassis support through an aluminum alloy support, the aluminum alloy support is subjected to failure damage due to motion torsion and vibration swing of the transmission shaft, a huge amount of mold and equipment cost needs to be invested by adopting the structure, and the ductility of an aluminum alloy material is far weaker than that of a carbon steel material, so that the design of a novel steering transmission shaft support for solving the problems is particularly important.
Disclosure of Invention
The utility model discloses a solve above-mentioned problem and designed a novel steering drive shaft support, through changing the fixed type into and fix on driver's cabin suspension support, played the effect that reduces structure size and reduce cost.
In order to solve the technical problem, the utility model provides a novel steering transmission shaft support which characterized in that: the steering transmission mechanism comprises an upper steering transmission shaft, a lower steering transmission shaft and a rotation shaft fixing support, wherein a steering device connecting piece and a first transmission connecting piece are arranged at the upper end and the lower end of the upper steering transmission shaft respectively, the lower steering transmission shaft is connected with the upper steering transmission shaft, the lower steering transmission shaft is arranged on a cab suspension support through the rotation shaft fixing support, the lower steering transmission shaft and the rotation shaft fixing support can rotate relatively, a second rotation connecting piece and a third transmission connecting piece are arranged at the upper end and the lower end of the lower steering transmission shaft respectively, and the lower steering transmission shaft is connected with the first transmission connecting piece of the upper steering transmission shaft through the second rotation connecting piece.
Further: the rotating shaft fixing support is composed of a rotating positioning sleeve, a supporting seat and a connecting frame, the supporting seat and the connecting frame are both made of carbon steel materials, the steering lower transmission shaft penetrates through the rotating positioning sleeve and is in rotating connection with the rotating positioning sleeve, the rotating positioning sleeve is fixed to the top of the supporting seat, and the supporting seat is connected to the cab suspension support through the connecting frame.
And further: the upper end of the upper steering transmission shaft is also connected with an extension rod body, one end of the extension rod body is fixedly connected with the upper steering transmission shaft, and the steering gear connecting piece is arranged at the other end of the extension rod body.
And further: the diameter of the extension rod body is smaller than that of the steering upper transmission shaft.
After the structure is adopted, the utility model changes the fixing type into the fixing type on the suspension bracket of the cab, thereby playing the roles of reducing the structure size and the cost; the utility model adopts carbon steel material to replace aluminum alloy material, and improves reliability by replacing material; and the design also has the advantages of simple structure, easy manufacture, practicality and high efficiency.
