And leave a hole in the middle for the steering intermediate shaft to pass through and rotate. Because there is a gap in the bolt hole, and the bolt is easy to loosen, water will flow from the gap in the bolt hole, the body sheet metal and rubber Leakage in the gap of the steering intermediate shaft, resulting in poor sealing of the steering intermediate shaft, prone to water leakage, and unable to meet the requirements of the wading test

The invention relates to the technical field of automobile mounting structures, and discloses a mounting structure of an automobile steering intermediate shaft, which comprises a steering intermediateshaft, a sealing piece, a pressing piece and a locking piece, a first mounting hole and a second mounting hole are formed in the sealing piece and the pressing piece respectively, the pressing pieceis arranged on the rear side of the sealing piece, and the front side of the sealing piece abuts against an automobile body. A first connecting hole is formed in the sealing piece, a second connectinghole corresponding to the first connecting hole is formed in the pressing piece, the locking piece sequentially penetrates through the second connecting hole and the first connecting hole and then isconnected with an automobile body in a fastened mode, and at least one circle of sealing groove surrounding the first mounting hole is formed in the outer side of the sealing piece. A first sealant is arranged along the peripheral edge of the sealing groove, and at least part of the first connecting hole coincides with the sealing groove. By the adoption of the technical scheme, the mounting structure of the automobile steering intermediate shaft is convenient to install, the structure depending on rubber waterproofing in an existing product structure is changed, the sealing effect is good, and the stricter waterproof requirement can be met.
Description
technical field [0001] The invention relates to the technical field of automobile installation structures, in particular to an installation structure for an automobile steering intermediate shaft. Background technique [0002] The steering intermediate shaft is an important transmission part of the automobile steering system and an important safety guarantee component on the automobile. It is used in the steering column and the steering machine to transmit the driver's steering control action to the steering actuator, which mainly plays the role of transmitting motion. role. Since the layout of the transmission shaft spans the cockpit and the engine compartment, the working environment is relatively complex, so it is required to have high reliability to adapt to the use requirements under different working conditions and ensure the normal driving of the vehicle. [0003] At present, the steering intermediate shaft of many models on the market adopts a combined structure of ...
