Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in detail.The identical Reference numeral of wherein identical parts represents.It should be noted that, the word "front", "rear" of use is described below, "left", "right", "up" and "down" refer to direction in accompanying drawing, word " interior " and " outward " refer to the direction towards or away from particular elements geometric centre respectively.
The control system overall structure schematic diagram of the car steering tube column that Fig. 1 provides for the utility model embodiment, the control system decomposing schematic representation of the car steering tube column that Fig. 2 provides for the utility model embodiment, the control system cross sectional drawing of the car steering tube column that Fig. 3 provides for the utility model embodiment.
The utility model embodiment provides a kind of control system of car steering tube column, comprises steering column 1, upper bracket 2, clamp bracket 3, oppositely cam 4 and handle assembly 5.
Wherein, described clamp bracket 3 is fixedly installed on the outer wall of described steering column 1.As shown in Figure 1 to Figure 3, clamp bracket 3 can be fixed by welding on the outer wall of the below of steering column 1, and clamp bracket 3 is provided with bar hole, passes for the bolt 51 in handle assembly 5.Upper bracket 2 is positioned at the top of steering column 1, and upper bracket 2 comprises the pair of side plates be oppositely arranged, and described side plate clamps described clamp bracket 3.Each side plate is provided with bar hole, is pass for the bolt 51 in handle assembly 5 equally.
Handle assembly 5 comprises handle 52, bolt 51 and cam 53, reverse cam 4 is between cam 53 and the first side plate 21 of upper bracket 2, after second side plate 22 of above-mentioned bolt 51 successively through the first side plate 21 of described handle 52, cam 53, oppositely cam 4, upper bracket 2, clamp bracket 3 and upper bracket 2, locked by jam nut 6.As can be seen from Figure 2, the first side plate 21 and the second side plate 22 are provided with strip hole 23, pass for bolt 51.
The locking of above-mentioned handle assembly 5 relies on projection that cam 53 and reverse cam 4 are arranged respectively and groove to realize.When the projection correspondence in the projection on cam 53 and reverse cam 4 holds out against, handle assembly 5 is locking state, when groove corresponding matching in the projection on cam 53 and reverse cam 4, handle assembly 5 is open mode, when handle assembly 5 is open mode, can regulate steering column 1.
Fig. 4 is the partial enlarged drawing in Fig. 1, incorporated by reference to Fig. 2 to Fig. 4, the control system of above-mentioned car steering tube column also comprises precompressed gripping members 7, this precompressed gripping members 7 is arranged between the second side plate 22 and described jam nut 6, and described precompressed gripping members 7 has the rigidity of setting to produce the predetermincd tension of setting to described second side plate 22.When handle 52 is opened, precompressed gripping members 7 continues to produce thrust to the second side plate 22 of upper bracket 2, thus avoids and between all parts, relative movement occur and produce noise.Because this precompressed gripping members 7 has the rigidity of setting, certain elastic deformation can be there is, thus the adjustment of steering column 1 can not be affected.
It will be appreciated by persons skilled in the art that the rigidity of precompressed gripping members 7 can arrange according to concrete pre-pressing force and regulate, do not do concrete restriction at this.
